“…More difficult tasks require teams to use more complex interactions and sequencing of skills and knowledge (Wood, 1986). Few studies have examined effects of surgical difficulty on goal attainment in medical settings (e.g., Xiao et al, 1996;Xiao & Mackenzie, 1998), while others examined effects of task difficulty on team performance (e.g., Luciano, Bartels, D'Innocenzo, Maynard, & Mathieu, 2018;Vashdi, Bamberger, & Erez, 2013). Unexpected events have been studied more frequently, providing evidence that distractions, interruptions and complications during surgery harm team performance (Goodell, Cao, & Schwaitzberg, 2006;Healey, Primus, & Koutantji, 2007;Healey, Sevdalis, & Vincent, 2006a;Kurmann et al, 2012).…”
