Weekly OHDSI Digest – February 19, 2024


Please join our next community call on Tuesday, Feb. 20 (11 am ET) for our third set of updates from both our OHDSI workgroups and the Phenotype Phebruary leadership team. Workgroups will share their 2024 Objectives and Key Results (OKRs), and then we will hear about the third week of work in Phenotype Phebruary, with an emphasis on Week 3 focused phenotype, major depressive disorder.

The workgroups that we will hear from on Tuesday are Themis, Healthcare Systems, Generative AI and Analytics in Healthcare (GAIA), NLP, Oncology, Vaccine Vocabulary, Patient-Level Prediction, ATLAS, Open Source Community, and Psychiatry.

Everybody is invited. Calendar invites went out last week. If you did not receive one, 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.


Upcoming Workgroup Calls – OHDSI


Congratulations to the team of Martin Boeker, Daniela Zöller, Romina Blasini, Philipp Macho, Sven Helfer, Max Behrens, Hans-Ulrich Prokosch and Christian Gulden on the publication of Effectiveness of IT-supported patient recruitment: study protocol for an interrupted time series study at ten German university hospitals in Trials.

Congratulations to the team of Moshe Zisser and Dvir Aran on the publication of Transformer-based time-to-event prediction for chronic kidney disease deterioration in JAMIA.


Registration is now OPEN for the 2024 OHDSI Europe Symposium, which will be held June 1-3 in Rotterdam, Netherlands. There will be tutorials and workshops June 1-2 at the Erasmus University Medical Center, and the main conference will be held Monday, June 3, on the Steam Ship Rotterdam. Please visit the event homepage for more information and registration details.

• Henrik John recently announced a new network study that he is leading with Chungsoo Kim, Jenna Reps and Egill Fridgeirsson on “Deep Learning Comparison.” The aim is to assess the value of deep learning methods over conventional methods for the development of clinical prediction models. The specific diseases under consideration are dementia in individuals over titi, lung cancer in those over 4ti, and bipolar disorder in patients misdiagnosed with major depressive disorder. If you would like to join this effort, please read this forum post for more information and reach out to the study leads by March 1.

• James Weaver, an Associate Director of Observational Health Data Analytics at Janssen Research and Development, will speak during a panel session on Current Approaches for Distributed Analysis on Thursday, March 14 (1 pm ET) during a Health Data Research Network Canada event. This will be a virtual conversation; more information and a registration link are available here.

• Under the leadership of Azza Shoaibi, Anna Ostropolets, Gowtham Rao and James Weaver, Phenotype Phebruary 2024 focuses on assessing consistency in phenotype definition components, phenotype representation structure, and phenotype validation methods. The month-long activity empowers OHDSI collaborators to engage with each other while advancing the science of phenotyping and gaining education and training around phenotype development and evaluation. You can check out the event homepage here.

• Research from the 2023 Global Symposium Collaborator Showcase can be viewed on the Global Symposium Showcase page. Research is also being shared daily on OHDSI’s LinkedInTwitter/X and Instagram feeds as part of the #OHDSISocialShowcase. Below are posters (with study leads) that are featured this week:

Monday — Challenges and opportunities in adopting OMOP-CDM in Brazilian healthcare: a report from Hospital Israelita Albert Einstein (Maria Abrahao)

Tuesday — Developing a pregnancy algorithm in ATLAS: Applying start date offset (Rupa Makadia)

Wednesday — Creating parsimonious patient-level prediction models using feature selection (Aniek Markus)

Thursday — From Complexity to Clarity: Reproducible and Scalable Phenotype Development and application of LLM in a support role (Asieh Golozar)

Friday — Establishing and Operating the OHDSI Dentistry Workgroup: A Model for Other Disciplines (Danielle Boyce)
