Post-acute health care costs following SARS-CoV-2 infection: A retrospective cohort study of among 531,182 matched adults

Abstract

AbstractPost-acute health care costs following SARS-CoV-2 infection are not known. Beginning 56 days following SARS-CoV-2 polymerase chain reaction (PCR) testing, we compared person-specific total and component health care costs across their distribution for the following year (test-positive versus test-negative, matched people; January 1, 2020-March 31, 2021). For 531,182 individuals, mean person-specific total health care costs were $513.83 (95% CI $387.37-$638.40) higher for test-positive females and $459.10 (95% CI $304.60-$615.32) higher for test-positive males, or >10% increase in mean per-capita costs, driven by hospitalization, long-term care, and complex continuing care costs. At the 99thpercentile of each subgroup, person-specific health care costs were $12,533.00 (95% CI $9,008.50-$16,473.00) higher for test-positive females and $14,604.00 (95% CI $9,565.50-$19,506.50) for test-positive males, driven by hospitalization, specialist (males), and homecare costs (females). Cancer costs were lower. Six-month and 1-year costs differences were similar. These findings can inform planning for post-acute SARS-CoV-2 health care costs.
