Analysis of Effectiveness and Efficiency of Diabetes Screening Tool: A Case Study of Nam Phong District, Khon Kaen Province, under the Integrated National Diabetes Risk Screening Project, Department of Medical Services, 2023-2024

Abstract

This research aimed to analyze the effectiveness and efficiency of the Department of Medical Services' diabetes screening tool and to study factors associated with diabetes risk screening results. This cross-sectional analytical study analyzed secondary data from the National Diabetes Risk Screening Project. The sample consisted of 800 participants from 18 Sub-district Health Promoting Hospitals in Nam Phong District, Khon Kaen Province, during July-September 2023. Data were analyzed using descriptive statistics, chi-square tests, and odds ratios with 95% confidence intervals.
The results showed that the department of medical services' screening tool had 100% sensitivity, 41.83% specificity, 2.34% positive predictive value, and 100% negative predictive value. A high-risk group of 470 participants (58.75%) was identified, with 11 new diabetes cases detected (1.38%). The tool reduced blood glucose testing by 41.25%. Factors with the highest association were over-standard waist circumference (χ²=167.89, OR=7.2, 95%CI:5.1-10.1), age ≥50 years (χ²=156.78, OR=3.5, 95%CI:2.6-4.7), and BMI >27.5 (χ²=145.23, OR=16.2, 95%CI:8.3-31.6), (p<0.001). The screening tool effectively identifies high-risk groups and significantly reduces costs, with waist circumference being the most important predictive factor.
