Implementing potentially better practices to support the neurodevelopment of infants in the NICU

Visual Acuity Thresholds in Preterm Newborns: An Experimental Study

Purpose: Visual acuity plays a role in mediating neurological development in infants by enabling the differentiation of shapes and discriminating objects. Given the rapid structural development of the brain in the first days of life, this aspect is particularly significant for preterm infants, who typically experience this developmental phase while hospitalized in the neonatal intensive care unit (NICU). Therefore, this study aimed to assess visual acuity thresholds in preterm infants during hospitalization and to evaluate possible correlations between visual acuity and clinical parameters. Methods: A cross-sectional study was conducted in an NICU in Northeast Brazil. The visual acuity thresholds were tested using the Teller Acuity Cards II, comprised of 17 gray cards, with one 4 mm diameter peephole at the center and presented with about 35% reflectance. Preterm infants were positioned supine, at 30° elevation on the laps of their caregivers. The evaluator presented both sides of the cards and observed the eye fixation and reactions on both sides. Results: A total of 42 preterm infants with corrected gestational age between 30 to 36 weeks and 6 days were included. Visual acuity ranged from 0.23 to 0.64 cycle per degree. The mean visual acuity threshold was 0.32 cycles per degree for preterm infants at around 32 weeks of corrected gestational age. The visual acuity was not correlated with gestational age (p = 0.18), and neither were birth weight (p = 0.83) or duration of respiratory support (p = 0.98). However, days of phototherapy were inversely correlated with visual acuity (p = 0.04). Conclusions: Despite the challenges of hospitalization, it was possible to carry out a psychophysical test to assess visual acuity in preterm infants. The visual acuity showed no correlation with clinical parameters such as gestational age, birth weight, and duration of respiratory support. However, there was an inverse correlation between the number of days in phototherapy and visual acuity. Understanding the visual acuity levels in preterm infants during their NICU stay can contribute to tailoring interventions and care strategies that specifically address their visual developmental needs. This knowledge may guide healthcare professionals in optimizing the NICU environment to provide appropriate visual stimuli that support neurological development.

Defining the Concept of Acoustic Neuroprotection in the Neonate: A Concept Analysis

BACKGROUND

It has long been understood and acknowledged that the Neonatal Intensive Care Unit (NICU) environment and the transport environments are extremely loud, with both long- and short-term sequelae to the neonate, being well over the recommended amount of noise by the American Academy of Pediatrics (AAP). This problem has yet to be properly addressed. The purpose of this manuscript is to define and explain the concept of acoustic neuroprotection. While we cannot change the internal structures of the neonates' auditory system, we could change the acoustics of the environment to be support neuroprotection of these sensitive patients.

EVIDENCE ACQUISITION

Walker and Avant's concept analysis steps were followed to create and define the idea of acoustic neuroprotection, as it has not had a definition before. A total of 45 articles from multiple search engines were chosen. A combination of 2 concepts were used: acoustic protection and neurodevelopmental protection/support. The search was expanded past 20 years for lack of research and importance of seminal works.

RESULTS

To achieve acoustic neuroprotection, a neonate should not be exposed to sound greater than 45 decibels (dBa) for longer than 10 s, and exposure to sound above 80 dBa should never occur. Appropriate interventions need to include supporting the neurodevelopment of the neonate through therapeutic sound, while decreasing the amount of toxic noise exposure to safe levels.

IMPLICATIONS FOR PRACTICE AND RESEARCH

By further understanding and having a quantifiable goal of acoustic neuroprotection for neonates, neonatal clinicians can work together to create new interventions for how to better protect and support the care of our tiniest patients.

Sleep state organisation of moderate to late preterm infants in the neonatal unit

BACKGROUND

Sleep supports neurodevelopment and sleep architecture reflects brain maturation. This prospective observational study describes the nocturnal sleep architecture of healthy moderate to late preterm (MLP) infants in the neonatal unit at 36 weeks post menstrual age (PMA).

METHODS

MLP infants, in the neonatal unit of a tertiary hospital in Ireland from 2017 to 2018, had overnight continuous electroencephalography (cEEG) with video for a minimum 12 h at 36 weeks PMA. The total sleep time (TST) including periods of active sleep (AS), quiet sleep (QS), indeterminate sleep (IS), wakefulness and feeding were identified, annotated and quantified.

RESULTS

A total of 98 infants had cEEG with video monitoring suitable for analysis. The median (IQR) of TST in the 12 h period was 7.09 h (IQR 6.61-7.76 h), 4.58 h (3.69-5.09 h) in AS, 2.02 h (1.76-2.36 h) in QS and 0.65 h (0.48-0.89 h) in IS. The total duration of AS was significantly lower in infants born at lower GA (p = 0.007) whilst the duration of individual QS periods was significantly higher (p = 0.001).

CONCLUSION

Overnight cEEG with video at 36 weeks PMA showed that sleep state architecture is dependent on birth GA. Infants with a lower birth GA have less AS and more QS that may have implications for later neurodevelopment.

IMPACT

EEG provides objective information about the sleep organisation of the moderate to late preterm (MLP) infant. Quantitative changes in sleep states occur with each week of advancing gestational age (GA). Active sleep (AS) is the dominant sleep state that was significantly lower in infants born at lower GA. MLP infants who were exclusively fed orally had a shorter total sleep time and less AS compared to infants who were fed via nasogastric tube.

Using complexity science to understand the role of co-sleeping (bedsharing) in mother-infant co-regulatory processes

Human infants spend most of their time sleeping, but over the first few years of life their sleep becomes regulated to coincide more closely with adult sleep (Galland et al., 2012; Paavonen et al., 2020). Evidence shows that co-sleeping played a role in the evolution of infant sleep regulation, as it is part of an ancient behavioral complex representing the biopsychosocial microenvironment in which human infants co-evolved with their mothers through millions of years of human history (Ball, 2003; McKenna 1986, 1990). This paper is a conceptual, interdisciplinary, integration of the literature on mother-infant co-sleeping and other mother-infant co-regulatory processes from an evolutionary (biological) perspective, using complexity science. Viewing the mother-infant dyad as a "complex adaptive system" (CAS) shows how the CAS fits assumptions of regulatory processes and reveals the role of the CAS in the ontogeny of mother-infant co-regulation of physiological (thermoregulation, breathing, circadian rhythm coordination, nighttime synchrony, and heart rate variability) and socioemotional (attachment and cortisol activity) development.

CUIDADOS CENTRADOS NO DESENVOLVIMENTO DO RECÉM-NASCIDO PREMATURO: ESTUDO SOBRE AS PRÁTICAS EM UNIDADES NEONATAIS PORTUGUESAS

RESUMO Objetivo: analisar a frequência da aplicação das medidas centrais dos cuidados desenvolvimentais ao recém-nascido prematuro em unidades de cuidados neonatais portuguesas e identificar a sua relação com variáveis organizacionais. Método: estudo transversal, descritivo-correlacional. Utilizando técnica de amostragem não probabilística em rede, foi obtida uma amostra de 217 enfermeiros de unidades neonatais portuguesas que responderam online ao questionário Quantum Caring Practice Self-Assessment, traduzido e validado para enfermeiros portugueses. Resultados: os resultados revelaram que para 65,4% dos enfermeiros as práticas de cuidados centrados no desenvolvimento são realizadas às vezes e 14,3% consideram que raramente são realizadas. Somente 18,9% dos enfermeiros inquiridos consideram que essas práticas são realizadas frequentemente. Destacaram-se como práticas mais frequentes, as ligadas ao Ambiente terapêutico e Prevenção da dor e stress. As menos frequentes foram as medidas de Posicionamento e Cuidados à pele. Os resultados demonstraram ainda que a frequência das práticas de cuidados desenvolvimentais difere consoante a localização geográfica das unidades e é mais elevada nas unidades com maior nível de diferenciação de cuidados e que têm instituído um programa/protocolo específico de cuidados desenvolvimentais. Conclusão: as práticas de cuidados centrados no desenvolvimento não são realizadas de forma consistente nas unidades de cuidados neonatais portuguesas, apesar de serem exequíveis. É necessária uma mudança global na cultura das equipas, mais formação, implementação de protocolos e investimento organizacional nesta área.

DEVELOPMENTAL CARE OF PREMATURE NEWBORNS: STUDY ON PRACTICES IN PORTUGUESE NEONATAL UNITS

ABSTRACT Objective: the present and future well-being of hospitalized newborns and their parents are connected to analyze the application frequency of the central practices of developmental care to premature newborns in Portuguese neonatal care units and to identify their relationship with organizational variables. Method: cross-sectional, descriptive-correlational study. Using a non-probabilistic network sampling technique, a sample of 217 nurses from Portuguese neonatal units who answered the Quantum Caring Practice Self-Assessment online questionnaire was obtained, previously translated and validated for Portuguese nurses. Results: the results revealed that for 65.4% of nurses, Developmental Care practices are sometimes performed and 14.3% consider that they are rarely performed. Only 18.9% of the nurses in the study consider that these practices are performed frequently. The most frequent practices were those related to the therapeutic environment and prevention of pain and stress. The least frequent was positioning and skin care. The results also showed that the frequency of developmental care practices differs depending on the geographical location of the units and is higher in units with a higher level of treatment differentiation and that have established a specific program/protocol of developmental care. Conclusion: although feasible, Developmental Care practices are not performed consistently in Portuguese neonatal care units. A global change in team culture, more training, implementation of protocols and organizational investment in this area is needed.

The Soundscape of Neonatal Intensive Care: A Mixed-Methods Study of the Parents' Experience

Parents who have infants hospitalised in neonatal intensive care units (NICUs) experience high levels of stress, including post-traumatic stress disorder (PTSD) symptoms. However, whether sounds contribute to parents’ stress remains largely unknown. Critically, researchers lack a comprehensive instrument to investigate the relationship between sounds in NICUs and parental stress. To address this gap, this report presents the “Soundscape of NICU Questionnaire” (SON-Q), which was developed specifically to capture parents’ perceptions and beliefs about the impact that sound had on them and their infants, from pre-birth throughout the NICU stay and in the first postdischarge period. Parents of children born preterm (n = 386) completed the SON-Q and the Perinatal PTSD Questionnaire (PPQ). Principal Component Analysis identifying underlying dimensions comprising the parental experience of the NICU soundscape was followed by an exploration of the relationships between subscales of the SON-Q and the PPQ. Moderation analysis was carried out to further elucidate relationships between variables. Finally, thematic analysis was employed to analyse one memory of sounds in NICU open question. The results highlight systematic associations between aspects of the NICU soundscape and parental stress/trauma. The findings underscore the importance of developing specific studies in this area and devising interventions to best support parents’ mental health, which could in turn support infants’ developmental outcomes.

Transition to a Safe Home Sleep Environment for the NICU Patient

Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (<2500 g [5.5 lb]) and 10% were born preterm (gestational age of <37 completed weeks). Many of these infants and others with congenital anomalies, perinatally acquired infections, and other disease require admission to a NICU. In the past decade, admission rates to NICUs have been increasing; it is estimated that between 10% and 15% of infants will spend time in a NICU, representing approximately 500 000 neonates annually. Approximately 3600 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome International Classification of Diseases, 10th Revision (R95), ill-defined deaths (R99), and accidental suffocation and strangulation in bed (W75). Preterm and low birth weight infants are particularly vulnerable, with an incidence of death 2 to 3 times greater than healthy term infants. Thus, it is important for health care professionals to prepare families to maintain their infant in a safe sleep environment, as per the recommendations of the American Academy of Pediatrics. However, infants in the NICU setting commonly require care that is inconsistent with infant sleep safety recommendations. The conflicting needs of the NICU infant with the necessity to provide a safe sleep environment before hospital discharge can create confusion for providers and distress for families. This technical report is intended to assist in the establishment of appropriate NICU protocols to achieve a consistent approach to transitioning NICU infants to a safe sleep environment as soon as medically possible, well before hospital discharge.

Efficacy of noise reduction bundle in reducing sound levels in a Level II neonatal care unit in China

BACKGROUND

Noise is a hazard for newborns. Preterm infants are more vulnerable to negative effects of noise because their auditory system is at a critical period of neurodevelopment. We conducted this study to determine whether noise exposure in our Level II unit met the American Academy of Pediatrics (AAP)-issued recommendation of less than 45 dB. We also aimed to assess the efficacy of a bundle of noise reduction methods and the role of noise supervisors in assuring the compliance of modification.

METHODS

Hourly mean equivalent continuous noise level (Leq) was collected in two phases: (I) Phase 1: baseline data for 4 weeks, (II) Phase 2: study period for 13 weeks, 1 week (Stage 1) under close monitoring by the noise supervisors and 12 weeks (Stages 2, 3 and 4, lasting 4 weeks each) without supervisors.

RESULTS

The baseline noise level consistently exceeded recommendations with an hourly mean incubator noise of 53.6 dB (±5.2). Our bundle resulted in a significant reduction in incubator noise levels by 9.1 dB (±0.75). The sound levels remained <45 dB most of the time except for three-time windows, correlating with morning handovers/physical assessments (7:00-9:00), procedures/discharges/phone calls (13:00-15:00), and night handovers (19:00-20:00). The change in the reduction was most significant (-4.1 dB) in Stage 1 during the day shift. A minor trend of decline in sound levels inside the incubator was observed from Stage 1 to Stage 2 (P=0.057), with a rebound occurring in Stage 3 followed by stabilization in Stage 4, suggesting the role of noise supervisors in ensuring the compliance of the modification.

CONCLUSIONS

The baseline noise levels consistently exceeded recommendations, but the bundle was effective in achieving the reduction. Noise supervisors are essential to ensure the compliance of the modification. Resolution focused on the three-time windows is required in future work.

Tracheostomy in Infants in the Neonatal Intensive Care Unit

Approximately half of all pediatric tracheostomies are performed in infants younger than 1 year. Most tracheostomies in patients in the NICU are performed in cases of chronic respiratory failure requiring prolonged mechanical ventilation or upper airway obstruction. With improvements in ventilation and management of long-term intubation, indications for tracheostomy and perioperative management in this population continue to evolve. Evidence-based protocols to guide routine postoperative care, prevent and manage tracheostomy emergencies including accidental decannulation and tube obstruction, and attempt elective decannulation are sparse. Clinician awareness of safe tracheostomy practices and larger, prospective studies in infants are needed to improve clinical care of this vulnerable population.

Guidelines for the Institutional Implementation of Developmental Neuroprotective Care in the Neonatal Intensive Care Unit. Part A: Background and Rationale. A Joint Position Statement From the CANN, CAPWHN, NANN, and COINN

The use of age-appropriate care as an organized framework for care delivery in the neonatal intensive care unit is founded on the work of Heidelise Als, PhD, and her synactive theory of development. This theoretical construct has recently been advanced by the work of Gibbins and colleagues with the "universe of developmental care" conceptual model and developmental care core measures which were endorsed by the National Association of Neonatal Nurses in their age-appropriate care of premature infant guidelines as best-practice standards for the provision of high-quality care in the neonatal intensive care unit. These guidelines were recently revised and expanded. In alignment with the Joint Commission's requirement for health-care professionals to provide age-specific care across the lifespan, the core measures for developmental care suggest the necessary competencies for those caring for the premature and critically ill hospitalized infant. Further supported by the Primer Standards of Accreditation and Health Canada, the institutional implementation of theses core measures requires a strong framework for institutional operationalization, presented in these guidelines. Part A of this article will present the background and rationale behind the present guidelines and their condensed table of recommendations.

Improving Neurodevelopmental Outcomes in NICU Patients

BACKGROUND

Premature infants experience stressors such as external stimulation with sounds, light, touch, and open positioning in NICU that negatively affect outcomes.

PURPOSE

The purpose of this study was to measure the effectiveness of a developmental positioning intervention on length of stay, weight gain, and tone/flexion compared with neonates without structured positioning.

METHODS

Study design was quasi-experimental with nonequivalent groups. A retrospective chart review of 50 neonates with the inclusion criteria of 34 weeks of gestation or less and no anomalies provided a preintervention sample. After the education in-service on positioning, a convenience sample of 27 infants was enrolled. Infant Position Assessment Tool was used as a visual guide for positioning and scoring by the researcher for intervention fidelity. Hammersmith scoring was completed by the occupational therapist prior to discharge.

FINDINGS

The postintervention group was younger and sicker than the control group (P < .05). The postintervention sample (M = 7.05 where 7 = 29 to <30 weeks of gestation) was younger than the preintervention sample (M = 7.22). The postintervention sample was smaller (M = 1302.15 g) than the preintervention sample (M = 1385.94 g). Results showed that the postintervention group had clinically significant weight gain and mean Hammersmith score (3.28) was higher showing positioning positively affected tone and flexion scores.

IMPLICATIONS FOR PRACTICE

With greater structure and consistent attention to developmental positioning, outcomes are positively affected.

IMPLICATIONS FOR FUTURE RESEARCH

Further research with larger sample sizes will identify stronger associations and relationships between positioning and outcome measures.

Experience of neonatal intensive care unit nurses in providing developmentally-supportive care: A qualitative study

Many challenges have been noted in the implementation of developmentally-supportive care principles in neonatal intensive care units, despite evidence that adhering to such care principles achieves positive results for the neonate. The aim of this study was to explore and describe compliance in adhering to developmentally-supportive care principles implemented in one neonatal intensive care unit in South Africa. An exploratory design was used in this qualitative study with purposive sampling to select eligible neonatal intensive care registered nurses (n = 14) as participants. Participants all worked in a 10 bed neonatal intensive care unit at a large tertiary care public hospital. Six audio-recorded interviews were conducted, with recordings subsequently transcribed and analyzed. Three main themes were identified: value of developmentally-supportive care, nature of developmentally-supportive care, and barriers to developmentally-supportive care. One of the main themes had subthemes, which substantiated the findings, and included parent involvement, nurse engagement, and holistic care. Study outcomes offer insight into the development or revision of policies and practices, which are crucial when implementing developmentally-supportive care, particularly in resource-poor settings where challenges are magnified.

Nurses' and Physicians' Experiences of the NIDCAP Model Implementation in Neonatal Intensive Care Units in Iran

PURPOSE

The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) provides comprehensive newborn focused family-centered care in the Neonatal Intensive Care Unit (NICU). The purpose of this study was to investigate nurses' and physicians' experiences of implementing the NIDCAP model to optimize its implementation for both caregivers, infants, and families in the NICU.

DESIGN & METHODS

A purposes sample of 11 nurses and four physicians participated in this qualitative study. Data were collected by face-to-face and semi-structured interviews and analysis were guided by principles of thematic analysis as per Graneheim and Lundman (2004).

RESULTS

Six themes and 20 sub-themes were constructed during data analysis. These included; NIDCAP as a milestone, Helping to rebuild the core of the family, Caregiver excellence, Realism towards the feasibility of NIDCAP, Proper managerial position of NIDCAP specialists in the health system, and Caring for the caregiver.

CONCLUSIONS

The findings of this study highlight how NIDCAP provides a comprehensive and effective care model for premature infants, with the goal to promote neonatal growth and development while also facilitating the self-efficacy of caregivers. Implementation of the NIDCAP model requires attention to be paid to social context, infrastructure, adjustment of the program according to the facilities and resources of each country, and the needs of caregivers.

PRACTICE IMPLICATIONS

Health care resources are required to sustain NIDCAP specialists and a favorable environment as the necessary conditions for its multidimensional application across NICU units around the world.

The human newborn's umwelt: Unexplored pathways and perspectives

Historically, newborns, and especially premature newborns, were thought to "feel nothing." However, over the past decades, a growing body of evidence has shown that newborns are aware of their environment, but the extent and the onset of some sensory capacities remain largely unknown. The goal of this review is to update our current knowledge concerning newborns' perceptual world and how ready they are to cope with an entirely different sensory environment following birth. We aim to establish not only how and when each sensory ability arises during the pre-/postbirth period but also discuss how senses are studied. We conclude that although many studies converge to show that newborns are clearly sentient beings, much is still unknown. Further, we identify a series of internal and external factors that could explain discrepancies between studies, and we propose perspectives for future studies. Finally, through examples from animal studies, we illustrate the importance of this detailed knowledge to pursue the enhancement of newborns' daily living conditions. Indeed, this is a prerequisite for assessing the effects of the physical environment and routine procedures on newborns' welfare.

Survey of preterm neuro-centric care practices in California neonatal intensive care units

OBJECTIVE

Examine the adoption and presence of preterm, neuro-centric care practices across neonatal intensive care units (NICUs).

STUDY DESIGN

Statewide, cross-sectional survey of California NICUs. Data were collected surrounding the timing of adoption and presence of delivery room practices, nursing protocols, provider management practices and quality improvement initiatives.

RESULT

Among the 95 NICUs completing the survey (65%), adoption of all surveyed practices increased between 2005 and 2016, though rates of uptake changed over time and varied by practice. Adoption of indomethacin prophylaxis increased 1.8-fold, whereas delayed cord clamping increased 78-fold. Adoption of premedication for intubation and a patent ductus arteriosus management algorithm differed by unit level. Additionally, two underlying practice domains were identified; adoption of delivery room practices and adoption of any preterm practice.

CONCLUSION

Adoption of preterm, neuro-centric care practices across California NICUs has increased, though uptake patterns vary by practice and level.

Noise in the neonatal intensive care unit: a new approach to examining acoustic events

INTRODUCTION

Environmental noise is associated with negative developmental outcomes for infants treated in the neonatal intensive care unit (NICU). The existing noise level recommendations are outdated, with current studies showing that these standards are universally unattainable in the modern NICU environment.

STUDY AIM

This study sought to identify the types, rate, and levels of acoustic events that occur in the NICU and their potential effects on infant physiologic state.

MATERIALS AND METHODS

Dosimeters were used to record the acoustic environment in open and private room settings of a large hospital NICU. Heart and respiratory rate data of three infants located near the dosimeters were obtained. Infant physiologic data measured at time points when there was a marked increase in sound levels were compared to data measured at time points when the acoustic levels were steady.

RESULTS

All recorded sound levels exceeded the recommended noise level of 45 decibels, A-weighted (dBA). The 4-h Leq of the open-pod environment was 58.1 dBA, while the private room was 54.7 dBA. The average level of acoustic events was 11-14 dB higher than the background noise. The occurrence of transient events was 600% greater in the open room when compared to the private room. While correlations between acoustic events and infant physiologic state could not be established due to the extreme variability of infant state, a few trends were visible. Increasing the number of data points to overcome the extreme physiologic variability of medically fragile neonates would not be feasible or cost-effective in this environment.

CONCLUSION

NICU noise level recommendations need to be modified with an emphasis placed on reducing acoustic events that disrupt infant state. The goal of all future standards should be to optimize infant neurodevelopmental outcomes.

Unobtrusive assessment of neonatal sleep state based on heart rate variability retrieved from electrocardiography used for regular patient monitoring

As an approach of unobtrusive assessment of neonatal sleep state we aimed at an automated sleep state coding based only on heart rate variability obtained from electrocardiography used for regular patient monitoring. We analyzed active and quiet sleep states of preterm infants between 30 and 37weeks postmenstrual age. To determine the sleep states we used a nonlinear kernel support vector machine for sleep state separation based on known heart rate variability features. We used unweighted and weighted misclassification penalties for the imbalanced distribution between sleep states. The validation was performed with leave-one-out-cross-validation based on the annotations of three independent observers. We analyzed the classifier performance with receiver operating curves leading to a maximum mean value for the area under the curve of 0.87. Using this sleep state separation methods, we show that automated active and quiet sleep state separation based on heart rate variability in preterm infants is feasible.

The NICU Environment: Infusing Single-Family Room Benefits into the Open-Bay Setting

Two distinct architectural designs are found in today's NICUs-the open-bay (OPBY) and the single-family room (SFR) designs. When neonatology was recognized as a medical subspecialty in the 1970s, the OPBY design was the only platform offered to neonates and families. The OPBY design facilitated communication between staff, collegiality, and interprofessional collaboration among members of the neonatal team. Over time, pitfalls to the design were recognized, including increased transmission of sound and light. As a result, the SFR design emerged offering a family-centered, customizable environment. Through recognition and adoption of best practices, the neurodevelopmental benefits to SFRs can be infused within the OPBY unit. This article aims to identify best practices to infuse the benefits of SFR design (such as low light, low sound, and less overstimulation) into the OPBY NICU to reduce negative stimulation and optimize developmental outcomes for vulnerable neonates.

The Impact of a Neonatal Sleep Care Training Program on Nurses' Knowledge and Performance in Neonatal Intensive Care Units

BACKGROUND

Sleep is essential for organizing and maturation of the brain in premature infants; it also plays a role in maintaining the natural balance between different nervous centers. Given the role of nurses in neonatal sleep care, this study aimed at assessing the impact of a training program on the nurses' knowledge and performance in a Neonatal Intensive Care Unit (NICU).

MATERIALS AND METHODS

In this quasi-experimental study which structured into three stages, 35 nurses working in an NICU in Isfahan, Iran, were included. The neonatal sleep training program was in the form of a lecture with questions and answers and then placing posters and booklets in the NICU. The data were collected by a questionnaire for nurses' knowledge and performance assessment which its validity and reliability were determined through content validity and internal consistency, respectively. The nurses' knowledge was assessed via 40 multiple-choice questions before, immediately after, and 1 month after the training program, and their performance was evaluated before and 1 month after intervention using 15 multiple-choice questions. The data were analyzed by descriptive and inferential statistics using the SPSS software version 16.

RESULTS

The results showed that the mean score of nurses' knowledge after training has significantly increased as compared to before training (33.33 (4.4) vs. 19.33 (4.1)) (P < 0.001); however, the score of performance was slightly improved although it did not reveal any significant differences (P = 0.07, 42.6 (7.6) vs. 45.1 (7.8)).

CONCLUSIONS

The results indicated that this method of training program could lead to an increase in nurses' knowledge, but it did not significantly improve their performance. It may be due to a low number of training sessions; therefore, it is recommended to implement long-term training programs in this field.

[Development of the Developmental Support Competency Scale for Nurses Caring for Preterm Infants]

PURPOSE

Developmental care has been recognized as a very important component for the development and health promotion of preterm infants. However, research on how to assess developmental nursing competency has not been studied as expected. This study was done to develop and evaluate a new scale to measure nursing competency for developmental support of preterm infants.

METHODS

Concept analysis was done with using the Hybrid model of Schwartz-Barcott and Kim (2000), from which a preliminary new scale (30 items) was developed. To test the validity and reliability of the new scale being developed, data were collected from 122 NICU nurses at 4 hospitals in 3 cities in the Republic of Korea, from December, 2014 to March, 2015.

RESULTS

The final version of the Developmental Support Competency Scale for Nurses (DSCS-N) caring for premature infants was a 4-point Likert type scale, consisting of 19 items, and categorized as 6 factors, explaining 62.5% of the total variance. Each of the factors were named as follows; 'environmental support' (4 items), 'parental support' (3 items), 'interaction' (3 items), 'critical thinking' (3 items), 'professional development' (3 items), and 'partnership' (3 items). The Cronbach's α coefficient for the scale was .83 and the reliability of the subscales ranged from .60~.76.

CONCLUSION

The psychometric evaluation of the new scale demonstrated an acceptable validity and reliability. Findings indicate that the DSCS-N can be used as the tool to test the effect of educational programs for nurses and contribute to advance developmental care for preterm infants.

Contextual factors influencing the implementation of the obstetrics hemorrhage initiative in Florida

OBJECTIVE

The purpose of this study was to explore the multilevel contextual factors that influenced the implementation of the Obstetric Hemorrhage Initiative (OHI) among hospitals in Florida.

STUDY DESIGN

A qualitative evaluation was conducted via in-depth interviews with multidisciplinary hospital staff (n=50) across 12 hospitals. Interviews were guided by the Consolidated Framework for Implementation Research and analyzed in Atlas.ti using rigorous qualitative analysis procedures.

RESULT

Factors influencing OHI implementation were present across process (leadership engagement; engaging people; planning; reflecting), inner setting (for example, knowledge/beliefs; resources; communication; culture) and outer setting (for example, cosmopolitanism) levels. Moreover, factors interacted across levels and were not mutually exclusive. Leadership and staff buy-in emerged as important components influencing OHI implementation across disciplines.

CONCLUSION

Key contextual factors found to influence OHI implementation experiences can be useful in informing future quality improvement interventions given the institutional and provider-level behavioral changes needed to account for evolving the best practices in perinatology.

Effect of peer education on the noise management in Iranian neonatal intensive care unit

Background:

Advancements in neonatal intensive care unit (NICU) science and technology have increased the survival rate of preterm infants. Despite these advances, they are still facing with neurobehavioral problems. Noise level in NICU is a potential source of stress for preterm infants. It should be decreased to the standard level as much as possible. The purpose of this study was to evaluate the effect of peer education on the performance of staff in noise management in the NICU.

Materials and Methods:

A pre-post test quasi-experimental design was used. Fifty-eight staff members (nurses and physicians) participated in this study. Sound pressure levels were measured before and after the intervention. Peer education program formed the intervention. The staff performance in noise management was evaluated before and after the intervention by using a questionnaire. Data analysis was done by using t-test.

Results:

The results of the study showed that the mean sound level in different environments significantly decreased after the intervention. It reached from 86.7 to 74.9 dB in the center of unit and from 68.2 to 48.50 dB in the infants' bedside (P < 0.0001). The mean score of the staff performance in noise management significantly increased after the intervention, compared to the pre-intervention score. It increased from 74.6 to 83.4 (P < 0.0001).

Conclusions:

Peer education was found to be successful in noise management because behavioral changes were done to avoid generating unnecessary noise by the staff.

Nurses' Awareness of Preterm Neonates' Sleep in the NICU

Introduction:

Fetus and neonate spend most of their time sleeping inside and outside the womb. Sleep is considered a crucial action of neonatal period similar to breathing and nutrition. It plays a key role in brain development. Today, it is shown that sleep plays a predominant role in body temperature regulation, energy saving and neuronal detoxification. Sleep is the most important behavioral state of neonates, particularly in preterm ones. Noise, light, invasive treatment and caring activities are among disturbing factors in the neonatal intensive care unit (NICU) that leave negative impacts on brain development through disturbing the sleep process.

Materials and Methods:

This descriptive study assessed all NICU nurses of Ali-ibn-Abitaleb hospital using the census sampling method. Demographic data was collected through a questionnaire with 10 questions about active sleep (AS) cycles, also referred to as REM, methods for inducing AS and AS specifications in neonates. The questionnaire was distributed between the nurses. After completion, data was analyzed using SPSS 16 and descriptive statistics method.

Findings:

According to analyses, 24%, 20%, 48% and 92% of nurses gave correct answers to questions about AS cycle, AS in neonates, the role of sleep in saving energy and ideal noise level, respectively.

Conclusion:

According to results, nurses had a low level of knowledge towards neonatal sleep. All nurses need to know the importance of sleep in preterm neonates. The main role of inducing sleep is to protect the development of the neonates’ brain in the NICU. Those nurses who spend a remarkable portion of their time for caring neonates in the NICU play a significant role in neonatal sleep care.

Impact of the NICU environment on language deprivation in preterm infants

It is unclear whether the atypical language development commonly seen in preterm infants is a consequence of language deficiency experienced during their prolonged NICU stay. This review provides a novel viewpoint, which highlights the potential impact of the NICU design on the developmental origin of language disabilities in preterm infants.

CONCLUSION

Further research is needed to identify evidence-based design solutions for providing preterm infants with a healthier linguistic hospital environment that aids growth and development.

Quality improvement initiatives in neonatal intensive care unit networks: achievements and challenges

Neonatal intensive care unit networks that encompass regions, states, and even entire countries offer the perfect platform for implementing continuous quality improvement initiatives to advance the health care provided to vulnerable neonates. Through cycles of identification and implementation of best available evidence, benchmarking, and feedback of outcomes, combined with mutual collaborative learning through a network of providers, the performance of health care systems and neonatal outcomes can be improved. We use examples of successful neonatal networks from across North America to explore continuous quality improvement in the neonatal intensive care unit, including the rationale for the formation of neonatal networks, the role of networks in continuous quality improvement, quality improvement methods and outcomes, and barriers to and facilitators of quality improvement.

Neonatal nursery noise: practice-based learning and improvement

OBJECTIVES

To study the impact of interrupted loud noise in Neonatal Intensive Care Unit (NICU) on neonatal physiologic parameters, and apply methods to alleviate noise sources through teaching NICU's staff.

METHODS

Noise level measured at different day times and during different noisy events in the NICU. Changes in the heart rate, respiratory rate and oxygen saturation were recorded just before and immediately after providing noisy events for 36 preterm and 26 full-term neonates. Focused training, guided by sound-level-meter, was provided to the NICU's staff to minimize noise.

RESULTS

The highest mean baseline noise level, 60.5 decibel (dB), was recorded in the NICU critical care area at 12:00 am. The lowest level, 55.2 dB was recorded at 10:00 pm. Noise level inside the incubators was significantly lower than outside, p < 0.001. Noisy events resulted in a significant increase in heart and respiratory rates in preterm neonates as compared to full-terms, p < 0.05.

CONCLUSION

Noise in our NICU exceeded the international permissible levels. Noisy events are numerous, which altered the neonates' physiologic stability especially preterm infants. Staff education is mandatory in ameliorating noise pollution with its deleterious effects on neonatal physiologic homeostasis.

Auditory brain development in premature infants: the importance of early experience

Preterm infants in the neonatal intensive care unit (NICU) often close their eyes in response to bright lights, but they cannot close their ears in response to loud sounds. The sudden transition from the womb to the overly noisy world of the NICU increases the vulnerability of these high-risk newborns. There is a growing concern that the excess noise typically experienced by NICU infants disrupts their growth and development, putting them at risk for hearing, language, and cognitive disabilities. Preterm neonates are especially sensitive to noise because their auditory system is at a critical period of neurodevelopment, and they are no longer shielded by maternal tissue. This paper discusses the developmental milestones of the auditory system and suggests ways to enhance the quality control and type of sounds delivered to NICU infants. We argue that positive auditory experience is essential for early brain maturation and may be a contributing factor for healthy neurodevelopment. Further research is needed to optimize the hospital environment for preterm newborns and to increase their potential to develop into healthy children.

Safe sound exposure in the fetus and preterm infant

Exposure to sound can have beneficial and harmful effects on the developing fetus and preterm infant. Although recommendations for safe exposure to sound have existed for more than three decades, reports indicate that these recommendations are not being followed. Recommendations are made to promote attention to the problem of unsafe exposure to sound in early development, and a multidisciplinary team, including representatives from disciplines beyond medicine and nursing, must redress safe exposure.

The gustatory and olfactory systems during infancy: implications for development of feeding behaviors in the high-risk neonate

This article reviews the development of the senses of taste and smell, which provide information on the flavor of foods, and discusses how innate predispositions interact with early-life feeding experiences to form children's dietary preferences and habits. A basic understanding of the development and functioning of the chemical senses during early childhood may assist in forming evidence-based strategies to improve children's diets, especially for those who experience a discontinuity or disruption in early flavor experiences.

Exploring the olfactory environment of premature newborns: a French survey of health care and cleaning products used in neonatal units

AIM

To assess the main determinants of the newborn's nosocomial olfactory environment.

METHODS

An electronic questionnaire was sent to 99 neonatal units in France. Senior nurses and/or physicians described the nature and use of skin care products (e.g. umbilical cord and skin disinfectants, adhesive removers), lubrications used for tubes positioning, disinfectants used to clean materials, hand hygiene products (e.g. alcohol-based hand rubs, soaps) and newborns' bath.

RESULTS

Nine groups of products and 76 distinct commercial preparations were identified. Depending on their level of respiratory support, preterm newborns were estimated to be exposed to nosocomial odours (NO) an average of 1320-1800 times during their first month of life. During their whole hospital stay, newborns of 28 and 32 weeks of gestational age could be exposed to NOs products an average of 3448 and 2024 times, respectively. The use of these products varied among medical centres. Newborns were most frequently exposed to the odour of aqueous alcoholic solutions.

CONCLUSIONS

Vulnerable preterm infants are daily exposed to multiple NOs most of them be considered as irritant for the nose. Minimizing infants' exposure to them would be beneficial. Future studies should describe the exact olfactory properties of the products considered essential for infant care and should assess their effects on the infant's well-being and development.

Developmentally Supportive Care in the Neonatal Intensive Care Unit: An Occupational Therapist’s Role

The role of a pediatric occupational therapist (OT) in the NICU is to provide comprehensive services, including evaluation, treatment, education, decision making, family support, and discharge planning. It may also include early intervention services or outpatient pediatric rehabilitation services. This article will address the need for developmentally supportive care in the NICU, and specifically addresses the role of an OT in this setting. It will explain how crucial collaboration between team members can be in providing quality, comprehensive care for these neonates. In addition, it will address the important role of the parent in this setting for developmentally supportive care while in the NICU and follow-up intervention upon discharge.

The impact of a noise reduction quality improvement project upon sound levels in the open-unit-design neonatal intensive care unit

OBJECTIVE

To decrease measured sound levels in the neonatal intensive care unit through implementation of human factor and minor design modification strategies.

STUDY DESIGN

Prospective time series. Two open-unit-design neonatal centers.

RESULT

Implementation of a coordinated program of noise reduction strategies did not result in any measurable improvement in levels of loudness or quiet.

CONCLUSION

Two centers, using primarily human behavior noise reduction strategies, were unable to demonstrate measurable improvements in sound levels within the occupied open-unit-design neonatal intensive care unit.
