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.

Strong Opioids BNF
User requirements

A codelist is needed of all strong opioids used for analgesia (any route) excluding cough suppression, motility, general anaesthesia, opiate use disorder - this is for a project looking at opioid prescribing for patients on hospital waiting lists. This will use the BNF definition of strong opioids https://bnf.nice.org.uk/treatment-summaries/analgesics/

Sensitivity versus specificity

All strong opioids
