Big data & digital health

Measuring is knowing. A lot of data is available on this. But it is often to fragmented. What used to be kept on paper, is now systematically digitized so that every doctor, nurse but also those involved in primary care have access to the useful and necessary data from the patient file. How far are we going to share data? What is needed to better coordinate data? And how do we eventually get the right insights from that mountain of collected data?
