Japanese Regulatory Considerations for Interoperability of Medical Devices

With the rapid technological innovations of the Internet of Things (IoT), the situation surrounding medical devices and medical systems has been changing. Interoperable medical devices—medical devices capable of interoperating in a clinically significant way with other medical devices—have been developed, and interoperable medical systems consisting of two or more interconnected interoperable medical devices are being used in clinical settings. However, general points that need to be considered to ensure safe and effective interoperability have yet to be fully established in Japan. A research project (FY2019–FY2021) to discuss issues associated with ensuring safe and effective interoperability was commissioned by the Japan Agency for Medical Research and Development. A pivotal aspect identified in that project is how to manage the sharing of data and information among interoperable medical devices from different manufacturers. Characteristics and timestamps of data and information need to be exchanged between interoperable medical devices. Risks associated with interoperable devices should be managed in a manner appropriate to the characteristics and the intended use of the interoperable medical devices. In this review, we summarize the aspects of data and information that this study group judged were important to consider for ensuring safety and effective interoperability.
