A Multi-Center International Study Assessing the Impact of Differences in Baseline Characteristics and Perioperative Care Following Radical Cystectomy.

ABSTRACT: Background: To identify potential avenues for quality improvement, we compared the variations in clinical practice and their association with perioperative morbidity and mortality following radical cystectomy (RC) for bladder cancer in the United States (US) and Japan. Methods: We reviewed our retrospectively collected database of 2240 patients who underwent RC for bladder cancer at the University of Michigan (n?=?1427) and in 21 Japanese institutions (n?=?813) between 1997 and 2014. We performed a systematic comparison of clinical and perioperative factors and assessed predictors of perioperative morbidity and mortality. Death within 90 days of surgery was the primary outcome. Results: There were apparent differences between the two study populations. Notably, US patients had a significantly greater BMI and higher ASA score. In Japanese institutions, median postoperative hospital stay was significantly higher (40 days vs. 7 days, p?< ?0.001) and 90-day readmission rates were significantly lower (0.6% vs. 26.8% , p?< ?0.001). There was a total of 1372/2240 (61.2%) patients with complications within 90 days and 66/2240 (2.9%) patient deaths. Significant predictors of 90-day mortality were older age (OR 1.04, CI 1.01-1.07), higher body mass index (OR 1.07, CI 1.02-1.12), node-positive disease (OR 3.14, CI 1.78-5.47), increased blood loss (OR 1.02, CI 1.01-1.03), and major (Clavien-grade 3 or greater) complication (OR 3.29, CI 1.88-5.71). Conclusion: Despite major differences in baseline characteristics and care of cystectomy patients between the two study populations, peri-operative mortality rates proved to be comparable. This data supports an exploration of non-traditional factors that may influence mortality after cystectomy.

Project description:BACKGROUND AND OBJECTIVES:The use of patient-controlled epidural analgesia after various operations has been associated with an early return of bowel function, thus decreasing patients' length of stay (LOS). The primary aim of this study was to compare LOS after radical cystectomy between patients who received epidural analgesia versus those who received intravenous patient-controlled analgesia. Our secondary analysis included the assessment of other metrics such as total opioid requirements, pain scores, return of bowel function, and complication rates between the 2 groups. METHODS:We conducted a retrospective review using the electronic medical records of 308 patients who underwent radical cystectomies at Memorial Sloan Kettering between 2006 and 2011. We aimed to understand if epidural analgesia was associated with a reduced LOS compared with patient-controlled intravenous opioid analgesia. We also aimed to identify performance improvements as a function of epidural analgesia status using various metrics such as pain management, bowel function return, and complication rates. We used both univariate and multivariate analyses to identify if epidural analgesia was associated with meaningful differences in the aforementioned metrics. RESULTS:Median age at radical cystectomy, body mass index, sex, American Society of Anesthesiologists score, and T stage were similar for both groups. For our primary objective of LOS, we found no significant difference between the 2 cohorts (8 vs 7 days, P = 0.2). Analysis of our secondary outcome measures revealed that epidural analgesia use was associated with less total opioid requirement for the first 3 postoperative days (PODs) (P = 0.0001). In addition, epidural analgesia was found to be associated with improved postoperative pain scores compared with intravenous patient-controlled analgesia on PODs 1 (P = 0.0001) and 2 (P = 0.004), and there was a slight improvement on POD 3, but this was not significant (P = 0.77). In contrast, we found no difference between pain management types with regard to proportion of patients who experienced a delay in gastrointestinal recovery, fluid bolus requirements within the first 3 perioperative days, rates of infection, pulmonary complications, and grade 3 or greater complications. CONCLUSIONS:We have demonstrated that, despite significant improvements in initial pain control and less opioid requirement with patient-controlled epidural analgesia, there was no association between analgesic approach and LOS, return of bowel function, or complications.
