A new analysis published in JAMA Network Open quantifies the economic burden atrial fibrillation places on the commercial insurance system and employers. A cross-sectional study of more than 1.6 million privately insured employees found that AF is associated with $11,393 in excess annual medical costs per person and an additional $840 in productivity losses due to sick leave and short-term disability.
Researchers from the CDC and collaborating institutions analyzed 2021 MarketScan Commercial Claims data linked to employer-reported absence records. After adjusting for demographics and comorbidities, outpatient care emerged as the dominant cost driver, accounting for $7,059 in excess spending for services and $1,875 for prescriptions. This represents a notable shift from earlier studies, in which inpatient costs predominated, likely reflecting the expanded use of direct oral anticoagulants, catheter ablation procedures, and remote monitoring in ambulatory settings.
The study identified meaningful sex-based differences in the distribution of costs. Women with AF incurred higher emergency department and inpatient costs than men, potentially reflecting documented disparities in treatment intensity and diagnostic delays that result in more acute episodes. Rural-urban differences were minimal except for lower pharmacy costs among rural residents.
For managed care organizations, these findings underscore the value of outpatient benefit design and access to specialty care in managing AF populations. The productivity data, which indicate nearly four additional missed workdays annually among employees with AF, may also inform employer wellness initiatives and workplace accommodations to reduce AF-related disruptions.
