Evaluation of a Hands-free Wireless Communication Device in the Perioperative Environment

The objective of this study was to evaluate the efficiency and reliability of a hands-free voice over Internet protocol (VOIP) communication system in the perioperative environment. Two surveys were administered to anesthesiologists and operating room (OR) nurses working at an academic medical center. Providers were queried by alphanumeric pages or VOIP queries during OR work shifts to measure communication response times. Providers, responding to the query, were asked to verbally complete a system performance survey to capture information regarding their workload and work environment at the time of the query. A user feedback survey was independently administered in writing to a convenience sample of OR providers to obtain information regarding provider communication preferences, concerns, and recommendations. OR providers responded to communication queries four times faster when using VOIP compared to alphanumeric pagers. Providers found VOIP to be much less reliable than conventional pager-telephone systems. Dead spots in the 802.11b network and errors in speaker recognition were frequently cited as sources of system failures. Providers also expressed concern in maintaining confidentiality of patient data or other clinical data communicated using this system. The results of this study suggest that VOIP is still a developing technology but one that is currently viable in the clinical setting. The technology can be used efficiently and securely in health care if users are given the proper training its functions and capabilities.
