  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    Codes indicating diagnosis of aplastic anaemia

  3. 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
