Patients with higher Elderly Risk Assessment index (ERA) scores, a surrogate for health vulnerability, received anticoagulation less often than patients with lower scores. The percentage of patients with a history of falling was higher among those who did not receive anticoagulation than among those who did (44.4% vs 32.8%; P\u2009&lt;\u2009.001). Similarly, a diagnosis of dementia was more common in the no-anticoagulation group than the anticoagulation group (18.5% vs 12.7%; P\u2009&lt;\u2009.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>A substantial proportion of older adults with AF\/F do not receive anticoagulation. Those without anticoagulation had higher risk of health deterioration based on higher ERA scores and had a higher incidence of dementia and fall history.
