Adherence to neonatal hypoglycaemia guidelines: A retrospective cohort study

Area of Science:

• Neonatal Medicine
• Pediatric Endocrinology
• Clinical Quality Improvement

Background:

• Neonatal hypoglycaemia is a common concern requiring adherence to specific management guidelines.
• Current adherence to neonatal hypoglycaemia guidelines can be suboptimal, potentially impacting infant outcomes.
• Birthweight centiles are a key indicator for assessing neonatal risk, but their routine use in guideline adherence is not well-established.

Purpose of the Study:

• To evaluate if the routine implementation of automatically calculated birthweight centiles enhances adherence to neonatal hypoglycaemia management protocols.
• To assess the impact of using birthweight centiles on the detection rates of neonatal hypoglycaemia in at-risk newborns.

Main Methods:

• Retrospective audit of neonatal records in a tertiary maternity hospital.
• Comparison of guideline adherence in infants before (2011) and after (2015) the introduction of routine birthweight centile calculation.
• Defined adherence by blood glucose screening timing, frequency, and threshold values.

Main Results:

• Guideline adherence significantly improved from 30% in 2011 to 48% in 2015 (P < 0.001).
• The most substantial improvement was observed in large-for-gestational age infants (14% to 50%, P < 0.001).
• Adherent care was associated with a higher detection rate of hypoglycaemia (42% vs. 14%, P < 0.001).

Conclusions:

• Routine calculation and use of birthweight centiles are associated with better adherence to neonatal hypoglycaemia guidelines.
• This practice leads to increased detection of neonatal hypoglycaemia in at-risk infants.
• Optimizing clinical practices, such as using birthweight centiles, can improve the identification of hypoglycaemia in asymptomatic newborns.
