Abstract: The 1989 National Long-Term Care Survey (NLTCS) is the third round of data collection on a national sample of elderly persons at risk of or already experiencing chronic impairments (see the NATIONAL LONG-TERM CARE SURVEY, 1982-1984 [ICPSR 8654]). The population of interest is persons aged 65 years and older who have functional impairments, as measured by the Activities of Daily Living (ADL) or Instrumental Activities of Daily Living (IADL) scales. The 1989 NLTCS collected longitudinal data on those elderly persons who in 1982 or 1984 had been identified as functionally impaired or institutionalized. Additionally, the 1989 Screener was used to identify other persons in the sampling frame who, although functionally unimpaired or under age 65 in 1984, had by April 1988 turned 65 and developed functional impairments or were institutionalized for long-term care. The 1989 Institutional Questionnaire obtained data on the institutionalized persons' cognitive functioning, ADL status and care, admission and payment for the care, income and assets, and the institution's certified beds. The 1989 Community Questionnaire collected data on the noninstitutionalized impaired persons' medical conditions, ADL and IADL, help with these activities, range of motion and impairment, other functioning, housing and neighborhood characteristics, health insurance, medical providers, prescription medicines, cognitive functioning, military service, ethnicity, and income and assets. For those community-dwelling respondents who reported help by informal caregivers, interviews were sought with the caregiver who provided the most hours of unpaid help. All persons for whom 1989 information was collected on any of the data collection instruments (Screener, Community Questionnaire and Caregiver Selection Procedure, Survey of Informal Caregivers, and Institutional Questionnaire) are represented in Part 1, the Main Data File, by one record with Screener variables, followed by data from the interviewer's control card and other instruments as applicable. Medicare Parts A and B administrative records from 1988 to 1991 are located in five separate files (Parts 2-6) according to service type (home health, hospice, inpatient, outpatient, and payment). These files are linked to one another and to the main data file via a common anonymous identifier. Part 7, the Analytic File, includes administrative and analytic information on deaths, longitudinal weighting, health, functioning, and special equipment variables for the 1982, 1984, and 1989 surveys and allows the user to choose from a wide array of options for examining the health and service use of the aged population. The user should be cautioned that these variables, in combination, are the product of analytic decisions by the investigators. In addition, hardcopy supplemental documents are included. They include a Source and Accuracy Statement for the 1989 Long-Term Care Survey, a January 3, 1990 memo from the Census Bureau, a list of Social Security Administration state codes, occupation and industry codes, a listing of old and new codes for medical conditions, a Census Bureau memo on caregivers in the 1989 Long-Term Care Survey, and a memo on transition weights.

SOURCE: personal interviews and administrative records

UNIVERSE: Persons 65 years of age on April 1, 1989, dwelling either in institutions or in the community in the 50 states of the United States.

SAMPLE: Multistage screening sample, with both longitudinal and supplemental components, based on an original 1982 sampling frame of approximately 36,000 names drawn from the Medicare Health Insurance Skeleton Eligibility Write-Off (HISKEW) file. The 1989 sample of elderly persons (aged 65 and over) was composed of two main parts: (1) screening and reinterviews, as applicable, of chronically impaired respondents identified by the 1982 and 1984 Screener, Community, and Institutional Surveys, and (2) screening of additional cross-sectional samples of persons who had not reported functional impairments nor been institutionalized in 1982 or 1984, or who had been 61-64 years old in 1984 and ''aged into'' the HISKEW file, followed by interviews with those identified as eligible for the Institutional, Community, or Informal Caregivers questionnaires. Of the respondents to the 1989 Screener who were identified as functionally impaired, questionnaire data were collected on 1,354 institutionalized persons and 4,463 community-dwelling persons (3,456 are complete) and 1,006 of their informal caregivers (898 are complete), with the remainder screened out as nonimpaired, deceased, or interviews not conducted or completed.

NOTE: Parts 1 and 7 have corresponding machine-readable codebooks, while Parts 2-6 are documented by a hardcopy codebook. The questionnaires are available only in hardcopy form upon request from ICPSR.
