Background: The aim of the study was to characterize the prevalence of obstructive sleep apnea (OSA) in elective bariatric surgery patients and to determine if OSA is an independent predictor of 30-day serious complications and 30-day mortality among bariatric surgery patients.
Methods: An analysis of the MBSAQIP database from 2015 to 2019 was conducted, and patients were stratified by OSA diagnosis. Data was extracted on patient age, sex, race, and comorbidities. A multivariate logistic regression model was created to evaluate the impact of OSA on 30-day serious complications and 30-day mortality.
Results: Of 751,952 patients, 287,180 (38.2%) were identified as having OSA. OSA patients were older (48.0 ± 11.4 vs. 42.2 ± 11.9 years; p < 0.0001) and were of increased BMI (46.5 ± 8.5 kg/m vs. 44.6 ± 7.3 kg/m; p < 0.0001). OSA was not associated with 30-day mortality in the multivariable logistic regression model (OR 0.98, 95% CI 0.83-1.16; p = 0.829). OSA was associated with increased odds of 30-day serious complications (OR 1.33, 95% CI 1.30-1.36; p < 0.0001). In addition, dialysis (OR 3.07, 95% CI 2.68-3.52; p < 0.0001), positive venous thromboembolism history (OR 2.46, 95% CI 2.32-2.60; p < 0.0001), and oxygen dependence (OR 2.42, 95% CI 2.18-2.68; p < 0.0001) were all identified as major predictors of serious complications.
Conclusion: We identified OSA as a modifiable factor predictive of serious complications following elective bariatric surgery. OSA is highly prevalent in this patient population, and it appears to be an important risk factor that deserves further attention in terms of peri-operative optimization strategies.
