Changes in the health care safety net 1992-2003: disparities in access for uninsured persons in Florida

A patchwork of services is available to uninsured in the United States through the health care safety net. During 1996-2003, some safety net hospitals (SNHs) closed or converted their ownership status from public or non-profit to for-profit. Meanwhile, the number of community health centers (CHCs) grew as a result of new federal funding. This article examines the impact of these two countervailing events on access to care for the uninsured. Hospital admissions for ambulatory care sensitive conditions relative to marker conditions were used as our access measure. We examined 35,730 discharges for uninsured adults treated in Florida hospitals in the years 1992 or 2003. A generalized estimating equation model was used to assess differential access effects for racial and ethnic groups. We found that in communities with CHC openings but no SNH contractions, uninsured black and white individuals experienced deteriorations in access over time, but the Hispanic uninsured did not. However, in communities where SNHs closed or converted, access deteriorations occurred for all three racial and ethnic groups. Thus, the potentially beneficial effects of CHC expansions on access to primary care for the uninsured Hispanic population in Florida appeared to be offset if contractions in the hospital safety net were present.
