Abstract: Objective: To determine whether neurobiologic risk score (NBRS) would continue to correlate with developmental outcomes. Method: An observational cohort consisting of 258 surviving infants who returned to the follow-up clinic with a mean age 22 months' corrected age. Both univariate and multivariate analysis were performed to identify risk factors and to assess the predictive value of NBRS. Results: Forty-eight to 53 per cent of these infants had growth parameters < 25thpercentile for age. Seventeen and 18 per cent respectively had mental developmental index (MDI) and psychomotor developmental index (PDI) on the Bayley Scales less than 70 and 14 per cent developed cerebral palsy (CP). NBRS demonstrated a significant correlation with the outcome (p<0.001). In infants with NBRS ≤ 8, 48 per cent had MDI < 70 and 68 per cent, had PDI < 70. At a similar NBRS cut-off, specificity and negative predictive value (NPV) were 86 and 96 per cent, respectively. Logistic regression indicated that birth weight and gestational age were the most significant. independent variables for predicting poor outcomes. Conclusion: Very preterm infants in the present study were at risk for abnormal developmental outcomes. NBRS demonstrated a very high specificity and NPV and may be a useful index to identify those who need early intervention.
