Abstract


ABSTRACT

 

Hypertension is a chronic medical condition which remains inadequately managed. Drug adherence is a critical parameter in achieving optimal blood pressure control in patients undergoing antihypertensive therapy. This study was aimed to determine the proportion of hypertensive patients who were adherent to antihypertensive treatment regime and to identify the predictors of drug adherence in patients with hypertension in USM Hospital. A cross-sectional study was conducted and simple random sampling was performed to select 114 subjects. Subjects were interviewed using a structured validated Medical Adherence Questionnaire (MAQ) on their demographic background and drug taking behaviour. SPSS version 22 was used for data entry and analysis. Multiple binary logistic regression was used to identify the factors associated with drug adherence among the patients. Out of the 114 subjects, 71 (62.3%) were adherent to their antihypertensive treatment regime (95%CI 0.53, 0.71). The statistically significant independent factors were marital status (married/divorced or widowed) [AOR 0.31, 95% CI 0.10, 0.99, p=0.057] use of traditional medicines [AOR 0.19, 95% CI 0.07, 0.57, p=0.03] and household income (middle) [AOR 9.72, 95% CI 2.89, 32.67, p<0.001]; (high) [AOR 6.23, 95% CI 1.18, 32.96, p=0.031]. Patients who were married, have middle or high income and did not take traditional medicines were more likely to adhere to their antihypertensive medication.
