| Summary: | Background: The prevalence of diabetes mellitus (DM) is steadily increasing worldwide, with
a significant DM population in Asian countries. Adherence to medications is important to
achieve good glycaemic control among patients with DM. Thus, patients’ adherence to their
medication regimen should be determined to optimise DM management.
Aims: To determine medication adherence and the relationship between patient profile and
medication adherence among patients with type 2 DM (T2DM).
Design: Cross-sectional survey.
Methods: This study was conducted in a public hospital in Selangor, Malaysia, from December
2016 to June 2017. Data was obtained through administration of the Medication Compliance
Questionnaire and an electronic medical records database. Multivariate logistic regression
analysis was used to determine the predictors of medication adherence.
Results: A total of 232 (95.9% response rate) patients participated in this study. The overall
percentage of medication adherence among patients with DM was 55.2%. The majority of
participants were female (53.4%), Malay (47.0%), aged 41–64 years (55.2%; mean age,
56.69 years), married (84.5%), unemployed (60.8%) and attended secondary school
(53.9%). The factors independently associated with adherence were ethnicity (odds ratio
[OR], 1.43; 95% confidence interval [CI]: 1.03–1.99) and haemoglobin A1c (HbA1c) level
(OR, 2.71; 95% CI: 1.56–4.72).
Conclusions: The medication adherence among patients with DM in a public hospital in
Selangor, Malaysia was low. A health intervention emphasising patient-centred care is
warranted to improve DM patients’ adherence to prescribed medication. Considering that
Malaysia has a multi-ethnic population, the patients’ ethnicity and their HbA1c levels need
to be considered in the implementation of any intervention to improve medication adherence.
Impact statement: Medication adherence is influenced by individual patients’
characteristics. To improve adherence to the medication regimen, nurses should consider
patients’ profiles |
