Updated field triage rules catch nearly all major trauma
Performance of updated American College of Surgeons field triage guidelines in identifying need for trauma center care
Canadian Journal of Emergency Medicine · 2026-10-08 · Added 9 October 2026
A Canadian health-records review of 1,427 patients transported to a level 1 trauma centre found the 2021 US field triage guidelines were highly sensitive (97.3%) but poorly specific (13.3%) for identifying need for trauma centre care.
- Study type
- Cohort
- Design
- Retrospective health records review
- Participants
- 1,427 patients at a level 1 trauma centre
- Main finding
- Field Triage Guideline criteria had 97.3% sensitivity and 13.3% specificity for trauma centre need (AUROC 0.80), with mental status and vital signs most strongly associated
- Caveat
- Single-centre cohort of transported patients only, retrospective design, US-derived criteria applied in Canada
- Bottom line
- Hypothesis-generating
Why it matters in Australia (High relevance). Prehospital trauma triage tools and undertriage targets are shared problems across Australian services, and the finding that mental status and vital signs drive accuracy applies to any field triage scheme.
Learning goal
Weigh the trade-off between sensitivity and overtriage when applying updated field triage criteria to major trauma patients.

Prehospital variables can't pick pelvic binder benefit
Blinded imaging review of 298 CT-confirmed pelvic ring injuries found binder application would be potentially mechanically unfavourable in 56% of cases, and no prehospital variable (hypotension, shock index, mechanism, GCS) discriminated favourable morphology well.

Prehospital TXA helps fibrinolytic shutdown

Field fluids before ROSC in crush arrests
A single-centre retrospective study of 37 earthquake victims in cardiac arrest after the 2023 Kahramanmaraş earthquakes found ROSC in 27% — exclusively in the 25 patients who received pre-hospital fluids (mean ~1.5 L) — with better pH, lactate, and potassium on arrival.
