# Wireless In-Ear Communication for Total Joint Arthroplasty: A Simulated Operating Room Evaluation

## TL;DR

This study shows that wireless in-ear communication devices improve communication in simulated orthopedic surgeries compared to traditional loud voice methods.

## Contribution

The novel contribution is demonstrating the effectiveness of wireless in-ear devices in orthopedic surgery simulations for better communication.

## Key findings

- In-ear devices improved phrase identification (78.6% vs 44%) and clarity (8/10 vs 4/10).
- Participants rated in-ear devices higher in effectiveness (7.9/10 vs 4.9/10) and usability.
- Sound levels were comparable between in-ear and traditional methods.

## Abstract

Effective communication is vital for patient safety, yet failures are common, often due to outdated methods. This study aimed to assess whether in-ear communication devices improve communication in orthopedic surgery simulations compared to traditional loud voice methods. Fifteen participants underwent simulations using both in-ear wireless devices and standard communication. Results showed significant improvements with in-ear devices in correctly identifying phrases (78.6% vs 44%), effectiveness (7.9/10 vs 4.9/10), and clarity (8/10 vs 4/10), all P < .001. Participants also favored in-ear devices in usability assessments. Sound levels recorded were comparable between groups. In conclusion, in-ear communication is safe and effective in orthopedic settings, potentially enhancing efficiency and safety. These devices can mitigate loud noises, benefiting surgeon well-being and patient outcomes.
