title: The effect of a comprehensive Medicaid expansion on physicians' obstetric practices in Washington State.
abstract: BACKGROUND
  In 1989 Washington State implemented a comprehensive expansion of its Medicaid perinatal program, augmenting services, increasing provider reimbursement, and broadening eligibility. This study examines the influence of this legislation on physicians' obstetric practices and attitudes toward caring for pregnant Medicaid patients.
  
  
  METHODS
  Family physicians and obstetrician-gynecologists were surveyed at the start and 18 months after the Medicaid expansion. The study sample comprised physicians responding to the survey in both years.
  
  
  RESULTS
  A greater proportion of family physicians provided unlimited obstetric care to Medicaid patients after the expansion. Sixty percent of family physicians and 56 percent of obstetrician-gynecologists were more willing to provide prenatal care to Medicaid patients as a result of the expansion. Physicians and their office staff were more comfortable with Medicaid patients in the later time period. Many physicians felt that they were better able to link their patients to a variety of social services after the expansion.
  
  
  CONCLUSIONS
  A Medicaid expansion program can increase provider participation in Medicaid and increase provider comfort in caring for Medicaid patients.
