Abstract：Objective To evaluate the effectiveness of the virtual ultrasound model in standardized training and assessment of obstetric ultrasound skills for first-year residents.Methods A total of 14 residents who participated in the standardized training program at Peking Union Medical College Hospital starting from October 2022 were selected.The virtual ultrasound model was used as a teaching tool for obstetric ultrasound education.Two evaluators with over 10 years of ultrasound experience carried out objective assessments independently.Pre-and post-training assessments were performed and analyzed.Questionnaire surveys were used to record self-assessments by the residents and their evaluation of the effectiveness of virtual ultrasound model education.Results There were strong agreements between the evaluators in both assessments,with intraclass correlation coefficients(ICC)of 0.900 and 0.785 for pre-and post-training scores,respectively.After training,there were significant improvements in the total assessment scores and scores for each element[83.5 points,IQR:74.1～89.4)vs(99.0points,IQR:95.5～99.5),P=0.001)].The total scan time for late pregnancy examinations by the residents decreased significantly after training[(21.5±11.5)min vs(14.6±5.6)min,P=0.009)].The residents believed that the virtual ultrasound models effectively improved scanning techniques and increased confidence in obstetric examinations.Conclusion Virtual ultrasound models can be used for standardized training and assessment of obstetric ultrasound for first-year residents,providing an effective tool to enhance their clinical competency.
