NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Educational Effects of and Satisfaction with Mixed-Reality-Based Major Trauma Care Simulator: A Preliminary Evaluation
ABSTRACT
Background:
Mixed reality (MR) is a hybrid system that projects virtual elements into reality. MR technology has the advantage of providing immersive learning using various real-world tools. However, studies on educational programs using MR are scarce.
Objective:
This study aimed to investigate the educational effects of and satisfaction with an MR-based trauma decision-making simulator.
Methods:
A total 40 of trainees self-selected to participate in this experiment. All participants participated in the MR trauma simulator for approximately 30 minutes and conducted voluntary learning without any external help. Declarative knowledge, measured using 20 multiple-choice questions, was assessed before and after MR trauma training. To confirm the educational effect, test scores before and after MR trauma training were compared using a paired t-test. Student satisfaction after training was measured using a ten-item questionnaire rated on a five-point Likert scale.
Results:
A pretest-posttest comparison yielded a significant increase in declarative knowledge. The percentage of correct answers to multiple choice questions increased (from a mean of 42.3, SD 12.4 to 54.8, SD 13) after the MR-based trauma assessment and treatment training (P < 0.001). Of the participants, 79.45% were satisfied with the overall experience of using the MR simulator.
Conclusions:
This study demonstrated a meaningful educational effect of the MR-based trauma training system even after a short training time.
