To obtain expected mortality for calculation of observed to expected (O/E) mortality ratios, a predictive mortality model was developed using a previously published model from the Trauma Quality Improvement Project (TQIP). Multiple imputation using a fully conditional specification model based on available demographics, prehospital and admission physiology, and injury characteristics with a successive impute and predict algorithm for each imputed variable and predict algorithm for non-imputed variables was performed using a single imputation step to develop a complete dataset. To address missing data, multiple imputation was performed for age, injury severity score (ISS), initial systolic blood pressure (SBP), heart rate (HR), Glasgow Coma Score (GCS) motor component, head abbreviated injury score (AIS), and abdominal AIS. Demographics, injury characteristics, and outcomes were collected. Centers that were both state designated and ACS verified were analyzed as ACS verified centers. The National Trauma Databank (NTDB) from 2007 to 2008 was queried for all patients в‰Ґ 16 years old admitted to an ACS verified level I or level II trauma center, or a state designated level I or level II trauma center that did not attain ACS verification.

The study hypothesis was that ACS verification would improve mortality on a larger scale when compared with state only designated centers. The study objective was to evaluate differences in mortality for ACS verified trauma centers as compared to state designated trauma centers without ACS verification from a national perspective. 21 To date, however little evidence is available characterizing differences in outcomes for trauma centers that attain ACS verification compared to those that operate with state designation only. 9, 18вЂ“ 20 The ACS is currently in the process of moving toward outcome evaluation a part of the verification process. 17ДЄCS verification among trauma centers has been supported by single center experience demonstrating improvements in outcomes and efficiency with achievement of ACS verification. This includes standards for center designation, which are often modeled after ACS verification criteria, however regional variation in designation standards make benchmarking difficult across centers. Trauma system development has occurred primarily at the state level, and most have legislation that designates trauma centers within the state network of hospitals. 15, 16 The ACS verification process is considered by many to be the highest attainable standard by a trauma center. The process of obtaining trauma center verification is rigorous and demands significant financial and resource support from hospitals. 6, 7 More recent data consistently support the benefits realized from maturing trauma systems in the United States, 8вЂ“ 13 and the ACS continues to refine the verification criteria and process. 2вЂ“ 5 Shortly thereafter the American College of Surgeons (ACS) began offering trauma center verification based on criteria set forth in the Resources for the Optimal Care of the Injured Patient. 1 Several landmark studies subsequently demonstrated dramatic improvements in outcomes after regionalization of trauma care. Development of trauma systems has become a priority since the recognition of serious deficiencies in the care of injured patients nearly fifty years ago.
