Insights
Patient understanding, medication availability, family support, and clinic visits facilitate hypertension medication adherence. Barriers include drug shortages, self-prescribed pain relievers, and stigma.
Area of Science:
- Cardiology
- Public Health
- Sub-Saharan Africa Health
Background:
- Hypertension is a major cardiovascular disease and risk factor in sub-Saharan Africa.
- Uncontrolled hypertension leads to severe health issues like heart failure, stroke, and kidney failure.
- Medication non-adherence is a significant challenge impacting hypertension management and patient outcomes.
Purpose of the Study:
- To explore patient perspectives on factors influencing adherence to antihypertensive medications.
- To identify common reasons for both adherence and non-adherence to blood pressure medication.
Main Methods:
- A qualitative study was conducted with hypertension patients at a regional referral hospital in southwestern Uganda.
- Data were collected through one-on-one in-depth interviews.
- Thematic analysis was used to analyze interview transcripts.
Main Results:
- Key facilitators of adherence included understanding prescribed medication, medication availability, family support, and regular clinic reviews.
- Barriers identified were medication stock-outs, use of self-prescribed analgesics, and social stigma.
- Sixteen participants contributed data to the study's findings.
Conclusions:
- Improving medication availability and providing patient-centered care are crucial.
- Educating patients on the risks of self-prescription and reducing stigma can enhance medication adherence.
- Interventions should focus on addressing identified barriers to improve hypertension management.
Background:
Hypertension is a significant cardiovascular disease (CVD) and driver to CVD disorders in sub-Saharan Africa. It is a major independent risk factor for heart failure, stroke, and kidney failure. Persons living with hypertension attend to many aspects of self-care to manage their condition, including high blood pressure medication adherence to control of blood pressure. Rates of medication non-adherence, and thus uncontrolled hypertension, remain high and contribute to poor health outcomes. Understanding barriers and facilitators to adherence to hypertension therapies can help improve health outcomes.
Objective:
The aim of the study was to describe the common reasons for adherence and non-adherence to antihypertensive medication from patients' perspectives.
Methods:
A qualitative study engaged clients of an out-patient clinic of a regional referral hospital in southwestern Uganda who were living with hypertension as participants. One-on-one in-depth interviews provided the narrative data. The interview transcripts were analyzed using thematic analysis.
Findings:
Sixteen participants provided the data for the findings. The themes identified as facilitators for adherence to antihypertensive medication were patients' understanding of prescribed medication, availability of medication for hypertension, family support for patients living with hypertension, and regular review appointments at the hypertensive clinics. Conversely, lack of supply in government dispensaries, use of self-prescribed analgesic medication, and stigma were identified as barriers and challenges of adherence to antihypertensive medication.
Conclusions:
There is an urgent need for the health ministry to improve availability of high blood pressure medication and for health care providers to deliver individualized patient centered care, and sensitization on danger of self-prescription and measures that reduce stigma. These strategies may improve adherence to high blood pressure medication.
