Background and Objectives: Self-monitoring of blood glucose (SMBG) is an important strategy for patients to significantly reduce complications from type 2 diabetes mellitus (T2D). In Thailand, data on the prevalence of SMBG among elderly patients with T2D is currently lacking. The objective of this study was to evaluate the prevalence and factors associated with SMBG in elderly patients with T2D who visited the outpatient departments (OPDs) of Srinagarind Hospital.
Methods: This was a cross-sectional descriptive study in which data were collected between April and June 2023 from 230 diabetic patients, who visited Srinagarind Hospital OPDs, through a questionnaire survey. Descriptive statistics were used to summarize quantitative data as frequencies and percentages. For inferential analysis, the chi-square test, odds ratio (95% CI), and binary logistic regression were used, establishing statistical significance at p-values less than 0.05.
Results: 230 subjects were recruited with a 100% response rate. The results showed that 59.1% (95%CI: 0.53, 0.66) of the sample group used SMBG. Among the patients who performed SMBG, the most common frequency of testing was 1-4 times per week (72.8%), and most of the subjects performed SMBG by themselves (72.8%).
The important factors that significantly influenced the use of SMBG were the duration of having T2D for more than 20 years (OR 4.068, 95% CI: 1.984-8.340) and the use of insulin therapy as a treatment (OR 4.973, 95% CI: 2.490-9.931).
Conclusion: 3 out of 5 elderly patients with T2D at the OPD of Srinagarind Hospital used SMBG. The duration of having T2D for more than 20 years and the use of insulin therapy were the most important factors associated with the use of SMBG. The primary barriers to using SMBG were a lack of awareness of the method and insufficient knowledge of how to perform it.
