RT Journal A1 McConnel C T1 A free clinic paradox JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2011 FD April 25 VO 171 IS 8 SP 782 OP 790 DO 10.1001/archinternmed.2011.143 UL http://dx.doi.org/10.1001/archinternmed.2011.143 AB Darnell has presented a detailed report of her major national survey of free clinics and an illuminating discussion of how vital this asset is as a component of the nation's health care “safety net.”1 Yet considering the enormous resource base of this fine but relatively obscure national health care asset—its thousand or so clinics and countless hours of professional and semiprofessional volunteer health care providers plus paid staff and in-kind community-based contributions—what comes to mind is the economists' major inconvenient truth, “there ain't no such thing as a free lunch.”
