Cognitive Aid App Design and Speed During Critical Events

Sample size: 8 publication Evidence: moderate

Author Information

Author(s): Still Brady, Clebone Anna

Primary Institution: University of Chicago

Hypothesis

The design of an electronic pediatric critical event app will decrease the time to find critical information.

Conclusion

A well-designed cognitive aid mobile application led to faster information acquisition during critical events compared to a control design.

Supporting Evidence

  • Subjects found information more quickly using the experimental app compared to the control app.
  • The median time to find information was 6 seconds for the experimental app and 10.5 seconds for the control app.
  • The study involved a convenience sample of anesthesia providers.

Takeaway

This study shows that a better-designed app helps doctors find important information faster during emergencies.

Methodology

Data was collected from anesthesia providers using two app designs in a simulated environment, measuring the time taken to find information.

Limitations

The study was conducted in a low-fidelity simulation and may not reflect real-world conditions.

Participant Demographics

Participants included five faculty anesthesiologists, two residents, and one fellow, with a mean age of 36.
