WEEKLY COMMUNITY CALL MEETING
OHDSI collaborators worldwide are exploring how large language models (LLMs) can support the evidence generation process. Several projects were highlighted at the Europe Symposium, and more will be featured at the upcoming Global Symposium this October. To build awareness and foster collaboration, a group of collaborators will join our Aug. 26 (11 am ET) community call to share brief overviews of their work with LLMs.
Everybody is invited. If you do not have a calendar invite, please use this link to join the meeting. All recordings from these weekly calls are available within our Teams environment and will be posted on both our YouTube page and our OHDSI.org Community Calls page.

OHDSI UPDATES
Nominations for the 2025 Titan Awards are now open. The Titan Awards recognize OHDSI collaborators (or collaborating institutions) for their contributions towards OHDSI’s mission; they are nominated and voted upon by members of the community; please share your nominations before the Sept. 9 (8 pm ET) deadline.
• The agenda for the 2025 Global Symposium is now available. Specific information, including presenters, talk/poster/demo titles, and more will be added when available.
• The CDM Survey Sub-Workgroup is relaunching the Landscape Assessment of Survey Data and the OMOP CDM, https://forms.gle/f18ufspAFT3jSYrk6 for the month of August in preparation for our workshop at the Global Symposium. If you have mapped survey data (in progress or complete) or plan to map survey data to the OMOP CDM and have not previously filled out the assessment or met with the workgroup we need you to complete the assessment so we can determine the state of surveys in OMOP and where appropriate share resources with the OHDSI community. If you have any questions or problems with access, email me at [email protected]. More information about the CDM Survey Sub-Workgroup can be found here Home · OHDSI/CdmSurveySubWg Wiki · GitHub.
• OHDSI is now on Bluesky! You can now get updates on all community activities and see all global research through the #OHDSISocialShowcase on Bluesky.
