Abstract
Hypertensive patients' inability or unwillingness to adhere to prescribed medications can significantly hinder their ability to achieve clinically acceptable levels of blood pressure control, which may lead to increased rates of cardiovascular disease. This research study examines the effectiveness of a clinical pharmacist intervention in improving medication adherence in patients with hypertension. A quasi-experimental design was utilized, and data was collected from patients at outpatient clinics. Patients were randomly assigned to either an intervention group (those who received structured clinical pharmacist services) or a control group (those who received routine care). The clinical pharmacist intervention included counseling, individualized patient education concerning their medications, adherence assessment, advice regarding lifestyle changes, and regular follow-up visits with a clinical pharmacist. Adherence was assessed pre- and post-intervention using a validated adherence measurement tool, and blood pressure was recorded to determine clinical outcomes. Findings from the intervention demonstrated a statistically significant difference in adherence levels between the clinical pharmacist intervention group and the control group; furthermore, the systolic and diastolic blood pressure levels were significantly lower in the intervention group than in the control group. These results support the important contributions of clinical pharmacists to improving patients' understanding of their medications, enabling them to take their medications regularly, and providing ongoing support to help them manage their disease over the long term.
