What this research studies

You may have the operating room audio and video recorded so researchers can map when and how speech gets interrupted during surgery. They will interview surgical team members and use human factors methods and proven interventions from other industries to find what causes communication breakdowns. The team will create detailed timelines of communication interference events and design changes to reduce those interruptions. Those changes will then be tried in real ORs to see whether communication and safety improve.

Who could benefit from this research

Good fit: Ideal candidates are people scheduled for operations at participating hospitals who agree to audio/video recording and brief follow-up, which may include people having abdominal procedures such as cesarean delivery.

Not a fit: Patients who have emergency surgeries, who decline recording or consent, or whose procedures occur outside the study hospitals are unlikely to directly participate or receive immediate benefit.

Why it matters

Potential benefit: If successful, this work could lower communication-related surgical errors and improve safety and outcomes for people having operations.

How similar studies have performed: Efforts to reduce hospital noise and apply human factors solutions have improved safety in other settings, but applying these methods specifically to speech interference in the OR is relatively new.
