Score interpretation

Grade 1 — Mild Anaemia 1

Hb ≥10 g/dL. Mild anaemia. Monitoring only.

→ Investigate cause. No transfusion indicated. Iron/B12/folate supplementation if deficient.

Grade 2 — Moderate Anaemia 2–3

Hb 8.0–9.9 g/dL. Moderate anaemia.

→ Consider iron, EPO (if chemotherapy-related), or transfusion if symptomatic. Review dose of causative agent.

Grade 3 — Severe Anaemia 4–5

Hb 6.5–7.9 g/dL. Severe anaemia.

→ Red cell transfusion indicated (threshold typically Hb <7–8 g/dL or symptomatic). Consider holding/reducing causative chemotherapy. Haematology review.

Grade 4 — Life-threatening 6–7

Hb <6.5 g/dL. Life-threatening anaemia.

→ Urgent blood transfusion. Identify and treat cause urgently. Haematology emergency consultation. Consider ICU if cardiovascular compromise.
