RT Journal A1 Sessions SY, Detsky AS T1 THe “shadow government” in health care JF JAMA JO JAMA YR 2010 FD December 22 VO 304 IS 24 SP 2742 OP 2743 DO 10.1001/jama.2010.1873 UL http://dx.doi.org/10.1001/jama.2010.1873 AB Because of a combination of economic, social, and legal factors, considerable power over health care has effectively been delegated to medical societies, research organizations, and other institutions, enabling them to function in some respects like government rather than agents in a free market. In particular, the issuance of official statements setting the criteria for the diagnosis and treatment of disease can have much the same effect as the enactment of legislation or promulgation of regulations. In this Commentary, we describe how this “shadow government” evolved and discuss some of the implications of this phenomenon for health policy.
