Objective: Diabetes mellitus is a growing public health problem in many countries including Ghana. Adherence to drugs, especially among patients with type 2 diabetes mellitus (T2DM) is often poor is some resource-poor settings. The objective of this study was to assess adherence to oral hypoglycemic drugs and factors that affect adherence among patients with T2DM in the Volta Region of Ghana. Methods: The study was cross-sectional and conducted among 400 patients with T2DM attending diabetic clinics at 4 randomly selected hospitals in the Volta Region of Ghana between January 10 and March 30, 2015. Patients were interviewed using a structured questionnaire and other data collection tools to determine the commonest self-reported reason(s) for nonadherence. Adherence was assessed using the 8-item Morisky Medication Adherence Scale. Multivariate analysis was performed between adherence and statistically significant patient variables. Results: Adherence to oral hypoglycemic drugs among T2DM patients was 47.75%. The odds of adherence with fasting blood glucose between 1 and 6 mmol/L was approximately two-fold (adjusted odd ratio [aOR] =1.92, confidence interval [CI]: 1.11–3.32) versus the odds of having fasting blood glucose of above 10 mmol/L. The odds of adherence among patients with tertiary education was approximately three-fold (aOR = 3.01 CI: 1.44–6.269) versus patients with no formal education. The commonest self-reported reason for nonadherence was forgetfulness. Conclusion: Adherence to oral hypoglycemic drugs among T2DM patients in the current study was sub-optimal. Therefore, in such settings, management of T2DM must include strategies to identify nonadherent patients, and regular patient education and counseling.
