Patient-focused healthcare, driven by COVID-19 experiences, has become a hallmark for providing healthcare services to patients across all modalities of care and in the home. The ability to capture real-time patient data, no matter the location, via remote patient monitoring, and to transmit that data to providers and organizations approved by the consumer/patient, will become a critical capability for all healthcare providers. Of all the remote patient monitoring product designs, wearable medical devices are emerging as the best positioned to support the evolving patient-focused healthcare environment.This book is for those who are evaluating, selecting, implementing, managing, or designing wearable devices to monitor the health of patients and consumers. This book will provide the knowledge to understand the issues that mitigate the risk of wearable technologies so people can deliver successful projects using these technologies. It will discuss their use in remote patient monitoring, the advantages and disadvantages of different types of physiological sensors, different wireless communication protocols, and different power sources. It will describe issues and solutions in cybersecurity and HIPAA compliance, as well as setting them up to be used in healthcare systems and by patients.
