To describe the level of satisfaction of nursing students with clinical simulation in their undergraduate training.a descriptive observational study of a retrospective cross section was conducted in undergraduate students in Nursing during the academic years 2016-17 and 2017-18. The instrument used was the High Fidelity Clinical Simulation satisfaction scale in students (ESSAF), a validated, anonymous and self-administered questionnaire (alpha .857) to measure the level of satisfaction after high-fidelity clinical simulation practices.Data were collected from a total of 269 students, of which 63.3% were women and the average age of the sample was 21.68±13.46 years. The analysis of frequencies shows results of the grade of satisfaction over 89%, especially in decision-making, the ability to prioritize and learning procedures. Of the answers, 87% exceeded an average of 4 out of 5. The questions in the questionnaire with answers higher than 4.6 were the realism of the cases (4.71), the teacher provides constructive feedback after each session (4.65), the simulation relates theory to practice (4.72), the analysis (debriefing) at the end of the session helps reflection on the cases (4.65) and practical utility (4.69).Nursing students from the University of Cantabria (Spain) report high satisfaction in high fidelity clinical simulation, confirming its usefulness in the learning process.
