Supporting Emergency Medical Care Teams with an Integrated Status Display Providing Real-Time Access to Medical Best...

Area of Science:

• Medical informatics
• Human-computer interaction
• Healthcare systems engineering

Background:

• Medical staff work is safety-critical, often under severe time constraints.
• High cognitive load in stressful environments challenges adherence to healthcare best practice workflows.
• Effective cognitive support is needed for medical teams.

Purpose of the Study:

• To develop a human-centered system for cognitive support in medical teams.
• To reduce medical teams' cognitive load during critical events.
• To foster real-time adherence to medical best practices.

Main Methods:

• Studied and modeled medical team responsibilities and interactions during cardiac arrest resuscitation.
• Decomposed resuscitation tasks into distinct cognitive tasks requiring support.
• Developed and evaluated a medical Best Practice Guidance (BPG) system using a patient simulator with physicians and nurses.

Main Results:

• The developed BPG system was evaluated with healthcare professionals.
• Evaluation indicated a reduction in cognitive load for medical teams.
• Enhanced adherence to medical best practices was observed.

Conclusions:

• The Best Practice Guidance (BPG) system effectively reduces cognitive load.
• The system supports medical teams in adhering to best practices during critical events.
• Human-centered system design can improve safety and efficiency in healthcare.
