Multicenter, multidisciplinary user-centered design of a clinical decision-support and simulation system for massive...

Area of Science:

• Medical Informatics
• Human-Computer Interaction
• Emergency Medicine

Background:

• Managing critical bleeding with massive transfusion (MT) involves complex, time-sensitive tasks for multidisciplinary teams.
• High cognitive load and the need for situational awareness in rapidly changing scenarios are key challenges.
• Clinical decision support (CDS) tools have shown benefits in similar resuscitation settings.

Purpose of the Study:

• To design a computerized CDS tool for MT using a user-centered design (UCD) approach.
• To address the complexities of MT management, including cognitive load and situational awareness.
• To develop a prototype that supports multiple user roles and facilitates MT training.

Main Methods:

• A multicenter, multidisciplinary UCD study involving cognitive walkthroughs and user requirement analysis.
• Co-design and iterative prototyping of the CDS tool with end-users.
• Evaluation of the final prototype using qualitative assessment and the System Usability Scale (SUS).

Main Results:

• Development of a high-fidelity, web-based CDS prototype for MT through two UCD cycles.
• Evaluation with 15 participants in a simulated bleeding scenario yielded an average SUS score of 69.3 (above average).
• The prototype demonstrated a clear interface and facilitated easy blood product tracking.

Conclusions:

• A UCD process effectively addressed the complexities of developing a CDS for MT.
• The prototype CDS enhances distributive situational awareness and supports multiple roles in MT management.
• Further evaluation is underway to assess the prototype's impact on MT management efficacy and efficiency.
