Dataset: National Long-Term Care Survey (NLTCS)

Basic Information
Dataset full name: National Long-Term Care Survey
Dataset acronym NLTCS
Summary The NLTCS is a detailed longitudinal survey that permits observation of changes in the health and functional status of adults ages 65 years and older. The survey also tracks health care expenditures, Medicare services use, and the availability of formal and informal caregiver services. Older adults without impairment living in communities and those residing in institutions are represented in the sample. The survey divides the sample into three cohorts as individuals without disabilities, individuals with disabilities living in the community, and individuals with disabilities living at institutions. Data can be linked with Medicare files such as the Carrier Claims Record, Clinical Labs, Denominator File, Durable Medical Equipment, Home Health Agency, Hospice, Inpatient, Outpatient, Skilled Nursing Facility, and Vital Statistics File. The NLTCS concluded in 2004.

Strengths and limitations
Strengths Longitudinal data with a high relevance to rehabilitation research. Data can be linked with Medicare Standard Analytical Files (SAF), including the Carrier Claims Record, Clinical Labs, Denominator File, Durable Medical Equipment, Home Health Agency, Hospice, Inpatient, Outpatient, Skilled Nursing Facility, and Vital Statistics File. These linkages provide medical expenditure information. Adequate documentation is available.
Limitations Most recent data available from 2004.
