lüll Barriers to the use of anticoagulation for nonvalvular atrial fibrillation: a representative survey of Australian family physicians Gattellari M; Worthington J; Zwar N; Middleton SStroke 2008[Jan]; 39 (1): 227-30BACKGROUND AND PURPOSE: Anticoagulation reduces the risk of stroke in nonvalvular atrial fibrillation yet remains underused. We explored barriers to the use of anticoagulants among Australian family physicians. METHODS: The authors conducted a representative, national survey. RESULTS: Of the 596 (64.4%) eligible family physicians who participated, 15.8% reported having a patient with nonvalvular atrial fibrillation experience an intracranial hemorrhage with anticoagulation and 45.8% had a patient with known nonvalvular atrial fibrillation experience a stroke without anticoagulation. When presented with a patient at "very high risk" of stroke, only 45.6% of family physicians selected warfarin in the presence of a minor falls risk and 17.1% would anticoagulate if the patient had a treated peptic ulcer. Family physicians with less decisional conflict and longer-standing practices were more likely to endorse anticoagulation. CONCLUSIONS: Strategies to optimize the management of nonvalvular atrial fibrillation should address psychological barriers to using anticoagulation.|Anticoagulants/adverse effects/*therapeutic use[MESH]|Atrial Fibrillation/*complications[MESH]|Australia[MESH]|Health Care Surveys[MESH]|Hemorrhage/chemically induced[MESH]|Humans[MESH]|Medical Errors[MESH]|Patient Compliance[MESH]|Physicians, Family[MESH]|Physicians/*psychology[MESH]|Practice Guidelines as Topic[MESH]|Practice Patterns, Physicians'/*statistics & numerical data[MESH]|Risk Factors[MESH]|Stroke/*etiology/*prevention & control[MESH]|Warfarin/adverse effects/therapeutic use[MESH] |
