A letter report issued by the Government Accountability Office with an abstract that begins "GAO found that the number of advanced diagnostic imaging (ADI) services provided to Medicare beneficiaries in the office setting—an indicator of access to those services—began declining before and continued declining after the accreditation requirement went into effect on January 1, 2012. In particular, the rate of decline from 2009 to 2010 was similar to the rate from 2011 to 2012 for magnetic resonance imaging (MRI); computed tomography (CT); and nuclear medicine (NM), including positron emission tomography (PET) services. These results suggest that the overall decline was driven, at least in part, by factors other than accreditation. The percentage decline in the number of ADI services provided in the office setting was generally similar in both urban and rural areas during the period GAO studied."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has identified five additional risks since its November 2010 report ( GAO-11-103 ) associated with using new technologies in the National Nuclear Security Administration's (NNSA) Uranium Processing Facility (UPF), which is to be built in three interrelated phases. These risks and the steps that NNSA is taking to address them include the following:"

A letter report issued by the Government Accountability Office with an abstract that begins "Since Congress enacted the Military Housing Privatization Initiative (MHPI) in 1996, the military services conducted several analyses and considered other factors to determine whether to privatize housing for unaccompanied personnel. These analyses were conducted between 1997 and 2011. The Army's and the Navy's analyses compared different scenarios--such as whether to rely on privatization or use traditional military construction funding to improve housing quality--and considered information from multiple installations in these analyses. In contrast, the Air Force and Marine Corps analyzed the feasibility of privatizing unaccompanied housing at a few selected installations. For example, the Air Force based its initial analysis on information for two locations, while the Marine Corps based its 2008 analysis on information specific to one installation. The Navy and Army concluded that privatization could be used under a narrow set of circumstances at specific installations, such as where unaccompanied servicemembers were already receiving the basic allowance for housing (BAH). The Air Force and Marine Corps concluded that privatization was not suitable for meeting any of their housing needs. For example, an April 2000 Air Force memorandum indicated that privatization could have a negative …

Correspondence issued by the Government Accountability Office with an abstract that begins "GAO provided an in-depth classified briefing to committee staff on the results of this review in January 2014. GAO briefed on the status of several on-going nuclear command, control, and communications (NC3) modernization efforts within the Department of Defense (DOD), including progress made and remaining challenges to completing those efforts. GAO also reported on DOD's efforts to plan and develop the National Leadership Command Capability, a large initiative to integrate nuclear, senior leader, and continuity of government command, control, and communications capabilities and systems. Further details remain classified."

A letter report issued by the Government Accountability Office with an abstract that begins "For more than a decade, college prices have been rising consistently and have continued to rise at a gradual pace after the Stafford loan limit increases were enacted in 2008 and 2009. However, it is difficult to determine if a direct relationship exists between increases in college prices and the Stafford loan limit increases because of the confluence of many other factors that occurred around the time the loan limit increases took effect. Specifically, when the loan limit increases took effect, the nation was in a recession, which created one of the most tumultuous and complex economic environments in recent history. GAO's analysis found that the economic effects of the recession, which affected families' employment, income, and net worth make it difficult to isolate the impact the recession had on students' decisions to borrow money to finance college expenses versus the impact of the loan limit increases. Further, federal, state, and institutional aid available to students also increased significantly around the same time the loan limit increases went into effect. It is difficult to determine the extent to which the increased availability of this financial aid …
