Characterizing re-triage guidelines: A scoping review of states' rules and regulations.

Background: State guidelines for re-triage, or emergency inter-facility transfer, have never been characterized across the United States.

Methods: All 50 states' Department of Health and/or Trauma System websites were reviewed for publicly available re-triage guidelines within their rules and regulations. Communication was made via phone or email to state agencies or trauma advisory committees to obtain or confirm the absence of guidelines where public data was unavailable.
