Are gestures worth a thousand words? Verbal and nonverbal communication during robot-assisted surgery.

Communication breakdowns in the operating room (OR) have been linked to errors during surgery. Robot-assisted surgery (RAS), a new surgical technology, can lead to new challenges in communication owing to the remote location of the surgeon away from the patient and bedside assistants. Nevertheless, few studies have studied communication strategies during RAS. In this study, 11 robot-assisted radical prostatectomies were recorded and the interaction events between the surgeon and two bedside surgical team members were categorized by modality (verbal/nonverbal), topic, and pair (sender and receiver). Both verbal and nonverbal modalities were used by all pairs. The percentage of nonverbal interactions differed significantly by pair: 66% for the Surgeon-Physician Assistant, 50% for the Physician Assistant-Scrub Nurse, and 25% for the Surgeon-Scrub Nurse, indicating different communication strategies across pairs. In addition, there was a significant dependence between topic and the percentages of verbal and nonverbal events for all pairs. Strategies to improve team communication during RAS should take into account the use of verbal and nonverbal communication means and the variation in interaction strategies based on the topic of communication.
