Abstract
OBJECTIVE: To evaluate the effects of self-management education tailored to health literacy on medication adherence and blood pressure control. METHOD: This randomized controlled trial was conducted in 2018 with 118 elderly people with uncontrolled primary hypertension and inadequate health literacy. Self-management education was developed on the basis of the health literacy index. Medication adherence and blood pressure were assessed using 8-items Morisky Medication Adherence Scale and a mercury sphygmomanometer, respectively. RESULTS: At baseline, there were no significant between-group differences regarding participants' demographic characteristics, medical history, and medication adherence. After the intervention, between-group comparisons adjusted for pretest scores showed a significant reduction in the mean score of systolic and diastolic blood pressure and increase adherence to medication due to intervention (P < 0.05). However, the proportions of controlled systolic and diastolic blood pressure were not statistically significant different between-group (P > 0.05). CONCLUSION:Self-management education tailored to health literacy significantly promotes medication adherence but has no significant effects on control of blood pressure. PRACTICE IMPLICATION: To promote adherence to antihypertensive medications, tailored patient education to Health literacy is recommended. Limited pieces of evidence are available on the effectiveness of health literacy index-based interventions, so further studies are required.
