The aim of this study was to estimate the extent to which work-related injuries contribute to medical expenditures paid for by group health insurance.Administrative data on OSHA recordable injuries spanning 2010 to 2013 were obtained for female patient care workers (n = 2495). Expenditures were aggregated group health insurance claims for 3 and 6-month periods before/after injury. Group health insurance plan type, age group, and job category were control variables.Being injured is associated with the odds of having expenditures at both 3 months, odds ratio (OR) 2.17 [95% confidence interval (95% CI) 1.61 to 2.92], and 6 months, 2.95 (95% CI 1.96 to 4.45). Injury was associated with $275 of additional expenditures (95% CI $38 to $549) over 3 months and $587 of additional expenditures (95% CI $167 to $1140) over 6 months.Injury was associated with increased odds of positive expenditures and increased expenditures paid for by group health insurance.
