Preoperative and Postoperative Factors Associated with 30-Day Postoperative Emergency Room Visit for Bariatric Patients in the United States: A Systematic Review of the Literature

This literature review explores 30-day emergency room (ER) visits for patients who go through bariatric surgery, an elective surgical procedure. The study delves into obesity and bariatric surgery trends and factors in 30-day postoperative ER visits for bariatric patients, utilizing PubMed and SCOPUS databases. While most published peer-reviewed articles cover a mix of preoperative, intraoperative, and postoperative factors, almost no articles focus solely on preoperative factors impacting 30-day postop ER visits. This study contributes to the field in the way that it synthesizes and narrows down preoperative factors in one place and provides recommendations emphasizing these preemptive measures to optimize the healthcare system in the US for the patient population undergoing bariatric procedures. In the future, a model can be developed solely considering the preoperative factors to predict and minimize the possibility of 30-day postop ER visits, which can help reduce cost.
