Background Adherence to prescribed drug therapy is associated with lower rates of cardiovascular causes of death. In view of the relevance for public health, it is important to understand the relation between medication adherence tools' scores, especially in low literacy patients discharged from a cardiology ward. Objectives We aimed to assess: (a) the association between number of controlled clinical conditions and adherence tools scores, and (b) the correlation between the scores of three instruments to assess adherence. Methods We conducted a prospective study and included patients discharged from a specialized cardiovascular ward in Brazil. The results of the Beliefs about Medicines questionnaire (BMQ), the Adherence to Refills and Medication Scale (ARMS) and the MedTake test were compared. Results Of 53 included patients, most of them were elderly, and did not complete primary school. On average, there were six health conditions per patient, where two of them were not controlled. ARMS was the only tool that was associated with number of controlled health conditions (r = -0.312, p < 0.05). Moreover, ARMS (average score 15.6 +/- 3.4) had significant correlation with MEDTAKE (r = 0.535, p < 0.01) and BMQ (r = 0.38, p < 0.01). BMQ and MEDTAKE were also positively correlated (r = 0.311, p < 0.05). Conclusions Clinically, higher ARMS scores (> 12) suggest assumed non-adherence. It is also negatively correlated with the number of controlled clinical conditions in low literacy elderlies with cardiovascular diseases.
