As part of our study #SmartHealthSystems which examines the digital transformation of healthcare systems in 17 countries, we have visited five of these countries to take a closer look at what they have achieved. In each country, we have inquired about the political, cultural, technological and economic factors driving success as well the obstacles to a successful digitization strategy in healthcare. We will publish the findings of our cross-national study in full in November 2018. Until then, we will be highlighting thought-provoking insights and best practices from other countries here in our blog. Jakob Uffelmann, Director of Innovation at sundhed.dk, tells us how the Danish portal became a success story, how data protection is guaranteed, and what future services for citizens and patients are being developed.
