Discussions of hospital quality, efficiency, and nursing care often taken place independent of one another. Activities to assure the adequacy and performance of hospital nursing, improve quality, and achieve effective control of hospital costs need to be harmonized. Nurses are critical to the delivery of high-quality, efficient care. Lessons from Magnet program hospitals and hospitals implementing front-line staff–driven performance improvement programs such as Transforming Care at the Bedside illustrate how nurses and staff, supported by leadership, can be actively involved in improving both the quality and the efficiency of hospital care.
