Background:
Readmission after bariatric surgery is not cost-effective and is a preventable quality metric within standardized practices. However, reasons for readmission among racial/ethnic bariatric cohorts are less explored and understood.
Objective:
Our study objective was designed to compare reasons for readmission among racial/ethnic cohorts of bariatric patients.
Setting:
Academic hospital.
Methods:
We performed a retrospective analysis of the 2015-2018 MBSAQIP databases to identify Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) cases. Regression analyses determined predictors of all-cause and bariatric-related readmissions. Reasons for readmission were compared between racial/ethnic cohorts using propensity score matching.
Results:
More than 550 000 RYGB and SG cases were analyzed. The readmission rate was 3%-4%. Black race, RYGB, robot-assisted approach, and numerous co-morbidities were independently associated with readmission (P <.05). In RYGB cases, black (versus white) patients were at decreased odds of leak-related (P < .001) and cardiovascular-related (P < .001) readmissions but at increased odds of readmissions related to renal complications (P < .001). Hispanic (versus white) patients had a higher likelihood of venous thromboembolism-related readmissions (P < .001). In SG cases, black (versus white) patients had a similar lower likelihood of readmission related to leaks or cardiovascular complications but higher odds of readmission related to renal complications (P < .001). Hispanic (versus black) patients had a higher likelihood of leak-related readmissions (P < .001).
Conclusion:
Readmission reasons after bariatric surgery vary by race/ethnicity. Perioperative pathways to mitigate complications, including readmissions, should consider these disparate findings.
