OHDSI APAC - Our Asia-Pacific Community

OHDSI is a global, multi-stakeholder, interdisciplinary and open-science network that collaborates to bring out the value of health data through large-scale analytics. Our Asia-Pacific (APAC) community comprises six regional chapters (Australia, China, Japan, Singapore, South Korea, Taiwan) and has led important OHDSI initiatives around the world.

OHDSI APAC Community in Teams
The APAC community has its own group in the OHDSI MS Teams environment to promote greater collaboration on our collaborative efforts. First, request access to our MS Teams Environment, then request access to our OHDSI APAC workgroup.

APAC Bi-weekly Community Call
Everybody is invited to the bi-weekly OHDSI APAC community call, which takes place every other Thursday at 12 pm Korea time. These calls are meant to provide updates, share research presentations, collaborate on topics of shared interest, and plenty more. The upcoming schedule is available to the right.

Use this link to get to the bi-weekly meeting.

2022 APAC Studies
In 2021 APAC Symposium, the four studies below were selected by the community to work together in 2022.

Study documents and meeting recordings are saved under each study channel in OHDSI APAC Teams.

Study liaisons from each chapter are working closely with the study owners, and we appreciate all the help and support.

APAC Study Liaisons: Meet The Team

Past APAC Events
