In situ simulation improves perceived self-efficacy of OR nurses and anaesthesiologists during COVID-19 pandemic

Self-efficacy is defined as people's internal beliefs about their ability to have an impact on events that affect their lives. As part of the COVID-19 pandemic, we carried out in situ simulation for anaesthesiologists and operating room (OR) nurses. Simulation was focused on the recommendations on the use of specific personal protective equipment (PPE) as well as on airway management and intubation. We hypothesised that in situ procedural simulation should increase their perceived self-efficacy.

Between 16 March and 20 March 2020, 208 healthcare workers took part in in situ procedural simulation. A questionnaire was sent to participants on 21 April 2020. Six self-efficacy items related to PPE and airway manoeuvres were assessed before and after training on a Numeric Rating Scale from 0 to 10.

Sixty-seven participants (32%) replied to the questionnaire. The before-after comparison of the six items revealed an increase in perceived self-efficacy for each of them. A before training difference was observed between nurses, board-certified anaesthetists and trainees in anaesthesia in perceived self-efficacy for putting on (6 (3-8) vs 4.5 (2.25-6) vs 2 (0-6), p=0.007) and remove PPE (8 (5-8) vs 4.5 (3.25-6) vs 4 (1-6), p=0.009). No difference in perceived self-efficacy after training was observed between nurses, board-certified anaesthetists and trainees in anaesthesia.

In situ simulation improves the perceived self-efficacy of OR nurses and anaesthesiologists on specific skills related to the care of patients with COVID-19.
