BACKGROUND A head nurse (as known as a chief nurse) in charge of nursing in a hospital is the head of the nursing staff and a registered nurse who supervises the care of all the patients, usually in a ward, or a health care facility [1]. Traditionally, head nurses wore a dark-blue dress that was usually darker than that of her subordinates in addition to a white-starched hat [2] and usually provides strong leadership and acts as a link between board-level nurses and clinical practice [3]. In the US military hospitals, head nurses are charged with the responsibility of making twice- daily rounds to supervise the nurses' duty performance [4]. Many large healthcare organizations such as medical center also have this kind of head nurses in healthcare service. They supervise a particular service and have insights into the facility or system such as surgical services, women's services, emergency services, critical care services, etc. As of May 10 in 2018, 415 papers were found in Medline by searching keywords of (head nurse[Title]) OR chief nurse[Title] . However, only 18 exist with keywords of ((head nurse[Title]) OR chief nurse[Title]) and performance. Englebright and Perlin [5] explored characteristics of head nurse required for success in those increasingly responsible and visible roles. Melnyk and her colleagues [6] addressed that head nurses and hospital administrators need to invest in providing resources and an evidence- based culture so that clinicians can routinely implement evidence-based practice as the foundation of care to achieve higher healthcare quality and safety along with decreased costs.

Methods: An approach to assess the management ability of nurse heads was to collect data evaluated by nursing supervisors on 5-point ten management core axes in hospital. We analyze (1) the relation of Cronbach’s  and Kendall’s coefficient of concordance; (2) performance presentations on Google maps with visual displays; (3) the association between summation scores and the age of nurse heads. Results: We found that (1) the relation between Cronbach’s  and Kendall’s coefficient is significantly strong(r=0.61, t=5.87) in concordance(Kendall =0.85, 2  =100.38,df=59, p< .0001); (2) the dashboard shown on the Google map with multidisciplinary functionalities is merit; (3)the association between summation scores and the age is trivial (r=0.18, t=1.5) without concordance(Kendall =0.59( 2  =76.33, df=65, p=0.16). Conclusion: The demonstration of performance sheet is shown on Google maps with a dashboard. The Kendall’s coefficient of concordance can be used for an example in assessing the selection of the nurse head in the hospital as well as in evaluating many kinds of competition judged by referees in the future.
