Variability in trauma center outcomes for patients with moderate intracranial injury.
The variability of outcome between Trauma Centers has not been extensively studied as a possible avenue for performance improvement. Trauma Center variability in severity-adjusted survival for patients with moderate intracranial injury (MII) was studied in order to determine the association of MII-related process of care variables with outcomes. The analytic results were supplemented with peer review of MII patients with unexpected outcomes and identified potential process of care variables. ⋯ Two severity adjustment methods identified significant variability in trauma center outcomes for patients with MII. The difference in outcomes between the centers with better than expected (2PZW) and poorer than expected outcomes (3NZW) was substantial. Peer review identified significant opportunities for reducing unexpected deaths, stays in hospital and in ICU, and the occurrence of complications. Trauma registry data and peer reviews found little relationship between available process of care variables and patient outcomes. This study should stimulate discussions to understand reasons for outcome variability and ways to reduce it.
