Cost analysis and economic evaluation of a virtual pediatric emergency department pilot program.

Objectives: The Children's Hospital of Eastern Ontario launched Canada's first virtual pediatric emergency department (ED) from May 2020 through November 2021 to deliver accessible care during the COVID-19 pandemic. The objective of this study was to (i) conduct a cost analysis of the virtual pediatric ED, and (ii) compare the virtual costs to in-person ED costs to inform future resource allocation decisions.

Methods: We calculated costs from a health system perspective in 2021 Canadian dollars. Using a decision tree model, we compared expected costs with and without the virtual pediatric ED, and calculated overall and per patient cost savings of implementing the virtual ED.

Results: The virtual ED provided care to 7394 patients. In the base case, virtual care saved $890,000 ($120 per patient). One-way sensitivity analyses suggest overall cost savings were most sensitive to the proportion of virtual care patients who would have received in-person care had the virtual option not been available (range $300,000-$1,700,000), followed by ED overhead costs (range $640,000-$1,140,000). Multivariate sensitivity analyses demonstrated robust cost savings of $920,000 (95% CI 850,000-990,000) in a scenario using billing codes to calculate costs, and savings of $1,040,000 (95% CI 960,000-1,120,000) if physician salaries were used instead.

Conclusions: These findings suggest the virtual pediatric ED reduced costs per patient. Virtual care may represent a financially valuable pediatric emergency department service.
