Trends in the experiences of hospital-employed registered nurses: results from three national surveys.

The comparative results of three national surveys provide the only known source of data describing the evolving state of the nursing workforce over time in this country. These national random sample surveys expose the harmful effects of a lingering shortage of nurses and make plain that much work remains to be done to improve the experiences of hospital-employed RNs. At the same time, nurses and others involved in hospital patient care should be encouraged by the improvements that have been made in recent years, despite the presence of a nursing shortage.
