CHOREOGRAPHED EXPANSION OF SERVICES RESULTS IN DECREASED PATIENT BURDEN WITHOUT COMPROMISE OF OUTCOMES: AN ASSESSMENT OF THE ONTARIO EXPERIENCE

Neuro-oncology care in Ontario has been historically centralized, at times requiring significant travel on the part of patients. Toward observing the goal of patient-centred care and reducing patient burden, two additional regional cancer centres (RCC) capable of neuro-oncology care delivery were introduced in 2016. This study evaluates the impact of increased regionalization of neuro-oncology services on healthcare utilization and travel burden for glioblastoma (GBM) patients in Ontario. We present a cohort of GBM patients diagnosed between 2010-2019. Incidence of GBM and treatment modalities were identified using provincial health administrative databases. A geographic information system and spatial analysis were used to estimate travel time from patient residences to neuro-oncology RCCs. Among the 5242 GBM patients, 79% received radiation as part of treatment. Median travel time to the closest RCC was higher for patients who did not receive radiation as part of treatment than for patients who did (p=0.03). After 2016, the volume of patients receiving radiation at their local RCC increased from 62% to 69% and median travel time to treatment RCCs decreased (p=0.0072). The two new RCCs treated 35% and 41% of patients within their respective catchment areas. Receipt of standard of care, surgery, and CRT, increased by 11%. Regionalization resulted in changes in the health care utilization patterns in Ontario consistent with decreased patient travel burden for patients with GBM. Focused regionalization did not come at the cost of decreased quality of care, as determined by delivery of a standard of care.
