Impact of the nurse shortage on hospital patient care: comparative perspectives.

National surveys of registered nurses, physicians, and hospital executives document considerable concern about the U.S. nurse shortage. Substantial proportions of respondents perceived negative impacts on care processes, hospital capacity, nursing practice, and the Institute of Medicine's six aims for improving health care systems. There were also many areas of divergent opinion within and among these groups, including the impact of the shortage on safety and early detection of patient complications. These divergences in perceptions could be important barriers to resolving the current nurse shortage and improving the quality and safety of patient care.
