Assessing the relative influence of hospital and surgeon volume on short-term mortality after radical cystectomy.

ABSTRACT:

Objectives

To assess the relationship between surgeon (SV) and hospital volume (HV) on mortality after radical cystectomy (RC).

Patients and methods

We queried the National Cancer Database (NCDB) for adult patients undergoing RC between 2010 and 2013. We calculated average volume for each surgeon and hospital. Using propensity-scored weights for combined volume groups with a proportional hazards regression model, we compared the associations between HV and SV with 90-day survival after RC.

Results

A total of 19 346 RCs were performed at 927 hospitals by 2 927 surgeons in the period 2010-2013. The median (interquartile range) HV and SV were 12.3 (5.0-35.5) and 4.3 (1.3-12.3) cases, respectively. For HV, 90-day unadjusted mortality was 8.5% in centres with <5 cases/year
