Speech Communication Interference in the Operating Room: Frequency, Impact, and Causes

Speech communication interference events are common in operating rooms, with significant implications for patient safety. A study of 40 surgeries revealed a mean of 2.58 speech interference events per surgery, primarily involving attending physicians, circulating nurses, residents, and scrub techs. Most events occurred during patient-related tasks, with 17.5% happening at critical moments. Interestingly, 27.2% of events were not acknowledged or repeated, resulting in lost messages. Additionally, 97% of events caused delays, lasting an average of 5 seconds. Reorganizing workflow, tasks, and communication behaviors can enhance surgical safety and efficiency.
