Abstract

    Purpose: The importance of the neurodevelopmental outcomes of very-low-birth-weight (VLBW)infants has been emphasized as their mortality rate has markedly improved. This study aimed to assessthe validity of the Korean Developmental Screening Test (K-DST), a developmental screening toolapproved by the Korean Society of Pediatrics, for the timely diagnosis of neurodevelopmental delay inVLBW infants.

    Methods: Subjects included VLBW infants enrolled in the Korean Neonatal Network database betweenJanuary 2012 and December 2014. The collected data were analyzed for sensitivity, specificity,positive predictive value, and negative predictive value (NPV) in the K-DST compared to those in theBayley Scales of Infant Development-II for VLBW infants.

    Results: A total of 173 patients were enrolled. Their mean gestational age and mean birth weight were27.5±2.8 weeks and 980.5±272.1 g, respectively. The frequency of failed psychomotor developmentalindex (PDI) <85 was similar to that in at least one domain of K-DST <1 standard deviation. Failurein more than one K-DST domain compared with a mental developmental index (MDI) <85 showeda sensitivity and NPV of 73.2% and 75.0%, respectively. Failure in more than one K-DST domaincompared with PDI <85 showed a sensitivity and NPV of 60.3% and 71.6%, respectively. Each K-DSTdomain had a stronger correlation with predicting a failing MDI <85 than a failing PDI <85 (P<0.05).

    Conclusion: K-DST could be a useful screening tool for predicting mental developmental delay inVLBW infants and referring them for neurodevelopmental assessments.
