Area of Science:

  • Emergency Medicine
  • Health Services Research

Background:

  • Emergency Medical Services (EMS) personnel make critical triage and nontransport decisions in the field.
  • Standardized research criteria for medical necessity in EMS are currently lacking.

Purpose of the Study:

  • To review existing literature on triage and nontransport decision-making methodologies in EMS.
  • To identify themes that can inform the development of validated medical necessity criteria for EMS.

Main Methods:

  • Systematic literature review of studies on EMS triage and nontransport decisions.
  • Analysis of methodologies used for field decision-making and outcome assessment.

Main Results:

  • No universally accepted "standard" triage criteria for medical necessity in EMS have been established.

  • Emerging themes for triage criteria include vital signs, chief complaints, and physical exam findings.
  • Outcome measures for evaluating decisions include hospital admission, critical events, death, and diagnosis.

    • Conclusions:

    • Consensus on elements for medical necessity criteria in EMS is achievable.
    • Further validation and refinement of identified themes are necessary to establish robust criteria.
