For decades, innovators have been holding a candle for the potential of Big Data to one day revolutionise health care. Entrepreneurs have developed ways for people to track their own biological metrics, and for companies to use advances like artificial intelligence to provide more targeted care. Are we finally at the point where data can lead to tangible changes in health care? Or is still an unfulfilled promise?
Companies like IBM Watson Health and Flatiron Health are taking data from electronic health records, cleaning it up, and using that data to identify potential interventions and cost-saving opportunities.
