Exploring the Impact of Pillbox Usability on Adherence and Glycemic Regulation in Primary Care Setting With Type 2 Diabetes Mellitus Syofyan

Objectives: Type 2 diabetes mellitus (T2DM) needs continuing adherence and effective self-management strategies to achieve optimal glycemic control. This investigation sought to explore the link between pillbox usability and patient adherence, patient adherence, and random blood glucose (RBG) levels, in addition to pillbox usability and RBG levels in T2DM. Methods: This observational study involved 33 patients with T2DM receiving care from the Lubuk Kilangan Primary Health Center, selected through purposive sampling. Pillbox usability was assessed using the System Usability Scale questionnaire, medication adherence was measured over a monthly period using the pill count method, and RBG data were obtained from patients’ clinical records. Data were analyzed using Spearman’s rank correlation test to consider relationships between variables. Results: The findings indicated no significant correlation between pillbox usability and either medication adherence or RBG levels (p>0.05). However, a significant negative link existed between medication adherence and RBG levels, with moderate strength (r=−0.456; P=0.008). Conclusion: These findings point to improved medication adherence contributing to better glycemic control, as indicated by lower RBG levels. Nevertheless, pillbox usability was not found to have a significant impact on either adherence or blood glucose control.
