目的 比较5G远程互动可视化重症超声线上培训与传统的重症超声线下培训的教学效果和学员满意度。方法 选取2022年5月至2023年2月参加北京大学人民医院重症超声培训的100名学员作为研究对象。采用试验对照方法,以参加5G远程互动可视化模拟与实践超声系统进行培训的50名学员作为试验组,以参加传统线下学习班授课形式进行培训的50名学员作为对照组。比较培训前后所有学员的重症超声考核总成绩;比较培训后两组学员的考核成绩,以及两组学员对各自培训方式的满意度。统计分析采用χ2检验和t检验。结果 所有学员培训后的总成绩高于培训前[(86.2±7.3)分比(41.9±11.6)分],差异具有统计学意义(P<0.001)。试验组和对照组学员培训后总成绩分别为(86.9±7.8)分和(85.6±6.8)分,对各自培训方式的满意度评分分别为(42.5±2.5)分和(42.4±3.4)分,差异均无统计学意义(均P>0.05)。结论 5G远程互动可视化重症超声线上培训方式的实施效果与传统线下培训相当,学员满意度较高,可以为重症超声培训方式的选择提供参考。
Objective To compare the teaching effect and satisfaction between 5G remote interactive visual critical ultrasound online training and traditional offline training. Methods A total of 100 trainees who participated in critical ultrasound training organized by Peking University People's Hospital from May 2022 to February 2023 enrolled in the study. Fifty trainees allocated as study group were trained using a 5G remote interactive visual simulation and practical ultrasound system, while the other 50 trainees allocated as control group were trained using offline training. The total score of critical ultrasound for all trainees before and after training was compared. The assessment results after training, as well as their satisfaction with their respective training methods were compared between the two groups. Statistical analysis adopted χ2-test and t-test. Results The total score of all trainees after training was higher than before training [(86.2±7.3) points vs. (41.9±11.6) points, P<0.001]. The total scores of the study group and the control group after training were (86.9±7.8) points and (85.6±6.8) points, respectively; The satisfaction scores for their respective training methods were (42.5±2.5) points and (42.4±3.4) points (both P>0.05). Conclusions The effectiveness of 5G remote interactive visual critical ultrasound online training is comparable to traditional offline training, with high student satisfaction. This can inform the selection of critical ultrasound training methods.
