What is the link between insurance coverage and health care access?

The Consequences of Being Uninsured

Research demonstrates that the uninsured:

• use fewer preventive and screening services;

• are sicker when diagnosed;

• receive fewer therapeutic services;

• have poorer health outcomes (higher mortality and disability rates); and

• have lower annual earnings because of poorer health.

• Review of four studies; 8 comparisons (4 of Hispanic-White disparities and 4 of African American-White disparities

• Seven of 8 comparisons show insurance coverage as the single largest factor explaining racial disparities in having a regular source of medical care

Disparity

Promising Strategies for Reducing HealthCare Disparities

• Increasing awareness of the problem

• Assuring adequate and meaningful health insurance coverage

• Improving healthcare quality through government regulatory and purchasing mechanisms

Figure 8

What Can Be Done To Improve Insurance Coverage

• Create a more uniform system of coverage that guarantees a defined benefit

• Expand the reach of the current mix of private and public coverage, while maintaining the scope of benefits

Figure 9

What Can Be Done To Improve Coverage & Reduce Disparities

• Nearly three-quarters of the 23 million uninsured persons of color have family incomes below 200% of poverty

• Many, therefore, would qualify for Medicaid or S-CHIP

• Policy Options - expand outreach and enrollment efforts to ensure that all

eligible children are enrolled in Medicaid and S-CHIP

- expand coverage to parents of enrolled children

- expand coverage to low-income adults without dependent children

Figure 10

Challenges and Opportunities

• Perceptions on the scope and nature of the problem vary

• Health costs continuing to rise

• Public resources limited (federal deficits, state budget crises)

• Lack of political will to implement best evidence
