The Association of Trainee Involvement in Radical Cystectomy With Perioperative and Oncologic Outcomes.

ABSTRACT

OBJECTIVE: To assess the impact of trainee involvement in surgery on perioperative and oncological outcomes of patients undergoing radical cystectomy (RC). MATERIALS AND METHODS: We reviewed the records of patients undergoing RC for urothelial carcinoma between 2000 and 2015 at our institution. Trainee level was categorized as fellow, chief, senior and junior residents. Demographic, perioperative and oncological outcomes were recorded and compared between the groups. Specifically, operative time, 30-day complications, severe complications (Clavien III-V) and oncological outcomes (overall, cancer-specific and recurrence-free survival) were assessed. RESULTS: A total of 895 patients were included for study. On multivariable analysis, operative times were 30-40 minutes longer in procedures assisted by junior residents as compared to more senior trainees. Notably, trainee level was not associated with overall or severe complications on multivariable analyses. Similarly, trainee level was not associated with oncologic outcomes. CONCLUSION: While cases assisted by junior residents had longer operative times, complication rates and oncological outcomes were comparable across trainee groups. Trainee level does not appear to have an impact on perioperative and oncological outcomes of RC for urothelial carcinoma.
