In this 2003 to 2005 project, researchers from the Urban Institute examined the dynamics of health insurance coverage and public health insurance eligibility from 1996 to 2000 and assessed the impact of public policy and economic changes on coverage.
Their analysis included enrollment in the State Children's Health Insurance Program (CHIP) to determine whether increases in program participation reflected access to new coverage or substitution of public coverage for private.
This project was part of the Robert Wood Johnson Foundation (RWJF) national program Changes in Health Care Financing and Organization (HCFO). HCFO supports policy analysis, research, evaluation and demonstration projects that provide public and private decision leaders with usable and timely information on health care policy and financing issues.
The researchers reported the following findings:
- There is minimal evidence that eligibility for public health insurance produced substantial reductions in private coverage and compelling evidence of decreases in uninsurance.
- Children who were uninsured but became eligible for public health insurance through CHIP were likely to have remained uninsured if not for CHIP implementation.
