Abstract

Background: Hypertension is one of the most prevalent non-communicable diseases in Indonesia. A lack of knowledge and medication adherence among hypertensive patients often hinders treatment success. The Medication Therapy Management (MTM) intervention approach has the potential to enhance the effectiveness of hypertension management at the primary healthcare level Objective: This analyzed the effect of MTM in im proving knowledge, adherence, and lowering blood pressure in hypertensive patients. Methods: A one-group pretest-posttest quasi experimental study was conducted at the Sidodadi Primary Healthcare Center from October to December 2024, involving elderly hypertensive patients (n=168) enrolled in the Elderly Program. The respondents were selected using stratified random sampling. The intervention was implemented over eight weeks and included patient assessment, education, counseling, monitoring, and documentation using MTM standards. Data were collected using Hypertension Knowledge Level Scale (HK-LS), the Morisky Green Levine Scale (MGLS), and blood pressure measurements. Statistical analysis was performed using the Wilcoxon signed-rank test Results: The majority (66.67%) of participants were female, the mean knowledge score significantly increased from 13.53 ± 3.66 without MTM to 20.65 ± 1.71 with MTM (p < 0.001), MGLS adherence score decreased from 2.29 ± 1.02 to 0.79 ± 1.14 (p < 0.001) reflecting improved adherence, and the mean blood pressure decreased from 154.52 ± 10.69 to 148.14 ± 11.38 (p < 0.001). Conclusion: MTM intervention was effective in improving knowledge, adherence, and lowering blood pressure in hypertensive patients, and can be implemented as a clinical pharmacy service model in primary healthcare facilities.
