Efficacy of Pediatric Early Warning Score in evaluation of respiratory disease in-hospital patients / 中华实用儿科临床杂志

ABSTRACT

Objective To validate the efficacy of Pediatric Early Warning Score (PEWS) in severity evaluation of respiratory inpatients.Methods Four hundred and thirteen children with respiratory disease were hospitalized in Pneumology Department of Guangzhou Women and Children's Medical Centre from October 2012 to October 2013,of which 36 cases required Intensive Care Unit (ICU) treatment while the rest 377 controls did not.According to the disease severity,cases and controls were further categorized into 3 groupsno-monitor-required group (n =302,controls),monitor-required group (n =75,controls),ICU group (n =36).PEWS was assessed at admission in controls and 12 hours before ICU transfer,respectively.PEWS were compared among all groups and receiver operator characteristic curve(ROC) was performed.Results The median [interquartile rang(IQR)] age in ICU group was 10 months(4-13 months),monitor-required group was 10 months (6-16 months),and no-monitor-required group was 14months(6-24 months),and the difference was significant (H =13.59,P ＜ 0.01).The median (IQR) of PEWS in ICU group was 6 scores (6-7 scores),monitor-required groups was 5 scores (4-5 scores),on-monitor-required group was 2 scores (1-2 scores),and the difference was significant (x2 =255.641,P ＜ 0.01).PEWS in monitor required group and ICU group was 3.5 score with area under ROC (AUC) as 0.898 (95％ CI0.867-0.929,sensitivity0.907,specificity 0.893) and 4.5 with AUC as 0.978 (95％ CI0.964-0.992,sensitivity 1.000,specificity 0.862),respectively.Conclusions PEWS can be indicative for severity classification in hospitalized respiratory pediatric patients,and can serve as a potentially excellent screening tool for prediction of ICU admission.
