Risk Factors for Mortality and Neurodevelopmental Impairment among Neonates Born at 22-23 Weeks' Gestation

Screening for Neurodevelopmental Delay for Preterm Very Low Birth Weight Infants at Tertiary Care Center in Saudi Arabia

Background

Preterm infants are more susceptible to death, short-term complications, and long-term complications such as neurodevelopmental impairments. However, definitive assessment tools are not available in a resource-limited setting. Hence a screening tool is needed the Arabic-speaking population.

Method

Infants born at a gestational age of <32 weeks or a very low birth weight (VLBW) of less than 1500 g were recruited into a cross-sectional study. We identified infants (n = 61) admitted to the neonatal ICU at King Abdulaziz Medical City and reached 18 up to 24 months of corrected gestational age (CGA). The developmental assessment was done at 18, 20, 22, and 24 CGAs using the Ages and Stages Questionnaire third edition - Arabic version (ASQ3-A). The primary outcomes are early detection rate of neurodevelopmental delay (NDD), defined as a delay in one or more of the following: communication, gross motor, fine motor, problem-solving, and personal-social skills as per ASQ3-A.

Results

Sixty-one out of 92 eligible infants (36 excluded) completed the sufficient assessment. Twenty-six infants (42.6%) had at least one NDD in one of the following domains: communication skills: (11.5%), gross motor: (11.5%), fine motor: (19.7%), problem-solving skills: twelve infants (19.7%), and personal-social skills: twenty infants (23%). Perinatal events and periventricular leukomalacia (PVL) were significant independent predictors for the NDD.

Conclusion

This single-center study in Saudi Arabia screened preterm, VLBW infants based on ASQ3-A, twenty infants (42.6%) had an abnormal NDD at a corrected age of 18-24 months. Perinatal events and PVL were independent predictors of NDD. We recommend that all preterm VLBW infants in Saudi Arabia be evaluated by a neurodevelopmental screening tool, ASQ3-A, especially in resource-limited settings to start early intervention. Also, more extensive multicenter studies are to be carried out with definitive diagnostic tools to have a national benchmark for the long-term neurodevelopmental impairment.
