Randomized controlled trial evaluating mixed reality technology for training scrub nurses in anterior cervical spine
1Department of Operating Room, The Affiliated Suqian Hospital of Xuzhou Medical University, Suqian, China.
Background:
Mastery of instrument sequencing and spatial anatomy is crucial for scrub nurses in anterior cervical spine surgery (ACSS), yet conventional training often fails to provide immersive, three-dimensional practice.
Aim:
This randomized controlled trial evaluated a novel Mixed Reality (MR) training module against standard training for ACSS scrub nurse education.
Methods:
Sixty nurses were randomly assigned to an MR training group (n = 30) or a traditional training group (n = 30). The intervention group completed a structured MR curriculum using Microsoft HoloLens 2, featuring interactive 3D anatomy, virtual instrument handling, and emergency scenario simulation. The control group received standard lectures and video-based instruction. Primary outcomes were scores on theoretical knowledge, practical performance, and emergency response assessments. Secondary outcomes included cognitive load (NASA-TLX) and training satisfaction.
Results:
The MR group achieved significantly higher post-training scores in theoretical knowledge (92.47 vs. 86.33, p < 0.001), practical performance (94.50 vs. 88.97, p < 0.001), and emergency response (91.73 vs. 85.40, p < 0.001). Participants in the MR group also reported a significantly lower overall cognitive load (NASA-TLX total: 28.60 vs. 36.43, p < 0.001) and markedly higher satisfaction across all measured domains (p < 0.001).
Conclusion:
Immersive MR training is more effective than traditional methods in developing essential knowledge, skills, and situational preparedness for ACSS. It facilitates learning by reducing cognitive burden and increasing engagement, presenting a valuable tool for advancing surgical nursing education.
