Objective　To explore the effect of problem-based learning (PBL) combined with video teaching mode on the standardized residency training of digestive operating room. Methods　The study selected 52 digestive operating room residents who participated in the standardized residency training in The First Affiliated Hospital of Air Force Medical University from December

2019 to March

2020 as research subjects and they were randomized into the routine group and the observation group

with 26 residents in each group. The routine group only issued the standardized training materials for learning

and the observation group introduced PBL combined with video teaching mode on this basis

with 1 month of learning time for both group. The scores of theory and practice

the scores of core competence before and after learning and the satisfaction with teaching mode were compared between the two groups. SPSS 24.0 was used for t test

rank sum test and chi-square test. Results The results of theory and practice

excellent and good rate of observation group were higher than those of routine group (P＜0.05). After learning

the scores of basic knowledge reserve

emergency identification ability

event handling ability

field investigation ability and safety protection ability of the two groups were higher than those before learning

of which the observation group were significantly higher than the routine group

with statistical differences (P＜0.05). The satisfaction of the observation group was higher than that of the routine group. Conclusion　PBL combined with video teaching mode can improve the performance and core competence of digestive operating room residents

thus reaching their satisfaction.
