An analysis carried out by researchers at the Geiger Gibson/RCHN Community Health Foundation Research Collaborative at the George Washington University Milken Institute School of Public Health (Milken Institute SPH) shows that health centers served over 350,000 CHIP beneficiaries in 2013, one in twenty-five CHIP beneficiaries that year. In certain states however, community health centers cared for anywhere from 10 to 38 percent of patients enrolled in CHIP.
