This qualitative overview of the Open Health Data initiatives is meant to showcase the importance of open health data, social as well as economic impacts across US, UK and a select set of Western European countries. This overview is not meant to be a comprehensive report on all the global initiatives, funding models and tracking of open health data. There are tremendous efforts across the globe to change our global healthcare system and we believe that open health data is one of the keys to bridge the gap between digital citizens & governments. Also, please note that if your country, initiative or product was not mentioned, it is in no way meant to diminish the impact of the efforts. Please feel free to share, discuss and contribute to the list of ongoing efforts and initiatives on one of our global communities or on openhealthdata.org.
