    [Does hospital volume correlate with surgical process time? : Retrospective analysis of the five most common procedures for visceral surgery, trauma and orthopedic surgery and gynecology/obstetrics from the benchmarking program of the Berufsverband Deutscher Anästhesisten (BDA), Berufsverband Deutscher Chirurgen (BDC) and Verband für OP-Management (VOPM)].

    BackgroundMinimum volume thresholds for specific surgical procedures in German hospitals were established in 2004 but remain controversial. For the first time, this study investigated the relationship between hospital performance volume and surgical procedure duration in a multicenter approach. The question here was whether a concentration on frequently performed procedures leads to a reduction in surgical process times.MethodsIn a retrospective analysis, the 5 most common procedures from visceral, trauma/orthopedic and gynecological/obstetrics surgery were examined in hospitals participating in a benchmarking program. For each procedure performed between 2013 and 2015, hospitals were divided into 4 groups depending on the hospital volume provided. The average surgical duration of incision to suture time was calculated between the group with "very low" hospital volume and the other three groups ("low", "high" and "very high").ResultsOR cases from 75 hospitals were analyzed. The number of included cases per procedure ranged from 31,940 to 2705. The average number of operations performed in a specific procedure was 3-4 times higher in high-volume hospitals compared to very low-volume hospitals. A linear relationship between hospital volume and surgical process time only appeared to be clearly seen in laparoscopic cholecystectomy, appendectomy and arthroscopic meniscus surgery: a higher case load led to a reduction in incision to suture time. For the other procedures, the surgical process times were inconsistent between the hospital groups.ConclusionThe case volume only appeared to have a direct but limited influence on incision to suture times in laparoscopic and arthroscopic procedures. Overall, the hospital performance volume appeared to be of subordinate importance in terms of OR-economics.
