A tablet-based augmented reality system to reduce preoperative anxiety in pediatric patients: a quasi-experimental pilot study

This pilot study demonstrates the feasibility of integrating a tablet-based AR system into perioperative workflows. Preliminary findings also indicate that this approach may help reduce preoperative anxiety in this population. Given the pilot nature of the study, non-randomized allocation, and baseline imbalances between groups, validation in larger, well-controlled, randomized trials is required.
