Description
This codelist comprises 41 diagnostic codes for type 1 diabetes.
Methodology
1) The NHS Data Migration Workbench was used to map version 2 Read codes from an existing diabetes codelist (derived in CPRD) to CTV3 codes, searching up and down the hierarchy at each stage.
2) These codes were then checked against existing Opencodelists diabetes codelists in CTV3 format (opensafelytype1diabetes20200629 and opensafely-diabetes-exeter-group-2020-07-06), which identified one additional diagnostic code. Several codes present in other codelists, e.g. "diabetes screening invitation" were discarded. Additionally, I have categorised codes mentioning "juvenile diabetes" as type 1 diabetes. This term has fallen out of use now but was formerly used to refer to type 1 diabetes.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.
We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
