Hospital care is the most expensive form of health care. It includes ambulatory surgery centres, where patients have operations and return home the same day. Patients who need long-term medical care because of their age or chronic illness may stay in a nursing home. Some patients need regular medical care and other assistance, but are not ill enough for a hospital or a nursing home. Home health care allows them to receive skilled nursing and other care in their own homes. Home care is very popular with patients because most people prefer staying at home, rather than going to a hospital or a nursing home. Hospitals, public health departments, and other organisations also offer home care.
