Influence of Hospital Volume on Mortality and Short-term Postoperative Outcomes in Uncomplex General Surgery in Switzerland

The effect of centralisation measures on the operative outcomes after any type of surgery in Switzerland has not been highlighted yet. This study aims to investigate the influence of the annual case-specific hospital volume on uncomplex general surgery. The four operations investigated are appendectomy, cholecystectomy, umbilical hernia repair, and inguinal/femoral hernia repair.
