Objective To evaluate the educational effectiveness of feedback debriefing in clinical training.Methods Forty medical students and fifteen teachers were enrolled in the 2015 after-internship clinical training,which was newly designed to obtain the debriefing part.The test scores and single technical practices were collected and analyzed,before and after the training.DASH scoring system was used to evaluate the effect of debriefing in the team simulation.Results were statistically analyzed by SAS 9.2(SAS institute Inc).Quantitative data were described by x ± s,while qualitative data were described by number and/or constituent ratio.Student's t test and Wilcoxon rank sum test were applied as needed.A P-value ＜ 0.05 was considered to be significant.Results The scores of the students before and after the assessment were (41.88 ± 8.54) vs.(65.06 ± 13.83),and the difference was statistically significant(P=0.000).Individual skills before and after the course had a different degree of improvement.The average DASH-scores evaluated by the students,teachers and supervisors were (39.3 ± 2.12) (very good),(35.1 ± 4.18) (good) and (37.2 ± 3.03)(very good),separately.Conclusions Potent debriefing helps to improve the effectiveness of simulationbased clinical training.

Objective:To analyze the epidemiological characteristics of etiology from patients with hand, foot and mouth disease(HFMD) in ji’an of Jiangxi from 2013 to 2020, and provide effective prevention and control measures for the diagnosis and treatment of HFMD in the region.Methods:We collected 5089 stool and other clinical specimens from patients with HFMD. Fluorescence quantitative PCR was used for enterovirus detection and typing, SAS statistical software was used to analyze the epidemiological characteristics of pathogens from the types of specimens, time, age, gender, and regional distribution.Results:A total of 3 062 positive samples for enterovirus (EV) were detected out of 5 089 samples, with a total positive rate of 60.17%. The proportions of EV71, CoxA16 and other enteroviruses were 15.15%, 16.36% and 68.49%, and other enterovirus infections were the main ones; the positive rate of enterovirus showed a downward trend from 2013 to 2020; the difference in the positive rate of enterovirus in different years was statistically significant ( χ2=118.47, P<0.05). In the past 8 years, the EV71 type of HFMD in Ji’an showed a downward trend year by year. The number of positive cases was mainly concentrated in April-November, with the peak around May and September. There was no significant difference in the positive detection rate between male and female ( χ2=3.44, P>0.05). The positive rate of stool, anal swab and herpes fluid was higher than that of throat swab, and the difference was significant ( χ2=78.76, P<0.01). Conclusions:In recent years, the surveillance result showed that the pathogenic spectrum of enterovirus had changed in Ji’an, relevant surveillance should be carried out according to the actual situation of HFMD etiology in this region, which is conducive to the prevention and control of HFMD in this region.
