  1. Abbreviations: AMI, acute myocardial infarction; CHF, congestive heart failure; CI, confidence interval; FFS, fee for service; OR, odds ratio
  2. aPatient characteristics were age, sex, All Patient Refined-Diagnosis Related Group (APR-DRG), and community income
  3. bHospital characteristics were bed size, ownership, teaching status, and urban/rural location
  4. cA down arrow indicates the mortality rate for managed care is significantly lower than FFS at p < 0.05. An up arrow indicates the mortality rate for managed care is significantly higher than FFS at p < 0.05
