[Adherence to antiplatelet and statin therapy by patients with acute coronary syndrome following discharge].

OBJECTIVE: To assess levels of medication adherence to antiplatelet and statins therapy among acute coronary syndrome (ACS) patients 30 days after hospital discharge and identify the main barriers to medication adherence and the main sociodemographic and clinical variables associated with treatment adherence.

METHOD: This was a quantitative longitudinal study. Patients admitted to hospital with ACS were included. Initially, data collection was conducted using a semi-structured interview during the hospital stay. Thirty days after hospital discharge, the Brief Medication Questionnaire was applied by phone to assess treatment adherence. Descriptive statistics were used and tests were applied to analyze the association between medication adherence and clinical and sociodemographic data.

RESULTS: One hundred and sixty-two patients were assessed. The Brief Medication Questionnaire test showed that 49.3% presented probable low adherence to treatment. Marital status, household income and alcohol intake showed an association with medication adherence.

CONCLUSIONS: The findings of the present study indicate high rates of probable nonadherence to medication among ACS patients 30 days after hospital discharge, this information could help nurses to choose specific nursing interventions that could improve adherence in patients' daily routines.
