About


The Center for Healthcare Data houses several large datasets that cover health care utilization for over 65% of the Texas population. Data are made available for approved research studies designed to enhance and expand the body of knowledge regarding utilization of health care services, quality, costs, payment systems, and policy reform.

Within the center, the Blue Cross Blue Shield of Texas - University of Texas School of Public Health Payment Systems and Policy Research Program houses the BCBSTX dataset. The program was funded by a $1.5 million grant from BCBSTX. Researchers in the program work to foster research and inform the public, academia, and other constituents about health care costs and utilization with the goal of contributing to the discussion on improving efficiency and controlling health care costs in Texas.

Additionally, the Center for Health Care Research Data provides consultative and analytical services to the state of Texas, and has certification as a CMS Qualified Entity. Read more about CMS Qualified Entities here.
