Choreographed expansion of services results in decreased patient burden without compromise of outcomes: An assessment of the Ontario experience.

Background: Neuro-oncology care in Ontario, Canada has been historically centralized, at times requiring significant travel on the part of patients. Toward observing the goal of patient-centered care and reducing patient burden, 2 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, from 11 to 13 oncology centers, on healthcare utilization and travel burden for glioblastoma (GBM) patients in Ontario.

Methods: We present a cohort of GBM patients diagnosed between 2010 and 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.

Results: 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 = .03). After 2016, the volume of patients receiving radiation at their local RCC increased from 62% to 69% and the median travel time to treatment RCCs decreased (P = .0072). The 2 new RCCs treated 35% and 41% of patients within their respective catchment areas. Receipt of standard of care, surgery, and chemoradiation (CRT), increased by 11%.

Conclusions: Regionalization resulted in changes in the healthcare 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 the delivery of a standard of care.
