Factors Associated with Medication Adherence among Patients with Type 2 Diabetes Mellitus: A Hospital-Based Cross-Sectional Study in Nepal.

As diabetes increases globally, high mortality increases due to complications of uncontrolled sugar. Medication adherence is important to control blood sugar and prevent its complications. Objective of the study was to identify factors associated with medication adherence among type 2 diabetes patients. A cross-sectional study was conducted among 343 patients visiting Dhulikhel Hospital, Nepal, for their fasting blood sugar test from September to December 2016. Inclusion criteria: patients with type 2 diabetes, under diabetes medication for past three months (minimum), age ≥ 18 years. The outcome of the study was medication adherence measured using the eight-item Morisky medication adherence scale (MMAS-8) (© 2006 Donald E. Morisky). Multivariate logistic regression was used for the analysis. Results showed that 61% of respondents had high medication adherence; adherence was positively associated with formal education [AOR: 2.43 (95% CI: 1.34, 4.39)] and attendance at diabetes counseling [AOR: 1.76 (95% CI: 1.02, 3.04)] after adjusting for age, occupation, medicine intake duration and diabetes medicine types. The study concluded that formal education and attendance at diabetes counseling positively affected patients' adherence to medicine. We encourage healthcare institutions to provide counseling services to all the patients with type 2 diabetes and focus more on those who are less educated.
