Background:
During rapid-sequence intubation, nurses are pivotal to patient safety, yet undergraduate curricula rarely include structured intubation nursing. Mixed reality (MR) simulation offers an immersive, clinically realistic environment that may address these gaps.
Aim:
To evaluate whether MR-based intubation nursing (MRIN) simulation improves nursing students' competency.
Design:
Parallel, triple-blinded, two-arm randomized controlled trial.
Methods:
Ninety-two nursing students were randomized to the experimental group (EG; n = 46) or control group (CG; n = 46). After one pre-intervention withdrawal (scheduling conflict), 45 experimental and 46 control participants completed the study.
Results:
The EG showed significantly higher intubation-nursing performance (U = 1707.00, p < .001; effect size [ES] = 0.65). Satisfaction was higher in EG (U = 1282.0, p = .044; ES = 0.24). Knowledge increased in both EG (Z = 5.842, p < .001) and CG (Z = 5.924, p < .001). Readiness for practice increased in both groups, with a greater median change in EG (U = 1285.5, p = .046; ES = 0.24). Within-group improvement in learning self-efficacy was statistically significant in the EG (Z = 2.38, p = .017).
Conclusions:
The MRIN program enhanced nursing students' performance and practice readiness compared with conventional simulation. However, because the EG received additional contact time, the between-group ES may have been overestimated, and the independent contribution of MR technology beyond additional practice time has yet to be established.
