“…During resuscitation, the use of closed-loop-communication is advocated to avoid errors (Fernandez Castelao et al, 2013). This clear, structured, and standardized form of communication (Brindley & Reynolds, 2011;Härgestam, Lindkvist, Brulin, Jacobsson, & Hultin, 2013) consists of an initial message (call-out) by the team leader, which should be confirmed or acknowledged by the receiver (check back) and confirmed once again by the team leader (closing the loop) (Davis et al, 2017;Härgestam et al, 2013;Jacobsson, Hargestam, Hultin, & Brulin, 2012;Schmutz, Hoffmann, Heimberg, & Manser, 2015). Hence, in general, various studies from different fields suggest that effective and less effective action teams differ in both the content and structure of their team interaction.…”
