RESUMEN
Prevalence of chronic kidney disease (CKD) is increasing and CKD has a long asymptomatic phase suitable for screening. SCORED (Screening for Occult Renal Disease) is a prescreening test which has compared favorably with KEEP. We report the results of SCORED testing in subjects attending a World Kidney Day event. After SCORED, subjects were tested for creatinine, urinary albumin and creatinine, and renal ultrasound. Eighty-eight subjects participated (32 men; mean age 59.7 ± 14.8 years; 58% hypertensive and 15.9% diabetics) of which 60 had a high score for kidney disease. Thirty-eight of 47 (80.8%) subjects that were further evaluated had a high-risk score. All subjects with CKD had a high score (100% sensitivity). SCORED showed low specificity (24.3%), but a high negative predictive value (100%). Including albuminuria in the definition of CKD increased the positive predictive value to 43.6%. In conclusion, SCORED is good for prescreening subjects for CKD in a European population as it captures all patients with CKD. Moreover, in subjects with low risk, the probability of CKD is low. SCORED is useful in alerting the general population and the medical community about the risk factors of CKD.
