COVID-19 Healthcare Costs and Utilization in Ontario, 2021-2023

1,321,174 COVID-19 cases from Ontario, Canada, were analyzed to quantify healthcare resource use and costs before and after infection. The study, authored by Chloe McDonald and published on figshare, compares outcomes by vaccination status using administrative health data from January 2021 to May 2023. Results show a significant increase in hospitalizations and ICU admissions post-infection, with vaccinated individuals exhibiting a smaller cost burden.

Use Cases

• Modeling the economic burden of COVID-19 based on healthcare cost data
• Comparing healthcare resource utilization trends between vaccinated and unvaccinated populations
• Analyzing temporal patterns in ICU admissions and hospitalizations post-infection

Strengths

• Analyzes a large cohort of 1,321,174 COVID-19 cases
• Provides specific cost figures (e.g., +CAD 5,838 to CAD 18,730 for vaccinated ICU costs)
• Covers a defined time range from January 1, 2021, to May 31, 2023
• Includes a direct comparison of outcomes by vaccination status

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is limited to Ontario, Canada, which may not be generalizable to other regions
