The future of healthcare is proactive, marking a shift in focus from treating illnesses to preventing them. Medical self-monitoring is a booming trend and the networks that connect patients to machines to practitioners are increasingly complex, enabling multidirectional flows of information. Patients are empowered to monitor and manage their health. Health portals, communities, platforms and devices themselves enable them to take steps to prevent a number of conditions instead of relying completely on medical professionals to treat and cure them.
