Comparing Mixed Reality, Video-Based, and Instructor-Led Training in Nasogastric Tube Insertion: A Randomized Controlled Trial Assessing Learning Outcomes, Usability, and Student Experiences in Nursing Education

What this Trial Is About

This research aims to evaluate how first-year nursing students learn to insert a nasogastric tube (NGT), a common but potentially risky clinical procedure. The study compares three teaching methods: Mixed Reality (MR) glasses with virtual instructions, video-based learning, and traditional instructor-led training. It investigates which method improves learning outcomes, measures usability, and explores students' experiences with MR technology. Participants are randomly assigned to one of three groups receiving identical instructional content based on a standardized NGT insertion protocol. The MR group uses Meta Quest 3 glasses with an interactive application, the video group watches a procedure video recorded from the operator's viewpoint, and the instructor-led group attends classroom instruction with live demonstrations and supervised practice on a manikin. Each group completes training and assessments, with follow-up testing six months later to evaluate long-term skill retention. During the study, participants perform NGT insertion on a manikin and complete questionnaires including workload assessments, usability scales, and reflections on their experience. Researchers measure performance using a standardized NGT checklist immediately and six months after training. Data collection includes theory tests, user experience surveys, and qualitative reflections. The study ensures informed consent, anonymized data, and follows ethical standards under the Medical Research Council framework.
