Quality improvement project designed to reduce disproportionate growth in extremely low gestational age neonates: cognitive neurodevelopmental outcome at 18–41 months

Abstract

Objective

To assess if the adjusted odds of low composite cognitive Bayley-III scores changed after implementing a single-institution quality improvement (QI) project designed to decrease discharge Z-scores for weight, body mass index (BMI), and weight-for-length, but not length or fronto-occipital circumference (FOC) in infants 23–28 weeks gestational age (GA).

Methods

Compare Bayley-III outcomes at ≥18 months corrected age (postnatal age adjusted for prematurity) in infants tested before (Epoch-1) and after (Epoch-2) QI implementation.

Results

Bayley testing was available in 134/156 infants (86%) in Epoch-1 and 139/175 (79%) in Epoch-2. There was no change in frequency of low (<85) cognitive score (p = 0.5) or in median cognitive scores (80 in Epoch-1 vs. 85 Epoch-2, p = 0.35). The adjusted odds of low cognitive scores was not different between Epochs.

Conclusion

No change in cognitive outcome at ≥18 months corrected age was observed after implementing a QI project designed to reduce discharge weight-for-length disproportion in very preterm infants.
