The purpose of this study is to assess the possibility of predicting mortality, major pathology and long-term neurodevelopmental impairment in very low birth weight VLBW infant using Clinical Risk Index for Babies (CRIB). We studied a cohort of 251 VLBW infants, whose CRIB could be calculated, born from 1995 to 1998 in our Unit. We analyzed the mortality before discharge, the incidence of chronic lung disease (CLD) and of retinopathy of prematurity (ROP), the length of stay before discharge and the neurodevelopmental impairment at one and two years of corrected age using the Griffiths developmental scales (impairment was defined by a general quotient of 85 or below). The CRIB score was divided into three risk groups: 0-5, 6-10 and > 10. Mortality rate raises with the CRIB's increase (respectively 5.6% in the first group, 32.4% in the second and 93.8% in the third group); besides the incidence of severe ROP and of CLD, calculated in infants survived > 28 days, is higher (18.4% and 40.7% respectively) in the second group than in the first (1.9% and 7.4% respectively). In the end, the incidence of neurodevelopment impairment at one and two years of corrected age is respectively 6.8% and 6.0% for children with CRIB 0-5 and 29.4% and 21.4% for children with CRIB 6-10. CRIB score is strongly associated with mortality and there is an increasing risk for severe ROP, CLD and neurodevelopment impairment from class 0-5 to class 6-10; no statement can be made for these diseases in class > 10 because there is only one survivor in this class.

Abstract
The purpose of this study is to assess the possibility of predicting mortality, major pathology and long-term neurodevelopmental impairment in very low birth weight VLBW infant using Clinical Risk Index for Babies (CRIB). We studied a cohort of 251 VLBW infants, whose CRIB could be calculated, born from 1995 to 1998 in our Unit. We analyzed the mortality before discharge, the incidence of chronic lung disease (CLD) and of retinopathy of prematurity (ROP), the length of stay before discharge and the neurodevelopmental impairment at one and two years of corrected age using the Griffiths developmental scales (impairment was defined by a general quotient of 85 or below). The CRIB score was divided into three risk groups: 0-5, 6-10 and > 10. Mortality rate raises with the CRIB's increase (respectively 5.6% in the first group, 32.4% in the second and 93.8% in the third group); besides the incidence of severe ROP and of CLD, calculated in infants survived > 28 days, is higher (18.4% and 40.7% respectively) in the second group than in the first (1.9% and 7.4% respectively). In the end, the incidence of neurodevelopment impairment at one and two years of corrected age is respectively 6.8% and 6.0% for children with CRIB 0-5 and 29.4% and 21.4% for children with CRIB 6-10. CRIB score is strongly associated with mortality and there is an increasing risk for severe ROP, CLD and neurodevelopment impairment from class 0-5 to class 6-10; no statement can be made for these diseases in class > 10 because there is only one survivor in this class.
