What shipped at OMOPHub in May: → Node.js / TypeScript SDK v1.0 (npm) → Python, R, MCP - FHIR-to-OMOP IG conformance → 14 admin FHIR ConceptMaps → Complete Node SDK docs omophub.com #OMOP #OHDSI #FHIR #MCP

Why Tuesdays are so special? It's the day when OMOPHub gets maximum new users during the week. And I observe this during last few months.

OMOPHub April recap: - FHIR Terminology Service - Hosted MCP Server: AI agents query OMOP in <1 min - AI agent docs: llms.txt, skill.md, OMOP-Loop pattern - Python & R SDKs v1.7 with FHIR interop +50% users 3x API calls Keep shipping #OMOP #OHDSI #HealthTech #FHIR #MCP #AI

My colleague fell from a chair today. He's fine. But we had to check: is there a code for that? ICD-10-CM W07: "Fall from chair" SNOMED 4308870 🤣 Connect your AI editor with OMOPHub MCP omophub.com/changelog/2026… What's the weirdest medical code you know? 👇

Everyone told me OHDSI is an R world. So I built the R SDK first for omophub.com. Then I looked at our usage data. 80% Python. 15% R. The community is changing faster than its reputation. What do you use for OMOP work? 👇 #OHDSI #OMOP #Python #RStats

A data engineer told me his team spent 2 weeks aligning vocabularies across 3 sites before running anything. The study design was done. HADES scripts were ready. Vocabulary setup wasn't. With EHDS, that's not just lost time. It's a methodology problem. omophub.com/ehds

Big update to omophub.com's search API: Query "CHF diabetis" finds "congestive heart failure diabetes" New features: - Medical abbreviation expansion - Typo correction - Hybrid lexical+semantic fusion - Optimized pgvector queries (HNSW index)

Semantic Search for Python & R SDKs! Just Shipped! Find OMOP concepts using natural language. Now natively in both SDKs. "heart attack" → Myocardial infarction "sugar diabetes" → Type 2 diabetes mellitus Changelog: omophub.com/changelog/sdk-… #OMOP #OHDSI

Yes, that's a real query. And yes, it works now. I open-sourced an MCP server for OMOPHub giving AI agents access to 10M+ standardized medical concepts instead of hallucinating codes. 🔗 github.com/OMOPHub/omophu…

@JeremyBssnt Congrats There is life BEFORE and AFTER. You will enjoy it

@marclou @marclou as an next idea to add co-founder search/marketplace. I see big demand on reddit and known solution charges $500+ for participation.

@vitddnv Breakfast -> Gym. Looks like, not healthy approach

"Include all SGLT2 inhibitors" Okay. That means mapping: - Empagliflozin - Dapagliflozin - Canagliflozin - Ertugliflozin - Sotagliflozin - Every combination product - Every dose formulation One ingredient concept or 200 clinical drugs? #HEOR #OMOP #RWD

@TuominenPiia There are few more codes across different terminology omophub.com/tools/concept-…
