Bacterial Meningitis Score for Children

Identifies children with CSF pleocytosis at low risk of bacterial meningitis who may not require empirical antibiotics. Score ≥2 or any high-risk feature = treat as bacterial.

Used in: Meningitis & Encephalitis

Score interpretation

Low Risk (<1%) 0

Score 0 — bacterial meningitis risk <1%. Negative predictive value 99.3%.

→ Consider withholding antibiotics; admit for observation; close monitoring required; clinical assessment paramount — do NOT use score alone in toxic-appearing child

Intermediate Risk 1

Score 1 — intermediate risk. Clinical judgment required.

→ Consider empiric antibiotics; discuss with paediatric specialist; close monitoring

High Risk — Treat as Bacterial 2–5

Score ≥2 — bacterial meningitis likely

→ Empiric IV antibiotics immediately (ceftriaxone ± dexamethasone); blood cultures before antibiotics; urgent paediatric and ID review
