ABSTRACT BACKGROUND: Because of the social isolation and distancing measures that were imposed to stop the spread of coronavirus disease 19 (COVID-19), new ways of teaching were implemented. OBJECTIVES: To describe the implementation of telesimulation and seek to assess students’ perceptions regarding telesimulation. DESIGN AND SETTING: Retrospective quantitative study conducted within the hospital simulation at a private medical school in São Paulo, Brazil. METHODS: After telesimulation training, students answered a questionnaire that provided an overall assessment of this activity, self-assessment and assessments of the facilitators and infrastructure provided by the University. RESULTS: Among the students, 50% reported that the activity was below expectations and 45% reported that it was in line with their expectations. The strong points of the activity were the clinical cases, workload and teachers. The main challenge was students’ difficulty in reflecting on their learning and the infrastructure. CONCLUSIONS: Since students have less experience and fewer clinical encounters than residents or professionals, they also face more difficulty. Although telesimulation may have provided a valid alternative to replace simulation training during the COVID-19 pandemic, more face-to-face activities should be offered to students, when possible.
