Description

Codes indicating diagnosis of asplenia or dysplenia (acquired or congenital)

Methodology

This codelist was derived by the following method:

  • Read 2 Codelist provided by LSHTM. See references for paper.
  • Codes from Quality Outcome Framework (QOF) were examined and relevant spleen codes taken
  • Codes from SNOMED were taken by searching for relevant spleen terms

These 3 lists were mapped into CTV3 by TPP to create one list. This list was examined by 2 people and the following logic applied (see github issue for more detail):

  • Splenomegaly or splenic cysts excluded as no evidence of reduced function
  • Congenital syphilis which appears in the list due to one code with congenital syphilitic splenomegaly was excluded. Congenital syphilitic splenomegaly was included however.
  • All unspecified injuries to spleen for example trauma were excluded except where removal of spleen was specified.
  • Removal of accessory spleen was excluded

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.
