Randomized clinical trial investigating the effect of consistent, developmentally-appropriate, and evidence-based multisensory exposures in the NICU

Description and evidence on the supporting and enhancing neonatal intensive care unit sensory experiences (SENSE) program

AIM

To describe the supporting and enhancing neonatal intensive care unit (NICU) sensory experiences (SENSE) program, associated research and opportunities for further study.

METHODS

A review of current materials on SENSE program implementation, publications related to SENSE development, and research on program implementation and patient outcomes was conducted to describe the SENSE program and its associated research.

RESULTS

The SENSE program combines structured, evidence-based, multisensory interventions with parent engagement in order to optimise outcomes in the complex NICU environment. Through a stepwise and scientific process, the SENSE program was developed to include specific doses and targeted timing (based on the infant's postmenstrual age, PMA) of evidence-based interventions such as massage, auditory exposure, rocking, holding and skin-to-skin care for parents to provide their infants each day of NICU hospitalisation. It is adapted in context of concurrent medical interventions, infant behavioural responses, as well as NICU culture. The program is feasible to implement, acceptable to staff, and related to infants receiving more developmentally appropriate sensory exposures. Adaptations related to NICU culture and parent involvement have been reported. Research has identified relationships of the SENSE program to improved parent confidence, neurobehaviour and feeding at term age as well as improved communication 1 year of age.

CONCLUSION

The literature related to the SENSE program is promising, but more research on efficacy and implementation is needed.

Environment Enrichment Strategies for Pre- and Post-Term Infants: A Summarized Communication From Pediatric Physical Therapists

PURPOSE

Environmental enrichment (EE) represents a dynamic approach to enhance infants' cognitive and motor development through augmented environment with stimulating, novel opportunities. Despite the recognized benefits of EE on neuromotor outcomes, its integration into early physical therapy interventions for infants at risk of neuromotor delays and disabilities remains under-defined and inconsistently applied in standard practice. This gap underscores the necessity for comprehensive guidance to systematically incorporate EE into early intervention programs and daily routines.

SUMMARY OF KEY POINTS

This paper provides a preliminary framework for the integration of EE into the clinical and home environments for infants from birth to 1 year of age.

RECOMMENDATIONS FOR PRACTICE

With the 7 key components of EE, including sensory system stimulation (auditory, proprioceptive, tactile, vestibular, and visual stimulations), cognitive challenges, and social engagement, this framework aims to maximize cognitive and motor development for infants at both pre and post-term age by leveraging the principles of EE(Supplemental Digital Content,Video, available at: http://links.lww.com/PPT/A624 ).

Developmental trajectories in high-risk NICU graduates during the first year of life

OBJECTIVE

We examined whether early medical factors predicted variability in developmental level and trajectories in high-risk neonatal intensive care unit (NICU) graduates during the first year of life.

METHOD

Infants (n = 53) who met criteria for the High-Risk Infant Follow-up Program were enrolled. Simple linear models predicted 12-month developmental abilities and linear mixed models predicted 6- to 12-month trajectories based on length of NICU stay and birthweight.

RESULTS

Length of NICU stay was more clearly predictive of 12-month developmental level, while birthweight better explained variability in trajectories. Communication and daily living skills varied based on early medical factors, whereas social skills did not. Motor skills varied by length of stay but not birthweight.

CONCLUSION

Results support the need for close developmental monitoring of NICU graduates, particularly those with lengthier stays and lower birthweight. Developmental support needs should be based not just on current delays, but on the rate at which infants learn new skills.

Enhancing Sensory Experiences for Infants Born Preterm: A Quality Improvement Project

Objective

To enhance neonatal sensory experiences in infants born preterm: a quality improvement project.

Design

This was a time-interruption quality improvement project. The time-interruption lasted 4 weeks with an 8-week data collection period before and after. Baseline data were collected on current program use for 8 weeks prior to the time interruption. The neonatal intensive care unit (NICU) occupational therapist provided staff education, training, and modeling of the Supporting and Enhancing NICU Sensory Experiences (SENSE) program during the time interruption. Data were collected for 8 weeks after the time interruption to track improvements.

Participants

Twenty infants and their families participated, as well as NICU nurses who provided positive sensory experiences and completed surveys.

Main Outcome Measures

Data related to delivery of, education on, and adherence to SENSE were collected before, during, and after the time interruption. Staff surveys were completed pre- and posteducation, training, and modeling to gather perspectives on program usage.

Results

On average, parents delivered 43.88 minutes of positive sensory input per day before and increased to 92.7 minutes per day after the time interruption. Positive tactile recommendations were met, on average, 19% of the time before and 47% of the time after the time interruption. After education, training and modeling, nursing staff unanimously supported the program according to surveys.

Conclusions

Although a higher percentage of infants received the recommended dosage of positive tactile input after intervention, opportunities still exist to improve and expand implementation.

Optimal presence: enhancing parent integration to maximize neurodevelopmental outcomes in preterm infants

Preterm birth disrupts the natural progression of events in the parent-infant relationship and bestows many of the typical parent responsibilities to the clinical care team. In turn, the neonatal intensive care environment (NICU) introduces obstacles to parents that would not otherwise be encountered and forces parents to adapt to this artificial environment as they seek to bond with and care for their newborn. Facilitating parent presence at the bedside and incorporating them into the care of their preterm infant is critical for lessening the immediate burden to both the parent and offspring while also ensuring the best possible outcome for preterm infants. In this review, we explore the impact that parents exert on the neurodevelopmental outcome of preterm infants and identify several barriers and facilitators to parent presence.

Eligible Infants Included in Neonatal Clinical Trials and Reasons for Noninclusion: A Systematic Review

Importance

Results of clinical trials can only represent included participants, and many neonatal trials fail due to insufficient participation. Infants not included in research may differ from those included in meaningful ways, biasing the sample and limiting the generalizability of findings.

Objective

To describe the proportion of eligible infants included in neonatal clinical trials and the reasons for noninclusion.

Evidence Review

A systematic search of Cochrane CENTRAL was performed by retrieving articles meeting the following inclusion criteria: full-length, peer-reviewed articles describing clinical trial results in at least 20 human infants from US neonatal intensive care units, published in English, and added to Cochrane CENTRAL between 2017 and 2022. Retrieved articles were screened for inclusion by 2 independent researchers.

Findings

In total 120 articles met inclusion criteria and 91 of these (75.8%) reported the number of infants eligible for participation, which totaled 26 854 in aggregate. Drawing from these, an aggregate of 11 924 eligible infants (44.4%) were included in reported results. Among all eligible infants, most reasons for noninclusion in results were classified as modifiable or potentially modifiable by the research team. Parents declining to participate (8004 infants [29.8%]) or never being approached (2507 infants [9.3%]) were the 2 predominant reasons for noninclusion. Other modifiable reasons included factors related to study logistics, such as failure to appropriately collect data on enrolled infants (859 of 26 854 infants [3.2%]) and other reasons (1907 of 26 854 infants [7.1%]), such as loss to follow-up or eligible participants that were unaccounted for. Nonmodifiable reasons, including clinical change or death, accounted for a small proportion of eligible infants who were not included (858 of 26 854 infants [3.2%]).

Conclusions and Relevance

This systematic review of reporting on eligible infants included and not included in neonatal clinical trials highlights the need for improved documentation on the flow of eligible infants through neonatal clinical trials and may also inform recruitment expectations for trialists designing future protocols. Improved adherence to standardized reporting may clarify which potential participants are being missed, improving understanding of the generalizability of research findings. Furthermore, these findings suggest that future work to understand why parents decline to participate in neonatal research trials and why some are never approached about research may help increase overall participation.

A Scoping Review of Multimodal, Dyadic Early Relational Health Interventions in NICUs in the United States

BACKGROUND

Early relational health (ERH) interventions can buffer toxic stress and improve the developmental trajectories of neonatal intensive care unit (NICU) infants.

PURPOSE

The purpose was to examine the current state of the science related to multimodal, dyadic ERH interventions implemented in the NICU setting in the United States and identify gaps in the current literature.

DATA SOURCES

PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and PsycInfo were searched in November 2022 and November 2023 for original studies and conference proceedings from 1970 to present in the English language. Gray literature searches were performed in February 2023 and December 2023.

STUDY SELECTION

English language, original research, with a focus on multimodal, dyadic ERH interventions that took place primarily in a NICU in the United States were included. Outcome measures could be related to implementation, relational health, or physical and/or mental health outcomes of parent and/or infant. Eighteen of 2021 reviewed articles met the inclusion criteria.

DATA EXTRACTION

Data were extracted for author, year, intervention, purpose, methods, sample, paternal inclusion, dyadic components, non-dyadic components, and major outcomes/results and distilled for study characteristics, multimodal, dyadic intervention characteristics, and outcome measures.

RESULTS

Several multimodal dyadic interventions exist to aid ERH in the NICU, providing evidence of improved outcomes for infants and families. More research is required using higher sample sizes and replication studies.

IMPLICATIONS FOR PRACTICE AND RESEARCH

ERH interventions show promise in improving neurodevelopmental, behavioral, and maternal mental health outcomes and should be considered for implementation into NICU services.

Comparative utility of MRI and EEG for early detection of cortical dysmaturation after postnatal systemic inflammation in the neonatal rat

BACKGROUND

Exposure to postnatal systemic inflammation is associated with increased risk of brain injury in preterm infants, leading to impaired maturation of the cerebral cortex and adverse neurodevelopmental outcomes. However, the optimal method for identifying cortical dysmaturation is unclear. Herein, we compared the utility of electroencephalography (EEG), diffusion tensor imaging (DTI), and neurite orientation dispersion and density imaging (NODDI) at different recovery times after systemic inflammation in newborn rats.

METHODS

Sprague Dawley rat pups of both sexes received single-daily lipopolysaccharide (LPS; 0.3 mg/kg i.p.; n = 51) or saline (n = 55) injections on postnatal days (P)1, 2, and 3. A subset of these animals were implanted with EEG electrodes. Cortical EEG was recorded for 30 min from unanesthetized, unrestrained pups at P7, P14, and P21, and in separate groups, brain tissues were collected at these ages for ex-vivo MRI analysis (9.4 T) and Golgi-Cox staining (to assess neuronal morphology) in the motor cortex.

RESULTS

Postnatal inflammation was associated with reduced cortical pyramidal neuron arborization from P7, P14, and P21. These changes were associated with dysmature EEG features (e.g., persistence of delta waveforms, higher EEG amplitude, reduced spectral edge frequency) at P7 and P14, and higher EEG power in the theta and alpha ranges at P21. By contrast, there were no changes in cortical DTI or NODDI in LPS rats at P7 or P14, while there was an increase in cortical fractional anisotropy (FA) and decrease in orientation dispersion index (ODI) at P21.

CONCLUSIONS

EEG may be useful for identifying the early evolution of impaired cortical development after early life postnatal systemic inflammation, while DTI and NODDI seem to be more suited to assessing established cortical changes.

Multisensory stimulation for promoting development and preventing morbidity in preterm infants

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of multisensory stimulation compared to any single sensory intervention or standard care for physical and neurological development in preterm infants.

White Matter Injury on Early-versus-Term-Equivalent Age Brain MRI in Infants Born Preterm

BACKGROUND AND PURPOSE

White matter injury in infants born preterm is associated with adverse neurodevelopmental outcomes, depending on the extent and location. White matter injury can be visualized with MR imaging in the initial weeks following preterm birth but is more commonly defined at term-equivalent-age MR imaging. Our aim was to see how white matter injury detection in MR imaging compares between the 2 time points.

MATERIALS AND METHODS

This study compared white matter injury on early brain MR imaging (30-34 weeks' postmenstrual age) with white matter injury assessment at term-equivalent (37-42 weeks) MR imaging, using 2 previously published and standardized scoring systems, in a cohort of 30 preterm infants born at <33 weeks' gestational age.

RESULTS

There was a strong association between the systematic assessments of white matter injury at the 2 time points (P = .007) and the global injury severity (P < .001).

CONCLUSIONS

Although the optimal timing to undertake neuroimaging in the preterm infant remains to be determined, both early (30-34 weeks) and term-equivalent MR imaging provide valuable information on white matter injury and the risk of associated sequelae.

Visual stimulation in the neonatal intensive care unit: A systematic literature review

We aimed to systematically categorize evidence on the types of early visual stimulation applied to preterm infants (PTIs) admitted to neonatal intensive care units (NICUs), aiming to improve visual function parameters. This study was conducted according to PRISMA and registered in PROSPERO with CRD42022333753. Last search was conducted on March 15, 2023, in four different databases. Articles written in English, Portuguese, Spanish, or Italian, and available in full text were included. Two independent authors performed study selection, data extraction, and bias risk assessment. If there was any disagreement, a third author was contacted. A total of eight studies were included. From these, 62.5% presented a low risk of bias. 100% used a multisensory intervention, which included visual stimulation. In 50%, visual intervention consisted of black and white stimulation cards placed inside the incubator for three minutes. The outcomes showed positive benefits in visual function parameters and other reported clinical benefits in breastfeeding and neuromuscular development. This review demonstrated there is still scarce literature on the effects of early visual stimulation on purely visual functional outcomes, although the existing findings are promising. Parental involvement has been generating unquestionable benefits for the binomial mother-infant and gaining greater acceptance by health professionals.

Organizational Barriers to and Facilitators of the Successful Implementation and Sustainability of the Supporting and Enhancing NICU Sensory Experiences (SENSE) Program

IMPORTANCE

The Supporting and Enhancing NICU Sensory Experiences (SENSE) program is an evidence-based intervention that promotes daily, positive sensory exposures for infants in the neonatal intensive care unit (NICU). Understanding program implementation across sites may aid in optimizing strategies for uptake of the program and subsequently improve outcomes for infants and families.

OBJECTIVE

To investigate health care professionals' perceptions of implementing the SENSE program.

DESIGN

The SENSE Program Implementation Survey was developed using Proctor et al.'s model and the BARRIERS scale to probe organizational practices across sites worldwide.

SETTING

Survey distributed to 211 hospitals with a SENSE program license obtained before March 2020.

PARTICIPANTS

One hundred fourteen NICU personnel (response rate = 54%).

OUTCOMES AND MEASURES

The survey sought to understand barriers and facilitators, adaptations during implementation, and associated costs.

RESULTS

Of the 53% (n = 57 of 107) of respondents who had implemented the SENSE program, many (n = 14; 31%) experienced quick timing (<1 mo) to use, including spread to nearly all infants in their NICU within 6 mo (n = 18; 35%). Most reported the program was used to educate families ≤3 days of birth (n = 20/59; 34%). Most of the sensory interventions in the program were performed by parents (n = 38; 67%) and therapists (n = 44; 77%). Barriers and facilitators at the organizational and individual levels were identified. No additional staff were hired to implement the program.

CONCLUSIONS AND RELEVANCE

Given perceived successes and challenges, strategic enhancement of implementation can inform future administrations of the SENSE program. Plain-Language Summary: This study provides occupational therapists who are interested in implementing the SENSE program (Supporting and Enhancing NICU Sensory Experiences) with an understanding of common barriers, facilitators, costs, and adaptations, which can be used to advocate for program implementation in NICUs to improve outcomes for preterm infants worldwide.

Infant and Parent Outcomes Related to NICU-Based Co-occupational Engagement

Neonatal intensive care unit (NICU) co-occupations may impact parent-infant outcomes. The main objective of this study was to explore relationships between parent and infant outcomes based on whether sensory-based interventions (co-occupations) occurred most often between parent-infant dyads or provider/volunteer-infant dyads. Thirty-five families received the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, which includes education defining specific amounts of sensory exposures for infants to receive each day of NICU hospitalization (with a preference for parent delivery). Infant sensory experiences in the NICU were logged, and dyads were grouped based on who conducted most of the sensory interventions with the infant in the NICU into a Parent-Infant Co-occupation group or Other Administered group. The Parent-Infant Co-occupation group had infants with less lethargy on the NICU Network Neurobehavioral Scale (p = .04), and parents with lower scores on the Parental Stress Scale (p = .003) and State-Trait Anxiety Inventory-state (p = .047). Parent-infant engagement in co-occupations was related to parental mental health and infant neurobehavior.

Race and Ethnicity of Infants Enrolled in Neonatal Clinical Trials: A Systematic Review

Importance

Representativeness of populations within neonatal clinical trials is crucial to moving the field forward. Although racial and ethnic disparities in research inclusion are well documented in other fields, they are poorly described within neonatology.

Objective

To describe the race and ethnicity of infants included in a sample of recent US neonatal clinical trials and the variability in this reporting.

Evidence Review

A systematic search of US neonatal clinical trials entered into Cochrane CENTRAL 2017 to 2021 was conducted. Two individuals performed inclusion determination, data extraction, and quality assessment independently with discrepancies adjudicated by consensus.

Findings

Of 120 studies with 14 479 participants that met the inclusion criteria, 75 (62.5%) included any participant race or ethnicity data. In the studies that reported race and ethnicity, the median (IQR) percentage of participants of each background were 0% (0%-1%) Asian, 26% (9%-42%) Black, 3% (0%-12%) Hispanic, 0% (0%-0%) Indigenous (eg, Alaska Native, American Indian, and Native Hawaiian), 0% (0%-0%) multiple races, 57% (30%-68%) White, and 7% (1%-21%) other race or ethnicity. Asian, Black, Hispanic, and Indigenous participants were underrepresented, while White participants were overrepresented compared with a reference sample of the US clinical neonatal intensive care unit (NICU) population from the Vermont Oxford Network. Many participants were labeled as other race or ethnicity without adequate description. There was substantial variability in terms and methods of reporting race and ethnicity data. Geographic representation was heavily skewed toward the Northeast, with nearly one-quarter of states unrepresented.

Conclusions and Relevance

These findings suggest that neonatal research may perpetuate inequities by underrepresenting Asian, Black, Hispanic, and Indigenous neonates in clinical trials. Studies varied in documentation of race and ethnicity, and there was regional variation in the sites included. Based on these findings, funders and clinical trialists are advised to consider a 3-point targeted approach to address these issues: prioritize identifying ways to increase diversity in neonatal clinical trial participation, agree on a standardized method to report race and ethnicity among neonatal clinical trial participants, and prioritize the inclusion of participants from all regions of the US in neonatal clinical trials.

Multisensory stimulation bundles on sleep and neurobehavioral development in the first year after birth in very preterm infants: a randomized crossover controlled study protocol

BACKGROUND

Disrupted sleep is believed to contribute to short- and long-term neurodevelopmental problems in very preterm infants (VPIs). This study presents a protocol for an evaluator-blinded, randomized crossover trial. It aims to assess the sleep efficiency of hospitalized VPIs by providing multisensory stimulation bundles. Furthermore, it aims to observe the intervention impacts on sleep during hospitalization of the VPIs and their sleep and neurodevelopmental outcomes during the first year of post-discharge follow-up.

METHODS

The study will be conducted in the neonatology department of a tertiary pediatric teaching hospital. All the eligible VPIs will undergo two types of care in random order: "standard care" (2 weeks) and "standard care plus multisensory stimulation bundles," each lasting 2 weeks. A generated list of random numbers will be used for case sequence allocation. Sleep outcomes will be evaluated using the Actiwatch-2 Actigraph. Moreover, the amplitude-integrated electroencephalography and the Griffiths Mental Development Scales will be used to measure the neurodevelopmental outcomes during hospitalization and in the first year of follow-up of the VPIs.

DISCUSSION

The intervention protocol of this study differs from that of other traditional interventions by producing precise and consistent supportive stimulations, similar to maternal tactile, auditory, posture, and visual effects for hospitalized VPIs. This protocol could be an effective measure to facilitate sleep and early neurodevelopment of VPIs. The expected outcomes will help confirm the implementation and generalization of the multisensory stimulation bundles' care protocol in neonatology departments. We expect that the study will positively impact hospitalized VPIs, especially in their sleep and early neurodevelopmental outcomes. It will also provide a new perspective regarding parent and infant interaction strategies, particularly for newborn intensive care units that limit visits because of the global spread of COVID-19.

Serial neuroimaging of brain growth and development in very preterm infants receiving tailored neuropromotive support in the NICU. Protocol for a prospective cohort study

Introduction

Children born very preterm (VP) remain at risk for long-term neurodevelopmental impairment. Patterns of brain growth and injury, and how early neuropromotive therapies might mitigate developmental risk in VP infants remain insufficiently understood.

Methods

This is a prospective cohort study of VP infants born at/before 32 weeks gestation. The study will enroll n = 75 consecutively-born VP infants in a level-III NICU. Exposed infants will be categorized into two groups (group 1: low-risk, n = 25 or group 2: high-risk, n = 25) based on the degree of neurological injury on early brain magnetic resonance imaging (MRI) at enrollment. Infants in the low-risk group (i.e., without significant injury defined as intraventricular hemorrhage with dilation, moderate or severe white matter injury, or cerebellar hemorrhage) will receive neurodevelopmental support utilizing the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, while infants in the high-risk group (with neurological injury) will receive more intensive neurorehabilitative support (SENSE-plus). Age-specific, tailored sensory experiences will be facilitated contingently, preferentially by the infant's family with coaching from NICU staff. VP infants in exposure groups will undergo a brain MRI approximately every 2 weeks from enrollment until term-equivalent to monitor brain growth and evolution of injury. Exposed infants will be compared with a reference group (group 3: n = 25), i.e. VP infants whose families decline initial enrollment in SENSE, and subsequently undergo a term-equivalent brain MRI for other purposes. The primary aim of this study is characterization of term-equivalent brain growth and development among VP infants receiving NICU-based neuropromotive interventions compared to VP infants receiving the standard of care. Secondary aims include defining the timing and factors associated with total and regional brain growth on serial brain MRI among VP infants, (Aim 2), and using early imaging to tailor developmental intervention in the NICU while exploring associations with outcomes in VP infants at discharge and at two years corrected age (Aim 3).

Discussion

This study will address gaps in understanding patterns of brain growth and injury drawing on serial MRI of hospitalized VP infants. These data will also explore the impact of intensive, tailored neuropromotive support delivered prior to term-equivalent on child and family outcomes.

Prenatal and perinatal factors associated with neonatal neurobehavioral profiles in the ECHO Program

BACKGROUND

Single-cohort studies have identified distinct neurobehavioral profiles that are associated with prenatal and neonatal factors based on the NICU Network Neurobehavioral Scale (NNNS). We examined socioeconomic, medical, and substance use variables as predictors of NNNS profiles in a multi-cohort study of preterm and term-born infants with different perinatal exposures.

METHODS

We studied 1112 infants with a neonatal NNNS exam from the Environmental influences on Child Health Outcomes (ECHO) consortium. We used latent profile analysis to characterize infant neurobehavioral profiles and generalized estimating equations to determine predictors of NNNS profiles.

RESULTS

Six distinct neonatal neurobehavioral profiles were identified, including two dysregulated profiles: a hypo-aroused profile (16%) characterized by lethargy, hypotonicity, and nonoptimal reflexes; and a hyper-aroused profile (6%) characterized by high arousal, excitability, and stress, with low regulation and poor movement quality. Infants in the hypo-aroused profile were more likely to be male, have younger mothers, and have mothers who were depressed prenatally. Infants in the hyper-aroused profile were more likely to be Hispanic/Latino and have mothers who were depressed or used tobacco prenatally.

CONCLUSIONS

We identified two dysregulated neurobehavioral profiles with distinct perinatal antecedents. Further understanding of their etiology could inform targeted interventions to promote positive developmental outcomes.

IMPACT

Prior research on predictors of neonatal neurobehavior have included single-cohort studies, which limits generalizability of findings. In a multi-cohort study of preterm and term-born infants, we found six distinct neonatal neurobehavioral profiles, with two profiles being identified as dysregulated. Hypo- and hyper-aroused neurobehavioral profiles had distinct perinatal antecedents. Understanding perinatal factors associated with dysregulated neurobehavior could help promote positive developmental outcomes.

NICU sensory experiences associated with positive outcomes: an integrative review of evidence from 2015-2020

To inform changes to the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, studies investigating sensory-based interventions in the NICU with preterm infants born ≤32 weeks were identified. Studies published between October 2015 to December 2020, and with outcomes related to infant development or parent well-being, were included in this integrative review. The systematic search used databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and Google Scholar. Fifty-seven articles (15 tactile, 9 auditory, 5 visual, 1 gustatory/olfactory, 5 kinesthetic, and 22 multimodal) were identified. The majority of the sensory interventions that were identified within the articles were reported in a previous integrative review (1995-2015) and already included in the SENSE program. New evidence has led to refinements of the SENSE program, notably the addition of position changes across postmenstrual age (PMA) and visual tracking starting at 34 weeks PMA.

All Care is Brain Care: Neuro-Focused Quality Improvement in the Neonatal Intensive Care Unit

Neonates requiring intensive care are in a critical period of brain development that coincides with the neonatal intensive care unit (NICU) hospitalization, placing these infants at high risk of brain injury and long-term neurodevelopmental impairment. Care in the NICU has the potential to be both harmful and protective to the developing brain. Neuro-focused quality improvement efforts address 3 main pillars of neuroprotective care: prevention of acquired injury, protection of normal maturation, and promotion of a positive environment. Despite challenges in measurement, many centers have shown success with consistent implementation of best and potentially better practices that may improve markers of brain health and neurodevelopment.

Supporting and Enhancing NICU Sensory Experiences (SENSE), 2nd Edition: An Update on Developmentally Appropriate Interventions for Preterm Infants

The Supporting and Enhancing NICU Sensory Experiences (SENSE) program promotes consistent, age-appropriate, responsive, and evidence-based positive sensory exposures for preterm infants each day of NICU hospitalization to optimize infant and parent outcomes. The initial development included an integrative review, stakeholder input (NICU parents and healthcare professionals), and feasibility focus groups. To keep the program updated and evidence-based, a review of the recent evidence and engagement with an advisory team will occur every 5 years to inform changes to the SENSE program. Prior to the launch of the 2nd edition of the SENSE program in 2022, information from a new integrative review of 57 articles, clinician feedback, and a survey identifying the barriers and facilitators to the SENSE program's implementation in a real-world context were combined to inform initial changes. Subsequently, 27 stakeholders (neonatologists, nurse practitioners, clinical nurse specialists, bedside nurses, occupational therapists, physical therapists, speech-language pathologists, and parents) carefully considered the suggested changes, and refinements were made until near consensus was achieved. While the 2nd edition is largely the same as the original SENSE program, the refinements include the following: more inclusive language, clarification on recommended minimum doses, adaptations to allow for variability in how hospitals achieve different levels of light, the addition of visual tracking in the visual domain, and the addition of position changes in the kinesthetic domain.

Benefits of maternally-administered infant massage for mothers of hospitalized preterm infants: a scoping review

OBJECTIVES

Infant massage (IM) is a well-studied, safe intervention known to benefit infants born preterm. Less is known about the benefits of maternally-administrated infant massage for mothers of preterm infants who often experience increased rates of anxiety and depression in their infants' first year of life. This scoping review summarizes the extent, nature, and type of evidence linking IM and parent-centered outcomes.

METHODS

The Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for scoping reviews (PRISMA-ScR) protocol was followed using three databases: PubMed, Embase, and CINAHL. Thirteen manuscripts evaluating 11 separate study cohorts met pre-specified inclusion criteria.

RESULTS

Six primary topics related to the influence of infant massage on parent outcomes emerged: 1) anxiety, 2) perceived stress, 3) depressive symptoms, 4) maternal-infant interaction, 5) maternal satisfaction, and 6) maternal competence. Emerging evidence supports that infant massage, when administered by mothers, benefits mothers of preterm infants by reducing anxiety, stress, and depressive symptoms and improving maternal-infant interactions in the short-term, but there is limited evidence to support its effectiveness on these outcomes in longer periods of follow-up. Based on effect size calculations in small study cohorts, maternally-administered IM may have a moderate to large effect size on maternal perceived stress and depressive symptoms.

CONCLUSIONS

Maternally-administered IM may benefit mothers of preterm infants by reducing anxiety, stress, depressive symptoms, and by improving maternal-infant interactions in the short-term. Additional research with larger cohorts and robust design is needed to understand the potential relationship between IM and parental outcomes.

A pivotal moment in the evolution of neonatal care

While extraordinary advances have been made in the medical care of critically ill newborns, understanding the need of even the smallest of these infants for early, extensive, intimate human contact and facilitating the family's role in the care of their baby has been much slower and inconsistent. There is abundant evidence for the essential role of nurturing parent-infant connections (bonding/attachment) for development of optimal physical, cognitive, and emotional health of all babies. It is time to leave behind the tradition of sensory deprivation and social isolation common in the care of high-risk infants. A paradigm shift is needed in neonatal care to acknowledge the critical importance of infant and family-centered developmental care and to remove any remaining constraints on a family's ability to become full partners in the nurture of their NICU newborn.

Feasibility of Implementing a Modified SENSE Program to Increase Positive Sensory Experiences for Preterm Infants in the Neonatal Intensive Care Unit (NICU): A Pilot Study

AIMS

To evaluate the feasibility of implementing the Supporting and Enhancing NICU Sensory Experiences (SENSE) program with adaptations to increase positive sensory exposure for infants born preterm, support neonatal neurodevelopment, and decrease parent stress.

METHODS

Eight infants born between 28 and 33 weeks were recruited within one week of birth. Parents, trained in the program, delivered the SENSE protocol. The first author provided up to 1 h of sensory input on weekdays when a parent could not be present.

RESULTS

Recruitment and retention rates were 87.5% and 100%, respectively. Recruitment and initial parent education and training averaged 37.5 min. On average, parents were present in the NICU 85.1% of days; they participated in SENSE for an average of 515.5 min. SENSE dose recommendations were not consistently met. Weekly infant assessments and regular parent check ins averaged 22.5 and 13.8 min, respectively. Post-assessments revealed normal scores on a neurodevelopmental assessment, low parent stress, and high parent satisfaction.

CONCLUSIONS

The recruitment and retention rates suggest high demand to participate. Outcomes for parent stress and neonatal neurodevelopment support continuation of SENSE. Time commitment for implementation, coupled with supporting families in meeting dose recommendations, suggest a need for a neonatal therapist to promote sustainability.

Neurobehavior in very preterm infants with low medical risk and full-term infants

OBJECTIVE

To describe differences in neurobehavior among very preterm infants with low medical risk at term equivalent age and full-term infants.

STUDY DESIGN

One-hundred eighty-six (136 infants born ≤32 weeks gestation with low medical risk at term equivalent age and 50 full-term infants within 4 days of birth) had standardized neurobehavioral assessments. Low medical risk was defined by ventilation <10 days and absence of significant brain injury, necrotizing enterocolitis, patent ductus arteriosus, and retinopathy of prematurity.

RESULTS

Very preterm infants with low medical risk at term equivalent age demonstrated more sub-optimal reflexes (p < 0.001; ß = 1.53) and more stress (p < 0.001; ß = 0.08) on the NICU Network Neurobehavioral Scale compared to their full-term counterparts. Very preterm infants with low medical risk also performed worse on the Hammersmith Neonatal Neurological Examination (p = 0.005; ß = -3.4).

CONCLUSION

Very preterm infants at term equivalent age continue to demonstrate less optimal neurobehavior compared to full-term infants.

Multisensory stimulation to promote feeding and psychomotor development in preterm infants: A systematic review

BACKGROUND

Sensory stimulation is an intervention that, through peripheral stimuli, can facilitate brain organization, due to neuronal plasticity and cortical reorganization. The objective of this study was to evaluate the evidence about the effects of a multisensory stimulation program, applied on preterm infants, compared to any intervention or standard care, to improve feeding behaviour, and psychomotor development.

METHODS

The data sources included Medline (pubmed, EBSCO), Scopus and Web Of Science. The studies were randomized clinical trials published between 2015 and 2021 that analyzed multisensory stimulation interventions in preterm infants born less than 37 weeks of pregnancy.

RESULTS

Nine articles were identified, involving 545 preterm infants between 25 and 37 weeks of pregnancy. The studies applied different combinations of sensory stimulation. These interventions were related to a better time to achieve full oral feeding and higher consumption of human milk at discharge, better psychomotor development and visual function. All studies scored 6 or higher on the PEDro scale meaning good quality.

CONCLUSION

Multisensory stimulation in preterm infants may improve feeding, psychomotor development, and visual function.

Parent-infant interaction in the NICU: Challenges in measurement

BACKGROUND

Parent-infant interaction is poorly understood among high-risk dyads in NICU settings. No parent-infant interaction measures are specifically designed for preterm infants within the NICU nor account for the education NICU parents receive to tailor their interactions based on the infant's cues.

AIM

To improve our understanding of a measure of parent-infant interaction in the NICU, we investigated relationships between parent-infant interaction scores on the Nursing Child Assessment Feeding Scale (NCAFS) and 1) socio-demographic and medical factors, 2) parent mental health and confidence, and 3) enhanced parental education (delivered as part of the Supporting and Enhancing NICU Sensory Experiences program) on tailoring interactions based on the infant's cues.

METHOD

Twenty-six preterm infants (born ≤32 weeks) had a video recorded oral feeding conducted by a parent in the NICU when the infant was 34-48 weeks postmenstrual age. A certified evaluator scored parent-infant interaction from the videos using the NCAFS.

RESULTS

Seventeen (65 %) parent-infant dyads scored below the 10th percentile on the total NCAFS score. Despite it being well-understood that parent-infant interaction is related to sociodemographic factors and parental mental health, there were no relationships between these factors and NCAFS scores in this study. Dyads who received enhanced parent education (n = 15) had lower NCAFS scores than dyads receiving usual care (n = 11) (p = 0.01).

CONCLUSION

It remains unclear if the standard measure of parent-infant interaction, NCAFS, captured positive and negative interactions in context of assessment of a high-risk dyad within the NICU setting. The utility of the NCAFS with preterm infants in the NICU was not supported by this study.

Early Postpartum Maternal and Newborn Responses to Auditory, Tactile, Visual, Vestibular, and Olfactory Stimuli

OBJECTIVE

To compare maternal psychological well-being, newborn behavior, and maternal and newborn salivary oxytocin (OT) and cortisol before and after two maternally administered multisensory behavioral interventions or an attention control group.

DESIGN

Randomized prospective clinical trial.

SETTING

U.S. Midwest community hospital.

PARTICIPANTS

Newborns and their mothers (n = 102 dyads) participated. Mothers gave birth vaginally at term gestation and had no physical or mental health diagnoses. Newborns with low Apgar scores, receipt of oxygen, suspected infection, or congenital anomalies were excluded.

METHODS

Dyads were randomly assigned to the auditory, tactile, visual, and vestibular (ATVV) intervention, the ATVV with odor from a baby lotion (ATVVO), or the attention control (AC) Group. Maternal psychological well-being, newborn behavior, and endocrine responses (salivary cortisol and OT) were measured before and after the intervention.

RESULTS

Newborns in the ATVV and ATVVO groups exhibited increases in potent engagement behaviors (p < .0001 and p = .001, respectively). Newborns in the AC group exhibited a decrease in potent engagement (p = .013) and an increase in potent disengagement (p = .029). Mothers in the ATVVO group exhibited an increase in OT (p = .01) and the largest change in OT (p = .02) compared to mothers in the ATVV and AC groups. We noted no change in maternal psychological well-being or newborn endocrine responses.

CONCLUSION

Inclusion of an odor via lotion with a behavioral intervention (ATVV) influenced maternal OT more than the behavioral intervention alone. Newborns were behaviorally responsive to the interventions; however, endocrine measures were not associated with intervention changes.

Health Care Professional Perceptions About a Proposed NICU Intervention: The Importance of Community and Aligning With Everyday Occupations

The neonatal intensive care unit (NICU) is a dynamic system with multiple stakeholders and contextual factors impacting the implementation of novel practices. This qualitative study aimed to (a) define health care professionals' perceptions on the feasibility of implementing a sensory intervention to study its efficacy, and (b) elaborate on transactions occurring between NICU health care professionals and the proposed research. Eleven NICU professionals participated in one of three focus groups that were audio-recorded, transcribed, and analyzed thematically in NVivo first descriptively and then interpretively through a transactionalism lens. The health care professionals implied the intervention was feasible, but provided multiple suggestions to enhance implementation. The modification of familiar occupational practices, ingrained habits, and the potential impact on the collective occupational performance of NICU community members arose. Understanding occupations within the NICU as transactional allows for a broader view of occupational engagement and enhances knowledge of the nuances related to implementing clinical changes.

Socio-demographic factors related to parent engagement in the NICU and the impact of the SENSE program

BACKGROUND

Early parent engagement in the neonatal intensive care unit (NICU) is important for both parent and infant mental health and for improving developmental outcomes. It remains unclear how different programs, such as the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, may empower parents from various socio-demographic groups to engage in the NICU. An improved understanding could aid in individualizing interventions for those at the highest risk for health disparities.

AIMS

This exploratory study, which was part of a larger study, sought to explore 1) socio-demographic factors related to parent presence and engagement in the NICU and 2) if the SENSE program related to increased parent presence and engagement among different socio-demographic groups.

METHODS

Seventy parent-infant dyads (born ≤ 32 weeks gestation) were randomized to SENSE programming (parent education and age-appropriate, positive sensory interventions for parents to conduct with their infants every day of hospitalization) or standard care after admission to the NICU. The amount of parent presence and participation in sensory activities was tracked using bedside logs, nursing records, and research team documentation.

RESULTS

Being married (p = 0.048; p = 0.01), having private insurance (p < 0.001; p = 0.01), and having fewer children (p = 0.004; p = 0.03) related to more parent presence and engagement respectively. Parents who were Black had less presence and engagement in the NICU (p = 0.04; p = 0.02). Participation in the SENSE program was related to more parent presence and engagement among younger mothers (p = 0.002; p ≤0.001) and among parents living farther distances from the hospital (p < 0.001; p = 0.004).

CONCLUSION

Programming, such as the SENSE program, can improve parent engagement in the NICU among high-risk groups.

A Survey of Neonatal Nurses Perspectives on Voice Use and Auditory Needs with Premature Infants in the NICU

BACKGROUND

Exposure to the voice and language during the critical period of auditory development associated with the third trimester is thought to be an essential building block for language. Differences in the auditory experience associated with early life in the NICU may increase the risk of language delays for premature infants. NICU nurses are fundamental in the care of premature infants; how they use their voices may be important in understanding auditory experiences in the NICU. This study examined voice use behaviors of NICU nurses in the United States and their current knowledge of early auditory development.

METHOD

An opt-in, online questionnaire.

RESULTS

Nurses reported using their voice more as the age of infants approached term gestation and speaking to infants was the most common type of voice use. Both infant and nurse factors influenced reported voice use decisions in the NICU. Nurses did not believe the NICU auditory environment to be sufficient to meet early auditory needs of premature infants but did believe that premature infants are exposed to adequate voice sounds.

CONCLUSIONS

A gap in knowledge regarding the importance of early exposure to voice sounds may be a barrier to nurses using their voices to support early auditory development.
