Description

dm+d codelist for oral methotrexate

Methodology

This codelist was developed based on methodology used in the DataLab paper on trends and variation in unsafe prescribing of methotrexate published in the British Journal of General Practice. All oral methotrexate preparations from chapter 10 of BNF codes were included although the vast majority of prescriptions will be for tablets. You can view the BNF codelist version here

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.

* dm+d codelists can be downloaded with codes mapped to changed VMPs included - this is the default for an OpenSAFELY project. See the documentation on keeping codelists up to date for more details.

* Note that this is the full list of explicitly included dm+d codes for this codelist. An OpenSAFELY project will by default also include previous or subsequent codes for any included VMPs that may have changed code. See the documentation on keeping codelists up to date for more details.
