Performance based situation awareness observations in a simulated clinical scenario pre and post an educational intervention

Abstract

This study compared final year nursing students' error rate and use of strategies to maintain SA when undertaking specific nursing care in a simulated clinical environment pre and 10 weeks post a planned SA education intervention. Students were observed using a Performance Based Situation Awareness Observation Schedule (PBSAOS) undertaking two tasks in a simulated clinical environment pre and post the SA education. For task 1, post educational intervention, there was no significant increase in the error rate for any performance measures, and there were significant decreases in the error rates for three performance measures. For task 2, post educational intervention, there was a significant decrease in the error rate for two measures and a significant increase in the error rates for seven performance measures. In considering the overall group error rate when excluding uncompleted tasks, there was a significant (x =.0001) decrease in the error rate for task 1 post educational intervention (41.4% compared to 26.6%), and significant (x =.01) increase in the error for task 2 post educational intervention (39.6% compared to 47.3%). The findings of this study demonstrate that the implementation of an intervention designed to increase SA actually appear to have resulted in hyper-vigilance and subsequent noncompletion of required tasks.

Training situational awareness for scrub nurses: Error recognition in a virtual operating room

“…Based on previous studies related to factors influencing SA (e.g. Endsley, 2012Endsley, , 2015Flin et al, 2008;Gluyas et al, 2019), we expected that participants with higher SA, lower perceived workload, lower anxiety and higher immersion levels in the VR simulator would detect more errors in the OR and more rapidly. We also expected that participants who detected more errors would explore the virtual OR more thoroughly and have a better user experience.…”

“…Among NTS, situation awareness (SA) appears crucial in the OR as it has a direct impact on other NTS such as communication, decision making, leadership and teamwork (Flin et al, 2015;Gluyas et al, 2019;Stubbings et al, 2012). SA is defined as the ability to gather information from the environment, recognize and understand it and anticipate its future J o u r n a l P r e -p r o o f 4 state (Endsley, 1995;Flin et al, 2008).…”

“…SA is a major NTS for scrub nurses who are responsible for hygiene and safety and who are also expected to "think ahead of the surgeon" (Mitchell et al, 2012(Mitchell et al, , 2011. Many factors can have a negative influence on SA (Endsley, 2012;Gluyas et al, 2019): environmental factors (e.g. noise, equipment, time pressure), individual factors (e.g.…”

“…attentional capacity, information overload, task interruptions). Several studies have demonstrated that specific training is required to improve SA (Endsley, 2015;Gluyas et al, 2019;Salas et al, 2008).…”
