Insights
Neurodevelopmental follow-up is vital for preterm infants to monitor for disabilities. Standardized developmental tests at corrected age 2 years are recommended for accurate assessment in high-risk neonates.
Area of Science:
- Neonatal care
- Developmental pediatrics
- Neuroscience
Background:
- Preterm infants face a high risk of residual disability, necessitating careful outcome monitoring.
- National recommendations emphasize neurodevelopmental follow-up until at least 2 years corrected age.
- Developmental assessment at 2 years is crucial for identifying disabilities in this population.
Purpose of the Study:
- To review standardized developmental tests for assessing preterm infants.
- To discuss practical considerations for using these tests in neonatal follow-up.
- To provide guidelines for developmental testing at 2 years corrected age.
Main Methods:
- Review of commonly used standardized developmental tests for infancy.
- Discussion of the properties and utility of standardized tests versus screening tools.
- Consideration of parental reports in developmental assessment.
Main Results:
- Standardized developmental tests are more diagnostic and suitable for high-risk populations than screening tools.
- Practical issues in applying these tests to preterm infants are outlined.
- Guidelines for 2-year developmental testing are provided.
Conclusions:
- Standardized developmental tests are essential for accurate outcome measurement in preterm infants.
- Effective implementation requires addressing practical challenges in testing.
- Comprehensive follow-up aids in identifying and managing neurodevelopmental impairments.
Abstract:
Given the high risk for residual disability in preterm infants, outcome monitoring is a crucial function of neonatal care. Provision of neurodevelopmental follow-up to at least 2 years of age corrected for prematurity forms part of national recommendations for neonatal services. This should include a developmental assessment at 2 years to identify disability. Although screening tools are cost and time efficient measures, they are not diagnostic and have less utility in high-risk populations. In contrast, standardised developmental tests are ideally suited for follow-up purposes and have become widely accepted as outcome measures. We highlight the properties of standardised tests and review the most commonly used tools for assessment in infancy. We also outline a number of practical issues in the use of standardised tests with preterm infants in identifying morbidity and predicting later impairment. Parental reports are also discussed and key guidelines for developmental testing at 2 years are provided.
