Abstract:

Wireless communication systems that include LANs and voice communication have been installed in most Japanese hospitals. However, various problems have been discovered. According to a survey by the Japanese Government, many Japanese hospitals have experienced problems that are caused by signal propagation when using wireless communication. If a communication breakdown occurs, current information on patients such as sudden changes in condition or the warning alarms of medical devices may not reach the relevant staff. This can result in a harmful delay in the detection of a sudden change in a patient’s condition or in making an erroneous decision. Patient deaths caused by abnormalities in the transmission or reception of signals from the nurse call terminal have been reported. In this paper, we describe problems related to building structure and electromagnetic fields emitted from equipment and make suggestions for correcting them. We also introduce and discuss remedies to the problems that have been proposed in two sets of Japanese guidelines.
