Emergency departments (EDs) have unique operational requirements within hospitals. They have strong availability demands, are staffed by rotating personnel, and must provide services as quickly as possible. Modern EDs are also heavily computerized, and as such cybersecurity practices play a key role in meeting the expected operational standards. To better understand the cybersecurity challenges in EDs, we conducted a survey asking 347 ED personnel across Canada about their cybersecurity practices. The survey collected information relating to authentication and password management, use of personal devices for handling patient data, Internet connectivity on personal and hospital systems, and institutional security policies. Our results show that across multiple hospitals, deployed computer security systems fail to integrate with the requirements of staff and patients, leading to interruptions and inefficiencies.
