Using nationally representative data from 2 major surveys in 2002, there was a positive association between seeking care in community health centers and self-reported access to care for both uninsured and Medicaid patients. This suggests that health centers may fill a critical gap in access to care for patients who use their services. Given recent budget cuts to the Medicaid program, health centers remain an important policy option to assure access to care for vulnerable populations. © 2007 Lippincott Williams & Wilkins, Inc.
