Doctoral Research: A Human-Centered Design Approach to Prototyping a System to Support Delay Awareness in Trauma Resuscitation


Design, implement, and evaluate an information system to unobstrusively alert the trauma resuscitation team of delays and errors

Evaluation Methodology

Remote near-live simulations to evaluate the ability of the prototype to aid clinicians to detect delays

User Research Methods

Semi-structured Interviews and Card Sorting Workshops to learn common delay types and user design requirements

User-research Findings

  • Common Delays include establishing vascular access and obtaining vitals

  • Different role types experience delays differently

Design Methods

Iterative sketching methods followed by surveys to receive user feedback

Design Requirements

Visual and non-intrusive alerts

  • Displays that give a high-level of information.

  • Multi-modal system to increase awareness for all team members

Evaluation Findings

  • Clinicians were more likely to detect delays in the scenarios with the prototype alert system than in the control scenarios

    •  Participants voiced awareness of delays in 86% (13 out of 15) of instances in the scenarios with the prototype alert system.

    • In the control scenarios, participants voiced awareness of delays in just 53% (8 out of 15) of instances.

  • ​Participants in the control scenarios took longer to respond to delays than the participants in the experimental scenarios.

    • The median response time to a delay was 23 seconds in the experimental scenarios and 107 seconds in the control scenarios

  • 8/10 participants responded positively to the prototype, 2 participants were neutral
