Aim: The present study measured the medication knowledge and medication adherence in patients with type 2 diabetes in Brunei Darussalam. Demographic details and diabetes knowledge were also evaluated. Methods: A cross-sectional study conducted via the administration of a structured questionnaire consisting of 4 sections via a face-to-face interview. Results: A total of 118 participants were interviewed. A majority of the participants were aged 40 years or above (106, 89.8%). The mean number of total medications that the participants were taking was 7.36 ± 2.87 and the mean number of antidiabetic medications was 2.39 ± 1.06. As for the antidiabetic therapy, the largest proportion of the participants were taking oral antidiabetic medications only (87, 73.73%). In the diabetes knowledge section of the questionnaire, more than half of the participants (63, 53.34%) scored higher than the acquired mean score. Family history, education level, and total medications taken were significantly correlated with diabetes knowledge. However, in the medication knowledge section of the questionnaire, the mean score (3.37 ± 1.38) was below the intended score for good knowledge. Medication knowledge has been significantly associated with gender, family history and total medications taken. A majority of the participants reported non-adherence (74, 62.71%) due to various reasons. In this study, those of the Malay race were significantly correlated with adherence to their medication regimen. This study also revealed that there is no significant relationship between diabetes knowledge, medication knowledge and medication adherence. Conclusions: The present study provides insights in regard to patients with type 2 diabetes in Brunei Darussalam and their knowledge towards the disease as well as their medications. Despite the lack of significance between the variables, the rate of non-adherence is still alarming. Further studies are required to better understand the barriers to non-adherence in these patients.

Introduction Diabetes is becoming an increasingly common condition across the world including Brunei Darussalam. Bruneian population, although is relatively small, represents a miniature urban community of neighbouring Southeast Asian countries as they share similar dietary and ethnicity patterns. Thus, it would be valuable to examine the findings of studies conducted among Bruneians. This study aimed to identify and review research related to the practice of patients with DM in Brunei Darussalam in order to identify associated factors influencing diabetic medication knowledge and adherence. Methods This narrative review analyzed literature related to DM and its therapy in Brunei Darussalam. Other issues consisting of knowledge and adherence related to DM were also explored. Databases (Scopus, PubMed, and Google Scholar) were used to search literature published up to May 2022. Search terms “diabetes mellitus”, “Brunei” combined using Boolean operator were used. Results and Discussion Conducting appropriate studies in Brunei Darussalam can benefit the government and policymakers to implement effective measures and programmes to combat the diabetes epidemic. Despite the government’s efforts, additional relevant stakeholders must be included in order to work together and engage in these initiatives in order to increase diabetes awareness, give people the power to make healthy decisions, and ultimately reduce the prevalence of diabetes in Brunei Darussalam. Patients’ medication knowledge proficiency plays a main component of ensuring appropriate and safe use of medication prescribed to them. Conclusion Relatively poor medication knowledge and inappropriate diabetes-related practices were observed in studies conducted in Brunei Darussalam. However, no study has been done which directly measures both medication awareness and compliance among Brunei Darussalam T2DM patients. Future studies can focus on the relation between these two factors in different geographical locations of the world that are characterized by different diabetes-related practices and culture.
