SARS-CoV-2 strained Ontarios health system, with social determinants of health (SDH) underexplored in cost analyses. We examined COVID-19 attributable healthcare resource use and costs from the Ontario health system perspective using health administrative data. We conducted a cohort study, matching 162,633 SARS-CoV-2-exposed individuals 1:1 to unexposed individuals. We calculated 10-day per-person mean attributable costs (2023 CAD) across care phases (pre-diagnosis, acute, post-acute, terminal), stratified by individual and area-level SDH. Among exposed individuals (mean age 40.4 years, 50.7% female), 6% were hospitalized, 1.3% admitted to critical care, and 2% died within 360 days. Mean (SD) person acute phase cost was $244 ($235-$253) and higher among males, recent immigrants, individuals living in low-income neighbourhoods and neighbourhoods with a higher proportion of crowded households. Extrapolating to the population level of 166,801 exposed individuals, the mean total survival-adjusted 360-day cost was $436 million. COVID-19 increased healthcare costs, disproportionately burdening marginalized communities.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
