Cue-based feeding in the NICU: using the infant's communication as a guide

Systemizing and Transforming Preterm Oral Feeding Through Innovative Algorithms

Background: Establishing safe and efficient oral feeds for preterm infants is one of the last milestones to be achieved prior to discharge home. However, this process commonly elicits stress and anxiety in both care providers, such as nurses and the entire healthcare team in the Neonatal Intensive Care Unit (NICU), as well as parents. These feelings of uncertainty are exacerbated by the non-linear progression of oral feeding development and the absence of a systematized approach to initiate and advance feedings. Methods: In this 48-bed tertiary perinatal centre, staff surveys and a needs assessment showed dissatisfaction and increasing stress and anxiety due to the inconsistencies in initiating and advancing oral feeds. This paper describes the formation of a multidisciplinary feeding committee which reviewed various oral feeding training materials and the ultimate creation of two innovative oral feeding algorithms and their corresponding education materials. Results: The Sunnybrook Feeding Committee has developed two evidence-based algorithms, one for initiating oral feeds and another for monitoring progress with objective decision-making points during common oral feeding challenges. To complement and support these algorithms, educational materials and a comprehensive documentation process were also created. These resources included detailed instructions, visual aids, and step-by-step guides to help staff understand and apply the algorithms effectively. Additionally, the educational materials aimed to standardize training and ensure consistency across the NICU, further promoting a systematic approach to preterm oral feeding. Implementation of these algorithms also aimed to provide evidence-based, expert-guided guidelines for assessing readiness, initiating feeds, monitoring progress, and making necessary adjustments. Conclusions: This structured approach lays the foundation for a unit-wide language and systematic process for oral feeding. The next steps in this quality improvement project involve educating and piloting the implementation of the developed oral feeding algorithms, gathering staff feedback, and refining the tools accordingly. The goal is to enhance overall care quality, reduce stress for both care providers and parents, and ensure the best possible start for vulnerable preterm infants, ultimately supporting a smooth and successful transition to home.

[Experiences of parents of premature infants in their feeding journey]

Premature birth is an ordeal for parents, and can have repercussions on the bond of attachment. The risk of stress can be reduced by involving parents in care and feeding, and by encouraging their presence with their baby. The aim of the study was to understand parents' experience of their premature baby's feeding times. Eleven families were included. Parents' experiences differed according to their ability to engage in feeding patterns, influenced by their baby's state of health and immaturity, and by the medical environment. Many expressed the need for support in coping with emotional and practical challenges.

Practices supporting cue-based breastfeeding of preterm infants in neonatal intensive care units across Europe

BACKGROUND

Emerging knowledge about supportive neurodevelopmental neonatal care shows the need for an individual approach to establish breastfeeding. However, evidence on how cue-based breastfeeding is supported in neonatal intensive care units (NICUs) is scarce. Therefore, the aim was to describe supporting practices for cue-based breastfeeding.

METHOD

Through Delphi rounds, a questionnaire was developed comprising questions on the usage and occurrence of supportive practices for cue-based breastfeeding. A multinational online survey was distributed September to October in 2023 to NICUs in Europe using snowball sampling. Practices such as the practice of skin-to-skin contact (SSC), restrictions for breastfeeding, providing information to parents, observing and responding to infants' cues were explored.

RESULTS

The survey was completed by 105 neonatal units across 15 European countries. Less than half (46%) of the NICUs had no restrictions upon placing the infant in SSC with the parents. Approximately half (49%) of the NICUs stated that infants had SSC within the first hour after birth. Many units (68%) had some restriction for breastfeeding. One week after birth, 48% of the NICUs encouraged breastfeeding for infants at 33 postmenstrual age whenever the infant showed cues, regardless of scheduled tube feeding time. This percentage increased to 59% at 33-35 gestational age. Less than half of the units (47%) stated that they had the necessary tools/instruments to support the transition from tube feeding to breastfeeding. There were variations in how milk intake was assessed, such as weighing before and after breastfeeding or estimating milk intake by time spent sucking. Infants in 50% of the units had to be fed exclusively orally before discharge. Many units (65%) provided specific support to or enabled discharge before the infant was exclusively orally fed.

CONCLUSION

European NICUs employ supportive practices, SSC, early initiation of breastfeeding, and provide information to parents. Staff plays a significant role in fostering cue-based feeding in preterm infant-mother dyads. There still exist restrictions for SSC and breastfeeding. To understand the impact of different strategies and practices, there is need for evaluations by parents and testing of the implementation of cue-based feeding practices in neonatal care.

Effectiveness of a Novel Feeding Algorithm for Oral Feeding Transition of Infants Born Prematurely

BACKGROUND

Feeding skill acquisition is commonly a limiting factor determining when an infant born prematurely can be discharged.

PURPOSE

This study aimed to determine if the addition of a novel feeding progression algorithm (combination of objective data from a suck measurement device and slow flow/low variability nipples) to current neonatal intensive care unit (NICU) standards could decrease feeding-related length of stay (primary outcome). We hypothesized that by timing the initiation of oral feedings to coincide with adequate sensory-motor skill development, feeding-related length of stay may be decreased.

METHODS

This was a prospective intervention study, with a historical control cohort, of infants born less than 30 weeks' gestational age without comorbidities affecting feeding skill acquisition at a Regional Level III-S NICU at a women and infant's hospital in Louisiana. A novel feeding progression algorithm utilized objective assessment of sucking to determine progression in nipple flow rates with slow flow/low variability nipples (flow rates from 0 to 9 mL/min) for infants receiving intervention (n = 18). Thirty-six controls who did not receive the feeding progression algorithm were identified via electronic medical record retrospective chart review.

RESULTS

Eighteen completed the study. Compared to the control group, infants receiving feeding interventions had delayed sequencing initiation, extended time between initially off positive pressure ventilation and initiation of sequencing, and decreased feeding-related length of stay, with similar total length of stay.

IMPLICATIONS FOR PRACTICE AND RESEARCH

This study adds to existing research supporting the effectiveness of novel feeding progression algorithms and interventions to support the health and outcomes of infants born prematurely. Future research should focus on implementation studies for feeding progression algorithm integration into standard NICU care.

The Effect of Breast Milk Odor on Feeding Cues, Transition Time to Oral Feeding, and Abdominal Perfusion in Premature Newborns: A Randomised Controlled Trial

PURPOSE

The present study was conducted to determine the effect of odor stimulation with breast milk (BM) applied to premature newborns before and during enteral feeding on feeding cues, transition time to oral feeding and abdominal perfusion.

DESIGN

This study was a parallel group pretest-post test randomised controlled trial (RCT).

METHODS

The study was conducted in the neonatal intensive care unit (NICU) in Türkiye. Study data were collected from 32 premature newborns between October 2020 and December 2021. Newborns were randomly assigned to either intervention (n = 16) or control (n = 16) groups. Odor stimulation with BM was applied to newborns in the intervention group (IG) before and during enteral feeding for 3 days. Data were collected with the Newborn Information Form, Abdominal Perfusion Follow-up Form, and Feeding Cues Follow-up Form. Yates corrected and Fisher chi-squared test, Mann-Whitney U test, Cohen Kappa statistics, Permanova analysis, and Wilcoxon test were used in the analysis. The study was registered in ClinicalTrials.gov (NCT04843293).

RESULTS

The frequency of feeding cues in newborns who were exposed to the odor of BM, was higher than in the control group (CG) (p < .05). The transition times to oral feeding were similar in newborns in the IG and CG (p > .05). Abdominal perfusion level of newborns in the IG was higher than the CG (p < .05), and the level of abdominal perfusion showed a significant difference in terms of group*time interaction (p < .05).

CONCLUSION

Our findings suggest that odor stimulation with BM will be beneficial in improving the digestive functions of premature newborns.

Preterm infant cues during breastfeeding and its measurement: A scoping review

Background

Preterm infants display certain behaviors to communicate their needs, known as preterm infant cues. However, the existing research on preterm infant cues primarily draws from studies conducted on bottle-fed infants rather than breastfed infants.

Objective

This study aimed to investigate the concept of preterm infant cues during breastfeeding and its appropriate instruments.

Design

A scoping review.

Data Sources

The articles published up to January 2022 were searched from multiple sources from EBSCOhost Web, namely CINAHL Plus with Full Text, MEDLINE, ERIC, and E-Journals.

Review Methods

The articles retrieved for this review were screened using PICO (Population, Intervention, Comparison, and Outcomes) format. Preferred Reporting Items for Systematic Reviews (PRISMA) checklist was used in selecting the articles, and Joanna Briggs Institute Critical Appraisal was utilized by two independent authors to assess the articles' quality. A descriptive method was used to analyze the data.

Results

The initial review stage found 183 potential articles, but only four satisfied the criteria. The notion of preterm infant cues during breastfeeding is centered on the actions of preterm infants while positioned on their mother's chest. These feeding cues are identifiable before, during, and after breastfeeding and include cues for hunger, self-regulation, stress, satiation, approach, avoidance, and sucking quality. To effectively recognize these cues, tools such as the Preterm Infants Cues Coding System (PFCCS), Infant Driven Scale (IDS), Newborn Individualized Developmental Care and Assessment Program (NIDCAP), and Preterm Breastfeeding Behavior Scale (PIBBS) can be utilized.

Conclusion

The study findings highlight the importance of recognizing preterm infant cues during breastfeeding to facilitate proper feeding and developmental care. Observational studies have proven to be an effective means of observing these cues during breastfeeding. By leveraging the cues identified in this review alongside tools such as PFCCS, IDS, NIDCAP, and PIBBS, nurses can accurately interpret preterm infants' breastfeeding cues in neonatal care settings of all levels. This, in turn, can aid in developing care plans that promote better feeding ability outcomes.

Effect of cue-based feeding on time to nipple feed and time to discharge in very low birth weight infants

The objective of this study is to evaluate the effectiveness of a cue-based feeding protocol in improving time to nipple feed and time to discharge in very low birth weight infants in a Level III Neonatal Intensive Care Unit. Demographic, feeding, and discharge data were recorded and compared between the two cohorts. The pre-protocol cohort included infants born from August 2013 through April 2016 and the post-protocol cohort included infants born from January 2017 through December 2019. 272 infants were included in the pre-protocol cohort and 314 infants in the post-protocol cohort. Both cohorts were statistically comparable in gestational age, gender, race, birthweight, prenatal care, antenatal steroid use, and rates of maternal diabetes. There were statistically significant differences between the pre- versus post-protocol cohorts in median post-menstrual age (PMA) in days at first nipple feed (PO) (240 vs 238, p = 0.025), PMA in days at full PO (250 vs 247, p = 0.015), and length of stay in days (55 vs 48, p = 0.0113). Comparing each year in the post-protocol cohort, for each outcome measure, a similar trend was noted in 2017 and 2018, but not in 2019. In conclusion, the cue-based feeding protocol was associated with a decrease in the time to first PO, time to full nipple feeds, and the length of stay in very-low-birthweight infants.

Core components of a rehabilitation program in pediatric cardiac disease

There is increasing effort in both the inpatient and outpatient setting to improve care, function, and quality of life for children with congenital heart disease, and to decrease complications. As the mortality rates of surgical procedures for congenital heart disease decrease, improvement in perioperative morbidity and quality of life have become key metrics of quality of care. Quality of life and function in patients with congenital heart disease can be affected by multiple factors: the underlying heart condition, cardiac surgery, complications, and medical treatment. Some of the functional areas affected are motor abilities, exercise capacity, feeding, speech, cognition, and psychosocial adjustment. Rehabilitation interventions aim to enhance and restore functional ability and quality of life for those with physical impairments or disabilities. Interventions such as exercise training have been extensively evaluated in adults with acquired heart disease, and rehabilitation interventions for pediatric patients with congenital heart disease have similar potential to improve perioperative morbidity and quality of life. However, literature regarding the pediatric population is limited. We have gathered a multidisciplinary team of experts from major institutions to create evidence- and practice-based guidelines for pediatric cardiac rehabilitation programs in both inpatient and outpatient settings. To improve the quality of life of pediatric patients with congenital heart disease, we propose the use of individualized multidisciplinary rehabilitation programs that include: medical management; neuropsychology; nursing care; rehabilitation equipment; physical, occupational, speech, and feeding therapies; and exercise training.

Effects of Infant Driven Feeding Program on Provision of Breast Milk in Very Low Birth Weight Infants

Background: The ability to complete nipple feedings is one of the discharge criteria for most premature neonates. The Infant Driven Feeding (IDF) program suggests a system of objective promotion of oral feeds in premature infants. There is a lack of studies systematically studying the effects of IDF on the provision of breast milk. Methods: This was a retrospective study of all premature infants born before 33 weeks and birth weight of <1,500 g admitted to a level IV neonatal intensive care unit. Infants on IDF were compared with those not on IDF. Results: A total of 46 infants in the IDF group and 52 in the non-IDF group met the inclusion criteria. A higher number of infants in the IDF group breastfed at first oral attempt (54% versus 12%). Forty-five percent of IDF mothers completed a full 72 hours of protected breastfeeding at the start of oral feeds, and IDF infants had earlier removal of nasogastric (NG) tube. There was no difference in the provision of breast milk and/or breastfeeding on discharge between the two groups. There was no difference in the length of stay between the two groups. Conclusion: The IDF program attempts to streamline the promotion of oral feeds in very low birth weight infants. Higher incidence of breastfeeding at the start of oral feeds and earlier removal of NG tube did not translate into higher provision of breast milk on discharge in very low birth weight infants in the IDF group. Prospective randomized trials are needed to validate cue-based infant driven feeding programs and their effects on the provision of breast milk.

Postnatal growth of small for gestational age late preterm infants: determinants of catch-up growth

BACKGROUND

Failure to recover growth is a risk reported in late preterm population. This study aimed to evaluate the auxological outcome of late preterm infants and identify factors associated with failure to recover growth.

METHODS

We enrolled late preterm infants with birth weight ≤10th percentile, followed up at High-Risk Infant Follow-up Service. We collected data at birth and at follow-up visits. A logistic regression analysis was performed to assess variables independently associated with growth failure.

RESULTS

The population consisted of 175 preterms. The percentage of children showing no weight recovery was 34% at 36 months. At logistic regression analysis, infants who had not regained weight at 12 months had a higher risk of not regaining weight even at 36 months. The same risk factor was highlighted for length catch-up growth. Moreover, infants fed any human milk at discharge were protected from not achieving both weight and length catch-up growth at 36 months.

CONCLUSION

These results indicate that children born late preterm and small for gestational age could fail to recover weight and stature growth in the first 36 months. The protective effect of human milk on failure to thrive highlights the importance of promoting breastfeeding in this population.

IMPACT

A significant number of SGA late preterms show a failure to recover weight and statural growth. Having experienced intrauterine growth restriction is associated with a greater chance of achieving statural catch-up growth. Being born singleton represents a risk factor for slower weight and height growth velocity. Breastmilk has a protective effect on failure to recover adequate weight and length in preterm SGA infants. This finding highlights the importance of promoting breastfeeding in this population.

Implementing an Evidence-Based Feeding Protocol: Impact on Nurses' Knowledge, Perceptions, and Feeding Culture in the NICU

BACKGROUND

Evidence-based feeding practices are often variable among neonatal providers due to lack of knowledge and neonatal intensive care unit (NICU) feeding culture norms.

PURPOSE

To evaluate changes in NICU nurses' knowledge, perceptions, feeding practices and culture following education about, and implementation of, an evidence-based Infant-Driven Feeding (IDF) protocol.

METHODS

A pre-/postprospective comparative design was used to survey 120 registered nurses employed in a level 3 NICU about feeding practices, knowledge, and culture prior to IDF education and 1 to 2 months after IDF implementation.

RESULTS

The preeducation survey yielded 59 respondents; of these, 30 responded to the same survey after IDF implementation. Postimplementation responses were significant for fewer nurses making decisions to begin oral feedings ( P = .035), greater use of gestational age to increase frequency of oral feeding attempts ( P = .03), less reliance on weight loss to decrease oral feeding attempts ( P = .018), an increase in use of combination interventions to prepare infants for oral feeding ( P = .001), and greater willingness to allow a rest period or stop the feeding if an infant falls asleep after completing 70% of the feeding ( P = .03).

IMPLICATIONS FOR PRACTICE AND RESEARCH

Trends in several survey categories following the education program and implementation of IDF support the use of evidence-based practices (EBPs) such as IDF. Future research focused on nurses' perceptions of how education influences integration of specific EBPs into practice is needed. Evaluating EBP mentorship combined with education about EBPs can provide insights on how best to integrate EBPs into practice.

Effects of Swaddling During Bottle Feeding in Preterm Infants

BACKGROUND

Preterm infants have immature oral feeding skills, affecting length of hospital stay and long-term feeding outcomes. Swaddling has positive effects on pain and stress responses, state regulation, and physiological stability in preterm infants in the neonatal intensive care unit (NICU). Swaddling during bottle feeding may support preterm infant behavioral organization and oral feeding skills. Swaddling is used inconsistently during feeding in the NICU and has not been critically examined for effects on bottle feeding performance in preterm infants.

PURPOSE

To examine the effects of swaddling on bottle feeding quality and efficiency in preterm infants.

METHODS

A convenience sample of 30 infants born before 34 weeks of gestation was selected in an urban level IV NICU. Using an experimental, randomized crossover design, each infant was swaddled for one feeding and unswaddled for one feeding. Feeding efficiency was measured by rate and volume consumed. Feeding quality was examined by the Early Feeding Skills Assessment and frequency of physiological changes. Data were analyzed using dependent t tests and Wilcoxon signed rank test.

RESULTS

When swaddled, participants demonstrated significantly better scores on all related subtests of the Early Feeding Skills Assessment ( P ≤ .001). Infants demonstrated no difference in frequency of bradycardia or oxygen desaturations greater than 4 seconds. No significant differences were found in feeding efficiency outcomes.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Swaddling can be used in the NICU to improve bottle feeding quality in preterm infants. Future investigation is needed on long-term effects of swaddling during bottle feeding on feeding performance, weight gain, and length of stay.

Responsive Feeding for Preterm or Low Birth Weight Infants: A Systematic Review and Meta-analysis

BACKGROUND AND OBJECTIVES

Responsive feeding may improve health outcomes in preterm and low birth weight (LBW) infants. Our objective was to assess effects of responsive compared with scheduled feeding in preterm and LBW infants.

METHODS

Data sources include PubMed, Scopus, Web of Science, CINAHL, LILACS, and MEDICUS. Randomized trials were screened. Primary outcomes were mortality, morbidity, growth, neurodevelopment. Secondary outcomes were feed intolerance and duration of hospitalization. Data were extracted and pooled with random-effects models.

RESULTS

Eleven eligible studies were identified, and data from 8 randomized control trials with 455 participants were pooled in the meta-analyses. At discharge, the mean difference in body weight between the intervention (responsive feeding) and comparison (scheduled feeding) was -2.80 g per day (95% CI -3.39 to -2.22, I2 = 0%, low certainty evidence, 4 trials, 213 participants); -0.99 g/kg per day (95% CI -2.45 to 0.46, I2 = 74%, very low certainty evidence, 5 trials, 372 participants); -22.21 g (95% CI -130.63 to 86.21, I2 = 41%, low certainty evidence, 3 trials, 183 participants). The mean difference in duration of hospitalization was -1.42 days (95% CI -5.43 to 2.59, I2 = 88%, very low certainty evidence, 5 trials, 342 participants). There were no trials assessing other growth outcomes (eg, length and head circumference) mortality, morbidity or neurodevelopment. Limitations include a high risk of bias, heterogeneity, and small sample size in included studies.

CONCLUSIONS

Overall, responsive feeding may decrease in-hospital weight gain. Although the evidence is very uncertain, responsive feeding may slightly decrease the duration of hospitalization. Evidence was insufficient to understand the effects of responsive compared with scheduled feeding on mortality, morbidity, linear growth, and neurodevelopmental outcomes in preterm and LBW infants.

A Literature Review of Feeding Disorders in Children with Tracheostomies and Ventilators

Feeding disorders and gastrostomy use are highly prevalent in children with invasive mechanical ventilation (IMV) due to both common risk factors (eg, prematurity, neurological disorders) and resultant experiential deprivation (eg, long hospitalizations, delayed feeding experiences). Feeding in children with IMV is complicated by the presence of a tracheostomy, lung vulnerability, and medical complexity. The potential comorbidity of swallowing difficulties (dysphagia) and atypical early feeding experiences can result in complex feeding disorders. In this review of pediatric feeding disorders in children with invasive mechanical ventilation (IMV), we identify gaps in clinical translational research for this patient population and opportunities for improving evidence-based management. To improve long-term feeding outcomes and maximize oral feeding in this vulnerable population, children would benefit from earlier feeding opportunities during critical developmental windows, standardized protocols for advancing oral feeding, and involvement of intensive, comprehensive therapies throughout hospitalizations and early childhood.

Feeding outcomes in post-discharge feeding clinic for infants following cardiac surgery

INTRODUCTION

The aim of this study was to describe the development and assess the usefulness of a feeding clinic to help infants with CHD tolerate the highest level of oral feeding while achieving growth velocity and supporting neurodevelopment.

MATERIALS AND METHODS

This retrospective, cohort study assessed feeding outcomes for infants who underwent cardiac surgery at <30 days of age with cardiopulmonary bypass between February 2016 and April 2020. Diagnoses, age at surgery, hospitalisation variables, and feeding outcomes were compared between two cohorts, pre- and post-implementation of a specialised feeding clinic using Exact Wilcoxon signed-rank test, chi-squared, or Fisher's exact test. The association between time to full oral feed and risk factors was assessed using univariable and multivariable Cox regression model.

RESULTS

Post-clinic infants (n = 116) surgery was performed at a median of 6 days of life (interquartile range: 4, 8) with median hospital length of stay of 19 days (interquartile range: 16, 26). Infants' median age at first clinic visit was at 30 days old (interquartile range: 24, 40) and took median 10 days (interquartile range: 7, 12) after hospital discharge to first clinic visit. In the post-clinic cohort, the median time to 100% oral feeding was 47 days (interquartile range: 27, 96) compared to the 60 days (interquartile range: 20, 84) in the pre-clinic cohort (n = 22), but the difference was not statistically significant.

DISCUSSION

The cardiac feeding clinic was utilised by our neonatal surgery population and feasible in coordination with cardiology follow-up visits. Future assessment of cardiac feeding clinic impact should include additional measures of feeding and neurodevelopmental success.

Increasing Student Confidence With Medically Complex Infants Through Simulation: A Mixed Methods Investigation

PURPOSE

The purpose of this study was to compare student knowledge and confidence, related to the assessment and management of oral feeding readiness in medically complex infants, following a written case study versus a high-fidelity human patient simulation (HPS).

METHOD

A sequential, two-phase, embedded mixed methods design was conducted. Participants were two sequential cohorts of second-year speech-language pathology graduate students enrolled in a didactic Pediatric Dysphagia course. At the end of the course, students completed the same case scenario presented as a written case study (control group; N = 28) or as an HPS (experimental group; N = 24). Pre- and post-knowledge assessment results and self-assessments of confidence conducted at three time points were compared.

RESULTS

All students made gains in knowledge, regardless of intervention (written case study or HPS). Despite different baselines, the percent change in knowledge was significant with the control group improving 33% and the experimental group improving 76% from baseline. Students in the experimental group demonstrated significantly greater gains in confidence with skills enhanced by the hands-on, immersive experience of HPS. Qualitative analysis further identified factors contributing to increased confidence with all students reporting that experience significantly contributes to their confidence in their ability to treat patients.

CONCLUSIONS

While knowledge outcomes were similar between the groups, the confidence that the experimental group gained through the hands-on experiences of HPS fosters student development as confident professionals in assessing feeding readiness and managing medically complex infants. Results support integration of simulation into the graduate curriculum to support student learning.

Cue-based feeding and short-term health outcomes of premature infants in newborn intensive care units: a non-randomized trial

BACKGROUND

Feedings based on behavioral cues is a method relying on infants' behavioral expressions of readiness to feed. The objective of this interventional study was to determine the effect of cue-based feeding on the short-term health outcomes of preterm infants.

METHODS

This quasi-experimental study utilized a historical or phase lag design. It involved 60 preterm infants admitted to an Iranian referral hospital's Level III-Newborn Intensive Care Unit (NICU) from April 2017 until January 2018. The experimental group (n = 30) received a three-step intervention of offering behavioral-cue-based oral (BCBO) feedings: Step 1 - One BCBO feeding every 12 hours for 3 days; Step 2 - Two BCBO feedings every 12 h for 3 days; and Step 3 - All feedings as BCBO feedings for 3 days. The control group received standard care feedings. Group difference data were analyzed with SPSS version 16 using descriptive and inferential statistics.

RESULTS

The infants' mean weight at time of discharge for the intervention and control groups were 1492.79 ± 21.65 g and 1395.71 ± 17.61 g (P = .003) respectively. The mean durations of achieving full oral feedings in the intervention and control groups were 17 ± 6 and 20 ± 11 days, respectively (P = .19). The mean frequencies of hypoxia were 1 ± 1.54 and 5 ± 9.31 respectively (P = .03) and of gavage feedings 725 ± 584 and 1846 ± 2097 respectively (P = .009). No apnea events were reported for the intervention group; the frequency of apnea in the control group was 1 ± 2.11 (P = .16).

CONCLUSION

The findings indicate that cue-based feeding is beneficial for preterm infants. Therefore, it is recommended that nurses employ cue-based feeding in the NICU.

Partial Enteral Discharge Programs for High-risk Infants

Premature infants or infants born with complex medical problems are at increased risk of having delayed or dysfunctional oral feeding ability. These patients typically require assisted enteral nutrition in the form of a nasogastric tube (NGT) during their NICU hospitalization. Historically, once these infants overcame their initial reason(s) for admission, they were discharged from the NICU only after achieving full oral feedings or placement of a gastrostomy tube. Recent programs show that these infants can be successfully discharged from the hospital with partial NGT or gastrostomy tube feedings with the assistance of targeted predischarge education and outpatient support. Caregiver opinions have also been reported as satisfactory or higher with this approach. In this review, we discuss the current literature and outcomes in infants who are discharged with an NGT and provide evidence for safe practices, both during the NICU hospitalization, as well as in the outpatient setting.

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.

Positive breastfeeding experiences and facilitators in mothers of preterm and low birthweight infants: a meta-ethnographic review

Background

Most qualitative research on breastfeeding the preterm or low-birthweight (LBW) infant has focused on negative insights; there are no comprehensive insights into how, when and why mothers experience positive breastfeeding experiences. We aimed to address this knowledge gap by exploring what characterizes and facilitates a positive breastfeeding experience in mothers of preterm and/or LBW infants.

Methods

A systematic review using meta-ethnographic methods was conducted. Search strategies involved a comprehensive search strategy on six bibliographic databases, citation tracking and reference checking. The analysis involved a reciprocal level of translation and a line of argument synthesis.

Results

Searches identified 1774 hits and 17 articles from 14 studies were included, representing the views of 697 mothers. A positive breastfeeding experience was identified as being ‘attuned’. Three themes and eight sub-themes were developed to describe what characterizes attuned breastfeeding. ‘Trusting the body and what it can do’, concerned how attuned breastfeeding was facilitated through understanding the bodily responses and capacity and feeling comfortable with holding the infant and to breastfeed. ‘Being emotionally present – in the here and now’ described the importance of feeling relaxed and reassured. ‘Experiencing mutual positive responses’, illuminated how attunement was related to feelings of mutuality - when the mother recognises the infant’s cues, responds to these signals and receives a positive response from the infant. The key factors to facilitate attuned breastfeeding were opportunities for prolonged close physical contact with the infant, positive relationships with and support from staff and peers, and being facilitated to breastfeed when the infant showed feeding cues.

Conclusions

This study provides new insights into what characterizes a positive breastfeeding experience and how staff can facilitate and enable mothers to achieve attuned breastfeeding. Improvements in units’ design, such as for rooming-in and having prolonged skin-to-skin contact, and care provided by knowledgeable, supportive and encouraging staff and peers, are crucial. The mother’s physical and emotional states and the infant’s behavioural responses and physiological signals should guide the process towards positive breastfeeding practices.

The Effect of Training on Neonatal Nurses' Knowledge about Transitioning Preterm Infants to Oral Feeding

BACKGROUND

Neonatal nurses require knowledge of evidence-based interventions that can be utilized for supporting oral feeding skills in preterm infants. Little is known about the impact of education/training programs on neonatal nurses' knowledge of this topic.

PURPOSE

This study was conducted to determine the effect of a training program about evidence-based interventions for the transition to and support of oral feeding in preterm infants on the knowledge levels of neonatal nurses.

METHODS

We conducted a pretest-posttest studywith 73 neonatal nurses in a research and training hospital. Participants completed a demographic information form and their knowledge about oral feeding in preterm infants was assessed before and after a 240-min training about the transition to oral feeding and evidence-based therapeutic interventions to promote preterm infants' oral feeding skills.

RESULTS

Posttest scores evaluated at 1 week (81.6 ± 6.8) and 1 month (79.5 ± 6.5) after the training were significantly higher than pre-test scores (66.8 ± 6.9) (p < 0.001).

CONCLUSION

Neonatal nurses showed higher levels of knowledge about evidence-based interventions for supporting oral feeding skills in preterm infants at 1 week and 1 month after the training program compared to their knowledge before training.

IMPLICATIONS FOR PRACTICE

Providing training to neonatal intensive care nurses on the transition to oral feeding in preterm infants will increase their level of knowledge and ensure that oral feeding interventions for preterm infants can be implemented using evidence-based therapeutic methods.

Influence of patterns of neonatal transfers on breastfeeding outcomes

AIM

To investigate/evaluate the impact of hospital transfers on breastfeeding outcomes for infants requiring neonatal intensive care and to explore approaches to supporting lactation and breastfeeding.

METHODS

A national study of two cohorts of infants admitted to the nine neonatal intensive care units (NICUs) in New South Wales (NSW) Australia using data sourced from a prospectively collected NICUS data collection.

RESULTS

A total of 7829 infants were admitted to the nine NICUs in NSW for two 18-month cohorts (2012/2013 and 2015/2016) and were included in the study. These infants experienced 17 238 transfers to 107 different hospitals during the study period. Multiple transfers and low gestational age were independently associated with lower breastfeeding rates at hospital discharge across both cohorts. Extremely preterm infants and those with the greatest number of hospital transfers are least likely to be breastfed at time of discharge. Breastfeeding rates remained unchanged over time. The level of lactation support varied across NICUs.

CONCLUSION

This study highlights the challenges of establishing and maintaining breastfeeding for infants requiring intensive care who have had multiple hospital transfers for continuing or specialist care. There is wide variation in lactation support across facilities. The importance of a consistent approach, education programmes and the provision of appropriate lactation support is emphasised.

The Social Organization of Neonatal Nurses' Feeding Work

PURPOSE

We report findings from an institutional ethnography (IE) of nurses' work of feeding infants within an increasingly technical organization of NICUs.

SAMPLE

Five primary informants; 18 secondary informants.

DESIGN

The institutional ethnographic approach included field observations, interviews, and phone and e-mail conversations. Our analysis followed accounts of what actually happened within the textual organization of nurses' work.

MAIN OUTCOME

Nurses' feeding practices are directed by protocols that arise within multiple documentation systems and clinical technologies. These systems produce barriers to nurses' efforts to skillfully feed infants.

RESULTS

Prioritization of quality and safety perspectives can obscure and constrain the ordinary yet critical clinical reasoning neonatal nurses employ during feeding work. Clinical technologies that have been developed to improve safety can paradoxically disrupt the ability of nurses to respond in the moment to neonatal feeding cues. This finding provides nurses, leaders, and policymakers with insight into why policies and procedures may not be followed as expected.

A cross-sectional analysis of infant-driven and traditional feeding outcomes for neonatal intensive care unit infants

OBJECTIVE

The goal of this study was to assess the impact of infant-driven feeding (IDF) compared to traditional feeding protocols in promoting earlier successful feeding outcomes.

STUDY DESIGN

We performed a cross-sectional analysis of infants admitted to a level three neonatal intensive care unit (NICU) over a 2-year period. We compared infants fed with the traditional protocol to those under the IDF protocol.

RESULTS

Infants in the IDF group were younger at first feed (p < 0.001). There was no difference in age at nasogastric (NG) tube removal or at discharge, length of stay, or percentage breastfeeding at discharge. There were no differences in outcomes within two subgroups born at <35 and <32 weeks gestation, respectively.

CONCLUSION

The IDF program led to earlier initiation of oral feeding. However, this did not lead to earlier NG tube removal or discharge, a shorter length of stay, or increase in the rates of breastfeeding.

Clinical Validation of the Preterm Oral Feeding Readiness Assessment Scale in Taiwan

PURPOSE

A successful transition from gavage to full oral feeding is a decisive indicator for discharging premature infants from the neonatal intensive care unit. A clinically useful measure of oral feeding readiness would help nurses initiate implementation of the cue-based feeding model in Taiwan. The study aimed to assess the validity and reliability of the Traditional Chinese Preterm Oral Feeding Readiness Assessment Scale (TC-POFRAS).

DESIGN AND METHODS

81 preterm infants were enrolled and assessed by TC-POFRAS regarding their oral feeding readiness. This study included two phases. Phase 1 conducted a cross language validation procedure and item-level content validity indices (I-CVIs) for content validity were estimated. In phase 2, Cronbach's alpha for internal consistency at each category and total scale levels were estimated. A receiver operating characteristic (ROC) curve was estimated to explore the scale's performance. The optimal cut-off value of TC-POFRAS was identified by the best Youden's Index [maximum (sensitivity + specificity - 1)].

RESULTS

All of the I-CVIs were 1.00. The whole Cronbach's alpha for internal consistency was 0.804 (95% CI = 0.736-0.862), and Cronbach's alpha values were between 0.538 (95% = 0.332-0.689) and 0.687 (95%CI = 0.572-0.781) for categories. The area under ROC was 92.2%, and an optimal cut-off value of TC-POFRAS was 29 (sensitivity: 0.938, specificity: 0.941).

CONCLUSIONS

The TC-POFRAS has been verified to be an effective and accurate instrument to determine the initiation of oral feeding in preterm infants.

PRACTICE IMPLICATIONS

The TC-POFRAS is an appropriate and complementary assessment instrument for professionals to conveniently use in clinical practice.

Cue-Based Feeding as Intervention to Achieve Full Oral Feeding in Preterm Infants Primarily Managed with Bubble CPAP

OBJECTIVE

 Cue-based feeding aims at matching introduction of per oral (PO) feeding with physiological readiness of preterm infants to facilitate PO intake and avoid oral aversion. It was claimed that cue-based feeding may lead to delay in the initiation or achieving full PO feeding in clinical setting primarily using bubble nasal continuous positive airway pressure (CPAP). The study aimed to examine the association of cue-based feeding with time of introduction and completing oral feeding in infants primarily managed with bubble CPAP.

STUDY DESIGN

 A retrospective analysis where outcomes of preterm infants ≤32 weeks' gestational age (GA) and ≤2,000 g birth weight (BW) were compared after a practice change from volume-based feeding advancement to cue-based feeding. Continuous variables were compared by using t-test and multilinear regression analysis to control for confounding variables.

RESULTS

 Of the 311 preterm infants who met inclusion and exclusion criteria, 194 were in the cue-based feeding group and 117 were in the volume-based advancement historical comparison group. There were no differences between groups regarding demographic or clinical variables. Postmenstrual age (PMA) of initial feeding assessment was less in the cue-based feeding group. Age of first PO feeding and when some PO was achieved every feed was mildly delayed in the cue-based feeding compared with comparison group, 34 (±1.3) versus 33.7 (±1.2) weeks, and 36.2 (±2.3) versus 36.0 (±2.4) weeks, (p < 0.01) respectively. However, the age of achieving full PO did not differ between groups, 36.8 (±2.2) versus 36.4 (±2.4) weeks (p = 0.13). There was no difference between groups regarding growth parameters at 36 weeks' PMA or at discharge. Similar results were obtained when examining subcategories of infants ≤1,000 g and 1,001 to 2,000 g.

CONCLUSION

 Cue-based feeding may not be associated with a delay in achieving full oral feeding or prolongation of the length of stay in preterm infants managed with CPAP.

KEY POINTS

· Cue-based feeding matches introduction of PO feeding with physiological readiness.. · Cue-based feeding may not be associated with a delay in achieving full oral feeding in preterm infants.. · Cue-based feeding is not associated with prolongation of the length of stay in preterm infants.. · Cue based feeding in preterm infants managed with noninvasive bubble CPAP is examined..

Nonnutritive Sucking Before Oral Feeding of Preterm Infants in Turkey: A Randomized Controlled Study

BACKGROUND

The use of a pacifier is recommended to support sucking reflex during transition from gavage feeding to oral feeding and ensure readiness for feeding.

PURPOSE

A randomized controlled experimental design was used to determine the effect of a pacifier given before feeding on physiological characteristics and feeding performance in preterm infants initially fed orally.

DESIGN AND METHODS

The data were obtained from preterm infants (N = 72) born before 31st gestational week, who were admitted to Newborn Intensive Care Unit of a training and research hospital affiliated with Ministry of Health between January 2017-July 2018 and met the case selection criteria. Heart rates, oxygen saturation levels and feeding performances of preterm infants in both groups before, during, and after feeding were compared.

RESULTS

Heart rates of preterm infants in the experimental group were statistically significantly lower (Experimental: 139.64 ± 10.16; Control: 149.31 ± 8.40; p < 0.01) and their oxygen saturation levels were higher (Experimental: 97.22 ± 2.22; Control: 96.33 ± 1.93; p < 0.05). Feeding efficiency rates (Experimental: 1.94 ± 1.19; Control: 0.69 ± 0.34; p < 0.01) and the percentage of food intake (Experimental: 89.5 ± 23.93; Control: 70.86 ± 27.41; p < 0.01) of newborns in the experimental group were statistically significantly higher and their feeding duration was shorter (Experimental: 10.58 ± 8.29; Control: 16.14 ± 8.31; p < 0.01).

CONCLUSIONS

It was determined that a pacifier given before feeding is effective on regulating physiological parameters and supporting feeding performance in preterm infants.

PRACTICE IMPLICATIONS

The use of a pacifier in the first transition to oral feeding in preterm infants supports their sucking reflex, calms them down, and ensures the readiness for feeding.

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.

Turkish Neonatal Nurses' Knowledge and Practices Regarding the Transition to Oral Feeding in Preterm Infants: A Descriptive, Cross-sectional Study

PURPOSE

Neonatal nurses play an important role in preterm infants' safe and successful transition to oral feeding. Little is known about neonatal nurses' knowledge and practices regarding the transition to oral feeding in preterm infants. The aim of this study was to determine neonatal nurses' knowledge levels and clinical practices related to the process of transitioning preterm infants to oral feeding.

DESIGN AND METHOD

This descriptive cross-sectional study was conducted with 275 neonatal nurses working in the neonatal intensive care units of 9 different hospitals in Istanbul, Turkey. Data were collected using a participant demographic form and a questionnaire about the neonatal nurses' knowledge and practices regarding oral feeding.

RESULTS

The mean knowledge score of the nurses in this study was 64.7 out of 100 (SD = ±8.7; range = 40-87.5). Rates of correct responses were particularly low for items related to cue-based feeding, interventions to promote oral-motor development, non-nutritive sucking, and infant positioning for oral feeding. All of the NICU nurses participating in the study did not use the protocols developed for transitioning preterm infants to oral feeding.

CONCLUSIONS

Nurses need knowledge and practical training on evidence-based therapeutic interventions that promote oral feeding skills in preterm infants during the transition to oral feeding. The use of protocols developed for transitioning preterm infants to oral feeding is limited in NICUs.

PRACTICE IMPLICATIONS

In order to facilitate safe and successful feeding, nurses should improve their knowledge and practical skills regarding the transition to oral feeding and evidence-based therapeutic interventions for preterm infants.

Insights into paediatric tube feeding dependence: A Speech-language pathology perspective

Purpose: To explore possible factors contributing to paediatric tube feeding dependency from the speech-language pathology perspective. Tube feeding dependency can have serious repercussions for children and their families with failed or slow weaning/transitioning from tube to oral feeding, more likely after the age of five.Method: A mixed methods approach was conducted. During the first quantitative phase, an online national survey of speech-language pathologists (SLPs) from the health and non-health sectors was carried out followed by interviews with a subset of the respondents. Forty-three SLPs completed the survey. In the second qualitative phase, 10 participants from the survey were interviewed in depth as to their opinions about why tube dependency occurs. Survey data from phase one were analysed using descriptive statistics and chi square comparisons. Interview data were categorised using thematic analysis. Findings from both methodologies were combined to report the results.Result: Two interlinking meta-themes were identified from the combined data sets. These were: (1) Medicalisation of tube fed children in infancy as a root cause of tube feeding dependency and (2) Fragmentation of the tube fed child's continuity of care. The specific results indicated several possible reasons for tube feeding dependency including medical emphasis on weight gain, prolonged nasogastric tube feeding and waiting too long for transition from tube to oral feeding. A lack of integrated care and clinician confidence in non-health settings also appeared to be a factor contributing to tube feeding dependency.Conclusion: Early and ongoing biomedical focus on weight gain affected long-term goals for transitioning leading, subsequently, to tube feeding becoming normalised by school age.

Individualised developmental care for babies and parents in the NICU: Evidence-based best practice guideline recommendations

Advances in neonatal care have improved survival of premature and critically ill infants; and while rates of some long-term neurodevelopmental problems in survivors have improved, such as cerebral palsy, there are others such as learning and behavioural difficulties that have not. The goal of improving long term neurodevelopmental morbidity has led to an increased focus on improving developmental care not only in neonatal long term follow- up clinics but within the NICU itself to capture the period of earliest brain neuroplasticity. The application of a systematic approach to improve practice is considered the most effective strategy for implementing neuroprotective developmentally supportive care. The content of this paper incorporates evidence-based systematic reviews to guide clinicians in the application of developmentally supportive interventions.

Providing Supportive Hospital Environments to Promote the Language Development of Infants and Children Born Prematurely: Insights From Neuroscience

INTRODUCTION

Rapid neural development occurs beginning in utero and extending throughout a child's first years of life, shaped by environmental input, which is essential for language learning. If this development is disrupted by premature birth and/or related repeated hospitalizations, atypical language development may result even in the absence of severe neurologic damage.

METHOD

This narrative review describes typical neurodevelopment associated with language and the atypical neurodevelopment often experienced by children born prematurely that can adversely affect their language development.

RESULTS

We describe evidence-based intervention strategies applicable in the hospital setting that can support the language development of young children who are born prematurely.

DISCUSSION

To promote neurodevelopmental growth that will support language learning, children born prematurely need to engage in supportive interactions with others. Awareness of evidence-based strategies can equip health care staff to provide a supportive hospital environment to promote the language development of children born premature.

Swallowing behaviours and feeding environment in relation to communication development from early infancy to 6 years of age: a scoping review protocol

INTRODUCTION

Understanding the influences of early swallowing function and feeding environment on the development of communication will enhance prevention and intervention initiatives for young children. This scoping review will help elucidate key elements affecting the developmental trajectory of communicative systems, typically robust and well-developed by formal school entry. We aim to (1) map the current state of the literature in a growing field of interest that has the potential to advance knowledge translation, (2) identify existing gaps and (3) provide research direction for future investigations surrounding feeding-swallowing functions and environment that support or forestall communication development in young children.

METHODS AND ANALYSIS

We are proposing a scoping review to identify the breadth and depth of the existing literature regarding swallowing-feeding functions and environment relative to the onset and progression of communicative behaviours from infancy to 6 (<6;0) years of age. Our protocol delineates rigorous methods according to Arskey and O'Malley's framework and includes elaborations by Levac and colleagues. We will search the literature based on 10 databases, 17 peer-reviewed journals, 4 conference proceedings and 6 grey literature sources. Two authors will independently screen abstracts and review full articles, remaining blind to each other's results. A third author will contribute to resolving any discrepant results from both the abstract and article review. Subsequently, we will extract data and chart information from accepted articles using a pre-established data collection form. We will stratify results according to healthy versus impaired swallowing-feeding functions and communication development.

ETHICS AND DISSEMINATION

Our scoping review does not require ethical approval. We will disseminate our final study results through international and national conference presentations, publication in a peer-reviewed journal and knowledge translation activities with stakeholders.

Reducing toxic stress in the neonatal intensive care unit to improve infant outcomes

In 2011, the American Academy of Pediatrics (AAP) published a technical report on the lifelong effects of early toxic stress on human development, and included a new framework for promoting pediatric health: the Ecobiodevelopmental Framework for Early Childhood Policies and Programs. We believe that hospitalization is a specific form of toxic stress for the neonatal patient, and that toxic stress must be addressed by the nursing profession in order to substantially improve outcomes for the critically ill neonate. Approximately 4% of normal birthweight newborns and 85% of low birthweight newborns are hospitalized each year in the highly technological neonatal intensive care unit (NICU). Neonates are exposed to roughly 70 stressful procedures a day during hospitalization, which can permanently and negatively alter the infant's developing brain. Neurologic deficits can be partly attributed to the frequent, toxic, and cumulative exposure to stressors during NICU hospitalization. However, the AAP report does not provide specific action steps necessary to address toxic stress in the NICU and realize the new vision for pediatric health care outlined therein. Therefore, this paper applies the concepts and vision laid out in the AAP report to the care of the hospitalized neonate and provides action steps for true transformative change in neonatal intensive care. We review how the environment of the NICU is a significant source of toxic stress for hospitalized infants. We provide recommendations for caregiving practices that could significantly buffer the toxic stress experienced by hospitalized infants. We also identify areas of research inquiry that are needed to address gaps in nursing knowledge and to propel nursing science forward. Finally, we advocate for several public policies that are not fully addressed in the AAP technical report, but are vital to the health and development of all newborns.

Does the Infant-Driven Feeding Method Positively Impact Preterm Infant Feeding Outcomes?

BACKGROUND

Achievement of independent oral feeding is a major determinant of discharge and contributes to long lengths of stay. Accumulating evidence suggests that there is great variation between and within newborn intensive care units in the initiation and advancement of oral feeding. The Infant-Driven Feeding (IDF) method is composed of 3 behavioral assessments including feeding readiness, quality of feeding, and caregiver support. Each assessment includes 5 categories and is intended as a method of communication among caregivers regarding the infant's readiness and progression toward independent oral feeding.

PURPOSE

To identify and summarize the available evidence on the use of the IDF method at initiation of oral feeds, time to independent oral feedings, and length of stay in the newborn intensive care unit or level II nursery for preterm infants.

METHODS/SEARCH STRATEGY

Four databases including CINAHL, Medline/PubMed, Ovid Nursing, and Embase were searched for "infant guided feedings," "infant driven feeding," "cue-based feeding," and "co regulated feeding." The full text of 32 articles was reviewed to identify experimental, quasiexperimental, or retrospective design to assess the evidence related to cue-based feeding.

FINDINGS

There were no randomized control, quasi-experimental, or retrospective studies utilizing the IDF method. There were 3 quality improvement projects utilizing the IDF method. The findings were conflicting: 1 project found the IDF method favorable in the achievement of full oral feedings, 2 projects found the IDF method favorable for reducing length of stay, and 1 project did not find differences in initiation, achievement of oral feedings, or length of stay.

IMPLICATIONS FOR PRACTICE

There is scant evidence limited to quality improvement projects to support the use of the IDF method.

IMPLICATIONS FOR RESEARCH

Research is needed to empirically validate the IDF method and to inform practice related to the initiation and advancement of oral feeding for preterm infants.

Quantifying the Impact of Common Feeding Interventions on Nutritive Sucking Performance Using a Commercially Available Smart Bottle

An estimated 25% to 40% of infants experience difficulties with learning to breast- or bottle-feed. Yet, guidelines and evidence-based support for common feeding practices are limited. The objective of this case report was to quantify the impact of feeding interventions on nutritive sucking performance after discharge in an outpatient setting. This observational case series involved 2 infants. To determine the impact of cumulative interventions, pre- and postintervention effect sizes were calculated. Sucking performance metrics of interest included nipple movement peak sucking amplitude, duration, frequency, and smoothness. Interventions included positional changes and changes in nipple flow rate, among others. For both infants, cumulative interventions had the greatest impact on suck frequency; postintervention, infants were able to increase their rate of nutritive sucking per burst. Other aspects of sucking performance were differentially impacted for each baby. Researchers agree that neonatal and infant feeding has been understudied and that the evidence for common interventions needs to be strengthened. We have demonstrated the implementation of readily available technology that can be used to quantify the direct impact of any intervention on actual sucking performance. In doing so, we can individualize care to support skill development and improve outcomes for infants at risk for ongoing feeding challenges.

Systematic Review of Quality Improvement Initiatives Related to Cue-Based Feeding in Preterm Infants

OBJECTIVE

To examine and synthesize the outcomes of quality improvement (QI) initiatives related to cue-based feeding of preterm infants to facilitate implementation of findings to improve nursing practice.

DATA SOURCES

Cumulative Index of Nursing and Allied Health Literature (CINAHL) Complete and PubMed were searched for full-text articles published from 2000 through 2017 included under the medical subject heading quality improvement and whose titles included any form of the term feeding combined with any of the following: bottle, breast, cue-based, demand, infant, neonate, newborn, oral, or responsive.

STUDY SELECTION

Articles were considered for inclusion if they were published in English-language journals and focused on QI initiatives concerning cue-based feeding of preterm infants in NICU settings.

DATA EXTRACTION

After initial article review, we examined clinical outcomes and assessed study methodology using the Quality Improvement Minimum Quality Criteria Set (QI-MQCS) framework.

DATA SYNTHESIS

Our review yielded seven studies related to cue-based feeding of preterm infants. Five studies included multidisciplinary stakeholder teams to assess their respective NICU environments and facilitate project completion. In two studies, feeding "champions" were designated as facilitators. In one study, researchers used a Plan-Do-Study-Act approach and emphasized process over outcome. In six studies, researchers measured hospital length of stay, which decreased in five intervention groups. In three studies, researchers measured infant weight gain, which increased in two intervention groups. In two studies, researchers monitored weight gain velocity, and in five studies, researchers reported earlier gestational attainment of full oral feedings.

CONCLUSION

Weight gain, time to full oral feedings, and hospital length of stay may be improved with the use of cue-based feeding. QI initiatives are a practical means to bring best evidence and multidisciplinary collaboration to the NICU.

Effects of early intervention on feeding behavior in preterm infants: A randomized controlled trial

BACKGROUND

Although highly beneficial, human milk feeding is challenging in preterm infants due to adverse NICU factors for the infant and mother.

AIM

To investigate the effects of an early intervention in promoting infant's human milk feeding and acquisition of full oral feeding.

METHODS

This study is part of a RCT. We included preterm infants born between 25⁺⁰ and 29⁺⁶ weeks of gestational age (GA) without severe morbidities, and their parents. Infants were randomized to either receive early intervention (EI) or standard care (SC). EI included PremieStart and parental training to promote infant massage and visual attention according to a detailed protocol. SC, in line with NICU protocols, included Kangaroo Mother Care. The time of acquisition of full oral feeding and human milk consumption at discharge were recorded.

RESULTS

Seventy preterm (EI n = 34, SC n = 36) infants were enrolled. Thirteen were excluded according to the protocol. Fifty-seven (EI n = 29, SC n = 28) infants were evaluated at discharge. The two groups were comparable for parent and infant characteristics. A significantly higher rate of infants fed with any human milk was observed in the EI group (75.9%) compared with the SC group (32.1%) (p = 0.001), and EI infants were four times more likely to be fed exclusively with human milk. Full oral feeding was achieved almost one week earlier in EI infants (mean postmenstrual age 36.8 ± 1.6 vs 37.9 ± 2.4 weeks in EI vs SC, p = 0.04).

CONCLUSIONS

Early interventions promoting mother self-efficacy and involvement in multisensory stimulation have beneficial effects on human milk feeding in preterm infants.

Clinicians guide for cue-based transition to oral feeding in preterm infants: An easy-to-use clinical guide

RATIONALE, AIMS AND OBJECTIVES

This article aims to provide evidence to guide multidisciplinary clinical practitioners towards successful initiation and long-term maintenance of oral feeding in preterm infants, directed by the individual infant maturity.

METHOD

A comprehensive review of primary research, explorative work, existing guidelines, and evidence-based opinions regarding the transition to oral feeding in preterm infants was studied to compile this document.

RESULTS

Current clinical hospital practices are described and challenged and the principles of cue-based feeding are explored. "Traditional" feeding regimes use criteria, such as the infant's weight, gestational age and being free of illness, and even caregiver intuition to initiate or delay oral feeding. However, these criteria could compromise the infant and increase anxiety levels and frustration for parents and caregivers. Cue-based feeding, opposed to volume-driven feeding, lead to improved feeding success, including increased weight gain, shorter hospital stay, fewer adverse events, without increasing staff workload while simultaneously improving parents' skills regarding infant feeding. Although research is available on cue-based feeding, an easy-to-use clinical guide for practitioners could not be found. A cue-based infant feeding regime, for clinical decision making on providing opportunities to support feeding success in preterm infants, is provided in this article as a framework for clinical reasoning.

CONCLUSIONS

Cue-based feeding of preterm infants requires care providers who are trained in and sensitive to infant cues, to ensure optimal feeding success. An easy-to-use clinical guideline is presented for implementation by multidisciplinary team members. This evidence-based guideline aims to improve feeding outcomes for the newborn infant and to facilitate the tasks of nurses and caregivers.

Parent perception of the impact of using thickened fluids in children with dysphagia

BACKGROUND

Oropharyngeal dysphagia occurs in children without known neurological disorders, increasing their risk for respiratory problems and inadequate intake. Clinicians may recommend thickening nutritive fluids; however, there is little research regarding the impact of thickening nutritive fluids on clinical outcomes in children.

METHODS

We used a parental reporting tool to determine whether parents identified changes in signs of dysphagia or volume of intake when thickened fluids were incorporated into an individualized feeding program for dysphagic children without known neurological problems. Fifty-five children diagnosed with dysphagia, for whom thickened fluids had been recommended per radiographic and clinical exam, qualified for the study. Parents of 44 children (24 females, 20 males) aged 2 weeks to 14 months completed baseline and post-thickening (within 90 days) rating scales.

RESULTS

Compared to baseline, parents reported significant decreases in the frequency of apnea (W = -219, P < 0.0001, r = 0.399), congestion (W = -450, P < 0.0001, r = 0.579), coughing/choking with drinking (W = -485, P < 0.0001, r = 0.603), resistance to feeding (W = -344.5, P < 0.0001, r = 0.476), vomiting during feeding (W = -409, P < 0.0001, r = 0.565), and wheezing (W = -337, P < 0.001, r = 0.449). For those children whose parents initially reported inadequate levels of intake, there was a significant (Z = 3.15, P = 0.0029, r = 0.47) increase (+49.63 mm) in the rated adequacy of liquid intake, as well as a significant increase (+1.41 oz.) in the estimated volume per feeding (Z = 224, P = 0.29, r = 0.33).

CONCLUSION

These results provide information for clinicians and physicians to incorporate when considering the use of thickened fluids in the dysphagia management of children without a known neurological diagnosis.

Quantifying Neonatal Sucking Performance: Promise of New Methods

Neonatal feeding has been traditionally understudied so guidelines and evidence-based support for common feeding practices are limited. A major contributing factor to the paucity of evidence-based practice in this area has been the lack of simple-to-use, low-cost tools for monitoring sucking performance. We describe new methods for quantifying neonatal sucking performance that hold significant clinical and research promise. We present early results from an ongoing study investigating neonatal sucking as a marker of risk for adverse neurodevelopmental outcomes. We include quantitative measures of sucking performance to better understand how movement variability evolves during skill acquisition. Results showed the coefficient of variation of suck duration was significantly different between preterm neonates at high risk for developmental concerns (HRPT) and preterm neonates at low risk for developmental concerns (LRPT). For HRPT, results indicated the coefficient of variation of suck smoothness increased from initial feeding to discharge and remained significantly greater than healthy full-term newborns (FT) at discharge. There was no significant difference in our measures between FT and LRPT at discharge. Our findings highlight the need to include neonatal sucking assessment as part of routine clinical care in order to capture the relative risk of adverse neurodevelopmental outcomes at discharge.

[Hospital discharge criteria for very low birth weight newborns]

Hospital discharge criteria for the pre-term newborn are mainly based on physiological competences (thermoregulation, respiratory stability, and feeding skills), although family support and ability to care for the baby, as well as a well-planned discharge are also cornerstones to ensure a successful discharge. In this article, the Committee of Standards of the Spanish Society of Neonatology reviews the current hospital discharge criteria in order for it to be useful as a clinical guide in Spanish neonatal units.

Facilitators and barriers of breastfeeding late preterm infants according to mothers' experiences

BACKGROUND

Late preterm infants account for the majority of preterm births. They are at an increased risk of neonatal mortality and morbidity and are less likely to initiate breastfeeding and to be exclusively breastfed at discharge compared to infants born at term. The aim of this study was to identify the facilitators and barriers to breastfeeding during hospital stays according to the experiences of mothers of late preterm infants.

METHODS

We conducted a cross-sectional questionnaire survey. Mothers who intended to breastfeed and had given birth to a newborn admitted to level I and II care, with a gestational age of 34 0/7 to 36 6/7 weeks, were enrolled. Sociodemographic data, neonatal variables, mode of feeding and feeding status at discharge were also collected.

RESULTS

A total of 92 mothers who had given birth to 121 infants were enrolled. At discharge, any human milk was fed to 94 % of infants, with exclusively human milk being fed in 43 % of cases; exclusively formula was fed to 6 % of infants. In the multivariate analysis, having expressed breast milk was independently associated with an increased risk of being fed with either any human milk or formula only (OR = 2.73, 95 % CI 1.05-7.1, p = 0.039), whereas being encouraged to practice kangaroo mother care tended to have a protective effect (OR = 0.46, 95 % CI 0.2-1.06, p = 0.07).

CONCLUSIONS

Based on the present findings, health care professionals should strive to fully implement breastfeeding support for mothers of late preterm infants who intend to breastfeed, in particular optimizing breast milk expression and promoting kangaroo mother care. Further studies are needed to gain further insight into the complex interplay of the factors that modulate breastfeeding outcome in late preterm infants.

Cue-Based Feeding in the NICU

In NICU settings, caring for neonates born as early as 23 weeks gestation presents unique challenges for caregivers. Traditionally, preterm infants who are learning to orally feed take a predetermined volume of breast milk or formula at scheduled intervals, regardless of their individual ability to coordinate each feeding. Evidence suggests that this volume-driven feeding model should be replaced with a more individualized, developmentally appropriate practice. Evidence from the literature suggests that preterm infants fed via cue-based feeding reach full oral feeding status faster than their volume-feeding counterparts and have shorter lengths of stay in the hospital. Changing practice to infant-driven or cue-based feedings in the hospital setting requires staff education, documentation, and team-based communication.

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.
