Area of Science:

  • Health Services Research
  • Public Health
  • Health Economics

Background:

  • Conflicting 1970s studies debated physician service utilization disparities between poor and nonpoor populations.
  • Previous research indicated potential elimination of healthcare access gaps.
  • This study addresses persistent questions regarding socioeconomic disparities in healthcare access.

Purpose of the Study:

  • To re-examine ambulatory care utilization differences between poor and nonpoor populations using updated data and methods.
  • To assess the impact of health status on physician service use across poverty levels.
  • To investigate the mitigating role of Medicaid coverage on poverty-related healthcare access barriers.

Main Methods:

  • Analysis of a large sample (92,737 individuals) from the 1982 National Health Interview Survey.
  • Application of a refined analytical approach to compare physician contact rates.
  • Multivariate regression to control for health status and insurance coverage.

Main Results:

  • Unadjusted analysis showed no significant difference in physician contacts between poverty groups.
  • Health status adjustment revealed significantly fewer physician contacts for the poor.
  • Medicaid coverage was found to neutralize the negative impact of poverty on physician utilization.

Conclusions:

  • Poverty, even after accounting for health status, is associated with reduced physician service use.
  • Medicaid plays a crucial role in mitigating socioeconomic disparities in healthcare access.
  • Limited Medicaid coverage in 1982 highlights policy implications for eligibility criteria to improve access for the poor.
