Barriers to Anti-Hypertensive Medication Adherence Among Patients in Private Healthcare in Edenvale, South Africa

Background: Hypertension is a major global public health problem whose prevalence is increasing across the world. In consideration of this, there is insufficient understanding of the barriers that hinder the taking of anti-hypertensive medication among patients. In this regard, the aim of this study was to analyze the possible barriers undermining adherence to anti-hypertensive medication among patients in private healthcare in Edenvale, South Africa. Methodology: This study used an exploratory cross-sectional research design within which quantitative data were collected through an online survey on a sample of randomly selected hypertensive patients attending private healthcare facilities in Edenvale. Participation in this study was voluntary, and informed consent was sought from each participant. Anonymity was assured during data collection through the de-identification of respondents and any data about them. The collected data were subjected to descriptive statistical analysis. Results: One hundred and twenty-two patients participated in this study. From this, 34.4% of participants revealed that lack of awareness was a barrier to a very small extent. Forgetfulness was a possible barrier to adherence to a large extent amongst 16.4% of participants, and 26.2% of the respondents had, to a large extent, doubts about their hypertension diagnosis. However, 42.6% revealed that side effects and difficulty taking medication whilst away from home (47.5%) were a barrier to a small extent. The fear of side effects (19.7%), interference of alcohol or drug use (29.5%) were challenges to a moderate extent. Conclusions: The findings of this study support that hypertensive patients in private healthcare encounter financial constraints, occasionally forget to take their medication, doubt their hypertension diagnosis, and lack awareness about the benefits of taking anti-hypertensive medication. This may be compounded by patients finding the anti-hypertensive medication regimen too complicated, feeling overburdened by having to take too many pills every day, the complexity of the medication regimens, perceived incorrect diagnosis, and lack of social support from family and friends. Understanding the extent of the barriers encountered by patients in taking anti-hypertension medication may help address adherence challenges, which may help improve health outcomes and lessen the burden on health systems in pursuing Sustainable Development Goal 3 and universal health coverage.
