Direct and indirect costs of stroke associated with AF

Stroke associated with atrial fibrillation (AF-stroke) is associated with substantially higher total, acute hospital, nursing home, and general practitioner costs per patient, according to a study published recently in Stroke.1

In a population-based prospective study of incident and recurrent stroke treated in hospital and community settings, the authors investigated direct and indirect costs for a two-year period. Survival, disability, post-stroke residence, and healthcare use were determined at 90 days, one year, and two years. Acute hospital cost was determined using a case-mix approach, and other costs using a bottom-up approach (2007 prices).

In 568 patients ascertained in one year (2006), the total estimated two-year cost was $33.84 million. In the overall sample, AF-stroke accounted for 31% (177) of patients, but a higher proportion of costs (40.5% of total and 45% of nursing home costs). On a per-patient basis compared with non–AF-stroke, AF-stroke was associated with higher total (P<0.001) and acute hospital costs (P<0.001), and greater nursing home (P=0.001) and general practitioner (P<0.001) costs among 90-day survivors.

After stratification by stroke severity in survivors, AF was associated with a twofold increase in costs in patients with mild-moderate (National Institutes of Health Stroke Scale, 0–15) stroke (P<0.001) but not in severe stroke (National Institutes of Health Stroke Scale ≥16; P=0.7).

Targeted programmes to identify AF and prevent AF-stroke may have significant economic benefits, in addition to health benefits, say the authors.
