The National Nursing Home Survey (NNHS) is a survey of nursing homes and related care facilities in the United States. During 2004, information regarding facility and financial characteristics was gathered from 1,174 facilities, along with current resident information for 13,507 residents, with additional information from 3,017 Nursing Assistants. The 2004 NNHS, conducted between August and December of 2004, was reintroduced into the field after a five-year break, during which time the survey was redesigned and expanded to collect many new data items using the National Nursing Assistant Survey (NNAS), which was sponsored by the Office of the Assistant Secretary for Planning and Evaluation (APSE) and is the first national study of nursing assistants working in nursing facilities in the United States. Facilities (DS 1) information was gathered through personal interviews with facility administrators and provided information on topics such as certification, availability of beds, and kinds of services provided, including dental, hospice, and nutrition. Current Residents (DS 2) information includes questions regarding age, race, marital status, level of care, and use of aids such as walkers, hearing aids, and crutches. Nursing Assistants (Part 3) information looked at the important role of nursing assistants in providing long-term care services for the growing population of the elderly and chronically ill. The NNAS gathered information regarding recruitment, education, training and licensure, job history, and family life, along with client relations, job satisfaction, and workplace environment.

In preparing the data files for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.

Per agreement with NCHS, ICPSR distributes the data files and text of the technical documentation for this collection as prepared by NCHS.

A sample of 1,500 nursing homes was selected. Of these, 283 refused to participate and 43 were considered out of scope for one or more of the following reasons: the nursing home had gone out of business, it failed to meet the definition used in this survey, or it was a duplicate of another facility in the sample. A total of 1,174 nursing homes participated at the first stage by providing facility information, resulting in a first stage response rate of 81 percent. A total of 14,017 residents were sampled from the responding facilities. Of these, 8 were out of scope and 502 refused, yielding a second stage response rate of 96 percent, and an overall response rate for the resident component of the NNHS of 78 percent.

For the 2004 survey, 1,500 nursing home facilities were selected from a sampling frame of United States nursing homes. The sampling frame was drawn from two sources: (1) The Centers for Medicare and Medicaid Services' Provider of Services file of United States nursing homes, and (2) state licensing lists compiled by a private organization. These two files contained approximately 17,000 nursing homes. The combined files were matched and unduplicated, resulting in a sampling frame of 16,628 nursing homes.
