title: Centers for Medicare and Medicaid services quality indicators do not correlate with risk-adjusted mortality at trauma centers.
abstract: OBJECTIVE
  The Centers for Medicare and Medicaid Services (CMS) publicly reports hospital compliance with evidence-based processes of care as quality indicators. We hypothesized that compliance with CMS quality indicators would correlate with risk-adjusted mortality rates in trauma patients.
  
  
  METHODS
  A previously validated risk-adjustment algorithm was used to measure observed-to-expected mortality ratios (O/E with 95% confidence interval) for Level I and II trauma centers using the National Trauma Data Bank data. Adult patients (>or=16 years) with at least one severe injury (Abbreviated Injury Score >or=3) were included (127,819 patients). Compliance with CMS quality indicators in four domains was obtained from Hospital Compare website: acute myocardial infarction (8 processes), congestive heart failure (4 processes), pneumonia (7 processes), surgical infections (3 processes). For each domain, a single composite score was calculated for each hospital. The relationship between O/E ratios and CMS quality indicators was explored using nonparametric tests.
  
  
  RESULTS
  There was no relationship between compliance with CMS quality indicators and risk-adjusted outcomes of trauma patients.
  
  
  CONCLUSIONS
  CMS quality indicators do not correlate with risk-adjusted mortality rates in trauma patients. Hence, there is a need to develop new trauma-specific process of care quality indicators to evaluate and improve quality of care in trauma centers.
