title: Access to hospitals with high-technology cardiac services: how is race important?
abstract: OBJECTIVE
  Relatively few hospitals in the United States offer high-technology cardiac services (cardiac catheterization, bypass surgery, or angioplasty). This study examined the association between race and admission to a hospital offering those services.
  
  
  METHODS
  Records of 11,410 patients admitted with acute myocardial infarction to hospitals in New York State in 1986 were analyzed.
  
  
  RESULTS
  Approximately one third of both White and Black patients presented to hospitals offering high-technology cardiac services. However, in a multivariate model adjusting for home-to-hospital distance, the White-to-Black odds ratio for likelihood of presentation to such a hospital was 1.68 (95% confidence interval = 1.42, 1.98). This discrepancy between the observed and "distance-adjusted" probabilities reflected three phenomena: (1) patients presented to nearby hospitals; (2) Blacks were more likely to live near high-technology hospitals; and (3) there were racial differences in travel patterns. For example, when the nearest hospitals did not include a high-technology hospital, Whites were more likely than Blacks to travel beyond those nearest hospitals to a high-technology hospital.
  
  
  CONCLUSIONS
  Whites and Blacks present equally to hospitals offering high-technology cardiac services at the time of acute myocardial infarction. However, there are important underlying racial differences in geographic proximity and tendencies to travel to those hospitals.
