A nursing home is a facility for the residential care of older people, senior citizens, 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 require care that is hard to provide in a home setting. The nursing home staff attends to the patients' medical and other needs. Most nursing homes have nursing aides and skilled nurses on hand 24 hours a day.
