Objective The objective of this study was to examine the association between umbilical catheters and a composite outcome of mortality or major neonatal morbidity in extremely preterm infants. Study Design Data were abstracted from the Canadian Neonatal Network database for infants born at <29 weeks' gestational age and admitted to 29 neonatal intensive care units between January 2010 and December 2012. Four groups were identified: those with no umbilical catheters, umbilical venous catheters (UVCs), umbilical artery catheters (UACs), and those with both UVCs and UACs. The outcomes were compared among the groups using univariate and multivariable analyses. Results Of 4,623 eligible infants, 820 (17.7%) had no catheters, 1,032 (22.3%) a UVC only, 120 (2.6%) a UAC only, and 2,651 (57.3%) had both catheters. After adjustment for acuity and other potential confounders, umbilical catheters were associated with higher odds of mortality or any major morbidity (UVC vs. no catheter: adjusted odds ratio [aOR]: 1.47; 95% CI: 1.18-1.85; UAC vs. no catheter: aOR: 1.67; 95% CI: 1.05-2.63; and both UVC + UAC vs. no catheter: aOR: 2.17; 95% CI: 1.79-2.70). Conclusion Most of the infants born at <29 weeks' gestation had UVC and/or UAC placement. The presence of either catheter was associated with mortality or major morbidity, and the association was stronger when both catheters were present. [ABSTRACT FROM AUTHOR] more...

Objective: To examine rates and determinants of home nasogastric (NG)-tube feeding at hospital discharge in a cohort of very preterm infants within the Canadian Neonatal Network (CNN).<bold>Study Design: This was a population-based cohort study of infants born <33 weeks of gestation and admitted to neonatal intensive care units (NICUs) participating in the CNN between January 1, 2010, and December 31, 2018. We excluded infants who had major congenital anomalies, required gastrostomy-tube, or were discharged to non-CNN facilities. Multivariable logistic regression analysis was used to identify independent determinants of home NG-tube feeding at hospital discharge.Results: Among the 13 232 infants born very preterm during the study period, 333 (2.5%) were discharged home to receive NG-tube feeding. Rates of home NG-tube feeding varied across Canadian NICUs, from 0% to 12%. Determinants of home NG-tube feeding were gestational age (aOR 0.94 per each gestational week increase, 95% CI 0.88-0.99); duration of mechanical ventilation (aOR 1.02 per each day increase, 95% CI 1.01-1.02); high illness severity at birth (aOR 1.32, 95% CI 1.01-1.74); small for gestational age (aOR 2.06, 95% CI 1.52-2.78); male sex (aOR 0.61, 95% CI 0.49-0.77); severe brain injury (aOR 1.60, 95% CI 1.10-2.32); and bronchopulmonary dysplasia (aOR 2.22, 95% CI 1.67-2.94).Conclusions: Rates of home NG-tube feeding varied widely between Canadian NICUs. Higher gestational age and male sex reduced the odds of discharge home to receive NG-tube feeding; and in contrast small for gestational age, severe brain injury, prolonged duration on mechanical ventilation and bronchopulmonary dysplasia increased the odds.

Objectives: To examine rates and determinants of mother's own milk (MOM) feeding at hospital discharge in a cohort of infants born very preterm within the Canadian Neonatal Network (CNN).Study Design: This was a population-based cohort study of infants born at <33 weeks of gestation and admitted to neonatal intensive care units (NICUs) participating in the CNN between January 1, 2015, and December 31, 2018. We examined the rates and determinants of MOM use at discharge home among the participating NICUs. We used multivariable logistic regression analysis to identify independent determinants of MOM feeding.Results: Among the 6404 infants born very preterm and discharged home during the study period, 4457 (70%) received MOM or MOM supplemented with formula. Rates of MOM feeding at discharge varied from 49% to 87% across NICUs. Determinants associated with MOM feeding at discharge were gestational age 29-32 weeks compared with <26 weeks (aOR 1.56, 95% CI 1.25-1.93), primipara mothers (aOR 2.12, 95% CI 1.86-2.42), maternal diabetes (aOR 0.79, 95% CI 0.66-0.93), and maternal smoking (aOR 0.27, 95% CI 0.19-0.38). Receipt of MOM by day 3 of age was the major predictor of breast milk feeding at discharge (aOR 3.61, 95% CI 3.17-4.12).Conclusions: Approximately two-thirds of infants born very preterm received MOM at hospital discharge, and rates varied across NICUs. Supporting mothers to provide breast milk in the first 3 days after birth may be associated with improved MOM feeding rates at discharge. [ABSTRACT FROM AUTHOR] more...
