Predictive capacity of trauma indices for hospitalization and intensive care unit admission.

The study was done in one private, well-resourced trauma center serving patients with supplementary health coverage or ability to pay, so the findings may not apply to public hospitals or other settings. Only 151 patients were included, and only 14 were admitted to the ICU, so the ICU findings rest on a small number of events. 71 eligible patients did not respond or refused consent, which may have changed the mix of patients studied. The study used retrospective emergency department records, and physiological measurements were not standardized in time, which can affect REMS and mREMS. The sample was mostly low acuity, with many patients discharged from the emergency room, so it says little about severely injured trauma patients. ISS and NISS require complete injury diagnosis, often after interventions, limiting immediate use in initial care.

Do not conclude that ISS and NISS can guide immediate emergency triage. The paper states these anatomical indices require a complete diagnosis of injuries, which often occurs after interventions, so they were not shown to work in initial care.
