More and more wearable devices are coming on the market intended to help people with their health and fitness goals. There will be medical devices that will adopt the system perspective of wearables and evolve to being tools that can predict upcoming health problems and enable people to head them off.
Combined with family medical history and genetic data, these future devices will help us transition from a system that predominantly treats injury and disease, to one that helps prevent it. The focus of medicine and healthcare is rapidly changing to emphasize prevention rather than just treatment. Those involved in medicine/healthcare would be wise to adapt their thinking to this new paradigm.
