Adherence to drug therapy among hypertensive patients attending two district hospitals in Ghana
Abstract
Background: A major drawback to the management of hypertension among patients is poor adherence to pharmacother- apy. Factors that influence non-adherence to antihypertensive drugs could vary, depending on the prevailing condition of patient and setting. Knowledge of adherence patterns and behavior of hypertensive patients to pharmacotherapy could improve health-directed policies towards hypertension management.
Objective: The objective of this study was to determine factors that influence adherence to oral antihypertensive drugs among patients attending two district hospitals in the Volta Region of Ghana.
Methods: The study was cross-sectional. Respondents were hypertensive patients attending Krachi West District (n=187) and Hohoe Municipal (n=183) hospitals between March 2016 to May 2016. Data was collected using a structured question- naire and Morisky 8 Item Measurement of adherence scale.
Results: Adherence to oral antihypertensive drugs was 89.2%. However, more than half of these respondents appeared to have uncontrolled blood pressure; and this may be due to self-response bias, blood pressure being measured only on the day of the interview or use of fake drugs (which was not assessed in this study). The strongest predictors of adherence were; knowledge on hypertension, perception of severity of condition and the amount of alcohol consumed in a day by respondents.
Conclusion: Good adherence to oral antihypertensive drugs was observed in this population despite uncontrolled hyper- tension in a number of the respondents. The three independent predictors of adherence to antihypertensive medications in this study were respondent’s knowledge about hypertension, perception of severity of their condition and the amount of alcohol consumed in a day. Regular patient education and counseling by medical practitioners should be encouraged in these settings to improve patient adherence.
Keywords: Adherence; antihypertensive drug; hypertension; Ghana.
