Purpose:
To assess the usability and feasibility of augmented-reality smart glasses during simulated pediatric bladder catheterization with real-time remote specialist guidance.
Methods:
Thirty-five critical-care graduate healthcare professionals simulated pediatric bladder catheterization on a manikin using Vuzix M400 glasses via telemedicine. After brief familiarization, participants completed a seven-item Likert (0-7) questionnaire covering ease of use, procedural understanding, confidence/efficiency, comfort, and global acceptance. We analyzed descriptive statistics, internal consistency (Cronbach's α), and item-domain coherence. A conceptual diagram and synthesis table complemented quantitative data.
Results:
Augmented-reality-guided training showed generally favorable usability perceptions. Median scores ranged 3.5-5, with strongest ratings for observation support, image quality, procedural understanding, and intention to recommend. Comfort and efficiency scored lower (median = 3.5), indicating more neutral perceptions. The instrument showed high internal consistency (α = 0.97), although this may reflect item redundancy, and item-domain alignment provided a descriptive representation of the conceptual model.
Conclusion:
These findings suggest that augmented-reality smart glasses are feasible and generally well accepted for simulated remotely guided training. Further controlled studies with objective performance measures are needed.
