The new Sacco triage method (STM) mathematically optimizes resource allocation for mass casualty incidents, outperforming the Simple Triage and Rapid Treatment (START) method in simulations by maximizing expected survivors. This evidence-based approach enhances trauma care outcomes.

Area of Science:

  • Emergency Medicine
  • Mathematical Modeling
  • Trauma Surgery

Background:

  • Resource-constrained triage is critical in mass casualty incidents.
  • Current methods like START may not fully optimize resource allocation.
  • Developing evidence-based, outcome-driven triage systems is essential.

Purpose of the Study:

  • To formulate a precise mathematical model for resource-constrained triage, the Sacco Triage Method (STM).
  • To apply STM to blunt trauma using the Respiratory Rate, Pulse Rate, and Motor Response (RPM) score.
  • To compare the efficacy of STM against the Simple Triage and Rapid Treatment (START) method.

Main Methods:

  • Modeled triage as a resource allocation problem to maximize expected survivors.
  • Incorporated time-dependent survival probabilities and victim deterioration rates.

  • Utilized logistic functions based on 76,459 blunt trauma patients for RPM survivability predictions.
  • Employed linear programming to solve the STM model and compared outcomes with START simulations.

    • Main Results:

    • The RPM score demonstrated superior accuracy in predicting blunt trauma survivability compared to ISS and RTS.
    • STM consistently yielded higher expected survivorship than START across all simulated scenarios.
    • Mathematical simulations confirmed STM's effectiveness in resource-constrained environments.

    Conclusions:

    • STM provides a precise, evidence-based, and outcome-driven approach to resource-constrained triage.
    • The method maximizes expected survivors by considering resource limitations.
    • STM shows significant lifesaving potential and operational advantages, warranting further investigation.
