Background:
Robotic surgery utilization has been increasing across surgical specialties; however, racial disparities in patient access to care and outcomes have been reported.
Objectives:
In this study, we examined racial disparities in the utilization and outcomes of robotic bariatric surgery over an 8-year period.
Setting:
Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP) centers of excellence across the United States.
Methods:
The MBSAQIP database was used to identify adult patients who underwent robotic bariatric surgery between 2015 and 2022. Patients were stratified according to race and ethnicity into non-Hispanic White, non-Hispanic Black or African American (AA), Indigenous, Asian, and Hispanic patients. Multivariable analyses were used to assess predictors of robotic surgery use, odds of minor and major complications, prolonged length of stay (prolonged length of stay (pLOS): ≥3 days), readmissions, reoperations, and mortality within 30 days.
Results:
Out of 1,288,359 patients included, robotic surgery was utilized in 196,314 patients (15.2%), with a mean age of 44 ± 12 years and 80.6% females. Rates of robotic surgery increased to 30% by 2022. Compared to White patients, Black/AA patients were more likely to undergo robotic surgery (adjusted odds ratio (aOR) = 1.22, 95% confidence interval (CI) = 1.21-1.24, P < .001). The safety of robotic bariatric surgery improved for both White and Black patients with decreased odds of major complications, readmissions, reoperations, and pLOS over the study period. However, Black/AA patients were more likely to experience minor and major complications, readmissions and have pLOS compared with White patients in 2022 (aOR:1.26, 95% CI:1.19-1.34, P < .001; aOR:1.22, 95% CI:1.06-1.41, P = .006; aOR:1.44, 95% CI:1.28-1.62, P < .001; aOR:2.26, 95% CI:2.06-2.47, P < .001, respectively).
Conclusion:
The utilization of robotic bariatric surgery has increased significantly over the past 8 years with continued improvements in its safety profile. While Black/AA patients have improved access to robotic surgery, their clinical outcomes continue to be worse than those of White patients. Efforts to address racial disparities in bariatric surgery outcomes must remain a priority to achieve health equity.
