Chronic anaemia (primary care)
Name chronicanaemia_gprd
Chapter Diseases of the blood/Chronic anaemia
Definition
Definition of chronic anaemia, or disease causing chonic anaemia, categorised into broad types (nutritional, aplastic, haemolytic) with separate categories for sickle cell disease and thalassemia. Enzyme disorders causing anaemia are included even if the Read term does not specify
anaemia, to make it consistent with the ICD-10 hierarchy. Nutritional anaemia in pregnancy is classified under pregnancy. Version 2 of this codelist includes myelodysplasia as a separate category.
