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