Objectives: To assess the accuracy of the Yale Observation Scale (YOS) as a screening test in detecting serious illness in febrile infants.
Materials and methods: An observational, prospective and longitudinal study which included febrile infants aged 3 to 24 months who presented to the Emergency Department of the Arzobispo Loayza Hospital from April 13th to June 6th 2012 were scored with the YOS before clinical examination. Inpatients were followed up until the diagnosis confirmation and discharge. Outpatients were followed up by calling them for a maximum of 5 days.
Results: Data from 61 infants were analyzed. 30 (49%) had well appearance, 21 (35%) ill appearance and 10 (16%) very ill appearance. Only 10 developed serious illness, 9 out of these 10 had a YOS score ≥16. The mean YOS score for serious illness is 17 (p= 0,007). For a cut off value of 10, sensitivity, specificity, PPV, NPV, LR+ and LR- of YOS was 100%, 59%, 32%, 100%, 2,43, and 0 respectively. For a cut off value of 16, sensitivity, specificity, PPV, NPV, LR+ and LR- of YOS was 90%, 98%, 90%, 98%, 45,9, and 0,1 respectively. Area under ROC curve was 0.982.
Conclusions: This study demonstrates the potential utility of the Yale Observation Scale as a screening test for predicting serious illness in febrile children aged 3-24 months because it is simple, reproducible, cost-effective and have a high sensitivity.
