ObjectiveTo analyse the impact of centralisation of radical cystectomy (RC) provision for bladder cancer in England, on postoperative mortality, length of stay (LoS), complications and re-intervention rates, from implementation of centralisation from 2003 until 2014. In 2002, UK policymakers introduced the 'Improving Outcomes Guidance' (IOG) for urological cancers after a global cancer surgery commission identified substantial shortcomings in provision of care of RCs. One key recommendation was centralisation of RCs to high-output centres. No study has yet robustly analysed the changes since the introduction of the IOG, to assess a national healthcare system that has mature data on such institutional transformation.Patients And MethodsRCs performed for bladder cancer in England between 2003/2004 and 2013/2014 were analysed from Hospital Episode Statistics (HES) data. Outcomes including 30-day, 90-day, and 1-year all-cause postoperative mortality; median LoS; complication and re-intervention rates, were calculated. Multivariable statistical analysis was undertaken to describe the relationship between each surgeon and the providers' annual case volume and mortality.ResultsIn all, 15 292 RCs were identified. The percentage of RCs performed in discordance with the IOG guidelines reduced from 65% to 12.4%, corresponding with an improvement in 30-day mortality from 2.7% to 1.5% (P = 0.024). Procedures adhering to the IOG guidelines had better 30-day mortality (2.1% vs 2.9%; P = 0.003) than those that did not, and better 1-year mortality (21.5% vs 25.6%; P < 0.001), LoS (14 vs 16 days; P < 0.001), and re- intervention rates (30.0% vs 33.6%; P < 0.001). Each single extra surgery per centre reduced the odds of death at 30 days by 1.5% (odds ratio [OR] 0.985, 95% confidence interval [CI] 0.977-0.992) and 1% at 1 year (OR 0.990, 95% CI 0.988-0.993), and significantly reduced rates of re-intervention.ConclusionCentralisation has been implemented across England since the publication of the IOG guidelines in 2002. The improved outcomes shown, including that a single extra procedure per year per centre can significantly reduce mortality and re-intervention, may serve to offer healthcare planners an evidence base to propose new guidance for further optimisation of surgical provision, and hope for other healthcare systems that such widespread institutional change is achievable and positive.© 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.
