Document Details : Title: Education is critical for medication adherence in patients with coronary heart disease Author(s): S. Zhao , H. Zhao , L. Wang , S. Du , Y. Qin Journal: Acta Cardiologica Volume: 70 Issue: 2 Date: 2015 Pages: 197-204 DOI: 10.2143/AC.70.2.3073511 Abstract : Background: Although non-adherence to medications is associated with increased cardiovascular risks, very little information is focused on the relationship between knowledge and medication adherence among patients with coronary heart disease (CHD). Aim: The purposes were to assess the relationship between medication adherence and medication- or disease-related knowledge in patients with CHD, and to investigate whether educating patients would alter their medication adherence behaviour. Methods: This study was carried out at the outpatient clinic of a public university teaching hospital in China. The primary outcome was the ability of patients to follow medication instructions, which was assessed by the Morisky Medication Adherence Scale (MMSA-8©). The Medication- or Disease-Related Knowledge Test (MDRKT) was used to assess patients’ medication-related knowledge. We also explored patients’ preferences for receiving education about medications and whether it is necessary for pharmacists to provide education. Results: Among the 159 patients who completed the survey, approximately 38.4% were considered non-adherent (MMAS-8© score < 6). Medicationor disease-related knowledge and concerns about adverse drug events were significantly associated with non-adherence. The MDRKT revealed that most participants had very little knowledge about their drug treatment. Specifically, 22 participants said that pharmacists were their primary source of information. Subsequently, 95.0% of participants expressed an interest in activities related to medication education. Conclusions: Knowledgeable patients with CHD are more likely to adhere to medication instructions. Many patients have difficulty acquiring medication information; thus, patients need increased access to education about their medication. Pharmacist services may be required to provide such information. |
