Insurance status and access to health services among poor persons

Area of Science:

• Health Services Research
• Health Economics
• Public Health Policy

Background:

• Access to healthcare is a critical determinant of health outcomes, particularly for low-income populations.
• Understanding the role of health insurance status in facilitating or hindering care access is essential for effective health policy.
• Previous research has indicated disparities in care access among different socioeconomic groups.

Purpose of the Study:

• To investigate the relationship between health insurance status and access to medical care among low-income individuals under 65.
• To analyze how social demographics and healthcare needs influence this relationship.
• To compare access to care for individuals with Medicaid, private insurance, and no insurance.

Main Methods:

• Utilized data from the 1983, 1984, and 1986 Health Interview Surveys (HIS).
• Focused on subsamples of individuals at or below the federal poverty level and those between 100-150% of the poverty level.
• Measured access to care through annual physician visits and hospitalizations, controlling for health status and social characteristics.

Main Results:

• Medicaid coverage was significantly associated with higher utilization of both ambulatory and hospital care among the poor, compared to private insurance or being uninsured.
• Similar, though less pronounced, trends were observed for the near-poor population.
• These access differences persisted regardless of individuals' health status or risk of requiring medical care.

Conclusions:

• The findings suggest that cost-sharing mechanisms like copayments and deductibles in private insurance limit access for the poor and near-poor.
• Policy implications arise concerning the effectiveness of employer-sponsored insurance ('play or pay') and tax deductions in improving healthcare access.
• Targeted insurance strategies may be necessary to ensure equitable access to care for vulnerable populations.
