231 Figure 3 - Flowchart of the participants in the first (A) and second (B) phases of the training. Souza-Silva et al. Simulation training for myocardial infarction Int J Cardiovasc Sci. 2019;32(3)227-237 Original Article To highlight the improvement in the professionals’ knowledge acquisition, a comparative analysis of the total number of correct answers in both tests was performed and is shown in Table 1. An increase in the number of correct answers was observed in the post-test when compared to pre-test, with a median of 6 right answers in the pre-test (interquartile range [IQR] 5-7) and 7 in the post-test (IQR 6-9) (p < 0.0001). In addition, the lowest score comprised two correct answers to questions in the pre-test and increased to four in the post-test. Based on the type of question, an individual analysis showed an increase in the number of correct answers in 8 out of 10 questions (p < 0.05). As for the remaining questions, in one of them the number of right answers in the pre-test was high (97.4%) and remained high in the post-test results (99.4%). In the last question, the number of correct answers remained low in both tests, as shown in Table 2. No correlation was observed between years of work experience (Spearman -0.058, p = 0.53) or workplace (Spearman -0.034, p = 0.71) and knowledge acquisition. These results were similar when assessing only medical doctors (occupation time Spearman’s = -0.041, p = 0.75; workplace Spearman’s = -0.10 p = 0.42). Second phase A total of 252 professionals participated in the first training session, of which 81 were doctors and 171 nurses. Two-hundred and forty-two professionals (75 doctors and 167 nurses) answered both tests, which corresponded to 96% of the total (Figure 3). The profile analysis of physicians (n = 75) revealed that most were males (76.0%). There was a predominance of the ambulance service professionals (51.0%), followed by hospital employees (45.0%) and 21.0% had graduated up to one year before, 41.0% had graduated 2 to 5 years before, 20.0% had graduated 6 to 10 years before and 17.0% had been working for more than ten years in the profession. As for nurses, the analysis of their profile (n = 167) indicated that most were women (58.0%), with a predominance of professionals working in hospitals (73.1%) followed by those working in ambulance services (25.7%). Ten percent had graduated up to one year before, 42.0% had graduated 2 to 5 years before, 42.0% had graduated 6 to 10 years before and 5.0% had been working in the profession for more than ten years. In the comparative data analysis shown in Table 1, an improvement in the results was observed in the post- test, since 78.0% of the sample (58.0% of physicians and 83.0% of nurses) obtained better results. Medical doctors reached a median of 7 correct answers in the pre-test (interquartile range [IQR] 2-8) and 8 in the post-test (IQR 7-9) (p < 0.0001). Nurses had a median of 6 right answers in the pre-test (interquartile range [IQR] 4-7) and 9 in the post-test (IQR 7-9) (p < 0.0001). Furthermore, as shown in Table 2, the lowest score for physicians was two questions in pre-test and increased to four in post-
