How we talk : aspects of communication and team cognition of trauma resuscitation teams

• A trauma team consists of professionals assembling in an ad hoc manner to resuscitate a patient with life-threatening injuries. In such a team, how the team manages to use non-technical skills, such as communication is important to achieve task management and decision making.  Communication is practised in simulations, and the simulation environment has also been used in research to understand teamwork processes. This thesis is based on video observations of trauma teams working in real life (IRL) and in situ simulations of trauma resuscitations. The aim was to assess the creation of team cognition IRL and in simulation, to analyse verbal communication in the teams and the effects of real-time communication on team structure. In Study I, a grounded theory analysis was undertaken to understand how verbal and non-verbal interactions create team cognition. The analysis resulted in a theory pointing to “split vision” as a team’s ability to alter process modes between team positioning and sensitivity to the patient that was dependent on patient and situational values absorbed from team members’ implicit actions. In Study II, the verbal response modes taxonomy was applied to analyse both the grammatical and pragmatic meaning of verbal interactions that were compared between team roles. In the six most communicative team roles in the context of IRL trauma teamwork, pure mode communication dominated the way of delivering messages. In Study III, the structures of four IRL and four simulated trauma teams were analysed using a social network analysis of real-time communication. Overall, the teams were highly centralised, with the examining physician functioning as an information hub. In Study IV, communication from the same teams was categorised according to information and task management, as well as different coordination behaviours. We compared the IRL and simulation domains based on the proportions of utterances of each category/code, and found that “Give information after request” and closed-loop communication were more prevalent in simulation. Observing real-time communications using different methodologies gave a perspective on the conditions and possibilities for adaptation in terms of work prescriptions and team training, such as room for more communication and possible congestions of nodes in terms of occupancy and tacit communications and working modes thus far unnoticed by us and unreported. Such understanding complements established knowledge about coordination behaviours and interactive team cognition and should be taken into consideration in the practise and training of trauma teams.
