Time intervals between pumping did not affect breastmilk protein produced by mothers of preterm infants.

AIM: Few studies investigate factors that might influence the content of expressed breastmilk. This study aims to investigate the influence of the intervals between breastmilk pumping and the time of the day on protein and fat concentration in breastmilk. METHODS: Mothers of very preterm infants in a neonatal ward who expressed more than 400 mL per day were included. Expressed breastmilk was obtained from each mother over 30 h who were pumping at strictly planned and varying intervals: 2, 3, 4 and 6 h. All samples were analysed using infrared transmission spectroscopy. RESULTS: Ten mothers participated at a median of 22 days postpartum. A total of 176 milk samples were analysed, and the average protein and fat concentrations in g/100 mL were 1.1 ± 0.23 and 4.2 ± 1.3, respectively. The time intervals between breast pumping sessions did not impact protein content, but fat content decreased by longer intervals (p < 0.01). The time of the day for milk pumping did not influence the protein or fat content. CONCLUSION: A single milk sample collected after any 2-6 h interval, at any time during the day, represents the protein content in the breastmilk, but not the fat content which decreased with longer intervals.

Skin-to-skin contact after birth: Developing a research and practice guideline.

AIM: Skin-to-skin contact immediately after birth is recognised as an evidence-based best practice and an acknowledged contributor to improved short- and long-term health outcomes including decreased infant mortality. However, the implementation and definition of skin-to-skin contact is inconsistent in both practice and research studies. This project utilised the World Health Organization guideline process to clarify best practice and improve the consistency of application. METHODS: The rigorous guideline development process combines a systematic review with acumen and judgement of experts with a wide range of credentials and experience. RESULTS: The developed guideline received a strong recommendation from the Expert Panel. The result concluded that there was a high level of confidence in the evidence and that the practice is not resource intensive. Research gaps were identified and areas for continued work were delineated. CONCLUSION: The World Health Organization guideline development process reached the conclusion immediate, continuous, uninterrupted skin-to-skin contact should be the standard of care for all mothers and all babies (from 1000 g with experienced staff if assistance is needed), after all modes of birth. Delaying non-essential routine care in favour of uninterrupted skin-to-skin contact after birth has been shown to be safe and allows for the progression of newborns through their instinctive behaviours.

Baseline status regarding compliance with neo-BFHI recommendations in South African neonatal wards: a cross-sectional survey.

BACKGROUND: In 2009, the World Health Organization and the United Nations Children's Fund issued a revised Baby-friendly Hospital Initiative (BFHI) package to encourage all healthcare facilities to promote the advice of exclusive breastfeeding. The scope of the BFHI was expanded to include neonatal units by the Nordic and Quebec Working Group. AIM: To determine the level of compliance with the recommendations outlined in the "Baby-friendly Hospital Initiative for neonatal wards" (Neo-BFHI) in the South African neonatal wards. METHOD: In this cross-sectional survey, the sample included neonatal wards (N = 33) from public and private hospital facilities. Using EasyTrial software, the Neo-BFHI self-assessment questionnaire was utilized to collect the data. The data was transferred to MS Excel (version 15.0.5127.1000) and analysed with the Statistical Package for Social Sciences version 24. RESULTS: The South African median score for Neo-BFHI compliance was 77. Neonatal wards in public hospitals scored higher (85) than those in private hospitals (73). Neonatal wards in hospitals that were accredited Baby-friendly had higher compliance scores than those without accreditation. The country had the highest compliance scores (100, 90) on Guiding Principle 1 (respect towards mothers) and step 5 (breastfeeding support), respectively. However, it scored low (71, 58) on steps 4 (enhancing kangaroo mother care) and 7 (maternal infant "togetherness"), respectively. Level 1 and 2 care facilities scored significantly higher than level 3. CONCLUSION: Although South Africa successfully implemented the Neo-BFHI recommendations, private hospitals had a smaller number of BFHI-accredited facilities and lower compliance than public hospitals. Strategies should be developed to strengthen and improve BFHI accreditation and compliance, particularly in private hospitals.

Nurses' and Physicians' Rationale Behind Clinical Performance and Interpretation of Routine Prefeed Gastric Aspiration in Preterm Infants: A Cross-sectional Study.

This study aims at understanding the rationale behind performing prefeed gastric aspirations in preterm infants, how nurses and physicians interpret the gastric aspiration and variations between them, and illuminating potential barriers for omitting routine prefeed aspiration. Nurses and physicians from all Danish neonatal intensive care units completed a questionnaire. Of 682 participants, the majority (94%) indicated that they routinely performed prefeed aspiration, primarily to check the feeding tube placement (nurses: 88%, physicians: 46%). Nurses feared necrotizing enterocolitis when observing a large gastric residual (GR) volume (31%) and green-stained GR (63%). Fewer nurses relative to physicians had "no worries" related to large volumes (15% vs 34%) or green-stained GR (14% vs 24%, both P < .01). More nurses than physicians intended to pause enteral feeding when observing green-stained GR (31% vs 16%, P < .01) and more nurses were concerned of completely omitting routine gastric aspirations (90% vs 46%, P < .05). The rationale behind the clinical use of GR volume and color as markers of necrotizing enterocolitis and feeding intolerance differs markedly between nurses and physicians in Denmark. If routine prefeed gastric aspiration should be omitted, special focus on information about early signs of necrotizing enterocolitis and methods to check tube placement is needed.

The Baby-friendly Hospital Initiative for neonatal wards. A mini review.

The Baby-friendly Hospital Initiative for Neonatal Wards (Neo-BFHI) is an expansion of the WHO/UNICEF Ten Steps to Successful Breastfeeding to address the needs of infants and families in all levels of neonatal care. The Neo-BFHI includes Three Guiding Principles as basic tenets, Ten Steps to protect, promote and support breastfeeding closely following the original Baby-friendly Hospital Initiative, and adherence to the International Code of Marketing of Breast-milk Substitutes. In 2020, the WHO/UNICEF published recommendations for breastfeeding small, sick and preterm newborns that aligns with the Neo-BFHI. Conclusion: This mini review provides a brief description of the content in the Neo-BFHI.

How to support fathers of preterm infants in early parenthood - An integrative review.

PROBLEM: Preterm birth is a stressful event. Paternal experiences of having a preterm infant indicate a need for tailored support. However, it is unclear which interventions work best. This review presents the evidence on existing healthcare interventions to support fathers of preterm infants in early parenthood, how effective they are and paternal experiences with the interventions. ELIGIBILITY CRITERIA: The integrative review process of Whittemore and Knafl was used to guide the study. A structured and comprehensive literature search was conducted in PubMed (MEDLINE), Embase, CINAHL, PsycInfo, Cochrane, Scopus, Web of Science, SweMed+, and Proquest Dissertation & Thesis Global. SAMPLE: A total of 18 qualitative and quantitative studies were included in the review. The Mixed Methods Appraisal Tool was used to assess quality. RESULTS: Three overall themes were identified in the analysis: 1) Skin-to-skin contact supported interaction between infant and father, 2) information impacted paternal experiences of stress, anxiety, and development of fatherhood, 3) fathers' relationships with the nurses oscillated between conflict and assistance. CONCLUSIONS: Our findings show that targeted interventions could support father-infant interaction and reduce stress among fathers of preterm infants. IMPLICATIONS: Fathers of preterm infants rely on nurses to support their engagement in early parenthood, while nurses facilitate the interventions that engage the fathers. It is also essential to develop a culture within the neonatal intensive care unit that encourages the presence of fathers and enhances educational nursing strategies for supporting fathers of preterm infants during early parenthood.

Compliance with the "Baby-friendly Hospital Initiative for Neonatal Wards" in 36 countries.

In 2012, the Baby-friendly Hospital Initiative for Neonatal Wards (Neo-BFHI) began providing recommendations to improve breastfeeding support for preterm and ill infants. This cross-sectional survey aimed to measure compliance on a global level with the Neo-BFHI's expanded Ten Steps to successful breastfeeding and three Guiding Principles in neonatal wards. In 2017, the Neo-BFHI Self-Assessment questionnaire was used in 15 languages to collect data from neonatal wards of all levels of care. Answers were summarized into compliance scores ranging from 0 to 100 at the ward, country, and international levels. A total of 917 neonatal wards from 36 low-, middle-, and high-income countries from all continents participated. The median international overall score was 77, and median country overall scores ranged from 52 to 91. Guiding Principle 1 (respect for mothers), Step 5 (breastfeeding initiation and support), and Step 6 (human milk use) had the highest scores, 100, 88, and 88, respectively. Step 3 (antenatal information) and Step 7 (rooming-in) had the lowest scores, 63 and 67, respectively. High-income countries had significantly higher scores for Guiding Principles 2 (family-centered care), Step 4 (skin-to-skin contact), and Step 5. Neonatal wards in hospitals ever-designated Baby-friendly had significantly higher scores than those never designated. Sixty percent of managers stated they would like to obtain Neo-BFHI designation. Currently, Neo-BFHI recommendations are partly implemented in many countries. The high number of participating wards indicates international readiness to expand Baby-friendly standards to neonatal settings. Hospitals and governments should increase their efforts to better support breastfeeding in neonatal wards.

'Now she has become my daughter': parents' early experiences of skin-to-skin contact with extremely preterm infants.

BACKGROUND: Based on the Family-Centred Care philosophy, skin-to-skin contact is a key activity in neonatal care, and use of this practice is increasing also with extremely preterm infants. Little is known about parents' immediate experiences of and readiness for skin-to-skin contact, while their fragile infant may still not be 'on safe ground'. Knowledge about parents' experiences might reduce doubt and reluctance among healthcare professionals to use skin-to-skin contact with extremely preterm infants and thus increase its dissemination in practice. AIMS AND OBJECTIVES: To explore parents' immediate experiences of skin-to-skin contact with extremely preterm infants <28-week postmenstrual age. METHODOLOGICAL DESIGN: A qualitative study using thematic analysis. RESEARCH METHODS: Thirteen semi-structured interviews conducted in 2008 with 16 parents after skin-to-skin contact with their extremely preterm infants analysed using inductive thematic analysis. FINDINGS: Parents' experiences were related to the process before, during and after skin-to-skin contact and moved from ambivalence to appreciating skin-to-skin contact as beneficial for both parents and infant. The process comprised three stages: (i) overcoming ambivalence through professional support and personal experience; (ii) proximity creating parental feelings and an inner need to provide care; (iii) feeling useful as a parent and realising the importance of skin-to-skin contact. Having repeatedly gone through stages 2 and 3, parents developed an overall confidence in the value of bonding, independent of the infant's survival. CONCLUSIONS: Parents progressed from ambivalence to a feeling of fundamental mutual needs for skin-to-skin contact. Parents found the bonding facilitated by skin-to-skin contact to be valuable, regardless of the infant's survival.

Why do mothers use nipple shields and how does this influence duration of exclusive breastfeeding?

The present study addressed the contentious discussions about the benefits and risks of nipple shield use. The objective was to explore self-reported reasons for using a nipple shield and examine associations pertaining to the mother, the infant and duration of breastfeeding. Data were collected from 4815 Danish mothers (68%) who filled out a self-administered questionnaire with open and closed question. Data were analyzed by content and statistical descriptive and multivariable analysis. Results showed that 22% of the mothers used nipple shields in the beginning and 7% used it the entire breastfeeding period. Primiparae used nipple shields more often than multiparae, and early breastfeeding problems as well as background factors like lower age, education and higher body mass index were associated with a higher likelihood of using nipple shields. Characteristics of infants associated with introducing nipple shields were lower- gestational age and birthweight. The use of nipple shields was furthermore found to be associated with a threefold increased risk of earlier cessation of exclusive breastfeeding: among primiparae odds ratio = 3.80 (confidence interval 2.61-5.53); among multiparae odds ratio = 3.33 (confidence interval 1.88-5.93). Mothers' own descriptions underlined how various early breastfeeding problems led to the use of nipple shields. Some mothers were helped through a difficult period; others described the use creating a kind of dependence. The results highlight how nipple shields may help breastfeeding mothers in the early period but is not necessarily a supportive solution to the inexperienced mother who needs extra support in the early process of learning to breastfeed.

Skin-to-skin care in neonatal intensive care units in the Nordic countries: a survey of attitudes and practices.

AIM: To investigate the application of skin-to-skin care (SSC) in the Nordic countries, the existence of guidelines for SSC and the attitudes of neonatal staff towards SSC. METHODS: One questionnaire was distributed at unit level and one at staff level in all Nordic neonatal intensive care units (n = 109). RESULTS: The unit questionnaire was answered by 95 (87%) units and the staff questionnaire by 1446 staff members (72%). All units offered SSC to various degrees, but guidelines only existed at 47% of them. Units in Denmark, Norway and Sweden seemed to use SSC earlier, longer and in more medically complicated situations than units in Finland and Iceland. Seventy-seven per cent of the units had private rooms where parents and infants could stay together, still the physical environment of the units limited the use of SSC. Medical risks were considered the main barrier for further implementation of SSC, while general development and early interaction were the most frequently mentioned benefits. CONCLUSION: Skin-to-skin care is implemented in all Nordic neonatal units, but offered to various degrees, to various populations and to varying extents. Danish, Norwegian and Swedish units are offering SSC more extensively than units in Finland and Iceland.

Breastfeeding practices in neonatal wards in Spain. Neo-BFHI international survey.

INTRODUCTION: In 2017, a worldwide survey was conducted on compliance with the practices promoted by Neo-BFHI (Baby-friendly Hospital Initiative expansion to neonatal wards). OBJECTIVE: To present the results of the Spanish wards that participated in the global survey and compare them with those obtained internationally. MATERIAL AND METHODS: Cross-sectional study through a survey on compliance with the Neo-BFHI ("Three basic principles", "Ten steps adapted to neonatal wards" and "the compliance with the International Code of Marketing of Breast-milk Substitutes" and subsequent relevant World Health Assembly resolutions). Compliance was calculated as the mean in each indicator and a final mean score for each neonatal unit. For the partial and final scores for each country and at the international level, the median was used. All scores ranged between 0 and 100. RESULTS: The response rate in Spain was 90%. The range of the national mean for neonatal wards were from 37 to 99, with no differences in the final score according to the level of care. The global score for Spain (72) is below the international median (77) and this also occurs in 8 of 14 items. The neonatal wards from BFHI designated hospitals, obtained a significantly higher mean global score, and in 9 of 14 items than the non-accredited ones. CONCLUSIONS: Both international and national results indicate an improvement in breast feeding practices in neonatal units. The benefits of the BFHI accreditation of maternity reach neonatal wards. Spain has several key points below the international score.

Compliance With the "Baby-Friendly Hospital Initiative for Neonatal Wards" in Russian Hospitals.

BACKGROUND: The expansion of the Baby-Friendly Hospital Initiative to neonatal wards, known as the Neo-BFHI, provides recommendations to support breastfeeding, as outlined in the Three Guiding Principles, the expanded Ten Steps, and the International Code for Marketing of Breast-Milk Substitutes. In 2017, Russia participated in an international survey about compliance with the Neo-BFHI. RESEARCH AIM: To assess breastfeeding support policies and practices in Russian neonatal wards at the country and federal district level in accordance with the Neo-BFHI recommendations. METHODS: This study was a prospective cross-sectional survey. We used the Neo-BFHI Self-Assessment questionnaire to collect data from neonatal wards that had all levels of care. A total of N = 60 Russian neonatal wards in hospitals that have ever been designated Baby-Friendly or planned to do so participated in the survey. RESULTS: Compliance scores at the federal district and country level ranging from 0-100 were used to summarize results. The median country overall score was 90 (IQR = 83 - 93). Respect for mothers, continuity of care, having a breastfeeding policy, and rooming-in had the highest median scores. Family-centered care, antenatal informing, skin-to-skin contact, and human milk use had the lowest median scores. Neonatal wards in the hospitals that were ever designated as Baby-Friendly had significantly higher scores than those that were never designated. Most respondents (n = 48, 80%) expressed a desire to obtain Neo-BFHI designation in their neonatal wards. CONCLUSION: Neo-BFHI recommendations can be successfully implemented in Russian neonatal wards at hospitals designated Baby-Friendly or planning to be designated.

Improved exclusive breastfeeding rates in preterm infants after a neonatal nurse training program focusing on six breastfeeding-supportive clinical practices.

BACKGROUND: Early breast milk expression, prolonged skin-to-skin contact, rooming-in, use of test-weighing and minimizing use of pacifiers are positively associated with exclusive breastfeeding of preterm infants, whereas use of nipple shields is negatively associated. AIM: To test whether a training program for neonatal nurses with a focus on these six breastfeeding-supportive clinical practices affects the rate of preterm infants exclusively breastfed at discharge to home, the postmenstrual age at establishment of exclusive breastfeeding, and maternal self-reported use of the practice in the neonatal intensive care unit, the. METHODS: A quasi-experimental multi-centre intervention study from 2016-2019 including a control group of 420 preterm mother-infant dyads, an intervention with a training program for neonatal nurses and implementation of weekly breastfeeding meetings for neonatal nurses, and an intervention group of 494 preterm mother-infant dyads. RESULTS: Significantly more preterm infants in the intervention group were exclusively breastfed at discharge to home (66.6%) than in the control group (58.1%) p = 0.008. There was no significant difference in postmenstrual age at establishment of exclusive breastfeeding between control and intervention group (37.5 vs.37.8 weeks, p = 0.073). Compared to the control group the number of infants continuing daily skin-to-skin contact after incubator care increased (83.2% vs. 88.3%, p = 0.035), infants using a nipple shield decreased (61.8% vs. 54.2%, p = 0.029), and the number of mothers initiating breast milk expression before six hours post-partum increased (32.6% vs. 42.4%, p = 0.007). There was a significant correlation between percentage of neonatal nurses participating in the breastfeeding training program and changes in exclusive breastfeeding rates (Pearson Correlation 0.638, p = 0.047). CONCLUSION: Exclusive breastfeeding rates in preterm infants and maternal self-reported use of breastfeeding-supportive practices increased by training neonatal nurses in the six clinical practices. It is important to include all nurses in the breastfeeding training program to ensure positive effect on exclusive breastfeeding rates.

Extremely preterm infants tolerate skin-to-skin contact during the first weeks of life.

AIM: To determine if clinically stable extremely preterm infants can maintain their temperature during skin-to-skin contact and to screen for other negative effects. METHODS: Continuous measurement of 22 stable infants' physical parameters 2 h before, during, and 2 h after skin-to-skin-contact. Mean gestational age at birth was 25 weeks and 4 days, mean post-natal age was 8 days, postmenstrual age was 26 weeks and 6 days, and mean actual weight 702 g. Mean duration of skin-to-skin-contact was 98 min. 16 infants were skin-to-skin with the mother, five with the father and one with an older sister. RESULTS: There were no significant differences in mean skin temperature, heart rate, respiration rate, or oxygen saturation before, during, and after skin-to-skin contact. While staying within normal range, the mean skin temperature increased 0.1 degrees C during skin-to-skin contact with the mother and decreased 0.3 degrees C during skin-to-skin contact with the father (p = 0.011) (without post-hoc correction). CONCLUSION: Clinically stable, extremely preterm infants can keep adequate skin temperature and adequate physical stability during skin-to-skin contact with their parents.

Nipple shield use in preterm infants: Prevalence, motives for use and association with exclusive breastfeeding-Results from a national cohort study.

BACKGROUND AND AIM: Prevalence and motives for nipple shield use are not well studied in preterm infants and recommendations of nipple shield use in preterm infants are inconsistent. The aim of this study was to determine the prevalence of nipple shield use, explore the motives for nipple shield use and elucidate the association with exclusive breastfeeding in preterm infants. METHODS: The study was part of a prospective survey of a Danish national cohort of preterm infants based on questionnaires answered by the 1221 mothers of 1488 preterm infants with gestational age of 24-36 weeks. Data on nipple shield use was available for 1407 infants. RESULTS: Nipple shields were used by 54% of the mother-infant dyads for many different motives and was more often related to breastfeeding problems associated with the infant than with the mother. The most common motive for nipple shield use was "infant slipped the nipple" (52%). The lower the gestational age, the more frequently nipple shields were used for motives related to the infant. For those using a nipple shield, only the motive "infant fell asleep at the breast" was associated with a higher risk of not breastfeeding exclusively at discharge (OR 1.90 (95% CI 1.15; 3.13), p = 0.012), and "breast too engorged" with a lower risk of not breastfeeding exclusively (OR 0.32 (0.16; 0.63), p = 0.001), but overall nipple shield use was associated with failure of exclusive breastfeeding. CONCLUSION: The present study does not give justifiable motives for nipple shield use, except for "breast too engorged". Nipple shields should not be recommended for infants falling asleep at the breast, instead, staff and mothers should be patient, allowing the dyad time skin-to-skin. The results indicate that the use of a nipple shield does not promote exclusive breastfeeding in preterm infants.

Growth and breastfeeding of preterm infants receiving neonatal tele-homecare compared to hospital-based care.

OBJECTIVE: Neonatal tele-homecare implies that parents of clinically stable preterm infants can manage tube feeding and establishment of oral feeding in the home. Support is provided from the neonatal intensive care unit (NICU) through a telehealth service. The aim of this study was to compare growth and breastfeeding rates amongst infants being managed in the NICU (conventional care) and by neonatal tele-homecare. METHODS: A total of 96 preterm infants with tube feeding requirements participated in the observational study of neonatal tele-homecare. Retrospective data in 278 preterm infants receiving standard care in the same neonatal intensive care unit prior to implementation of neonatal tele-homecare were used for comparison. Rates of breastfeeding and growth were monitored during neonatal tele-homecare. Infant weights were converted to standard deviation weight-for-age z-scores based on a reference. RESULTS: There was no significant difference in rates of exclusive breastfeeding between the neonatal tele-homecare infants and the controls. Among the very preterm singleton infants more neonatal tele-homecare infants were exclusively breastfed at discharge compared to the controls (p = 0.04). There was no significant difference in median weight for age z-scores at discharge. CONCLUSION: This study demonstrates that neonatal tele-homecare may be an appropriate model of care for the management of preterm infants outside of the hospital environment; with the added benefit of higher rates of breastfeeding at time of discharge for very preterm infants.

Eight principles for patient-centred and family-centred care for newborns in the neonatal intensive care unit.

Despite the recent improvements in perinatal medical care leading to an increase in survival rates, adverse neurodevelopmental outcomes occur more frequently in preterm and/or high-risk infants. Medical risk factors for neurodevelopmental delays like male gender or intrauterine growth restriction and family sociocultural characteristics have been identified. Significant data have provided evidence of the detrimental impact of overhelming environmental sensory inputs, such as pain and stress, on the developing human brain and strategies aimed at preventing this impact. These strategies, such as free parental access or sleep protection, could be considered 'principles of care'. Implementation of these principles do not require additional research due to the body of evidence. We review the scientific evidence for these principles here.

Breastfeeding progression in preterm infants is influenced by factors in infants, mothers and clinical practice: the results of a national cohort study with high breastfeeding initiation rates.

BACKGROUND AND AIM: Many preterm infants are not capable of exclusive breastfeeding from birth. To guide mothers in breastfeeding, it is important to know when preterm infants can initiate breastfeeding and progress. The aim was to analyse postmenstrual age (PMA) at breastfeeding milestones in different preterm gestational age (GA) groups, to describe rates of breastfeeding duration at pre-defined times, as well as analyse factors associated with PMA at the establishment of exclusive breastfeeding. METHODS: The study was part of a prospective survey of a national Danish cohort of preterm infants based on questionnaires and structured telephone interviews, including 1,221 mothers and their 1,488 preterm infants with GA of 24-36 weeks. RESULTS: Of the preterm infants, 99% initiated breastfeeding and 68% were discharged exclusively breastfed. Breastfeeding milestones were generally reached at different PMAs for different GA groups, but preterm infants were able to initiate breastfeeding at early times, with some delay in infants less than GA 32 weeks. Very preterm infants had lowest mean PMA (35.5 weeks) at first complete breastfeed, and moderate preterm infants had lowest mean PMA at the establishment of exclusive breastfeeding (36.4 weeks). Admitting mothers to the NICU together with the infant and minimising the use of a pacifier during breastfeeding transition were associated with 1.6 (95% CI 0.4-2.8) and 1.2 days (95% CI 0.1-2.3) earlier establishment of exclusive breastfeeding respectively. Infants that were small for gestational age were associated with 5.6 days (95% CI 4.1-7.0) later establishment of exclusive breastfeeding. CONCLUSION: Breastfeeding competence is not developed at a fixed PMA, but is influenced by multiple factors in infants, mothers and clinical practice. Admitting mothers together with their infants to the NICU and minimising the use of pacifiers may contribute to earlier establishment of exclusive breastfeeding.
