The impact of COVID-19 pandemic on patient selection and access to care, approach type, and postoperative outcomes in bariatric surgery

Abstract

BackgroundThe COVID-19 pandemic had affected the health systems across the world since early 2020 with a concern about access to medical care during the first wave of COVID-19 pandemic. ObjectivesThe objective of this study was to examine how the COVID-19 pandemic influenced patient selection, approach type, and postoperative outcomes in elective bariatric surgery. SettingUnited States. MethodsData from the MBSAQIP database for the years 2016–2020 were queried. Wilcoxon rank-sum test and Fisher's exact test were employed for continuous and categorical variables, respectively. Postoperative outcomes within 30 days were assessed separately and based on the Clavien-Dindo (CD) classification of III-V. χ2 test and logistic regression were used to compare outcomes between procedure and approach types, as well as surgical operation periods. ResultsA total of 741,620 patients underwent robotic and laparoscopic sleeve gastrectomy and Roux-en-Y gastric-bypass. The cases performed in 2020 exhibited lower comorbidities and postoperative complications compared to prepandemic years, regardless of the approach type. Notably, the proportion of White patients decreased during the pandemic, while there was an increase in the number of African American and Hispanic patients who had bariatric surgery. ConclusionsPatients who underwent bariatric surgery during the COVID-19 pandemic appeared to be healthier with fewer comorbidities and experienced fewer adverse postoperative outcomes compared to those who had surgery prior to the pandemic. This study highlights the limited access to bariatric surgery for high-risk patients during the pandemic.
