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.

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.
