Background Early parenteral nutrition (PN) improves growth in preterm neonates. Good practice in PN-care was identified in only 24% of the units in the NCEPOD-Report.
Aim To compare the growth of preterm infants since the NCEPOD-Report in relation to PN-use.
Methods Retrospective comparison of preterm infants cared for in a tertiary neonatal unit until 36 weeks gestational age (GA) between 2010–2013. Newborns were grouped by gestation (23–30GA/31–36GA) and birth-year. Outcomes were z-scores for birthweight (BWz), discharge-weight (DWz) and length of PN in days (loPN). Outcomes were compared between years, within years and between GA-groups including >36GA-control-group. Data-presentation/-analysis: Median (interquartile-range); Mann-Whitney-U-Test/Kruskal-Wallis-Test (p < 0.05).
Results 175 newborns recruited. No significant difference for BWz and DWz between years and for BWz and DWz between GA-groups within a year except for DWz 2010(p = 0.02). No significant difference for the same GA-group between years except for DWz 23–30GA(p = 0.04). No significant difference for loPN between years and between GA-groups within a year except for 2010(p < 0.0001) and 2011(p < 0.0001). No significant difference for the same GA-group between years except for 31–36GA(p < 0.0001).
Conclusion Growth in preterm infants assessed by difference in z-scores appears to have improved since 2010. This may be partly due to increased PN-use which although not significant shows a notable increase since the NCEPOD-Report.
