Five scene findings flag kids needing blood
Prehospital Risk Stratification for Early Transfusion in Pediatric Trauma: A National Trauma Data Bank Analysis
Prehospital Emergency Care · 2026-10-16 · Added 19 October 2026
Retrospective national trauma registry analysis testing five EMS-observable findings for spotting injured children who need early blood — altered GCS (aOR 8.38), penetrating mechanism (aOR 5.87) and age-adjusted hypotension (aOR 5.39) led, and a three-tier decision tree put 36.8% of early transfusions into just 3.3% of kids.
- Study type
- Registry
- Design
- Retrospective registry cohort with decision-tree (CART) analysis
- Participants
- 79,764 EMS-transported children aged 1–15
- Main finding
- All five predictors independently predicted blood within 4 h of ED arrival; low/intermediate/high CART tiers had 1.2%/6.1%/36.7% transfusion rates, and the high-risk tier captured 36.8% of all early transfusions
- Caveat
- The outcome is in-hospital transfusion rather than prehospital shock, and children missing prehospital vitals were excluded.
- Bottom line
- Hypothesis-generating
Why it matters in Australia (Medium relevance). The five predictors are basic observations any crew already takes, but prehospital blood is limited to a handful of Australian services, so for most crews this is a destination-and-warning tool rather than a transfusion trigger.
Learning goal
Strengthen my ability to recognise scene findings in injured children that signal a need for early blood product transfusion.
