UnlabelledFor more than a century, Mayo Clinic has used various communication strategies to optimize the efficiency of physicians. Anesthesiology has used colored wooden tabs, colored lights, and, most recently, a distributed video paging system (VPS) that was near the end of its useful life. A computer-based anesthesiology paging system (CAPS) was developed to replace the VPS. The CAPS uses a hands-off paradigm with ubiquitous displays to inform the practice where personnel are needed. The system consists of a dedicated Ethernet network connecting redundant central servers, terminal servers, programmable keypads, and light-emitting diode displays. Commercially available hardware and software tools minimized development and maintenance costs. The CAPS was installed in >200 anesthetizing and support locations. Downtime for the CAPS averaged 0.144 min/day, as compared with 24.2 min/day for the VPS. During installation, neither system was available and the department used beepers for communications. With a beeper, the median response time of an anesthesiologist to a page from a beeper was 2.78 min, and with the CAPS 1.57 min; this difference was statistically significant (P = 0.021, t(67) = 2.36). We conclude that the CAPS is a reliable and efficient paging system that may contribute to the efficiency of the practice.ImplicationsMayo Clinic installed a computer-based anesthesiology paging system (CAPS) to inform operating suite personnel when assistance is needed in procedure and recovery areas. The CAPS is more reliable than the system it replaced. Anesthesiologists arrive at a patient's bedside faster when they are paged with the CAPS than with a beeper.
