Dear colleagues,

We regret to inform you that the OHDSI European Symposium 2020 and tutorials on 27-29 March 2020 have been cancelled.

This very difficult decision has been taken after receiving a growing number of cancellations due to the COVID-19 outbreak. The safety of our delegates is our priority and, given the uncertainty around the spread of the disease and how institutional and country travel regulations will adapt in the coming three weeks, it has been decided not to go ahead with the symposium on the 27th or the tutorials on the 28th and 29th of March 2020.  

We are really sorry to cancel what we were convinced was due to be one of the most interesting events on real world health data research of the year. We had reached a total of 205 registrations, had 10 contributing sponsors including EHDEN partners and certified SMEs (see the full list below), and a total of 44 abstract submissions. We will notify all the authors of submitted abstracts separately about how to share their results virtually in poster format that will be uploaded to both the European and U.S. OHDSI web sites, as well as shared on both the OHDSI LinkedIn (1150+ followers) and Twitter (1050+ followers) feeds. We want to share all of the great research happening within our community. Craig Sachson, director of communications for OHDSI, will reach out to all of you this week with details of how to submit your poster, abstract and any other materials so that your research will be shared with the OHDSI community and beyond.

We hope those who planned to attend the OHDSI Europe Symposium will use this time to consider how they can work together within the OHDSI community to collaboratively generate the evidence that promotes better health decisions and better care. Do note that the 2020 US OHDSI Symposium is scheduled for 18-21 October, Bethesda North Marriott Hotel & Conference Center.

The tutorial registrations will be reimbursed in full automatically with no actions required from the delegates. If you have any further questions, please let us know at This email address is being protected from spambots. You need JavaScript enabled to view it..

Kind regards,


The OHDSI Europe Symposium Organising Committee
