VA Medical Centers: Further Operational Improvements Could Enhance Third-Party  Collections (open access)

VA Medical Centers: Further Operational Improvements Could Enhance Third-Party Collections

A letter report issued by the Government Accountability Office with an abstract that begins "In the face of growing demand for veterans' health care, GAO and the Department of Veterans Affairs Office of Inspector General (OIG) have raised concerns about the Veterans Health Administration's (VHA) ability to maximize its third-party collections to supplement its medical care appropriation. GAO has testified that inadequate patient intake procedures, insufficient documentation by physicians, a shortage of qualified billing coders, and insufficient automation diminished VA's collections. In turn, the OIG reported that VA missed opportunities to bill, had billing backlogs, and did inadequate follow-up on bills. While VA has made improvements in these areas, GAO was asked to review internal control activities over third-party billings and collections at selected medical centers to assess whether they were designed and implemented effectively."

Information on Options for Naval Surface Fire Support

Correspondence issued by the Government Accountability Office with an abstract that begins "Land-, air-, and sea-based components form the "fires triad" that is used to support Marine Corps amphibious assault operations. The sea-based part of the fires triad is referred to as Naval Surface Fire Support (NSFS). The retirement of the last Iowa class battleship left a void in the NSFS part of the fires triad. To field a replacement NSFS capability, the Navy developed a two-phased plan in 1994. In the near-term to midterm, it would modify the capability of 5-inch guns on existing destroyers and cruisers, and develop extended-range guided munitions for the modified 5-inch gun. In the far term, it would field a sufficient number of new destroyers fitted with an even-longerrange advanced gun system and ultimately a very-long-range electromagnetic gun or "Rail Gun." However, in 1996, congressional authorizers became concerned that the Navy would not be able to produce a replacement NSFS capability comparable to the battleships until well into the twenty-first century. In that year's Defense Authorization Act, the Congress directed the Secretary of the Navy to restore at least two Iowa class battleships to the naval vessel registry until a capability was developed equal …

Veterans Benefits: VA Needs Plan for Assessing Consistency of Decisions (open access)

Veterans Benefits: VA Needs Plan for Assessing Consistency of Decisions

A letter report issued by the Government Accountability Office with an abstract that begins "In the past, we have reported concerns about possible inconsistencies in the disability decisions made by the 57 regional offices of the Department of Veterans Affairs (VA). In 2002, we reported that VA did not systematically assess the consistency of decision making for any specific impairments included in veterans' disability claims. We recommended that VA conduct such assessments to help reduce any unacceptable variations that VA might find among regional offices. VA agreed that decision-making consistency is an important goal and concurred in principle with our recommendation. However, VA did not discuss how it would measure consistency. In January 2003, in part because of concerns about consistency, we designated VA's disability program, along with other federal disability programs, as high-risk. In fiscal year 2005, VA estimates it will pay about $25 billion in disability compensation benefits to about 2.7 million disabled veterans. In this context, we determined (1) the actions that VA has taken to assess the consistency of regional office decisions on disability compensation claims and (2) the extent to which VA program data can be used to measure the consistency of decision making among …

Child Support Enforcement: Better Data and More Information on Undistributed Collections Are Needed

A letter report issued by the General Accounting Office with an abstract that begins "Congress established the child support enforcement program in 1975 to ensure that parents financially supported their children. State agencies administer the program and the Office of Child Support Enforcement (OCSE) in the Department of Health and Human Services oversees it. In 2002, state agencies collected over $20 billion in child support, but $657 million in collections from 2002 and previous years were undistributed--funds that were delayed or never reached families. One method used to collect child support, intercepting federal tax refunds, involves all state agencies, OCSE, and two Department of the Treasury agencies--the Internal Revenue Service (IRS) and the Financial Management Service (FMS). GAO was asked to address (1) how the total amount of undistributed collections changed over the years, (2) the causes of undistributed collections, (3) states' efforts to reduce these funds, and (4) OCSE's efforts to assist states. GAO analyzed OCSE data, administered a survey, visited 6 state agencies and interviewed officials."

Multifamily Housing: Implementation of Fiscal Year 2003 Requirements Concerning Housing Choice Voucher Administrative Fees (open access)

Multifamily Housing: Implementation of Fiscal Year 2003 Requirements Concerning Housing Choice Voucher Administrative Fees

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Housing and Urban Development (HUD) received $12.9 billion in fiscal year 2003 for the Housing Choice Voucher Program, which helps about 2 million low-income families pay rent for privately owned housing. This amount included $1.1 billion in administrative fee payments to the public housing agencies that administer the program for HUD. In the Consolidated Appropriations Resolution of 2003, Congress included provisions to address a concern that housing agencies may have received more in fees than they needed to run the program. Housing agencies were directed to report to HUD their available reserves as of January 31, 2003. HUD was directed to reduce the fees agencies would receive if these levels were too high and recapture some excess fees. The conference report accompanying the Consolidated Appropriations Act of 2004 directed GAO to review compliance with these provisions. This report discusses (1) the extent to which housing agencies complied with the requirement to report to HUD their available administrative fee reserves as of January 31, 2003; (2) how these reported reserves compared with reserves reported in earlier fiscal years and possible reasons for any declines; …

Workplace Safety and Health: OSHA's Voluntary Compliance Strategies Show Promising Results, but Should be Fully Evaluated Before They Are Expanded

A letter report issued by the General Accounting Office with an abstract that begins "Because the Occupational Safety and Health Administration (OSHA) can inspect only a fraction of 7 million U.S. worksites each year in its efforts to ensure safe and healthy working conditions, the agency has increasingly supplemented enforcement with "voluntary compliance strategies" to reach more employers and employ its resources most effectively. GAO assessed the types of strategies used, the extent of their use, and their effectiveness. GAO also obtained suggestions from specialists for additional voluntary compliance strategies."

Military Operations: DOD's Extensive Use of Logistics Support Contracts Requires Strengthened Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "In its contingency operations since the early 1990s, the Department of Defense (DOD) has relied extensively on logistics support contractors to provide many of the supplies and services needed by deployed U.S. forces. As requested, GAO assessed DOD's planning in its use of logistics support contracts in contingency operations; determined whether DOD has had contract oversight processes that are adequate to ensure that quality services were provided in an economical and efficient manner; and assessed the extent to which DOD provided trained personnel qualified to oversee its contractors. GAO focused its efforts on four logistics support contracts chosen because of their size and chosen to represent more than one military service--the Army's Logistics Civil Augmentation Program (LOGCAP) and Balkans Support Contract, the Navy's Construction Capabilities Augmentation Program, and the Air Force's Contract Augmentation Program."

Aviation Security: Preliminary Observations on TSA's Progress to Allow Airports to Use Private Passenger and Baggage Screening Services

A letter report issued by the Government Accountability Office with an abstract that begins "Beginning on November 19, 2004, the Transportation Security Administration (TSA) is required by law to begin allowing commercial airports to apply to use private contractors to screen passengers and checked baggage. A federal workforce has performed this work since November 2002, in response to a congressional mandate that the federal government take over screening services after the terrorist attacks of September 11, 2001. A 2-year pilot program at five airports testing the effectiveness of private sector screening in a post-September 11 environment concluded on November 18, 2004. This report contains GAO's preliminary observations related to TSA's progress in developing a private-sector screening program that allows airports to apply to opt out of using federal screeners. GAO assessed: (1) the status of TSA's efforts to develop policies and procedures for the opt-out program, including operational plans and guidelines for selecting airports and contractors that may participate; (2) guidance about the opt-out program that TSA has provided to airport operators and other stakeholders, or plans to develop, and how the information is communicated; and (3) TSA's efforts to develop performance measures for evaluating the opt-out program and contractor …

Tobacco Settlement: States' Allocations of Fiscal Year 2003 and Expected Fiscal Year 2004 Payments

A letter report issued by the General Accounting Office with an abstract that begins "In the 1990s, states sued major tobacco companies to obtain reimbursement for health impairments caused by the public's use of tobacco. In 1998, 46 states and four of the nation's largest tobacco companies signed a Master Settlement Agreement (MSA) that requires the tobacco companies to make annual payments to the states in perpetuity as reimbursement for past tobaccorelated health care costs. The MSA commits the tobacco companies to pay the states approximately $206 billion over the first 25 years. Some of the states have arranged to receive upfront proceeds based on the amounts that tobacco companies owe by issuing bonds backed by future payments. The Farm Security and Rural Investment Act of 2002 requires GAO to report annually on the amount of MSA payments states receive through fiscal year 2006. This third report provides information on the payments the 46 states received in fiscal year 2003 and expect to receive in fiscal year 2004, and states' allocations of these funds to various program categories and changes from prior years. To conduct this study, GAO surveyed the 46 states."

Defense Acquisitions: Space-Based Radar Effort Needs Additional Knowledge before Starting Development

A letter report issued by the Government Accountability Office with an abstract that begins "Missing among the Department of Defense's (DOD) portfolio of systems is a capability to track stationary and moving enemy vehicles on land or at sea in any type of weather, day or night, from space. To meet this need, DOD and the intelligence community are collaborating on the ambitious Space-Based Radar (SBR) program. By leveraging the newest generation of radar technologies, the SBR concept promises to deliver high-quality data to a wide array of users. DOD intends to start product development in 2006 and to field SBR satellites as quickly as possible so that warfighters, the intelligence community, and national decision makers can gain a better understanding of what adversaries are doing in specific locations around the world. GAO reviewed the SBR program to assess DOD's progress in attaining the knowledge it needs by 2006 in terms of customer needs (or requirements) and resources."

Endangered Species: Federal Agencies Have Worked to Improve the Consultation Process, but More Management Attention Is Needed

A letter report issued by the General Accounting Office with an abstract that begins "To protect species that are at risk for extinction, the Endangered Species Act requires that federal agencies consult with the Fish and Wildlife Service or the National Marine Fisheries Service (the Services) to ensure that activities they authorize, fund, or conduct will not jeopardize endangered species or adversely modify their critical habitat. While federal agencies recognize that consultations benefit species, some are concerned about the time and resources consumed. In this report, GAO (1) assesses the federal data on consultations, (2) identifies steps by federal agencies to improve the process, and (3) discusses lingering concerns of federal and nonfederal parties about the process. GAO limited this study to consultations with the Forest Service, the U.S. Army Corps of Engineers, and the Bureaus of Land Management and Reclamation in Idaho, Montana, Oregon, and Washington."

Military Housing: Further Improvement Needed in Requirements Determinations and Program Review

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) plans to spend about $9.8 billion in fiscal year 2004 to provide housing for about 711,000 families of activeduty military personnel in the United States. DOD's policy for some time has been to rely on housing in the local communities and provide military-owned or privatized military housing when the communities cannot satisfy requirements. Historically, DOD has viewed private sector housing as more cost-effective. In January 2003, DOD approved a revised housing requirements determination process designed to provide a solid basis for justifying on-base family housing needs. GAO looked at whether (1) reliance on community housing remains costeffective, (2) the revised process has resulted in consistent and reliable needs assessments, and (3) DOD's top-level review of military housing construction proposals could be improved."

Nuclear Nonproliferation: DOE Needs to Consider Options to Accelerate the Return of Weapons-Usable Uranium from Other Countries to the United States and Russia

A letter report issued by the Government Accountability Office with an abstract that begins "Many foreign nuclear research reactors use highly enriched uranium (HEU) fuel. Because HEU can be used in nuclear weapons, the Department of Energy (DOE) has two programs to return HEU from foreign reactors to either the United States or Russia. The U.S. fuel acceptance program includes HEU exported by the United States to 34 countries, 11 of which have returned all of their HEU. The program also includes low enriched uranium (LEU) fuel, which would be very difficult to use in a nuclear weapon. DOE imposes a fee on high-income countries to partially offset the cost of disposing of HEU and LEU fuel in the United States. Under the Russian fuel return program, DOE assists in the return of Russian-origin HEU from 14 countries to Russia. GAO was asked to examine (1) the status of DOE efforts to recover remaining inventories of U.S.-origin HEU and the extent to which the fees imposed on high-income countries support these efforts, and (2) the cost and time frame for completing the Russian fuel return program."

Space Shuttle: Costs for Hubble Servicing Mission and Implementation of Safety Recommendations Not Yet Definitive

A letter report issued by the Government Accountability Office with an abstract that begins "Hubble's continued operation has been dependent on manned servicing missions using the National Aeronautics and Space Administration's (NASA) shuttle fleet. The fleet was grounded in early 2003 following the loss of the Space Shuttle Columbia, as NASA focused its efforts on responding to recommendations made by the Columbia Accident Investigation Board (CAIB). In January 2004, NASA announced its decision to cancel the final planned Hubble servicing mission, primarily because of safety concerns. Without some type of servicing mission, NASA anticipates that Hubble will cease to support scientific investigations by the end of the decade. NASA's decision not to service the Hubble prompted debate about potential alternatives to prolong Hubble's mission and the respective costs of these alternatives. This report addresses the basis of NASA's cost estimates to (1) service Hubble using the shuttle and (2) implement recommendations made by the CAIB. GAO is continuing its work on the Congressional request that GAO examine the potential cost of a robotic servicing mission to the Hubble Telescope."

Information Technology: The Federal Enterprise Architecture and Agencies' Enterprise Architectures Are Still Maturing

Testimony issued by the General Accounting Office with an abstract that begins "The concept of enterprise architecture emerged in the mid- 1980s as a means for optimizing integration and interoperability across organizations. In the early 1990s, GAO research of successful public and private sector organizations led it to identify enterprise architecture as a critical success factor for agencies that are attempting to modernize their information technology (IT) environments. Since then, GAO has repeatedly identified the lack of an enterprise architecture as a key management weakness in major modernization programs at a number of federal agencies. It has also collaborated with the Office of Management and Budget (OMB) and the federal Chief Information Officers (CIO) Council to develop architecture guidance. In 2002, OMB began developing the Federal Enterprise Architecture (FEA), an initiative intended to guide and constrain federal agencies' enterprise architectures and IT investments. GAO was asked to testify on the status of the FEA and on the state of federal agencies' development and use of enterprise architectures."

National Aeronautics and Space Administration: Significant Actions Needed to Address Long-standing Financial Management Problems

Testimony issued by the General Accounting Office with an abstract that begins "Congress asked GAO to testify on the status of the National Aeronautics and Space Administration's (NASA) financial management reform efforts. NASA faces major challenges that if not addressed, will weaken its ability to manage its highly complex programs. NASA has been on GAO's high-risk list since 1990 because of its failure to effectively oversee its contracts and contractors, due in part to the agency's lack of accurate and reliable information on contract spending. GAO's statement focused on (1) how NASA's history of clean audit opinions served to mask the true extent of the agency's financial management difficulties; (2) the results of NASA's fiscal year 2003 financial statement audit, which are a departure from the fiscal year 2002 results; (3) NASA's effort to implement an integrated financial management system; and (4) the challenges NASA faces in reforming its financial management organization. Although GAO does not make specific recommendations in this statement, GAO previously made several recommendations to improve NASA's acquisition and implementation strategy for its financial management system. While NASA ultimately agreed to implement all of the recommendations, it disagreed with most of the findings--stating that its acquisition and …

Computer-Based Patient Records: Improved Planning and Project Management Are Critical to Achieving Two-Way VA-DOD Health Data Exchange

Testimony issued by the General Accounting Office with an abstract that begins "Providing readily accessible health information on veterans and active duty military personnel is highly essential to ensuring that these individuals are given quality health care and assistance in adjudicating disability claims. Moreover, ready access to health information is consistent with the President's recently announced intention to provide electronic health records for most Americans within 10 years. In an attempt to improve the sharing of health information, the Departments of Veterans Affairs (VA) and Defense (DOD) have been working, since 1998, toward the ability to exchange electronic health records for use by veterans, military personnel, and their health care providers. In testimony before Congress last November and again this past March, GAO discussed the progress being made by the departments in this endeavor. While a measure of success has been achieved--the one-way transfer of health data from DOD to VA health care facilities--identifying the technical solution for a two-way exchange, as part of a longer term HealthePeople (Federal) initiative, has proven elusive. At Congress's request, GAO reported on its continuing review of the departments' progress toward this goal of an electronic two-way exchange of patient health records."

Aviation Security: Challenges in Using Biometric Technologies

Testimony issued by the General Accounting Office with an abstract that begins "One of the primary functions of any security system is the control of people moving into or out of protected areas, such as physical buildings, information systems, and our national border. Technologies called biometrics can automate the identification of people by one or more of their distinct physical or behavioral characteristics. The term biometrics covers a wide range of technologies that can be used to verify identity by measuring and analyzing human characteristics--relying on attributes of the individual instead of things the individual may have or know. Since the September 11, 2001, terrorist attacks, laws have been passed that require a more extensive use of biometric technologies in the federal government. In 2002, GAO conducted a technology assessment on the use of biometrics for border security. GAO was asked to testify about the issues that it raised in the report, the current state of the technology, and the application of biometrics to aviation security."
