Afterwards, the refresher course was offered (intervention) and was accessed in accordance with individuals' schedules, during the established time period. At the end of the course, 26 participants answered the post-test. Those who did not participate in the post-tests were excluded from the study, as it is pairwise analysis of the sample.the participants obtained, on average, 55.5% of correct answers in the pre-test on their knowledge, and 73.4% in the post-test, this difference being statistically significant. There was a negative correlation between the time of experience in lecturing and the performance in the test on their knowledge.the participation in the online refresher course contributed to improving the lecturers' performance in the test on their knowledge, in relation to the recommendations for assessing chronic wounds, based in scientific evidence.
