Abstract

Hypothesis: Similarly designated trauma centers do not achieve similar outcomes. Design: Outcomes study. Setting: Academic research. Participants: Forty-seven American College of Surgeons-verified level I trauma centers that contributed more than 1000 patients to the National Trauma Data Bank (from January 1999 to December 2003) were identified. Main Outcome Measures: Patients were classified into the following 3 injury severity groups using a combination of anatomical and physiological measures: mild (Injury Severity Score [ISS] of <25 with systolic blood pressure [SBP] of ≥90 mm Hg [n = 184 650]), moderate (ISS of ≥25 with SBP of ≥90 mm Hg or ISS of <25 with SBP of <90 mm Hg [n = 22 586]), and severe (ISS of ≥25 with SBP of <90 mm Hg [n = 4243]). The mean survival for each group was calculated. Individual centers were considered outliers if their patient survival was statistically significantly different from the mean survival for each severity group. Results: The mean survival of patients with mild, moderate, and severe injuries was 99%, 75%, and 35%, respectively. For mild injuries, survival at 5 centers (11%) was significantly worse than that at their counterpart centers. With increasing injury severity, the percentages of outcome disparities increased (15% of centers for moderate injuries and 21% of centers for severe injuries) and persisted in subgroups of patients with head injuries, patients sustaining penetrating injuries, and older (>55 years) individuals. Conclusions: When treating patients with similar injury severity, similarly designated level I trauma centers may not achieve similar outcomes, suggesting the existence of a quality chasm in trauma care. Trauma center verification may require the use of outcome measures when determining trauma center status.
