BackgroundTrauma is viewed by many as a global problem. The phenomenon of similar outcomes within differing healthcare delivery systems can illuminate the strengths and weaknesses of various trauma systems as well as the effects of these characteristics on patient outcome.ObjectivesTo compare and contrast demographic and injury characteristics as well as patient outcomes of two urban/suburban trauma centers, one in Israel and the other in the United States.MethodsStudy data were obtained from the trauma registries of two trauma centers. Demographic variables, injury characteristics and outcomes were compared statistically between registries.ResultsSignificant differences between the registries were found in demographic variables (age), injury characteristics (Injury Severity Score and mechanism of injury), and outcome (mortality and length of stay). Age and Injury Severity Score were found to be significant predictors of outcome in both registries. The Glasgow Coma Score was found to contribute to patient outcomes more than the ISS. Differences were found in the relative impact of injury and demographic factors on outcomes between the registries. After including the influence of these factors on patient outcomes, significant differences still remained between the outcomes of the trauma centers.ConclusionsDespite possible explanations for these differences, true comparisons between centers are problematic.
