Optimal Cystectomy Outcome: A Composite Measurement Evaluating Quality of Care and Mortality Benefit

      OBJECTIVES

      To evaluate the incidence and impact of an “optimal cystectomy outcome” (OCO), a simplified performance metric that encompasses multiple patient-centered outcomes.

      METHODS

      We identified patients in the National Cancer Center Database undergoing radical cystectomy for stage cT2-cT3 urothelial carcinoma (2006-2014). OCO was defined as negative resection margin, adequate lymphadenectomy (>10 nodes), no prolonged length-of-stay (<75th percentile), no 30-day-readmission, and no 30-day-mortality. We used multivariable logistic regression and Cox proportional-hazards models to identify factors associated with OCO and overall survival (OS).

      RESULTS

      Among 12,997 patients who fit the inclusion criteria, individual OCO components were attained at a relatively high rate; however, only 37.6% of patients met all 5 OCO criteria. Patients who underwent surgery at a high-volume (OR 2.45) academic facility (OR 1.60) using a minimally-invasive approach (OR 1.32) were more likely to receive an OCO. Patients were less likely to receive an OCO if they were older (OR 0.98), African American (OR 0.71), had Medicaid insurance (OR 0.66), or more comorbidities (OR 0.48) (all P <0.05). Patients who received an OCO were found to have a significantly lower risk of overall mortality (HR 0.69, P <0.05).

      CONCLUSION

      Various patient- and hospital-specific factors affect a system's ability to achieve OCO in patients undergoing radical cystectomy. OCO is directly associated with improved OS and has the potential to function as a composite performance metric for the quality of care in bladder cancer.
