Intervention Fidelity
HMD
Five nursing staff members at the preanesthetics assessment clinic received 30 minutes of training on how to operate the HMD console. The training included instructions on setting up the devices, adjusting the interpupillary distance on the HMD consoles, troubleshooting potential issues, and separating participants into control and intervention groups. A standardized procedure for implementing the VR-based intervention was developed to ensure the nurses’ adherence to the study protocol.
