Study: OR noise raises risk of surgical error

Editor's Note

Often exceeding federal safety limits, OR noise contributes significantly to communication breakdowns, heightened cognitive load, and increased surgical errors, according to a review of literature published September 17 in Cureus.

Identified noise sources include surgical instruments, alarms, and staff conversations, which can reach up to 120 decibels (dBA)—a level comparable to heavy traffic. These auditory challenges disrupt surgical teams and delay critical tasks, increasing stress and error rates among healthcare workers.

Recommended interventions  include strict noise control policies, using noise-reducing materials in OR design, and educating staff on the effects of noise. Structured communication protocols and continuous noise monitoring also can enhance safety and efficiency, researchers say. Additionally, surgeon leadership is critical to “balancing assertiveness and empathy” to promote teamwork, reduce noise-related distractions, and minimize risks to caregivers and patients.
