DISABILITY DATA FOR DISABILITY POLICY: AVAILABILITY, ACCESS AND ANALYSIS

Revised August 1995

I. INTRODUCTION

This paper provides background information for a meeting on data sets containing information on health care and long-term supports for persons with disabilities. The primary purpose of the meeting was to inform the research agenda of the Office of Disability, Aging, and Long-Term Care (DALTCP). The meeting was hosted by DALTCP in the Office of the Assistant Secretary for Planning and Evaluation (ASPE) in Washington D.C. on March 31,1995.

We asked participants to assist us to:

  1. Assess disability-related national data sets pertaining to health and long-term supports, particularly as related to the policy issues discussed below.

  2. Identify useful State, area, private and international data bases, including data from large federally-assisted demonstrations of managed care, integrated health services, long-term care and welfare reform.

  3. Identify next steps in analyzing available disability data.

  4. Propose priorities for DALTCP's research agenda regarding disability data.

Overview of Paper

The paper begins with two general sections: Conceptual and Policy Framework and General Orientation to Disability Data, the latter of which contains an overview of the Disability Survey (1994-1995 Supplements to the National Health Interview Survey).

There follow sections which discuss policy and research questions ASPE/DALTCP is addressing and a critique of available data on four populations of persons with disabilities: working age adults; persons under age 18; older adults; and special populations.

The concluding section poses key questions in considering a disability data strategy and identifies possible next steps in developing a disability data strategy.

An Appendix provides one-page summaries of numerous national disability data bases.

II. CONCEPTUAL AND POLICY FRAMEWORK

A. Definition of Disability

There are many ways to define "disability". The definition should be broad enough to cover all persons of interest, yet detailed enough that policy makers and program administrators can identify the target groups they try to serve.

For this paper, we consider a disability to be a limitation of activity due to chronic conditions. Such a definition, which is used by the National Center for Health Statistics (NCHS), is "slanted" toward a health perspective. This is in keeping with the Department's mission, which--with the departure of the Social Security Administration (SSA)--is likely to place greater emphasis on health and long-term care policy as they affect persons with disabilities.

In the World Health Organization's (WHO) manual International Classification of Impairments, Disabilities and Handicaps (ICIDH) (1980), impairments represent disturbances at the organ level; disabilities reflect the consequences of impairment in terms of functional performance and activity by the individual; and handicaps are concerned with the disadvantages experienced by the individual as a result of impairments and disabilities. WHO is currently producing a revision and updating of this classification.

The starting point for this paper should not obscure the difficulty of reaching a broad consensus on one or more definitions of disability or identifying all the variables required to view disability from a variety of policy and program perspectives. In the process of developing a disability data strategy, the full range of conceptual, methodological and definitional issues around disability must be examined thoroughly.

B. Basic Demographics

According to the 1990 Survey of Income and Program Participation (SIPP), approximately 40.1 million Americans living in the community have one or more disabilities because of a physical or mental health condition. There are, in addition, about 2.6 million persons with disabilities who reside in institutions. This population is characterized in the first instance by its diversity. It includes the frail elderly, persons with mental retardation or other developmental disabilities (MR/DD), adults with physical disabilities or mental illness, children with disabilities and veterans. While the specific needs of these groups vary, they share common concerns and aspirations.

C. Policy Context for ASPE's Interest in Disability Data

ASPE provides data and analyses to inform policies of the Department of Health and Human Services (DHHS). Within ASPE, DALTCP has a mandate from the Assistant Secretary to expand its research agenda on persons with disabilities of all ages, focusing on health services and long-term supports. We are conducting and planning a number of disability-related research projects.

In addition, we have responsibilities regarding policy-relevant national survey data, including adding specific questions or entire sections to ongoing surveys (e.g., National Long-Term Care Survey), reviewing surveys sponsored by agencies in the Department, and developing new surveys in cross-cutting areas such as the 1994-95 Disability Supplement to the National Health Interview Survey (NHIS).

Given the cross-cutting nature of disability issues, we are coordinating our work with other departments and agencies, including the Department of Education and the new independent SSA as well as with operating agencies in DHHS and within ASPE itself.

National programs affecting persons with disabilities have developed considerably over the past quarter century. Currently many of these programs are undergoing scrutiny within the Administration and in Congress. Policy-relevant data are needed in a number of areas. Major disability-related initiatives which would benefit from more current data and data analyses include the following:

  1. President's Disability Policy Review

    The White House has undertaken a broad review of Federal disability policy through a group chaired by Carol Rasco and Alice Rivlin. This group will review the direction of Federal disability policy and provide guidance for the next steps. Specific Work Groups include: Guiding Principles, Accommodations, Children's Issues, Employment of Working Age Adults, and School-to-Work Transition. Judy Feder and Robyn Stone of ASPE are convening the group on Children's Issues.

  2. Children with Disabilities on SSI

    Rapid growth in the number of children who are receiving Supplemental Security Income (SSI) because of a disability has generated concern and criticism at present. In consequence, a National Commission on Childhood Disability has been mandated by the 103rd Congress. See below.

  3. Health Care Reform Initiatives

    Access to health insurance is a major concern for persons with disabilities. States and private insurers are undertaking reform initiatives despite lack of a major Federal health reform initiative. Proposals for universal coverage and a ban on exemptions from coverage due to preexisting conditions offered great promise to persons with disabilities. However, this constituency has concerns about the consequences of managed care and various cost containment measures.

    In ASPE's studies of the effect of managed care options on persons with disabilities--both children and adults--valid and reliable data have not been readily available.

  4. Potential Changes in Medicare and Medicaid

    Many States are using managed care plans to serve their Medicaid beneficiaries. While people with disabilities have for the most part been carved out of these initiatives, a number of States are beginning to enroll their SSI (aged and disabled) populations in managed care plans.

    There is serious consideration of placing a cap on Federal Medicaid expenditures or turning the Medicaid program into a block grant. The Health Care Financing Administration (HCFA) expects a doubling of nonelderly disabled Medicare beneficiaries between 1980 and 2000. ASPE/DALTCP in conjunction with HCFA is examining changes in the Medicare home health benefit. In general, we need data to project consequences of different scenarios of changes in these major programs for persons with disabilities.

  5. Long-Term Support Reform

    Debate continues concerning the feasibility of a Federal program to provide block grants to States for home and community-based services, including personal assistance services (PAS), for persons with disabilities. Of particular interest are issues around consumer-directed services. Perhaps a more probable initiative is enactment of tax incentives for private long-term care insurance. Data are needed regarding who buys such insurance.

    Also of interest regarding home and community-based services are criteria for assessing State service-delivery "infrastructures" and needs for technical assistance.

    In addition, State Governments and the private sector are developing assisted living and other housing-with-services options. This gives added importance to information on the living arrangements of persons with disabilities, along with their preferences. Such information is needed on the disabled population as a whole and various subpopulations of persons with disabilities.

  6. Welfare Reform Initiatives

    Approximately one-third of women receiving Aid to Families with Dependent Children (AFDC) either have a disability, have a child with a disability or may reside with another adult with a disability (Adler, 1993). Furthermore, research reviewed by the Urban Institute (Acs and Loprest, 1994) gives some indication that women with disabilities (especially those with multiple disabilities) are less likely to exit from AFDC for paid employment within a year.

    It is unclear the extent to which job training, if enacted as a part of welfare reform, will address the special needs of persons with disabilities. DALTCP has in progress an exploratory study of impacts on persons with disabilities of welfare reform initiatives in a small sample of States.

  7. Assessment of the Americans with Disabilities Act

    As reported in Federal Implementation of the Americans with Disabilities Act (ADA), 1991-94 (West, 1994), the potential of the ADA for defending the civil rights of persons with disabilities has only partially been realized. ASPE/DALTCP is particularly interested in access to health and housing facilities.

    Our experience is that one cannot assume easy access to health institutions, even though many hospitals and clinics receive Federal support and therefore have been required by the Federal Rehabilitation Act to provide access. Accommodation of persons with disabilities in existing privately-owned rental housing is not directly addressed by the ADA. Documenting the impact of the ADA has special policy significance in today's political climate.

  8. The Changing Federal Role: (A) Devolution; (B) Reinvention

    A major theme of the current Congress is transferring responsibility for social programs to the States, generally by means of block grants. In the past there has been minimal Federal monitoring of who receives which benefits, and even less information about program impacts. For example, there are few data on which age groups receive services under the Social Services Block Grant.

    Although an increased Federal awareness of disability is suggested by the ADA and the President's Disability Policy Review, implementation of block grants potentially for nutrition, welfare, and Medicaid programs may substantially deter any Federal effort to track impacts on persons with disabilities unless provisions for so doing are explicitly incorporated.

    The Reinventing Government effort--that is making government "leaner"--has implications for disability data. In an era of diminishing resources, there is consideration of how to consolidate surveys, establish standards for data collection and better organize data collection responsibilities within agencies. Undertaking new data collection initiatives in this environment will require considerable justification.

III. GENERAL ORIENTATION TO DISABILITY DATA

A. Federal Data Bases

The United States has a wide variety of data bases on persons with disabilities--national, State and private. The collection of data on persons with disabilities has made considerable progress over the past decade.

In the near future, data sets will become available that will shed light on the characteristics, service use, expenditures and sources of payment for many groups of persons with disabilities. Most notable is the Disability Survey, which is being administered as a supplement to the NHIS in 1994 and 1995. This survey will serve as the "work horse" of disability analyses for the foreseeable future.

Even with such promising developments, a number of data problems persist. The Department's experience in examining health and long-term care reform options highlighted some of these problems.

  • While much is known about the frail elderly and their use of services, relatively little is known about other groups of persons with disabilities such as children, working age adults and special populations (e.g., mentally ill, developmentally disabled) that cut across age groups.

  • Though not ideal, the activities of daily living (ADLs) provide reasonable measures of functioning for older persons with physical disabilities; however, we lack equivalent measures for persons with cognitive impairments or mental illness and for children regardless of their type of disability. Self-reported ADL status is inherently a "soft" measure of disability and one subject to a lot of variability in the short run.

  • More consistent policies on measures and data systems on persons with disabilities are needed. At the national level, the data systems are largely decentralized and there remain significant gaps in coverage. Improved coordination, planning and priority setting among Federal agencies are required to make possible the best analytic uses of the data bases.

  • There should be development of longitudinal data bases (including panel studies) on the general population with disabilities and special subpopulations.

  • Increased access is needed to subnational data bases, including State and local surveys, data from federally funded demonstration programs, and proprietary data systems.

  • There should be more frequent and routine linkage of survey data with administrative records such as Medicare, Medicaid, and Social Security.

Other specific recommendations for improving disability data collection include:

  • Routine inclusion of disability measures in ongoing national data collection systems (LaPlante in National Council on Disability, 1992, p.35).

  • In Federal statistical reports, tabulation of findings by disability along with other standard demographic variables (e.g., age, race and income) (LaPlante, ibid.).

  • Increased focus on gaining congressional support for expanded data gathering on disability (LaPlante, ibid.).

  • Reporting information in the Current Population Survey (CPS) on labor force participation by persons with disabilities every month rather than only in March as is now the practice of the Bureau of Labor Statistics (Yelin, 1992, p.157).

B. Overview of the 1994/95 Disability Survey (Supplement to NHIS)

The 1994/95 Disability Survey, the most comprehensive national survey on disability ever undertaken in this country, will provide information on research and policy issues related to disability. It is the first exhaustive survey of disability since 1978 and the first ever to collect national population-based data on children with disabilities and persons with developmental disabilities.

Data from the 1994/95 Disability Survey will enable us to understand more about people with disabilities--their numbers, characteristics (e.g., demographic, socio-economic, health, participation in Federal programs), service use and expenditures, and aspects of their daily lives (housing, transportation, employment, personal assistance). Data from the survey are relevant to the following policy questions:

  • What are the characteristics of people with disabilities who rely on DHHS programs?

  • Why is growth in SSI and Social Security Disability Insurance (SSDI) enrollment (and the companion Medicaid and Medicare programs) and costs so high?

  • Why is employment among persons with disabilities so low and why do some people with the same disabilities work while others do not?

  • What is the extent of disability among children and why is SSI growth so high, what role do recent changes in SSI eligibility (i.e., Zebley Supreme Court decision, new childhood regulations, expanded mental impairment criteria) play?

  • How do persons with MR/DD access community services and what is the role of Medicaid?

  • How do access to health care, health care utilization, and public versus private health insurance coverage vary for people with disabilities?

  • What is the impact of racial/ethnic differences in disability?

The 1994/95 Disability Survey grew out of a coordinated interagency and inter-Departmental effort at DHHS to obtain timely and complete disability data.

Under an ASPE contract, Mathematica Policy Research, Inc. produced a design for a national survey of persons with MR/DD as well as detailed measures and data collection instruments. A supplement to the NHIS was proposed as the vehicle for the MR/DD survey. This work served as the foundation for a more comprehensive Disability Survey.

The questionnaire was extensively reviewed by the Federal disability community, advocacy groups, and academics. In addition, the questionnaire was voluntarily tested by people with disabilities and their families at the NCHS Cognitive Questionnaire Lab. Finally, a pretest involving 250 households was also conducted in the Washington, DC area.

The 1994/95 Disability Survey is actually a two-year supplement to the National Health Interview Survey (NHIS). The NHIS has been collecting information on the nation's health since 1957. Samples are huge. About 100,000 households representing 240,000 people in the civilian non-institutionalized population will be interviewed.

The 1994/95 Disability Survey has two parts or phases, each of which consist of personal interviews in respondents' homes. Phase I is administered to the 240,000 respondents selected in the NHIS sample. Phase I interviews began in January 1994 and will continue through December 1995. Phase I contains many in-depth disability measures, as well as information on severity, onset, duration, and disabling condition.

Phase I disability measures include standard limitation of activity measures and detailed measures of sensory impairments, functioning of specific body systems, six separate ADLs, six separate instrumental activities of daily living (IADLs), mental illness, assistive devices, childhood disability, and functioning for children under five. People with MR/DD (using the legislative definition) can also be identified.

Many disability measures are standard, while others--notably those on children, mental illness, and developmental disabilities--are new and were derived with this survey in mind. Besides information on disability, data on health care, demographic, socioeconomic, health insurance, and program characteristics of people with and without disabilities are also gathered in Phase I.

Phase II is administered about 6-9 months after Phase I to about 40,000 respondents with serious disabilities. Phase II began in the Fall 1994 and will end in Fall 1996. Phase II collects data on service use and expenditures, housing, long-term care services, home care, personal assistance, respite care, transportation, employment, accommodations, work history, vocational rehabilitation, relationships, family structure, family impact (for children) and child care (for children).

Information from the Disability Survey can be linked to administrative disability records at SSA and Medicare records at HCFA. Furthermore, while the Disability Survey is a one-time or snapshot survey, provisions can be made to follow respondents back and re-interview them for longitudinal studies. Final results could be released in early 1997 and preliminary results by early 1996.

IV. DATA ON WORKING AGE ADULTS

A. Key ASPE/DALTCP Policy Concerns

In developing the long-term care proposal in the Health Security Act and defining a benefits package, analysts in ASPE and elsewhere lacked data about working age persons with disabilities and their use of services. We relied primarily on data from the National Long-Term Care Survey (NLTCS) and the model of service use and costs developed by Brookings and Lewin-VHI for projections of target populations and costs for persons aged 65 and over.

In general, we have limited data on working age persons with disabilities in regard to key DHHS policy concerns. These include:

  • Use and costs of PAS and related supports. Recent expert meetings confirmed our need for data on uses and costs of PAS and related supports (such as assistive technology or adaptations) and for certain basic health benefits such as maintenance rehabilitation.

  • Impacts of increased reliance on managed care on persons with disabilities. Managed care is a centerpiece of most reform initiatives being implemented by many States (e.g., for their Medicaid programs) and by private insurers. While managed care holds promise of providing, under one auspice, an array of needed services by persons with disabilities, persons with disabilities and their advocates express a number of fears and concerns about potential disadvantages of managed care. These center on access to and receipt of appropriate services.

    There are few data to address key questions such as functional and demographic characteristics of persons with disabilities in managed care and the impact of managed care on access to needed services, affordability and costs, and on individual outcomes.

  • Incentives or barriers to employment of persons with disabilities. Incentives and barriers to work for persons with disabilities include access to health insurance and to long-term supports. ASPE/DALTCP has in progress research to determine what data are available on the use of PAS and of assistive technology by workers with disabilities to answer questions such as:

    • What number and proportion of workers use PAS, assistive technology, and adaptations and to what extent are these used in the work place?
    • To what extent do employers provide for personal assistance in the work place or pay for assistive technology and other adaptations?

  • How persons with disabilities or parents of children with disabilities would be affected by proposed changes in the AFDC program. As mentioned above, ASPE/DALTCP is sponsoring exploratory telephone interviews with officials in five States which have undertaken welfare reform initiatives. In addition, ASPE is sponsoring an evaluation of State welfare reform initiatives. It is anticipated that data collection will include questions concerning AFDC recipients who have disabilities or who have children with disabilities.

B. Existing Data Sources

Numerous Federal surveys collect disability data on the working age population (aged 18-64), but except for the 1994/95 Disability Survey, none focus primarily on disability. That was not always the case. SSA conducted the Surveys of Disability and Work every few years beginning in the early 1960s in order to measure the extent of disability in the working age population and to examine the experience of disabled workers on SSDI and their families. The last Survey of Disability and Work was conducted in 1978 and there are no plans to repeat the survey.

Nowadays, data sources include either special surveys on disability (like the 1994/95 Disability Survey) or the addition of disability questions on non-disability surveys. Besides the 1994/95 Disability Survey, the major sources of information on the entire working age population with disabilities include:

  • 1990 Decennial Census,
  • 1984, 1990-96 Surveys of Income and Program Participation (SIPP),
  • 1957-95 National Health Interview Surveys (NHIS),
  • 1987 National Medical Expenditure Survey (NMES), and
  • Annual Current Population Surveys (CPS).
  • In addition, the Medicare Current Beneficiary Survey (MCBS) covers SSDI beneficiaries eligible for Medicare--a small but policy-relevant segment of the working age population with disabilities.

    C. Strengths and Weaknesses

    The sheer size of the working age population with disabilities is immense. Although disability rates are much lower among the working age population (13.7 percent) than among the elderly (54.8 percent), more people with disabilities are in their working years (21.1 million) than in their elderly years (17.1 million).

    The working age population is not only large, but heterogeneous, and is in fact made up of many smaller groups, most of whom are too small to pick up in surveys. These small often policy relevant groups can be based on condition (i.e., mental retardation, mental illness, multiple sclerosis, spinal cord injury), type of impairment (i.e., mental, physical), program participation (i.e., SSDI, SSI, VA), onset (congenital, childhood, early or late adulthood), age, gender, and race. Only the 1994/95 Disability Survey with its huge samples can hope to gather data on many of these small groups.

    There are crucial but unresolved definitional and measurement issues among the working age population. No equivalent severity measures and survey questions have been developed for physical versus mental impairments. The standard functioning questions based on ADLs and IADLs often break down. Since mental illness and mental retardation are major disabling conditions in this age group, this is a critical gap.

    The relationship between functional disability and work is also not well understood. Some people with the same level and type of disability work while others do not. Besides disability, a host of other factors are important in the decision to begin or return to work. These can include occupation (i.e., sedentary, manual labor), educational attainment, and age (those in their 60s may wish to stop work and retire early).

    A small but important segment of the working age population with disabilities are institutionalized (i.e., nursing homes, mental hospitals, prisons) or are homeless. Since few national surveys include this population and since the few surveys which focus on the institutionalized (i.e., the National Nursing Home Survey) have very small samples of the nonelderly, we know little about this group.

    Most Federal disability programs focus on the nonelderly and many of these pertain to people in their working years. These programs have administrative records which, if linked to national population-based surveys, could strengthen and expand our knowledge. However, administrative data is often not linked for reasons of confidentiality or simply because no such considerations were made.

    V. DATA ON PERSONS UNDER AGE 18

    A. Key ASPE/DALTCP Policy Concerns

    A major policy focus for this age group concerns issues relating to benefits for children under the Federal SSI program. In 1994, almost three times as many children received SSI benefits (approximately 900,000 children) as did in 1989. This dramatic growth in the SSI program and the changing characteristics of the children who participate--most notably a presumed increase in children with mental impairments--has caused scrutiny of the program by the Administration and the Congress.

    By Congressional mandate, the National Commission on Childhood Disability is reviewing the SSI program and the needs of children with disabilities. ASPE/DALTCP has been involved in developing a research agenda for the Commission. In addition, ASPE and DALTCP staff are leading the task force on disability programs for children as part of the Administration's Disability Policy Review.

    The Commission has authority to examine:

    • causes of program growth;
    • eligibility criteria and determination;
    • relative merits of voucher rather than cash benefits;
    • effects of SSI benefits on children and their families; and
    • merits of alternative approaches to helping children achieve future independence and employment, including closer involvement of private organizations in providing services.

    In addition the Commission's charge includes consideration of Federal health assistance programs for children and the interactions of SSI with other public medical, special education, and case management programs.

    Our plans to date for generating information for the National Childhood Disability Commission include analysis of early data from the Disability Survey; a synthesis of SIPP, Census, and NHIS data, and studies of use of Medicaid-funded services by SSI recipients.

    In addition to its work with the Commission and the Disability Policy Review, ASPE/DALTCP and other ASPE programs are undertaking a program of research on children with disabilities. Projects include analyzing use of Medicaid services by children with disabilities, examining managed care programs for children with disabilities, and describing the extent to which school systems meet requirements for provision of related services under the individuals with Disabilities Education Act by using Medicaid benefits.

    More broadly, the "reinvention" of the Federal Government and the shift toward consolidating categorical programs, establishing block grants and capping expenditures for major programs (e.g., Medicaid) could have significant impacts on children with disabilities.

    We recently awarded seven research grants for projects which make use of available data sets. These include State and local data bases. Topics include assessment of policy implications of alternative functional definitions, patterns of service use and costs within several States, interactions of the AFDC and SSI programs with regard to children with disabilities.

    B. Existing Data Sources

    Little information exists on children with disabilities. The major sources of information are:

  • 1994/95 Disability Survey,
  • 1984-96 Surveys of Income and Program Participation (SIPP),
  • 1957-95 National Health Interview Surveys (NHIS),
  • 1987-88 Survey of Families and Households, and
  • 1987 National Medical Expenditure Survey (NMES).
  • Program records from SSI and the special education programs also contain disability data.

    C. Strengths and Weaknesses

    It is difficult to measure disability in children-much more so than for adults. Furthermore, the younger the child, the harder it is to understand, articulate, and measure disability. In fact, disability is a very different concept for infants, toddlers, preschool children, school-age children, and adolescents. Whereas play is the usual activity for children aged 3-5 and attending school for those aged 5-17, the usual activity of infants and toddlers (growing, developing?) is unclear and hard to measure. The lack of standard measures meant that new questions needed to be created for the 1994/95 Disability Survey.

    Although children constitute about a quarter of the population, national surveys often include few children with disabilities in their samples. This is because the prevalence of children with disabilities is small (about 6 or 7 percent of all children) and because major surveys like the SIPP and the CPS are really focused almost exclusively on adults (people aged 15+ or 16+).

    For example, SIPP has collected data on children's disability since its inception, but none on children's SSI participation, because SSI receipt is in the core set of questions designed solely for adults. (This will be remedied starting with the 1996 SIPP.)

    While longitudinal data are universally scarce for people with disabilities, their lack is especially crucial for children, who change much more rapidly than adults in regards to disability and everything else. Finally, children live in families. While data on a child's disability is crucial, we also need to know about his or her family and their characteristics in order to gain an accurate understanding of the issues.

    VI. DATA ON OLDER ADULTS

    A. Key Policy Concerns

    While data on older adults with disabilities is more extensive than for other populations, there are significant gaps.

    • Modeling Service Use and Costs. Increases in the aging population, especially in numbers of persons over age 80 or 85 who are at greatest risk for needing health and long-term care services, dominates much debate over policies on older adults. A major emphasis of ASPE/DALTCP's recent work with regard to older adults has been modeling long-term care service use and costs by persons age 65 and older using primarily data from the NLTCS.

      Use of the model greatly facilitated development and acceptance of the long-term care proposal for various health reform bills last year. We plan to extend this model to estimating acute care costs in order to project consequences for policy changes such as, for example, adding co-payments to Medicare home health benefits or increasing Medicare Part B premiums.

      We would also expect to examine the impact of integrated acute and long-term care strategies on public and private expenditures. In addition, we propose to extend our capability to understand impacts within States of changing use and costs of acute and long-term services, using Census data, the NLTCS and the Disability Survey.

      A key question is the extent to which increased life expectancy is accompanied by a longer period of disability and chronic illness. There is some evidence from earlier rounds of the NLTCS that the prevalence of disability among the elderly is decreasing. Data from the 1994 NLTCS may provide further assessment of these trends.

    • Changes in Medicare Home Health Care Benefits. Medicare home health and skilled nursing facility expenditures have quadrupled in the past five years, from $2 billion to over $8 billion. We are undertaking research in collaboration With the Health Resources and Services Administration (HRSA) and HCFA to understand the nature of these increases and the extent to which Medicare home health benefits are changing from a post-acute care step down benefit into a source of long-term custodial care for the elderly.

      We also hope to link the Medicaid Statistical Information Systems data set with the MCBS to examine the mix of skilled and custodial home care benefits by persons dually eligible for Medicare and Medicaid.

    • Subacute Care. Subacute care--i.e., comprehensive, specialized services provided in settings other than hospitals--has emerged as a policy concern for both the Medicare and Medicaid programs and to those involved in health reform. We are attempting to describe use of subacute care in both fee-for-service and managed care settings and its effects on acute (i.e., hospital) and other traditional post acute services. Expected and achieved outcomes are also at issue. At this point data for such analyses are limited, so that we are undertaking case studies of four market areas.

    • Long-Term Care Insurance. A key proposal of long-term care reform--incentives for private long-term care insurance--continues to be of interest to Congress and may be pursued separately from other health reform proposals. As noted above, data are lacking on the availability, coverage and use of such insurance. We are particularly interested in assessing the impact of State regulation on the affordability and quality of, as well as consumer satisfaction with various long-term care insurance products.

    • Housing with Services. As the long-term care system evolves, more emphasis is being placed on combining housing and PAS for the frail elderly in community settings. We are interested in examining a variety of housing with services options, including board and care homes, assisted living facilities, continuing care retirement communities and others.

      There is a need for current and comprehensive data on such places in order to determine their appropriate role in the long-term care system.

    • International Comparisons. ASPE has undertaken a project to strengthen collection, analyses and dissemination of comparable data about long-term care in Japan and the United States. This work involves collaboration with HRSA and the Leadership Center for Longevity and Society at Mount Sinai Medical Center. ASPE provides support for analyses of informal caregiving in several industrialized societies.

      Other international efforts are underway as well, including working with WHO on the revision of the ICIDH, with special attention to how it affects disability policy.

      ASPE also participates actively in the International Collaborative Effort (ICE) on Aging, sponsored by NCHS. For example, in one project on the outcomes of nursing home care in five countries, the ICE on Aging researchers have highlighted the need for improved measurement and data collection comparability among nations (Van Nostrand et al., 1993).

    B. Existing Data Sources

    The major sources of data on the frail elderly include the NLTCS (1 982, 1984 and 1989), the Longitudinal Study of Aging, the Asset and Health Dynamics of the Elderly Survey and the MCBS. The elderly are included in most general purpose surveys like NHIS and SIPP, but sample sizes for the frail elderly--especially those at advanced ages--are typically small.

    C. Strengths and Weaknesses

    For purposes of determining disability status among the elderly, surveys tend to focus on the ability of respondents to carry out ADLs and IADLs. However, operational measures of these activities vary widely across surveys. There are discrepancies regarding the sources of assistance; some measures focus on active personal assistance, others include standby or supervisory assistance and still others cover assistive devices. The lack of consistent measures has contributed to a wide range of estimates of size of the frail elderly population.

    Measures of cognitive disability have not kept pace with the measurement of physical disability. This is a major concern, in light of the policy focus on persons with Alzheimer's Disease and related dementias.

    Existing sampling frames are inadequate for accurately and efficiently identifying places where frail elderly persons reside. The growth of housing with services options means that elderly persons with disabilities can live in places other than their own home or a nursing home. These alternative living arrangements include board and care homes, assisted living facilities, continuing care retirement communities and other related group living arrangements.

    The Census Bureau classifies places as households or group quarters, the latter being subdivided into institutional and non-institutional group quarters. Unfortunately, this classification means that assisted living facilities and similar arrangements can show up in any or all of these categories. This makes screening and sampling extremely expensive and inefficient.

    Other problems include small sample sizes for persons aged 85 or over, inadequate coverage of minority elderly, insufficient geographic detail, obstacles to administrative record linkages, and paucity of longitudinal data for measuring transitions in old age. Most critically, we lack an appropriate conceptual framework with corresponding measures to study disability across the lifespan.

    VII. DATA ON SPECIAL POPULATIONS

    A. Key ASPE/DALTCP Policy and Research Concerns

    In general, it is important to note that proposed cutbacks in the SSI program, State and private health reform initiatives, and potential changes in Medicare and Medicaid are all policy issues which affect special populations of persons with disabilities. In addition, racial, ethnic, and gender differences in service needs and use are increasingly important variables in designing programs, given the increasing heterogeneity of the U.S. population and increased incidence of disability among minority populations.

    An issue regarding special populations which is of particular concern to ASPE/DALTCP is how well persons with serious mental illness or mental retardation are served by a "generic" system of home and community-based services. For example, ASPE/DALTCP is proposing to convene a meeting to address the long-term care needs of persons with developmental disabilities involving mental retardation and whether they are best served by separation from or integration with other long-term care programs.

    One interesting concept involves identifying tracer "conditions", whereby persons with particular disabilities--especially the more rare populations--could be tracked in terms' of service use, expenditures and payment sources.

    Eligibility determination for a system serving multiple populations is a particular issue. For example, persons with serious mental illness are concerned not only about selfcare functions but also with functioning in social and recreational settings as well as at work. This population is also concerned that bureaucratic gatekeeping based on ADL impairments would not offer eligibility to needed services for them.

    Further, persons with mental illness often have periods of relative good health and functioning but argue that continued access to long-term supports during these times would be cost-effective in that health would be sustained over longer periods with supervision and other supports. The MR/DD population tends to need supervision or cuing to perform ADLs, as well as help with IADLs. Hence eligibility based on need for hands on help with self care activities is inappropriate.

    A focus of the President's Disability Policy Review is the transition of young adults from school to work. Various policies and programs have an impact on readiness to work of a young adult with disabilities including not only special education interventions and the availability of suitable employment but also access to health insurance and needed personal assistance and assistive devices.

    Other special populations, e.g., persons with mental illness or developmental disabilities, are also concerned with linkages between long-term supports and social, recreational, and work settings.

    B. Existing Data Sources

    In light of a variety of policy and program concerns, data needs on special populations can be grouped into four categories: (a) prevalence data for the population as a whole and major subgroups; (b) data on socioeconomic status, health status, functioning and related demographic characteristics; (c) data on service use, service needs, service costs; and, (d) data on developments over time for special populations as they move from childhood to adulthood to old age.

    Special populations with certain disabilities (e.g., MR/DD) are rare in the population as a whole, though they are significant from a policy perspective. Existing surveys often fail to include measures for identifying them. There are three nationally representative surveys with some information about special populations: SIPP, NHIS and NMES.

    For some special populations, e.g., persons with developmental disabilities, there also exist State surveys and narrowly focused studies, covering participation in selected programs or particular living arrangements (such as large residential facilities). All are able to shed some light on special populations.

    C. Strengths and Weaknesses

    The principal limitations across the three national surveys include:

    • Inadequate flexibility in the data to distinguish between mild and moderate disability from severe disability.

    • Focus on Federal program participation rather than comprehensive coverage of individuals' service needs.

    • Insufficient coverage of nonmedical family and community-based services, such as day care, supported employment, crisis intervention, assisted living and case management.

    • Small or non-representative sample sizes.

    In addition, NHIS and SIPP are limited to the non-institutional population, with SIPP beginning with respondents age 15 and over. NMES included persons in facilities, but tended to exclude those in small community-based residential settings.

    More narrow surveys and studies provide a rich source of information about special populations. However, without a clear idea of the representativeness of the persons included in these studies, it is not possible to put the findings in context.

    The Disability Survey, which is being administered as a supplement to the NHIS over a two year period, will go a long way toward remedying many of these concerns (though, as noted, it is household-based and excludes institutions).

    VIII. A DISABILITY DATA STRATEGY

    A. Key Questions

    In developing a disability data strategy that meets ASPE's specific policy research agenda and at the same time serves the interests of the research community more broadly, a number of questions suggest themselves.

    1. Content

      • What are the relative priorities on collecting data at the level of:

        • persons?
        • families and households?
        • providers?
        • environment?
        • specific programs?

      • Is there a need for a "minimum data set" of disability-related data elements that are routinely collected?

    2. Coverage

      • Since many major national surveys cover only the civilian noninstitutionalized population, how can coverage be extended to persons in institutions, persons in the armed forces and persons living abroad as part of an overall disability data strategy?

      • Should a higher priority be given in the future to separate disability surveys or inclusion of standard disability measures in existing surveys?

      • What would be needed to assure that standard disability measures are included in existing or planned surveys?

    3. Sampling

      • How can existing sampling frames, which are built around housing units and group quarters (institutional and non-institutional), be changed to identify more easily persons with disabilities who live in alternative housing arrangements (assisted living facilities, board and care homes, independent living facilities, etc.)?

      • What are the key policy-relevant subgroups of persons with disabilities, for which sufficient sample sizes are needed for accurate estimation along critical dimensions?

      • What strategies are needed to assure representativeness of key disability-related subgroups in sample surveys?

    4. Periodicity

      • What can be done to collect data on persons with disabilities on a more regular and predictable basis?

      • Given budgetary realities, should the emphasis be on one time or occasional surveys that collect a lot of data or more regular and frequent surveys that collect fewer data?

      • In light of budgetary realties, what relative priority should be given to: (a) longitudinal surveys, (b) panel surveys, and (c) cross-sectional surveys?

    5. Access

      What can be done to assure the timely production of useful and widely available public use tapes?

    6. Administrative Records

      What can be done to improve access to administrative records and link them to national survey data?

    7. Subnational and International Estimation

      • To what extent should Federal resources be expended to generate estimates at the State and sub-State level on the prevalence, incidence and types of disability?

      • What role should the Federal Government, DHHS and ASPE play in promoting State and subState data collection on disability?

      • What role should the Federal Government, DHHS and ASPE play in fostering expansion and comparability in international data collection and coding (i.e., ICIDH) on disability?

    8. Modeling

      How can microsimulation models on financing and personal assistance services for persons with disabilities be developed and what would be the critical features of such models?

    B. Potential Next Steps

    The following is a list of potential next steps for ASPE that could help articulate and support a policy relevant disability-related data strategy.

    • Exploration of accessing data from demonstrations and waiver programs (e.g., 1115 waivers) for analysis, with emphasis on the methodological and cost implications of this approach for related data collection.

    • Provision of technical assistance to States in their disability-related data collection efforts.

    • Support for expanded analyses of existing disability-related data by researches and policy analysts.

    • Encouragement of linkages of administrative records to survey data.

    • Promotion of the use of disability measures; in general, purpose surveys to help monitor the impact of new policies and programs (e.g., block grants) on persons with disabilities.

    • Hosting of a disability data conference, resulting in proceedings, special issue of a journal and/or a book.

    • Establishment of a Federal interagency coordinating body on disability statistics (analogous to the Federal Interagency Forum on Aging Related Statistics).

    Comments
  • functioning questions indicate severity of impairment by asking if the person gets help, if someone stands by, or if special equipment is used
  • data are linked to Medicare administrative files, providing information on services used
  • because it has three rounds per year, facilitates analysis of changes in the beneficiaries and their use of services; follows individuals through different care settings
  • surveys those who have Medicare coverage: (a) not nationally representative of individuals under age 65 who have a disability or of the potentially disabled population, but (b) is representative of the population age 65 and over
  • no disability indicators for cognitive impairment, severe mental illness, or general emotional problems
  • longitudinal design permits observation of individual changes over time

    Frequency 1971-1975 (NHANES I), 1976-1980 (NHANES II), 1988-1994 (NHANES III); a special study of the Hispanic population was conducted in 1982-1984.
    Purpose To assess the health status of the US population; to estimate the national prevalence and investigate trends in selected disease and risk factors; and to monitor trends in prevalence, awareness, treatment, and control of diseases.
    Design Respondents are interviewed at home, then examined, tested and interviewed again in a mobile examination center. NHANES III offered a home examination option for those unable or unwilling to come to mobile examination center.
    Content Data on health insurance; income and income assistance; family housing characteristics; physical and cognitive functional impairments; selected disabilities/conditions; and health and nutrition status.
    Disability Measures Measures in NHANES III include functional limitations (cognitive, physical and social), as well as the presence of selected health conditions. Questions asked of persons 17+ (60+ from 1988-91) regarding physical functioning, i.e., difficulty in performing certain physical activities, and need for assistance with ADLs and IADLs. Includes questions on use of assistive devices. Respondent are asked about receipt of Social Security benefits due to disability.
    Coverage Civilian, non-institutionalized population aged two months and older. (NHANES I covered persons aged 1-74 years; NHANES II covered persons 6 months to 74 years).

    Comments
  • use of direct testing rather than self-reporting
  • records can be matched with the National Death Index and HCFA Medicare claims data
  • useful for the study of the contribution of multiple diseases to disability in old age (NHANES III)
  • ADL and IADL questions were asked only of the 60+ population from 1988 to 1991
  • long intervals and variations in wording between surveys make comparisons in certain areas problematic

    Purpose To provide nationally representative data on the health status, health related behavior, and use of health services by the U.S. population.
    Design Core questionnaire on health and disability status. Periodic supplements on selected topics; e.g., 1994 and 1995 Disability Survey. Face-to-Face home interviews with trained Census personnel.
    Content Demographics, health and disability status, acute and chronic conditions, use of doctors and hospitals, income, health insurance, and program participation.
    Disability Measures The core questionnaire measures limitations at four levels: unable to perform major activity, limited in major activity, limited in nonmajor activity, and not limited in activity. Looks at prevalence of chronic conditions or impairments and restricted activity days.
    Coverage Civilian non-institutionalized population.
    Sample 50,000 households (125,000 persons) annually; in 1995 will include approximately 40,000 households and 100,000 persons.
    Products Publications (e.g., Advance Data Reports), public use data tapes, CD-Rom.
    Future Major redesign of questionnaire for 1996 is underway.
    Comments
  • repeated cross-sectional, with capability for providing longitudinal information; can establish trends in prevalence of disability
  • using core, cannot estimate how many ADL or IADL limitations a person has
  • core interview does not have information on cognitive impairment; does include information about chronic and mental conditions; new design will include measures of depression
  • only asked IADL questions in certain circumstances
  • no measures of assistive devices within core, however, this subject was covered in 1990 supplement
  • for those age 65 and above, core asks if need help with ADLs and IADLs, but not for each ADL and IADL individually; also asked of persons under age 65 who report limitations
  • While there are some gaps with disability measures in the core interview, many of these issues are addressed in the various supplements, such as those described below. For the special questionnaires, one adult is subsampled from the family; self-response is required. (In some supplements, questions are asked of everyone in household, and proxy responses are allowed.)
    1988 Child Health Supplement
    Disability Measures Various medical conditions, including missing limbs or permanent impairment, stiffness, or deformity of any limbs; asks questions about development, learning disabilities, and emotional or behavior problems lasting three months or more.

    1989 Mental Health Supplement
    Disability Measures Diagnosis of major mental illness, ADLs, IADLs, social functioning, disability payment due to mental illness.
    Comments
  • duration and severity of problems in functioning

  • 1990 Supplement on Assistive Devices
    Disability Measures Sets of questions about specific devices for mobility, hearing, vision, and speech; special features in the home designed for disabled persons.
    Comments
  • may slightly overestimate those with chronic illnesses or impairments who use devices such as wheelchairs, etc. which may be used due to acute conditions
  • gives estimates of unmet need
  • 1991 Supplements
    Disability Measures Hearing; difficulty in or help with ADL and IADL related measures; chronic and disabling conditions; mental health.
    Comments mental health questions do no relate to a specific diagnosis of illness; do not know what the reason is for certain emotions
    1994 Access to Care Survey
    Disability Measures Focuses on unmet needs, particularly on the acute care side; asks what kinds of services were needed.
    Comments
  • useful when used along side the core interview to gain a better picture of disability
  • service need does not necessarily indicate severe disability

    Comments
  • not designed as a disability survey, but can look at the household as a unit rather than and individual person, thereby getting some idea of the level of disability and burden households are facing
  • addresses the duration of disability by referring to care in past twelve months; also refers to continuing burden by asking if person is still receiving care

    Frequency 1984, 1994
    Purpose SOA, a supplement to the 1964 National Health Interview Survey, establishes baseline data (for LSOA) to study changes in functional status among the elderly, and the relationship between social and health factors and death. SOA II is intended to serve as a comparison cohort to the 1964 SOA cohort, and possibly as a baseline for a second Longitudinal Study on Aging (LSOA II). SOA II replicates SOA I to see if there are changes in the disability process, to study the healthy aging, to focus on unmet need, and to examine problems in elderly women.
    Design Cross-sectional national survey collected through household interviews.

    SUMMARY OF ASPE MEETING ON DISABILITY DATA

    August 1995

    I. INTRODUCTION

    The Office of the Assistant Secretary for Planning and Evaluation (ASPE) sponsored a meeting of experts on the topic of Disability Data for Disability Policy. The meeting focused on data relevant to health and long-term support. It was hosted by ASPE's Office of Disability, Aging and Long-Term Care Policy (DALTCP) at the Holiday Inn Capital in Washington, D.C. on March 31, 1995.

    This day-long meeting was the last of three expert meetings on disability topics, in which DALTCP sought advice for its newly-expanded research agenda on disability. National experts in disability data sets relating to children, working age adults, the elderly, and special populations joined with representatives of Federal agencies to examine the availability of, access to and potential analyses of disability data.

    The specific objectives of the meeting were to:

    • Assess disability-related national data sets pertaining to health and long-term supports, particularly as related to the policy issues discussed in the background paper Disability Data for Disability Policy: Availability, Access and Analysis, prepared by DALTCP staff and distributed to the participants prior to the meeting.

    • Identify useful State, area, private and international data bases, including data from large federally-assisted demonstrations of managed care, integrated health services, long-term care and welfare reform.

    • Identify next steps in analyzing available disability data.

    • Propose priorities for DALTCP's research agenda regarding disability data.

    II. SUMMARY OF PARTICIPANTS' COMMENTS AND RECOMMENDATIONS

    A. Environment

    In the current environment, several participants stated that new Federal funding for large national surveys relating to disability was unlikely. At the same time there is an ongoing need for data in the light of societal changes and policy issues affecting persons with disabilities.

    From the perspective of the Department of Health and Human Services (DHHS), changes in the health care system are of critical importance. Data are needed to monitor the impact on persons with disabilities of efforts to control access and reduce costs under managed care systems. Similarly many welfare reforms initiated by States will have an impact on persons with disabilities.

    The availability of personal assistance services and the role of consumer choice in service delivery is an important issue for DHHS. Other areas of concern to persons with disability are factors affecting labor force participation (e.g., vulnerability in recessions) and access to affordable housing.

    With reduced Federal funding, it will be necessary to search for and make better use of subnational and private sector data sets to explore these issues.

    B. Themes

    Among the themes highlighted by participants were the following:

    1. Longitudinal Data

      Participants stressed the need for longitudinal data on disability. National surveys like the National Health and Retirement Survey (NHRS) and its companion Assets and Health Dynamics of the Oldest Old Survey (AHEAD), the National Longitudinal Survey of Youth and the Panel Study of Income Dynamics were mentioned as sources of longitudinal data. Section D below discusses State-level data sources, which may include longitudinal data.

    2. Disability Measures

      There is a need for a wide range of disability measures on surveys, so that researchers can select particular measures appropriate for their investigations. Researchers need to report on the precise measures they are using in their analyses.

      At the same time, the creation of a minimum data set on disability should be explored; such a data set could be included in all population-based surveys.

    3. Interdisciplinary Collaboration

      The selection and development of survey domains--e.g., income and assets, health, work, functioning--should be done on an interdisciplinary basis. This was done effectively in the case of the NHRS and AHEAD surveys. (NHRS focuses on a baseline cohort aged 51-61 in 1992. AHEAD includes persons aged 70 or over in 1993.)

    4. Control Groups

      Where feasible, control groups should be included among survey respondents to compare findings on persons with disabilities to persons without disabilities.

    C. Coverage

    Participants made a number of recommendations on obtaining updated disability data. Among them were the following.

    • Include at least broad questions on disability on all major population-based surveys.

    • Expand the number of disability questions on the Current Population Survey. Include among them one or more questions on working conditions and ask the questions monthly.

    • Expand AHEAD's survey modules to capture more aspects of disability and test experimental approaches.

    • Extend NHRS to younger age groups; among other things this could permit capture of data before and after the onset of disability for some individuals.

    • Add Supplemental Security Income status to questions on children in the Consumer Expenditure Survey, the Survey of Income and Program Participation and all other major economic surveys.

    • Incorporate hypotheses and measures from epidemiological studies into the development of national surveys; for example, it is possible that clinically-derived measures of cognitive impairment could be adapted to large-scale surveys.

    • Oversample children in national surveys.

    • Consider more focused surveys rather than oversampling on large surveys; one possibility is a survey of families who have children with developmental disabilities to evaluate the impact of cash payments.

    • Track users of services (e.g., mental health services) across different service systems.

    • Make greater use of questions from national surveys, e.g., National Medical Expenditure Survey for health expenditure information, in State surveys. With appropriate weights, national surveys could thereby be used for State-level estimation.

    • For the planned redesign of the National Health Interview Survey, retain the conditions list and incorporate questions on work capacity plus cognitive, social and physical functioning.

    D. Data Sources

    Some federally-sponsored surveys have disability data that could be more fully utilized. The revised version of the background paper now provides information on such surveys as: the Behavioral Risk Factor Surveillance System sponsored by the Center for Disease Control (CDC), the National Household Survey on Drug Abuse, and the Department of Veterans Affairs' National Survey of Veterans. The National Institute on Mental Health is currently sponsoring the development of a new national survey with disability-related measures titled Use, Needs, Outcomes and Costs in Child and Adolescent Populations.

    In addition to national surveys, it will be necessary in the future to make greater use of subnational data sources, such as:

    • State surveys and information systems,
    • natural experiments,
    • school systems,
    • Workmen's Compensation files, and
    • cata from demonstrations and waiver programs with a disability focus.

    Insofar as possible, national surveys should be replicated at the State level or at least key data elements from these surveys incorporated into State surveys. State and local government monitoring systems are another potential source of useful data on persons with disabilities. The benefits to State and local governments in increasing access to their data need to be highlighted.

    CDC sponsors Disabilities Prevention categorical grants. Thirty States participate and have research and surveillance systems for traumatic brain injury, spinal cord injury, spina bifida, cerebral palsy, fetal alcohol syndrome, Down syndrome, mental retardation, and sickle cell anemia.

    Subsequent to the meeting, one participant sent a letter proposing a way to generate longitudinal data from States. The idea is to identify at least several States (preferably large ones) that have maintained strong data sets on persons with disabilities. Such data sets could be pooled across a specified number of years. The model for this is the DHHS' Administration for Children and Families MultiState Data Archive on foster care.

    One largely untapped area is proprietary data bases. It was suggested in the meeting that private firms might be more willing to make their data available if they got some tangible return. Also, the incentive to share data might be enhanced if it were possible to pool data from several sources (e.g., a group of employers) to preserve anonymity.

    E. Analyses

    The potential for analyses of data on disability issues is great. Several specific suggestions emerged from the participants.

    • Identify the top ten questions of disability policy interest and invite researchers to address them. For example, the National Institute on Aging supports nine Demography on Aging Centers around the country; they are available as resources for analyzing policy issues on elderly persons with disabilities, as well as conducting basic research.

    • Use new techniques of computer mapping to highlight geographic areas of high and low disability rates.

    • Emphasize basic research on the processes of disability.

    • Develop more theory-driven and hypothesis-driven surveys on disability rather than trying to answer every conceivable question. Often survey development is guided by policy issues which prove to be transitory. Survey data should focus rather on longer term issues and concerns that undergird policy development.

      NHRS and AHEAD are examples of surveys that were developed around theories about the decision to retire (e.g., structural models of utility functions) and hypotheses about consumption, saving and intergenerational transfer patterns among the elderly.

    • Use disability data to monitor the differential impacts of cutbacks in public programs, to evaluate program effectiveness and to improve program operations.

    • While additional data on disability are needed, more could be done to analyze existing data. In fact, in an era of cutbacks more will have to be done to analyze existing data.

    III. ASPE FOLLOWUP

    Some comments were offered on the background paper Disability Data for Disability Policy: Availability, Access and Analysis, prepared by DALTCP staff. While generally well-received, the paper was faulted for failing to highlight problems with self-reported data on functional status. There was some question about the advisability of oversampling based on functional status, since the measures are inherently "soft" and since functional status itself is very changeable. Also, it was noted that too little attention was paid to the need for data on pre-disability and post-disability status and to longitudinal data overall.

    Participants throughout the day identified actions that ASPE might take to foster disability data development and analyses. One post-meeting correspondent supported the creation of a single agency to manage Federal statistical programs and respond to policy research priorities. Advisory focus groups of key constituencies (e.g., the disability community, State and local officials) could be tapped to identify emerging policy initiatives and service delivery models as input into survey design.

    Other actions discussed at the meeting included the following:

    • Bring together State officials, private sector representatives and members of the disability community to discuss data design and data access issues.

    • Provide technical support to State data initiatives.

    • Conduct smaller meetings devoted to the data needs of specific groups of persons with disabilities.

    • Promote faster access to Federal data sets through such mechanisms as early results workshops. A current candidate for release of public use tapes as soon as possible is the Disability Survey.

    • Facilitate linkages between survey data and administrative records; e.g., Medicare and Medicaid claims data. Also, try to broaden the kinds of information collected for administrative purposes; e.g., by routinely including health and functional status in administrative records.
