Early Amino Acids in Extremely Preterm Infants and Neurodisability at 2 Years.

BACKGROUND: Whether higher parenteral amino acid intake improves outcomes in infants with extremely low birth weight is unclear. METHODS: In this multicenter, parallel-group, double-blind, randomized, placebo-controlled trial, we assigned infants with birth weights of less than 1000 g at 8 neonatal intensive care units to receive amino acids at a dose of 1 g per day (intervention group) or placebo in addition to usual nutrition for the first 5 days after birth. The primary outcome was survival free from neurodisability as assessed with the Bayley Scales of Infant and Toddler Development and neurologic examination at 2 years, corrected for gestational age at birth. Secondary outcomes were the components of the primary outcome as well as the presence or absence of neonatal disorders, the rate of growth, and nutritional intake. RESULTS: We enrolled 434 infants (217 per group) in this trial. Survival free from neurodisability was observed in 97 of 203 children (47.8%) in the intervention group and in 102 of 205 (49.8%) in the placebo group (adjusted relative risk, 0.95; 95% confidence interval [CI], 0.79 to 1.14; P = 0.56). Death before the age of 2 years occurred in 39 of 217 children (18.0%) in the intervention group and 42 of 217 (19.4%) in the placebo group (adjusted relative risk, 0.93; 95% CI, 0.63 to 1.36); neurodisability occurred in 67 of 164 children (40.9%) in the intervention group and 61 of 163 (37.4%) in the placebo group (adjusted relative risk, 1.16; 95% CI, 0.90 to 1.50). Neurodisability was moderate to severe in 27 children (16.5%) in the intervention group and 14 (8.6%) in the placebo group (adjusted relative risk, 1.95; 95% CI, 1.09 to 3.48). More children in the intervention group than in the placebo group had patent ductus arteriosus (adjusted relative risk, 1.65; 95% CI, 1.11 to 2.46). In a post hoc analysis, refeeding syndrome occurred in 42 of 172 children in the intervention group and 26 of 166 in the placebo group (adjusted relative risk, 1.64; 95% CI, 1.09 to 2.47). Eight serious adverse events occurred. CONCLUSIONS: In infants with extremely low birth weight, extra parenteral amino acids at a dose of 1 g per day for 5 days after birth did not increase the number who survived free from neurodisability at 2 years.

Discrete glucose profiles identified using continuous glucose monitoring data and their association with adverse pregnancy outcomes.

BACKGROUND: Continuous glucose monitoring has facilitated the evaluation of dynamic changes in glucose throughout the day and their effect on fetal growth abnormalities in pregnancy. However, studies of multiple continuous glucose monitoring metrics combined and their association with other adverse pregnancy outcomes are limited. OBJECTIVE: This study aimed to (1) use machine learning techniques to identify discrete glucose profiles based on weekly continuous glucose monitoring metrics in pregnant individuals with pregestational diabetes mellitus and (2) investigate their association with adverse pregnancy outcomes. STUDY DESIGN: This study analyzed data from a retrospective cohort study of pregnant patients with type 1 or 2 diabetes mellitus who used Dexcom G6 continuous glucose monitoring and delivered a nonanomalous, singleton pregnancy at a tertiary center between 2019 and 2023. Continuous glucose monitoring data were collapsed into 39 weekly glycemic measures related to centrality, spread, excursions, and circadian cycle patterns. Principal component analysis and k-means clustering were used to identify 4 discrete groups, and patients were assigned to the group that best represented their continuous glucose monitoring patterns during pregnancy. Finally, the association between glucose profile groups and outcomes (preterm birth, cesarean delivery, preeclampsia, large-for-gestational-age neonate, neonatal hypoglycemia, and neonatal intensive care unit admission) was estimated using multivariate logistic regression adjusted for diabetes mellitus type, maternal age, insurance, continuous glucose monitoring use before pregnancy, and parity. RESULTS: Of 177 included patients, 90 (50.8%) had type 1 diabetes mellitus, and 85 (48.3%) had type 2 diabetes mellitus. This study identified 4 glucose profiles: (1) well controlled; (2) suboptimally controlled with high variability, fasting hypoglycemia, and daytime hyperglycemia; (3) suboptimally controlled with minimal circadian variation; and (4) poorly controlled with peak hyperglycemia overnight. Compared with the well-controlled profile, the suboptimally controlled profile with high variability had higher odds of a large-for-gestational-age neonate (adjusted odds ratio, 3.34; 95% confidence interval, 1.15-9.89). The suboptimally controlled with minimal circadian variation profile had higher odds of preterm birth (adjusted odds ratio, 2.59; 95% confidence interval, 1.10-6.24), cesarean delivery (adjusted odds ratio, 2.76; 95% confidence interval, 1.09-7.46), and neonatal intensive care unit admission (adjusted odds ratio, 4.08; 95% confidence interval, 1.58-11.40). The poorly controlled profile with peak hyperglycemia overnight had higher odds of preeclampsia (adjusted odds ratio, 2.54; 95% confidence interval, 1.02-6.52), large-for-gestational-age neonate (adjusted odds ratio, 3.72; 95% confidence interval, 1.37-10.4), neonatal hypoglycemia (adjusted odds ratio, 3.53; 95% confidence interval, 1.37-9.71), and neonatal intensive care unit admission (adjusted odds ratio, 3.15; 95% confidence interval, 1.20-9.09). CONCLUSION: Discrete glucose profiles of pregnant individuals with pregestational diabetes mellitus were identified through joint consideration of multiple continuous glucose monitoring metrics. Prolonged exposure to maternal hyperglycemia may be associated with a higher risk of adverse pregnancy outcomes than suboptimal glycemic control characterized by high glucose variability and intermittent hyperglycemia.

Physicochemical compatibility of caffeine citrate and caffeine base injections with parenteral medications used in neonatal intensive care settings.

PURPOSE: To investigate the physicochemical compatibility of caffeine citrate and caffeine base injections with 43 secondary intravenous (IV) drugs used in Neonatal Intensive Care Unit (NICU) settings. METHODS: Caffeine citrate (20 mg/mL or 10 mg/mL) or caffeine base injection (10 mg/mL) were mixed in a volume ratio of 1:1 with the secondary drug solution to simulate Y-site co-administration procedures in NICUs. Physical compatibility was evaluated based on visual observation for 2 h, against a black and white background and under polarised light, for changes in colour, precipitation, haze and evolution of gas. Chemical compatibility was determined from caffeine concentration measurements, using a validated high-performance liquid chromatography assay. RESULTS: Six of the 43 secondary drugs tested (aciclovir, amphotericin (liposomal), furosemide, hydrocortisone, ibuprofen and ibuprofen lysine) were physically incompatible with caffeine citrate undiluted injection (20 mg/mL), at their high-end, clinically relevant concentrations for NICU settings. However, when tested at lower concentrations, hydrocortisone (1 mg/mL) was physicochemically compatible, whereas furosemide (0.2 mg/mL) was physically incompatible with caffeine citrate. The six drugs which showed physical incompatibility with caffeine citrate 20 mg/mL injection were also physically incompatible with caffeine citrate 10 mg/mL solution. All 43 secondary drugs tested were physicochemically compatible with caffeine base injection. CONCLUSIONS: Most secondary test drugs, except aciclovir, amphotericin (liposomal), furosemide, hydrocortisone, ibuprofen and ibuprofen lysine, were physicochemically compatible with caffeine citrate injection. Caffeine base injection was physicochemically compatible with all 43 test drugs tested.

How is bioelectrical impedance used in neonatal intensive care? A scoping review.

Poor growth and nutrition management in the neonatal period can have a negative impact upon both the short- and long-term outcomes for the infant. Improvements in bioelectrical impedance technology and accompanying licencing agreements now make this enhanced device available for use in infants as small as 23 weeks gestational age. An exploration of this technology and its use is now timely. The aim of the scoping review was to answer the following question: in preterm and sick term infants in the neonatal intensive care unit, how is bioelectrical impedance being utilized, in what situations, and when? The scoping review was conducted using Arksey and O'Malley's (Int J Soc Res Methodol 8(1):19-32, 2005) framework. Forty-nine papers were initially identified and 16 were included in the scoping review. Three studies were experimental designs, and 13 were observational studies. The review found that BIA was used in neonatal intensive care in three main ways, for, (1) fluid status evaluation, (2) as a measure of adequate nutrition and growth, (3) to validate the technology as an outcome measure in neonates. CONCLUSION: There is a paucity of recent robust research papers which investigate the use of bioelectrical impedance in preterm neonates. Available evidence spans a range of 30 years, with technological advancement reducing the application of older studies to the modern neonatal setting. Although this technology may be helpful for decision-making around fluid management and nutrition, in preterm infants, robust evidence is needed to demonstrate the clinical benefit of bioelectrical impedance beyond that of usual care. WHAT IS KNOWN: • Clinical decisions regarding neonatal nutrition and fluid management are currently based upon the interpretation of vital signs, fluid balance, weight trend, biochemical markers, and physical examination. • Bioelectrical Impedance Analysis (BIA) is a non-invasive method of assessing body composition which is now available to be used in infants as small as 23 weeks gestation. WHAT IS NEW: • Bioelectrical Impedance has been used in three main ways in the NICU, for fluid status evaluation, for measuring nutrition and growth and to validate BIA as an outcome. • There is a lack of recent robust research data to support the use of the device within clinical decision making in neonatal intensive care.

Analysis of noise levels in the neonatal intensive care unit: the impact of clinical microsystems.

Reorganization of neonatal intensive care by introducing clinical microsystems may help to allocate nursing time more appropriately to the needs of patients. However, there is concern that cohorting infants according to acuity may enhance noise levels. This single-center study investigated the impact of reorganization of neonatal intensive care unit by implementing clinical microsystems in a Level III NICU on environmental noise. This prospective study measured 24-h noise levels over a period of 6 months during pre- and post-implementation of microsystems cohorting infants of similar acuity. Comparative analyses of the mixed acuity (i.e., before) and the cohorting (i.e., after) model were performed by creating daily profiles from continuous noise level measurements and calculating the length of exposure to predefined noise levels. Compared to baseline daytime measurements, noise levels were 3-6 dBA higher during physician handover. Noise levels were 2-3 dBA lower on weekends and 3-4 dBA lower at night, independent of the organizational model. The introduction of clinical microsystems slightly increased average noise levels for high-acuity pods (A and B) but produced a much more substantial decrease for low-acuity pods (E), leading to an overall reduction in unit-wide noise levels.    Conclusion: Our data show that noise levels are more driven by human behavior than by technical devices. Implementation of microsystems may help to reduce noise exposure in the lower acuity pods in a NICU. What is Known: • Excessive noise levels can lead to adverse effects on the health and development of premature infants and other critically ill newborns. • The reorganization of the neonatal intensive care unit following the clinical microsystems principles might improve quality of care but also affect noise exposure of staff and patients. What is New: • The transition from a mixed -acuity to cohorting model is associated with an overall reduction in noise levels, particularly in low-acuity pods requiring less nursing care. • Nevertheless, baseline noise levels in both models exceeded the standard permissible limits.

Assessing fluid responsiveness with ultrasound in the neonatal intensive care setting: the mini-fluid challenge.

The mini-fluid challenge (MFC) can guide individualised fluid therapy and prevent fluid overload and associated morbidity in adult intensive care patients. This ultrasound test is based on the Frank-Starling principles to assess dynamic fluid responsiveness, but limited MFC data exists for newborns. This brief report describes the feasibility of the MFC in 12 preterm infants with late onset sepsis and 5 newborns with other pathophysiology. Apical views were used to determine the changes in left ventricular stroke volume before and after a 3 ml/kg fluid bolus was given over 5 min. Four out of the 17 infants were fluid responsive, defined as a post-bolus increase in stroke volume of 15% or more.  Conclusion: The MFC was feasible and followed the physiological principles of stroke volume and extravascular lung water changes and 24% were fluid responsive. The MFC could enable future studies to examine whether adding fluid responsiveness to guide fluid therapy in newborns can reduce the risk of fluid overload. What is Known: • Fluid overload is associated with morbidity and mortality. • The mini-fluid challenge (MFC) provides a personalised approach to fluid therapy. What is New: • The MFC is feasible in newborns. • The MFC followed the physiological principles of stroke volume and extravascular lung water changes.

Cardiac point-of-care ultrasound: Practical integration in the pediatric and neonatal intensive care settings.

Cardiac point-of-care ultrasound (POCUS) is a technology increasingly leveraged at the bedside by pediatric critical care and neonatology providers to identify real-time hemodynamic pathophysiology. We present a framework for (1) identifying the scope of cardiac POCUS within the clinical practice setting, (2) standardizing views for protocolized hemodynamic assessment relevant to pediatric critical illness and (3) integrating POCUS findings for therapeutic guidance. Within the review, we also discuss practical strengths and limitations to image acquisition and interpretation within the varied cardiac POCUS views. Finally, we explore unique considerations within the neonatal population.    Conclusion: Cardiac POCUS is a technology and tool that reveals important real-time information at the bedside of the critically ill child and infant. Understanding strengths and limitations of cardiac POCUS views and protocolizing an approach to answer focused clinical questions provides a framework for training and translation to clinical care. What is Known: • Ultrasound technology is now ubiquitous among pediatric critical care and neonatology settings, and growing literature supports an expanded role in not only procedural but also diagnostic applications. • Cardiac POCUS influences provider perception of pathophysiology and changes clinical management. What is New: • Effective cardiac POCUS training and subsequent translation to clinical practice should improve when clinical questions and protocolized approaches to image acquisition are standardized within a specialty. • Cardiac POCUS views have strengths and limitations which must be recognized when assessing the hemodynamic profile of a child or neonate.

Continuous renal replacement therapy in neonates and children: what does the pediatrician need to know? An overview from the Critical Care Nephrology Section of the European Society of Paediatric and Neonatal Intensive Care (ESPNIC).

Continuous renal replacement therapy (CRRT) is the preferred method for renal support in critically ill and hemodynamically unstable children in the pediatric intensive care unit (PICU) as it allows for gentle removal of fluids and solutes. The most frequent indications for CRRT include acute kidney injury (AKI) and fluid overload (FO) as well as non-renal indications such as removal of toxic metabolites in acute liver failure, inborn errors of metabolism, and intoxications and removal of inflammatory mediators in sepsis. AKI and/or FO are common in critically ill children and their presence is associated with worse outcomes. Therefore, early recognition of AKI and FO is important and timely transfer of patients who might require CRRT to a center with institutional expertise should be considered. Although CRRT has been increasingly used in the critical care setting, due to the lack of standardized recommendations, wide practice variations exist regarding the main aspects of CRRT application in critically ill children.     Conclusion: In this review, from the Critical Care Nephrology section of the European Society of Paediatric and Neonatal Intensive Care (ESPNIC), we summarize the key aspects of CRRT delivery and highlight the importance of adequate follow up among AKI survivors which might be of relevance for the general pediatric community. What is Known: • CRRT is the preferred method of renal support in critically ill and hemodynamically unstable children in the PICU as it allows for gentle removal of fluids and solutes. • Although CRRT has become an important and integral part of modern pediatric critical care, wide practice variations exist in all aspects of CRRT. What is New: • Given the lack of literature on guidance for a general pediatrician on when to refer a child for CRRT, we recommend timely transfer to a center with institutional expertise in CRRT, as both worsening AKI and FO have been associated with increased mortality. • Adequate follow-up of PICU patients with AKI and CRRT is highlighted as recent findings demonstrate that these children are at increased risk for adverse long-term outcomes.

Neuromonitoring in neonatal intensive care units-an important need towards individualized neuroprotective care.

Neuromonitoring has been widely accepted as an important part in neonatal care. Amplitude-integrated EEG (aEEG) and near-infrared spectroscopy (NIRS) are often mentioned in this context, though being only a part of the fully array of methods and examinations that could be considered neuromonitoring. Within the broad array of medical conditions that could be encountered in a neonatal patient, it is important to be aware of the indications for neuromonitoring and especially which neuromonitoring technique to use best for the individual condition. aEEG is now a widely accepted neuromonitor in neonatology with its value in hypoxic events and seizures only rarely questioned. Other methods like NIRS still have to prove themselves in the future. The SafeBoosC-III trial showed that it still remains difficult for some of these methods to prove their value for the improvement of outcome. Bute future developments such as multimodal neuromonitoring with data integration and artificial intelligence analysis could improve the value of these methods.

The effect of paternal anxiety on mother-infant bonding in neonatal intensive care.

BACKGROUND: The hospitalization of a preterm infant in the NICU can lead to mental health difficulties in parents, but not much is known how paternal anxiety might affect the mother-infant relationship. METHODS: This prospective cohort study is a secondary analysis investigating how paternal anxiety levels might affect maternal bonding in the NICU using the dataset of the multinational pragmatic randomized controlled trial LongSTEP. A linear mixed-effects model was used for correlations of paternal anxiety (GAD-7) and maternal bonding (PBQ) at NICU discharge, and at 6 and 12 months infant corrected age. Secondary analyses examined effects on paternal anxiety related to: site (Argentina, Colombia, Israel, Norway, and Poland), maternal depression (EPDS), infant gestational age at birth, paternal age, and type of pregnancy. RESULTS: Paternal anxiety did not predict maternal bonding at NICU discharge (p = 0.096), at 6 months (p = 0.316), or at 12 months infant corrected age (p = 0.473). Secondary outcomes showed a statistically significant site effect, with higher paternal anxiety levels at the two Colombian sites at baseline (p = 0.014 and p = 0.020) and for one site at discharge (p = 0.012), but not for paternal age (p = 0.925 and p = 0.793), infant gestational age at birth (p = 0.974 and p = 0.686 and p = 0.340), or type of pregnancy (p = 0.381). Maternal depression predicted paternal anxiety at baseline (p < 0.001) and at discharge (p = 0.003). CONCLUSIONS: In this study, paternal anxiety did not predict maternal bonding. Paternal anxiety varied by site, indicating a need for research on potential cultural differences in manifestation of paternal anxiety. Maternal depression predicted paternal anxiety, confirming a previously reported correlation. Further research on variations in paternal mental health in the neonatal period is warranted, as well as exploration of the social contagion of mental health in preterm parents.

Music therapy in tertiary neonatal intensive care: A matter of unlikely allies?

Over the past decades, music therapy in the neonatal intensive care unit (NICU) has been proven effective in physiological and psychological outcomes, including sucking, behaviour, stress reduction, neurodevelopment and promoting emotional bonding. However, not every NICU administers music therapy in their ward. Research on music therapy for neonates and their caregivers has lately accumulated, increasing the evidence of health benefits on brain development and across a variety of NICU-related pathologies, including neurological, cardiological, pulmonary and gastrointestinal problems. Conclusively, we will present the studied methods of music therapy for clinical benefits in neonatal intensive care.

Transient abnormal myelopoiesis requiring advanced neonatal intensive care treatment.

AIM: Five to thirty percent of neonates with trisomy 21 develop transient abnormal myelopoiesis (TAM) with a high mortality rate. The aim of the study was to identify contributing factors that determine mortality and need for chemotherapy in this patient group. METHODS: Six-year, single-centre, retrospective study of neonatal TAM cases requiring admission to intensive care. Data were collected from electronic patient records, laboratory and genetic results. The odds ratio was calculated to assess the likelihood of neonates with certain clinical characteristics having short-term mortality and needing chemotherapy. RESULTS: Twenty-one neonates were studied with a mortality rate of 28%. Neonates requiring inotropic support (OR 19, 95% CI: 0.9-399, p = 0.05) and inhaled nitric oxide (iNO) (OR 13, 95% CI: 1.4-124.3, p = 0.03) were less likely to survive to discharge. Neonates needing mechanical ventilation (OR 14, 95% CI: 1.1-185.5, p = 0.04), or a white cell count >50 × 109/L (OR 27, 95% CI: 1.2-605.7, p = 0.04) were more likely to receive chemotherapy. CONCLUSION: A high mortality rate was identified in TAM neonates with symptomatic pulmonary hypertension (PH) needing active treatment strategies, such as inotropes and iNO. The presence of PH should be considered in the clinical management, prognosis and parental counselling.

Family Management Skills Reported by Parents of Preterm Infants in the NICU Using the Self- and Family Management Framework (SFMF).

BACKGROUND: Across the globe, family-integrated care (FICare) has become an evidence-based standard in which parents deliver the majority of infant care in the neonatal intensive care unit (NICU). Because of extensive barriers to parent presence, adaptations to FICare may be required for successful implementation. Family management theory may provide structure to the Parent Education of FICare and help nurses guide parents' skill development as equal care members. PURPOSE: To identify family management skills employed by NICU parents using the Self- and Family Management Framework (SFMF). METHODS: We conducted secondary analyses of qualitative interview data from NICU parents (n = 17) who shared their experiences of using family management skills to care for their infant. We categorized skills according to 3 main self- and family management processes: Focusing on Infant Illness Needs; Activating Resources; and Living With Infant Illness. RESULTS: Parents reported several family management skills currently identified in the SFMF, as well as new skills such as conflict management, power brokerage, and addressing resources related to social determinants of health. Parent activation of resources was critical to sustaining parent focus on the infant's illness needs. IMPLICATIONS FOR PRACTICE AND RESEARCH: By teaching skills that parents reported as helping them manage infant care, neonatal nurses may better facilitate parent integration into the care team. Future researchers can incorporate the skills identified in this study into the design of family management interventions that facilitate FICare implementation in the United States.

Exploring Parent Experiences With Early Palliative Care Practices in the NICU.

BACKGROUND: The anxiety and uncertain outcome of an admission of a seriously ill infant to the neonatal intensive care unit (NICU) can cause great stress for parents and contribute to poor mental health outcomes. Early implementation of family-centered palliative care (PC) may provide support for NICU parents. Key concepts of early PC in the NICU include shared decision-making, care planning, and support for coping with distress. PURPOSE: The purpose of this study was to explore parent experiences during their child's NICU admission with the early PC practices of shared decision-making, care planning, and coping with distress. METHODS: Qualitative descriptive methodology was used. Strategies of reflexive journaling, peer debriefing, and data audits were used to enhance trustworthiness. Parents (N = 16) were interviewed, and data were analyzed by conventional content analysis. Targeted recruitment of fathers occurred to ensure they comprised 25% of sample. RESULTS: Parents' descriptions of decision-making were contextualized in gathering information to make a decision, the emotional impact of the decision, and influences on their decision-making. In experiences with care planning, parents described learning to advocate, having a spectator versus participant role, and experiencing care planning as communication. Key themes expressed regarding parental coping were exposure to trauma, survival mode, and a changing support network. IMPLICATIONS FOR PRACTICE AND RESEARCH: These findings highlight key areas for practice improvement: providing more support and collaboration in decision-making, true engagement of parents in care planning, and encouraging peer support and interaction in the NICU and in online communities.

Neonatal intensive care nurses' accounts of care for mothers/families with substance-exposed pregnancies: A critical discourse analysis.

AIMS: To explore the effects of power dynamics and hospital organizational structure upon neonatal intensive care nurses' experiences caring for infants and families from a substance-exposed pregnancy (SEP). DESIGN: This secondary data analysis further investigated the results of a primary study after the original analysis suggested differences in work environments may impact relationship-building opportunities between nurses and mothers/families. Critical discourse analysis served as both the theoretical lens and analytic technique. METHOD: Nine (9) nurses from the southeast region of the United States (U.S.) were interviewed in 2019. Fifty-one (51) stories of caregiving experiences were analysed with a focus on narratives related to organizational structure and care delivery. RESULTS: Study findings revealed nurses experienced challenges providing high-quality, family-centered care for patients in the neonatal intensive care unit (NICU) affected by substances during pregnancy. Nurses described the central challenge of workload, exacerbated by power imbalances and structural constraints within the hospital's organizational structure. Findings suggest workload issues may endorse stigma by inhibiting opportunities to build relationships. Nurses report manageable workloads can support healthcare teams and recipients of care. CONCLUSION: The study suggests power imbalances between nurses, families and adjacent healthcare professionals can inhibit the delivery of high-quality care. Supporting healthcare teams and recipients of care while centering the role of organizational structure is critical. Questions emerged about workload demands impacting the potential production of stigma in clinical environments. IMPACT: This study examines the intersection of nurses' care experiences and hospital organizational structure. It identifies how the unique needs of caring for infants and families from a SEP increase the complexity of power imbalances and organizational constraints to further increase workload demands. Findings have implications for global healthcare organization leaders who build and maintain the structural integrity of clinical environments and nurse leaders who advocate and guide clinical teams to provide high-quality care in stressful healthcare environments. REPORTING METHOD: EQUATOR guidelines were followed, using the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION: NICU nurses were interviewed about their care-provision experiences. Interviews were analysed in the primary study and the current analysis of secondary data.

Evaluating the Effectiveness of Brief Training for Neonatal Intensive Care Nurses on the Prevention of Medical Device-Related Nasal Pressure Injury.

OBJECTIVE: To evaluate the effectiveness of a brief training in medical device-related pressure injury (MDRPI) prevention for neonatal intensive care nurses. METHODS: This single-group, pretest-posttest quasi-experimental study was conducted between April and October 2021 with 81 nurses working in the neonatal ICU of a city hospital. The participants completed a training program consisting of two 40-minute sessions that used a small-group problem-based learning approach developed in accordance with evidence-based research. Data were collected using a neonatal nurse information form, knowledge of MDRPI in preterm infants form, and training evaluation form, all of which were prepared for this study based on the literature. Data collection was performed before the training and repeated at 1 week and 1 month after the training. Data analysis was performed using the Number Cruncher Statistical System. Descriptive statistics, the Shapiro-Wilk test, Mann-Whitney U test, and Spearman correlation analysis were used. RESULTS: The participants' mean score on the knowledge of MDRPI in premature infants form was 82.44 ± 7.26 before training and increased significantly to 94.57 ± 5.03 at 1 week and 94.67 ± 3.11 at 1 month after training (P = .001 and P = .001, respectively). No significant relationship was detected between the participants' descriptive characteristics and their knowledge scores before or after the training (P > .05). CONCLUSIONS: Brief training on the prevention of nasal pressure injury caused by noninvasive ventilation increased nurses' knowledge level.

Neonatal intensive care admission for term neonates and subsequent childhood mortality: a retrospective linkage study.

BACKGROUND: Neonatal intensive care unit (NICU) admission among term neonates is a rare event. The aim of this study was to study the association of the NICU admission of term neonates on the risk of long-term childhood mortality. METHODS: A single-center case-control retrospective study between 2005 and 2019, including all in-hospital ≥ 37 weeks' gestation singleton live-born neonates. The center perinatal database was linked with the birth and death certificate registries of the Israeli Ministry of Internal Affairs. The primary aim of the study was to study the association between NICU admission and childhood mortality throughout a 15-year follow-up period. RESULTS: During the study period, 206,509 births were registered; 192,527 (93.22%) term neonates were included in the study; 5292 (2.75%) were admitted to NICU. Throughout the follow-up period, the mortality risk for term neonates admitted to the NICU remained elevated; hazard ratio (HR), 19.72 [14.66, 26.53], (p < 0.001). For all term neonates, the mortality rate was 0.16% (n = 311); 47.9% (n = 149) of those had records of a NICU admission. The mortality rate by time points (ratio1:10,0000 births) related to the age at death during the follow-up period was as follows: 29, up to 7 days; 20, 7-28 days; 37, 28 days to 6 months; 21, 6 months to 1 year; 19, 1-2 years; 9, 2-3 years; 10, 3-4 years; and 27, 4 years and more. Following the exclusion of congenital malformations and chromosomal abnormalities, NICU admission remained the most significant risk factor associated with mortality of the study population, HRs, 364.4 [145.3; 913.3] for mortality in the first 7 days of life; 19.6 [12.1; 32.0] for mortality from 28 days through 6 months of life and remained markedly elevated after age 4 years; HR, 7.1 [3.0; 17.0]. The mortality risk related to the NICU admission event, adjusted for admission diagnoses remained significant; HR = 8.21 [5.43; 12.4]. CONCLUSIONS: NICU admission for term neonates is a pondering event for the risk of long-term childhood mortality. This group of term neonates may benefit from focused health care.

The Potential Impact of Preemptive Pharmacogenetic Genotyping in the Neonatal Intensive Care Unit.

OBJECTIVE: To evaluate the use of drugs with pharmacogenomic (PGx) guidelines from the Clinical Pharmacogenetics Implementation Consortium in early childhood. STUDY DESIGN: A retrospective observational study of patients admitted to the neonatal intensive care (NICU) between 2005 and 2018 with at least 1 subsequent hospitalization at or after 5 years of age was performed to determine PGx drug exposure. Data regarding hospitalizations, drug exposures, gestational age, birth weight, and congenital anomalies and/or a primary genetic diagnosis were collected. Incidence of PGx drug and drug class exposures was determined and patient specific factors predictive of exposure were investigated. RESULTS: During the study, 19 195 patients received NICU care and 4196 (22%) met study inclusion; 67% received 1-2, 28% 3-4, and 5% 5 or more PGx-drugs in early childhood. Preterm gestation, low birth weight (<2500 g), and the presence of any congenital anomalies and/or a primary genetic diagnosis were statistically significant predictors of Clinical Pharmacogenetics Implementation Consortium drug exposures (P < .01, P < .01, P < .01, respectively). CONCLUSIONS: Preemptive PGx testing in patients in the NICU could have a significant impact on medical management during the NICU stay and throughout early childhood.

Survival and Long-Term Outcomes of Children Who Survived after End-of-Life Decisions in a Neonatal Intensive Care Unit.

OBJECTIVE: To investigate long-term outcomes of infants who survive despite life-and-death discussions with families and a decision to withdraw or withhold life-sustaining interventions (WWLST) in one neonatal intensive care unit. STUDY DESIGN: Medical records for neonatal intensive care unit admissions from 2012 to 2017 were reviewed for presence of WWLST discussions or decisions, as well as the 2-year outcome of all children who survived. WWLST discussions were prospectively recorded in a specific book; follow-up to age 2 years was determined by retrospective chart review. RESULTS: WWLST discussions occurred for 266 of 5251 infants (5%): 151 (57%) were born at term and 115 (43%) were born preterm. Among these discussions, 164 led to a WWLST decision (62%) and 130 were followed by the infant's death (79%). Of the 34 children (21%) surviving to discharge after WWLST decisions, 10 (29%) died before 2 years of age and 11 (32%) required frequent medical follow-up. Major functional limitations were common among survivors, but 8 were classified as functionally normal or with mild-to-moderate functional limitations. CONCLUSIONS: When a WWLST decision was made in our cohort, 21% of the infants survived to discharge. By 2 years of age, the majority of these infants had died or had major functional limitations. This highlights the uncertainty of WWLST decisions during neonatal intensive care and the importance of ensuring that parents are informed of all possibilities. Additional studies including longer-term follow-up and ascertaining the family's views will be important.

The Relationship Between Regional Growth in Neonatal Intensive Care Capacity and Perinatal Risk.

BACKGROUND: The supply of US neonatal intensive care unit (NICU) beds and neonatologists is known to vary markedly across regions, but there have been no investigation of patterns of recent growth (1991-2017) in NICUs in relation to newborn need. OBJECTIVE: The objective of this study was to test the hypothesis that greater growth in NICU capacity occurred in neonatal intensive care regions with higher perinatal risk. RESEARCH DESIGN: A longitudinal ecological analysis with neonatal intensive care regions (n=246) as the units of analysis. Associations were tested using linear regression. SUBJECTS: All US live births ≥400 g in 1991 (n=4,103,528) and 2017 (n=3,849,644). MEASURES: Primary measures of risk were the proportions of low-birth weight and very low-birth weight newborns and mothers who were Black or had low educational attainment. RESULTS: Over 26 years, the numbers of NICU beds and neonatologists per live birth increased 42% and 200%, respectively, with marked variation in growth across regions (interquartile range: 0.3-4.1, beds; neonatologists, 0.4-1.0 per 1000 live births). A weak association of capacity with perinatal risk in 1991 was absent in 2017. There was no meaningful (ie, clinical or policy relevant) association between regional changes in capacity and regions with higher perinatal risk or lower capacity in 1991; higher increases in perinatal risk were not associated with higher capacity growth. CONCLUSION: The lack of association between newborn medical needs and the supply of NICU resources raises questions about the current effectiveness of newborn care at a population level.
