Background: Prospective data collection for perioperative outcomes might increase awareness of surgical results obtained for patients with prostate cancer (PCa) undergoing robot-assisted radical prostatectomy (RARP). This would prompt the implementation of measures aimed at reducing the risk of adverse outcomes. Objective: To assess the efficacy of an audit and feedback process aimed at identifying the most common complications after RARP and at implementing measures to improve outcomes. Design, setting, and participants: Overall, 415 patients treated with RARP by a high-volume surgeon were included. Perioperative outcomes for 187 patients treated between September 2016 and December 2017 were prospectively collected at 30 d according to the European Association of Urology guideline recommendations (group 1). An audit and feedback process was implemented in January 2018 whereby the most common complication (anastomotic leak) was identified and measures aimed at improving outcomes (changes in the anastomotic technique) were implemented. The outcomes for group 1 were then compared to 228 patients treated after implementation of the modified surgical technique (group 2). Surgical procedure: A novel technique for posterior reconstruction and urethrovesical anastomosis was introduced. Measurements: Perioperative outcomes included blood loss, operative time, length of stay, and 30-d postoperative complications. Logistic regression models tested the effect of the novel surgical technique on anastomotic leaks. Results and limitations: Overall, 97 patients (23%) experienced postoperative complications at 30 d. The rate of anastomotic leaks was significantly lower in group 2 compared to group 1 (3.1% vs 9.6%; p < 0.01). Similarly, overall and Clavien-Dindo grade ≥2 complication rates were lower in group 2 versus group 1 (17% vs 31%, and 6% vs 20%; both p ≤ 0.001). In multivariable analyses, treatment after implementation of changes in the anastomotic technique independently predicted a lower risk of complications (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.38–0.89) and of anastomotic leaks (OR 0.43, 95% CI 0.17–0.97). The lack of randomization represents the main limitation. Conclusions: Implementation of changes in the urethrovesical anastomosis technique arising from increased awareness of surgical outcomes reduced the risk of anastomotic leaks. These findings highlight the importance of audit and feedback processes using a standardized method for reporting surgical morbidity. Patient summary: Increased awareness of surgical outcomes prompted us to change our technique for connecting the bladder to the urethra during robot-assisted surgery to remove the prostate in patients with prostate cancer. These changes resulted in significant improvements in surgical outcomes.

Abstract
Background: Prospective data collection for perioperative outcomes might increase awareness of surgical results obtained for patients with prostate cancer (PCa) undergoing robot-assisted radical prostatectomy (RARP). This would prompt the implementation of measures aimed at reducing the risk of adverse outcomes. Objective: To assess the efficacy of an audit and feedback process aimed at identifying the most common complications after RARP and at implementing measures to improve outcomes. Design, setting, and participants: Overall, 415 patients treated with RARP by a high-volume surgeon were included. Perioperative outcomes for 187 patients treated between September 2016 and December 2017 were prospectively collected at 30 d according to the European Association of Urology guideline recommendations (group 1). An audit and feedback process was implemented in January 2018 whereby the most common complication (anastomotic leak) was identified and measures aimed at improving outcomes (changes in the anastomotic technique) were implemented. The outcomes for group 1 were then compared to 228 patients treated after implementation of the modified surgical technique (group 2). Surgical procedure: A novel technique for posterior reconstruction and urethrovesical anastomosis was introduced. Measurements: Perioperative outcomes included blood loss, operative time, length of stay, and 30-d postoperative complications. Logistic regression models tested the effect of the novel surgical technique on anastomotic leaks. Results and limitations: Overall, 97 patients (23%) experienced postoperative complications at 30 d. The rate of anastomotic leaks was significantly lower in group 2 compared to group 1 (3.1% vs 9.6%; p < 0.01).
