The term “health care system” refers to the organization, financing, payment, and delivery of health care. As described in greater detail in the IOM report Crossing the Quality Chasm: A New Health System for the 21st Century (IOM, 2001), the U.S. health care system is a complex, adaptive system (as opposed to a simple mechanical system).

Throughout this report, the committee highlights what it believes to be one of the strongest linkages that has emerged within the U.S. health care system: that between health reform and the future of nursing. As the report emphasizes, the future of nursing—how it is shaped and the directions it takes—will have a major impact on the future of health care reform in the United States.

Licensed Practical/Licensed Vocational Nurses (LPN/LVNs) provide basic nursing care including monitoring vital signs, performing dressing changes and other ordered treatments, and dispense medications in most states. LPNs work under the supervision of a physician or registered nurse. While there is declining demand for LPNs in hospitals, demand is high in
