Overview of a User-Centered, Mixed-Methods Process for Designing Interconnected and Focused Mobile Applications on...

Area of Science:

• Digital health interventions
• Human-computer interaction
• Medical simulation

Background:

• Pediatric cardiopulmonary resuscitation (CPR) adherence to guidelines is challenging due to cognitive overload and communication issues.
• Existing digital aids often lack integration or real-time adaptability for complex resuscitation scenarios.
• Stressful environments in pediatric resuscitation degrade team coordination and information flow.

Purpose of the Study:

• To design and evaluate InterFACE, an integrated, augmented reality (AR)-enabled digital health system.
• To enhance real-time adherence to Pediatric Advanced Life Support (PALS) guidelines.
• To improve team coordination during pediatric resuscitation events.

Main Methods:

• User-centered design with persona development and spatial analysis.
• Delphi method with experts to identify critical information elements.
• Simulation-based evaluations of AR head-mounted displays, team screens, and tablet applications.

Main Results:

• Consensus reached on 20 core information elements for display across system components.
• High usability and acceptance demonstrated for all InterFACE components (TeamScreen, Guiding Pad, AR HMDs).
• AR HMDs received excellent usability scores, with high task completion rates for the Guiding Pad and TeamScreen.

Conclusions:

• InterFACE, an integrated AR system, shows significant potential for improving PALS adherence and team coordination.
• The system demonstrated strong usability and acceptance in simulated pediatric resuscitations.
• Further research is needed for clinical effectiveness, real-world integration, and AI-driven decision support.
