*High cost drug codes* etanercept

[NikNakk]

Description

This is a list of all the unique values from the Drug Name variable in the High Cost Drugs Dataset that relate to the prescribing of etanercept.

Methodology

The values in this variable do not follow a coding system so the selection for this codelist is based on the drug name value, after converting all text to lower case, containing one or more of the following strings (these are the generic medicine name and brand names):

• etanercept
• enbrel
• benepali
• erelzi

All drug name values that contain at least one of the above strings are included in the etanercept group and assigned the VTM (virtual therapeutic moiety) code 118259007.

Note there are some entries for 'gain share'; these should still successfully identify people exposed to the drug, but may effectively be duplicate events.
