Abstract The main objective of this study is to measure health literacy in patients treated with oral anticoagulants and their knowledge about their treatment, and to analyze the relationships between health literacy, knowledge of their treatment, adherence, the occurrence of adverse drug reactions and several demographic and socioeconomic factors. The studied population consisted of patients going to a pharmacy with a medical prescription for oral anticoagulants. We used the abbreviated questionnaire of the European Project of Health Literacy HLS-EU-Q16 to measure health literacy and structured interviews in order to measure general knowledge about the treatment. From 133 patients in treatment with anticoagulants, 49.6% were male and the mean age was 69.72 ± 12.66 years. The levels of health literacy were in accordance with those reported by recent literature, with 51.1% of the sample having an adequate level of health literacy, 33.8% a problematic level and 15% an insufficient level. One in two patients had limited health literacy. Health literacy levels and patient knowledge were poor, and there was a relationship between them. Both decrease with age and increase with formal educational level and perceived socioeconomic status. We found no relationship between self-reported compliance or self-reported complications and health literacy or knowledge. Strategies should be implemented to promote empowerment, especially in chronic patients and those populations with fewer competencies in health information management.
