Neonatal Intensive Care Unit Environment Research Articles

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

To describe the supporting and enhancing neonatal intensive care unit (NICU) sensory experiences (SENSE) program, associated research and opportunities for further study. 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. 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. The literature related to the SENSE program is promising, but more research on efficacy and implementation is needed.

The effect of developmental care on the length of hospital stay and family centered care practice for very low birth weight infants in neonatal intensive care units: A cluster randomized controlled trial

BackgroundDespite previous studies suggesting that developmental care can provide benign stimulation to promote neural development of newborns, more evidence is needed regarding the other clinical benefits of developmental care. ObjectiveTo evaluate the effect of implementing developmental care on the length of hospital stay, the improvement of care practice in neonatal intensive care units, as well as the short-term outcome of very low birth weight infants. DesignCluster-randomized controlled trial. Setting(s) and participantsFrom March 1, 2021 to March 1, 2022, 1400 very low birth weight infants were recruited from 14 tertiary neonatal intensive care units in China. MethodsWe assigned 14 neonatal intensive care units to either developmental care or standard care. The length of hospital stay of the infants was the primary outcome analyzed at the individual level. Secondary outcomes were family centered care practice including parental involvement, the skin to skin care, exclusive breast milk, oral immune therapy and breastfeeding. The environmental management (noise and light) and the short-term outcomes were also evaluated. ResultsThe length of hospital stay for the developmental care group was 65 % as long as that for the control group (HR: 0.65, 95 % CI, 0.451–0936, p = 0.021). After controlling the covariables, the adjusted HR = 0.755 (95 % CI, 0.515 to 1.107, p = 0.150). When compared to the control group, the developmental care group had greater access to SSC, with 22 infants (3.8 %) in the developmental care group compared to 13 infants (1.7 %) in the standard care group (p = 0.013). A greater proportion of infants in the developmental care group were fed at the breast, than those in the standard care group (136 [23.6 %] vs 9 [1.1 %]; p = 0.029). Compared to the control group, exclusively breast milk was significantly more favorable in the developmental care group (435 [75.6 %] vs 114 [15.0 %]; p = 0.001). The difference remained significant even after adjusting for covariates. However, the rate of oral immune therapy and parental involvement was similar in the two groups. The average noise and light levels in the developmental care group were significantly lower than those in the standard care group. After adjusting for confounders, the difference remained significant. There were no significant differences among groups in the mortality and major morbidity. ConclusionsDevelopmental care might have developed an accumulated effect over time on the length of hospital stay among very low birth weight infants. The implementation of developmental care can greatly improve family centered care practices and the neonatal intensive care unit environment. RegistrationClinicalTrials.govNCT05166720.

Breastfeeding Barriers for Preterm Infants in Neonatal Intensive Care Unit Environments: A Systematic Assessment and Meta-Analysis.

Background: Breast milk is vital for the growth and development of preterm infants. However, in Neonatal Intensive Care Units (NICUs), mothers often encounter significant challenges in breastfeeding. Objective: This study aims to systematically evaluate the barriers to breastfeeding in NICUs, thereby providing evidence-based support for clinical practices. Methods: A comprehensive search was conducted in the Cochrane Library, PubMed, Web of Science, Embase, and Scopus databases, up to September 2023. Meta-analysis was performed using Stata 15.0, applying fixed or random effects models to calculate odds ratios (OR) and their 95% confidence intervals (CI). Study quality was assessed using the Newcastle-Ottawa Scale for cases and cohorts and the Agency for Healthcare Research and Quality standards for cross-sectional studies. Heterogeneity was evaluated using Cochran's chi-squared test (Cochran's Q) and I2 statistics, and publication bias was assessed through funnel plots and symmetry tests. Results: A total of 32 studies were included, encompassing 96,053 preterm infants. The main barriers to breastfeeding in preterm infants included: low gestational age (OR = 1.36, 95% CI: 1.06-1.75), lower maternal education (OR = 1.64, 95% CI: 1.39-1.93), insufficient breast milk (OR = 2.09, 95% CI: 1.39-1.93), multiple births (OR = 1.615, 95% CI: 1.18-2.210), smoking (OR = 2.906, 95% CI: 2.239-3.771), and single motherhood (OR = 1.439, 95% CI: 1.251-1.654). Conclusion: This study underscores the need for individualized breastfeeding support strategies in NICUs, taking into account the diverse backgrounds of mothers. Future research should focus on unraveling the underlying mechanisms affecting breastfeeding in preterm infants, with the goal of enhancing breastfeeding rates and improving developmental outcomes.

Stress and self-regulation behaviors in preterm neonates hospitalized at open-bay and single-family room Neonatal Intensive Care Unit

The Neonatal Intensive Care Unit (NICU) could be a risk factor for the development of preterm neonates due to the stressful procedures they undergo. Stress-related behaviors must be managed through environmental strategies that support regulating the neonates' biobehavioural system to minimize the negative impact on their development. The study aimed to compare the NICU environment's stressful procedures and developmental care strategies and the stress and self-regulation behaviors of preterm neonates in groups differentiated by the NICU environmental design. The sample comprised 20 preterm neonates hospitalized in a NICU with an open-bay model (OB NICU) and 20 preterm neonates hospitalized in a single-family room model (SFR NICU). The stressful procedures were assessed by the Neonatal Infant Stressor Scale (NISS). The developmental care strategies and the preterm neonates' stress and self-regulation behaviors were assessed using a structured observational protocol. The between-group comparison was performed by the Mann-Whitney test, and the significance level was set at 5%. Both NICUs had similar stressful procedures and developmental care approaches. However, the preterm neonates hospitalized in the SFR NICU exhibited significantly fewer total stress behaviors, and specifically in the motor system, compared to those in the OB NICU. Additionally, the preterm neonates hospitalized in the SFR NICU exhibited significantly more total self-regulation behaviors, and specifically in the behavioral state system, compared to those in the OB NICU. The findings showed that the single-family room NICU model was consistent with the environmental protection of biobehavioural regulation in preterm neonates hospitalized in the NICU.

Joint observation in NICU (JOIN): A randomized controlled trial testing an early, one-session intervention during preterm care to improve perceived maternal self-efficacy and other mental health outcomes.

Parents of preterm infants in the Neonatal Intensive Care Unit (NICU) environment may experience psychological distress, decreased perceived self-efficacy, and/or difficulties in establishing an adaptive parent-infant relationship. Early developmental care interventions to support the parental role and infant development are essential and their impact can be assessed by an improvement of parental self-efficacy perception. The aims were to assess the effects of an early intervention provided in the NICU (the Joint Observation) on maternal perceived self-efficacy compared to controls (primary outcome) and to compare maternal mental health measures (perceived stress, anxiety, and depression), perception of the parent-infant relationship, and maternal responsiveness (secondary outcomes). This study was a monocentric randomized controlled trial registered in clinicatrials.gov (NCT02736136), which aimed at testing a behavioural intervention compared with treatment-as-usual. Mothers of preterm neonates born 28 to 32 6/7 weeks gestation were randomly allocated to either the intervention or the control groups. Outcome measures consisted of self-report questionnaires completed by the mothers at 1 and 6 months after enrollment and assessing perceived self-efficacy, mental health, perception of the parent-infant relationship and responsiveness, as well as satisfaction with the intervention. No statistically significant group effects were observed for perceived maternal self-efficacy or the secondary outcomes. Over time, perceived maternal self-efficacy increased for mothers in both groups, while anxiety and depression symptoms decreased. High satisfaction with the intervention was reported. The joint observation was not associated with improved perceived maternal self-efficacy or other mental health outcomes, but may constitute an additional supportive measure offered to parents in a vulnerable situation during the NICU stay.

Explore Parent’s Perception Regarding Role of Nurse as an Educator in an Intensive Care Unit Punjab Pakistan: A Qualitative Study

Background: The neonatal intensive care unit (NICU) environment is highly stressful for both neonates and their family caregivers. The quality of interaction between caregivers and medical staff can significantly influence caregiver trust and satisfaction, which are crucial for the effective care and recovery of the neonate. Objective: This study aims to assess the perceptions of family caregivers regarding the role of nurses as educators in a NICU in Punjab, Pakistan, focusing on the communication strategies employed by nurses and the support infrastructure available to caregivers. Methods: This qualitative study involved semi-structured interviews with 14 family caregivers of neonates hospitalized in the Allama Iqbal Teaching Hospital's NICU. Participants were selected based on their intensive involvement in the care of their hospitalized newborns. Data were analyzed using content analysis to explore the themes related to nursing care quality as perceived by the caregivers. Results: Caregivers generally perceived the nursing care as excellent, noting particularly the professionalism and empathy of the nursing staff. However, issues such as inadequate hospital infrastructure, particularly sleeping facilities for caregivers, and occasional lapses in communication and caregiving flexibility were identified as areas needing improvement. The study also highlighted the critical role of timely and accurate information provided to caregivers in reducing anxiety and enhancing their involvement in the care process. Conclusion: Effective communication and adequate support infrastructure are essential in enhancing caregiver trust and satisfaction in the NICU setting. Improving these areas can significantly impact the recovery and well-being of both neonates and their families.

Epidemiology of carbapenem-resistant Acinetobacter baumannii colonization in neonatal intensive care units: A systematic review and meta-analysis

BACKGROUND The rising prevalence of carbapenem-resistant Acinetobacter baumannii (CRAB) in neonatal intensive care units (NICUs) represents an escalating challenge in healthcare settings, particularly in managing hospital-acquired infections (HAIs). Studies across various World Health Organization regions have documented a significant incidence of CRAB-related HAIs, with rates as high as 41.7 cases per 1000 patients in ICUs, accounting for 13.6% of all HAIs. These infections pose a doubled mortality risk compared to infections with carbapenem-susceptible Acinetobacter baumannii . A particularly concerning aspect of CRAB colonization is its asymptomatic nature, enabling its transmission through healthcare workers (HCWs) or the NICU environment to vulnerable neonates with developing immune systems. AIM To explore the prevalence of CRAB colonization in NICUs, focusing on neonates, healthcare workers, and the environmental samples, to enhance epidemiological understanding and inform targeted interventions. METHODS We conducted according to PRISMA 2020 checklist guidelines, a comprehensive literature search across multiple databases including MEDLINE (Ovid), EMBASE (Ovid), Global Health (Ovid), Web of Science, and Global Index Medicus. Studies were selected based on predetermined criteria, primarily involving neonates, HCWs, and environmental swabs, using culture or molecular methods to detect CRAB colonization. We excluded studies that did not specifically focus on NICUs, were duplicates, or lacked necessary data. The study selection and quality assessment were conducted independently by two reviewers. Data extraction involved collecting comprehensive details about each study. Our statistical analysis used a random-effects model to calculate the pooled prevalence and confidence intervals, stratifying results by regional location. We assessed study heterogeneity using Cochran's Q statistic and I ² statistic, with regression tests employed to evaluate potential publication bias. RESULTS We analyzed 737 records from five databases, ultimately including 13 studies from ten countries. For neonates, the pooled prevalence was 4.8% (95%CI: 1.1% to 10.5%) with the highest rates observed in South-East Asia (10.5%; 95%CI: 2.4% to 23.3%). Among HCWs, a single Indian study reported a 3.3% prevalence. Environmental samples showed a prevalence of 2.3% (95%CI: 0% to 9.3%), with the highest rates in South-East Asia (10%; 95%CI: 4.2% to 17.7%). Significant heterogeneity was found across studies, and no publication bias was detected. CONCLUSION This systematic review highlights a significant prevalence of CRAB colonization in neonates across various regions, particularly in South-East Asia, contrasting with lower rates in high-income countries. The study reveals a gap in research on HCWs colonization, with only a single study from India reporting moderate prevalence. Environmental samples indicate moderate levels of CRAB contamination, again higher in South-East Asia. These findings underscore the need for more extensive and focused research on CRAB colonization in NICUs, including exploring the roles of HCWs and the environment in transmission, understanding antimicrobial resistance patterns, and developing effective prevention measures.

OVERCOMING DISTANCE: VIRTUAL VISIT OF SIBLINGS IN A NEONATAL ICU IN THE CONTEXT OF THE COVID-19 PANDEMIC: CASE REPORT

Due to the Covid-19 pandemic, several changes were implemented to ensure neonatal care, including restricting access to the Neonatal Intensive Care Unit (NICU) to parents only. This study aimed to discuss the possibility of siblings visiting the NICU through the use of Information and Communication Technologies (ICTs) during the pandemic. The methodology used was a case study, with the participation of two babies admitted to the NICU of a public health unit in Rio de Janeiro. The results showed greater interaction among babies, observed through their body movements and facial expressions in response to visual and auditory stimuli from their siblings, using mobile devices. The visit also allowed the siblings to experience, even remotely, the NICU environment, as they did not expect the new family member to be hospitalized after birth. It was concluded that this type of visit can be used to expand visitation to other family members, such as grandparents, or to those who live far from the hospital. In this way, the virtual visit can function as a health device to facilitate humanization processes, guaranteeing the rights of the baby and his family, even beyond the context of the pandemic.

Perspectives on Device-Facilitated Therapy in Management of Pediatric Dysphagia in the Neonatal Intensive Care Unit

Purpose: Most infants born preterm will experience some difficulty with sucking and feeding. As clinicians in the neonatal intensive care unit (NICU), it is important to understand the available technologies so that they may be implemented, when appropriate and accessible, to support these infants in their sucking and feeding performance. The purpose of this review is to highlight devices that are available to assist clinicians in the management of pediatric dysphagia in the NICU. We will review the literature surrounding the use of devices in the management of pediatric dysphagia. This is followed by a clinical perspective from a NICU speech-language pathologist (SLP) who shares important considerations, recommendations, and limitations of device use. Conclusions: By reviewing device-facilitated therapies for the management of pediatric dysphagia and discussing their implementation and effectiveness, we hope that SLPs will gain an understanding of the available technologies and insight into their use in the NICU environment. While the research highlighted shows many benefits of the use of device-facilitated therapies in the NICU, this is an emerging area of the field that is continually evolving and more research is needed to establish the pathway to individualized, developmentally supportive, device-facilitated intervention.

A Feasibility Study to Test the NICU Paternal Needs Inventory.

There has been little research exploring paternal needs while experiencing a neonatal intensive care unit (NICU) stay. Some tools exist to measure paternal needs, but do not incorporate items to capture important information about how fathers cope with stress differently, and may have different needs. Therefore, an instrument is needed to measure and prioritize what needs are important to fathers to help facilitate the development of nursing interventions to help fathers cope with the NICU environment. The purpose of this study was to conduct a feasibility study before large-scale pilot testing the instrument, the NICU Paternal Needs Inventory (NPNI), so we could then determine what are the physical, emotional, and psychological needs of fathers. A nonexperimental, quantitative, and descriptive design was used to address the study's aims. Fathers were recruited from a level IV NICU and asked to complete an online survey (consisting of a demographic survey and the NPNI). Needs rated 100% were knowing infant's progress, directions on caring for infant, flexible visitation, and assurance receiving the best care. The remainder showed a wide range of responses suggesting that needs of fathers are individual and varied. Use of the NPNI to evaluate a father's unique and individual needs would allow for the nurse to develop father-specific, individualized interventions. Findings support that the NPNI is feasible to accomplish measuring fathers' needs, but a larger study is needed to test the reliability and validity of this tool.

Trauma Informed Care in the Neonatal Intensive Care Unit

Parents who have a baby receiving care in the Neonatal Intensive Care Unit (NICU) likely all experience emotional distress and are at elevated risk of experiencing trauma. The NICU environment is a potential source of traumatic stress for parents and often the risk for neonatal death is substantial. While the stressors facing parents are considerable, the effects can be minimized through implementation of trauma-informed care. The Family Guidance Tool was developed to help parents and healthcare professionals in a NICU setting utilize a strengths-based approach to create an atmosphere of mutual trust and understanding while encouraging the family to be the guide. This practical tool shows promise to mitigate stress often experienced by parents in a NICU setting.

Effects of the neonatal intensive care environment on circadian health and development of preterm infants.

The circadian system in mammals ensures adaptation to the light-dark cycle on Earth and imposes 24-h rhythmicity on metabolic, physiological and behavioral processes. The central circadian pacemaker is located in the brain and is entrained by environmental signals called Zeitgebers. From here, neural, humoral and systemic signals drive rhythms in peripheral clocks in nearly every mammalian tissue. During pregnancy, disruption of the complex interplay between the mother's rhythmic signals and the fetal developing circadian system can lead to long-term health consequences in the offspring. When an infant is born very preterm, it loses the temporal signals received from the mother prematurely and becomes totally dependent on 24/7 care in the Neonatal Intensive Care Unit (NICU), where day/night rhythmicity is usually blurred. In this literature review, we provide an overview of the fetal and neonatal development of the circadian system, and short-term consequences of disruption of this process as occurs in the NICU environment. Moreover, we provide a theoretical and molecular framework of how this disruption could lead to later-life disease. Finally, we discuss studies that aim to improve health outcomes after preterm birth by studying the effects of enhancing rhythmicity in light and noise exposure.

Detection, survival, and persistence of Staphylococcus capitis NRCS-A in neonatal units in England

The multidrug-resistant Staphylococcus capitis clone, NRCS-A, is increasingly associated with late-onset sepsis in low birthweight newborns in neonatal intensive care units (NICUs) in England and globally. Understanding where this bacterium survives and persists within the NICU environment is key to developing and implementing effective control measures. To investigate the potential for S.capitis to colonize surfaces within NICUs. Surface swabs were collected from four NICUs with and without known NRCS-A colonizations/infections present at the time of sampling. Samples were cultured and S.capitis isolates analysed via whole-genome sequencing. Survival of NRCS-A on plastic surfaces was assessed over time and compared to that of non-NRCS-A isolates. The bactericidal activity of commonly used chemical disinfectants against S.capitis was assessed. Of 173 surfaces sampled, 40 (21.1%) harboured S.capitis with 30 isolates (75%) being NRCS-A. Whereas S.capitis was recovered from surfaces across the NICU, the NRCS-A clone was rarely recovered from outside the immediate neonatal bedspace. Incubators and other bedside equipment were contaminated with NRCS-A regardless of clinical case detection. In the absence of cleaning, S.capitis was able to survive for three days with minimal losses in viability (<0.5 log10 reduction). Sodium troclosene and a QAC-based detergent/disinfectant reduced S.capitis to below detectable levels. S.capitis NRCS-A can be readily recovered from the NICU environment, even in units with no recent reported clinical cases of S.capitis infection, highlighting a need for appropriate national guidance on cleaning within the neonatal care environment.

Communication Barriers to Implementation of Family-Centered Care from Perspective of Mothers and Personnel of Neonatal Intensive Care Unit: A Qualitative Study

Background: Positive communication between staff and parents is considered a basic principle for the successful implementation of family-centered care (FCC) and the formation of a good relationship between parents and neonates. Moreover, involvement in care depends on the communication and interaction of parents with healthcare providers, and cooperation between them leads to high-quality care for neonates. However, interaction and communication are still considered major challenges in the neonatal intensive care unit (NICU) environment. Since these challenges and communication barriers are different in various cultures and environments, they should be identified in the field. A literature review shows that no study has assessed the views of different members of the treatment team and parents on communication barriers in Iran. Objectives: The present study aimed to investigate the communication barriers related to personnel and parents for implementing FCC from the perspective of parents, physicians, nurses, and nursing managers. Methods: A qualitative study was conducted in 2021 - 2022 using the conventional content analysis approach in a NICU in Tehran, Iran. In this study, 26 semi-structured interviews and 10 field notes were used to collect data to reach data saturation. Results: Data analysis led to the emergence of two themes. The first theme was the unprofessional relationships of personnel, including two main categories of inappropriate professional behavior and lack of attention to personnel and working conditions of the ward. The second theme was mutually ineffective relationships between personnel and parents, including two main categories of the inappropriate attitude of personnel and parents toward each other and unsympathetic communication between personnel and parents. The themes showed the participants’ experiences of communication barriers to the implementation of FCC in NICUs in Iran. Conclusions: Removing communication barriers between healthcare providers and parents requires developing a coherent, comprehensive, and unified training program to prepare and create integrated coordination among the treatment team and the family, creating a positive attitude toward FCC and the presence of parents, improving relationships, and giving further attention and support by managers to personnel and the conditions of the ward.

Incubator-based active noise control device: comparison to ear covers and noise reduction zone quantification

BackgroundNoise exposure in the neonatal intensive care unit (NICU) is consistently higher than current recommendations. This may adversely affect neonatal sleep, weight gain, and overall health. We sought to evaluate the effect of a novel active noise control (ANC) system.MethodsAn ANC device’s noise reduction performance was compared to that of adhesively affixed foam ear covers in response to alarm and voice sounds in a simulated NICU environment. The zone of noise reduction of the ANC device was quantified with the same set of alarm and voice sounds.ResultsThe ANC device provided greater noise reduction than the ear covers in seven of the eight sound sequences tested in which a noise reduction greater than the just noticeable difference was achieved. For noise in the 500 Hz octave band, the ANC device exhibited consistent noise reduction throughout expected patient positions. It provided better performance for noise below 1000 Hz than above 1000 Hz.ConclusionsThe ANC device provided generally superior noise reduction to the ear covers and provided a zone of noise reduction throughout the range where an infant would be placed within an incubator. Implications for patient sleep and weight gain are discussed.ImpactActive noise control device can effectively reduce noise inside an infant incubator due to bedside device alarms.This is the first analysis of an incubator-based active noise control device and comparison to adhesively affixed silicone ear covers.A non-contact noise reduction device may be an appropriate means of reducing noise exposure of the hospitalized preterm infant.

Implementing an exclusive human milk diet for preterm infants: real-world experience in diverse NICUs

BackgroundHuman milk–based human milk fortifier (HMB-HMF) makes it possible to provide an exclusive human milk diet (EHMD) to very low birth weight (VLBW) infants in neonatal intensive care units (NICUs). Before the introduction of HMB-HMF in 2006, NICUs relied on bovine milk–based human milk fortifiers (BMB-HMFs) when mother's own milk (MOM) or pasteurized donor human milk (PDHM) could not provide adequate nutrition. Despite evidence supporting the clinical benefits of an EHMD (such as reducing the frequency of morbidities), barriers prevent its widespread adoption, including limited health economics and outcomes data, cost concerns, and lack of standardized feeding guidelines.MethodsNine experts from seven institutions gathered for a virtual roundtable discussion in October 2020 to discuss the benefits and challenges to implementing an EHMD program in the NICU environment. Each center provided a review of the process of starting their program and also presented data on various neonatal and financial metrics associated with the program. Data gathered were either from their own Vermont Oxford Network outcomes or an institutional clinical database. As each center utilizes their EHMD program in slightly different populations and over different time periods, data presented was center-specific. After all presentations, the experts discussed issues within the field of neonatology that need to be addressed with regards to the utilization of an EHMD in the NICU population.ResultsImplementation of an EHMD program faces many barriers, no matter the NICU size, patient population or geographic location. Successful implementation requires a team approach (including finance and IT support) with a NICU champion. Having pre-specified target populations as well as data tracking is also helpful. Real-world experiences of NICUs with established EHMD programs show reductions in comorbidities, regardless of the institution’s size or level of care. EHMD programs also proved to be cost effective. For the NICUs that had necrotizing enterocolitis (NEC) data available, EHMD programs resulted in either a decrease or change in total (medical + surgical) NEC rate and reductions in surgical NEC. Institutions that provided cost and complications data all reported a substantial cost avoidance after EHMD implementation, ranging between $515,113 and $3,369,515 annually per institution.ConclusionsThe data provided support the initiation of EHMD programs in NICUs for very preterm infants, but there are still methodologic issues to be addressed so that guidelines can be created and all NICUs, regardless of size, can provide standardized care that benefits VLBW infants.

Experiences of Mothers of Preterm Infants in the Neonatal Intensive Care Unit During the COVID-19 Pandemic.

The neonatal intensive care unit (NICU) stay following the birth of a preterm infant can be stressful and traumatic for families. During the COVID-19 pandemic, the NICU environment changed precipitously as infection control and visitor restriction measures were implemented. Our study aimed to examine the impact of the pandemic policies on the experiences of mothers of preterm infants during their stay in the NICU. Semistructured interviews were conducted with mothers of preterm infants hospitalized in a Canadian tertiary-level NICU. Informed by interpretive description methodology, interview content was transcribed and analyzed using a thematic analysis approach. The identified themes were validated, clarified, or refined using investigator triangulation. Nine English-speaking mothers, aged 28 to 40 years, were interviewed. Four themes emerged from the analysis of their experiences: (1) disrupted family dynamic, support, and bonding; (2) physical and emotional isolation; (3) negative psychological impact compounded by added concerns, maternal role change, and survival mode mentality; and (4) positive aspects of the pandemic management measures. During the pandemic, the way that care was provided in the NICU changed. This study helps to explore how neonatal clinicians can foster individual and organizational resilience to keep patients and families at the center of care, even when the healthcare system is under intense stress. : Our results show that these changes heightened mothers' distress, but also had a modest positive impact. Further research about long-term consequences of pandemic policies on the mother and preterm infant after NICU discharge is warranted.

Living in a box: Understanding acoustic parameters in the NICU environment.

In the last years, a significant body of scientific literature was dedicated to the noisy environment preterm-born infants experience during their admission to Neonatal Intensive Care Units (NICUs). Nonetheless, specific data on sound characteristics within and outside the incubator are missing. Therefore, this study aimed to shed light on noise level and sound characteristics within the incubator, considering the following domain: environmental noise, incubator handling, and respiratory support. The study was performed at the Pediatric Simulation Center at the Medical University of Vienna. Evaluation of noise levels inside and outside the incubator was performed using current signal analysis libraries and toolboxes, and differences between dBA and dBSPL values for the same acoustic noises were investigated. Noise level results were furthermore classed within previously reported sound levels derived from a literature survey. In addition, sound characteristics were evaluated by means of more than 70 temporal, spectral, and modulatory timbre features. Our results show high noise levels related to various real-life situations within the NICU environment. Differences have been observed between A weighted (dBA) and unweighted (dBSPL) values for the same acoustic stimulus. Sonically, the incubator showed a dampening effect on sounds (less high frequency components, less brightness/sharpness, less roughness, and noisiness). However, a strong tonal booming component was noticeable, caused by the resonance inside the incubator cavity. Measurements and a numerical model identified a resonance of the incubator at 97 Hz and a reinforcement of the sound components in this range of up to 28 dB. Sound characteristics, the strong low-frequency incubator resonance, and levels in dBSPL should be at the forefront of both the development and promotion of incubators when helping to preserve the hearing of premature infants.

Interventional Effect of Quiet Time Protocol on the Physiological Parameters of Premature Neonates Admitted to the Neonatal Intensive Care Unit

Background: Premature neonates are a group of high-risk patients who need intensive medical care and hospitalization in the neonatal intensive care unit (NICU) for their survival. In the NICU environment, there are highly stressful stimuli that have a negative effect on the physiological parameters of premature neonates. One of the interventions that improve the physiological parameters of neonates is the implementation of the quiet time protocol. Objectives: The present study aimed to investigate the effect of the quiet time protocol intervention on the physiological parameters of premature neonates admitted to the NICU. Methods: This quasi-experimental study was performed on 62 premature neonates selected through a convenient sampling method out of the neonates admitted to the NICU. First, the samples of the control group were collected. A demographic data questionnaire was employed. Neonates in the two groups were examined for 60 min during three phases before, during, and after the intervention in the evening shift of 15 - 17 o’clock. Data were analyzed using the SPSS software version 22 by the chi-squared test, repeated measures analysis of variance (ANOVA), and t-test. P-value &lt; 0.05 was considered statistically significant. Results: The results of repeated measures ANOVA regarding arterial blood oxygen saturation (SaO2) percentage showed that changes over time were significant (P &lt; 0.001). There was also a significant difference between the groups in terms of intervention effect (P = 0.004). In other words, the changes in SaO2 percentage were not the same in the two groups, and the changes in the score of the intervention group were higher than the control group. The results of repeated measures ANOVA showed that the changes in the heart rate and respiratory rate over time were significant (P &lt; 0.001). Conclusions: The quiet time protocol is effective in reducing environmental stimuli and improving physiological parameters. Therefore, the implementation of these procedures during each 8-hour shift, that includes a specific period which light, sound, and bedside stimulation is controllably reduced, is recommended as a standard of care to reduce stress and improve the growth and development of premature neonates in the NICU.

Examining Efficiency in Open-Bay and Single-Family Room NICU Designs.

There is growing awareness of the relationship between physical work environments and efficiency. Two conflicting factors shape efficiency in the neonatal intensive care unit (NICU) environment: the move to single-family rooms (SFRs) and increased demand for care, requiring growth in unit size. The goal of this research was to understand the impact of SFR NICUs on efficiency factors such as unit design, visibility and proximity, staff time, and workspace usage by various health professionals. A pre-/postoccupancy evaluation assessed a NICU moving from an open-bay to an SFR unit composed of 6 neighborhoods. A NICU patient care manager and researchers in design and communication implemented a multimethodological design using staff surveys, observations, and focus groups. Outcomes revealed SFR NICUs contribute to increased efficiency and overall satisfaction with design. Outside of staff time spent in patient rooms, decentralized nurse stations were the most frequented location for staff work, followed by huddle stations, medication and supply rooms, and corridors. Work at the observed locations was largely performed independently. Survey outcomes reported increased feelings of isolation, but focus groups revealed mixed opinions regarding these concerns. Design solutions found to enhance efficiency include a neighborhood unit design, standardized access to medications and supplies, and proximity of supplies, patient rooms, and nurse workstations. Although feelings of isolation were reported and most staff work was done independently in the patient room, the SFR unit might not be the culprit when considered alongside staff's desire to be closer to the patient room.
