ObjectiveThe purpose of this study was to compare the impact of trauma patient outcomes before and after Level II American College of Surgeons (ACS) verification was received in a not-for-profit community hospital.MethodsThis was a retrospective analysis of hospital discharge data for timeframes before and after Level II ACS verification was conducted. Originally, 8,674 patients were identified using the International Classification of Diseases, 9th Revision codes for trauma. These data were parsed to 7,811 patients by using International Classification of Diseases, 9th Revision codes 800 xx through 959.9 x, which signify an admitting diagnosis of trauma; 3,835 of the patients were admitted after the July 28, 1998, verification date. Blunt injuries constituted the vast majority of the patients (n = 7,488). Outcome measures studied included changes in length of stay (LOS), mortality, and total cost. Internal control was coronary artery bypass graft patients at the same hospital, and external control was trauma patients at a non-ACS hospital over the same time period. Data are presented with p values and SE and the ratio of observed/expected values on the basis of the all-payer severity-adjusted diagnosis-related group severity model.ResultsThe two timeframes exhibited statistically different outcomes in several variables. Adjusting for severity postverification, LOS was 10% less (p < 0.000). Similarly, severity-adjusted mortality observed/expected ratios were significantly different: 0.81 before versus 0.59 after (p < 0.000). The severity-adjusted ratio of costs found that the postverification era was 5% lower (p < 0.000). The contribution margin of the trauma patient population to the hospital well exceeded any postverification costs. Both control groups exhibited no significant changes in their severity-adjusted outcomes, which could have invalidated these results.ConclusionThis study suggests that the efforts and resources consumed achieving ACS Level II trauma center verification appear to result in desired outcomes as evidenced by decreased LOS, reduced in-hospital mortality rates, reduced cost, and improved contribution margins.
