Abstract：Objective To assess compliance and instability of anticoagulation level in outpatients on oral anticoagulant therapy. Methods Five hundred and eighty three patients with nonvalvular atrial fibrillation from eight general hospitals and seven community health service centers which allocated in eight districts in Beijing city were questioned by physicians. Subjects who were prescribed warfarin treatment were followed up 2 times between March 2008 and April by telephone. Results One hundred and ten of these S83 patients(18.9%) and 85 of 466 patients(18.2% ) at high stroke risk took warfarin. Twenty nigh point two percent of patients achieved the therapeutic INR value in 3 months, and 44.7% achieved the INR target in 1 year. Eighty four of 105 patients(80% ) continue to take warfarin lyear later. Of those patients giving up treatment, 67. 8% of them stopped treatment within 6 months. Over 20% of patients monitored INR value at most once every 3 months. Conclusions The utility of anticoagulation treatment is low in outpatients with nonvalvular atrial fibrillation especially in patients at high stroke risk. The compliance of monitor is poor. Patient education should be done to increase the compliance of anticoagulation treatment.
