Abstract
Admission to neonatal care causes separation of infants from their parents, can adversely affect breast-feeding and is associated with painful procedures. Our aim was to identify perinatal factors and cost of care associated with transient neonatal hyperinsulinaemic hypoglycaemia (HH). Infants born after 35 weeks of gestation admitted because of hypoglycaemia were studied. The neonates were divided into two groups (HH and non-HH), and their length and cost of care were compared and perinatal factors predicting those outcomes explored. Forty of the 474 infants admitted with hypoglycaemia were diagnosed with HH. The HH group had a lower median (IQR) glucose level on admission compared to the non-HH group (p < 0.001). The median (IQR) cost of stay was higher in the HH group (p < 0.001). In the HH group, the GIRmax was significantly correlated with cost of stay (p < 0.001). GIRmax predicted a cost of stay > £9140 with an area under the ROC curve of 0.956. GIRmax > 13.9 mg/kg/min predicted admission cost > £9140 with 86% sensitivity and 93% specificity. Conclusion: Transient neonatal HH was associated with a higher length and cost of stay in infants admitted for hypoglycaemia. The GIRmax can predict the length and cost of stay. What is Known: • Neonatal hypoglycaemia is the leading cause of term and late preterm neonatal admissions. • Hyperinsulinism (HH) is the commonest cause of persistent hypoglycaemia, and delay in the diagnosis and management can have a detrimental impact on long-term development. What is New: • We have demonstrated prior to NICU admission that blood glucose concentrations were lower in infants with HH compared to those without. • The maximum GIR had a stronger correlation with total length and cost of hospital stay compared to insulin levels in HH infants.
