Abstract

To evaluate predictors of poor outcome, including the CRIB (Clinical Risk Index for Babies) score, in a local population of very-low-birth-weight (VLBW) infants, in order to provide guidelines for selection of these babies for expensive tertiary care. Two hundred and thirty-one neonates born at less than 31 weeks' gestation and/or weighing between 1001 g and 1500 g, enrolled prospectively as part of a multicentre study evaluating the CRIB score. Univariate analysis (chi-square/t-tests) and multivariate analysis (stepwise logistic regression) on the above sample to determine predictors of poor outcome. Neonatal Unit, Johannesburg Hospital. Death or impairment (namely oxygen therapy > 28 days, grade 3 or 4 intraventricular haemorrhage, or ventricular enlargement). Poor outcome was predicted by birth weight, lowest oxygen requirement in the first 12 hours (which are two components of the CRIB score), and maximum partial arterial carbon dioxide pressure (PaCO2) in the first 72 hours. Other factors, including the full CRIB score, were not predictive of outcome. One method of selection of infants for expensive tertiary care is on the basis of predicted outcome. Birth weight remains a reasonable basis for this selection, but the inclu...Continue Reading
