BACKGROUND: This study aimed to use administrative data (AD) linked to the Victorian death index (VDI) to report on overall long-term survival following colorectal cancer (CRC) surgery, comparing regional to metropolitan hospitals. METHODS: A retrospective cohort study using prospectively gathered AD linked to VDI. The primary outcome was overall survival (OS). Outcomes were adjusted for potential confounders via multivariable Cox proportional hazard regression analysis. RESULTS: Total of 17 533 patients: 12 879 metropolitan patients, 3835 inner regional patients and 719 outer regional patients.
