Trauma Categorization Explained

Designation Vs. Verification

Trauma centers levels across the United States are identified in two fashions – A designation process and a verification process.  The different levels (ie. Level I, II, III, IV or V) refer to the kinds of resources available in a trauma center and the number of patients admitted yearly.  These are categories that define national standards for trauma care in hospitals.  Categorization is unique to both Adult and Pediatric facilities.

Trauma Center designation is a process outlined and developed at a state or local level.  The state or local municipality identifies unique criteria in which to categorize Trauma Centers.  These categories may vary from state to state and are typically outlined through legislative or regulatory authority.

Trauma Center Verification is an evaluation process done by the American College of Surgeons (ACS) to evaluate and improve trauma care.   The ACS does not designate trauma centers; instead, it verifies the presence of the resources listed in Resources for Optimal Care of the Injured Patient.  These include commitment, readiness, resources, policies, patient care, and performance improvement.

This is a voluntary process by the Trauma Center being verified and lasts for a 3-year period.

Trauma Center Levels

As mentioned above, Trauma categories vary from state to state.  Outlined below are common criteria for Trauma Centers verified by the ACS and also designated by states and municipalities.  Facilities are designated/verified as Adult and/or Pediatric Trauma Centers.  It is not uncommon for facilities to have different designations for each group (ie. a Trauma Center may be a Level I Adult facility and also a Level II Pediatric Facility).
