Summary
A new national major trauma triage tool was developed using expert consensus to improve patient selection for major trauma centres. This standardized approach aims for greater accuracy and consistency in emergency care decisions.
Area of Science:
- Emergency Medicine
- Trauma Surgery
- Health Services Research
Background:
- Major trauma centre (MTC) care improves outcomes for severely injured patients.
- Current triage tools in England vary, potentially impacting accuracy and consistency.
- A standardized national triage tool is needed for better decision-making.
Purpose of the Study:
- To derive and develop a standardized major trauma triage tool for English trauma networks.
- To enhance triage accuracy, cost-effectiveness, and reproducibility in patient selection for MTCs.
Main Methods:
- An expert consensus process involving a web-based Delphi survey and roundtable meetings.
- Identification and confirmation of key triage predictors and thresholds.
- Public and patient involvement focus groups to ensure acceptability.
Main Results:
- Consensus reached on nine triage variables across two domains after three Delphi rounds.
- A three-step tool integrating physiology, anatomical injury, and clinical judgment was recommended.
- The proposed triage tool was positively received by public and patient focus groups.
Conclusions:
- A new expert-derived major trauma triage tool has been developed with defined parameters.
- Prospective evaluation is necessary to confirm its clinical and cost-effectiveness, usability, and acceptability.
