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

Area of Science:

• Surgical Simulation
• Medical Device Technology
• Patient Safety

Background:

• Effective communication is critical in healthcare, particularly in high-stakes environments like orthopedic surgery.
• Traditional communication methods, such as loud voice, are often inadequate and prone to failure, potentially compromising patient safety.
• The operating room environment can be noisy, further hindering clear communication.

Purpose of the Study:

• To evaluate the efficacy of in-ear wireless communication devices in improving communication accuracy and effectiveness during orthopedic surgery simulations.
• To compare the performance of in-ear devices against traditional loud voice communication methods.
• To assess user preference and usability of in-ear communication devices in a simulated surgical setting.

Main Methods:

• Fifteen participants engaged in simulated orthopedic surgery scenarios.
• Communication was assessed using two methods: in-ear wireless devices and standard loud voice.
• Key metrics included phrase identification accuracy, perceived effectiveness, clarity ratings, and device usability.

Main Results:

• In-ear devices demonstrated significantly higher phrase identification rates (78.6% vs. 44%, P < .001).
• Participants reported greater effectiveness (7.9/10 vs. 4.9/10) and clarity (8/10 vs. 4/10) with in-ear devices.
• Usability assessments favored the in-ear communication systems, with comparable sound levels between methods.

Conclusions:

• In-ear communication devices represent a safe and effective advancement for orthopedic surgical settings.
• These devices have the potential to enhance surgical efficiency and patient safety by overcoming communication barriers.
• Implementing in-ear technology can mitigate the impact of high-noise environments, contributing to improved surgeon well-being and patient outcomes.
