Codes indicating a diagnosis of HIV


Read v2 codes from previous work were combined with relevant QoF codes and SNOMED terms, identified from the NHS Digital SNOMED browser. The combined codes were translated to Read CTV 3 and reviewed by team members with clinical and epidemiological expertise. Following early descriptive analyses, three codes (XaFuN, XaFuO and 43CZ.) were removed from the list as these appeared to represent HIV testing (notably in large numbers of young women, likely at pregnancy), rather than HIV positive status.

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.
