Benchmarking outcomes in laparoscopic bariatric surgery
The purpose of this study is to identify the best possible outcome (i.e. benchmarking) using data from high-volume centers that may serve as “negative controls” for comparison with single center outcomes, high-risk patients, and future developments.
Data collection and study design are based on to the newly defined standardized reporting for benchmarking, as published in Annals of Surgery in 2016. This multicenter cohort study will include several high volume centers from around the globe performing over 200 bariatric procedures per year, with 90-day follow-up data from a 5 year period (i.e. 01.06.2012 to 31.05.2017).
Every center included in the study must have a prospective database from which data can be collected as well as previous publications critically reporting on their outcome.
The study has been approved by the Cantonal Ethics Committee of Zurich, Switzerland: BASEC-nr 2017-01652, 17th October 2017.
