Parents’ views on factors that help or hinder breast milk supply in neonatal care units: systematic review

Objective To synthesise what is known about the parents’ views on factors that help or hinder breast milk supply during their infants’ hospitalisation in neonatal intensive care units (NICU). Methods A systematic search of PubMed, ISI WoK, PsycINFO and SciELO, targeting studies presenting original empirical data that examined parents’ perspectives regarding breast milk supply experiences in NICU, was performed. Based on content analysis, three independent researchers synthesised the findings of seven studies. Categories of facilitators and barriers were identified using quotations stated in the studies: parents’ breast milk supply experience; parents–professionals relationships; characteristics of the NICU; and parents’ social background and expectations. Results The studies, five qualitative and two mixed methods, were published between 1994 and 2011. With heterogeneous study designs, fathers’ perspectives were analysed in one article. Only one study defined breastfeeding. According to parents’ perspectives, successful breast milk supply in NICU depends on coherent and accurate knowledge about its techniques and benefits, reinforcement of mothers’ motivation and alignment between NICUs routines and parents’ needs. Parents perceived issues related to their own current breast milk supply experience, simultaneously, as main facilitators and barriers. Parents–professionals relationship constituted the second group of facilitators, but the fourth of barriers. The characteristics of the NICU were more relevant as a barrier than as a facilitator. Conclusions Although parents’ perspectives are grounded on individual child-focused experiences, their emphasis on learning and motivation guided by short-term goals opens room to the collective intervention of experts. This may facilitate the engagement of mothers, fathers and health professionals on family-centred care.

Use of magnesium sulfate before 32 weeks of gestation: a European population-based cohort study

Objectives The use of magnesium sulfate (MgSO4) in European obstetric units is unknown. We aimed to describe reported policies and actual use of MgSO4 in women delivering before 32 weeks of gestation by indication. Methods We used data from the European Perinatal Intensive Care in Europe (EPICE) population-based cohort study of births before 32 weeks of gestation in 19 regions in 11 European countries. Data were collected from April 2011 to September 2012 from medical records and questionnaires. The study population comprised 720 women with severe pre-eclampsia, eclampsia or HELLP and 3658 without pre-eclampsia delivering from 24 to 31 weeks of gestation in 119 maternity units with 20 or more very preterm deliveries per year. Results Among women with severe pre-eclampsia, eclampsia or HELLP, 255 (35.4%) received MgSO4 before delivery. 41% of units reported use of MgSO4 whenever possible for pre-eclampsia and administered MgSO4 more often than units reporting use sometimes. In women without pre-eclampsia, 95 (2.6%) received MgSO4. 9 units (7.6%) reported using MgSO4 for fetal neuroprotection whenever possible. In these units, the median rate of MgSO4 use for deliveries without severe pre-eclampsia, eclampsia and HELLP was 14.3%. Only 1 unit reported using MgSO4 as a first-line tocolytic. Among women without pre-eclampsia, MgSO4 use was not higher in women hospitalised before delivery for preterm labour. Conclusions Severe pre-eclampsia, eclampsia or HELLP are not treated with MgSO4 as frequently as evidence-based medicine recommends. MgSO4 is seldom used for fetal neuroprotection, and is no longer used for tocolysis. To continuously lower morbidity, greater attention to use of MgSO4 is needed.

The Type of Feeding at Discharge of Very Preterm Infants: Neonatal Intensive Care Units Policies and Practices Make a Difference

Abstract Objective: To assess the influence of neonatal intensive care units (NICUs) on feeding practices at discharge of Portuguese very preterm infants. Materials and Methods: We analyzed data from 580 very preterm infants (<32 gestational weeks) discharged home from NICUs of two Portuguese regions and enrolled during 2011–2012 in Effective Perinatal Intensive Care in Europe population-based cohort. Maternal and infant characteristics were abstracted from medical records, and heads of NICUs provided the units characteristics. Feeding at discharge was classified as exclusive formula, exclusive breast milk or mixed, and differences among NICUs were obtained by comparison with pooled geometric mean odds of all NICUs, using multinomial logistic regression. Median odds ratios (MOR) were calculated to quantify variability among NICUs using multilevel logistic regression. Results: At discharge, 25.2% very preterm infants were exclusively on breast milk, 34.1% exclusively on formula, and 40.7% had mixed feeding...Abstract Objective: To assess the influence of neonatal intensive care units (NICUs) on feeding practices at discharge of Portuguese very preterm infants.

Median odds ratios (MOR) were calculated to quantify variability among NICUs using multilevel logistic regression. RESULTS At discharge, 25.2% very preterm infants were exclusively on breast milk, 34.1% exclusively on formula, and 40.7% had mixed feeding, with a wide variation among NICUs. Exclusive breast milk increased in NICUs that had higher numbers of admissions, provided parents eating facilities, and by having designated members to support mothers who were breastfeeding. The individual NICU odds of mixed versus exclusive formula feeding ranged from 0.36 to 2.07 and for exclusive breast milk versus exclusive formula ranged from 0.16 and 5.11. Adjusting for individual and unit characteristics, heterogeneity across NICUs remained evident, being the MOR 1.33 for mixed feeding and 1.35 for exclusive breast milk. CONCLUSIONS NICUs influence feeding practices independently of individual characteristics, highlighting the importance of institution-based interventions to promote breast milk.

Breastfeeding outcomes in European NICUs: impact of parental visiting policies

Objective The documented benefits of maternal milk for very preterm infants have raised interest in hospital policies that promote breastfeeding. We investigated the hypothesis that more liberal parental policies are associated with increased breastfeeding at discharge from the neonatal unit. Design Prospective area-based cohort study. Setting Neonatal intensive care units (NICUs) in 19 regions of 11 European countries. Patients All very preterm infants discharged alive in participating regions in 2011–2012 after spending >70% of their hospital stay in the same NICU (n=4407). Main outcome measures We assessed four feeding outcomes at hospital discharge: any and exclusive maternal milk feeding, independent of feeding method; any and exclusive direct breastfeeding, defined as sucking at the breast. We computed a neonatal unit Parental Presence Score (PPS) based on policies regarding parental visiting in the intensive care area (range 1–10, with higher values indicating more liberal policies), and we used multivariable multilevel modified Poisson regression analysis to assess the relation between unit PPS and outcomes. Results Policies regarding visiting hours, duration of visits and possibility for parents to stay during medical rounds and spend the night in unit differed within and across countries. After adjustment for potential confounders, infants cared for in units with liberal parental policies (PPS≥7) were about twofold significantly more likely to be discharged with exclusive maternal milk feeding and exclusive direct breastfeeding. Conclusion Unit policies promoting parental presence and involvement in care may increase the likelihood of successful breastfeeding at discharge for very preterm infants.
