A healthcare institution usually has been thought of as a hospital, a nursing home, a rehabilitation facility, or another such single-site entity. Such an institution consists of the human beings who work in many different capacities within it, the leaders who direct and manage it, and its governing body—usually a board of directors or board of trustees that is responsible for hiring (and firing) the chief executive officer (CEO) or president of the institution and for setting policy and direction in partnership with the employed leaders. Many institutions now, however, are much larger than a single facility.
