Reasons for non-compliance among patients with hypertension at Vanga Hospital, Bandundu Province, Democratic Republic of Congo: A qualitative study

BACKGROUND: Hypertension is a serious public health challenge in both economically developing and developed countries. Patients on outpatient medication for hypertension at Vanga Hospital in the Democratic Republic of Congo (DRC) often present with uncontrolled hypertension and some with hypertension emergencies. On enquiry, the problem appeared to revolve around compliance. METHOD: The study was a qualitative, descriptive study using the focus group interview technique for data collection. Subjects were purposely selected. Interviews were conducted from 23 March to 19 July 2006. Three focus groups were formed: The first was heterogeneous in terms of gender (five males and three females), the second homogeneous (six males) and the last also homogeneous (six females). The group members varied with respect to characteristics such as place of residence, occupation and educational standard. The data collected were analysed using the thematic analysis method within grounded theory. RESULTS: Five themes emerged as possible explanations for non-compliance: Side effects discouraged patients from taking medication; patients took medication only when they experienced perceived symptoms of hypertension; poor knowledge of the disease and the medication used; lack of support by family members; and difficulty in obtaining antihypertensive medication. CONCLUSION: Side effects of the medication, lack of information and support, difficulty in obtaining the medication and the fact that the disease is mainly silent played a major role in the poor adherence to hypertension medication. Sustained health promotion and education should be undertaken at all levels of patient contact to ensure good compliance.
