基于“互联网+”的增强现实与混合现实技术在骨科住院医师规范化培训中的应用

  目的  分析基于“互联网+”的增强现实(augmented reality，AR)与混合现实(mixed reality，MR)技术在骨科住院医师规范化培训中的应用效果。  方法  以蚌埠医学院第一附属医院基于“互联网+”的AR/MR技术的骨科教学培训实施时间(2019年3月)为界限，将实施前(2018年3月—2019年2月)入组的30名骨科住院医师纳为对照组，采用常规骨科培训方法；将实施后(2019年4月—2020年5月)入组的32名住院医师纳为观察组，采用新型培训方法。分别统计2组培训结束时的理论成绩及操作成绩改善情况，记录带教老师对本次培训的自我评价；比较2组住院医师的培训满意度。  结果  2组培训前的理论及操作考核成绩比较差异无统计学意义(P>0.05)，培训结束时，观察组的理论成绩改善率(26.74±5.12)%]和操作成绩改善率(16.59±2.14)%]显著高于对照组(18.89±4.06)%和(7.05±1.02)%，均P < 0.05]；AR/MR技术带教模式下带教老师的统筹安排及管理能力、多媒体教材应用能力及教学意识评分显著高于常规骨科带教模式(P < 0.05)；培训结束时，观察组住院医师的培训满意度评分显著高于对照组，差异有统计学意义(均P < 0.05)。  结论  基于“互联网+”的AR/MR技术应用于骨科住院医师规范化培训，可有效提高骨科带教老师的临床教学能力，改善住院医师的培训满意度和考核成绩，具有良好的推广意义。 

Application of augmented reality technology and mixed reality technology based on "Internet Plus" in the standardised training of orthopaedic doctors

  Objective  To analyse the application effects of augmented reality (AR) technology and mixed reality (MR) technology based on "Internet Plus" in the standardised training of orthopaedic doctors.  Methods  Taking the implementation time (March 2019) of orthopaedics teaching and training of AR/MR based on "Internet Plus" in the First Affiliated Hospital of Bengbu Medical College as the dividing line, 30 resident doctors in the Department of Orthopaedics who were enrolled before the implementation (from March 2018 to February 2019) were included in the control group and received conventional orthopaedics training, and 32 resident doctors enrolled after the implementation (between April 2019 and May 2020) were enrolled in the observation group and given the new training method. The improvement status of theoretical and operational results of the two groups was statistically analysed at the end of the training, and the self-evaluation of clinical teachers on the training was recorded. The training satisfaction of the two groups of resident doctors was compared.  Results  No statistical differences were observed in the theoretical and operational results between the two groups before training (P>0.05). At the end of the training, the improvement rates of theoretical (26.74±5.12) %] and operational (16.59±2.14) %] results in the observation group were significantly higher than those in the control group (18.89±4.06) % and (7.05±1.02) %, all P < 0.05]. The scores of overall arrangement and management ability, application ability of multimedia teaching materials and teaching awareness of clinical teachers under the AR/MR teaching model were significantly higher than those of conventional orthopaedics teaching model (P < 0.05). At the end of the training, the training satisfaction scores of resident doctors were significantly higher in the observation group than in the control group (all P < 0.05).  Conclusion  The application of AR/MR based on "Internet Plus" in the standardised training of resident doctors in the Department of Orthopaedics can effectively improve the clinical teaching ability of orthopaedics teachers and improve the training satisfaction and assessment results of resident doctors, with good promotion significance.
