The purpose of this thesis is to study the current status and past trend of nursing turnover in Taiwan. The factors affecting nursing turnover are investigated. The research adopts longitudinal methodology and is based on the Medical Staff Database of the Department of Health, from which 420,183 samples between 1999 and 2005 are analyzed. The study results show that: 1. The registered nurses are more than non-registered ones. The average age and seniority of the nursing turnover personnel are 26 and 4.73, respectively. In hospitals, nursing turnover is higher in regional and district hospitals. In non-hospitals, the percentage of nursing turnover in home health care and nursing home is higher and increasing year by year. 2. The nursing turnover rate is closely related with economic growth rate. That is, the more the economic growth, the higher the nursing turnover. 3. With reference point in 1999, the growth rate of nursing turnover is negative from 2000 to 2001 and positive from 2002 to 2005, though a drop of 8.67% happened in 2005 when compared with 2004. Besides, the growth rate of nursing turnover in hospitals is inversely proportional to that in non-hospitals. 4. The policy of Global Budget Payment System has noticeable impact on nursing turnover. The phenomenon is most significant in clinics of the hospital organizations and home health care, nursing home and nursing school of the non-hospital organizations.
