Impact of the COVID-19 Pandemic on Metabolic and Bariatric Surgery Utilization and Safety in the United States

Background: Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for severe obesity. The utilization and health and safety outcomes of MBS in the United States (US) during the COVID-19 pandemic versus 2015–2019 among adolescent and adult populations and by ethnic group is largely unknown. Methods: The 2015–2020 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) longitudinal (30-day) cohort data was used to compare adolescent and adult (N = 1,134,522) post-operative outcomes and to calculate MBS utilization pre-pandemic (2015–2019) versus pandemic (2020). Cochran-Armitage trend tests compared MBS utilization and safety outcomes over time from 2015 to 2020. Logistic regression analysis compared the odds of hospital readmission and MBS completion pre-pandemic versus pandemic by key characteristics. Results: MBS utilization increased by 8.1% among youth (from 970 to 1140 procedures) and decreased by 10.2% among adults (from 205,232 to 167,384) from 2019 to 2020, respectively. MBS increased by 18.5% during the pandemic for youth who identified as other/multiracial (P trend < 0.001). Among US youth, the number of reoperations and reinterventions significantly decreased over the 6-year time frame (P trend <.001). Among US adults, 30-day post MBS mortality, reoperations, readmissions, and reinterventions all showed a significant decrease over time (P trend <.001) while septic shock and sepsis increased from pre-pandemic to the first year of the pandemic (P trend < 0.001). Conclusion: In comparison to 2019 (or to previous years), US MBS utilization increased for youth but decreased for adults during the first year of the COVID-19 pandemic. Safety outcomes were comparable to those of the pre-pandemic years. Graphical abstract: [Figure not available: see fulltext.].
