Neonatal diseases severity scoring systems

Illness severity scores have become widely used in neonatal intensive care. Primarily this has been to adjust the mortality observed in a particular hospital or population for the morbidity of their infants, and hence allow standardised comparisons to be performed. However, although risk correction has become relatively commonplace in relation to audit and research involving groups of infants, the use of such scores in giving prognostic information to parents, about their baby, has been much more limited. The strengths and weaknesses of the existing methods of disease severity correction in the newborn are presented in this review.
