Objective This study aims to determine the mediating effects of psychological empowerment on abusive supervision and turnover intention as perceived by nurses to provide information to change the status of nurse turnover. Methods A cross-sectional survey (a questionnaire examining perceptions of abusive supervision, measurement of psychological empowerment, and questionnaire for turnover intention) was used to collect data. A total of 1127 clinical nurses, who were recruited through convenience sampling, participated in the survey. Results Nurses’ average perceived abusive supervision, psychological empowerment, and turnover intention scores were 1.62 ± 0.95, 3.24 ± 0.83, and 14.17 ± 3.78, respectively. Psychological empowerment was found to mediate the relationship between abusive supervision and turnover intention ( P < 0.01). Turnover intention tends to be stronger and psychological empowerment reduced when nurse managers adopt an abusive leadership style. Conclusions Nurses' psychological empowerment is an intermediary variable that predicts the relationship between abusive supervision and turnover intention. Nurse managers should manage abusive supervision to increase nurses’ psychological empowerment and decrease turnover intention.

For nurse managers wishing to increase nurse engagement and to achieve effective management, both perceived work environment and psychological empowerment are factors that need to be well controlled in the process of nurse administration.

The aim of this study was to evaluate the effect of a preoperative, multidisciplinary intervention program for the prevention of acute postoperative delirium on the incidence and severity in patients who were treated in the intensive care unit after surgery. We studied 122 patients who had been transferred into intensive care unit after surgery at a teaching general hospital in China. The intervention consisted of standardized protocols for the management of risk factors for delirium: education of nursing staff, systematic cognitive caring, maintaining a safe environment, social support, and improving sleep quality. All patients were monitored for signs of delirium after surgery, as measured by the Delirium Detection Score. The Delirium Detection Scores of patients in the intervention cohort after surgery on different time points were less than the scores of patients in the control group on the same point-in-time (p < .01). The severity degree of delirium for patients was less (p < .01) in the intervention group within 24 hours than that in the usual care cohort. This study showed the beneficial effects of a preoperative intervention program focusing on early prevention of delirium in patients before surgery. Systematic and comprehensive interventions could reduce the incidence and severity of delirium.
