The Center for the Study of Human Resources (Center), a research facility of the LBJ School of Public Affairs of the University of Texas at Austin, was requested by the Texas Department of Health (TDH) to assist in planning and evaluation activities associated with the delivery of Human Immunodeficiency Virus (HIV) services in Texas. The long-term goal of these activities, initiated in response to language contained in the federal Ryan White Comprehensive AIDS Resources Emergency Act of 1990 (CARE Act) and existing state legislation, focused on developing and implementing an evaluation of the cost effectiveness of services delivered to individuals with HIV disease through programs administered by TDH and funded with state and federal monies. The more immediate purpose of this report is to provide a baseline description of the emergent HIV service delivery system in Texas.
