Today’s health care system, in the United States and throughout the world, is still entering the 21st century. Costs remain high, there are great inefficiencies, and, for a large percentage of the population globally, access to care is inadequate. Our health care enterprises tend to focus on treating acute illness rather than improving and maintaining the health and wellness of populations. Today, “digital health” means advanced analytics based on multi-modal data; the “Health Care Internet of Things,” which uses sensors, apps, and remote monitoring to provide continuous clinical information; and data in the cloud that enables clinicians to access the information they need to care for patients in their home, their office, or 300 miles away, and to collaborate with specialists in another country.
