Abstract:
Objective To study the effect of case-based learning(CBL) combined with virtual reality simulator in peripheral vascular intervention training for refresher doctors.Methods Total 30 peripheral vascular refresher doctors were selected in department of vascular surgery,Xuanwu Hospital of Capital Medical University and were randomly divided into the observation group(n=15) and control group(n=15).Doctors in observation group were trained by CBL combined with virtual reality simulator while those in control group were taught by traditional teaching method.Theory examination,skill examination in real environment were performed after the training and achievement differences were compared between 2 groups.Questionnaires were given to the simulator CBL group,to learn refresher doctors' recognition of the teaching method and groups were compared using independent samples t test.Results Theory examination average score was (84.5 ± 7.7) in observation group,higher than the score(72.6 ± 8.7) in control group(P=0.024).Skill examination average score was(85.3 ± 9.3) in observation group,higher than the score(70.2 ± 10.2) in control group(P=0.013).Compared with control group,the mean performance errors in training group,the contrast volume,the mean angiography procedure time,the time of X-ray exposure,the total volume of X-ray exposure and the total volume of X-ray exposure every square meter all decreased significantly and the difference was statistically significant.P value＜0.05.100％ (15/15) simulator CBL group refresher doctors recognized CBL combined with vascular interventional simulator teaching method.Conclusions Teaching method of CBL combined with virtual reality simulator can stimulate the refresher doctors' interest in learning and help them master peripheral vascular interventional techniques.
