Translating research to action: improving physician access in public insurance.

Policymakers continue to struggle with how to assure adequate access to physician services in public programs like Medicaid, State Children's Health Insurance Program, or other public coverage programs. In this article, we synthesize available research on this topic and provide a framework that policymakers may find useful in identifying and measuring barriers to care access, determining where and why problems exist, and identifying how to intervene. Using our experience constructing the framework, we also consider what observations can be drawn from this experience for those interested in the challenge of moving the insights from research to practice.
