Abstract
A survey by the Japan Council for Quality Health Care (2019) reports that medical adverse events are increasing year by year. The leadership required of chief nurses is patient safety and aiming to provide better nursing care to patients. In the United States, it is recognized that the servant leadership of nursing administrators improves the job satisfaction of nurses who work together and this promotes their growth. It is pointed out that leadership applies as an effective leader image. Therefore, in this paper, in order to realize the medical safety of patients, while focusing on the servant leadership of the chief nurse, a prospect is made based on the discussion points of previous research on assertive communication. As a result, it is suggested that close communication could be practiced by building an assertive relationship between the chief nurse and nurses in the team in the process of demonstrating servant leadership. In other words, the concept of assertion plays a supporting role for chief nurses to demonstrate servant leadership.
