Medication adherence and its associated factors among diabetic patients at Zewditu Memorial Hospital, Addis Ababa, Ethiopia

Diabetes is a global problem with devastating human, social and economic impact. Anti-diabetic medications play a major role in the glycemic control of patients with diabetes. However, inadequate adherence compromises safety and treatment effectiveness, leading to increased mortality and morbidity. The aim of this study was to assess adherence to anti-diabetic medications and associated factors among patient with diabetes mellitus receiving care at Zewditu Memorial Hospital. Among the total of 146 diabetic patients (mean age 46.5 ± 14.7), the level of adherence to anti diabetic medication was 54.8% (80) whilst 45.2% (66) of the participants were non adherent. Multiple logistic regression showed that knowledge of medication (AOR = 4.905, 95% CI 1.64–14.62, medication availability (AOR = 0.175, 95% CI 0.031–0.987) and education level (AOR = 13.65, 95% CI 1.45–128.456) were reasons for non-adherence.
