ObjectiveBy using mandatory discharge data from a state agency, the records of 116,687 patients hospitalized for treatment of injury were evaluated to develop an epidemiologic and demographic profile of this population and to compare outcomes of patients treated in state-designated trauma centers (TC) with those treated in nontrauma centers (NTC).MethodsInjury severity was calculated by using the International Classification Injury Severity Score methodology to compute individual diagnosis survival risk ratios from 698,187 reported diagnoses, and then by using these survival risk ratios to determine probability of survival for every patient. The population was then categorized by age, injury type, treatment facility designation, injury severity as indicated by probability of survival, and discharge disposition. Incidence of potentially preventable death was compared between TC and NTC, as was the effect on outcome of noninjury comorbidity.ResultsThe average age of this population was 58 +/- 26 years with significant skew toward the elderly in NTC (mean age, 62 +/- 26 years). The most commonly encountered injuries likewise reflected the elderly nature of this population. Although 71.3% received care in NTC, the majority of severely injured were treated in TC. Potentially preventable mortality (>0.5) was significantly lower in TC. The effect of noninjury comorbidity on outcome was better managed by TC, both in terms of decreased mortality and in proportion of patients discharged home.ConclusionThese data demonstrate the unique characteristics of injury victims treated in the state of Florida and indicate that the developing trauma system is demonstrating productivity in terms of avoidance of preventable death, efficient management of noninjury comorbid problems, and more complete recovery as indicated by proportion of patients discharged to home.
