BackgroundAdherence to medications improves glycaemic control and reduces diabetes-related morbidity and mortality. ObjectivesThe study assessed drug therapy for type 2 diabetes, glycaemic control and association of medication adherence with socio-demographic and clinical data, among adult diabetic patients attending a healthcare facility. MethodsCross-sectional survey and hospital records were used to obtain data. The study included 200 adults with type 2 diabetes mellitus in a Nigerian healthcare facility. Data on patients clinical characteristics, diabetes drug therapy and medication adherence were collected, entered and anlaysed using SPSS version 24 (P <0.05). Primary outcome measure was medication adherence among the patients, while secondary outcome measures was glycaemic control. ResultsA total of 200 (100%) respondents participated in the study and the majority 141(70.5%) were over 60 years old. Oral medications were mostly used 187(93.5%), particularly, metformin 199(99.5%) and pioglitazone 100(50.0%), while dipeptidyl peptidase-4 inhibitors were not used at all. Patients mostly had poor glycaemic control 159 (79.5%) and majority 152(76.0%) did not practice self-blood glucose monitoring. Moderate medication adherence was predominant in the population. Class of medicine and socio-demographics were not significantly associated with medication adherence (P>0.05), unlike results of blood glucose self-tests (p=0.001). ConclusionOral antidiabetics, particularly metformin and pioglitazone were mostly used. Poor glycaemic control and moderate adherence were found in the patients, and medication adherence was associated with self-glucose monitoring. This emphasises the need for regular diabetes education on medication adherence.
