OBJECTIVE: To develop quality assessment tool to evaluate surgical performance for robot-assisted radical cystectomy program.

METHODS: A prospectively maintained quality assurance database of 425 consecutive robot-assisted radical cystectomies performed by a single surgeon between 2005 and 2015 was retrospectively reviewed. Potentially modifiable factors, related to the management and perioperative care of patients, were used to evaluate patient care. Criteria included the following: preoperative (administration of neoadjuvant chemotherapy); operative (operative time \<6.5 hours and estimated blood loss \<500 cc); pathologic (negative soft tissue surgical margins and lymph node yield >=20); and postoperative (no high-grade complications, readmission, or noncancer-related mortality within 30 days).The Quality Cystectomy Score (QCS) was developed (1 star: achieving <=2 criteria or mortality within 30 days; 2 stars: 3 or 4 criteria met; 3 stars: 5 or 6 criteria met; and 4 stars: 7 or all criteria met). Univariate and multivariate Cox proportional hazard regression models were fitted to test for the association between QCS and survival outcomes.

RESULTS: Most patients (85\%) achieved at least 3 stars, and more patients achieved 4 stars with time. High QCS was associated with better recurrence-free, cancer-specific, and overall survival (P values \<.05). None of the patients with 1-star were alive at 1 year. Patients with 4 stars achieved the best survival rates (recurrence-free survival [62\%], cancer-specific survival [70\%], and overall survival [53\%] at 5 years) (log rank P \< .0001).

CONCLUSION: Continuous assessment for quality improvement facilitated implementation and maintenance of robot-assisted program for bladder cancer.
