Incidence and Prevalence of Atrial Fibrillation and Associated Mortality Among Medicare Beneficiaries: 1993–2007
Open accessAbstract
Background—: Atrial fibrillation (AF) is a common and costly problem among older persons. The frequency of AF increases with age, but representative national data about incidence and prevalence are limited. We examined the annual incidence, prevalence, and mortality associated with AF among older persons. Methods and Results—: In a retrospective cohort study of Medicare beneficiaries 65 years and older diagnosed with AF between 1993 and 2007, we measured annual age- and sex-adjusted incidence and prevalence of AF and mortality following an AF diagnosis. Among 433 123 patients with incident AF, the mean age was 80 years, 55% were women, and 92% were white. The incidence of AF remained steady during the 14-year study period, ranging from 27.3 to 28.3 per 1000 person-years. Incidence rates were consistently higher among men and white beneficiaries. The prevalence of AF increased across the study period (mean, 5% per year) and was robust to sensitivity analyses. Among beneficiaries with incident AF in 2007, 36% had heart failure, 84% had hypertension, 30% had cerebrovascular disease, and 8% had dementia. Mortality after AF diagnosis declined slightly over time but remained high. In 2007, the age- and sex-adjusted mortality rates were 11% at 30 days and 25% at 1 year. Conclusions—: Among older Medicare beneficiaries, incident AF is common and has remained relatively stable for more than a decade. Incident AF is associated with significant comorbidity and mortality; death occurs in one-quarter of beneficiaries within 1 year.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
