An employer perspective on annual employee and dependent costs for pediatric asthma

Abstract

The burden of pediatric asthma on parents' health care costs is not well described. To evaluate direct and indirect health care costs of employees with children with asthma (asthma cohort) compared with employees with children without asthma (control cohort). Retrospective analysis of 2001-2007 employer data including employee medical and pharmacy claims, payroll, work absence, demographics, and dependent medical and pharmacy claims. Asthma diagnosis or pharmacy claims for asthma controller medications were used to identify employees with dependents younger than 12 years for the asthma cohort. Controls were identified based on dependent age and lack of an asthma diagnosis or pharmacy claim for a controller medication. All costs were calculated using 2-part regression models that controlled for demographics, job information, Charlson Comorbidity Index, and region. Costs were calculated for employee health care, prescriptions, sick leave, short- and long-term disability, and workers' compensation and dependent health care and prescriptions. Costs were compared for employees with children aged 0 through 3 years, 4 through 7 years, 8 through 11 years, and younger than 12 years. Data were available for 11,794 asthma cohort employees and 64,812 controls. Statistically significant annual cost differences were identified for employee health care ($154, P < .001), prescriptions ($95, P < .001), sick leave (-$41, P < .001), short-term disability (-$41, P = .008), dependent health care ($862, P < .001), and prescriptions ($534, P < .001). Pediatric asthma is associated with significant additional health care and prescription costs for both employees and dependents.
