Description

Codes indicating diagnosis of aplastic anaemia

Methodology

This codelist was derived by the following method:

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

These 3 lists were mapped into CTV3 by TPP to create one list. This list was examined by 4 people and the following logic applied (see github issue for more detail):

  • Pure red cell aplasia excluded
  • Pancytopenia NOS was excluded from this list but included in the temporary immunosuppression list
  • T-cell mediated cytopenia excluded as it's thought to be a mechanism to cause aplastic anaemia but also possibly ITP and other single cell line reductions
  • Hypoplastic haemolytic and renal anaemia drugs 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.
