BackgroundThe aim of this study is to evaluate effectiveness of ISUOG (International Society of Ultrasound in Obstetrics and Gynecology) basic training curse in Chinese sonographer, which has not been reported yet. MethodsISUOG basic training course includes 30 lectures and was held in 3 days in 2019 in Beijing, China. We included the questionnaires answered by the trainees both before and after the course in each day. There were 9 lectures presented in the first day, 12 in the second and 9 in the last. The theoretical tests were provided by ISUOG, including 22, 21 and 21 multiple-choice questions respectively in 3 days. Pre and post-training theoretical test scores were compared by Wilcoxon singned-rank test. The changes of the theoretical test scores and the rates of “very satisfied” and “very useful” from trainees of different professional titles were compared by Wilcoxon singned-rank test and Chi-square test.ResultsQuestionnaires from 481 trainees who have experience of ultrasonic scan in Ob/Gyn and also had done the survey both before and after course were collected, with 274 in the first day, 94 in the second and 113 in the last. The differences of the correct-answer-number got from the before-test and after-test were with statistically significance(all P-values <0.05). The trainees who got better scores after the training were 219(79.9%), 73(77.7%) and 82(72.6%) in each day, and the changes of scores were without significant difference between doctors of different titles( all P-values >0.05). After every day’s training, the rates as “very satisfied” evaluated by trainees were 81.4%, 87.2% and 91.1% respectively, and the rates as “very useful” were 80.3%, 88.3% and 91.2%. The rate of “very useful” evaluated by trainees of primary title was higher than that of high title, with P-values of 0.01.ConclusionOur results indicated that ISUOG basic training course in China got good feedback and could assist Chinese sonographers in some degree.
