Abstract

Background: The Paediatric Observation Priority Score (POPS) is
a specific Emergency Department (ED) physiological and observational aggregate scoring system, with scores of 0–18. A higher score indicates greater likelihood of admission. The Manchester Children’s Early Warning System (ManChEWS) assesses six physiological observations to create a trigger score, classified as Green, Amber or Red.
Methods: Prospectively collected data were used to calculate
POPS and ManChEWS on 2068 patients aged under 16 (mean
5.6 years, SD 4.6) presenting over one month to a UK District
General Hospital Paediatric ED. Logistic regression and ROC
comparison, using STATA 11, were used to investigate the ability
of ManChEWS and POPS to predict admission to hospital
within 72 h of presentation to the ED.
Results: Comparison of the area under the Receiver Operating
Characteristics (ROC) curve indicates that the ManChEWS ROC
is 0.67 (95% CI 0.65 to 0.70), SE 0.02, and the POPS ROC is
0.72 (95% CI 0.69 to 0.75), SE 0.02. The difference is statistically
significant (p < 0.01). At a POPS cut-off of ≥2, 80% of
patients had their admission risk correctly classified (Positive Predictive Value (PPV) of POPS 2, 38.94%) whereas for ManChEWS with a cut off of ≥Amber only 71% of patients were
correctly classified (PPV of ManChEWS Amber, 29.06%).
Conclusions: POPS is a more accurate predictor of admission
risk from the ED than ManChEWS and is more suitable to use
in an ED setting. Replacing ManChEWS with POPS would
appear to be clinically appropriate in a Paediatric ED and multicentre validation of this proposal would be helpful.
