Effects of Stress on Team Coordination and Performance

Study Overview
=================
Brief Summary
-----------------
Healthcare teams often encounter challenging circumstances where they must deliver high-quality care. For a team to function effectively, its members must not only be individually competent, but they also need to collaborate and cooperate using their respective expertise. Such teams often work under high stress situations, where they need to make high stakes decisions under conditions of uncertainty, time-sensitivity and variable levels of control. Research shows that such emergency situations provoke stress responses in individuals, which can impair attention, memory, reasoning, and decision-making. However, it remains unclear how individual-level stress responses influence team communication, coordination, and performance. The aims of this study are to a) compare team coordination, communication, and performance in low stress versus high stress simulated emergency situations; and b) characterize the relationship between teams' stress profiles and the teams' performance and coordination. The study will be a within-subject experimental design, with teams serving as their own controls. Teams of emergency medicine residents and nurses will participate in two simulation scenarios: one in a low stress condition, and the other in a high stress condition (counterbalanced across the teams).

Detailed Description
-----------------
Healthcare teams often encounter challenging circumstances where they must deliver high-quality care. For a team to function effectively, its members must not only be individually competent, but they also need to collaborate and cooperate using their respective expertise. Effective teamwork has been demonstrated to have a positive effect on patient outcomes and adherence to treatment guidelines. As a result, team training interventions have become increasingly prevalent in healthcare. These interventions predominantly focus on generic team competencies that can be transported across different situations and team compositions. A recent meta-analysis found that team training resulted in large effect sizes for the learning and transfer of cognitive and skills-based outcomes, but weaker effects on teamwork performance and medical errors. As such, there are calls to better understand the factors that affect teamwork. Teams often work under high stress situations, where they need to make high stakes decisions under conditions of uncertainty, time-sensitivity and variable levels of control. Research shows that such emergency situations provoke stress responses in individuals, which can impair attention, memory, reasoning, and decision-making. However, it remains unclear how individual-level stress responses influence team communication, coordination, and performance. The aims of this study are to a) compare team coordination, communication, and performance in low stress versus high stress simulated emergency situations; and b) characterize the relationship between teams' stress profiles and the teams' performance and coordination. Methods: The study will be a randomized control trial, with teams serving as their own controls. Teams of emergency medicine residents and nurses will participate in two simulation scenarios: one in a low stress condition, and the other in a high stress condition (counterbalanced across the teams). Based on previous similar studies on the impact of stress on individual performance, where large effects sizes are seen (.7 -.75)8, the study will recruit a minimum of 17 teams (two-tailed test, alpha set at .05 and power set at .80). In both low and high stress scenario versions, the underlying mechanism of disease or injury will be identical, as will be the expected clinical management of the situation. Known stressors will be added to the scenarios, ensuring ecological validity (stressors that occur in real life). The stressors will include a) socio-evaluative stressors (presence of other with ability to negatively judge); b) increases in the severity of the situation (unstable patient); c) increases in the stakes (e.g. woman in early stages of pregnancy), d) noise, as well as e) unexpected brief complications (e.g. brief equipment challenge). The participants' subjective (State-Trait Anxiety Inventory- STAI11, cognitive appraisal) and physiological stress (heart rate variability) responses will be measured. Stress responses will be compared at baseline, immediately before, and immediately after each scenario, as well as during for the physiological measures. The team performance will be assessed using the Team Emergency Assessment Measure (TEAM).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Team performance | Team performance will be assessed using the Team Emergency Assessment Measure (TEAM), which was developed to assess the quality of medical emergency team performance. It consists of 12 items. The first 11 items assess leadership, team coordination, team communication, and situation awareness on 5-point Likert scale. The 12th item is an overall measure of a team's performance and scored on a 10-point Likert-scale. Higher scores indicate better performance. The teams performance during the scenarios will be video-recorded and then scored by blinded raters | Over 3 months at the end of the data collection phase. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ratio of information management to task management | Using a structured observation system of team coordination during non-routine events (Co-ACT, Framework for Observing Coordination Behaviour in Acute Care Teams), the investigators will characterize how and when the teams engage in coordination and communication activities that have been linked with high performing teams, but that have yet to be integrated into common healthcare team training approaches. The ratio of information management versus task management will be calculate as the amount of time in which the team members communicate and coordinate actions related to information management versus the amount of time communicating and coordinating actions related to task management. The teams performance during the scenarios will be video-recorded and then scored by blinded raters | Over 3 months at the end of the data collection phase. | 
| Frequency of chances between implicit and explicit coordination | Using a structured observation system of team coordination during non-routine events (Co-ACT, Framework for Observing Coordination Behaviour in Acute Care Teams), the investigators will characterize how and when the teams engage in coordination and communication activities that have been linked with high performing teams, but that have yet to be integrated into common healthcare team training approaches. The frequency of changes between implicit coordination and explicit coordination will be calculated as the number of times, in a given scenario, the team switches from implicit coordination to explicit coordination, and vice-versa. The teams performance during the scenarios will be video-recorded and then scored by blinded raters, | Over 3 months at the end of the data collection phase. | 
| Team heedfulness score | Using a structured observation system of team coordination during non-routine events (Co-ACT, Framework for Observing Coordination Behaviour in Acute Care Teams), the investigators will characterize how and when the teams engage in coordination and communication activities that have been linked with high performing teams, but that have yet to be integrated into common healthcare team training approaches. The degree of heedfulness in the teams will be calculated as the total time that team members engage in heedful behaviours (Noticing and communicating, Anticipating, Maintaining standards, Backup Behaviour, Closed-Loop Communication). The teams performance during the scenarios will be video-recorded and then scored by blinded raters | Over 3 months at the end of the data collection phase. |
