^a.Patients presenting to an emergency department at or directly admitted to a Level I or II trauma center, with no subsequent transfer, were defined as Appropriate Triage on the field.

^b.Patients presenting to an emergency department at or directly admitted to a Level III, IV, or non-trauma center, with no subsequent transfer, were defined as Under-Triage on the field.

^c.Patients emergently transferred from any emergency department to a Level I or II trauma center were defined as Optimal Re-Triage.

^d.Patients emergently transferred from any emergency department to a Level III, IV, or non-trauma center were defined as Sub-optimal Re-Triage.

^e.Values were obtained from a hierarchical logistic regression model with in-hospital mortality as the outcome. Age, sex, race, primary payer, Injury Severity Score, Elixhauser Comorbidity Index, hospital bed size, hospital medical school affiliation, trauma funding status, re-triage status, and a re-triage status by funding status interaction term are included as fixed effects. An intercept defined by hospital ID was used as the sole random effect.

^f.Trauma Funding Status was determined by the absence ($0.00) or presence (>$0.00) of per capita state trauma funding in the state that the patient was hospitalized in.
