Comparative Study
Field trauma triage: combining mechanism of injury with the prehospital index for an improved trauma triage tool.
The objective of this study was to combine a physiologic triage score (prehospital index, PHI) with criteria regarding mechanism of injury (MOI) to increase the efficacy of trauma triage. The specific question being asked was: will the combined score improve the sensitivity and specificity over that of the individual scores? ⋯ The combined PHI/MOI score was better at identifying those patients with ISS scores > or = 16 compared with the PHI and MOI scores alone. Although this permitted superior triage (and minimized overtriage), the combined score did not identify all major trauma patients.

Cerebral fat embolism syndrome is an uncommon complication of trauma. We present a patient who developed cerebral fat embolism syndrome secondary to long-bone fractures. Although computed tomography of the brain failed to show any intracranial lesion, magnetic resonance imaging (MRI) detected scattered, high-signal-intensity lesions on T2-weighted images. 99mTc-d, 1-hexamethyl-propylene amine oxine single photon emission computed tomography (99mTc-HMPAO SPECT) and transcranial Doppler sonography (TCD) demonstrated low cerebral blood flow in the acute stage. MRI, 99mTc-HMPAO SPECT, and TCD correlated well with the clinical course of cerebral fat embolism syndrome.

To determine how often the management of patients with blunt facial trauma was altered by plain roentgenograms or facial computed tomographic (CT) scans compared with findings from physical examination. ⋯ Physical examination reliably assessed the facial skeleton for clinically significant fractures in the majority of patients. In an alert and cooperative patient, CT scan is not required before operative repair in all cases. CT scans are expensive, time-consuming, and labor-intensive and in selected cases add little clinical information to that obtained by physical examination and plain films.

The Pediatric Risk Index (PRI) uses established measures of physiologic derangement (Pediatric Trauma Score and Glasgow Coma Scale) and anatomic severity (Injury Severity Score) to identify those patients at risk of death, impairment, or extensive resource utilization. ⋯ The PRI effectively identifies injured patients at risk for dying, impairment, or extensive intensive care unit care.

Trauma registries are an essential but expensive tool for monitoring trauma system performance. The time required to catalog patients' injuries is the source of much of this expense. Typically, 15 minutes of chart review per patient are required, which in a busy trauma center may represent 25% of a full-time employee. We hypothesized that International Classification of Disease-Ninth Revision (ICD-9) codes generated by the hospital information system (HI) would be similar to those coded by a dedicated trauma registrar (TR) and would be as accurate as TR ICD-9 codes in predicting outcome. ⋯ We conclude that in our hospital TR data on individual injuries can be replaced by HI data without loss of predictive power. ISS based on the MacKenzie dictionary should be abandoned because it is much less predictive of outcome than ICISS.
