Impact of Hospital volume on postoperative outcomes after radical prostatectomy: A 5-Year nationwide database analysis.

Abstract Background Hospital volume is considered to be a quality measure for outcomes after major oncological surgery. However, countrywide data are lacking for radical prostatectomy (RP). Objective To assess the impact of hospital volume on postoperative outcomes after RP performed using an open (ORP) versus a minimally invasive surgery (MIS, including pure and robot-assisted RP) approach. Design, setting, and participants Data for patients undergoing RP in France from 2014 to 2019 were extracted from the central database of the national health care system. Outcome measurements and statistical analysis Primary endpoints were length of hospital stay (LOS), complications (measured as severity index [SI] scores), and hospital readmission rates at 30 and 90 d. Results and limitations The median annual hospital volume was 19 RPs (interquartile range 1–40) in the overall cohort. MIS was associated with better outcomes than ORP. Greater hospital volume was correlated with shorter LOS (p Conclusions This nationwide analysis of RP procedures shows a significant correlation between hospital volume and postoperative outcomes irrespective of the surgical approach. Very low case volume ( Patient summary In this study we analysed the French nationwide database for removal of the prostate for prostate cancer. We found that the number of these cases that a hospital carries out per year was associated with outcomes after surgery, with better outcomes for higher annual case numbers.
