Summary
Augmented reality (AR) significantly improved patient, caregiver, and provider satisfaction during pediatric anesthesia induction. This immersive technology reduced anxiety and enhanced the overall experience for children undergoing medical procedures.
Area of Science:
- Pediatric Anesthesiology
- Human-Computer Interaction
- Medical Technology
Background:
- Anesthesia induction in children is often a distressing experience.
- Augmented reality (AR) presents a potential tool to mitigate this distress by engaging patients.
- Investigating AR's impact on patient, caregiver, and provider perspectives is crucial for adoption.
Purpose of the Study:
- To evaluate the satisfaction and usability of an augmented reality (AR) intervention during pediatric anesthesia induction.
- To assess the impact of AR on patient anxiety levels and overall experience.
- To gather perspectives from patients, caregivers, and healthcare providers on AR's effectiveness.
Main Methods:
- A pilot study involving 24 pediatric patients (aged 10-19) undergoing anesthesia induction with an AR intervention.
- Utilized pre- and post-procedural surveys including the anxiety thermometer visual analog scale (VAS) and the Gold & Rizzo Immersion and Presence (GRIP) inventory.
- Analyzed qualitative data and conducted univariate analyses to determine primary outcomes related to usability and satisfaction.
Main Results:
- High satisfaction reported by patients, caregivers, and healthcare providers with the AR intervention.
- 88% of providers indicated AR aided patients during induction; caregivers and patients reported high ratings for AR's anxiety-reducing and helpful effects.
- VAS ratings showed no significant increase in patient anxiety (p=0.102), and the GRIP inventory indicated moderate to high satisfaction, immersion, and functionality.
Conclusions:
- Augmented reality (AR) is a highly satisfactory, usable, and effective tool for pediatric anesthesia induction.
- The AR intervention demonstrated significant potential in reducing patient distress and enhancing the experience for all stakeholders.
- AR's immersive and engaging nature supports its integration into clinical practice for pediatric procedural care.
