A human factors subsystems approach to trauma care

Area of Science:

• Medical Systems Engineering
• Human Factors Engineering in Healthcare
• Trauma Care Process Optimization

Background:

• Physician-centered systems design is crucial for reducing medical errors and improving reliability.
• Existing trauma care processes face challenges in coordination, communication, and equipment management.

Purpose of the Study:

• To apply human factors engineering principles to redesign the trauma care process.
• To address identified impediments in care coordination, communication, and equipment use.

Main Methods:

• An interrupted time series design was employed with historically controlled data.
• Direct observation of patients in a level I trauma center before and after interventions.
• Iterative cycles of intervention development involving trauma team engagement.

Main Results:

• Interventions included headsets, equipment storage, medication packs, a whiteboard, prebriefing, and teamwork training.
• Flow disruptions increased with computed tomography (CT) and operating room visits, but the intervention mitigated some effects.
• Total treatment time in the emergency department was reduced by 20-30 minutes; length of stay decreased for high-risk patients.

Conclusions:

• Implementing complex interventions based on human factors engineering and systems analysis improved trauma care.
• The study demonstrated reduced flow disruptions, treatment times, and length of stay.
• This approach highlights the effectiveness of optimizing trauma care systems for better patient outcomes.
