Does accreditation matter? An analysis of complications of bariatric cases using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program and National Quality Improvement Program databases.

Abstract

Two large nationwide databases collect data on common operations in the United States. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) collects bariatric data, whereas the National Quality Improvement Program (NSQIP) gathers details on a broader range of general surgical cases. Evaluate the differences in rates of complications between both databases regarding Roux-en-Y gastric bypass and sleeve gastrectomy. National databases, United States. We evaluated the MBSAQIP and NSQIP from 2017 to 2019 using the procedure codes 43644 and 43775. Fifteen common complications were evaluated. Propensity-matched analyses (PMAs) were done to control for differences across databases. Significantly different variables after a PMA were included in multivariable models. The data were examined for differences between the 2 databases before and after the PMA, with and without adjustment for operation type. There were 483,361 cases reported in the MBSAQIP and 57,598 in the NSQIP. PMA matched 57,479 cases for each database. Seven complications were different, with higher rates reported in the NSQIP than in the MBSAQIP: myocardial infarction, sepsis, organ/space surgical site infections, deep vein thrombosis, urinary tract infections, pulmonary embolism, ventilator dependence >48 hours, and pneumonia. When adjusting for the procedure performed, sleeve gastrectomy in the NSQIP had higher rates of organ/space surgical site infections, deep vein thrombosis, sepsis, and death. Roux-en-Y gastric bypass in the NSQIP had higher rates of organ/space surgical site infections, ventilator dependence >48 hours, urinary tract infections, myocardial infarction, deep vein thrombosis, and sepsis. When compared with the MBSAQIP, the NSQIP reports higher rates of bariatric complications. Further studies are needed to confirm the reasons behind this.
