Parental education and family income had significant influence on postdischarge mortality. Two thirds of infants demonstrated neurodevelopmental impairments. Most mild cognitive impairments would have been missed had either physicians or psychologists alone done the assessments. Preterm infants in this low-resource setting are at high risk for neurodevelopmental impairments, which need to be identified early, preferably by a multidisciplinary team of professionals.

The RNDA can be used by professionals from a range of backgrounds with high reliability and validity for determining functional status of children who are younger than 2 years. The study findings have important practical implications for early identification and intervention to mitigate neurodevelopmental impairments in large populations that live in developing countries where professional expertise is sparse.

The RNDA validity results are promising for use by child care professionals in field and clinical settings, but the tool needs further replication and refinement for assessment of specific impairments of vision, hearing, and seizures.

A tool for screening <2-year-old children at risk for NDIs showed high specificity; and was able to identify all children at risk for vision and hearing impairments, nearly three-fourths with speech impairments, two-thirds with gross motor impairments, and about half with behavioural, cognitive and fine motor impairments. The Developmental Screening Questionnaire tool has potential for use by frontline workers to screen large populations and to link to definitive assessment as well as intervention services.

As survival of preterm infants in low resource settings increases, ROP will become increasingly important as a potential cause of blindness, emphasizing the critical need for ophthalmologic examination in premature infants, with immediate initiation of treatment when ROP is diagnosed.
