Medical Cyber-Physical Systems: IoMT Applications and Challenges.

The Internet-of-Medical-Things (IoMT) is a network of connected medical devices, hardware infrastructure, and software platforms used to connect healthcare information technology. While the IoMT has expanded access to real-time health information, a side-effect has been inundating clinicians with excessive amounts of information - some of which is critical - but the vast majority is superfluous. This has led to clinician burnout, alarm fatigue, and skepticism when adopting new technologies. Leveraging the IoMT infrastructure, Medical Cyber-Physical Systems (MCPS) seek to address these issues by providing more actionable information, detecting device failures, and improving patient safety and treatment effectiveness. MCPS can provide an effective summary of patient state by fusing data from multiple physiological monitoring devices. Furthermore, MCPS can utilize patient physiology represented as a model to provide automatic closed-loop control of patient treatment, which does not require clinician intervention, under known safe conditions. The need to design such MCPS/IoMT systems that are safe, effective, trustworthy, and helpful to clinicians has presented numerous challenges. In this paper, we discuss the challenges in developing MCPS/IoMT, some of our work in addressing them, and several open research issues.
