Support ICD-10 2016

[Jongmassey]

Slack thread.

Summary

• 2016 edition used in HES
  • UK specific modifications of WHO 2016 edition
  • Edition created in 2016 available on TRUD, but no updates since
  • Updates published in NCCS documents and a graphical browser is available
• Subset of WHO 2019 used in ONS Deaths (we believe, but may have/be moving to ICD 11?)
• 2019 is most recent edition loaded into OpenCodelists
• There are meaningful differences between 2016 and 2019
  • One user reports upload of codelist containing 2016 codes gets rejected
  • Upload of codelists for GBD project affected
  • There may be under-ascertainment in EHR analyses if codelists created using 2019 edition are used against datasets coded using 2016 edition

What did you do and what did you expect to happen?

As a researcher, I want to be able to use the correct release/edition of ICD 10 for the datasets I'm using in my study.

Impact of the bug

• Current ICD 10 codelists (n~=1300) may be missing codes that are present in 2016 edition but not 2019 which results in under-ascertainment when used against HES datasets. Conversely, codes included in codelists that are present in 2019 edition but not 2016 edition will never match data in HES.
• Users cannot upload codelists that contain codes present in ICD 10 2016 but not ICD 2019

I'm removing this from the board, while Team RSI do some more investigation, and until we know whether we've going to work on this.
