Assiste living residences or assisted living facilities (ALFs) provide supervision or assistance with activities of daily living (ADLs); coordination of services by outside health care providers; and monitoring of resident activities to help to ensure their health, safety, and well-being. Assistance may include the administration or supervision of medication, or personal care services provided by a trained staff person. Assisted living as it exists today emerged in the 1990's as an alternative on the continuum of care for people who cannot live independently in a private residence, but who do not need the 24-hour medical care provided by a nursing home. Assisted living is a philosophy of care and services promoting independence and dignity.
