The CRIB II score is an updated and simplified scoring system for neonates receiving intensive care. It is better calibrated with current data compared to the original CRIB score. The authors are from the UK Neonatal Staffing Study Collaborative Group.
Parameters:
(1) birthweight
(2) gender
(3) gestational age
(4) temperature at admission in °C
(5) base excess in mmol/L

total CRIB II score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 27
• The higher the score, the greater the mortality.
X =
= (0.450 * (CRIB II score)) – 6.476
probability of mortality =
= EXP(X) / (1 + EXP(X))
Purpose: To evaluate a neonate in the neonatal intensive care unit using the CRIB II score.
Specialty: Critical Care, Emergency Medicine, Pedatrics
Objective: risk factors, severity, prognosis, stage
ICD-10: R57, P29,
