Trends in Healthcare Expenditures and Incremental Healthcare Cost in Adults with Atrial Fibrillation in the United States

Abstract

BackgroundAtrial fibrillation (AF) is associated with increased healthcare costs; however, comprehensive data on the financial burden of AF remain limited. ObjectivesTo delineate healthcare expenditures among patients with AF. MethodsWe used the longitudinal panels from the Medical Expenditure Panel Survey (MEPS) covering 2016-2019 to estimate healthcare expenditures associated with AF. We identified individuals aged ≥18 with AF in the first year of each panel (2016-2018) using the ICD-10 code. Covariates included sociodemographic characteristics and comorbidities. Healthcare expenditures were derived from the second year of each panel (2017-2019) to reflect the cost of having the condition for an entire year. Adjusted mean annual costs were calculated, including total healthcare expenditure, hospital inpatient, emergency room visits, office based, outpatient visits, home health visits, prescribed medicines, and other expenses. Adjusted models were used to estimate the mean annual incremental total healthcare cost associated with AF. ResultsThe weighted study population included 3,080,055 adults with AF (382 respondents, mean age 71.5, 89.9% White). The adjusted annual total healthcare cost among adults with AF totaled $14,083 (95% CI, $10,887 – 17,279) compared to $8,771 (95% CI, $ 8,106 – 9,436) for those without AF. Primary drivers of cost over time were hospital inpatient care, office based visits, and prescribed medications. The annual incremental total healthcare cost associated with AF was $5,312 per adult (in 2019 US dollars). ConclusionAdults with AF in the US face a higher financial burden across various healthcare services compared to those without the condition, with consistently increasing expenses in inpatient care and prescribed medicines. Further research is needed to identify the independent contribution of AF to these costs.
