Identifies children with CSF pleocytosis who are at very low risk of bacterial (vs aseptic) meningitis (Nigrovic).
Positive CSF Gram stain, CSF ANC ≥1000 cells/µL, CSF protein ≥80 mg/dL, Peripheral blood ANC ≥10,000 cells/µL, Seizure at or before presentation.
Applies only to children >2 months with CSF pleocytosis who are not critically ill or immunocompromised. Local guidelines and clinical judgement override the score.
Estimates the likelihood of group A streptococcal pharyngitis to guide testing and antibiotics, with McIsaac age adjustment.
Estimates the likelihood of streptococcal pharyngitis to guide antibiotic decisions (0–5).
