This is an especially exciting paper, as it is the first to come out of the OHDSI Asia-Pacific (APAC) Workgroup. The APAC team leads a bi-weekly community call, and each is recorded. Last week’s session included a presentation from Christian Reich about the FHIR-OMOP partnership. You can see that recording and get both the link and themes for upcoming calls at the APAC homepage.
