Abstract
Background
Current recommendations do not support the use of anti-reflux medications to treat gastro-oesophageal reflux disease (GORD) among preterm infants.
Objective
To describe the prevalence of GORD and the use of anti-reflux medications amongst very preterm infants (<32 weeks’ gestational age (GA)) in neonatal units in England and Wales.
Design
Retrospective cohort study using the National Neonatal Research Database.
Results
Among 58,108 infants [median GA (IQR) 29 (27–30) weeks], 15.8% (n = 9191) had a diagnosis of GORD and 36.9% (n = 12,446) received anti-reflux medications. Those who received anti-reflux medications were more preterm [GA, median (IQR): medications, 28 (26–30) vs. no medications, 30 (28–31); p < 0.001] and had lower birth weight [mean (SD): medications, 1124 g (354) vs. no medications, 1265 g (384); p < 0.001]. Most (57%, n = 12,224) received Gaviscon, or Histamine-2 Receptor Antagonist (H2RA) (56%, n = 11,959). Over time, prokinetic use has declined substantially, the use of H2RAs and Gaviscon has reduced although they continue to be used frequently, whilst the use of PPIs has increased.
Conclusions
Anti-reflux medications are frequently prescribed in very preterm infants, despite evidence to suggest that they are not effective and may be harmful. Clear guidelines for diagnosing GORD and the use of anti-reflux medications are required to rationalise the pharmacological management of GORD in preterm infants.
Impact
Anti-reflux medications are frequently prescribed, often without a diagnosis of gastro-oesophageal reflux disease, to very preterm infants while in the neonatal unit and at discharge.
Half of the infants born at <28 weeks’ gestational age receive anti-reflux medications in hospital and a quarter are discharged home on them.
Although the use of prokinetics declined following alerts of adverse events, histamine2-receptor antagonists and alginates such as Gaviscon continue to be used and the use of proton-pump inhibitors has increased more than 2-fold.
