Human factors are essential to patient and staff safety, particularly during the COVID-19 pandemic with redeployment of staff to different roles in unfamiliar environments 
. With concerns that the second pandemic wave would engender greater pressures on general medical wards, the simulation team at a London teaching hospital set out to create a multi-disciplinary educational programme for ward staff caring for COVID-19 patients. The course, planned for face-to-face delivery, was rapidly converted to online simulation at the height of the pandemic.
The aim of the study was to ascertain the efficacy of converting face-to-face simulation and debriefing into online asynchronous video-based scenarios and debriefing, to enhance understanding of human factors skills.
In October 2020, a half-day simulation course commenced. Due to suspension of face-to-face teaching in December 2020 with COVID-19 cases rising, this was converted into a half-day online format through filming faculty participating in the existing scenarios. These films were shown to participants, followed by asynchronous online debriefing via Microsoft Teams. Both formats had e-learning as a pre-requisite. Data were collected using pre- and post-session questionnaires containing the Human Factors Skills for Healthcare Instrument (HuFSHI) 
. Learners who attended both formats were excluded from quantitative analysis.
Post-training, staff demonstrated improvement in self-efficacy of human factors skills for healthcare. There was no statistical significance between mean improvements for both formats; the greatest improvement was split equally (Table 1). 100% found the face-to-face (N = 24) useful, versus 98% online (N = 54). Communication was the skill most learnt (face-to-face 58%, online 65%), with teamwork (face-to-face 50%, online 48%), escalation (face-to-face 42%, online 57%) and self-care (face-to-face 38%, online 19%) also frequently mentioned. Aspect’s learners’ thought were good included the discussion-based element (face-to-face 50%, online 37%), interactivity (face-to-face 13%, online 31%), multi-disciplinary team involvement (face-to-face 13%, online 20%) and videos for the online format (19%). 21% wanted the face-to-face longer, 15% wanted the online shorter. 9% would rather the online was face-to-face.
Implications for practice:
Online asynchronous debriefing produced similar outcomes to face-to-face for teaching human factors. We posit that this was because the videos were not ‘best practice’ – thus stimulating learning conversations, which accessed learners’ frames and past experiences. Challenges for faculty included: pace and volume of sessions, managing psychological safety, emotive discussions, screen fatigue, and technical aspects. A 6-month follow-up survey is planned and will be included in the presentation. Further work is required to understand why the results were similar.
