BACKGROUND: Institutions providing care to individuals with cancer are organized based on available resources and treatments offered. It is presumed that increasing levels of care will result in improved quality of care and outcomes. The objective is to determine whether Cancer Level Designation is associated with guideline adherent care and/or survival. METHODS: This is a retrospective study of individuals within the Ontario Rectal Cancer Cohort, a population-level database including all adults undergoing surgical resection for rectal cancer between 2010 - 2019 were included in Ontario, Canada. The primary exposure was Cancer Centre Level Designation as defined by Cancer Care Ontario (i.e., Level 1/2 = regional cancer center; Level 3 = affiliate cancer center; Level 4 = satellite cancer center). The primary outcomes were guideline adherent care and survival. Associations were determined using one-way analysis of variances and a multivariable Cox proportional hazards model. RESULTS: 12,399 patients were included with 54 % from a Level 1/2 centre, 33 % from a Level 3 centre and 13 % from a Level 4+ centre. All assessed aspects of guideline adherent care were associated with cancer centre level designation. Unadjusted 5-year overall survival was associated with cancer centre level designation (Level 1/2 79.5 % vs. Level 3 79.1 % vs. Level 4/non-designated 75.4 %, P = 0.003). Adjusted Cox Proportional Hazard Analysis for overall survival found the following: Level 4/5 HR 1.11 (95 %CI 0.99 - 1.25); Level 3 HR 1.01 (95 % CI 0.93 - 1.11); Level 1/2 1 [Referent group]. CONCLUSIONS: Increasing Cancer Centre Level Designation was associated with higher likelihood of receiving the appropriate investigations and treatments in those with rectal cancer and may also be associated with survival. POLICY SUMMARY: Future work should consider the centralization of complex rectal cancer care as well as quality improvement initiatives aimed at enhancing guideline adherent care across all centres managing rectal cancer.
