Creating a Culture of Safety by Reducing Noise Levels in the OR

We implemented a quality improvement project to reduce noise levels in the OR in response to complaints from the anesthesia staff members at two community hospitals. Excessive noise has been shown to increase staff member stress, fatigue, distraction, and ineffective communication, which can lead to medical errors. We measured noise levels during anesthesia induction and emergence for 118 different surgical procedures and compared noise levels before and after the improvement project intervention. Staff member education and noise reduction strategies, which included signage, prominent noise meters, and specific suggestions to staff members, helped to significantly reduce the noise level during the anesthetic induction and emergence phases of OR procedures.
