Performance Assessment of the Finnish Diabetes Risk Score (findrisc) as a Diabetes Mellitus type 2 Screening Test

Abstract

Objective: to evaluate the performance of the Finnish Diabetes Risk Score (findrisc) as a diabetes mellitus type 2 (dm2) screening test. Methods: validation study of diagnostic test. 295 participants without diagnosis of dm2, who were attending a Family Medicine Unit in Acapulco, Guerrero, Mexico, were selected using a simple random sampling. The findrisc was applied to rate the development of dm2 risk level. A fasting glucose test was taken as an important standard to diagnose dm2. The Mantel and Haenszel χ2 test and or calculation were performed to measure the association and the magnitude, as well as sensitivity, specificity and predictive values to evaluate the performance of the questionnaire. Results: it was determined that 156 patients (52.84%) had high risk to develop dm2, 35 of them were diagnosed with dm2 and 49 with pre-diabetes. Patients with low-risk, 26 had pre-diabetes and 5 dm2. A ≥15 score by findrisc was associated with altered fasting glucose ≥100mg/dl (or: 4.06, p=0.0001), pre-diabetes (or: 2.82, p=0.0002) and dm2 (or: 7.75, p=0.0001). The sensitivity and specificity of the questionnaire for the dm2 diagnosis was 87.50% and 52.55% respectively, with 95% ic statistically significant. Conclusion: the findrisc is a tool that potentially can be used for the dm2 screening in the Mexican population, it is practical, simple, fast, non-invasive, and economic and it can be used in daily practice of the family physician.
