Note from the National Guideline Clearinghouse (NGC): The Alzheimer's Association commissioned a literature review on end-of-life-care for nursing home residents with advanced dementia. The review was prepared by Ladislav Volicer, M.D., Ph.D. (see "Availability of Companion Documents" field).
Potentially useful articles in literature from 1994 to 2004 were collected from a Medline search and additional sources. The Medline search used a combination of terms such as dementia, Alzheimer's disease, end-of-life care, hospice, and cardiopulmonary resuscitation/CPR. This search yielded 150 citations. Additional citations were identified by searches of identified articles' reference sections, searches of reference sections of practice guidelines ("Care at the End of Life" published by the American Medical Director's Association, "Guidelines for a Palliative Approach in Residential Care" published by the Edith Cowan University, Australia), search of "Hospice and Palliative Care in Alzheimer's Disease" resource list prepared by the Alzheimer's Association Green-Field Library, and by search of the author's private data base. These searches resulted in the collection of 300 articles. Some of these articles report studies in general nursing home populations, which include but are not limited to residents with dementia. However, since more than half of nursing home population has some cognitive impairment, these articles are relevant to the current topic.
All of these articles were reviewed for relevance to the current topic and for inclusion of research data. Articles were included for discussion in the review only if they contained new information obtained by experimental or quasi-experimental methods. Most relevant review articles were included if they contained information about research results obtained before 1994 that is still the state of the art. This selection process resulted in the inclusion of 158 studies and review articles. Most of these studies are observational studies and only a few include evaluations of new interventions. Almost none of the studies are randomized control trials. There is almost a complete lack of research results concerning management of advanced dementia in assisted living facilities. The only available study indicates that end-of-life care is similar in process and outcomes in residential care facilities, assisted living, and nursing homes except that family satisfaction with end-of-life care was significantly higher in residential facilities and assisted living than in nursing homes. Therefore, most of the information in the review applies to both assisted living and nursing homes.
To extend the knowledge gained through this literature review, Alzheimer's Association staff carried out further qualitative research designed to:
- Determine what practitioners, providers, professionals and researchers believe constitutes quality end of life care for residents with dementia
- Describe perceived public policy barriers to delivery of this care.
The first step was to identify experts who could discuss quality end of life care for residents with dementia and the public policy barriers to delivering this care. Staff accomplished this by identifying people who had published relevant articles in peer-reviewed journals. Alzheimer's staff also contacted key national organizations representing nursing homes, assisted living residences, hospices, and professional organizations and asked them to nominate experts for us to interview. A third method of identifying experts was to ask those interviewed for nominations. Any individual who was identified by two or more experts was asked to participate in this qualitative research project.
Interviews, primarily by telephone, were conducted with 49 experts representing providers and researchers from assisted living residences, nursing homes, hospices, the Veterans Affairs medical system, and academia. Experts interviewed included medical directors, physicians, nurses, social workers, counselors, health consultants, researchers, and members of religious orders. Interviews lasted approximately 1 hour.
The experts were asked a series of open-ended questions related to the following three topics:
- What are the key elements of quality end of life care for people with dementia in nursing homes and assisted living residences?
- What are the key elements of quality care for both groups' caregivers?
- What are the public policy barriers to delivery of quality end of life care for people with dementia in nursing homes and assisted living residences in the US?
