Abstract: Objective By analyzing the results of cardiopulmonary resuscitation(CPR)in clinical skills assessment of residents in Beijing Children's Hospital Affitiated to Capital Medical University who participated in standardized training from 2014 to 2018,the theoretical basis for optimizing the training program was provided.Methods The assessment results of CPR was carried out in 323 traineess in Beijing Children's Hospital from 2014 to 2018 as the research data,the assessment results were analyzed by retrospective analysis.Descriptive statistics,one-way ANOVA and two-way ANOVA were performed using SPSS 21.0 and Excel 2007 software.Results The average scores from 2014 to 2018 were 83.14,89.46,89.71,84.52 and 87.75 respectively,and there were significant differences (F=14.93,P<0.01);the average scores of the four groups were 86.93,85.91,89.01 and 89.47 respectively,and there were significant differences(F=4.87,P<0.01); the impact of assessment year (F=12.09,P<0.01) and the source of trainees (F=3.69,P=0.012) on the difference in performance score was statistically significant.Conclusions The standardized training base of pediatric resident should optimize the training program according to the training outcomes,increasing the training frequency of CPR appropriately,and impliment multi-level targeted training.
