Pediatric intracerebral hemorrhage score: a simple grading scale for intracerebral hemorrhage in children.

BACKGROUND AND PURPOSE The intracerebral hemorrhage (ICH) score is the most commonly used clinical grading scale for outcome prediction after adult ICH. We created a similar scale in children to inform clinical care and assist in clinical research. METHODS Children, full-term newborns to 18 years, with spontaneous ICH were prospectively enrolled from 2007 to 2012 at 3 centers. The pediatric ICH score was created by identifying factors associated with poor outcome. The score's ability to detect moderate disability or worse and severe disability or death was examined with sensitivity, specificity, and area under the receiver operating characteristic curve. RESULTS The pediatric ICH score components include ICH volume>2% to 3.99% of total brain volume (TBV): 1 point; ICH volume≥4% TBV: 2 points; acute hydrocephalus: 1 point; herniation: 1 point; and infratentorial location: 1 point. The score ranges from 0 to 5. At 3-month follow-up of 60 children, 10 were severely disabled or dead, 30 had moderate disability, and 20 had good recovery. A pediatric ICH score≥1 predicted moderate disability or worse with a sensitivity of 75% (95% confidence interval [CI], 59% to 87%) and a specificity of 70% (95% CI, 46% to 88%). A pediatric ICH score≥2 predicted severe disability or death with a sensitivity and specificity of 90% (95% CI, 55% to 99%) and 68% (95% CI, 53% to 80%), respectively. The area under the receiver operating characteristic curve for classifying outcome as severe disability or death was 0.88 (95% CI, 0.78-0.97). CONCLUSIONS The pediatric ICH score is a simple clinical grading scale that may ultimately be used for risk stratification, clinical care, and research.
