Early lessons learnt using simulation to rapidly deploy a trained observer programme during the COVID-19 pandemic in New York City.

New York City became one of the epicentres of the COVID-19 pandemic in 2020. Simulation was used to establish the COVID-19 trained observer programme to mitigate healthcare workers' infection risk during patient care. The members of the trained observer group consisted of 32 staff members. At the start of the training programme, they were provided donning and doffing guides with a step-by-step description of personal protective equipment (PPE) usage, followed by in-situ PPE simulation training. Later on, as PPE protocols evolved, additional educational modalities were used and included training videos, picture demonstrations of common PPE mistakes and repeated in-situ simulations. The early lessons which emerged from using simulation to train observers during the COVID-19 pandemic were the following: address PPE shortages during presimulation planning, prepare to perform updates for trained observers and use multiple educational modalities to train observers. Adequate amounts of PPE should be available to train observers. Repeated simulations are necessary to update observers on PPE protocols. Multiple learning modalities should educate the trained observers and equip them for their role in COVID-19 units.
