A Quality Improvement Initiative to Reduce Necrotizing Enterocolitis in Very Preterm Infants.

OBJECTIVE: To reduce the incidence of necrotizing enterocolitis (NEC) among very preterm infants in the Calgary Health Region to ≤2% within 2 years. METHODS: A multidisciplinary team developed key drivers for NEC. Targeted interventions included strategies to increase mothers' own milk (MOM), improve compliance with feeding regimens, standardize management of feeding intolerance, prevent intestinal microbial aberrations, and feed conservatively during blood transfusion and the treatment of patent ductus arteriosus. The outcome measure was NEC (≥ stage 2). Changes in NEC rates were examined among racial and ethnic groups. Process measures included MOM feeding at discharge, the difference between actual and expected time to reach full feeds, lowest hemoglobin, and the duration of empirical antibiotics. Growth, the rate of blood transfusion, and the duration of parenteral nutrition were balancing measures. The preintervention, intervention, and sustainment periods were January 2013 to June 2016, July 2016 to December 2018, and December 2018 to December 2021, respectively. RESULTS: We included 2787 infants born at ≤326/7 weeks' gestation (1105 preintervention, 763 during intervention, and 919 in sustainment). NEC decreased from 5.6% to 1.9%. Process measures indicated increased MOM feeding at discharge, improved compliance with feeding regimens, increased lowest hemoglobin levels, and shorter durations of empirical antibiotics. Balancing measures revealed improved weight Z-scores, shorter durations on parenteral nutrition, and increased rates of blood transfusion. CONCLUSIONS: Quality improvement initiatives to increase MOM, improve compliance with feeding regimens, feed conservatively during blood transfusion and treatment of patent ductus arteriosus, and prevent intestinal microbial aberrations were associated with reduced NEC.

Hindmilk as a Rescue Therapy in Very Preterm Infants with Suboptimal Growth Velocity.

Despite advances in neonatal nutrition, very preterm infants remain at increased risk of extrauterine growth faltering. This prospective study aimed to examine the effect of hindmilk, the milk at the end of a breast expression session, on growth and plasma fatty acids (FAs) of infants born <30 weeks' gestation who had been on full enteral feeds for ≥2 weeks and had a weight gain of <15 g/kg/day despite optimizing energy and protein intakes. Weight and plasma FAs were assessed before and two weeks after feeding hindmilk. Growth anthropometrics were assessed weekly for four weeks. Paired t-tests and multiple linear regression were used for statistical analyses of data from 34 infants and their 29 mothers. There was a significant increase in weight gain in the two weeks after feeding hindmilk (MD 3.9, 95%CI 1.2-6.5 g/kg/day). Weight Z-scores were larger at two weeks (MD 0.61, 95%CI 0.02-1.20) and onwards. Head circumference Z-scores were larger at three weeks (MD 0.83, 95%CI 0.20-1.47) and onwards. Plasma linoleic acid (LA) and α-linolenic acid (ALA) increased after feeding hindmilk. In conclusion, hindmilk may improve weight and head growth and increase LA and ALA in very preterm infants with suboptimal growth. A large randomized controlled trial is required to examine and validate the potential benefits of hindmilk.

Combining Evidence-Based Interventions to Support Mental Health in Neonatal Intensive Care Families.

Families of infants requiring admission and care within the NICU experience a multitude of overwhelming stressors and challenges related to the severity and duration of their infant's illness and their unique life circumstances. These stressful experiences, traumas, and challenges can have long-term physical, emotional, financial, and psychological consequences for both the infant admitted to the NICU and their family. Combining evidence-based research and practices, family-centered care, enhanced multidisciplinary collaboration and communication, and mental health education into a multifaceted evidence-based mental health intervention will create opportunities for improved parental role attainment and infant attachment. The implementation of a standardized approach to providing comprehensive mental health support for families with infants needing NICU care will lower anxiety, depression, and post-traumatic stress disorder rates leading to optimized family health and wellness and improved neurodevelopmental outcomes for their infants.

Rates and Determinants of Mother's Own Milk Feeding in Infants Born Very Preterm.

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.
