A weak or absent palpable pulse correlates with a systolic blood pressure (SBP) of less than or equal to 100 mm Hg. Furthermore, the motor component of the Glasgow Coma Scale (GCS-M) has been shown to correlate with outcomes. In a previous study, the authors developed a simple triage tool, the field triage score (FTS), on the basis of pulse character and GCS-M status, which provided a quick and effective means of predicting injury survival in the civilian trauma environment. The purpose of this analysis was to validate the predictive utility of the FTS in the battlefield trauma environment. METHODS: The Joint Theater Trauma Registry was used to identify 4,988 battlefield casualties from Iraq and Afghanistan from January 2002 to September 2008 with requisite admission data elements of SBP, GCS-M status, and survival. SBP was stratified as less than or equal to 100 mm Hg, consistent with weak or absent pulse character, or greater than 100 mm Hg, consistent with a normal pulse character. GCS-M status was stratified as either abnormal (less than 6) or normal (6). Casualties with presenting SBPs of 0 mm Hg were excluded from the analysis. As in the civilian trauma triage study, the FTS was derived by assigning a component value of 0 for weak or absent pulse or abnormal GCS-M status and a component value of 1 for either a normal pulse or normal GCS-M status. Adding the scores resulted in an aggregate FTS value of 0, 1, or 2. 收起
