Objective: to assess skills, satisfaction, self-confidence and experience with debriefing of nursing professionals in a simulated scenario for hospital admission of patients with COVID-19. Method: this is a quantitative, observational, cross-sectional study, carried out at a university hospital with nursing professionals. Data were collected in June 2020 using the following instruments: sociodemographic questionnaire, checklist for assessing patient admission skills, the Student Satisfaction and Self-Confidence in Learning Scale and the Debriefing Experience Scale. Subsequently, the collected data were analyzed using descriptive and analytical statistics. Results: sixty-two professionals participated, 23 (37.10%) nurses and 39 (62.90%) nursing technicians, with an average age of 36.82 (±6.19). Compliance with patient admission skills ranged from 66.13% to 90.32%. The overall average score on the Student Satisfaction and Self-Confidence in Learning Scale was 4.46 (± 0.36) and, on the Debriefing Experience Scale and factors, 4.63 (±0.33). Professionals who updated themselves with scientific articles and protocols obtained a higher average score on both scales (p<0.05). Conclusion: most professionals demonstrated skills on patient admission, satisfaction with learning, self-confidence in the simulated scenario and adequate experience with debriefing.
