Abstract:
OBJECTIVE:To assess the relative contributions of patient and surgeon factors for predicting selection of ileal conduit (IC), neobladder (NB), or continent pouch (CP) urinary diversions (UD) for patients diagnosed with muscle-invasive/high-risk nonmuscle invasive bladder cancer. This information is needed to enhance research comparing cancer survivors' outcomes across different surgical treatment options. METHODS:Bladder cancer patients' age ≥21 years with cystectomy/UD performed from January 2010 to June 2015 in 3 Kaiser Permanente regions were included. All patient and surgeon data were obtained from electronic health records. A mixed effects logistic regression model was used treating surgeon as a random effect and region as a fixed effect. RESULTS:Of 991 eligible patients, 794 (80%) received IC. One hundred sixty-nine surgeons performed the surgeries and accounted for a sizeable proportion of the variability in patient receipt of UD (intraclass correlation coefficient = 0.26). The multilevel model with only patient factors showed good fit (area under the curve = 0.93, Hosmer-Lemeshow test P = .44), and older age, female sex, estimated glomerular filtration rate <45, 4+ comorbidity index score, and stage III/IV tumors were associated with higher odds of receiving an IC vs neobladder/continent pouch. However, including surgeon factors (annual cystectomy volume, specialty training, clinical tenure) had no association (P = .29). CONCLUSION:In this community setting, patient factors were major predictors of UD received. Surgeons also played a substantial role, yet clinical training and experience were not major predictors. Surgeon factors such as beliefs about UD options and outcomes should be explored.
