Describe the method used by the author of the study.
ReplyDeleteThe method used in this study was a multi-institutional cohort study that had undergone colorectal resection between the years of 2003-2014. Patients were selected based on the interpretation of a Healthcare inpatient administrative database, representing a 20% sample size of all US based hospitals. The method compared research across the database to make selection of the sample size for comparable data. There were specific patients excluded including those under the age of 18 and patients who underwent both a procedure of colostomy and ileostomy formation.
Discuss the research question or main problem discussed in the study?
This study focuses on two different problems related to fecal ostomy surgery, the development of a potential permanent ostomy and patient outcomes. The first problem of focus in the study is the rate of which fecal ostomy operations are performed for patients who undergo colorectal resection due to severe bowel symptoms, intestinal obstruction, avoidance of pelvic infections or reducing symptoms of incontinence. The second problem of focus is to compare the rates of colostomy formation between groups of patients younger and older than age 65; to see the overall impact of quality of life after colostomy formation.
1. Discuss the limitations of the article: limited sample size, design flaws and/or author bias?
ReplyDeleteOne limitation of the article is that the database they used does not include the clinical decision making that led to ostomy formation, such as presence of tissue or tension when attempting to create the anastomosis which can obscure the clinical context and rationale behind the procedure.
The authors also did not include the operations with ostomy formation without a colorectal resection which underestimate the overall number of patients living with ostomy.
Finally, the database used by the authors did not provide longitudinal data and the authors were unable to evaluate hospital readmissions or rates of ostomy reversals.
2. Discuss the method used by the author of the study?
The method used by the author is a multi-institutional cohort study of patients undergoing colo-rectal resection from 2003 to 2014. Identified data were obtained from the Nationwide Inpatient
Sample Database.
The data set contains hospital and patient specific information in a representative sample. Hospital records from approximately 1000 hospitals across the U.S. which represents the 20% sample of
the hospital until 2012 was used.
Patients included in this study had a hospital admission during which a colo-rectal resection with or without was performed. Patients younger than 18 years old were excluded.
