Prevalence and Trends in Donor Milk Use in the Well-Baby Nursery: A Survey of Northeast United States Birth Hospitals

Perspective: Supporting Maternal Efforts to Provide Optimal Infant Nutrition in the Post-Partum Setting

Supporting optimal newborn nutrition and the positive maternal-infant relationship while encouraging safe sleep practices are essential components of maternal and newborn care in the hospital setting following birth. Breastfeeding is widely recognized as the best practice to support the nutritional needs and well-being of the infant, and recommendations have been developed by the WHO, the American Academy of Pediatrics (AAP), and the United States Centers for Disease Control to encourage and successfully support breastfeeding efforts before hospital discharge. The 10 Steps to Successful Breastfeeding, developed and promoted by the WHO, form the basis of the Baby-Friendly Hospital Initiative (BFHI) and have become the international framework for public health initiatives to promote breastfeeding. An evaluation of hospital performance implementing the 10 steps through the process of "Baby-Friendly Designation" (BFD) has been suggested by many breastfeeding advocates as the optimal pathway to attain the goals of the BFHI. However, the WHO has recognized that BFD may not be an appropriate goal in all settings, and indicated, as part of their updated 2018 guidance, that "facilities may make changes in their policies and procedures to obtain the designation, but these changes are not always sustainable, especially when there are no regular monitoring systems in place." In addition, unintended associated issues regarding newborn safety and maternal dissatisfaction with some of the 10 steps have emerged. This perspective discusses the challenges faced by hospitals attempting to implement the BFHI 10 steps and suggests potential solutions to make progress in those efforts with or without BFD and also the efforts needed to support formula feedings when appropriate.

Mother's Own Milk Versus Donor Human Milk: What's the Difference?

Mother's own milk (MOM) is known to decrease complications in preterm infants and when unavailable, it is recommended that preterm very low-birth weight infants be fed donor human milk (DHM). Due to the pasteurization, processing, and lactation stage of donors, DHM does not contain the same nutritional, immunologic, and microbial components as MOM. This review summarizes the differences between MOM and DHM, the potential effects on health outcomes, and the clinical implications of these differences. Finally, implications for research and clinical practice are discussed.

Facilitators and Barriers of Human Milk Donation

PURPOSE

The purpose of this study is to examine perceptions and experiences of women who donate human milk and highlight various aspects of the breast milk donation process.

STUDY DESIGN

A cross-sectional descriptive study.

METHODS

An online survey was conducted with a convenience sample of women who donated milk at several milk banks in the United States. A questionnaire of 36 closed and open-ended items were developed and validated by the research team. Descriptive statistics and content analysis were used. Semantic content analysis involved three procedures: coding, categorizing text units, and refining the identified themes.

RESULTS

A total of 236 women who donated breast milk completed the questionnaire. Mean age of participants was 32.7±4.27 and 89.40% were non-Hispanic White women with a bachelor's degree (32.20%) or graduate degree (54.70%). Most participants were women who actively donated breast milk, ranging from one to four times. Two themes, facilitators and barriers of milk donation, were identified. Facilitators to milk donation included attitudes toward milk donation, commitment for donating, motivation in donating, and support. Barriers included personal factors, environment, milk donor process, and psychosocial factors.

CLINICAL IMPLICATIONS

Nurses, health care providers, and lactation professionals should educate women about milk donation resources and opportunities. Strategies to increase awareness about milk donation among underrepresented groups such as women of color are highly recommended. Future research is needed to further explore specific factors that increase milk donation awareness and minimize barriers to potential donors.

Supporting Families Facing Lactation Anaphylaxis: A Case Report

Lactation anaphylaxis is a rare condition that may occur consequent to breastfeeding. Early identification and management of symptoms is paramount to the physical well-being of the birthing person. Supporting newborn feeding goals is also a key component of care. In cases in which the birthing person wants to exclusively feed human milk, planning should include streamlined access to donor milk. Clear communication between health care providers and developing systems to access donor milk for parental indications may help address barriers.

Recommendations for the establishment and operation of a donor human milk bank

In Europe, an increasing number of human milk banks (HMBs) collect donor human milk to feed preterm infants when their mother's milk is not available or not enough. Moreover, donor milk is a bridge to breastfeeding, with positive clinical and psychological advantages for both mother and infant. Italy, with 41 HMBs actively operating in 2022, has the highest number of HMBs in Europe. The process of human milk donation is complex, so activity of HMBs must be regulated according to well-established rules. The present recommendations have been prepared as a tool to standardize the organization, management, and procedures of HMBs operating in Italy and to determine the minimal essential requirements to establish new HMBs. This article covers all the aspects of human milk donation and human milk banking, including general recommendations, donor recruitment and screening, expression, handling and storage of donor human milk, milk screening, and milk treatment (pasteurization). A pragmatic approach was taken to drafting the recommendations. Items for which there was consensus or robust published evidence on which to base recommendations were included. When there were differences that could not be resolved by reference to published research, a statement of explanation based on the expert opinion of the authors (all members of the Italian Association of Human Milk Banks) was included. Implementation of these recommendations can contribute to promotion of breastfeeding.

Relationship Between Maternal COVID-19 Infection and In-Hospital Exclusive Breastfeeding for Term Newborns

Objective

To evaluate the relationship between maternal COVID-19 infection and the odds of in-hospital exclusive breastfeeding for term newborns.

Design

Retrospective descriptive quantitative.

Setting

A large, urban hospital with more than 6,000 births annually.

Sample

Term newborns born between March 1, 2020, and March 31, 2021 (N = 6,151).

Methods

We retrospectively extracted data from electronic health records to evaluate the relationship of maternal COVID-19 infection with the odds of in-hospital exclusive breastfeeding using univariate analysis and logistic regression models. The covariates included insurance type, race/ethnicity, glucose gel administration, length of stay, newborn gestational age, newborn birth weight, and maternal COVID-19 infection.

Results

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding (p = .138) after adjustment for covariates in the logistic regression model. However, when newborns who received pasteurized donor human milk supplementation were excluded from the logistic regression model, maternal COVID-19 infection significantly decreased the odds of in-hospital exclusive breastfeeding (p = .043).

Conclusion

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding when newborns received donor human milk supplementation. Access to donor human milk for supplementation for term newborns may protect the odds of in-hospital exclusive breastfeeding.

Clinical Characteristics and Breastfeeding Outcomes in Term Dyads Following In-Hospital Supplementation with Pasteurized Donor Human Milk or Formula

Background: Pasteurized donor human milk (PDHM) supplementation for healthy infants is an emerging practice. Little is known about demographics or breastfeeding outcomes for dyads whose mothers choose PDHM versus formula. Research Aims: To identify relationships between in-hospital supplementation choice and (1) dyad characteristics and breastfeeding intent, and (2) breastfeeding outcomes at 1 month. Materials and Methods: This exploratory prospective cohort study surveyed healthy dyads requiring medically indicated supplementation. Participants completed questionnaires including demographics, breastfeeding intent, and self-efficacy during hospitalization, and self-efficacy and lactation outcomes at 1 month. Results: Of 39 participants, 24 (62%) supplemented with formula and 15 (38%) with PDHM. Formula dyads were more likely than PDHM dyads to have a delivery body mass index (BMI) ≥30 kg/m² (58% versus 20%, p = 0.02), and less likely to have attained greater than a college degree (33% versus 7%, p = 0.02); formula dyads also reported lower breastfeeding intent scores (12.0 versus 15.5, p = 0.002). Breastfeeding self-efficacy scores were similar but decreased for both groups over 1 month. At 1 month, mothers who chose formula were more likely to continue to provide breast milk to their infants (84% versus 72%). Direct breastfeeding rates were similar (72% versus 68%); of participants directly breastfeeding at 1 month, PDHM dyads were 1.5 times more likely to provide maternal expressed milk. Conclusions: Differences in maternal education, BMI, and breastfeeding intent were found between feeding groups. Results suggest an association between PDHM choice and initial breastfeeding intent and breastfeeding self-efficacy and provision of maternal expressed milk at 1 month.

Supplementation-based hypoglycemia guidelines including donor breast milk reduce NICU admission

OBJECTIVE

To study the effects of a supplementation-based hypoglycemia guideline including donor (DM) on NICU admission, exclusive breastfeeding, and blood glucose concentrations in infants at-risk for neonatal hypoglycemia (NH).

PROJECT DESIGN

We integrated DM, feeding supplementation, and reduced frequency of blood glucose testing into an NH bundle for term and late-preterm newborns. We then examined NICU admission rates and rates of exclusive breastfeeding at discharge.

RESULTS

NICU admission rates were reduced to 6% (-10%). Exclusive breastfeeding rates increased to 55% (+22%). Median cost of DM utilization was $13.73 per patient with an average volume of 50.8 ml/infant. DM supplementation resulted in similar times to last hypoglycemic episode and greater increases in blood glucose compared to expressed breast milk or breastfeeding alone (+9.6 mg/dL, p < 0.05).

CONCLUSIONS

A supplementation-based hypoglycemia guideline including donor milk may be an effective way to reduce NICU admissions for asymptomatic hypoglycemia and support mothers in achieving breastfeeding goals.

Human Milk for the Term Newborn

Human milk provides optimal nutrition for term newborns, but the prevalence of its use is below target, and risks have been identified. Infants of black mothers as well as term newborns admitted to the neonatal intensive care unit are at risk for not receiving human milk. To improve human milk intake, multiple individual-level interventions have been shown to be effective, but some popular system-level interventions are ineffective or harmful. Expressed milk and donor milk may be less beneficial than direct breastfeeding. Nuanced public policies can help support lactation while promoting individual choice and equity.

The Current State of Donor Human Milk Use and Practice

Human milk contains nutrients and immune factors that promote health and growth of an infant. Donor human milk is recommended as the best alternative for infants whose mothers' breast milk is unavailable. This article describes the current status of donor human milk practice and suggests the areas of educational and research needs. Articles published in the last 10 years were reviewed, and findings were summarized under 4 themes: (1) women's knowledge and concerns about donor human milk use, (2) hospital practices, (3) cost-effectiveness, and (4) access and affordability of donor human milk. Women were concerned about donor human milk contamination, disease transmission, cost, and access to bank donor human milk, due to lack of knowledge and awareness of donor human milk benefits and its processing procedures. The absence of health care providers' support for donor human milk adds to the confusion. There is a rising trend of donor human milk use in hospitals for both healthy and vulnerable newborns and infants with varying policies on screening for donor human milk use, cost coverage, or consent procedure. However, a shortage of safe and affordable donor human milk is a barrier to its adoption. A standardized guideline is needed for hospitals regarding donor human milk implementation and cost coverage. Education programs for health care providers are needed to improve knowledge and understanding of donor human milk benefits and safety to provide guidance to parents. It is crucial to develop legislation expanding insurance coverage to achieve donor human milk equity and optimizing long-term human milk diet outcomes.

Factors Associated with the Use of Pasteurized Donor Milk for Healthy Newborns: Experience from the First Human Milk Bank in Vietnam

Background: Pasteurized donor milk (PDM) is typically prescribed to preterm or low birthweight newborns when their mother’s own milk is unavailable. In surplus, PDM is prescribed to meet the nutritional needs of healthy newborns in the first few days of life. However, its overuse can undermine efforts to promote and support breastfeeding, waste resources, and reduce the availability of PDM for at-risk newborns. We conducted this study to examine factors associated with the prescription and prolonged use (>48 h) of privately purchased PDM to healthy newborns. Methods: Prospective observational study of 2440 mothers of healthy, term, and normal birthweight newborns born at Da Nang Hospital for Women and Children between April and August 2019. In addition to the descriptive analysis, we performed multiple logistic regressions to examine factors associated with the prescription of PDM (n = 2440) and prolonged PDM use among those who used PDM (n = 566). Results: Twenty-three percent (566/2440) of healthy, term, and birthweight ≥2500 g newborns received PDM and were included in the study. The prevalence of PDM use was higher for cesarean births (OR: 2.05; 95% CI: 1.66, 2.55) and among male newborns (OR: 1.33; 95% CI: 1.09, 1.62), but lower for farmers or workers (vs. other jobs; OR: 0.71; 95% CI: 0.54, 0.93), family income <10 million VND (vs. ≥10 million VND; OR: 0.67; 95% CI: 0.55, 0.82), and duration of skin-to-skin ≥90 min (vs. <90 min; OR: 0.54; 95% CI: 0.39, 0.76). Prolonged PDM use (12.4% of 566 newborns who used PDM) was associated with the mother having a higher socioeconomic status job (professional, small trader or homemaker; OR: 4.00; 95% CI: 1.39, 12.5), being a first-time mother (OR: 3.39; 95% CI: 1.92, 6.01) or having a cesarean birth (OR: 2.09; 95% CI: 1.02, 4.28). Conclusions: The prescription and prolonged use of privately purchased PDM was associated with non-medical factors unrelated to the ability to breastfeed effectively. The findings suggest the need for improved breastfeeding communication, counseling and support skills for health staff, development, and application of strict criteria on PDM use for healthy newborns and better routine monitoring of PDM use over time.

Trends and Dynamics in the First Four Years of Operation of the First Human Milk Bank in Vietnam

Background: Since 1979, the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) have recommended the use of pasteurized human milk from a human milk bank (HMB) to feed low birthweight (LBW) and preterm newborns as the ‘first alternative’ when mothers are unable to provide their own milk. However, they have not issued any guidelines for the safe establishment and operation of an HMB. This gap contributes to the demand for gathering experiences from HMB networks, especially those from lower-middle income countries. To fill this knowledge gap, this study examines the characteristics of donors, donation, pasteurization, and recipients during the first four years of operation in the first HMB in Vietnam. Methods: Data about the donors, donation, pasteurization, and recipients were extracted from the web-based electronic monitoring system of the HMB from 1 February 2017 to 31 January 2021. Results: In the first four years of operation there were 433 donors who donated 7642 L of milk (66% from the community) with an increased trend in the amount of donated milk, donation duration, and average amount of milk donated by a donor. Approximately 98% of the donated milk was pasteurized, and 82% passed both pre- and post-pasteurization tests. Although the pass rate tended to increase with time, a few dips occurred. Of 16,235 newborns who received pasteurized donor milk, two thirds were in the postnatal wards. The main reason for the prescription of pasteurized donor milk was insufficient mothers’ own milk in the first few days after birth. There was a decreased trend in the amount and duration of using pasteurized donor milk in both postnatal wards and the neonatal unit. Conclusions: The HMB has operated efficiently in the previous four years, even during the COVID-19 pandemic, to serve vulnerable newborns. Ongoing evidence-based adjustments helped to improve the operation to recruit suitable donors, to increase the access to and quality of raw donor milk, to improve the pasteurization process, and to meet the need of more newborns.

An Alternative to Mother's Own Milk: Maternal Awareness of Donor Human Milk and Milk Banks

BACKGROUND

The use of donor human milk is rising. Maternal awareness of donor human milk use, milk donation, and milk banks has not been well described in the United States.

RESEARCH AIMS

To explore maternal experience, knowledge, and attitudes regarding donor human milk use and milk donation. We also assessed counseling by medical providers about donor human milk use and donation.

METHODS

A cross-sectional prospective survey design was used in this study. We anonymously surveyed mothers (N = 73) attending the 1 to 2-week well newborn appointment. Analyses were completed using one-way ANOVA and logistic regression.

RESULTS

Participants' infants primarily received their own mother's milk (87%, n = 61). No infants received donor human milk, but 4% (n = 3) of participants donated milk. The majority of participants had positive responses to attitudinal statements about donor milk. When presented with a hypothetical scenario, participants chose formula (89%, n = 59) over donor human milk (11%, n = 7) for their infant. Moreover, if donor human milk was the only option available, they chose donor human milk from a relative or friend (60%, n = 40) over a milk bank (40%, n = 26). Medical providers had discussed donor human milk use or donation with 4% (n = 3) of participants.

CONCLUSIONS

The majority of participants previously had minimal experience using donor human milk and limited knowledge regarding donor human milk and milk banks. According to participants, medical providers did not routinely discuss milk donation and the role of donor human milk with families.

Use of donor human milk in nonhospitalized infants: An infant growth study

When mother's own milk (MOM) is unavailable or insufficient, donor human milk (DHM) is recommended as the next best alternative for low birthweight infants. DHM use for healthy, term infants is increasing, but evidence for growth and tolerability is limited. This retrospective study evaluated growth in term infants in the community who received DHM from a UK milk bank. Mothers of infants receiving DHM between 2017 and 2019 were contacted (n = 49), and 31 (63.2%) agreed to participate. Fourteen infants received DHM as a supplement to other feeds (MOM and/or infant formula) and 17 were exclusively fed DHM where breastfeeding was impossible (range: 3–6 weeks). Growth was assessed by deriving z‐scores using the WHO standard for infant growth and compared with 200 exclusively breastfed infants. Multivariate regression analysis revealed no feeding method‐specific association between z‐score and age, nor between weight and age, suggesting that z‐scores and growth velocity were not affected by feeding exclusive MOM, supplemental DHM or exclusive DHM. DHM was well‐tolerated with no adverse events that led to early cessation. After receiving supplemental DHM group, 63% of infants whose mothers had no physical barrier to breastfeeding (5/8 infants) were exclusively breastfed. This novel study reports adequate growth outcomes of healthy nonhospitalized infants receiving DHM, either as the sole milk source or supplement. Prospective studies are needed to confirm whether DHM is a suitable feeding alternative for term infants in the community, optimal durations, as well as the impact of DHM availability on breastfeeding rates and maternal mental health.

DHM recipients were compared with the who infant growth standard (World Health Organization, 2020) by deriving z‐scores. The WHO Anthro Macro (World Health Organization, 2011 ) was used to calculate weight‐for‐age, length‐for‐age and head circumference‐for‐age z‐scores; z‐scores are the standard deviation of an infant's anthropometric measurements when compared with the WHO standard for infant growth and are gender and age specific.

Donor Human Milk Use in Populations Other than the Preterm Infant: A Systematic Scoping Review

Introduction: Exclusive breastfeeding is recommended for an infant's first 6 months of life. If unable to breastfeed, expressed breast milk, including donor human milk (DHM), is recommended for optimal nutrition. Benefits of DHM in preterm infants have been established by extensive research. However, less is known about DHM use in other populations. Objective: To conduct a scoping review of the literature regarding DHM use in populations other than preterm infants. Materials and Methods: PubMed and Clinicaltrials.gov were used to search for articles and clinical trials published between January 1, 2000 and February 29, 2020. In total, 182 articles and reports were identified and screened by 2 independent reviewers. Results: Twenty-six articles met inclusion criteria and were reviewed. Studies were mostly observational in design and included infants born >35 weeks gestational age with health risks (9/26) and healthy infants (14/26). Most studies in infants with health risks (7/9) investigated clinical outcomes, with small, observational studies suggesting potential improvements in feeding tolerance and gastrointestinal health. Regarding healthy infants, no studies addressed growth, only one study measured clinical outcomes, and findings related to breastfeeding outcomes were conflicting. Over half of the studies reviewed (15/26) were not designed to establish a potential relationship between DHM use and relevant health-related outcomes. Conclusion: The current evidence of DHM use in populations other than preterm infants is limited by lack of direct health measures and infrequent use of randomized trials. More research is warranted to investigate clinical, growth, and breastfeeding outcomes.

National Prevalence of Donor Milk Use Among Level 1 Nurseries

BACKGROUND AND OBJECTIVES

Donor milk use has increased among very preterm infants because of mounting evidence of health benefits; however, the extent that donor milk is used among healthy term infants in level 1 nurseries is unclear. We aimed to determine (1) national prevalence of and (2) hospital factors associated with donor milk use in level 1 nurseries.

METHODS

Among 3040 US birthing hospitals, we randomly selected hospitals from each of 4 US regions (119 in northeast, 120 in Midwest, 116 in west, and 103 in south) for a total of 458 hospitals. We surveyed the nursing leaders of these hospitals from October to December 2017 regarding routine use of donor milk in the level 1 nursery (yes or no). To estimate national prevalence, we weighted responses according to the number of birthing hospitals within each region. We examined relationships between routine donor milk use in the level 1 nursery and hospital characteristics using multivariable logistic regression.

RESULTS

In total, 214 of 458 (47%) nursing leaders responded. The national prevalence of routine donor milk use in level 1 nurseries was 17.6%. Eighty-five percent of donor milk programs were ≤5 years old. Donor milk use occurred more often in hospitals with ≥1500 annual births (41.7%), compared to ≤500 annual births (6.3%) (adjusted odds ratio 7.8; 95% confidence interval 1.8-34.4), and in the west (30.9%), compared to the northeast (10.5%) (adjusted odds ratio 4.1; 95% confidence interval [1.1-14.9]).

CONCLUSIONS

Although there is limited evidence to support donor milk for healthy infants in the nursery, nearly one-fifth of level 1 US nurseries routinely used donor milk in 2017.

Supplementation Practices and Donor Milk Use in US Well-Newborn Nurseries

BACKGROUND AND OBJECTIVES

Guidelines encourage exclusive breastfeeding for healthy newborns but lack specificity regarding criteria for medically indicated supplementation, including type, timing, and best practices. We set out to describe practice patterns and provider perspectives regarding medically indicated supplementation of breastfeeding newborns across the United States.

METHODS

From 2017 to 2018, we surveyed the Better Outcomes through Research for Newborns representative from each Better Outcomes through Research for Newborns hospital regarding practices related to medically indicated supplementation. We used descriptive statistics to compare practices between subgroups defined by breastfeeding prevalence and used qualitative methods and an inductive approach to describe provider opinions.

RESULTS

Of 96 providers representing discrete hospitals eligible for the study, 71 participated (74% response rate). Practices related to criteria for supplementation and pumping and to type and caloric density of supplements varied widely between hospitals, especially for late preterm infants, whereas practices related to lactation consultant availability and hand expression education were more consistent. The most commonly reported criterion for initiating supplementation was weight loss of ≥10% from birth weight, and bottle-feeding was the most commonly reported method; however, practices varied widely. Donor milk use was reported at 20 (44%) hospitals with ≥81% breastfeeding initiation and 1 (4%) hospital with <80% breastfeeding initiation (P = .001).

CONCLUSIONS

Strategies related to supplementation vary among US hospitals. Donor milk availability is concentrated in hospitals with the highest prevalence of breastfeeding. Implementation of evidence-based management of supplementation among US hospitals has the potential to improve the care of term and late preterm newborns.

Implementation of the Reimbursement Cost of Human-Milk-Based Neonatal Therapy in Polish Health Care Service : Practical and Ethical Background

BACKGROUND

A human-milk-based diet is the best option for nutritional therapy for preterm and/or sick newborns.

RESEARCH AIM

The study aims were to restructure the reimbursement rates to hospitals in Poland for infants' tube feedings to favor the use of donor human milk over formula for newborns who required supplementation of expressed mother's milk and evaluate the results of the financing change during the first year of implementation (2018).

METHODS

Financial data from hospitals were collected (2015-2016) by the Human Milk Bank Foundation using a data sheet designed by the Agency for Health Technology Assessment and Tariff System. We used data to restructure the reimbursement rates to hospitals for infants' tube feedings and implemented the changes in late 2017. The National Health Fund was requested to share reported data in 2018 concerning tube feeding services.

RESULTS

More than half (61%) of NICUs introduced human milk tube feeding for newborns. It was provided to participants (N = 5,530), most frequently to seriously ill preterm infants (66.6%). Of these infants, 2,323 were fed donor human milk. Only 1,925 newborns received formula tube feeding. However, there were large differences in frequency of services reported among various parts of the country.

CONCLUSIONS

Based on our knowledge, Poland is the only European country where the reimbursement cost for human-milk-based nutritional therapy has been implemented in a manner intended to increase the quality of health care services for preterm newborns. Equal reimbursement for expressed mother's milk and donor milk did not appear to cause overuse of donor milk based on our analysis of the 2018 data.

The impact on the exclusive breastfeeding rate at 6 months of life of introducing supplementary donor milk into the level 1 newborn nursery

OBJECTIVES

This study explored whether donor-milk supplementation increases breastfeeding exclusivity at 6 months of life. In 10/2015, we implemented donor milk for breastfed newborns who needed nutritional supplements for hypoglycemia, hyperbilirubinemia, and >8% weight loss at 40 h of life.

STUDY DESIGN

We conducted a retrospective chart review on 122 qualified neonates admitted to newborn nursery at University of Florida Jacksonville 4 months before donor-milk implementation and 6 months after.

RESULTS

73 (60%) of the neonates received formula and 49 (40%) received donor milk. 39 (54%) in the formula group and 33 (46%) in the donor-milk group were surveyed after 6 months of life. Multivariate logistic regression showed that newborns who received donor milk had five times greater odds of being exclusively breastfed at 6 months of life.

CONCLUSIONS

Donor milk as feeding supplementation for newborns is associated with increased exclusive breastfeeding at 6 months of life.

Clinical and Sociodemographic Factors Associated With Human Donor Milk Supplementation in Term Newborns

OBJECTIVES

To identify differences between healthy term newborns supplemented with human donor milk (HDM) and those supplemented with infant formula. We hypothesized that sociodemographic and clinical distinctions exist between newborns receiving different milk types.

METHODS

This retrospective study included term newborns admitted to the postpartum unit between March 2017 and April 2019 with ≥1 supplemental feeding with HDM or formula for indications other than hypoglycemia. Maternal and newborn data were abstracted from the electronic medical record.

RESULTS

Five hundred eighty-four dyads met inclusion criteria. More newborns received supplementation with formula than with HDM (57.7% vs 42.3%; P < .001). Infants undergoing phototherapy who required supplementation were more likely to receive HDM (P < .001). Newborns born to white and non-Hispanic mothers were more likely to receive HDM than those born to African American (adjusted odds ratio [aOR] 5.6; P = .007), Hispanic (aOR 3.0; P = .001), or Asian American mothers (aOR 2.7; P = .007). Newborns born to primiparous women (aOR 1.6; P = .03), those born to women with private insurance (aOR 3.7; P < .001), and those born via cesarean delivery (aOR 2.0; P < .001) were more likely to receive HDM. HDM use was more likely in primary English- or Spanish-speaking households (aOR 8.5; P = .009). Newborns receiving their first supplemental feeding during the day (aOR 1.9; P = .001) were more likely to be supplemented with HDM.

CONCLUSIONS

There are clinical and sociodemographic differences between healthy term newborns supplemented with HDM and formula. These findings reveal that there are disparities in current supplementation practices for healthy newborns.

Prevalence and predictors of donor milk programs among U.S. advanced neonatal care facilities

OBJECTIVE

(1) Determine national prevalence and predictors of donor milk programs among levels 2-4 advanced neonatal care facilities; (2) describe characteristics of donor milk programs.

STUDY DESIGN

We randomly selected 120 U.S. hospitals with levels 2-4 advanced neonatal care facilities among each of four U.S. regions and surveyed the medical directors from July 2017 to November 2017 regarding donor milk use. We weighted responses according to the number of birthing hospitals in each region.

RESULTS

Response rate was 213/480 (44%). Twenty-eight percent of level 2 and 88% of levels 3 and 4 neonatal care facilities had donor milk programs. Donor milk programs occurred more often in the South vs. Northeast (aOR 3.7 [1.1, 12.5] and less often in safety-net hospitals (≥75% Medicaid patients) vs. nonsafety-net hospitals (aOR 0.3 [0.1, 0.8]).

CONCLUSION

In 2017, the vast majority of levels 3 and 4 neonatal care facilities had donor milk programs but disparities existed according to the safety-net hospital status and region.

Human Milk Oligosaccharides Differently Modulate Goblet Cells Under Homeostatic, Proinflammatory Conditions and ER Stress

SCOPE

Human milk oligosaccharides (hMOs) have beneficial effects on intestinal barrier function, but the mechanisms of action are not well understood. Here, the effects of hMOs on goblet cells, which indicate that some hMOs may enhance mucus barrier function through direct modulation of goblet cell function, are studied.

METHODS AND RESULTS

The modulatory effects of 2'-fucosyllactose (2'-FL), 3-fucosyllactose (3-FL), lacto-N-triaose II (LNT2), and galacto-oligosaccharides (GOS) on the expression of goblet cell secretory related genes MUC2, TFF3, and RETNLB, and the Golgi-sulfotransferase genes CHST5 and GAL3ST2 of LS174T are determined by real-time quantitative RT-PCR. 3-FL, LNT2, and GOS-modulated LS174T gene expression profiles in a dose- and time-dependent manner. In addition, the upregulation of MUC2 is confirmed by immunofluorescence staining. Effects of 2'-FL, 3-FL, LNT2, and GOS on gene transcription of LS174T are also assessed during exposure to TNF-α, IL-13, or tunicamycin. During TNF-α challenge, 3-FL and LNT2 enhance MUC2 and TFF3 gene expression. After IL-13 exposure, 2'-FL, 3-FL, and LNT2 all show upregulating effects on MUC2; 3-FL and LNT2 also enhance TFF3 expression. LNT2 significantly reverses Tm-induced downregulation of TFF3, RETNLB, and CHST5.

CONCLUSION

The findings indicate that hMOs may enhance mucus barrier function through direct modulation of intestinal goblet cells. Effects are structure- and stressor-dependent.

Racial and Ethnic Disparities in Human Milk Intake at Neonatal Intensive Care Unit Discharge among Very Low Birth Weight Infants in California

OBJECTIVES

To examine how infant and maternal factors, hospital factors, and neighborhood-level factors impact or modify racial/ethnic disparities in human milk intake at hospital discharge among very low birth weight infants.

STUDY DESIGN

We studied 14 422 infants from 119 California Perinatal Quality Care Collaborative neonatal intensive care units born from 2008 to 2011. Maternal addresses were linked to 2010 census tract data, representing neighborhoods. We tested for associations with receiving no human milk at discharge, using multilevel cross-classified models.

RESULTS

Compared with non-Hispanic whites, the adjusted odds of no human milk at discharge was higher among non-Hispanic blacks (aOR 1.33 [1.16-1.53]) and lower among Hispanics (aOR 0.83 [0.74-0.93]). Compared with infants of more educated white mothers, infants of less educated white, black, and Asian mothers had higher odds of no human milk at discharge, and infants of Hispanic mothers of all educational levels had similar odds as infants of more educated white mothers. Country of birth and neighborhood socioeconomic was also associated with disparities in human milk intake at discharge.

CONCLUSIONS

Non-Hispanic blacks had the highest and Hispanic infants the lowest odds of no human milk at discharge. Maternal education and country of birth were the biggest drivers of disparities in human milk intake, suggesting the need for targeted approaches of breastfeeding support.

Disparities in Donor Human Milk Supplementation Among Well Newborns

BACKGROUND

Donor human milk supplementation for healthy newborns has increased. Racial-ethnic disparities in supplementation have been described in the neonatal intensive care unit but not in the well newborn setting.

RESEARCH AIM

The aim of this study was to identify maternal characteristics associated with donor human milk versus formula supplementation in the well newborn unit.

METHODS

This retrospective cohort study includes dyads of well newborns and their mothers (N = 678) who breastfed and supplemented with formula (n = 372) or donor human milk (n = 306) during the birth hospitalization at a single hospital in the midwestern United States. Maternal characteristics and infant feeding type were extracted from medical records. Chi-square and logistic regression were used to examine associations between maternal characteristics and feeding type.

RESULTS

Nonwhite women were less likely to use donor human milk. Compared to non-Hispanic white women, the largest disparity was with Hispanic (adjusted odds ratio [OR] = 0.28, 95% CI [0.12, 0.65]), then non-Hispanic black (adjusted OR = 0.32, 95% CI [0.13, 0.76]) and Asian women (adjusted OR = 0.34, 95% CI [0.16, 0.74]). Lower donor human milk use was associated with primary language other than English and public versus private insurance.

CONCLUSION

The goal of improving public health through breastfeeding promotion may be inhibited without targeting donor human milk programs to these groups. Identifying the drivers of these disparities is necessary to inform person-centered interventions that address the needs of women with diverse backgrounds.

Donor Milk Policies for Level 1 Newborn Care: A Descriptive Analysis

Background and Objectives: Providing pasteurized donor human milk (DHM) to healthy newborns is an emerging practice. The content of hospital policies that govern this practice is unknown. Materials and Methods: We collected policies from 15 Northeast U.S. hospitals through (1) a 2017 survey on DHM use and (2) an e-mail listserv of levels 1 and 2 newborn care staff maintained by a regional milk bank. Two authors reviewed each policy and identified how they addressed three predetermined themes: who is eligible to receive DHM, how DHM is used and described, and how lactation is supported. Responses were compared, discussed, and reconciled. Level 1 newborn care was defined as basic care for healthy newborns ≥35 weeks' gestation. Results: Thirteen of 15 policies stated criteria for DHM eligibility, most commonly as a bridge until mother's supply comes in (73%) or for infant medical conditions (67%). All required consent for DHM. Most did not limit number of days infants could receive DHM (60%). Nine specified that DHM be discarded 24 hours after thaw, whereas five recommended discarding at 48 hours. Although many (53%) policies endorsed human milk as the preferred diet for newborns, only 27% specifically endorsed DHM as the preferred supplementation type. Parent education (73%) was emphasized, but few (27%) discussed the importance of establishing mother's milk supply. Conclusions: Many DHM policies address eligibility criteria for receiving DHM and show how to provide DHM, but few address how to support lactation while DHM is provided, which may be crucial for optimizing long-term breastfeeding outcomes.

Donated human milk use and subsequent feeding pattern in neonatal units

Background

Donated human milk (DHM) is a safe alternative in the absence of mother’s own milk (MOM); however, specific clinical indications for DHM use and its impact on subsequent feeding practice remain unclear. We aimed to audit local DHM use and explore the impact of the introduction of DHM as the first enteral feed on subsequent MOM availability.

Methods

We retrospectively audited DHM recipients nursed in Royal Hospital for Children, Glasgow from 2014 to 2016 against local guidelines. Data were collected from an operational electronic database. Descriptive data analysis was performed to describe DHM use. To explore the association between the first human milk feed with subsequent MOM availability Kruskal Wallis test was used. Adjustments for confounding variables were performed using analysis of variance (ANOVA).

Results

A total of 165 recipients of DHM (5.3% of all admission to RHC) were identified. The majority of recipients (69%) were born < 32 weeks of gestation. The main indication for DHM was prematurity, other indications included congenital anomalies of bowel and heart. The local guideline was adhered to in 87% of cases. The median interquartile range (IQR) at DHM introduction was 6 days (3, 17) and the duration of use was 12 days (6, 22). In those born < 32 weeks of gestation the type of human milk (DHM and/ or MOM) used as first feed did not influence the subsequent median IQR days of feeding with any MOM [DHM 40 (9, 51); MOM 28 (17, 49), MOM & DHM 17 (10, 26) p value = 0.465] after adjusting for birthweight and length of hospital stay.

Conclusions

In our unit, DHM is mainly used in preterm neonates in accordance with existing local guidance. Using DHM as first milk feed did not affect subsequent MOM availability.

Nurse-Driven Initiative to Increase Exclusive Human Milk Feeding by Using Pasteurized Donor Human Milk to Treat Hypoglycemic Term Neonates

OBJECTIVE

To increase exclusive breastfeeding by offering pasteurized donor human milk (PDHM) to newborns with hypoglycemia.

DESIGN

Quality improvement project.

SETTING/LOCAL PROBLEM

A Baby-Friendly Hospital Initiative-designated urban academic medical center in the northeastern United States serving a diverse population where, by policy, virtually all newborns with hypoglycemia received supplemental infant formula. Approximately 85% of women cared for at this center initiate breastfeeding, but many struggle with exclusive breastfeeding during the hospital stay.

PARTICIPANTS

All staff members in the labor and delivery unit and the mother/baby unit, including registered nurses, unit clerks, patient care technicians, and lactation consultants. Term, breastfed newborns identified as being hypoglycemic per our guidelines were eligible to receive PDHM.

INTERVENTION/MEASUREMENTS

Registered nurses provided education about PDHM to parents of newborns who were hypoglycemic, obtained consent, and initiated the order. We offered PDHM instead of infant formula when mother's own milk was not available in sufficient quantity per our hypoglycemia guidelines. We measured newborns' glucose levels and monitored breastfeeding outcomes, including continued breastfeeding.

RESULTS

During the 4-month trial, 83 newborns were eligible for PDHM. Of those, 76% of parents opted for PDHM rather than formula. Most newborns in both groups were still breastfeeding at discharge, and 53% of those who received PDHM were fed human milk exclusively during their hospital stays.

CONCLUSION

A nurse-driven protocol offering PDHM to otherwise healthy newborns with hypoglycemia is a viable option for increasing exclusive breast milk feeding during the hospital stay.

Effect of Donor Milk Supplementation on Breastfeeding Outcomes in Term Newborns: A Randomized Controlled Trial

BACKGROUND

Pasteurized donor human milk (DHM) use for healthy newborns is increasing; however, no studies have explored its effect on breastfeeding outcomes.

PATIENTS AND METHODS

We enrolled 60 healthy, term breastfeeding newborns with ≥4.5% weight loss in the first 36 hours in a randomized controlled trial. Thirty newborns were randomly assigned to early limited-volume DHM supplementation and 30 newborns to exclusive breastfeeding. Mothers were surveyed at 1 week and 1, 2, and 3 months regarding the mode of infant feeding. Comparing infants randomized to DHM supplementation with those exclusively breastfeeding, there was no significant difference in the proportion using formula at 1 week (21% vs 7%, P = .15), nor in the proportion of any breastfeeding (79% vs 90%, P = .30) or breastfeeding without formula at 3 months (62% vs 77%, P = .27). Conclusion For newborns with ≥4.5% weight loss in the first 36 hours, early limited-volume supplementation with DHM is unlikely to have a significant favorable impact on breastfeeding outcomes.

Nurses' Views on Using Pasteurized Donor Human Milk for Hypoglycemic Term Infants

PURPOSE

The purpose of this study was to explore maternal child nurses' knowledge and beliefs about using pasteurized donor human milk (PDHM) to treat newborns with hypoglycemia. Pasteurized donor human milk has been used for decades in neonatal intensive care units, but its use is relatively new in the well-baby population.

STUDY DESIGN AND METHODS

Focus groups of maternal child nurses were conducted to explore this topic.

RESULTS

Six focus groups that included a total 20 nurses were held. Four themes were identified: 1) nurses presumed safety of PDHM but lacked knowledge, 2) nurses' role as patient-family advocate, 3) nurses' logistical concerns about implementation of PDHM, and 4) nurses lacked clarity on formal milk sharing versus PDHM.

CLINICAL IMPLICATIONS

As the use of PDHM increases for well babies, nurses will need more education about PDHM, its safety profile, its use in breastfeeding support and protection of the infant microbiome, and how PDHM differs from informal milk sharing. Nurses play an important role in helping parents weigh risks and benefits of using PDHM or formula when supplementation is needed during the hospital stay. It is important that nurses feel confident in their own knowledge and ability to address parental concerns so they can advocate for their patients and support parental decision-making.

Donor human milk use in neonatal units: practice and opinions in the Republic of Ireland

BACKGROUND

Over the past decade, where mother's own milk (MOM) is unavailable, the use of donor human milk has become increasingly common in preterm and very low birth weight (VLBW) neonates. Limited literature exists regarding donor human milk practices in neonatal units.

AIMS

To examine practices and opinions regarding use of donor human milk in neonatal units in the Republic of Ireland.

METHODS

Cross-sectional postal survey of all neonatologists and paediatricians working in each of the 19 neonatal units in the Republic of Ireland.

MAIN RESULTS

Eighty-eight paediatricians and neonatologists were surveyed and 44 (50%) replied. Responses were received from 20 (95%) neonatal units, of whom 15 (75%) reported using donor milk. Sixty percent of units had a written donor milk policy however significant variation existed in birth weight and gestational age thresholds for its use. Thirty-eight (86%) of respondents were opposed to the use of donor milk for supplementation of otherwise healthy term neonates. Ten (23%) of respondents believed that supplementation with donor milk compared to formula improves long-term breastfeeding rates. Twenty-two (56%) agreed that the majority of studies supporting the use of donor milk to prevent necrotising enterocolitis in preterm infants were undertaken in the past 15 years.

CONCLUSION

This is the first study to evaluate current practices and opinions regarding donor milk use in the Republic of Ireland and highlights the necessity to develop a national guideline of evidence-based best practice.
