The application of pediatric early warning score (PEWS) in emergency observation room



      To explore the value of pediatric early warning scoring system (PEWS) in an emergency observation room in China.


      The children who had been admitted consecutively to the emergency observation room from Jan, 2019 to Aug, 2020 were selected. Three most important time-points including the first value (admission value), the highest value during the observation (highest value), and final value (discharge value) of Brighton Pediatric Early Warning Score (PEWS) was evaluated in all patients.


      4717 patients were included. They were categorized into 3 groups, namely, discharged group (G1, n = 2320), specialized ward group (G2, n = 2128), and ICU group (G3, n = 269). The different PEWS values of admission value, highest value, and discharge value were significantly different among the 3 groups (P<0.001). Highest value of G1 and G2 were significantly lower than that of G3 (P<0.001). AUROC curves of different PEWS values were used to predict the possibility of PICU admission and PICU mortality within 24 h of admission, and the values were 0.698, 0.878, 0.974 and 0.709, 0.883, 0.951, respectively. The cutoff values for PICU admission of 3 different PEWS values were 2.5 (sensitivity 0.635, specificity 0.699), 3.5 (sensitivity 0.817, specificity 0.9), 3.5 (sensitivity 0.837, specificity 0.985). The cutoff values for PICU mortality of 3 different PEWS values were 4 (sensitivity 0.625, specificity 0.799), 4.5 (sensitivity 0.722, specificity 0.79), 4.5 (sensitivity 0.883, specificity 0.987). The discharge value had the strongest prediction ability.


      PEWS can be used for early identification and warning of critically ill children.
