PICC置管术虚拟仿真平台的构建及临床培训应用评价

Construction of virtual simulation platform for PICC catheterization and evaluation of clinical training application

目的构建经外周静脉置入中心静脉导管(peripheral inserted central catheter,PICC)置管术虚拟仿真培训平台,并探讨其在临床培训中的应用效果。方法整群选取2020年与2021年参加某省PICC专业技术高级培训班的118名护士参与本研究。其中2020年(n=51)培训以理论授课结合操作实训的形式进行,2021年(n=67)在原有培训形式的基础上引入虚拟仿真平台作为补充。使用SPSS 23.0进行独立样本t检验,比较两年的理论与操作考核成绩,评价平台的应用效果。通过满意度调查和学习日志,了解平台的使用感受。结果2021年参与培训护士的理论成绩为(96.56±3.17)分,操作成绩为(94.06±2.16)分,其中操作成绩优于2020年(t=-11.37,P<0.001),理论成绩差异无统计学意义(t=0.17,P=0.853)。2021年使用虚拟仿真平台的护士中63人(94.0%)认为本平台能辅助提高培训效果;61名(91.0%)护士期待虚拟仿真技术在其他知识的教学与培训中应用。结论虚拟仿真技术作为一种新型的教学形式,能够提升临床护士置管操作培训的效果和满意度,为相关技能培训的开展提供了参考。

Objective To construct a virtual simulation training platform for peripheral inserted central catheter(PICC)catheterization and discuss its application in clinical training.Methods A total of 118 nurses who attended the PICC professional and technical advanced training courses in a province in 2020 and 2021 were enrolled in this study.In 2020,the training was conducted in the form of theoretical teaching combined with practical training(n=51),and in 2021,virtual simulation platform was introduced as a supplement on the basis of the original training(n=67).SPSS 23.0 was used for independent-samples t-test to compare the theoretical and operational assessment results of the two years and evaluate the application effect of the platform.Through the satisfaction survey and learning log,the nurses'experience of using the platform was understood.Results The theoretical performance and the operational performance of nurses who participated in the training in 2021 were(96.56±3.17)and(94.06±2.16)respectively,and the operational performance was better than that of nurses who participated in the training in 2020(t=-11.37,P<0.001),and the difference in theoretical performance was not statistically significant(t=0.17,P=0.853).In 2021,63 nurses(94.0%)who used the virtual simulation platform believed that the platform could assist to improve the training effect;61 nurses(91.0%)expected the application of virtual simulation technology in the teaching and training of other knowledges.Conclusion As a new teaching form,virtual simulation technology can significantly improve the training effect and satisfaction,and provide reference for the development of relevant teaching and training.
