Abstract

Background: Obese patients may have unique surgical needs. The goal of this study is to determine if there is an association between obesity and transfer in patients undergoing EGS.

Methods: EGS patients were identified in the NSQIP 2011-2016 database. Outcome variables included interhospital transfer, days to surgery, SSI, postoperative LOS, discharge destination, and 30-day readmission. Descriptive statistics and multivariable regression were utilized.

Results: 419,373 EGS patients were identified, and transfer status varied by obesity class. After controlling for other factors, obese patients had increased odds of interhospital transfer (OR = 1.07-1.53), SSI (OR = 1.22-1.69), and decreased odds of discharge to home (OR = 0.42-0.71, all p < 0.01) but not of 30-day readmission or delay from admission to surgical intervention.

Conclusions: Obese patients undergoing EGS procedures have an increased likelihood of transfer from an acute care hospital. As obese EGS patients are increasingly prevalent, determining best triage practices for this unique patient population warrants additional investigation.
