This randomized controlled study aimed to assess the results of a program intended to promote the medication adherence of patients with hypertension, through providing a telepharmacy service. 65 patients with hypertension from Nakhon Pathom Hospital were included in the study. The patients were randomly assigned to one of two groups - an intervention group or a control group. 35 patients were assigned to the intervention group and 30 patients were assigned to the control group. Patients in the intervention group received messages to remind them to take their medicine. They also received information relating to the risks and severity of hypertension, advice on positive behavioural changes, diet and exercise, in text, infographic, or video form every day for 3 months. In addition, the patients were able to respond and communicate with a pharmacist anytime through the LINE application. In the control group, the patients received the standard care and information normally provided. Outcomes were evaluated through the Morisky Medication Adherence Scale 8-item (MMAS-8) and Health Belief Model evaluation form. Data were analysed by descriptive and inferential statistics including percentage, mean, standard deviation, Man-Whitney U Test, Wilcoxon Signed Ranks Test and Binary Logistic Regression. The results revealed that the medication adherence promoting program was related to moderate to good medication adherence, with statistical significance (p-value < 0.001). The mean adherence score for the intervention group (mean±SD=6.02±0.75) was higher than that for the control group (mean±SD=4.47±0.85) with statistical significance (p-value < 0.001). With respect to the Health Belief Model, the results showed that the intervention group returned higher scores in perceived susceptibility, perceived severity and perceived benefit, and a lower score in perceived barriers than the control group, at a level that was statistically significant (p-value<0.001). Therefore, the medication adherence promoting program using telehealth can assist patients to adhere to their medication program. This program can encourage patients to take their medication, and help disease control on an ongoing basis.
