Health care systems include a wide variety of organizations, people, and actions whose primary intent is to promote, restore, or maintain health. One way they achieve their goal is by attempting to influence health care legislation to improve laws and regulations through various initiatives, including health care campaigns, lobbying, health fairs, charities, and health improvement educational programs.

Healthcare facilities consisting of multiple services are also known as healthcare systems. For example, a hospital complex that provides inpatient, outpatient, home health, and coordination of services to patients is a health care system. The system of care may be inclusive of care from all points of care on the spectrum, including but not limited to: home care through family care in the community, behavioral health, occupational health, public health, inpatient admission for acute care to the hospital, rehabilitation, or hospice care if restoration of health is not possible.
