A nursing home is a facility for the residential care of elderly or disabled people. Nursing homes may also be referred to as care homes, skilled nursing facilities (SNF) or long-term care facilities. Often, these terms have slightly different meanings to indicate whether the institutions are public or private, and whether they provide mostly assisted living, or nursing care and emergency medical care. Nursing homes are used by people who do not need to be in a hospital, but cannot be cared for at home. The nursing home facility nurses have the responsibilities of caring for the patients' medical needs and also the responsibility of being in charge of other employees, depending on their ranks. Most nursing homes have nursing aides and skilled nurses on hand 24 hours a day.

In the United States, while nearly 1 in 10 residents age 75 to 84 stays in a nursing home for five or more years, nearly 3 in 10 residents in that age group stay less than 100 days, the maximum duration covered by Medicare, according to the American Association for Long-Term Care Insurance. Some nursing homes also provide short-term rehabilitative stays following surgery, illness, or injury. Services may include physical therapy, occupational therapy, or speech-language therapy. Nursing homes also offer other services, such as planned activities and daily housekeeping. Nursing homes may offer memory care services, often called dementia care.
