OpenCodelists

Welcome to OpenCodelists, created by OpenSAFELY for creating and sharing codelists.

Anybody can also use this tool to create and share codelists. To get started, take a look at the documentation or watch the videos.

If you would like to publish codelists on behalf of an organisation, please get in touch.

Below, you'll find all the codelists that have been used in OpenSAFELY research to date.
