IntroductionThe Personal Protective Equipment (PPE) is essential to avoid the COVID-19 spread to health care workers. Its use can be difficult, posing a high risk of contamination, mainly during doffing, then with the risk of becoming infected.MethodsWe conducted a prospective before-and-after design that used clinical simulation as a research methodology in a clinical simulation center of Colombia. A simulation-based educational intervention with two cases related to COVID-19 was proposed in the emergency room and the intensive care unit. We conducted A workshop for donning and doffing of personal protective equipment (PPE) and a debriefing after the first case.ResultsIn the pre-test, 100% of participants failed donning and doffing PPE, 98.4% were contaminated, only one-person did not contaminate out of. The mean cognitive load was high (7.43±0.9 points). In the post-test, 100% were successful in donning the PPE and 94.8% in doffing; only 9.8% were contaminated. The mean of the cognitive load was low (4.1±1.4 points), and the performance was high (7.9±1.1). Of the total, 73.8% of participants reported overload in the doffing. The most difficulties were in gown/overall, and N95 mask removal.DiscussionThe PPE donning and doffing is critical and may be changed significantly by active training. In responding to the current COVID-19 pandemic in 2020, activities of training in donning and doffing PPE would provide a means of training personnel, reducing the cognitive load and maybe the risk of contamination and infection of health care workers.
