Objective　To explore application on improving basic knowledge of clinical scientific research based on PDCA circle in the standardized training of pediatrics residents and to provide scientific basis for improving the capability of clinical scientific research in standardized training of pediatrics residents. Methods　Based on previous research results

the training courses of improving the capability of clinical scientific research based on conception of PDCA were practiced. The examination of basic knowledge of clinical scientific research before and after training and satisfaction questionnaire in pattern

contents

time arrangements as well as effect of training courses were conducted among 22 pediatrics residents from April to July

2017. Data were analyzed using Mean

Standard deviation and proportion for description and the data before and after training were given a independent-sample t test. The training courses were taken for 3 months. Results　①Compared with the training courses before

the average scores of basic knowledge in capability of clinical scientific research were improved after training [(54.14±23.06) vs. (73.63±21.05)]. ② Insufficiency of some basic clinical scientific research knowledge still existed and there was no statistical difference between the results before and after the training in those areas.③ In the standardized training

pediatrics residents were satisfied with the pattern

contents and results of training courses

except for the time arrangement. Conclusion　The training courses based on PDCA circle can significantly improve the capability of clinical scientific research in the standardized training of pediatrics residents.
