OHDSI/OMOP Train-the-Trainer

A hands-on, multi-session curriculum for analysts, researchers, and trainers building expertise in the OHDSI ecosystem — from data model fundamentals to advanced analytics.

New here? Start with Feasibility First — is my question even answerable?

A 30-minute exemplar that takes the position of a researcher with a real question but no idea who to contact, what to ask, or whether the data can answer it. It walks from zero to a go/no-go decision on the public ATLAS demo, and it comes with a slide deck, an importable ATLAS cohort, a data-steward worksheet, and a checks-to-tools appendix.

How to Use This Site

For Participants

  1. Complete Module 0 before anything else — verify your tool access at least 48 hours before Day 1.
  2. Follow the core track in order. Each day's module has an agenda, objectives, slides, and a matching exercise.
  3. Use the Common Artifacts for cheat sheets, SQL templates, and the environment checklist.
  4. Notebooks are always available. Each exercise page has a Colab badge — run it with synthetic data even without CDM access.

For Trainers

  1. Fork this repository and fill in site-specific details (warehouse, SQL client, ATLAS URL) in the Day 4 module and Environment pages.
  2. Use the branded templates from the Downloads & Resources page for any new decks.
  3. Instructor notes are embedded (collapsed) in each exercise page — expand them before your session.
  4. Host community meetings using the Community pages as a template.
