Codebook
The shared foundation
A shared, organization-owned library of clinical code lists and phenotype definitions — the diagnosis, drug, and procedure codes that turn a research concept into something computable. Codebook builds and versions each definition with full provenance, then feeds it directly into Protocol Studio and SAP Studio, so the same vetted definition is reused across every study instead of being re-created study by study.

How it works
From a clinical concept to a reusable definition
A code list isn't a one-off — it's an asset. Codebook builds each definition once, keeps it governed and versioned, and puts it to work everywhere it's needed.
- 01
Define the concept
Start from a clinical concept — a condition, exposure, or outcome — and Codebook assembles candidate code lists across standard vocabularies.
- 02
Search & verify
Search accepted terminologies and verify each code against authoritative sources, so every list is grounded, current, and complete.
- 03
Govern & version
Every list is owned by your organization, versioned, and tagged by provenance — generated or curated — with a full history of what changed and why.
- 04
Reuse everywhere
Vetted definitions flow straight into Protocol Studio and SAP Studio, so every study is built on the same governed source of truth.
Why it matters
Reusable, governed, consistent across every study
Inconsistent code lists are a quiet source of error and wasted effort — the same phenotype rebuilt slightly differently in every study. Codebook makes each definition a governed, shared asset, so your research program stays consistent and every study rests on the same defensible foundation.
One source of truth
Every study draws from the same governed library, so definitions stay consistent across your whole research program.
Provenance on every code
Each list is tagged generated or curated and fully versioned, so you always know where a definition came from and how it changed.
Standards-grounded
Code lists are built and verified against accepted clinical terminologies like SNOMED, ICD, and RxNorm.
Feeds the whole platform
Definitions carry straight into protocols and analysis plans — no re-keying, no drift between studies.
