The establishment of Trauma Transfer and Referral Centers was established by statute, OS §63-1-2530.8.  – Rule: OS 310:641-3-130 In Oklahoma this program is known as TReC.

This requirement is for communities with = or > than 300,000 in population.

TReC establishes that ambulance services transporting pre-hospital patients or transferring patients’ inter-facility must contact the Trauma Transfer and Referral Center if their destination hospital is within:

  1. Oklahoma County or communities that are contiguous to it including Mustang, Norman and Yukon.  These are Oklahoma Trauma Regions 6 and 8. 
  2. Tulsa County. This is Oklahoma Trauma Region 7.

Pre-hospital patients or transferring patients inter-facility must contact TReC before entering into these counties and communities.


  1. Ensure patients go directly to the most appropriate facility
  2. Reduce over-triage and under-triage
  3. Preserve highest-level resources for the most severely injured
