RT Journal A1 Mitka M T1 STudies comparing treatments ramp up JF JAMA JO JAMA YR 2009 FD May 20 VO 301 IS 19 SP 1975 OP 1975 DO 10.1001/jama.2009.671 UL http://dx.doi.org/10.1001/jama.2009.671 AB As rising health care costs continue to strain the Medicare and Medicaid budgets, the government has become interested in comparative effectiveness research, which promises to provide quality data about the costs and benefits of various treatment options. The economic gains that may derive from such study have caused some to question whether it will be used to justify health care rationing. But members of a federal council that will coordinate the research and make funding suggestions said they will not be recommending clinical guidelines for payment, coverage, or treatment.
