Executive Summary
During the February 7, 2025 Phenotype Phebruary Office Hours, the group focused on ensuring that 14 ongoing studies finalize their clinical descriptions and record them in a centralized progress tracker. Organizers emphasized prompt engineering for ChatGPT-based drafting, recognizing both the tool’s usefulness and the need for expert review. Several leads shared their experiences—highlighting successes and limitations in adapting ChatGPT outputs for conditions, drug exposures, or procedures.
Participants also discussed leveraging existing resources (e.g., the OHDSI Phenotype Library, PubMed) for validated algorithms, while acknowledging the challenges in converting older ICD-9-based definitions to ICD-10. Attention turned to cohort construction in Atlas Demo, where record counts in the OHDSI Evidence Network inform concept set choices. With Tuesday’s community call approaching, the group agreed on final deadlines for uploading clinical descriptions and setting up concept sets. Two volunteers (Tatsiana and Kevin) will demonstrate live how they develop phenotypes—one focusing on first-episode psychosis, the other adapting inflammatory bowel disease definitions—showcasing the detailed steps, sharing lessons, and clarifying best practices for building robust, reproducible cohorts.
