Note. Average SVI score indicates fractional rank among all 810 US counties.
B indicates non-Hispanic black; DCEA, distributional cost-effectiveness analysis; H, Hispanic; Q, quintile (1= least socially vulnerable; 5 = most socially vulnerable); SVI, social vulnerability index; W, non-Hispanic white.
Inpatient mortality adjustor: the difference between the subgroup SVI and the national sample SVI was used to create an adjustment factor for the baseline risk of COVID-19 inpatient mortality, based on the 13.7% increase per 0.1-point increase in SVI, per Karmakar et al3 (based on data from March 25 to June 29, 2020).
Unadjusted COVID-19 hospitalization rate: estimated rate of hospitalization based on the number of patients in the subgroup and the age distribution of patients within the subgroup, per Reese et al28 based on data from February 27 to September 30, 2020 (see Appendix in Supplemental Materials found at https://doi.org/10.1016/j.jval.2022.08.010 for detail on demographics based on subgroup).
SVI-adjusted COVID-19 hospitalization rate: estimated rate of hospitalization based on adjustments to baseline rate to reflect 14.3% increase in COVID-19 hospitalizations for every 0.1-point increase in SVI (relative to the national average SVI), per Karmakar et al.3
