Population-based determinants of radical prostatectomy operative time

Area of Science:

• Urology
• Surgical Oncology
• Health Services Research

Background:

• Operative time is a critical metric for assessing surgeon proficiency and quality of care in radical prostatectomy (RP).
• Understanding factors influencing operative times is essential for optimizing surgical training and resource allocation.

Purpose of the Study:

• To identify patient, surgeon, and hospital-related factors affecting operative times for robot-assisted radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP).
• To analyze trends in operative times for RARP and RRP over a defined study period.

Main Methods:

• A population-based observational cohort study utilized SEER-Medicare linked data from 2003-2009.
• Included 3458 men undergoing RARP and 6993 men undergoing RRP for prostate cancer.
• Median regression analysis was employed to assess factors influencing operative times.

Main Results:

• Median RARP operative time decreased by 68 minutes (315 to 247 min) from 2003 to 2008-2009 (P < 0.001), while RRP times remained constant (195 vs 197 min, P = 0.90).
• RARP was associated with longer operative times compared to RRP (PE 70.9, P < 0.001).
• Higher surgeon volume correlated with shorter operative times (P < 0.001), while obesity increased operative time (PE 15, P < 0.001).

Conclusions:

• RARP operative times significantly improved during the study period, whereas RRP times showed no change.
• Increased surgeon volume is a key factor in reducing operative time, potentially leading to substantial annual cost savings of nearly $15 million.
• Optimizing surgeon volume and efficiency could enhance resource utilization in prostatectomy procedures.
