From app doctors to big data: five ways tech will shape healthcare

Technology presents huge opportunities and challenges for our health and care system. Shipments of the activity tracking wearable Fitbit are up 25.4% this year, signalling more and more of us want insights into our exercise, eating, weight and sleeping patterns. As we begin to generate our own health data, our relationship with our bodies will change, and the way we understand and seek healthcare will be transformed. "Some of my patients will share outputs from their wearable ... when it comes to their yearly reviews. But this is the exception, rather than the rule at present," says Dr Junaid Bajwa, director of healthcare services, Merck (MSD).
