Intervention: Use of Pediatric Early Warning Score (PEWS) calculated from vital signs to predict adverse events in the emergency department
Who it was tested with: Children aged 28 days to 14 years triaged as 'emergency' (highest acuity) presenting to a tertiary teaching hospital emergency department in Tanzania.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"This was a prospective cohort study of children aged 28 days to 14 years who presented to the ED of a tertiary teaching hospital in Tanzania from 1st May to 30th June 2024 and who were triaged as 'emergency' (highest acuity). Physicians' estimates of the probability (0-100%) of an adverse event...were recorded for each patient on arrival. PEWS was calculated by the researchers from the child's vital signs, and not disclosed to the physician." This design allowed direct comparison of the two methods' predictive ability in a real-world emergency setting.
Study conducted at single tertiary referral hospital only; findings may not generalize to other emergency care settings with different resources and training; study design did not investigate reasons for superior performance of physician gestalt
