Surgeon fatigue: impact of case order on perioperative parameters and patient outcomes.

Purpose: We tested the hypothesis that surgeon fatigue results in worse outcomes for laparoscopic and robot-assisted laparoscopic prostatectomy, and percutaneous nephrolithotomy by comparing outcomes of sequentially scheduled procedures.

Materials And Methods: We identified days when 2 procedures of the same type were performed by the same surgeon, including 72 laparoscopic and 340 robot-assisted laparoscopic prostatectomies, and 110 percutaneous nephrolithotomies. Clinical data and outcomes were compared.
