The Government Accountability Office (GAO) has issued a report entitled "HHS Research Awards: Use of Recovery Act and Patient Protection and Affordable Care Act Funds for Comparative Effectiveness Research." The report includes a more than 40-page listing of all comparative effectiveness research grants issued under the Recovery Act, including the entities that have received funding and the general purpose of the funding (no funding had been obligated under the ACA's comparative effectiveness provision as of April 25, 2011).
