Imagine a future in which clinicians, care teams, patients, and caregivers have convenient, secure access to comprehensive health information (health records, claims, cost, and data from medical devices). Technology can aid in preventing disease, identifying the need to adjust medications, and delivering interventions. Continuous monitoring can lead health care organisations to personalised therapies that address unmet medical needs sooner. And the “time to failure” can become shorter as R&D advancements, such as a continual real-world evidence feedback loop, will make it easier to identify what therapies will work more quickly in which patients. Instead of seeking care when sick, the focus can be on cost-effective prevention and keeping people healthy longer. One fundamental enabler of this vision is radically interoperable data. The future of health envisions timely and relevant health and other data flowing between consumers, today’s health care incumbents, and new entrants. This requires the cooperation of the entire industry, including hospitals, physicians, health plans, technology companies, medical device companies, pharma companies, and consumers.
