Management of Neonatal Hyperglycaemia in Sweden-A Survey Study.

Abstract

Aim: Neonatal hyperglycaemia is associated with a multitude of adverse outcomes, including mortality and impaired neurological development. The aim of this study was to characterise the current management of neonatal hyperglycaemia in Swedish neonatal units.

Methods: A digital survey was sent to 27 Swedish neonatal units providing care to preterm infants born before 32 completed gestational weeks.

Results: Sixty-eight responses were collected from 21 different units. Thirty-two percent (22/68) of clinicians reported having a local treatment guideline for neonatal hyperglycaemia. Hyperglycaemia was defined as a glucose concentration above a value in the range of 8.0-10.0 mmol/L by 62.5% of clinicians, while 16.7% and 21.8% used a definition between 10.1 and 12.0 mmol/L and > 12 mmol/L, respectively. Intravenous glucose reduction was initiated at higher glucose concentrations by clinicians working at university hospital units (p = 0.006). Glucose concentration threshold for initiation of insulin treatment varied between 8 and 30 mmol/L. Three clinicians (3/35 (8.5%)) reported having experienced problems with frequent hypoglycaemia during ongoing insulin treatment.

Conclusions: This study demonstrates extensive differences in clinical practice regarding neonatal hyperglycaemia both within and between neonatal units in Sweden. Randomised controlled trials are needed to provide evidence for clinical guidelines and to improve and standardise the care of these infants.
