OBJECTIVES: To determine the level of control in treatment compliance in a sample of patients who were treated with acenocoumarol attended in Primary Care settings. MATERIAL AND METHODS: Cross-sectional study. Patients with non-valvular atrial fibrillation treated with acenocoumarol were included. The sample size was calculated based on previous studies. Data of patients who possessed International Normalized Ratio (INR) values in last 6 months in medical consult were collected. It was considered that the INR control was inadequate when the percentage of INR values within the therapeutic range was less than 60% in the last 6 months. Assessment of compliance by telephone interview was conducted by the Morisky-Green Test. RESULTS: One hundred and ninety-one patients, 110 women (57.6%) with an average age of 76.5±9.4 years were included. Seventy-six patients (39.8%) were in therapeutic range (INR: 2-3) and 115 patients (60.2%) were out of range (below 2 the 20.9% and above 3 the 39.3%). Poor control of INR increased to the age of 85 years (<75 years: 57.8%; 75-85 years: 67.6%;>85 years: 61.5%). Ninety patients responded to the compliance questionnaire (78.3%), being compliant 74 (82.2%) and non-compliant 16 (17.8%). CONCLUSIONS: Six of 10 patients undergoing treatment with acenocoumarol are out of range and nearly 2 of each 10 patients out of range does not accomplish the treatment. We call attention to the need to make a systematically review of adherence in anticoagulated patients attended in Primary Care settings.
