  Improving the health of the nation's population and increasing the
capabilities of the US healthcare system to support diagnosis, treatment, and
prevention of disease is a critical national and societal priority. In the past
decade, tremendous advances in expanding computing capabilities--sensors, data
analytics, networks, advanced imaging, and cyber-physical systems--have, and
will continue to, enhance healthcare and health research, with resulting
improvements in health and wellness. However, the cost and complexity of
healthcare continues to rise alongside the impact of poor health on
productivity and quality of life. What is lacking are transformative
capabilities that address significant health and healthcare trends: the growing
demands and costs of chronic disease, the greater responsibility placed on
patients and informal caregivers, and the increasing complexity of health
challenges in the US, including mental health, that are deeply rooted in a
person's social and environmental context.
