SP - ePub EP - ePub VL - ePub IS - ePub N2 - BACKGROUND: Patients' trauma burdens are a combination of anatomic damage, physiologic derangement, and the resultant depletion of reserve. Typically, Injury Severity Score (ISS) >15 defines major anatomic injury and Revised Trauma Score (RTS) <7.84 defines major physiologic derangement, but there is no standard definition for reserve. The Need For Trauma Intervention (NFTI) identifies severely depleted reserves (NFTI+) with emergent interventions and/or early mortality. We hypothesized NFTI would have stronger associations with outcomes and better model fit than ISS and RTS.

METHODS: Thirty-eight adult and pediatric U.S. trauma centers submitted data for 88,488 encounters. Mixed models tested ISS >15, RTS <7.84, and NFTI's associations with complications, survivors' discharge to continuing care, and survivors' length of stay (LOS).

RESULTS: NFTI had stronger associations with complications and LOS than ISS and RTS (odds ratios (99.5% CI): NFTI = 9.44 (8.46, 10.53), ISS = 5.94 (5.36, 6.60), RTS = 4.79 (4.29, 5.34); LOS incidence rate ratios (99.5% CI): NFTI = 3.15 (3.08, 3.22), ISS = 2.87 (2.80, 2.94), RTS = 2.37 (2.30, 2.45)). NFTI was more strongly associated with continuing care discharge but not significantly more than ISS (relative risk (99.5% CI): NFTI = 2.59 (2.52, 2.66), ISS = 2.51 (2.44, 2.59), RTS = 2.37 (2.28, 2.46)). Cross-validation revealed that in all cases NFTI's model provided a much better fit than ISS>15 or RTS<7.84.

CONCLUSIONS: In this multicenter study, NFTI had better model fit and stronger associations with the outcomes than ISS and RTS. By determining depletion of reserve via resource consumption, NFTI+ may be a better definition of major trauma than the standard definitions of ISS >15 and RTS <7.84. Using NFTI may improve retrospective triage monitoring and statistical risk adjustments. LEVEL OF EVIDENCE: III, Therapeutic.
