Abstract
Bariatric surgery outcomes in elderly patients have been shown to be safe, but with a higher rate of adverse outcomes compared with nonelderly patients. The impact of race on bariatric surgery outcomes continues to be explored, with recent studies showing higher rates of adverse outcomes in black patients. Perioperative outcomes in racial cohorts of elderly bariatric patients are largely unexplored.The goal of this study was to compare outcomes between elderly non-Hispanic black (NHB) and non-Hispanic white (NHW) bariatric surgery patients to determine whether outcomes are mediated by race.Academic hospital.Patients who had a primary Roux-en-Y (RYGB) and sleeve gastrectomy (SG) in the period 2015-2018 and were at least 65 years of age were identified from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Participant Use Data File (MBSAQIP PUF). Selected cases were stratified by race. Outcomes were compared between matched racial cohorts. Multivariate regression analyses were performed to determine whether race independently predicted morbidity.From 2015 to 2018, 29,394 elderly NHW (90.8%) and NHB (9.2%) patients underwent an RYGB or SG. At baseline, NHB elderly patients had a higher burden of co-morbid conditions, resulting in higher rates of overall (7.7% versus 6.4%, P = .009) and bariatric-related (5.4% versus 4.1%, P = .001) morbidity. All outcome measures were similar between propensity-score-matched racial elderly bariatric patient cohorts. On regression analysis, NHB race remained independently correlated with morbidity (odds ratio [OR] 1.3, 95% CI 1.08-1.47, P = .003).RYGB and SG are safe in elderly patient cohorts, with no differences in adverse outcomes between NHB and NHW patients, accounting for confounding factors. While race does not appear to impact outcomes in the elderly cohorts, NHB race may play a role in access.
