title: Ectopic pregnancy rates and racial disparities in the Medicaid population, 2004-2008.
abstract: OBJECTIVE
  To assess 2004-2008 ectopic pregnancy rates among Medicaid recipients in 14 states and 2000-2008 time trends in three states and to identify differences in rate by race/ethnicity.
  
  
  METHODS
  Secondary analysis of Medicaid administrative claims data.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Women ages 15-44 enrolled in Medicaid in Arizona, California, Colorado, Florida, Illinois, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, New York, or Texas in 2004-2008 (n = 19,135,106) and in California, Illinois, and New York in 2000-2003.
  
  
  METHODS
  None.
  
  
  METHODS
  Number of ectopic pregnancies divided by the number of total pregnancies (spontaneous abortions, induced abortions, ectopic pregnancies, and all births).
  
  
  RESULTS
  The 2004-2008 Medicaid ectopic pregnancy rate for all 14 states combined was 1.40% of all reported pregnancies. Adjusted for age, the rate was 1.47%. Ectopic pregnancy incidence was 2.3 per 1,000 woman-years. In states for which longer term data were available (California, Illinois, and New York), the rate declined significantly in 2000-2008. In all 14 states, black women were more likely to experience an ectopic pregnancy compared with whites (relative risk, 1.46; 95% confidence interval, 1.45-1.47).
  
  
  CONCLUSIONS
  Ectopic pregnancy remains an important health risk for women enrolled in Medicaid. Black women are at consistently higher risk than whites.
