Summary
Improving physician decision-making in trauma triage through targeted interventions can enhance care quality. Enhancing perceptual sensitivity is more cost-effective than altering decisional thresholds for trauma center transfers.
Area of Science:
- Health Economics
- Trauma Care
- Medical Decision Making
Background:
- Physician decision-making in trauma triage significantly impacts patient outcomes.
- Current trauma triage practices may be suboptimal, necessitating interventions to improve accuracy.
Purpose of the Study:
- To identify the most cost-effective intervention to improve physician decision-making in trauma triage.
- To compare hypothetical interventions targeting decisional thresholds versus perceptual sensitivity.
Main Methods:
- A Markov decision model was constructed from a societal perspective.
- Cost-effectiveness analysis compared current practice with interventions to alter decisional thresholds or perceptual sensitivity.
- Sensitivity analyses and Monte Carlo simulations were performed.
Main Results:
- An intervention to improve perceptual sensitivity had an ICER of $62,799/QALY gained.
- An intervention to alter decisional thresholds was less cost-effective ($104,975/QALY gained).
- Perceptual sensitivity interventions were favored at a $100,000/QALY willingness-to-pay threshold.
Conclusions:
- Targeted interventions in trauma triage decision-making can significantly improve quality of care.
- Improving physicians' perceptual sensitivity is a more cost-effective strategy than altering decisional thresholds.
- The optimal intervention strategy is context-dependent on specific trauma systems.
