AbstractThe prehospital index (PHI) is a triage-oriented trauma severity scoring system. This prospective multicenter validation of the PHI was undertaken in response to a favorable pilot study. We applied the PHI to 3,581 patients from 14 different institutions during the period from January 1985 to February 1986. The PHI was accurate in predicting the need for emergency life-saving surgery within four hours (P less than .0001) and mortality within 72 hours (P less than .0001) following traumatic injury. The curves were generated for PHI versus emergency surgery, mortality, surgery and mortality, injury severity score, and ICU admission rate. These data compare favorably with those from previously published, prospectively tested, triage-oriented trauma severity scoring systems.
