| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 107 === Teamwork in the emergency room is critical. Provided with a good teamwork, timely and appropriate emergency medical treatment can be provided, and the fatality rate can be reduced. The research hypothesis of this work is that there is certain relationship between team dynamics and team performance. In this research, observation is through videos collected in the resuscitation room in the National Taiwan University Hospital. There are 33 video clips in total of patients with Out of Hospital Cardiac Arrest. After using Mask R-CNN to detect members in videos and post-processing for compensating lost detections, the average location of members is used as the representation of the team center for the calculation of the spatial entropy. The entropy represents the spatio-temporal complexity of the team dynamics. The entropy were compared with team performance scores determined by emergency medical professions. Different observation periods, sampling intervals and number of members were studied. Preliminary results show that entropy could indicate team dynamics. For future studies, more cases could be studied and the specific study on the team leader could be important for improving medical teamwork in the emergency room.
