1) What are the advantages & disadvantages to the proposed recommendations in the article?
The article recommends adopting a modified Robinson-Ho Skin Type Color Bar as an objective, standardized tool for baseline skin tone assessment in patients with dark skin tones. This is proposed to complement standard visual/tactile skin assessments, improve early detection of skin injuries (especially pressure injuries), enhance documentation, and reduce over-reliance on subjective race or ethnicity categories. Advantages: • Promotes health equity by helping clinicians better identify subtle skin changes (e.g., purple/maroon discoloration or hyperpigmentation) that are often missed in darker skin tones. • Provides a reliable method for documenting baseline skin tone with moderate inter-rater reliability, supporting consistent tracking over time. • Supports staff education, training, and integration into electronic health records or mobile documentation systems. • Low-cost, non-invasive, and easy to combine with existing practices like photography and proper lighting/moisturizing techniques. Disadvantages: • In this pilot study, the tool was not effective at detecting subtle early skin injuries due to sudden-onset wounds and pigmentation masking effects. • Practical challenges include variation in skin tone across body sites (e.g., sacrococcygeal area vs. other regions), lighting conditions, patient positioning, and added workflow steps. • Limited generalizability due to small sample size, critical care setting, and need for staff training/resources.
2) Describe the method used by the author of the study.
The authors conducted a prospective, observational cohort pilot study in a surgical intensive care/acute care unit (SICU/ACU) at NYU Langone Health. Key elements: • Sample: 42 adult participants (≥18 years old, mean age ~50) with confirmed dark skin tones based on the modified Robinson-Ho scale and no existing skin injury at enrollment. Mostly Black (76%), with exclusions for cognitive impairment, end-of-life care, etc. • Tool: A modified version of the Robinson-Ho Skin Type Color Bar focusing on darker shades (rows 3–6), with added numbering for documentation, a centimeter ruler, and fields for patient details, date, and location. • Procedures: Baseline assessments of high-risk areas (sacrococcygeal region and heels) using the color bar tool plus standard visual/tactile evaluation and photography by two independent raters. Daily assessments (Monday–Friday) followed the same sequence until discharge or skin injury (up to 3 months). Skin was prepared with cleansing and moisturizing under consistent lighting. • Analysis: Descriptive statistics for demographics; Fleiss Kappa for inter-rater reliability on baseline normal skin; data analyzed in SPSS v29. • Design: Aimed to test the tool’s ability to detect injury-related skin tone changes and inter-rater reliability. IRB-exempt status with informed consent obtained.
Describe the method used by the author of the study.
The researchers conducted a prospective observational cohort pilot study over a 12-month period in a surgical intensive care and acute care unit at an urban academic hospital. Adult patients with dark skin tones who did not already have a skin injury were enrolled and received daily skin assessments using both the modified Robinson-Ho Skin Type Color Bar and the standard visual and tactile skin assessment. Baseline skin tone measurements and photographs of the sacrococcygeal area and heels were collected, and participants were monitored until discharge or until a skin injury developed. To evaluate the reliability of the tool, both a research nurse and a clinical nurse independently assessed each participant's baseline skin tone, and the researchers used statistical analysis to measure agreement between raters.
Discuss the sample size used in the study.
The pilot study included a final sample of 42 adult patients with dark skin tones. The researchers originally planned to recruit 44 participants, but data collection ended after one year because they determined that sample saturation had been reached. Participants were recruited from a surgical intensive care and acute care unit and had to be at least 18 years old, have no existing skin injuries, and meet the study's criteria for dark skin tone using the modified Robinson-Ho Skin Type Color Bar. Although the sample size was relatively small, it was considered appropriate for a pilot study designed to evaluate the feasibility and reliability of the assessment tool before conducting larger studies.
The sample size for this pilot study was 44 patients. This number was based on the team’s prior experience and feasibility for conducting work with this population. The pilot study achieved a total sample size of 42, because of sample saturation. At 1 calendar year since the beginning of data collection, the study team agreed that saturation had been reached. The pilot study sample consisted of 42 participants with a mean age of 50.31. OF the total participants, 57% were male, 76% identified themselves as Black, and 67% identified as not of Spanish/Hispanic origin.
Discuss the research question or main problem discussed in the study?
The objective of this study was to determine whether a modified version of the Robinson-Ho Skin Type Color Bar would identify early, subtle skin tone variations in patients with dark skin tones because of injury. They also were trying to determine if the tool was reliable between clinicians. The purpose of this research was to determine whether the addition of an objective, noninvasive skin tone measuring guide to the standard visual/tactile skin assessment process would assist in identifying warning signs of a skin injury.
1. Discuss the research question or main problem discussed in the study?
The study looks at the difficulty of identifying early skin injuries in people with dark skin tones. Changes in skin color are often harder to see, which can delay treatment and allow the injury to become more serious. The researchers wanted to find out if the modified Robinson Ho Skin Type Color Bar could help healthcare professionals detect these early skin changes more accurately and consistently.
2. What are the advantages and disadvantages to the proposed recommendations in the article?
Advantages The recommendations can help healthcare professionals identify skin injuries earlier in patients with dark skin tones. Earlier detection allows treatment to begin sooner and may prevent the injury from becoming more serious. The color bar also gives healthcare professionals a simple and more consistent way to check for changes in skin color, which can improve patient care. Disadvantages The study was done with a small group of participants, so the results may not apply to everyone. Healthcare professionals may also need training to use the color bar correctly. More studies are needed to make sure the tool works well in different hospitals and with a larger number of patients.
1. Discuss the limitations of the article; limited sample size; design; flaws and/or author bias?
* The tool used in this article has a flaw because it was unable to account for the different variation in skin tones especially on the sacrococcygeal area and heels. The modified Robinson-Ho Skin Type Color Bar tool was unable to include the patient's clinical conditions, where skin tone changes were not noted because of critical illness. The study also did not have funding for translation and interpreter services therefore the study was not able to include non-English patient.
2. Discuss the research question or main problem discussed in the study?
* The research study utilized the modified Robinson-Ho Skin Type Color Bar to determine if it could assist in identifying warning signs of a skin injury. Robinson-Ho Skin Type Color Bar was created to accomodate possible skin tone options ranging from light to dark skin tones. Clinicians used this skin tone assessment for determining a patient's risk for misidentification and developing a wound because of pigmentation. The study's use of modified Robinson-Ho Skin Type Color Bar in addition to visual/tactile skin assessment can help in patients with dark skin tones. The study showed that race and ethnicity are not a reliable indicators of skin tones, but the use of modified Robinson-Ho Skin Type Color Bar in this study helped identify early skin injuries in patients with dark skin tones.
1. What are the advantages and disadvantages to the proposed recommendations in the article? The article recommends using an objective skin tone assessment tool instead of relying on race or ethnicity to identify patients with dark skin tones who may be at risk for delayed skin injury detection. One advantage is that the tool provided a reliable way for different clinicians to identify baseline skin tone and could help improve consistency in assessments. Another advantage is that it promotes more equitable care for patients with dark skin tones. However, the study found that the tool was not effective at detecting early subtle skin changes that signaled injury, limiting its usefulness. The authors also suggested that newer technologies may be more effective, but these could be more expensive and harder for hospitals to implement.
2. Discuss the research question or main problem discussed in the study. The main research question was whether a modified Robinson-Ho Skin Type Color Bar could help clinicians detect early skin injuries in patients with dark skin tones and whether different clinicians could use the tool consistently. The study focused on the problem that skin injuries are often harder to recognize in darker skin, which can delay treatment and lead to worse outcomes. Researchers found that the tool was reliable for identifying baseline skin tone, but it did not successfully detect early skin injury changes in this pilot study. The findings also showed that race and ethnicity are not accurate ways to determine skin tone. Overall, the study highlights the need for better methods to identify skin injuries early in patients with dark skin tones.
1. Discuss the research question or main problem discussed in the study?
The primary issue addressed in this study is the continuous difference in the detection and prevention of pressure injuries (PIs) among individuals with darker skin tones. Evidence suggests that individuals with dark skin had a higher incidence, severity, and death rate from pressure injuries, which may be due to the difficulty of detecting early-stage pressure injuries using typical visual evaluation methods. Current assessment techniques frequently focus on race or ethnicity rather than objective measures of skin tone, which can result in delayed detection and treatment. The study sought to see if adding an objective, noninvasive skin tone measurement guide to the standard visual and tactile skin assessment could improve the early detection of pressure injury warning signs and promote more equitable skin assessments across diverse skin tones.
2. Describe the method used by the author of the study
This pilot study used a prospective observational cohort design with inter-rater reliability testing to determine the efficacy of an objective skin tone assessment tool for detecting early pressure injury early warning signs in patients with dark skin tones. The study was conducted over a 12-month period in an acute and critical care unit of a big metropolitan academic medical center and was exempt from the institutional review board (IRB). Adult patients (18 years and older) hospitalized to the surgical intensive care unit (SICU) or acute care unit (ACU) with proven dark skin tones, as established by the modified Robinson-Ho Skin Type Color Bar, were eligible to participate. Patients undergoing hospice or end-of-life care, those with prior skin injuries, deceased organ donors, and those with cognitive impairment were eliminated. All subjects provided informed consent before to registration. The prospective design enabled researchers to track changes in each patient's baseline skin tone and determine whether adding an objective skin tone assessment improved the early detection of pressure injuries in individuals with darker skin tones.
Describe the method used by the author of the study:
The design method of this study is a prospective, observational cohort study. Over 12 months, the study sought to identify patients with dark skin tones and then observed how skin toned varied with skin injuries within that population of patients. A prospective method was chosen in order to accurately differentiate between injured and uninjured patients with darker skin tones. This was an important decision, because the literature supported the idea that dark skinned patients typically have more severe wounds at the time of reporting because early identification is often missed in this population.
Discuss the limitations of the article:
The study was unable to account for the wide variation of skin tones on the sacrococcygeal area and heels of patients included in the study. The study utilized a modified version of the Robinson-Go Skin Type Color Bar, but this tool was not vast enough to represent all patients, and also did not accommodate for changes in clinical conditions that affected the patient’s skin due due to critical illness (perfusion, etc). The patients studied during this 12-month period were less clinically complex than the unit typically cares for, so the results of the study may not be reflective of normal operations. Another factor was the exclusion of non-English speaking patients within the study due to translation service cost, which excluded a large portion of vulnerable, melanated individuals.
Discuss the research question or main problem discussed in the study?
The research question in this study is to see whether a modified version of the Robinson-Ho Skin Type Color Bar would assist nurses in identifying skin tone variations in patients with dark skin tones because of injury. A darker skin tone can make identifying pressure and skin injuries more difficult to identify early on. The lack of identification can delay treatment or preventative measures for those with darker skin tones in this patient population.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias
This study had some limitations, such as the inability to accommodate changes in clinical conditions where skin tone changes were noted, due to perfusion or hypoxia or other conditions that may affect skin tone changes. The conductors of this study were unable to use translation and interpretation services due to funding, therefore were unable to include any non-English speaking participants. Further limiting the study, the unit population was less critically ill than the usual population of patients admitted on the unit.
Discuss the research question or main problem discussed in the study.
The main problem addressed in this study is the critical lack of equitable resources and clinical knowledge for identifying skin injuries in patients with dark skin tones. I have observed that early warning signs of pressure injuries such as non-blanchable erythema are often missed because darker pigmentation can mask the typical redness clinicians are trained to look for. This often results in delayed detection that leads to more severe wounds, and ultimately contributes to higher rates of morbidity, mortality, and treatment. The main question focuses on whether integrating an objective modified version of the Robinson-Ho Skin Type Color Bar can help clinicians identify early subtle skin tone variations indicative of injury over high risk areas like the heels and sacrococcygeal region. By evaluating the tool's inter-rater reliability among clinical staff, they intended to introduce a more objective marker for skin tone assessment instead of subjective and often unreliable categories such as self reported race or ethnicity.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The most significant flaw is the small sample size of only 42 participants drawn from a single acute and critical care unit at one urban academic medical center. The limited sample size restricts makes it harder to generalize the findings to other patient populations or clinical settings especially as that unit’s patient population was less critically ill than usual during the study period. Another major design limitation emerged as no patients developed the early, subtle skin tone changes the tool was supposed to detect and the only two wounds that occurred were already highly visible. The tool also struggled to account for natural skin tone variations on the heels and sacrococcygeal area, and didn’t adequately accommodate other clinical factors like edema or mottling which further limited its practical effectiveness. Finally, excluding non English speaking patients due to a lack of funding for translators plus the absence of a formal cost benefit analysis represent missed opportunities to fully assess the tool’s usefulness in a broader clinical setting.
Discuss the research question or main problem discussed in the study.
The main problem discussed in this study was to determine if a modified version of the Robinson-Ho Skin Type Color Bar could identify subtle tone variation in patients with dark skin tones and if this tool was reliable between users. Skin tone plays a key role in proper skin assessment. The article notes that there was a higher incidence of advanced PIs in Black patients compared to White patients, likely because there was a missed identification of Stage 1 PI in patients with darker skin tones. One of our assessments, looking for non-blanching redness, can appear differently on dark skin tones.
Discuss the limitations of the article.
One limitation of this article was its lack of funding, which notably, did not allow the researchers to have translation and interpretation services. This caused the study to exclude non-English-speaking patients in their study. This is a larger oversight as there may have been many patients with dark skin tones that could have been included, but were not, simply because they did not speak English. In order to help address disparities in our healthcare system, special care should be taken with minority populations. While I appreciate this study in specifically studying patients with darker skin tones, another often overlooked minority population includes those who do not speak English. If they were to do another study like this, I hope they could get the funding for translation services to increase their study population to include non-English-speaking patients.
1. Describe the method used by the author of the study.
- The study used a prospective, observational cohort design to evaluate wether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify subtle skin-color changes associated with skin injury in patients with dark skin tones and wether different clinicians could use the tool consistently.
2. Discuss the limitations of this article.
- A major limitation of the study was the limited number of patients who developed skin injuries during the observation period. Only twi injuries occurred and neither demonstrated the subtle skin-color changes that the modified Robinson-Ho Color Bar was designed to identify. Consequently, the study could not establish the tool’s effectiveness for early detection of skin injury. In addition, the study was conducted in a single urban academic hospital which limits generalizability to other patient populations and healthcare settings.
The study found that the modified Robinson-Ho Skin Type Color Bar was not very effective at detecting early skin injuries in patients with dark skin tones. The researchers did find that the tool was reliable when different nurses used it to identify a patient’s normal skin tone. This shows that skin color alone may not be enough to identify an injury early. Nurses should also look at other changes such as skin texture, temperature, swelling, and pain.
2. How can the findings of this study be applied to patient care?
This study shows why nurses should use more than just skin color when checking patients with dark skin tones for injuries. Redness or other color changes can be harder to see, which could cause an injury to be missed. Nurses can use touch and look for changes in temperature, texture, pain, or swelling along with visual assessment. More complete skin assessments may help nurses identify pressure injuries earlier and prevent them from becoming more serious.
2. Identification of Skin Injuries in Patients With Dark Skin Tones
How does this research article compare to our practice, policy and/or procedure?
This study addresses a gap that is highly relevant to skin-integrity practice: early skin injury can be harder to recognize when clinicians rely mainly on visible redness. The modified Robinson-Ho Skin Type Color Bar provided a more objective way to document baseline skin tone and showed moderate agreement between clinicians. That approach is consistent with a skin-integrity program focused on early identification and prevention, although the study did not prove that the tool detects early injury reliably (Savage et al., 2026; Providence, 2026a).
What are the advantages and disadvantages to the proposed recommendations in the article?
Advantages. The strongest potential benefit is more consistent baseline documentation of skin tone. It may also remind nurses not to use race or ethnicity as a substitute for an actual skin-tone assessment. A standardized baseline could make later changes easier to recognize and communicate between clinicians.
Disadvantages. The tool adds another assessment step, and the pilot study did not demonstrate that it could identify subtle early injury changes. Training would be needed to use it consistently, and relying on the color bar alone could be unsafe because pressure-injury assessment also requires tactile findings, temperature, pain, tissue consistency, and other clinical observations.
Describe the method used by the author(s) of the study.
The authors used a prospective observational cohort design in a surgical intensive care/acute care unit at an urban academic hospital. Adults with dark skin tone and no skin injury at enrollment were followed using the modified Robinson-Ho Skin Type Color Bar (Savage et al., 2026).
Discuss the research question or main problem discussed in the study.
The study asked whether the modified color bar could identify early subtle skin-tone changes caused by injury in patients with dark skin tones and whether different clinicians could use the tool reliably.
Discuss the sample size used in the study.
The pilot enrolled 20 patients. Only two developed a skin injury during the study, and those injuries did not present as the subtle color changes the tool was intended to detect (Savage et al., 2026).
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The very small sample is the main limitation. Only two patients developed skin injuries, so the investigators could not adequately test the tool's ability to detect subtle early changes. The study was also performed in a single clinical setting. These factors limit generalizability and make the findings preliminary.
1. Describe the method used by the author of this study The study used a prospective observational cohort design over a 12-month period to evaluate whether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify skin color changes associated with early skin breakdown in patients with dark skin tones. Researchers identified patients with darker skin pigmentation and then monitored them over time to observe how skin tone changed when injuries developed versus patients who remained injury free. The study also examined whether different clinicians could use the modified color bar consistently during skin assessments.
2. Discuss the limitations of the article. One major limitation was the small number of skin injuries observed during the 12-month study period. Another limitation was the exclusion of non-English speaking patients. This is not representative of the patient population found at St. Joseph. This exclusion reduced the diversity of the sample.
1. Describe the method used by the author of the study.
- The study used a prospective, observational cohort design to evaluate wether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify subtle skin-color changes associated with skin injury in patients with dark skin tones and wether different clinicians could use the tool consistently. The methodology was appropriate for an early pilot study because the researchers were testing a relatively new approach in a real clinical environment. The prospective design allowed them to establish patient’s baseline skin tone before any injury occurred and then observe what happened overtime.
2. Discuss the limitations of this article.
- A major limitation of the study was the limited number of patients who developed skin injuries during the observation period. Only two injuries occurred and neither demonstrated the subtle skin-color changes that the modified Robinson-Ho Color Bar was designed to identify. Consequently, the study could not establish the tool’s effectiveness for early detection of skin injury. In addition, the study was conducted in a single urban academic hospital which limits generalizability to other patient populations and healthcare settings.
1. Discuss the research question or main problem discussed in the study.
- The main problem discussed in this study is the difficulty of identifying early skin injuries, including pressure injuries, in patients with darker skin tones. Subtle changes in skin color can be harder to recognize in darkly pigmented skin, which may lead to delayed identification and treatment of skin damage. The researchers examined whether a modified Robinson-Ho Skin Type Color Bar could provide a more objective way for clinicians to identify a patient's baseline skin tone and recognize subtle changes that may indicate injury. They also wanted to determine whether different clinicians could use the tool consistently. Improving early recognition of skin changes is important for bedside nurses because earlier identification can allow preventive interventions to be started before the injury progresses.
2. What are the advantages and disadvantages to the proposed recommendations in the article?
- One advantage of the recommendation is that the modified Robinson-Ho Skin Type Color Bar could help nurses identify and document a patient's baseline skin tone more objectively. This may make skin assessments more consistent between nurses and help reduce the risk of missing early skin changes in patients with darker skin tones. It could also increase staff awareness that redness may not be as visible in darker skin and that other changes, such as differences in temperature, texture, firmness, pain, or discoloration, should also be assessed. A disadvantage is that the study did not provide enough evidence that the tool can reliably detect early skin injuries, and the injuries did not show the subtle color changes the researchers were looking for. The tool would also require staff education, practice, and additional assessment time. It should be used as one part of a complete skin assessment rather than relied upon alone. More research with larger and more diverse patient populations is needed before it can be adopted as a standard tool.
1. Describe the method used by the author of the study. The method used by the authors in this study was done over a 12 month period. The objective was to identify patients with dark skin tones and observe how skin tone varied with skin injuries. The setting was an acute and critical care unit within a large urban hospital. The study utilized the modified Robinson-Ho skin type color bar.
2. Discuss the sample size used in the study. The goal sample size for this study was 44 patients. However, the pilot study achieved a total sample size of 42 patients due to sample saturation. The study participants were adults age 18 years and older who remained in the unit of the study during that duration. The exclusion criteria was end of life or hospice, pre-existing skin injury or had cognitive impairment.
Q: Discuss the research question or main problem discussed in the study. A: The main research question was had 2 parts. 1) Whether a modified Robinson-Ho Skin Type Color Bar could help clinicians detect early skin injuries in patients with dark skin tones. 2) Whether the modified tool could be used by different clinicians to make objective assessments. The problem being that the early signs of skin injuries are often harder to recognize in darker skin, resulting in delays in treatment and poorer outcomes. The first aim was unsuccessful because there were not enough individuals who developed subtle skin tone differences in the early stages of injury. The second aim was modestly successful and showed some agreement between users.
Q: Discuss the limitations of the article: limited sample size, design flaws, and/or author bias. A: The primary limitation was the small sample size (42) and that they were taken from a single unit at one urban medical center. This sample size was simply not large enough to accommodate all the mitigating factors that prevented a truly objective study. Environmental factors, socio-economic factors, cultural differences, etc. were not able to be studied or accounted for in such a small sample. There is simply too great a variation in skin tones (from person to person and within the same body) to be able to evaluate patients with darker skin objectively, using one limited tool. Pre-existing and co-existing medical conditions that affect skin tone were the second most limiting factor. Caregivers struggled to use a limited tool when considering complicated clinical factors that affect skin tone, like edema, infection, perfusion or circulatory problems like PAD, and diabetes.
Discuss the research question or main problem discussed in the study?
The main problem discussed in the study is that early skin injuries like developing pressure injuries can be difficult to recognized in patients with darker skin tones. This study is aimed to determine if a modified version of the Robinson-Ho skin type color bar could be used to detect early skin changes on patients with darker skin tones. Skin assessment relies heavily on the visual assessment of the bedside nurse. Developing pressure injuries star with changes to the skin like new redness, however skin color change may be more subtle on darker skin tones and therefore may result in delayed recognition.
Discuss the sample size used in the study. This study took place in a surgical ICU and included all the adult patients with dark skin tones on that unit that did not initially have a skin pressure injury. The total number of participants was 42, during this study only a small number of participants developed skin injuries, two patients is a small number to gather data from. Therefore, the study could not adequately assess if the use of the Robinson-ho skin type color bar was an appropriate tool to detect subtle skin changes. The tool that was being used could not account for the wide variation of skin tones/pigmentation. One challenge that was mentioned in the study was when using the skin tone rules to assess the sacrococcygeal area, they saw that many patients had different skin tones that deviated from their baseline skin tone.
Q. Discuss the research question or main problem discussed in the study? A. Skin assessment is important nursing skill each nurses need to develop. Every patient is different thus dark skin color may be true to be challenging in some patients combined with other factors. This study seeks to know if using the modified Robinson- Ho Skin type color bar can help in detection of pressure skin injuries. With this tool, and keen eye and touch will assist in detection and thus preventing pressure injuries. In previous studies, patients with dark skin tones have an increased incidence and severity of pressure injuries and increased risk of mortality from these injuries. Past studies between Black and Hispanic showed increased development of pressure injuries than White participants. Nursing home residents that are Black had higher incidence of Stage 2,3,4 pressure injury than White residents. In acute and outpatient setting, Black patients have higher longer stay and expenses related to pressure injury than non-black patients.
Q. Discuss the sample size used in the study. A. The goal sample for this study is 44 patients but only 42 patients were used due to sample saturation. The study is done one whole calendar year. The setting for this study is in an acute critical care unit. Patients in critical care have greater chances of developing pressure injuries. Patient needs to be 18 years old and above who remained in the unit during the time of pilot study. The enrolled subjects also had a confirmed dark skin tone category based on their skin matching any of the tones on the modified Robinson-Ho Skin Type Color Bar. Patients were not included if they were (1) considered hospice, end-of-life, comfort care or deceased donor, (2) had a pre-existing skin injury, or (3) had cognitive impairment because of a disease process such as from a form of dementia.
1. Discuss the research question or main problem discussed in the study.
This study focused on finding skin injuries early in patients with darker skin tones. Skin changes can be harder to notice on darker skin, especially when looking for early signs such as changes in color. The researchers wanted to see if using a skin color tool along with the regular skin assessment could help nurses recognize these changes earlier. They also wanted to see if different nurses could use the tool and get similar results when assessing a patient’s skin tone.
2. Discuss the sample size used in the study.
The study included 42 adult patients with darker skin tones who were being cared for in an acute or critical care unit. The researchers originally planned to include 44 patients but completed the study with 42. During the study, only two patients developed skin injuries, and neither showed the subtle early skin changes the researchers were looking for. Because there were so few skin injuries, it was difficult to fully determine how effective the tool was at identifying early changes.
1.Discuss the research question or main problem discussed in the study?
The main problem discussed in this study is to determine whether the. modified Robinson-HO skin type color bar could provide assistance to healthcare providers in identifying early skin changes and injuries in patients with darker skin tones. This is an important topic to discuss as healthcare providers because the early signs of skin injuries (especially pressure injuries) can be difficult to be identified in darker skin tones. Typically, visual assessment is used to identify any signs of skin color changes or erythema. This problem is important in the healthcare system as it a lead to worsening tissue damage and cause an increase in patient complications.
2. Discuss the sample size used in the study
This study is limited in a sense that it only consisted of 42 adult participants with the average age of about 50 years old. Initially the goal of the sample size for this pilot research was 44 patients. In this study, 57% of the participants were identified as male. Additionally 76 % identified themselves as black and 67% identified as not of Spanish/Hispanic origin.
Discuss the research question or main problem discussed in the study? In this article fecal incontinence is being defined as the involuntary loss of rectal flatus, feces, and mucus for a period of at least one month in a person that was previously continent. There are many causes of fecal incontinence from IBS, various drugs like antibiotics, and consumption of stomach irritants like caffeine and alcohol. The article’s goal was to investigate if nursing care can prevent fecal incontinence. Some of the methods to help with fecal incontinence are dietary supplements, bowel training, and proper hygiene and skin care. Dietary fiber like psyllium has been shown to improve patient’s stool consistency and reduce the incidence of fecal incontinence, although the article states there is little evidence of this, I have cared for many patients in the acute care setting that also use psyllium and report no episodes of incontinence and overall healthy bowel movement patterns. Nurses play a crucial role in providing care for patient with fecal incontinence, from cleaning to assisting with timed toileting.
How does this research article compare to our practice, policy and/or procedure? In our ministry the recommendations/practices that this article is discussing are already in practice. Timed toileting time is a practice that I have seen implemented, especially in the rehabilitation unit, however the times that I have seen timed toileting being used, it has mostly been for urinary incontinence. The bedside nurse along with the help of the wound care team ensure proper skin care and hygiene practices are being followed, skin check procedure have been put in place to ensure that proper skin care is being followed when a patient is having incontinence episodes to prevent skin breakdown. The use of the “.skinassessment” phrase is used to assess a patient’s skin for pressure injuries, but within that checklist things like nutrition consult is included. When nutrition consults are done I have not seen psyllium fiber be recommended but other vitamins and supplements to support skin health are recommended.
1. Discuss the research question or main problem discussed in the study The main problem discussed in the study was the difficulty healthcare providers may have identifying early skin injuries, particularly pressure injuries, in patients with dark skin tones. Traditional methods often rely on visible redness, which can be harder to recognize on darker skin. The researchers examined whether a modified Robinson-Ho Skin Type Color Bar could help clinicians more accurately identify changes in skin color associated with skin injury. 2. Describe the method used by the author of the study The authors conducted a pilot study using the modified Robinson-Ho Skin Type Color Bar to assess skin changes in patients with dark skin tones. The researchers observed and assessed participants’ skin using the color bar to determine whether it could improve recognition and documentation of skin injuries. A pilot approach was appropriate because the tool was being evaluated for its usefulness and feasibility before larger studies are conducted.
Identification of Skin Injuries in Patients with Dark Skin Tones using a Modified Robinson-Ho Skin Type Color Bar: A Pilot Study
1. Discuss the sample size used in the study.
The targeted goal for the sample size was originally supposed to be 44. Although the study team all agreed that a sample size of 42 was sufficient. This was due to the saturation of the targeted population had been achieved. The participants had to be at least 18 years of age, no current skin breakdown issues, and be of darker skin tone to be considered a part of the study.
2. Discuss the research question or main problem discussed in the study.
The study was conducted to determine whether a skin tone-based guide would be beneficial to detect dark skinned people with skin injury changes more easily. For example, purple, blue, and burgundy color skin discoloration changes can be harder to differentiate in darker skinned participants. The study team wanted to attempt to use Robinson-Ho Skin Type Color bar to assess dark skinned people and help identify skin risk injuries earlier and appropriately.
Discuss the limitations of the article: Limited sample size, design flaws, and or author bias
One limitation of this study is the lack of data from a large sample group. The study itself only included data from 42 patients, in which the results from the data did not produce the changes in skin conditions they were hoping to evaluate. The study was also limited due to the fact that data collected was from only one surgical acute care unit, limiting how this study may affect different patient populations. The assessment tool for evaluating patients skin also had its limitations in regards to consistency when trying to determine a baseline for the patients skin conditions due to other factors such as lighting, positioning and vascular skin changes.
What are the advantages and disadvantages to the proposed recommendations in the article?
Although the data was limited, one big advantage of the proposed recommendations of this study include having another assessment tool to better understand, correctly evaluate and assess skin and the possibility of breakdown. The more tools we as nurses have available to us, help to improve our assessment skills and treatment plan. Although the study was aimed at creating better assessment tools for skin breakdown, a disadvantage to the study was that the results were inconclusive in regards to demonstrating skin changes they were hoping to evaluate.
1. Describe the method used by the author of the study. The authors conducted a prospective, observational pilot study using a modified Robinson-Ho Skin Type Color Bar to assess skin changes in patients with dark skin tones. The researchers enrolled 42 adult patients without existing skin injuries and performed baseline and daily skin assessments of the sacrococcygeal area and heels using the color bar along with standard visual and tactile assessments. They evaluated whether changes in skin tone could help identify early skin injuries and also compared assessments from different nurses to determine the tool’s inter-rater reliability. The pilot approach allowed the researchers to evaluate the tool’s usefulness and reliability before further research with a larger sample.
2. Discuss the research questions or main problem discusses in the study. The study focused on the difficulty healthcare providers may have in detecting early skin injuries, especially pressure injuries, in patients with dark skin tones. Traditional skin assessments often rely on visible redness or discoloration, which may be less noticeable or appear differently on darker skin. The researchers investigated whether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify subtle changes in skin color that may indicate an early skin injury. The study also examined whether the tool could provide a more consistent and objective way to assess skin tone among different healthcare providers.
Describe the method used by the author of the study
The method used in this study was a prospective, observational cohort design. The researchers picked a specific group, which in this case was dark skinned individuals, then checked their exposures and tracked the cohort into the future over a 12 month period. They then observed which patients developed pressure injuries depending on who had a greater presence of melanocytes that create dark skin tones.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias
The limitations of this study is the wide range of skin tones on the sacrococcygeal area and heels. The study also did account for the skin tone changes that occurred according to the acuity of the patient’s illness. Also during the study period, the SICU had less complicated patients than the normal so the study may not be reflective on the unit’s “normal” acuity. The study also did not have funding for translation services so they were not abla to include non English speaking patients.
Discuss the research question or main problem discussed in the study? Based on research findings, there has been a lack of knowledge and resources to identify pressure injuries in dark skin tones. Dark skin tones compared to white have increased incidence and severity of pressure injuries. Investigators believe the key reason is the missed assessment and early recognition. The main question of this study was to determine if the modified Robinson-Ho Skin Type Color Bar could help identify early skin changes in patients with dark skin tones. The authors also wanted to see if the tool was reliable.
Describe the method used by the author of the study. The method used by the authors was a prospective observational cohort study. The setting of this study was conducted in an acute critical care unit in large urban hospital. The modified Robinson-Ho Skin Type Color Bar was used to match dark skin tone category as baseline skin color assessment focused areas were on sacrum and heels, then monitor for skin changes.
1. Discuss the research question or main problem discussed in the study The main problem that is brought up in this article is that it is hard to determine skin injuries with people who have darker skin tone. Early signs of skin injury is erythema and with people that have darker skin tone; erythema isn’t as obvious which will cause a delay or missed identifications of skins injuries. The researchers studied whether a modified Robinson-Ho Skin Type Color Bar could provide a standardized method for assessing skin color and identifying skin injuries in patients with dark skin tones. 2. Describe the method used by the author of the study The authors used a small pilot study to see if the modified Robinson-Ho Skin Type Color Bar could help identify skin injuries with people who have darker skin tone. They participants skin is being examined and they used the color bar to identify and describe their skin color. They then looked for changes in skin color and other signs of skin injury.
1: Describe the method used by the authors of the study. A: The researchers conducted a prospective, observational cohort pilot study involving 42 adult patients with dark skin tones in a surgical intensive care and acute care unit. They used a modified Robinson- Ho Skin Type Color Bar alongside standard visual and tactile assessments to identify early signs of skin injuries. Researchers assessed the patients’ sacrococcygeal areas and heels at baseline and conducted daily assessments Monday through Friday to monitor for changes. Two nurses independently assessed baseline skin tone, and their results were compared to determine the tools reliability. The study found moderate agreement between nurses but could not establish whether the tool detected subtle early skin injuries because no participants developed the necessary changes.
2: Discuss the research question or main problem discussed in the study. A: The main problem addressed in this study was the difficulty of detecting early skin injuries in patients with dark skin tones. Traditional skin assessments rely heavily on visible redness, which may be difficult to identify in darker skin, potentially delaying treatment and allowing pressure injuries to worsen. The researchers wanted to determine whether the modified Robinson- Ho Skin Type Color Bar could help nurses recognize subtle changes in skin pigmentation and whether different nurses could use the tool consistently. The study also highlighted that race and ethnicity are unreliable indicators of skin tone. Overall, the research aimed to improve early skin injury detection and promote more equitable patient care.
Article: Identification of Skin Injuries in Patients With Dark Skin Tones Using a Modified Robinson-Ho Skin Type Color Bar: A Pilot Study
1. Discuss the research questions or main problem discusses in the study.
This study highlights the challenges healthcare staff endure when assessing the beginnings of skin injuries in darker skin patients. Generally, skin assessments encompass visualizing characteristics of color changes in a progressing wound. On darker skin this would be a less obvious finding. The issue with this study was there were limited subjects to assess subtle skin changes as the subjects developed deep tissue injuries.
2. What are the advantages and disadvantages of implementing the article recommendations on your unit and/or hospital?
We as a hospital definitely need to be as vigilant as possible to the notion that anyone is susceptible to pressures injuries and compromised skin integrity. The advantage is to highlight awareness that relying on visualizing the skin is not necessarily the best way to assess skin integrity. We need to also palpate pressures areas and lightly wipe suspicious areas to check for the presence of drainage, blood, secretions, and etc. Being more hands on with assessments is a tool that will enable healthcare providers to better assess skin integrity.
1, How does this research article compare to our practice, policy and/or procedure?
The study is different from our usual practice because we do not routinely use the modified Robinson-Ho Skin Type Color Bar. The study used this tool to compare the patient’s baseline skin tone with later skin changes. However, the study could not show that the color bar was effective for early detection because only two patients developed skin injuries, and their injuries appeared suddenly without subtle skin color changes. However, this study shows that skin assessment can be more difficult in patients with dark skin tones. Redness or purple/maroon discoloration may not be easy to see. Therefore, nurses should not only look for redness but also assess changes in skin temperature, texture, firmness or softness, pain, and changes from the patient’s normal baseline skin tone. This is important because early signs of a pressure injury may be missed in patients with dark skin tones.
2, What are the advantages and disadvantages to the proposed recommendations in the article?
There are several benefits of using the recommendations from this study in our unit. We have many patients who are at high risk for pressure injuries, and we perform skin assessments regularly. This study reminds us that redness may be difficult to see in patients with dark skin tones. Nurses should not only look at skin color but also assess skin temperature, texture, pain, and other changes from the patient’s baseline skin condition. This may help us identify skin injuries earlier and prevent them from getting worse. Another benefit is using a skin tone guide to identify and document the patient’s baseline skin tone. This can help nurses compare skin changes during the hospital stay. Also, the study did not prove that the modified Robinson-Ho Skin Type Color Bar can detect all pressure injuries early. Only two patients developed skin injuries during the study, and both injuries appeared suddenly without subtle skin color changes. Therefore, I think the tool may be helpful for identifying baseline skin tone, but it should be used together with our regular visual and tactile skin assessment, not by itself.
1, How does this research article compare to our practice, policy and/or procedure?
This study is a bit different from how we usually do things because we don't normally use that special Robinson-Ho skin color bar to track changes from a patient's baseline. In the end, the study couldn't really prove if the color bar helps catch injuries early, mostly because only two patients actually got hurt, and their injuries just popped up out of nowhere without any gradual color shifts.
The real eye-opener here is just how hard it is to spot skin damage on patients with darker skin tones, since typical redness or purple and maroon bruising doesn't show up easily. Because of that, nurses can't just rely on a quick visual check for redness. We have to look at the whole picture by feeling for changes in temperature and texture, checking if the skin feels unusually firm or soft, asking about pain, and noting any deviations from the patient's normal skin tone so we don't miss those critical early warning signs of a pressure injury.
2 Discuss the research questions or main problem discusses in the study.
This study underscores the distinct clinical challenges healthcare providers face when evaluating the initial stages of pressure injuries in patients with darker skin tones. Conventional dermatological assessments heavily rely on the visual inspection of erythema and localized color shifts to track wound progression. However, in patients with high melanin levels, these visual indicators are significantly less pronounced and frequently obscured. A notable limitation of this research was its insufficient sample size, which precluded the evaluation of subtle, gradual epidermal color changes, as the few participating subjects rapidly developed acute deep tissue injuries.
Discuss the research question or main problem discussed in the study.
The study examines whether a modified Robinson-Ho Skin Type Color Bar can help nurses identify subtle skin changes and injuries in patients with dark skin tones. Early skin injuries may be difficult to recognize because redness or discoloration may not be easily visible. The study evaluates whether this tool can improve skin assessment and early detection of injury.
Discuss the limitations of the article. A major limitation is the small sample size and the limited number of skin injuries that occurred during the study. The tool was unable to detect the subtle changes in the two patients who developed deep tissue pressure injuries. Larger studies with more diverse patients and different types of skin injuries are needed to determine the tool’s effectiveness.
Discuss the research question or main problem discussed in the study:
The study focuses on the challenges and difficulty of detecting early skin injuries in patients with dark skin tones. The study addresses that the subtle change in color may be difficult in recognizing appropriate skin assessment which can then lead to worsening pressure injuries. The study evaluated whether the modified Robinson-Ho skin type color bar help nurses to use as a tool to identify skin early changes as a method of skin assessment.
Discuss the method used by the author in the study:
A pilot study was performed in a surgical intensive care unit (SICU). Adult patients' who did not have existing skin pressure injuries with dark skin tones were included. The modified Robinson-Ho Skin type color bar was also used to establish the patients' baseline skin tone and then observed for skin injury development. The study was conducted in about two months.
What are the advantages and disadvantage of implementing the article recommendations on your unit and/or hospital?
The advantages are that there are the useful clinical pearls in this article, which we would adopt to our skin protocol if we will develop the bundle to improve on dark skin toned patients. For example, our standard skin assessment should be pared with tactile one, such as texture, temperature and sensation. That way, we can detect 'boggy feeling to touch, and pain resulting in identifying the skin injuries even without skin break down. In order to notice skin injury among the mixed-race patients, we should rely on visual inspection, instead of race/ethnicity. The article also highlights importance of standardization of daily assessments for consistent skin assessment, such as the source of light or skin prep. Our skin prep is consistent using specific products, which are determined by our WOCN thankfully, but our source of light is often not available due to poor maintenance.
The biggest disadvantage is that their modified Robinson-Ho Skin Type Color Bar was not useful to detect subtle changes of skin injury. Without a skin tone-based tool, our skin assessment would be very difficult and confusing, which reduces consistency of assessment and rises skin injury. We need not only a good amount of training, but also annual follow-up education to achieve and keep the good assessment skills, which would be time-consuming requiring patience and can be costly. As for the standardization for daily assessment, buying and maintaining the source of light efficient can be problem together with its cost since a flashlight, our source of light is supposed to be available in each room of ICU, but it's not always useful because we find the battery often gets low or dead because everyone is responsible, which is ended no one to maintain it.
Discuss the research question or main problem discussed in the study?
I believe the main problem in this article is that their modified Robinson-Ho Skin Type Color Bar did not empower the routine visual/tactile skin assessment to detect early signs of skin injury in patient with dark skin tones even though they proved that this objective tool was reliable to use producing the same result among the clinicians. They concluded this skin tone-based guide was useless since the 2 wounds were developed without the first subtle sign. The researcher points out the guide cannot work to catch the first sign due to the wide variations of skin tone in their heels and in their baseline skin tone in the sacrococcygeal region. In addition to these problems, the pigmentation can be different due to leg position or clinical condition, such as hypo-perfusion or edema. In our ICU, our critical patients often show skin mottling due to hypo-perfusion, edema due to circulatory problem and ecchymosis due to coagulopathy, our assessment of the skin pigmentation in dark skin patients is complicated and very difficult to catch the early sign of skin injury. As the article mentions, I hope we would adopt the devices that able to spot the early change of skin tone near future even though there might be a budget problem. In order to reduce the incidents and deterioration of skin injury among the dark skin population, visual/tactile assessment alone can be labored and time-consuming resulting increased risk of lack of consistency in assessment among the clinicians. In Skin Symposium, somebody mentioned about herald AI assisted devises for skin assessment in Keck. Personally I am very curious how those devices identify the first signs of skin injury since the article says these kind of devices are not influenced by pigmentation. I do agree that our assessment should not been taken over by the devices including AI, but their objective eye can be very helpful for our clinical decisions.
The researchers planned to include 44 patients, but the final study included 42 patients. Most of the participants were Black, and everyone included had a darker skin tone based on the tool being studied. Since this was a pilot study, the smaller sample helped the researchers test whether the skin tone tool could work before doing a larger study. However, using only 42 patients makes it harder to know if the same results would be seen in a larger group of patients.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
One limitation was the small sample size of only 42 patients from one hospital unit. The patients during the study were also less critically ill than the patients normally treated on that unit, so the results may not fully represent the usual patient population. Another limitation was that the skin tone tool could not always account for differences in skin color around areas such as the heels and sacrum. The study also did not include patients who did not speak English because translation services were not funded, which limited the types of patients who could participate.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias There were several limitations in this pilot study related to the overall sample size and design. The pilot study used a modified Robinson-Ho skin type color bar; however, they did not realize that the tool would not be able to determine the skin tone changes in the areas on or by the sacral coccyx and the heels. The research team realized during the study that there was a wide range of skin tone variation in those areas that the skin color bar could not determine whether a pressure injury was forming. The sample population was 42 participants, but among the participants on the unit, many were less critically ill than what is considered normal for the acute and critical care unit during the study period. Due to this finding, the findings may not have correctly portrayed what is typical for this unit. The research team also mentioned that they did not budget for interpretation services, so non-English speaking patients were excluded.
Discuss the sample size used in the study. In this pilot study to identify pressure injuries utilizing a modified Robinson-Ho skin type color bar, the ideal goal sample size was 44 participants at large urban medical center in an acute and critical care unit. The number was determined on the research team's previous past experience with the patient population and there was already feasibility established. While the study was being conducted, there was an updated total sample size of 42 due to sample saturation. The research team discussed and agreed that the sample saturation had been reached so no further recruitment was needed.
1) Discuss the research question or main problem discussed in the study?
The study examines how fat-tissue thickness affects muscle stress and strain in people with transfemoral amputations and their risk of deep tissue injury (DTI) under the prosthetic socket. Researchers used 3-D models with different fat-layer thicknesses and simulated socket use and standing. They compared muscle compression and strain with known cell-death thresholds to identify which fat levels may increase the risk of hidden, deep pressure injuries.
2) what are the advantages and disadvantages of implementing the article recommendations on your unit and/or hospital?
On a rehab unit this would give you a quick flag for very lean residual limbs—fat under about 6 mm or body-fat under 10%—so you could watch donning more closely and follow those patients tighter. The problem is it comes from one computer model of one stump, and whole-body BMI still doesn’t tell you what’s actually sitting over the cut femur. You also can’t just add fat on command, measuring thickness properly takes ultrasound and time, and it’s easy to chase the number while missing a poorly fitting socket.
1) What are the advantages and disadvantages to the proposed recommendations in the article?
The paper basically says hospitals should stop using race as a stand-in for skin tone, instead use a simple color-bar tool to record a patient’s baseline, build that into the charting system nurses already use, and look at gadgets that can pick up early tissue damage even when pigment hides it. That’s useful because it gives a more objective starting point, nurses could apply the bar without extra training and still mostly agreed with each other, and it might help catch problems before they become full-thickness wounds. The catch is that the color bar didn’t actually help with the two injuries that showed up in the study—they appeared suddenly instead of as faint color shifts—and it struggles with the natural patchiness on heels and the sacrum, changing light, and how sick patients’ skin can look from poor perfusion. The tech ideas also cost money and haven’t been proven at scale yet, especially in a small pilot where almost no early injuries even occurred.
2). Discuss the sample size used in the study.
They set out to enroll 44 patients because that felt doable from their earlier quality-improvement work on the same unit, and they ended up with 42 after a full year when they decided they’d hit saturation. That’s a typical pilot-study size, but it’s still small—and the real problem is that only two people actually developed a wound, neither of which showed the subtle color shift the tool was supposed to catch. So they never really got to test the main question, and the sample also happened to be less critically ill than the unit usually sees, which may have kept injury rates even lower.
Discuss the research question or main problem discussed in the study. The main problem is that beginning skin injuries like stage 1 can be missed in patients with darker skin because redness and discoloration don't present in the same way. When pressure injuries are not caught early, they will continue breaking down until obvious breakdown occurs. The researchers wanted to see if a modified Robinson-Ho skin type color bar used during skin assessment would help nurses notice early changes. The second goal was to find out if two nurses using the tool would pick the same skin tone for the same patient.
Discuss the sample size used in the study. The researchers used 42 patients for a year to collect data. All of the patients were adults with darker skin tones and no noted skin injuries at the beginning of the study. This study took place in one surgical ICU unit. The group was small and only two patients ended up developing skin injuries, therefore the researchers could not determine if the tool helped catch injuries early.
Describe the method used by the author of the study.
The authors used a prospective observational pilot study involving 42 adult patients with dark skin tones. Researchers used a modified Robinson-Ho Skin Type Color Bar to assess and document the patients’ baseline skin color, and monitored them for changes that could indicate skin injury. Multiple clinicians performed assessments to determine how consistently the tool could be used.
The study had a final sample size of 42 adult patients with dark skin tones. The researchers originally planned for 44 participants but stopped at 42 after reaching sample saturation. Because it was a small pilot study and only two participants developed skin injuries, the findings were limited in determining how effective the color bar was at detecting early skin changes.
- The study enrolled 42 adults, just short of a goal of 44 that the authors set based on "prior experience and feasibility" rather than a power calculation or any estimate of how many injuries to expect. For a pilot study, a small sample is acceptable, since the goal is to test feasibility and refine methods, but the size matters differently for each aim. For the primary aim, detecting early skin tone change from injury, what counts is the number of injury events, not the number of patients, and only two of the 42 participants developed a wound. Both were sudden and obvious, so the aim could not be evaluated at all, and the authors admit the low sample size prevented them from learning whether the tool would detect subtle changes in other wound types.
2) Discuss the research question or main problem discussed in the study:
- The study addresses a specific equity problem in pressure injury care: early skin injuries are harder to detect in patients with dark skin tones, and missed early detection lets wounds progress to more severe, costly, and deadly stages. In lighter skin, the first warning sign is usually redness that may or may not blanch under pressure. In darker skin, eumelanin can mask that redness and the purple or maroon discoloration that typically follows, so an injury may show up instead as a subtle hyperpigmented or hypopigmented patch, a boggy or firm feel, temperature change, or pain. The authors point to disparities in the literature, including higher incidence, severity, and mortality from pressure injuries in Black patients, and to two clusters of preventable full-thickness wounds on their own unit in patients with dark skin, as evidence that current visual and tactile assessment is missing these early changes. Existing tools are also imperfect: the Fitzpatrick scale was built around sun reactivity in lighter-skinned people, the Munsell chart includes many colors that don't resemble human skin, and race or ethnicity, which is often used as a stand-in, is self-reported and does not reliably reflect actual skin tone. From this, the study poses two questions. The first, which is the primary one, is whether adding a modified version of the Robinson-Ho Skin Type Color Bar (limited to its darker rows and used alongside the usual visual and tactile exam) can detect subtle changes in skin tone at the sacrum and heels that signal early injury in patients with dark skin. The second is whether the tool is reliable between raters, meaning that two nurses independently assessing the same patient would choose the same swatch. The authors also carry a related hypothesis that an objective, tone-based scale would categorize patients' risk better than race or ethnicity does. The underlying goal, framed through Levine's Principle of Conservation of Structural Integrity, is to preserve skin integrity by catching damage early enough to intervene. It is worth noting that the paper answers the second question far better than the first: the primary question could not be evaluated because no one developed a subtle change, so the study ends up speaking mainly to reliability and to the weakness of race and ethnicity as proxies for skin tone.
1. Discuss the research question or main problem discussed in the study.
The main problem discussed in this study was the difficulty of identifying early skin injuries in patients with dark skin tones. Early signs of pressure injuries, such as redness or changes in skin color, can be harder to see on darker skin. If these changes are missed, the injury may become worse before it is recognized and treated. The researchers wanted to determine whether the modified Robinson-Ho Skin Type Color Bar, when used along with the usual visual and tactile skin assessment, could help nurses recognize subtle skin tone changes that may indicate an early skin injury. They also wanted to determine whether different nurses could use the tool and obtain similar results. Although the study did not show that the tool was effective at detecting early skin injuries, it did show moderate reliability between nurses when identifying a patient's baseline skin tone.
2. Discuss the limitations of the article: limited sample size, design flaws, and/or author bias. One limitation of this study was the small sample size. The researchers planned to include 44 patients but ended with only 42 participants. Two patients developed a skin injury, and neither injury showed the subtle skin color changes the researchers were hoping to study. As a result, the researchers could not determine whether the modified Robinson-Ho Skin Type Color Bar could identify early skin injuries in patients with dark skin tones. The design limitation included only one acute and critical care unit, and patients during the study period were less critically ill than those normally treated on that unit. The researchers also found that skin tone naturally varied in areas such as the heels and sacrococcygeal area, making the color tool more difficult to use. In addition, the authors excluded non-English-speaking patients because translation and interpretation services were not available. These limitations make it harder to apply the results to a larger and more diverse patient population. The article provides clear evidence of significant author bias because the researchers openly discussed the study's weaknesses and limitations.
Describe the method used by the author of the study.
• Design: Prospective, observational cohort study. • Setting: A surgical intensive care / acute care unit within an urban, academic hospital. • Participants: Hospitalized adults (≥ 18 years old) who entered the unit with no pre-existing skin injuries but possessed a confirmed dark skin tone baseline.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The most significant limitation of the study is the extreme shortage of clinical events (wounds) to evaluate. Statistical Power: Because only two injuries occurred, the authors lacked the sample breadth required to definitively test if the tool could identify slow-evolving, subtle skin changes. Two data points are insufficient to claim a tool is globally "ineffective" for all early-stage injuries rather than just the specific acute presentations witnessed. Potential Author and Literature Bias: • Confirmation Trap Regarding Race Data: The authors explicitly highlight that self-reported race or ethnicity is not a reliable proxy for skin tone. However, in structuring a tool designed specifically around visual charts, the research remains tethered to a paradigm that tries to fix visual evaluation rather than pivoting toward objective, non-visual technological assessments (like sub-epidermal moisture scanners). • The "Pilot Study" Mandate: As a pilot study, it is intentionally designed to explore feasibility rather than establish definitive clinical protocol. A structural bias exists toward finding any baseline utility—which explains why, despite failing its primary aim (detecting injury), the study frames the moderate inter-rater reliability as a major victory for baseline skin tone tracking
1) What are the advantages & disadvantages to the proposed recommendations in the article?
ReplyDeleteThe article recommends adopting a modified Robinson-Ho Skin Type Color Bar as an objective, standardized tool for baseline skin tone assessment in patients with dark skin tones. This is proposed to complement standard visual/tactile skin assessments, improve early detection of skin injuries (especially pressure injuries), enhance documentation, and reduce over-reliance on subjective race or ethnicity categories.
Advantages:
• Promotes health equity by helping clinicians better identify subtle skin changes (e.g., purple/maroon discoloration or hyperpigmentation) that are often missed in darker skin tones.
• Provides a reliable method for documenting baseline skin tone with moderate inter-rater reliability, supporting consistent tracking over time.
• Supports staff education, training, and integration into electronic health records or mobile documentation systems.
• Low-cost, non-invasive, and easy to combine with existing practices like photography and proper lighting/moisturizing techniques.
Disadvantages:
• In this pilot study, the tool was not effective at detecting subtle early skin injuries due to sudden-onset wounds and pigmentation masking effects.
• Practical challenges include variation in skin tone across body sites (e.g., sacrococcygeal area vs. other regions), lighting conditions, patient positioning, and added workflow steps.
• Limited generalizability due to small sample size, critical care setting, and need for staff training/resources.
2) Describe the method used by the author of the study.
The authors conducted a prospective, observational cohort pilot study in a surgical intensive care/acute care unit (SICU/ACU) at NYU Langone Health.
Key elements:
• Sample: 42 adult participants (≥18 years old, mean age ~50) with confirmed dark skin tones based on the modified Robinson-Ho scale and no existing skin injury at enrollment. Mostly Black (76%), with exclusions for cognitive impairment, end-of-life care, etc.
• Tool: A modified version of the Robinson-Ho Skin Type Color Bar focusing on darker shades (rows 3–6), with added numbering for documentation, a centimeter ruler, and fields for patient details, date, and location.
• Procedures: Baseline assessments of high-risk areas (sacrococcygeal region and heels) using the color bar tool plus standard visual/tactile evaluation and photography by two independent raters. Daily assessments (Monday–Friday) followed the same sequence until discharge or skin injury (up to 3 months). Skin was prepared with cleansing and moisturizing under consistent lighting.
• Analysis: Descriptive statistics for demographics; Fleiss Kappa for inter-rater reliability on baseline normal skin; data analyzed in SPSS v29.
• Design: Aimed to test the tool’s ability to detect injury-related skin tone changes and inter-rater reliability. IRB-exempt status with informed consent obtained.
Describe the method used by the author of the study.
ReplyDeleteThe researchers conducted a prospective observational cohort pilot study over a 12-month period in a surgical intensive care and acute care unit at an urban academic hospital. Adult patients with dark skin tones who did not already have a skin injury were enrolled and received daily skin assessments using both the modified Robinson-Ho Skin Type Color Bar and the standard visual and tactile skin assessment. Baseline skin tone measurements and photographs of the sacrococcygeal area and heels were collected, and participants were monitored until discharge or until a skin injury developed. To evaluate the reliability of the tool, both a research nurse and a clinical nurse independently assessed each participant's baseline skin tone, and the researchers used statistical analysis to measure agreement between raters.
Discuss the sample size used in the study.
The pilot study included a final sample of 42 adult patients with dark skin tones. The researchers originally planned to recruit 44 participants, but data collection ended after one year because they determined that sample saturation had been reached. Participants were recruited from a surgical intensive care and acute care unit and had to be at least 18 years old, have no existing skin injuries, and meet the study's criteria for dark skin tone using the modified Robinson-Ho Skin Type Color Bar. Although the sample size was relatively small, it was considered appropriate for a pilot study designed to evaluate the feasibility and reliability of the assessment tool before conducting larger studies.
Discuss the sample size used in the study.
ReplyDeleteThe sample size for this pilot study was 44 patients. This
number was based on the team’s prior experience and feasibility
for conducting work with this population. The pilot study
achieved a total sample size of 42, because of sample saturation.
At 1 calendar year since the beginning of data collection, the study
team agreed that saturation had been reached. The pilot study sample consisted of 42 participants with a mean age of 50.31. OF the total participants, 57% were male, 76% identified themselves
as Black, and 67% identified as not of Spanish/Hispanic origin.
Discuss the research question or main problem discussed in the study?
The objective of this study was to determine whether a modified version of the Robinson-Ho Skin Type Color Bar would identify early, subtle skin tone variations in patients with dark skin tones because of injury. They also were trying to determine if the tool was reliable between clinicians. The purpose of this research was to determine whether the addition of an objective, noninvasive skin tone measuring guide to the standard visual/tactile skin assessment process would assist in identifying warning signs of a skin injury.
1. Discuss the research question or main problem discussed in the study?
ReplyDeleteThe study looks at the difficulty of identifying early skin injuries in people with dark skin tones. Changes in skin color are often harder to see, which can delay treatment and allow the injury to become more serious. The researchers wanted to find out if the modified Robinson Ho Skin Type Color Bar could help healthcare professionals detect these early skin changes more accurately and consistently.
2. What are the advantages and disadvantages to the proposed recommendations in the article?
Advantages
The recommendations can help healthcare professionals identify skin injuries earlier in patients with dark skin tones. Earlier detection allows treatment to begin sooner and may prevent the injury from becoming more serious. The color bar also gives healthcare professionals a simple and more consistent way to check for changes in skin color, which can improve patient care.
Disadvantages
The study was done with a small group of participants, so the results may not apply to everyone. Healthcare professionals may also need training to use the color bar correctly. More studies are needed to make sure the tool works well in different hospitals and with a larger number of patients.
1. Discuss the limitations of the article; limited sample size; design; flaws and/or author bias?
ReplyDelete* The tool used in this article has a flaw because it was unable to account for the different variation in skin tones especially on the sacrococcygeal area and heels. The modified Robinson-Ho Skin Type Color Bar tool was unable to include the patient's clinical conditions, where skin tone changes were not noted because of critical illness. The study also did not have funding for translation and interpreter services therefore the study was not able to include non-English patient.
2. Discuss the research question or main problem discussed in the study?
* The research study utilized the modified Robinson-Ho Skin Type Color Bar to determine if it could assist in identifying warning signs of a skin injury. Robinson-Ho Skin Type Color Bar was created to accomodate possible skin tone options ranging from light to dark skin tones. Clinicians used this skin tone assessment for determining a patient's risk for misidentification and developing a wound because of pigmentation. The study's use of modified Robinson-Ho Skin Type Color Bar in addition to visual/tactile skin assessment can help in patients with dark skin tones. The study showed that race and ethnicity are not a reliable indicators of skin tones, but the use of modified Robinson-Ho Skin Type Color Bar in this study helped identify early skin injuries in patients with dark skin tones.
1. What are the advantages and disadvantages to the proposed recommendations in the article?
ReplyDeleteThe article recommends using an objective skin tone assessment tool instead of relying on race or ethnicity to identify patients with dark skin tones who may be at risk for delayed skin injury detection. One advantage is that the tool provided a reliable way for different clinicians to identify baseline skin tone and could help improve consistency in assessments. Another advantage is that it promotes more equitable care for patients with dark skin tones. However, the study found that the tool was not effective at detecting early subtle skin changes that signaled injury, limiting its usefulness. The authors also suggested that newer technologies may be more effective, but these could be more expensive and harder for hospitals to implement.
2. Discuss the research question or main problem discussed in the study.
The main research question was whether a modified Robinson-Ho Skin Type Color Bar could help clinicians detect early skin injuries in patients with dark skin tones and whether different clinicians could use the tool consistently. The study focused on the problem that skin injuries are often harder to recognize in darker skin, which can delay treatment and lead to worse outcomes. Researchers found that the tool was reliable for identifying baseline skin tone, but it did not successfully detect early skin injury changes in this pilot study. The findings also showed that race and ethnicity are not accurate ways to determine skin tone. Overall, the study highlights the need for better methods to identify skin injuries early in patients with dark skin tones.
1. Discuss the research question or main problem discussed in the study?
ReplyDeleteThe primary issue addressed in this study is the continuous difference in the detection and prevention of pressure injuries (PIs) among individuals with darker skin tones. Evidence suggests that individuals with dark skin had a higher incidence, severity, and death rate from pressure injuries, which may be due to the difficulty of detecting early-stage pressure injuries using typical visual evaluation methods. Current assessment techniques frequently focus on race or ethnicity rather than objective measures of skin tone, which can result in delayed detection and treatment. The study sought to see if adding an objective, noninvasive skin tone measurement guide to the standard visual and tactile skin assessment could improve the early detection of pressure injury warning signs and promote more equitable skin assessments across diverse skin tones.
2. Describe the method used by the author of the study
This pilot study used a prospective observational cohort design with inter-rater reliability testing to determine the efficacy of an objective skin tone assessment tool for detecting early pressure injury early warning signs in patients with dark skin tones. The study was conducted over a 12-month period in an acute and critical care unit of a big metropolitan academic medical center and was exempt from the institutional review board (IRB). Adult patients (18 years and older) hospitalized to the surgical intensive care unit (SICU) or acute care unit (ACU) with proven dark skin tones, as established by the modified Robinson-Ho Skin Type Color Bar, were eligible to participate. Patients undergoing hospice or end-of-life care, those with prior skin injuries, deceased organ donors, and those with cognitive impairment were eliminated. All subjects provided informed consent before to registration. The prospective design enabled researchers to track changes in each patient's baseline skin tone and determine whether adding an objective skin tone assessment improved the early detection of pressure injuries in individuals with darker skin tones.

Describe the method used by the author of the study:
ReplyDeleteThe design method of this study is a prospective, observational cohort study. Over 12 months, the study sought to identify patients with dark skin tones and then observed how skin toned varied with skin injuries within that population of patients. A prospective method was chosen in order to accurately differentiate between injured and uninjured patients with darker skin tones. This was an important decision, because the literature supported the idea that dark skinned patients typically have more severe wounds at the time of reporting because early identification is often missed in this population.
Discuss the limitations of the article:
The study was unable to account for the wide variation of skin tones on the sacrococcygeal area and heels of patients included in the study. The study utilized a modified version of the Robinson-Go Skin Type Color Bar, but this tool was not vast enough to represent all patients, and also did not accommodate for changes in clinical conditions that affected the patient’s skin due due to critical illness (perfusion, etc). The patients studied during this 12-month period were less clinically complex than the unit typically cares for, so the results of the study may not be reflective of normal operations. Another factor was the exclusion of non-English speaking patients within the study due to translation service cost, which excluded a large portion of vulnerable, melanated individuals.
Discuss the research question or main problem discussed in the study?
ReplyDeleteThe research question in this study is to see whether a modified version of the Robinson-Ho Skin Type Color Bar would assist nurses in identifying skin tone variations in patients with dark skin tones because of injury. A darker skin tone can make identifying pressure and skin injuries more difficult to identify early on. The lack of identification can delay treatment or preventative measures for those with darker skin tones in this patient population.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias
This study had some limitations, such as the inability to accommodate changes in clinical conditions where skin tone changes were noted, due to perfusion or hypoxia or other conditions that may affect skin tone changes. The conductors of this study were unable to use translation and interpretation services due to funding, therefore were unable to include any non-English speaking participants. Further limiting the study, the unit population was less critically ill than the usual population of patients admitted on the unit.
Discuss the research question or main problem discussed in the study.
ReplyDeleteThe main problem addressed in this study is the critical lack of equitable resources and clinical knowledge for identifying skin injuries in patients with dark skin tones. I have observed that early warning signs of pressure injuries such as non-blanchable erythema are often missed because darker pigmentation can mask the typical redness clinicians are trained to look for. This often results in delayed detection that leads to more severe wounds, and ultimately contributes to higher rates of morbidity, mortality, and treatment. The main question focuses on whether integrating an objective modified version of the Robinson-Ho Skin Type Color Bar can help clinicians identify early subtle skin tone variations indicative of injury over high risk areas like the heels and sacrococcygeal region. By evaluating the tool's inter-rater reliability among clinical staff, they intended to introduce a more objective marker for skin tone assessment instead of subjective and often unreliable categories such as self reported race or ethnicity.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The most significant flaw is the small sample size of only 42 participants drawn from a single acute and critical care unit at one urban academic medical center. The limited sample size restricts makes it harder to generalize the findings to other patient populations or clinical settings especially as that unit’s patient population was less critically ill than usual during the study period. Another major design limitation emerged as no patients developed the early, subtle skin tone changes the tool was supposed to detect and the only two wounds that occurred were already highly visible. The tool also struggled to account for natural skin tone variations on the heels and sacrococcygeal area, and didn’t adequately accommodate other clinical factors like edema or mottling which further limited its practical effectiveness. Finally, excluding non English speaking patients due to a lack of funding for translators plus the absence of a formal cost benefit analysis represent missed opportunities to fully assess the tool’s usefulness in a broader clinical setting.
ReplyDeleteDiscuss the research question or main problem discussed in the study.
The main problem discussed in this study was to determine if a modified version of the Robinson-Ho Skin Type Color Bar could identify subtle tone variation in patients with dark skin tones and if this tool was reliable between users. Skin tone plays a key role in proper skin assessment. The article notes that there was a higher incidence of advanced PIs in Black patients compared to White patients, likely because there was a missed identification of Stage 1 PI in patients with darker skin tones. One of our assessments, looking for non-blanching redness, can appear differently on dark skin tones.
Discuss the limitations of the article.
One limitation of this article was its lack of funding, which notably, did not allow the researchers to have translation and interpretation services. This caused the study to exclude non-English-speaking patients in their study. This is a larger oversight as there may have been many patients with dark skin tones that could have been included, but were not, simply because they did not speak English. In order to help address disparities in our healthcare system, special care should be taken with minority populations. While I appreciate this study in specifically studying patients with darker skin tones, another often overlooked minority population includes those who do not speak English. If they were to do another study like this, I hope they could get the funding for translation services to increase their study population to include non-English-speaking patients.
1. Describe the method used by the author of the study.
ReplyDelete- The study used a prospective, observational cohort design to evaluate wether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify subtle skin-color changes associated with skin injury in patients with dark skin tones and wether different clinicians could use the tool consistently.
2. Discuss the limitations of this article.
- A major limitation of the study was the limited number of patients who developed skin injuries during the observation period. Only twi injuries occurred and neither demonstrated the subtle skin-color changes that the modified Robinson-Ho Color Bar was designed to identify. Consequently, the study could not establish the tool’s effectiveness for early detection of skin injury. In addition, the study was conducted in a single urban academic hospital which limits generalizability to other patient populations and healthcare settings.
1. What are the main findings of the study?
ReplyDeleteThe study found that the modified Robinson-Ho Skin Type Color Bar was not very effective at detecting early skin injuries in patients with dark skin tones. The researchers did find that the tool was reliable when different nurses used it to identify a patient’s normal skin tone. This shows that skin color alone may not be enough to identify an injury early. Nurses should also look at other changes such as skin texture, temperature, swelling, and pain.
2. How can the findings of this study be applied to patient care?
This study shows why nurses should use more than just skin color when checking patients with dark skin tones for injuries. Redness or other color changes can be harder to see, which could cause an injury to be missed. Nurses can use touch and look for changes in temperature, texture, pain, or swelling along with visual assessment. More complete skin assessments may help nurses identify pressure injuries earlier and prevent them from becoming more serious.
2. Identification of Skin Injuries in Patients With Dark Skin Tones
ReplyDeleteHow does this research article compare to our practice, policy and/or procedure?
This study addresses a gap that is highly relevant to skin-integrity practice: early skin injury can be harder to recognize when clinicians rely mainly on visible redness. The modified Robinson-Ho Skin Type Color Bar provided a more objective way to document baseline skin tone and showed moderate agreement between clinicians. That approach is consistent with a skin-integrity program focused on early identification and prevention, although the study did not prove that the tool detects early injury reliably (Savage et al., 2026; Providence, 2026a).
What are the advantages and disadvantages to the proposed recommendations in the article?
Advantages. The strongest potential benefit is more consistent baseline documentation of skin tone. It may also remind nurses not to use race or ethnicity as a substitute for an actual skin-tone assessment. A standardized baseline could make later changes easier to recognize and communicate between clinicians.
Disadvantages. The tool adds another assessment step, and the pilot study did not demonstrate that it could identify subtle early injury changes. Training would be needed to use it consistently, and relying on the color bar alone could be unsafe because pressure-injury assessment also requires tactile findings, temperature, pain, tissue consistency, and other clinical observations.
Describe the method used by the author(s) of the study.
The authors used a prospective observational cohort design in a surgical intensive care/acute care unit at an urban academic hospital. Adults with dark skin tone and no skin injury at enrollment were followed using the modified Robinson-Ho Skin Type Color Bar (Savage et al., 2026).
Discuss the research question or main problem discussed in the study.
The study asked whether the modified color bar could identify early subtle skin-tone changes caused by injury in patients with dark skin tones and whether different clinicians could use the tool reliably.
Discuss the sample size used in the study.
The pilot enrolled 20 patients. Only two developed a skin injury during the study, and those injuries did not present as the subtle color changes the tool was intended to detect (Savage et al., 2026).
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The very small sample is the main limitation. Only two patients developed skin injuries, so the investigators could not adequately test the tool's ability to detect subtle early changes. The study was also performed in a single clinical setting. These factors limit generalizability and make the findings preliminary.

DeleteThe study used a prospective observational cohort design over a 12-month period to evaluate whether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify skin color changes associated with early skin breakdown in patients with dark skin tones. Researchers identified patients with darker skin pigmentation and then monitored them over time to observe how skin tone changed when injuries developed versus patients who remained injury free. The study also examined whether different clinicians could use the modified color bar consistently during skin assessments.
2. Discuss the limitations of the article.
One major limitation was the small number of skin injuries observed during the 12-month study period. Another limitation was the exclusion of non-English speaking patients. This is not representative of the patient population found at St. Joseph. This exclusion reduced the diversity of the sample.

- The study used a prospective, observational cohort design to evaluate wether a modified Robinson-Ho Skin Type Color Bar could help clinicians identify subtle skin-color changes associated with skin injury in patients with dark skin tones and wether different clinicians could use the tool consistently. The methodology was appropriate for an early pilot study because the researchers were testing a relatively new approach in a real clinical environment. The prospective design allowed them to establish patient’s baseline skin tone before any injury occurred and then observe what happened overtime.

1. Discuss the research question or main problem discussed in the study.
ReplyDelete- The main problem discussed in this study is the difficulty of identifying early skin injuries, including pressure injuries, in patients with darker skin tones. Subtle changes in skin color can be harder to recognize in darkly pigmented skin, which may lead to delayed identification and treatment of skin damage. The researchers examined whether a modified Robinson-Ho Skin Type Color Bar could provide a more objective way for clinicians to identify a patient's baseline skin tone and recognize subtle changes that may indicate injury. They also wanted to determine whether different clinicians could use the tool consistently. Improving early recognition of skin changes is important for bedside nurses because earlier identification can allow preventive interventions to be started before the injury progresses.
2. What are the advantages and disadvantages to the proposed recommendations in the article?
- One advantage of the recommendation is that the modified Robinson-Ho Skin Type Color Bar could help nurses identify and document a patient's baseline skin tone more objectively. This may make skin assessments more consistent between nurses and help reduce the risk of missing early skin changes in patients with darker skin tones. It could also increase staff awareness that redness may not be as visible in darker skin and that other changes, such as differences in temperature, texture, firmness, pain, or discoloration, should also be assessed. A disadvantage is that the study did not provide enough evidence that the tool can reliably detect early skin injuries, and the injuries did not show the subtle color changes the researchers were looking for. The tool would also require staff education, practice, and additional assessment time. It should be used as one part of a complete skin assessment rather than relied upon alone. More research with larger and more diverse patient populations is needed before it can be adopted as a standard tool.
1. Describe the method used by the author of the study.
ReplyDeleteThe method used by the authors in this study was done over a 12 month period. The objective was to identify patients with dark skin tones and observe how skin tone varied with skin injuries. The setting was an acute and critical care unit within a large urban hospital. The study utilized the modified Robinson-Ho skin type color bar.
2. Discuss the sample size used in the study.
The goal sample size for this study was 44 patients. However, the pilot study achieved a total sample size of 42 patients due to sample saturation. The study participants were adults age 18 years and older who remained in the unit of the study during that duration. The exclusion criteria was end of life or hospice, pre-existing skin injury or had cognitive impairment.
Q: Discuss the research question or main problem discussed in the study.
ReplyDeleteA: The main research question was had 2 parts. 1) Whether a modified Robinson-Ho Skin Type Color Bar could help clinicians detect early skin injuries in patients with dark skin tones. 2) Whether the modified tool could be used by different clinicians to make objective assessments. The problem being that the early signs of skin injuries are often harder to recognize in darker skin, resulting in delays in treatment and poorer outcomes. The first aim was unsuccessful because there were not enough individuals who developed subtle skin tone differences in the early stages of injury. The second aim was modestly successful and showed some agreement between users.
Q: Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
A: The primary limitation was the small sample size (42) and that they were taken from a single unit at one urban medical center. This sample size was simply not large enough to accommodate all the mitigating factors that prevented a truly objective study. Environmental factors, socio-economic factors, cultural differences, etc. were not able to be studied or accounted for in such a small sample. There is simply too great a variation in skin tones (from person to person and within the same body) to be able to evaluate patients with darker skin objectively, using one limited tool. Pre-existing and co-existing medical conditions that affect skin tone were the second most limiting factor. Caregivers struggled to use a limited tool when considering complicated clinical factors that affect skin tone, like edema, infection, perfusion or circulatory problems like PAD, and diabetes.
Discuss the research question or main problem discussed in the study?
ReplyDeleteThe main problem discussed in the study is that early skin injuries like developing pressure injuries can be difficult to recognized in patients with darker skin tones. This study is aimed to determine if a modified version of the Robinson-Ho skin type color bar could be used to detect early skin changes on patients with darker skin tones. Skin assessment relies heavily on the visual assessment of the bedside nurse. Developing pressure injuries star with changes to the skin like new redness, however skin color change may be more subtle on darker skin tones and therefore may result in delayed recognition.
Discuss the sample size used in the study.
This study took place in a surgical ICU and included all the adult patients with dark skin tones on that unit that did not initially have a skin pressure injury. The total number of participants was 42, during this study only a small number of participants developed skin injuries, two patients is a small number to gather data from. Therefore, the study could not adequately assess if the use of the Robinson-ho skin type color bar was an appropriate tool to detect subtle skin changes. The tool that was being used could not account for the wide variation of skin tones/pigmentation. One challenge that was mentioned in the study was when using the skin tone rules to assess the sacrococcygeal area, they saw that many patients had different skin tones that deviated from their baseline skin tone.
Q. Discuss the research question or main problem discussed in the study?
ReplyDeleteA. Skin assessment is important nursing skill each nurses need to develop. Every patient is different thus dark skin color may be true to be challenging in some patients combined with other factors.
This study seeks to know if using the modified Robinson- Ho Skin type color bar can help in detection of pressure skin injuries. With this tool, and keen eye and touch will assist in detection and thus preventing pressure injuries.
In previous studies, patients with dark skin tones have an increased incidence and severity of pressure injuries and increased risk of mortality from these injuries.
Past studies between Black and Hispanic showed increased development of pressure injuries than White participants. Nursing home residents that are Black had higher incidence of Stage 2,3,4 pressure injury than White residents. In acute and outpatient setting, Black patients have higher longer stay and expenses related to pressure injury than non-black patients.
Q. Discuss the sample size used in the study.
A. The goal sample for this study is 44 patients but only 42 patients were used due to sample saturation. The study is done one whole calendar year. The setting for this study is in an acute critical care unit. Patients in critical care have greater chances of developing pressure injuries. Patient needs to be 18 years old and above who remained in the unit during the time of pilot study. The enrolled subjects also had a confirmed
dark skin tone category based on their skin matching any of the
tones on the modified Robinson-Ho Skin Type Color Bar.
Patients were not included if they were (1) considered
hospice, end-of-life, comfort care or deceased donor, (2) had a
pre-existing skin injury, or (3) had cognitive impairment because
of a disease process such as from a form of dementia.
1. Discuss the research question or main problem discussed in the study.
ReplyDeleteThis study focused on finding skin injuries early in patients with darker skin tones. Skin changes can be harder to notice on darker skin, especially when looking for early signs such as changes in color. The researchers wanted to see if using a skin color tool along with the regular skin assessment could help nurses recognize these changes earlier. They also wanted to see if different nurses could use the tool and get similar results when assessing a patient’s skin tone.
2. Discuss the sample size used in the study.
The study included 42 adult patients with darker skin tones who were being cared for in an acute or critical care unit. The researchers originally planned to include 44 patients but completed the study with 42. During the study, only two patients developed skin injuries, and neither showed the subtle early skin changes the researchers were looking for. Because there were so few skin injuries, it was difficult to fully determine how effective the tool was at identifying early changes.
1.Discuss the research question or main problem discussed in the study?
ReplyDeleteThe main problem discussed in this study is to determine whether the. modified Robinson-HO skin type color bar could provide assistance to healthcare providers in identifying early skin changes and injuries in patients with darker skin tones. This is an important topic to discuss as healthcare providers because the early signs of skin injuries (especially pressure injuries) can be difficult to be identified in darker skin tones. Typically, visual assessment is used to identify any signs of skin color changes or erythema. This problem is important in the healthcare system as it a lead to worsening tissue damage and cause an increase in patient complications.
2. Discuss the sample size used in the study
This study is limited in a sense that it only consisted of 42 adult participants with the average age of about 50 years old. Initially the goal of the sample size for this pilot research was 44 patients. In this study, 57% of the participants were identified as male. Additionally 76 % identified themselves as black and 67% identified as not of Spanish/Hispanic origin.

ReplyDeleteIn this article fecal incontinence is being defined as the involuntary loss of rectal flatus, feces, and mucus for a period of at least one month in a person that was previously continent. There are many causes of fecal incontinence from IBS, various drugs like antibiotics, and consumption of stomach irritants like caffeine and alcohol. The article’s goal was to investigate if nursing care can prevent fecal incontinence. Some of the methods to help with fecal incontinence are dietary supplements, bowel training, and proper hygiene and skin care. Dietary fiber like psyllium has been shown to improve patient’s stool consistency and reduce the incidence of fecal incontinence, although the article states there is little evidence of this, I have cared for many patients in the acute care setting that also use psyllium and report no episodes of incontinence and overall healthy bowel movement patterns. Nurses play a crucial role in providing care for patient with fecal incontinence, from cleaning to assisting with timed toileting.
How does this research article compare to our practice, policy and/or procedure?
In our ministry the recommendations/practices that this article is discussing are already in practice. Timed toileting time is a practice that I have seen implemented, especially in the rehabilitation unit, however the times that I have seen timed toileting being used, it has mostly been for urinary incontinence. The bedside nurse along with the help of the wound care team ensure proper skin care and hygiene practices are being followed, skin check procedure have been put in place to ensure that proper skin care is being followed when a patient is having incontinence episodes to prevent skin breakdown. The use of the “.skinassessment” phrase is used to assess a patient’s skin for pressure injuries, but within that checklist things like nutrition consult is included. When nutrition consults are done I have not seen psyllium fiber be recommended but other vitamins and supplements to support skin health are recommended.

Identification of Skin Injuries in Patients with Dark Skin Tones using a Modified Robinson-Ho Skin Type Color Bar: A Pilot Study
ReplyDelete1. Discuss the sample size used in the study.
The targeted goal for the sample size was originally supposed to be 44. Although the study team all agreed that a sample size of 42 was sufficient. This was due to the saturation of the targeted population had been achieved. The participants had to be at least 18 years of age, no current skin breakdown issues, and be of darker skin tone to be considered a part of the study.
2. Discuss the research question or main problem discussed in the study.
The study was conducted to determine whether a skin tone-based guide would be beneficial to detect dark skinned people with skin injury changes more easily. For example, purple, blue, and burgundy color skin discoloration changes can be harder to differentiate in darker skinned participants. The study team wanted to attempt to use Robinson-Ho Skin Type Color bar to assess dark skinned people and help identify skin risk injuries earlier and appropriately.
Discuss the limitations of the article: Limited sample size, design flaws, and or author bias
ReplyDeleteOne limitation of this study is the lack of data from a large sample group. The study itself only included data from 42 patients, in which the results from the data did not produce the changes in skin conditions they were hoping to evaluate. The study was also limited due to the fact that data collected was from only one surgical acute care unit, limiting how this study may affect different patient populations. The assessment tool for evaluating patients skin also had its limitations in regards to consistency when trying to determine a baseline for the patients skin conditions due to other factors such as lighting, positioning and vascular skin changes.
What are the advantages and disadvantages to the proposed recommendations in the article?
Although the data was limited, one big advantage of the proposed recommendations of this study include having another assessment tool to better understand, correctly evaluate and assess skin and the possibility of breakdown. The more tools we as nurses have available to us, help to improve our assessment skills and treatment plan. Although the study was aimed at creating better assessment tools for skin breakdown, a disadvantage to the study was that the results were inconclusive in regards to demonstrating skin changes they were hoping to evaluate.

The limitations of this study is the wide range of skin tones on the sacrococcygeal area and heels. The study also did account for the skin tone changes that occurred according to the acuity of the patient’s illness. Also during the study period, the SICU had less complicated patients than the normal so the study may not be reflective on the unit’s “normal” acuity. The study also did not have funding for translation services so they were not abla to include non English speaking patients.

1. Discuss the research questions or main problem discusses in the study.
This study highlights the challenges healthcare staff endure when assessing the beginnings of skin injuries in darker skin patients. Generally, skin assessments encompass visualizing characteristics of color changes in a progressing wound. On darker skin this would be a less obvious finding. The issue with this study was there were limited subjects to assess subtle skin changes as the subjects developed deep tissue injuries.
2. What are the advantages and disadvantages of implementing the article recommendations on your unit and/or hospital?
We as a hospital definitely need to be as vigilant as possible to the notion that anyone is susceptible to pressures injuries and compromised skin integrity. The advantage is to highlight awareness that relying on visualizing the skin is not necessarily the best way to assess skin integrity. We need to also palpate pressures areas and lightly wipe suspicious areas to check for the presence of drainage, blood, secretions, and etc. Being more hands on with assessments is a tool that will enable healthcare providers to better assess skin integrity.
1, How does this research article compare to our practice, policy and/or procedure?
ReplyDeleteThe study is different from our usual practice because we do not routinely use the modified Robinson-Ho Skin Type Color Bar. The study used this tool to compare the patient’s baseline skin tone with later skin changes. However, the study could not show that the color bar was effective for early detection because only two patients developed skin injuries, and their injuries appeared suddenly without subtle skin color changes.
However, this study shows that skin assessment can be more difficult in patients with dark skin tones. Redness or purple/maroon discoloration may not be easy to see. Therefore, nurses should not only look for redness but also assess changes in skin temperature, texture, firmness or softness, pain, and changes from the patient’s normal baseline skin tone. This is important because early signs of a pressure injury may be missed in patients with dark skin tones.
2, What are the advantages and disadvantages to the proposed recommendations in the article?
There are several benefits of using the recommendations from this study in our unit. We have many patients who are at high risk for pressure injuries, and we perform skin assessments regularly. This study reminds us that redness may be difficult to see in patients with dark skin tones. Nurses should not only look at skin color but also assess skin temperature, texture, pain, and other changes from the patient’s baseline skin condition. This may help us identify skin injuries earlier and prevent them from getting worse. Another benefit is using a skin tone guide to identify and document the patient’s baseline skin tone. This can help nurses compare skin changes during the hospital stay.
Also, the study did not prove that the modified Robinson-Ho Skin Type Color Bar can detect all pressure injuries early. Only two patients developed skin injuries during the study, and both injuries appeared suddenly without subtle skin color changes. Therefore, I think the tool may be helpful for identifying baseline skin tone, but it should be used together with our regular visual and tactile skin assessment, not by itself.
1, How does this research article compare to our practice, policy and/or procedure?
ReplyDeleteThis study is a bit different from how we usually do things because we don't normally use that special Robinson-Ho skin color bar to track changes from a patient's baseline. In the end, the study couldn't really prove if the color bar helps catch injuries early, mostly because only two patients actually got hurt, and their injuries just popped up out of nowhere without any gradual color shifts.
The real eye-opener here is just how hard it is to spot skin damage on patients with darker skin tones, since typical redness or purple and maroon bruising doesn't show up easily. Because of that, nurses can't just rely on a quick visual check for redness. We have to look at the whole picture by feeling for changes in temperature and texture, checking if the skin feels unusually firm or soft, asking about pain, and noting any deviations from the patient's normal skin tone so we don't miss those critical early warning signs of a pressure injury.
2 Discuss the research questions or main problem discusses in the study.
This study underscores the distinct clinical challenges healthcare providers face when evaluating the initial stages of pressure injuries in patients with darker skin tones. Conventional dermatological assessments heavily rely on the visual inspection of erythema and localized color shifts to track wound progression. However, in patients with high melanin levels, these visual indicators are significantly less pronounced and frequently obscured. A notable limitation of this research was its insufficient sample size, which precluded the evaluation of subtle, gradual epidermal color changes, as the few participating subjects rapidly developed acute deep tissue injuries.
Discuss the research question or main problem discussed in the study.
ReplyDeleteThe study examines whether a modified Robinson-Ho Skin Type Color Bar can help nurses identify subtle skin changes and injuries in patients with dark skin tones. Early skin injuries may be difficult to recognize because redness or discoloration may not be easily visible. The study evaluates whether this tool can improve skin assessment and early detection of injury.
Discuss the limitations of the article.
A major limitation is the small sample size and the limited number of skin injuries that occurred during the study. The tool was unable to detect the subtle changes in the two patients who developed deep tissue pressure injuries. Larger studies with more diverse patients and different types of skin injuries are needed to determine the tool’s effectiveness.
Discuss the research question or main problem discussed in the study:
ReplyDeleteThe study focuses on the challenges and difficulty of detecting early skin injuries in patients with dark skin tones. The study addresses that the subtle change in color may be difficult in recognizing appropriate skin assessment which can then lead to worsening pressure injuries. The study evaluated whether the modified Robinson-Ho skin type color bar help nurses to use as a tool to identify skin early changes
as a method of skin assessment.
Discuss the method used by the author in the study:
A pilot study was performed in a surgical intensive care unit (SICU). Adult patients' who did not have existing skin pressure injuries with dark skin tones were included. The modified Robinson-Ho Skin type color bar was also used to establish the patients' baseline skin tone and then observed for skin injury development. The study was conducted in about two months.

ReplyDeleteWhat are the advantages and disadvantage of implementing the article recommendations on your unit and/or hospital?
ReplyDeleteThe advantages are that there are the useful clinical pearls in this article, which we would adopt to our skin protocol if we will develop the bundle to improve on dark skin toned patients. For example, our standard skin assessment should be pared with tactile one, such as texture, temperature and sensation. That way, we can detect 'boggy feeling to touch, and pain resulting in identifying the skin injuries even without skin break down. In order to notice skin injury among the mixed-race patients, we should rely on visual inspection, instead of race/ethnicity. The article also highlights importance of standardization of daily assessments for consistent skin assessment, such as the source of light or skin prep. Our skin prep is consistent using specific products, which are determined by our WOCN thankfully, but our source of light is often not available due to poor maintenance.
The biggest disadvantage is that their modified Robinson-Ho Skin Type Color Bar was not useful to detect subtle changes of skin injury. Without a skin tone-based tool, our skin assessment would be very difficult and confusing, which reduces consistency of assessment and rises skin injury. We need not only a good amount of training, but also annual follow-up education to achieve and keep the good assessment skills, which would be time-consuming requiring patience and can be costly. As for the standardization for daily assessment, buying and maintaining the source of light efficient can be problem together with its cost since a flashlight, our source of light is supposed to be available in each room of ICU, but it's not always useful because we find the battery often gets low or dead because everyone is responsible, which is ended no one to maintain it.
Discuss the research question or main problem discussed in the study?
I believe the main problem in this article is that their modified Robinson-Ho Skin Type Color Bar did not empower the routine visual/tactile skin assessment to detect early signs of skin injury in patient with dark skin tones even though they proved that this objective tool was reliable to use producing the same result among the clinicians. They concluded this skin tone-based guide was useless since the 2 wounds were developed without the first subtle sign. The researcher points out the guide cannot work to catch the first sign due to the wide variations of skin tone in their heels and in their baseline skin tone in the sacrococcygeal region. In addition to these problems, the pigmentation can be different due to leg position or clinical condition, such as hypo-perfusion or edema. In our ICU, our critical patients often show skin mottling due to hypo-perfusion, edema due to circulatory problem and ecchymosis due to coagulopathy, our assessment of the skin pigmentation in dark skin patients is complicated and very difficult to catch the early sign of skin injury. As the article mentions, I hope we would adopt the devices that able to spot the early change of skin tone near future even though there might be a budget problem. In order to reduce the incidents and deterioration of skin injury among the dark skin population, visual/tactile assessment alone can be labored and time-consuming resulting increased risk of lack of consistency in assessment among the clinicians. In Skin Symposium, somebody mentioned about herald AI assisted devises for skin assessment in Keck. Personally I am very curious how those devices identify the first signs of skin injury since the article says these kind of devices are not influenced by pigmentation. I do agree that our assessment should not been taken over by the devices including AI, but their objective eye can be very helpful for our clinical decisions.
Discuss the sample size used in the study.
ReplyDeleteThe researchers planned to include 44 patients, but the final study included 42 patients. Most of the participants were Black, and everyone included had a darker skin tone based on the tool being studied. Since this was a pilot study, the smaller sample helped the researchers test whether the skin tone tool could work before doing a larger study. However, using only 42 patients makes it harder to know if the same results would be seen in a larger group of patients.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
One limitation was the small sample size of only 42 patients from one hospital unit. The patients during the study were also less critically ill than the patients normally treated on that unit, so the results may not fully represent the usual patient population. Another limitation was that the skin tone tool could not always account for differences in skin color around areas such as the heels and sacrum. The study also did not include patients who did not speak English because translation services were not funded, which limited the types of patients who could participate.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias
ReplyDeleteThere were several limitations in this pilot study related to the overall sample size and design. The pilot study used a modified Robinson-Ho skin type color bar; however, they did not realize that the tool would not be able to determine the skin tone changes in the areas on or by the sacral coccyx and the heels. The research team realized during the study that there was a wide range of skin tone variation in those areas that the skin color bar could not determine whether a pressure injury was forming. The sample population was 42 participants, but among the participants on the unit, many were less critically ill than what is considered normal for the acute and critical care unit during the study period. Due to this finding, the findings may not have correctly portrayed what is typical for this unit. The research team also mentioned that they did not budget for interpretation services, so non-English speaking patients were excluded.
Discuss the sample size used in the study.
In this pilot study to identify pressure injuries utilizing a modified Robinson-Ho skin type color bar, the ideal goal sample size was 44 participants at large urban medical center in an acute and critical care unit. The number was determined on the research team's previous past experience with the patient population and there was already feasibility established. While the study was being conducted, there was an updated total sample size of 42 due to sample saturation. The research team discussed and agreed that the sample saturation had been reached so no further recruitment was needed.
1) Discuss the research question or main problem discussed in the study?
ReplyDeleteThe study examines how fat-tissue thickness affects muscle stress and strain in people with transfemoral amputations and their risk of deep tissue injury (DTI) under the prosthetic socket. Researchers used 3-D models with different fat-layer thicknesses and simulated socket use and standing. They compared muscle compression and strain with known cell-death thresholds to identify which fat levels may increase the risk of hidden, deep pressure injuries.
2) what are the advantages and disadvantages of implementing the article recommendations on your unit and/or hospital?
On a rehab unit this would give you a quick flag for very lean residual limbs—fat under about 6 mm or body-fat under 10%—so you could watch donning more closely and follow those patients tighter. The problem is it comes from one computer model of one stump, and whole-body BMI still doesn’t tell you what’s actually sitting over the cut femur. You also can’t just add fat on command, measuring thickness properly takes ultrasound and time, and it’s easy to chase the number while missing a poorly fitting socket.
ReplyDelete1) What are the advantages and disadvantages to the proposed recommendations in the article?
The paper basically says hospitals should stop using race as a stand-in for skin tone, instead use a simple color-bar tool to record a patient’s baseline, build that into the charting system nurses already use, and look at gadgets that can pick up early tissue damage even when pigment hides it. That’s useful because it gives a more objective starting point, nurses could apply the bar without extra training and still mostly agreed with each other, and it might help catch problems before they become full-thickness wounds. The catch is that the color bar didn’t actually help with the two injuries that showed up in the study—they appeared suddenly instead of as faint color shifts—and it struggles with the natural patchiness on heels and the sacrum, changing light, and how sick patients’ skin can look from poor perfusion. The tech ideas also cost money and haven’t been proven at scale yet, especially in a small pilot where almost no early injuries even occurred.
2). Discuss the sample size used in the study.
They set out to enroll 44 patients because that felt doable from their earlier quality-improvement work on the same unit, and they ended up with 42 after a full year when they decided they’d hit saturation. That’s a typical pilot-study size, but it’s still small—and the real problem is that only two people actually developed a wound, neither of which showed the subtle color shift the tool was supposed to catch. So they never really got to test the main question, and the sample also happened to be less critically ill than the unit usually sees, which may have kept injury rates even lower.
Discuss the research question or main problem discussed in the study.
ReplyDeleteThe main problem is that beginning skin injuries like stage 1 can be missed in patients with darker skin because redness and discoloration don't present in the same way. When pressure injuries are not caught early, they will continue breaking down until obvious breakdown occurs. The researchers wanted to see if a modified Robinson-Ho skin type color bar used during skin assessment would help nurses notice early changes. The second goal was to find out if two nurses using the tool would pick the same skin tone for the same patient.
Discuss the sample size used in the study.
The researchers used 42 patients for a year to collect data. All of the patients were adults with darker skin tones and no noted skin injuries at the beginning of the study. This study took place in one surgical ICU unit. The group was small and only two patients ended up developing skin injuries, therefore the researchers could not determine if the tool helped catch injuries early.
Describe the method used by the author of the study.
ReplyDeleteThe authors used a prospective observational pilot study involving 42 adult patients with dark skin tones. Researchers used a modified Robinson-Ho Skin Type Color Bar to assess and document the patients’ baseline skin color, and monitored them for changes that could indicate skin injury. Multiple clinicians performed assessments to determine how consistently the tool could be used.
Discuss the sample size used in the study.
ReplyDeleteThe study had a final sample size of 42 adult patients with dark skin tones. The researchers originally planned for 44 participants but stopped at 42 after reaching sample saturation. Because it was a small pilot study and only two participants developed skin injuries, the findings were limited in determining how effective the color bar was at detecting early skin changes.
1) Discuss the sample size used in the study:
ReplyDelete- The study enrolled 42 adults, just short of a goal of 44 that the authors set based on "prior experience and feasibility" rather than a power calculation or any estimate of how many injuries to expect. For a pilot study, a small sample is acceptable, since the goal is to test feasibility and refine methods, but the size matters differently for each aim. For the primary aim, detecting early skin tone change from injury, what counts is the number of injury events, not the number of patients, and only two of the 42 participants developed a wound. Both were sudden and obvious, so the aim could not be evaluated at all, and the authors admit the low sample size prevented them from learning whether the tool would detect subtle changes in other wound types.
2) Discuss the research question or main problem discussed in the study:
- The study addresses a specific equity problem in pressure injury care: early skin injuries are harder to detect in patients with dark skin tones, and missed early detection lets wounds progress to more severe, costly, and deadly stages. In lighter skin, the first warning sign is usually redness that may or may not blanch under pressure. In darker skin, eumelanin can mask that redness and the purple or maroon discoloration that typically follows, so an injury may show up instead as a subtle hyperpigmented or hypopigmented patch, a boggy or firm feel, temperature change, or pain. The authors point to disparities in the literature, including higher incidence, severity, and mortality from pressure injuries in Black patients, and to two clusters of preventable full-thickness wounds on their own unit in patients with dark skin, as evidence that current visual and tactile assessment is missing these early changes. Existing tools are also imperfect: the Fitzpatrick scale was built around sun reactivity in lighter-skinned people, the Munsell chart includes many colors that don't resemble human skin, and race or ethnicity, which is often used as a stand-in, is self-reported and does not reliably reflect actual skin tone. From this, the study poses two questions. The first, which is the primary one, is whether adding a modified version of the Robinson-Ho Skin Type Color Bar (limited to its darker rows and used alongside the usual visual and tactile exam) can detect subtle changes in skin tone at the sacrum and heels that signal early injury in patients with dark skin. The second is whether the tool is reliable between raters, meaning that two nurses independently assessing the same patient would choose the same swatch. The authors also carry a related hypothesis that an objective, tone-based scale would categorize patients' risk better than race or ethnicity does. The underlying goal, framed through Levine's Principle of Conservation of Structural Integrity, is to preserve skin integrity by catching damage early enough to intervene. It is worth noting that the paper answers the second question far better than the first: the primary question could not be evaluated because no one developed a subtle change, so the study ends up speaking mainly to reliability and to the weakness of race and ethnicity as proxies for skin tone.
1. Discuss the research question or main problem discussed in the study.
ReplyDeleteThe main problem discussed in this study was the difficulty of identifying early skin injuries in patients with dark skin tones. Early signs of pressure injuries, such as redness or changes in skin color, can be harder to see on darker skin. If these changes are missed, the injury may become worse before it is recognized and treated.
The researchers wanted to determine whether the modified Robinson-Ho Skin Type Color Bar, when used along with the usual visual and tactile skin assessment, could help nurses recognize subtle skin tone changes that may indicate an early skin injury. They also wanted to determine whether different nurses could use the tool and obtain similar results. Although the study did not show that the tool was effective at detecting early skin injuries, it did show moderate reliability between nurses when identifying a patient's baseline skin tone.
2. Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
One limitation of this study was the small sample size. The researchers planned to include 44 patients but ended with only 42 participants. Two patients developed a skin injury, and neither injury showed the subtle skin color changes the researchers were hoping to study. As a result, the researchers could not determine whether the modified Robinson-Ho Skin Type Color Bar could identify early skin injuries in patients with dark skin tones.
The design limitation included only one acute and critical care unit, and patients during the study period were less critically ill than those normally treated on that unit. The researchers also found that skin tone naturally varied in areas such as the heels and sacrococcygeal area, making the color tool more difficult to use. In addition, the authors excluded non-English-speaking patients because translation and interpretation services were not available. These limitations make it harder to apply the results to a larger and more diverse patient population. The article provides clear evidence of significant author bias because the researchers openly discussed the study's weaknesses and limitations.
Describe the method used by the author of the study.
ReplyDelete• Design: Prospective, observational cohort study.
• Setting: A surgical intensive care / acute care unit within an urban, academic hospital.
• Participants: Hospitalized adults (≥ 18 years old) who entered the unit with no pre-existing skin injuries but possessed a confirmed dark skin tone baseline.
Discuss the limitations of the article: limited sample size, design flaws, and/or author bias.
The most significant limitation of the study is the extreme shortage of clinical events (wounds) to evaluate.
Statistical Power: Because only two injuries occurred, the authors lacked the sample breadth required to definitively test if the tool could identify slow-evolving, subtle skin changes. Two data points are insufficient to claim a tool is globally "ineffective" for all early-stage injuries rather than just the specific acute presentations witnessed.
Potential Author and Literature Bias:
• Confirmation Trap Regarding Race Data: The authors explicitly highlight that self-reported race or ethnicity is not a reliable proxy for skin tone. However, in structuring a tool designed specifically around visual charts, the research remains tethered to a paradigm that tries to fix visual evaluation rather than pivoting toward objective, non-visual technological assessments (like sub-epidermal moisture scanners).
• The "Pilot Study" Mandate: As a pilot study, it is intentionally designed to explore feasibility rather than establish definitive clinical protocol. A structural bias exists toward finding any baseline utility—which explains why, despite failing its primary aim (detecting injury), the study frames the moderate inter-rater reliability as a major victory for baseline skin tone tracking
