191 A prospective observational multicentre study concerning non-technical skills in robot assisted radical cystectomy versus open radical cystectomy. Our hypothesis are: 1. The introduction of Robot assisted surgery leads to an initial decay in Non-Technical Skills behaviour during the learning curve of the team. 2. In experienced robot assisted surgery teams Non-Technical Skills behaviour is more explicitly expressed compared to experienced open surgery teams. 3. The introduction of Robot assisted surgery leads to the development of different forms of Non-Technical Skills behaviour compared to open surgery. The results of this study could possibly be used to develop team-training programs specifically for the introduction of the surgical robot in relation to changes in Non-Technical Skills. Additional technical skills analysis using the intra-corporal footage of the surgical robot will be used to elucidate the role of surgical skills and surgical events on Non-Technical Skills. Design The present study is a prospective observational multicentre non-randomised case control study that will include all patients undergoing either an Open Radical Cystectomy (Open Radical Cystectomy) or Robot Assisted Radical Cystectomy (Robot Assisted Radical Cystectomy) in Catharina Hospital Eindhoven and in Antoni van Leeuwenhoek Hospital. Time line The inclusion will be from January 2021 until August 2022 in both hospitals simultaneously (figure 1). The video collection will start once the first patient is included and will continue until the last patient has had his surgery. Follow-up data collection will start in February of 2021 and will continue until December of 2022. Data analysis will start in January 2022. Figure 1 timeline of the study
