How federal and state policies affected hospital uncompensated care provision in the 1990s.

The 1990s featured pronounced policy change that had important effects on safety net providers and their ability to care for the uninsured. The authors examined how changes in public policy affected hospital uncompensated care (UC) between 1990 and 2000. They found that aggregate state Medicaid Disproportionate Share Hospital spending had no impact on UC provision. Expanding public health insurance eligibility for children and adults and increasing Medicaid managed care had small negative effects on UC provision. State and local tax appropriations had the largest impact on UC provision. A better understanding of the effect of health care policies on UC provision is essential in crafting new policies and better anticipating their impact.
