- Abstract
Poor adherence to antidiabetic medication, which causes diabetesrelated complications and increases medical burden, has been an important concern for both patients and physicians. Enhancing patients' beliefs about medicine can partially improve their non-adherence status to medications. The research evaluated the factors associated with beliefs about antidiabetic medicine in outpatients with type 2 diabetes at Hue University Hospital. A cross-sectional study was conducted on 396 outpatients diagnosed with type 2 diabetes mellitus at the Endocrinology Clinic at Hue University Hospital following the eligibility and exclusion criteria using convenient sampling method. We interviewed the patients using a questionnaire based on the Vietnamese version of the Beliefs about Medicines Questionnaire (BMQ-V) published by Dr. Nguyen Thang et al. Chi-squared, Fisher tests, paired sample t-tests, one-way ANOVA, Mann-Whitney test and Kruskal-Wallis were first used to determine variables associated with scores of BMQ-V and its subscale. Then Multivariate Regression Analysis was applied on those variables against scores of BMQ-V and its subscale. All data was analyzed using SPSS software version 20.0. The study was conducted on 396 patients with type 2 diabetes, with a median age of 66.9±13.7 years. According to the BMQ-V questionnaire, the participants' beliefs about medicine had a mean score of 50.3±8.1. Multivariate regression analysis revealed a statistically significant association between BMQ score and HbA1c control status, duration of diabetes, and home blood glucose monitoring (p=0.001; p=0.003; p<0.001). The diabetic patients with a longer disease duration (S-N: 9.1±3.5) had more trust in the effects of the medications on their health than that of patients with a shorter duration (S-N: 11.3±4.4), the patients with uncontrolled HbA1c levels (S-N:9.6±3.7) felt that taking antidiabetic medicines was more necessary than controlled group (S-N:10.9±4.4) with statistical significance. The group that regularly (>2 times/week) monitored blood sugar at home seemed to have a lot of concerns about harmful long-term effects as the mean scores on the Specific-Concerns, General-Overuse, and General-Harm subscales were significantly lower than those of other groups (p<0.001; p=0.003; p=0.001). Therefore, we need to improve patients' positive beliefs and gradually reduce their negative beliefs about medicines, raise the awareness of patients about monitoring their blood glucose at home, the long-term side effects of medicines, and change their lifestyle, thereby increasing medication adherence and improving treatment effectiveness.
