Hands-free communication devices (HFCDs) are an information and communication technology comprised of wearable "badges" and server-based software. The technology is distinguishable by three traits: 1. It utilizes voice-over-Internet protocol (VoIP) and wireless local area networks (WLANs), 2. The communication devices are wearable, and 3. The technology possesses voice control capability. HFCDs are increasingly used in clinical care settings, particularly among nursing staff. Quantitative studies and surveys report that clinicians who use HFCDs experience faster communication times but also have concerns about reliability and patient confidentiality.
