The Influence of Stress on Student Performance during Simulation-based Learning: A Pilot Randomized Trial.

Background: Simulation-based learning is an important educational medium that is being implemented increasingly for the purpose of improved patient care and safety. However, there is evidence to suggest that simulation-based education (SBE) may increase anxiety, as illustrated through self-reporting and physiological responses. Despite such data, no studies have investigated whether anxiety and stress can be manipulated through SBE scenario design and delivery to facilitate optimal learning conditions.

Objective: This pilot study examined perceived anxiety and physiological stress experienced by entry-level physiotherapy students while learning a skill using SBE and the relationship between this anxiety and their subsequent skill performance.

Methods: Final-year physiotherapy students were randomly allocated to one of three SBE experiences: low, medium, or high stress. The experiences were designed to induce increasing levels of stress and anxiety. Performance of the learned skill (endotracheal airway suctioning) was measured after the SBE using a bespoke assessment form. Cortisol levels, heart rate, and perceived anxiety measurements (State-Trait Anxiety Inventory and visual analog scale) were also collected.

Results: Twenty-seven participants completed the trial. There were significant differences in perceived stress and physiological response between the groups. The low-stress group demonstrated significantly better performance of airway suctioning than the higher-stress groups (P = 0.02). Higher anxiety was correlated with poorer skill performance (r = -0.410).

Conclusions: Students report SBE to be stressful, and scenarios themselves can influence the stress and anxiety experienced. Greater stress is associated with poor learning outcomes during SBE. Healthcare educators involved in SBE scenario design need to consider the stress levels experienced. Future research to determine optimal stress and embed measurement of stress in SBE experiences is warranted.
