Learning Objective 1: The learners will be able to learn the process of how to develop and test a screening tool that aims to identify people with pre-diabetes.
Learning Objective 2: The learners, in particular the community nurses can utilize the prediabetes screening tool(PST) to assess people at high risk of developing the diabetes.
Methods: We conducted a consecutive community-based prediabetes survey. The subjects recruited from the community and department of physical examination of one medical center and one metropolitan hospital in southern Taiwan. The subjects (N=1112) completed the questionnaire and underwent a fasting glucose test after their regular physical examination. The area under the receiver operating characteristic curve (AUC) was used in this study to examine the sensitivity and specificity of PST .
Results: Risk factors comprised in the PST include age, smoking status, waist circumference, systolic blood pressure, hypertension, and history of cardiovascular disease. Scores for the screening tool ranged between 4 and 14 points. The area under the AUC was 0.72 (95%CI:0.69, 0.76) for the cutoff point of 4, the sensitivity , specificity, positive predictive value, and negative predictive value of the screening tool was 76.89%, 54.76%, 38.23%, and 86.68%, respectively.
Conclusion: Empirical data supports the PST is a valid and feasible screening tool that could be widely used to early identify prediabetes people who may be asymptomatic in the community.
