Drug compliance among hypertensive patients in Kassala, Eastern Sudan

Abstract

A cross-sectional study of hypertensive patients was conducted and drug compliance was estimated. Factors associated with compliance, status of blood pressure control and occurrence of complications were assessed. Compliance was 59.6% as measured with the pill count method. We found 92% of compliant patients had controlled blood pressure in comparison with 18% of non-compliant patients, and 30.1 % of the compliant patients had complications in comparison with 46.3% of the non-compliant patients. While the compliance rate was reasonable, 36.8% of patients were non-compliant because they could not afford to buy antihypertensive drugs. Inability to buy drugs was negatively and significantly associated with compliance. These patients experienced uncontrolled blood pressure and other complications.
