[영문]Anecdotal evidence suggests growing concerns about chief nursing officer (CNO) dissatisfaction, intent to leave, and turnover. However, little evidence documents the magnitude of the problem or whether CNO turnover requires direct action. This article reports the results from the first phase of a three-phase study examining CNO turnover and retention in U.S. hospitals. CNOs were invited to complete an online survey to gather data about their experiences with turnover and to identify CNO retention issues. Our sample includes responses from 622 CNOs employed in hospitals and healthcare systems across the United States. Approximately 38 percent of the respondents reported having left their job?13 percent within two years of the survey and 25 percent within five years of the survey. Of these, approximately one-quarter had been asked to resign, had been terminated, or lost their jobs involuntarily. When asked about the context of their departure, a high percentage reported leaving their position to pursue another CNO position (50 percent) or for career advancement (30 percent); approximately 26 percent reported leaving because of conflicts with the chief executive officer. Of great concern is the finding that approximately 62 percent of respondents anticipate making a job change in less than five years, slightly more than one-quarter for retirement. Respondents clearly indicated that CNO turnover was a problem that requires attention. The knowledge gained from this study can be used by healthcare leaders to develop strategies and policies aimed at recruiting and retaining CNOs and easing the transition for CNOs and others in the organization when CNO turnover does occur
