Abstract
AIMS AND OBJECTIVES: To compare drug adherence to lipid-lowering therapy among outpatients with coronary artery disease who received information via short message service, via short message service and Micro Letter, or via phone only. BACKGROUND: Messaging applications and short message service are commonly used internationally. However, little is known about how coronary artery disease outpatients in China may benefit from receiving health education through these technologies. DESIGN: Random sampling method. METHODS: Data were collected from March-December 2013. Subjects from Chengdu City, China, were randomised to three groups: short message service, short message service + Micro Letter, and phone (control). Appointment reminders and health information were delivered to patients in accordance with designations. After six months, adherence to statin prescriptions was compared among the groups by using the Morisky Medication Adherence Scale. Logistic regression analysis was applied to determine those independent variables that were related to adherence. RESULTS: The short message service and short message service + Micro Letter groups had better cumulative adherence (lower Morisky Medication Adherence Scale scores) after six months than phone group, and the short message service + Micro Letter group had better cumulative adherence (lower Morisky Medication Adherence Scale scores) than the short message service group. Female sex, older age and marriage show positive associations with adherence. CONCLUSIONS: Short message service and messaging applications, such as Micro Letter, are effective means of providing discharged patients with reminders and coronary artery disease-related health information. Implementation of a short message service + Micro Letter program can improve outpatient adherence to medication. RELEVANCE TO CLINICAL PRACTICE: This research offers useful information to help medical staff design effective interventions to improve medication compliance among coronary artery disease patients.
