INTRODUCTION AND OBJECTIVES: Observational studies have shown that oral anticoagulants (OAC) prescription is suboptimal in patients with nonvalvular atrial fibrillation (NVAF). Our objective was to evaluate the usefulness of a prospective protocol for increasing OAC usage in these patients. PATIENTS AND METHOD: From 1 February 2000 until 31 October 2002 we enrolled all patients with chronic NVAF seen in two outpatient cardiology clinics, excluding candidates for cardioversion. Each patient was studied to identify cardioembolic risk factors (CERF) and contraindications for OAC. Anticoagulation was suggested to all patients with > or =2 CERF and without contraindications for OAC. The decision to prescribe OAC was made by the physician in charge when there was only one CERF. RESULTS: 721 patients fulfilled the inclusion criteria. Mean age was 73 +/- 8 years; 44% were men. In most cases NVAF was related with hypertension (57%), followed by no structural heart disease (25%) or ischemic heart disease (9%). The most frequent CERFs were hypertension (66%), age > or =75 years (45%) and diabetes (24%). A total of 663 patients had > or =1 CERF (92%), and 125 (19%) of these presented at least one contraindication for OAC. Of the 538 remaining patients (90%), 485 (67% of the whole series) were treated with anticoagulation. Of the patients with > or =2 CERF and without contraindications for OAC, 95% were treated. CONCLUSIONS: A prospective protocol for use in the outpatient cardiology clinic allows to prescribe OAC in a large percentage of patients with NVAF.
