To determine the sensitivity and specificity of the 21-month neurodevelopmental outcome for predicting the presence of neurodevelopmental impairment at 36 months corrected age in a population of preterm infants under 29 weeks gestation. This is a retrospective observational cohort study. Preterm infants born under 29 weeks gestation who were followed up at both 18-21 months and 36 months corrected age with outcome data available were enrolled. Overall, 713 preterm infants <29 weeks gestation and were included in the final analysis. The specificity of the 21-month assessment for predicting neurodevelopmental impairment at 36 months corrected age was 66% (95% confidence interval[CI] 62-71%) with a positive predictive value of 61% (95% CI 56-66%). In preterm neonates born <29 weeks gestation, the 18-21 months corrected neurodevelopmental outcome had low specificity and positive predictive value for predicting the presence of neurodevelopmental impairment at 36 months corrected age.

D002658 Developmental Disabilities Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment.

D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D015331 Cohort Studies Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
