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 we have used in OpenSAFELY research to date.

We are aware that some of the individual codes contained in this codelist are offensive and upsetting. Although these terms are outdated and no longer in routine use, it is necessary to include them in codelists due to the historic nature of the data that is being analysed. Excluding these terms would reduce the completeness of the data and may mean that some people with a learning disability are not included in the analyses.
