Operating room errors stem from fragmented device ecosystems where individual tool usability fails to account for environmental constraints like sterile barriers, cable management, and team communication distance. This human factors research insight is drawn from a 2020 study published in Applied Ergonomics. Using Contextual inquiry and qualitative thematic analysis with 21 staff members (surgeons, nurses, anesthesiologists), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Shift focus from individual device screens to the 'system of systems' by minimizing physical footprint and ensuring visual feedback is legible from at least 2 meters away.

Key Findings
Device failures are rarely about single-button design and primarily involve poor physical integration with other equipment, cable clutter hindering movement, and interfaces that do not account for the distance between the operator and the screen.
Application
Design takeaway
Shift focus from individual device screens to the 'system of systems' by minimizing physical footprint and ensuring visual feedback is legible from at least 2 meters away.
How to apply
Implement high-contrast, simplified UI that remains legible through protective plastic sheeting and design cable connectors that are identifiable by touch to prevent line-of-sight dependency.
Method & Evidence
Strengths & Limitations
Limitations
Findings are based on a single specialty (gynecology) and may not generalize to all surgical disciplines; guidelines require further empirical validation in varied clinical settings.
Design Principles
"Ecosystem-Centric Ergonomics"
Designers often treat surgical tools as isolated systems, ignoring that surgeons and nurses must juggle physical movement and coordination under high stress. When devices require precise interaction in a chaotic, multi-person environment, it increases the risk of accidental activation or delayed response during critical operative moments.
What This Means for Your Design
