From tube to breast: the bridging role of semi-demand breastfeeding

Development of a Protocol for the Direct Breastfeeding of Premature Infants in Neonatal Intensive Care Units

PURPOSE

This study aimed to develop a direct breastfeeding protocol for premature infants admitted to neonatal intensive care units (NICUs) and investigate its efficacy.

BACKGROUND

Direct breastfeeding increases the amount and duration of breastfeeding. However, NICUs have low direct feeding rates owing to medical staff anxiety, lack of knowledge and experience, and fear of overwork. Accordingly, this study developed a protocol for direct breastfeeding in the NICU and evaluated its effect.

METHODS

The protocol was developed through a literature review, expert validation, and preliminary investigation. Its application effects were identified using a nonexperimental, evidence-based research design targeting premature infants, their mothers, and NICU nurses.

RESULTS

The protocol comprised 5 areas and 23 items. Application of the protocol resulted in continuous weight gain of the infants and increased self-efficacy in the mothers' direct breastfeeding ( t = 3.219, P = .004). Significant increases were noted in NICU nurses' direct breastfeeding activities ( t = 3.93, P < .001), breastfeeding rates in the NICU ( P = .037), and direct breastfeeding rates ( P = .007).

CONCLUSIONS

Results underscore the value of an evidence-based protocol for improving breastfeeding rates in premature infants. This study highlights the need for continuous nursing education on protocol applications and human resource support.

Cue-based versus scheduled feeding for preterm infants transitioning from tube to oral feeding: the Cubs mixed-methods feasibility study

BACKGROUND

There is a lack of evidence of the effect of cue-based feeding compared with scheduled feeding on important outcomes for preterm infants.

OBJECTIVES

The objectives were as follows: (1) to describe the characteristics, components, theoretical basis and outcomes of approaches to feeding preterm infants transitioning from tube to oral feeding; (2) to identify operational policies, barriers and facilitators, and staff and parents' educational needs in neonatal units implementing cue-based feeding; (3) to co-produce an intervention for feeding preterm infants in response to feeding cues; (4) to appraise the willingness of parents and staff to implement and sustain the intervention; (5) to assess associated costs of implementing cue-based feeding; (6) to determine the feasibility and acceptability of a future trial; (7) to scope existing data-recording systems and potential outcome measures; and (8) to determine stakeholders' views of whether or not a randomised controlled trial of this approach is feasible.

DESIGN

This was a mixed-methods intervention development and feasibility study comprising (1) a systematic review, case studies, qualitative research and stakeholder consensus; (2) the co-production of the intervention; (3) a mixed-methods feasibility study; and (4) an assessment of stakeholder preferences for a future evaluation.

SETTING

Three neonatal units in the UK (two level 3 units and one level 2 unit).

PARTICIPANTS

Developmentally normal, clinically stable preterm infants receiving enteral feeds (n = 50), parents (n = 15 pre intervention development; n = 14 in the feasibility study) and health-care practitioners (n = 54 pre intervention development; n = 16 in the feasibility study).

INTERVENTION

An evidence-informed multicomponent intervention comprising training, a feeding protocol, feeding assessment tools, supplementary training materials [including posters, a film and a narrated PowerPoint (Microsoft Corporation, Redmond, WA, USA) presentation] and the 'Our Feeding Journey' document.

MAIN OUTCOME MEASURES

The main outcome measures were recruitment and screening rates, infant weight gain, duration of the intervention, feeding outcomes, implementation outcomes (contextual facilitators and barriers, acceptability, adoption, appropriateness and fidelity) and stakeholder preferences for a future evaluation.

RESULTS

The systematic review of 25 studies concluded that evidence in favour of cue-based feeding should be treated cautiously. The case studies and qualitative research highlighted contextual barriers to and facilitators of the implementation of cue-based feeding. The telephone survey found that many neonatal units are considering implementing cue-based feeding. We recruited 37% of eligible infants, and there was good retention in the study until discharge but a high loss to follow-up at 2 weeks post discharge. The mean number of days from intervention to transition to full oral feeding was 10.8, and the mean daily change in weight gain was 25 g. The intervention was acceptable to parents and staff, although there was dissatisfaction with the study documentation. Intervention training did not reach all staff. A cluster-randomised design with a composite outcome was suggested by stakeholders for a future study.

LIMITATIONS

The intervention was available only in English. Intervention training did not reach all staff. There was low recruitment to qualitative interviews and observations. Only a small number of medical staff engaged in either the training or the interviews.

CONCLUSIONS

It is feasible to implement a cue-based feeding intervention with improved training and documentation. Further work is needed to assess the feasibility of a future trial, noting evidence of existing lack of equipoise.

FUTURE WORK

The next steps are to digitalise the intervention and conduct a survey of all neonatal units in the UK.

Effect of SINC Feeding Protocol on Weight Gain, Transition to Oral Feeding, and the Length of Hospitalization in Preterm Infants: A Randomized Controlled Trial

BACKGROUND

The present study aims to test the effect of the Safe Individualized Nipple-Feeding Competence (SINC) protocol on the preterm infants' weight gain, transition to oral feeding, and duration of hospitalization.

METHODS

The procedure was designed as a single-blind, parallel-group randomized controlled trial. The trial was conducted in a neonatal intensive care unit (NICU) in Konya, Turkey. Data were collected from 80 preterm infants between February 2018 and March 2019. Infants (gestational weeks 28-33) were randomly assigned to the intervention (n = 39) and control groups (n = 41). The intervention group received the SINC feeding protocol, whereas the control group received the standard feeding. Data were collected using the Family Information Form, the Preterm Infant Follow-Up Form, and the SINC Protocol Evaluation Checklist. Infants were followed from hospitalization to discharge. The outcomes were weight gain, transition to oral feeding, and the length of hospitalization from birth to discharge. Pearson χ² test, Fisher exact test, independent t-test, Mann-Whitney U test, and general linear model test were used in analyzing the data.

RESULTS

The main effects of groups on weight measurements were found to be statistically significant (P < .001). There were no significant differences in terms of the transition from gavage to full oral feeding and the length of hospitalization (P > .05).

CONCLUSIONS

SINC protocol positively influences weight gain in preterm infants. It is important to evaluate different evidence-based feeding methods both as they apply to the NICU stay and how they may affect long-term outcomes of preterm infant.

Implementation of Pre-/Post-Weights to Enhance Direct Breastfeeding in the NICU

Introduction

Mother's own milk (MOM) is recommended as the optimal nutrition for preterm infants. Direct breastfeeding (DBF) is correlated with a longer duration of receiving MOM during hospitalization. Infants' transition to DBF may be enhanced when accurate pre-/post-weights are incorporated into nursing practice. An evidence-based practice change was introduced to promote use and increase consistency in methodology of pre-/post-weights after DBF in the neonatal intensive care unit (NICU), with the ultimate goal of increasing DBF at hospital discharge.

Methods

The practice change was introduced through an educational program, a video demonstrating pre-/post-DBF weighing techniques, and a return-demonstration. A 10-item pre-/posttest was used to evaluate nurses' knowledge gained by an educational intervention that included seven knowledge questions, three attitude questions, and three demographic descriptors.

Results

Nurses' knowledge gained following the educational intervention was statistically significant (p < .001) using a paired t-test.

Conclusions

The use of pre-/post-DBF weights as an accurate assessment of MOM transfer can promote DBF during hospitalization through education of NICU nurses. Understanding nursing characteristics and attitudes can aid in promotion of DBF in the NICU by bedside nurses.

CARE GIVEN TO NEWBORNS FED BY GASTRIC TUBE: CONCEPTS AND PRACTICES

ABSTRACT Objective: to describe the conduct related to feeding care through gastric tube in neonates hospitalized in the Neonatal Intensive Care Unit, from scientific articles published in the last five years. Method: an integrative literature review was developed in the databases: MEDLINE, LILACS, SciELO, CINAHL and BDENF. The search for the studies was carried out in August 2016, in English, Spanish and Portuguese. Results: 33 articles were analyzed. The level of evidence was classified as level IV (30%), level VI (27%), level II (15%), level III (18%), level I, V and VII with 3% each. The analytical categories were: Gastric tubes, their materials and their use in the Neonatal Intensive Care Unit, Nursing care for enteral nutrition through gastric tube in the Neonatal Intensive Care Unit, From the tube the oral route. The time to reach total enteral nutrition is lower, as is the decrease in length of hospital stay. The largest losses of milk fat are during gastroclysis at the expense of gavage. The relationship of food tolerance to dietary dosage form and volumes is not yet conclusive. Nursing stands out: in favor of the bond with the family, in the physical examination and evaluation, in the positioning, in the non-nutritive suction during the diet, in the oral stimulus, in the observation and conduct regarding the gastric residue. Conclusion: due to the heterogeneity of the data, more randomized and qualitative clinical trials are required to better support the conduct and improvement of nursing care.

Responsive versus scheduled feeding for preterm infants

BACKGROUND

Feeding preterm infants in response to their hunger and satiation cues (responsive, cue-based, or infant-led feeding) rather than at scheduled intervals might enhance infants' and parents' experience and satisfaction, help in the establishment of independent oral feeding, increase nutrient intake and growth rates, and allow earlier hospital discharge.

OBJECTIVES

To assess the effect of a policy of feeding preterm infants on a responsive basis versus feeding prescribed volumes at scheduled intervals on growth rates, levels of parent satisfaction, and time to hospital discharge.

SEARCH METHODS

We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 1), MEDLINE via PubMed (1966 to 17 February 2016), Embase (1980 to 17 February 2016), and CINAHL (1982 to 17 February 2016). We also searched clinical trials' databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

Randomised controlled trials (RCTs) or quasi-RCTs that compared a policy of feeding preterm infants on a responsive basis versus feeding at scheduled intervals.

DATA COLLECTION AND ANALYSIS

Two review authors assessed trial eligibility and risk of bias and undertook data extraction independently. We analysed the treatment effects in the individual trials and reported the risk ratio and risk difference for dichotomous data and mean difference (MD) for continuous data, with respective 95% confidence intervals (CIs). We used a fixed-effect model in meta-analyses and explored the potential causes of heterogeneity in sensitivity analyses. We assessed the quality of evidence at the outcome level using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

MAIN RESULTS

We found nine eligible RCTs including 593 infants in total. These trials compared responsive with scheduled interval regimens in preterm infants in the transition phase from intragastric tube to oral feeding. The trials were generally small and contained various methodological weaknesses including lack of blinding and incomplete assessment of all randomised participants. Meta-analyses, although limited by data quality and availability, suggest that responsive feeding results in slightly slower rates of weight gain (MD -1.36, 95% CI -2.44 to -0.29 g/kg/day), and provide some evidence that responsive feeding reduces the time taken for infants to transition from enteral tube to oral feeding (MD -5.53, 95% CI -6.80 to -4.25 days). GRADE assessments indicated low quality of evidence. The importance of this finding is uncertain as the trials did not find a strong or consistent effect on the duration of hospitalisation. None of the included trials reported any parent, caregiver, or staff views.

AUTHORS' CONCLUSIONS

Overall, the data do not provide strong or consistent evidence that responsive feeding affects important outcomes for preterm infants or their families. Some (low quality) evidence exists that preterm infants fed in response to feeding and satiation cues achieve full oral feeding earlier than infants fed prescribed volumes at scheduled intervals. This finding should be interpreted cautiously because of methodological weaknesses in the included trials. A large RCT would be needed to confirm this finding and to determine if responsive feeding of preterm infants affects other important outcomes.

Duration of breastfeeding in preterm infants followed at a secondary referral service

Objective:

Identify and analyze variables associated with shorter duration of breastfeeding in preterm infants.

Methods:

Retrospective cohort of premature infants followed up at secondary referral service in the period of 2010-2015. Inclusion: first appointment in the first month of corrected age and have undergone three or more consultations. Exclusion: diseases that impaired oral feeding. Outcome: duration of breastfeeding. A total of 103 preterm infants were evaluated, accounting for 28.8% of the preterm infants born in the municipality in that period, with a power of study of 80%. Descriptive analysis, t-test, chi-square test, Kaplan-Meier curves and Cox regression were used. p-values <0.05 were considered significant.

Results:

The median duration of breastfeeding among preterm infants was 5.0 months. The risk of breastfeeding discontinuation among preterm infants with gestational age <32 weeks was 2.6-fold higher than for those born at 32 weeks or more and the risk of breastfeeding interruption in preterm infants who were receiving breastfeeding supplementation in the first outpatient visit was 3-fold higher when compared to those who were exclusively breastfed in the first consultation.

Conclusions:

The median duration of breastfeeding in preterm infants was below the recommended one and discontinuation was associated with gestational <32 weeks and the fact that the infant was no longer receiving exclusive breastfeeding in the first outpatient visit. When these two variables were associated, their negative effect on the median duration of breastfeeding was potentiated.

When is it safe to initiate breastfeeding for preterm infants?

BACKGROUND

Breast milk is the gold standard of nutrition for preterm infants. Yet, initiation of direct breastfeeding before 32 weeks' postconceptional age (PCA) is not common practice in many neonatal intensive care units (NICUs). Our clinical question was, "In preterm infants, when is it safe to initiate breastfeeding in infants <32 weeks PCA receiving enteral feedings?"

SEARCH STRATEGY

A review of the literature was compiled between February 2013 and January 2015 by using the following databases: CINAHL, Cochrane Systematic Review, Scopus, and PubMed. Articles found were written in English and published after 1985. Key words were utilized during searches and references were hand checked.

RESULTS

Our review revealed that stable preterm infants maintain their physiological status during exposure to the breast as early as 27 to 28 weeks' PCA. Several studies demonstrated infants during breastfeeding compared with bottle-feeding experienced minimal variation in oxygen saturation and heart rate during feeding. Some infants exposed to the breast before 30 weeks' PCA were exclusively breastfeeding (direct breastfeeding and breast milk) at 32.8 weeks' PCA. Skin-to-skin mother-infant contact is crucial to the successful transition to direct breastfeeding.

IMPLICATIONS FOR PRACTICE AND RESEARCH

The transition from enteral feedings to direct, exclusive breastfeeding should involve frequent mother-infant skin-to-skin contact requiring support and guidance from the NICU staff. Future research should involve creating standard protocols within NICUs to facilitate breastfeeding transition and exploring barriers that may prevent the preterm infant from achieving direct, exclusive breastfeeding.
