Is there a (volunteer) doctor in the house? Free clinics and volunteer physician referral networks in the United States.

Although community health centers and public hospitals are the most visible safety-net providers, physicians in private practice are the main source of care for the uninsured and Medicaid enrollees. Yet the number of these physicians providing free care is declining, even as the need for their services increases. One promising strategy for halting the decline is to strengthen and increase volunteer health care programs: free clinics and physician-referral networks.

Field building: lessons from the Robert Wood Johnson Foundation's anthology series.

As editors of the Robert Wood Johnson Foundation's (RWJF's) anthology series, we have examined the entire range of the foundation's grant making since 1972. We found that the RWJF has enjoyed considerable success in building fields--from nurse practitioners to tobacco control to end-of-life care. The RWJF has done this by shaping fields as they were emerging, by adopting a wide-ranging "bear hug" approach, and by staying the course.
