2020 OHDSI Global Symposium

The 2020 OHDSI Global Symposium brought together a global research community for 18 hours of open science, international collaboration and community fun on Oct. 19. The day included presentations from community members, panels that brought together leaders from a variety of major healthcare organizations, as well as network sessions, the annual collaborator showcase, and plenty more. Please check out this page for complete updates from the day, and follow the OHDSI Twitter and LinkedIn feeds for the #OHDSISocialShowcase, which will highlight all presentations from the 2020 Collaborator Showcase.

The four-day event also included five virtual tutorials on Oct. 18, and a two-day study-a-thon (Oct. 20-21) that focused on two cardiovascular clinical prediction models (CPM) routinely used in clinical practice: the Revised Cardiac Risk Index (RCRI) and the Pooled Cohort Equations. That collaborative effort set the foundation for multiple network studies on these important healthcare issues.

COVID-19 was a new infection inflicting enormous suffering with no known treatment and little known about its transmission. The scientific community roared into action, quickly generating evidence from observational data and beginning numerous trials. The editorial and peer-review process was overwhelmed, and the urgent need for evidence required rapid assessment of the studies’ rigor and importance. Highly publicized retractions and corrections contributed to a general feeling that a large proportion of the published work was substandard and misleading.

The OHDSI community strives to avoid substandard work by providing a public protocol before beginning research, reporting results only from multi-institution studies, verifying results with a full set of diagnostics, executing data quality checks, reporting data provenance, etc. Such rigor takes time, however, and given the current paradigm of celebrating being “first,” there remains little opportunity to provide reliable evidence after the journals have accepted early questionable results. Such undue focus on speed gives the unfortunate impression that once sufficient unreliable evidence has been published, reliable answers are no longer needed.


Panel: 2nd Annual Women of OHDSI Leadership Forum

Panelists: Vivian Lee (President of Health Platforms, Verily Life Sciences), Robyn Jones (Senior Medical Director, Women’s Health, Johnson & Johnson), Rear Admiral Deborah Hopson (Senior Vice President, Public Health Systems Innovation, MayaTech Corporation), Subha Madhavan (Chief Data Scientist, Associate Dean/Associate Professor of Oncology and Biomedical Informatics, Georgetown University)

Moderators: Ru-fong Cheng (Senior Medical Director, Women’s Health, Johnson & Johnson) and Maura Beaton (Women of OHDSI Workgroup Leader, Columbia University)

The Women of OHDSI Leadership Forum was one of the highlights of our 2019 Symposium, so we were thrilled to bring it back for our Global Symposium. Once again, some leading women in healthcare joined our leadership forum to discuss their careers, the field and provide mentorship to the many women (and men) in our community who are at varying stages on their own journey.


Collaborator Showcase

There were more than 100 presentations of OHDSI research and collaboration at this year’s Collaborator Showcase.
