"It Takes a Village" to Implement Family-Centered Care in the Neonatal Intensive Care Unit.

BACKGROUND: Although research has demonstrated positive impacts of family-centered care (FCC), many neonatal intensive care unit (NICU) nurses hesitate to fully engage in its practice. There has been little scientific focus on investigating the challenges of FCC implementation in the NICU setting. PURPOSE: The purpose of this study was to generate a grounded theory explaining the process by which neonatal nurses experience facilitators and challenges through engaging in FCC practices in the context of the NICU setting. METHODS: This qualitative, grounded theory portion of a mixed-methods study employed individual, semistructured, video-based dyadic interviews with 20 neonatal nurses. RESULTS: Successful implementation of FCC by neonatal nurses is affected by various factors. The adage that "it takes a village to raise a child" described this process for the nurse participants. The delivery of FCC involves respectful engagement and participation by multiple internal and external stakeholders. The process of delivering FCC was influenced by factors across 6 categories: equitable relationships, bond of trust, knowledge sharing, empowerment in workplace, environment and culture, and regulations. The findings suggest that FCC implementation is not an individual initiative; rather, it involves a complex set of interrelationships between care team members. NICU nurses may consider these findings when they are proposing a change to a FCC model. IMPLICATIONS FOR PRACTICE AND RESEARCH: Flexibility is necessary by multidisciplinary teams to achieve maximum benefits of FCC and minimize potential harm, despite the unit design. Facilities may support nurses with continuing education programs to expand their FCC knowledge and skills.

The co-occurrence and cumulative prevalence of hypertension, rheumatoid arthritis, and hypothyroidism in preterm-born women in the Women's Health Initiative.

Emerging evidence suggests that preterm-born individuals (<37 weeks gestation) are at increased risk of developing chronic health conditions in adulthood. This study compared the prevalence, co-occurrence, and cumulative prevalence of three female predominant chronic health conditions - hypertension, rheumatoid arthritis [RA], and hypothyroidism - alone and concurrently. Of 82,514 U.S. women aged 50-79 years enrolled in the Women's Health Initiative, 2,303 self-reported being born preterm. Logistic regression was used to analyze the prevalence of each condition at enrollment with birth status (preterm, full term). Multinomial logistic regression models analyzed the association between birth status and each condition alone and concurrently. Outcome variables using the 3 conditions were created to give 8 categories ranging from no disease, each condition alone, two-way combinations, to having all three conditions. The models adjusted for age, race/ethnicity, and sociodemographic, lifestyle, and other health-related risk factors. Women born preterm were significantly more likely to have any one or a combination of the selected conditions. In fully adjusted models for individual conditions, the adjusted odds ratios (aORs) were 1.14 (95% CI, 1.04, 1.26) for hypertension, 1.28 (1.12, 1.47) for RA, and 1.12 (1.01, 1.24) for hypothyroidism. Hypothyroidism and RA were the strongest coexisting conditions [aOR 1.69, 95% CI (1.14, 2.51)], followed by hypertension and RA [aOR 1.48, 95% CI (1.20, 1.82)]. The aOR for all three conditions was 1.69 (1.22, 2.35). Perinatal history is pertinent across the life course. Preventive measures and early identification of risk factors and disease in preterm-born individuals are essential to mitigating adverse health outcomes in adulthood.

Association of Preterm Birth With Prevalent and Incident Hypertension, Early-Onset Hypertension, and Cardiovascular Disease in the Women's Health Initiative.

Increasing evidence suggests preterm birth is a risk factor for hypertension and cardiovascular disease (CVD) in adulthood. Whether there is effect modification by hypertension on CVD risk is unknown. To investigate the associations between preterm birth, hypertension, and incident CVD, we identified 2,303 women aged 50 to 79 years who self-reported being born preterm from the Women's Health Initiative. Using multivariable logistic regression, prevalent hypertension at enrollment, age at hypertension diagnosis, and antihypertensive medication use were compared by birth status (preterm, full-term). Risk of incident hypertension, coronary heart disease, and CVD were analyzed using multivariable Cox proportional-hazard models. Both models adjusted for age, race/ethnicity, education, smoking, physical activity, body mass index, and diabetes mellitus. Significant associations were found between preterm birth and prevalent hypertension (37% vs 33.1%; adjusted odds ratio 1.26 [95% confidence interval (CI) 1.15 to 1.28] p = <0.0001), early-onset hypertension (<50 years) (14.7% vs 11.7%; adjusted odds ratio 1.31, 95% CI 1.15 to 1.48, p = <0.0001), and incident hypertension (53.2% vs 51%; ajusted hazard ratio 1.10, 95% CI 1.03 to 1.19, p = 0.008). Preterm-born women reported taking more antihypertensive medications (2.9% vs 2.6%, p = 0.04). Preterm birth had a nonsignificant association with CVD risk, but when stratified by prevalent hypertension, women born preterm without hypertension had elevated CVD risk compared with women born full-term without prevalent hypertension. Women with prevalent hypertension, preterm and full-term, had similar magnitudes of elevations in CVD risk. In conclusion, preterm birth increases the risk of hypertension and coronary heart disease. With 10% of the population born preterm, birth history should be assessed as a CVD risk factor.

A test of differential susceptibility in behavior trajectories of preterm infants from preschool to adulthood.

Preterm birth predisposes children to internalizing and externalizing behaviors that may persist into adolescence resulting in adult mental health conditions. Social and caregiving contexts, particularly for vulnerable infants born preterm, influence long-term outcomes, but mechanisms are not clearly understood. Healthcare teams caring for those born preterm face difficulty predicting who will be most affected by risk, who will most benefit, and the optimal timing of intervention. Differential susceptibility theory offers an alternative to the traditional risk-only assessments and theories by positing that individuals may be more, or less, susceptible to environmental influences. A sample of preterm- and term-born infants were followed from birth to 23 years of age. Mixed model repeated measures analyses of internalizing and externalizing behaviors were utilized for the comparison groups (N = 214; observations = 1070). Environmental contexts were indexed as proximal protection (low, moderate, high) and medical risk (low, moderate, high). Personal characteristic covariates of sex, race, socioeconomic status, and cognition were modeled. Internalizing behavior trajectories varied significantly over time. Early proximal protective environments conferred a sustained positive influence on behaviors. There is partial support for differential susceptibility theory suggesting that prematurity, as a malleability characteristic enables absorption of both the positive and negative influences of the environment, with greater intensity that those without malleability. The current analyses suggest lasting effects of the preschool age proximal environment on internalizing and externalizing behaviors in young adulthood for those born preterm. Understanding these nuances may aid healthcare professionals in the promotion and timing of interventions to support the child and family. The current manuscript reflects ongoing analyses of longitudinal data. No patient or public contribution to the analyses were required for testing the differential susceptibility theory. The authors would solicit patient or public contribution when implementing practice or policy changes based on the results.

A new cardiovascular disease risk factor for young adults: Preterm birth.

ABSTRACT: Adults born preterm (birth <37 weeks' gestation) have a two-fold increased risk of early cardiovascular mortality. With 10% of the U.S. population born prematurely and perinatal advancements dramatically improving survival rates, millions of survivors are now reaching adulthood. This phenomenon has introduced a whole new population of individuals with a history of preterm birth. Although the prevailing notion has been that preterm birth is a condition confined only to infancy and early childhood, we now know preterm birth is a risk for lifelong chronic health conditions. Despite almost a decade of epidemiological evidence showing increased cardiovascular risk for those born preterm, this has not yet been translated into clinical practice. As a result, clinicians are caring for adults born prematurely without screening and treatment guidelines for this at-risk population and few inquire about birth history during clinical encounters. This brief report presents growing evidence about disrupted cardiogenesis and consequential structural and functional modifications. By asking the question "Were you born preterm?," nurse practitioners can take the first step of increasing their awareness of this at-risk population and mitigate adverse cardiovascular outcomes by using preterm birth as a risk factor when determining health promotion and treatment decisions.

A Protocol to Assess Adult Outcomes at 30 Years Following Preterm Birth.

BACKGROUND: Among the most intense adversity experiences for infants is premature birth. Early birth marks the beginning of a life course that broadly affects families, healthcare, education, social systems, and the survivors themselves. For many, the transition to adulthood is challenging and often hampered by cognitive, physical and mental health, and motor and independence difficulties. OBJECTIVES: The aim of this study was to share a comprehensive protocol of a 10th follow-up study of premature infants in their 30s. The protocol accounts for stress during the neonatal period, the cumulative context (risk and protection) of development, biological and epigenetic mechanisms, and individual resilience. METHODS: The prospective, five-group longitudinal design includes 215 term-born and preterm-born individuals with various neonatal morbidities at ages 30-35 years. Adult outcomes include health, adaptive, executive function, work, and social competence. Novel measures are four system indicators of allostatic load (AL) and epigenetics. Contextual measures include socioeconomic risk and individual resilience. All measures were selected based on coherence with constructs of the scientific aims, strong psychometrics, continuity for repeated measures, and minimal subject burden. Objective assessments include body composition imaging, exercise testing, blood and saliva collection, and actigraphy. The two-phase protocol takes approximately 8 hours. DISCUSSION: After an 11-month COVID-19 pause, participant response has been strong. As of May 2022, 75 participants have completed the full protocol, and 99 have consented to participate. When socioeconomic risk is controlled, we hypothesize that life course trajectories in physical and psychological health, adaptive function, and executive function will differ between term and preterm neonatal morbidity groups. AL will vary across groups and contribute to outcomes. We expect proximal protection and resilience to mediate the cumulative medical and socioeconomic risk and AL. Epigenome-wide DNA methylation, with estimates of age acceleration, will be examined across groups and explored in longitudinal associations with medical risk, socioeconomic status, and protection. To our knowledge, this is the only U.S. study of premature infants aged 30-35 years. With millions of preterm-born individuals reaching adulthood, the protocol incorporates molecular and genetic biomarkers in a life course developmental examination to inform the timing and content of interventions.

Molding influences of prematurity: Interviews with adults born preterm.

BACKGROUND: Tremendous medical advancements over the last several decades have supported the survival of younger and sicker newborns. Substantial quantitative research exists about health and developmental outcomes following preterm birth, however, limited published literature has explored what this experience means to the survivors. AIM: The purpose was to describe, interpret and understand how adults born preterm perceive prematurity to have affected their lives. STUDY DESIGN: Qualitative thematic analysis. METHODS: Semi-structured interviews were conducted with 33 adults born preterm from the RHODE Study, a longitudinal preterm birth cohort. A cross-section of participants with high and low early life medical and environmental risk was interviewed. Data were analyzed using a constructionist method of latent theme analysis. RESULTS: From the data, 3 themes were identified: 1) My parents call me their miracle, 2) It's not a big deal, I'm the same as everyone else, 3) I've overcome a lot. Themes represent a continuum of experience, from positive to neutral to negative. Common life experiences of family, education, friends, and health are subthemes that help to illuminate how participants assign meaning to their prematurity. Meaning was linked to how typical or not participants perceive their health, learning and friends compared to peers. CONCLUSION: Perceptions about prematurity and adversity are influenced by the ways parents and families represent prematurity in shared stories and actions. These findings should inform future research with adult survivors of prematurity. Participants identified ongoing need for support and advocacy, particularly from healthcare and education communities.

Implementation and Practice Barriers of Family-Centered Care Encountered by Neonatal Nurses.

BACKGROUND: Approximately 7 out of every 100 births in the United States result in admission to the neonatal intensive care unit (NICU), which contributes to a delay in initial physical contact between the parents and their newborn. While family-centered care (FCC) increases opportunities for parent-infant connection, implementation barriers persist in clinical practice. Research has yet to examine whether organizational and nursing factors of empowerment and compassion fatigue (CF) in the NICU are associated with FCC practice. PURPOSE: The aim of this study was to determine the relationship between empowerment, CF, and FCC practices among NICU nurses. METHODS: This quantitative portion of a mixed-methods study used a cross-sectional, descriptive correlational design. Bedside NICU nurses with at least 6-month experience were recruited to complete an anonymous online survey using established, valid, and reliable instruments. RESULTS: Except for organizations with Magnet status, there were no significant differences in FCC practice within individual and institutional characteristics. Hierarchical linear regression model indicated nurse empowerment was a strong predictor of FCC practice (ß= 0.31, R2 = 0.35, P < .001). There was only a weak, inverse association between CF and FCC practices ( r =-0.199, P < .001). IMPLICATION FOR RESEARCH AND PRACTICE: Further qualitative research will integrate these findings to understand the process by which neonatal nurses engage in FCC practices in the context of NICU setting. Future studies should examine facilitators and barriers of FCC practice in the NICU. Strategies (eg, policies and trainings) to increase nurse empowerment and support for FCC implementation should be developed and evaluated.

Effects of early life NICU stress on the developing gut microbiome.

Succession of gut microbial community structure for newborns is highly influenced by early life factors. Many preterm infants cared for in the NICU are exposed to parent-infant separation, stress, and pain from medical care procedures. The purpose of the study was to investigate the impact of early life stress on the trajectory of gut microbial structure. Stool samples from very preterm infants were collected weekly for 6 weeks. NICU stress exposure data were collected daily for 6 weeks. V4 region of the 16S rRNA gene was amplified by PCR and sequenced. Zero-inflated beta regression model with random effects was used to assess the impact of stress on gut microbiome trajectories. Week of sampling was significant for Escherichia, Staphylococcus, Enterococcus, Bifidobacterium, Proteus, Streptococcus, Clostridium butyricum, and Clostridium perfringens. Antibiotic usage was significant for Proteus, Citrobacter, and C. perfringens. Gender was significant for Proteus. Stress exposure occurring 1 and 2 weeks prior to sampling had a significant effect on Proteus and Veillonella. NICU stress exposure had a significant effect on Proteus and Veillonella. An overall dominance of Gammaproteobacteria was found. Findings suggest early life NICU stress may significantly influence the developing gut microbiome, which is important to NICU practice and future microbiome research.

Novel method of measuring chronic stress for preterm infants: Skin cortisol.

BACKGROUND AND OBJECTIVES: Infants who begin life in the medicalized environment of the neonatal intensive care unit (NICU) do so under stressful conditions. Environmental exposures are often abrasive to vulnerable infants, while invasive and noninvasive lifesaving interventions provide additional pain and/or stress. The most commonly selected biomarker to measure stress is cortisol. The skin is the barrier between the external environment and communicates with our neurological, endocrine and immune regulatory networks. To examine if skin cortisol may be a reliable biomarker of stress, NICU stress exposure and repeated measurements of skin cortisol in very preterm infants were examined retrospectively during the first 6 weeks of life. The temporal relationship between skin cortisol and NICU stress exposure was also analyzed. MATERIALS AND METHODS: Participants included 82 preterm infants born weighing less than 1500 g, admitted to a level III NICU, with a mean gestational age of 28.5 weeks. Infants were studied from birth through 6 weeks of life. NICU stress data was collected using the Neonatal Infant Stressor Scale. Skin samples were collected using d-squame tape as soon after birth as possible and every two weeks thereafter. RESULTS: On average, infants experienced approximately 43 stressful events per day during the first 6 weeks of life in the NICU. Stress level and cortisol reactivity varied by gestation age. Higher stress resulted in higher cortisol for infant >28 weeks; lower stress scores were associated with higher stress for infants <28 weeks. Stress exposure during 7 days prior to cortisol sampling yielded the highest AUC for the 2 groups. A statistically significant interaction was identified between gestational age and stress exposure during the previous 7 days (p < 0.01). CONCLUSION: This is the first study to demonstrate skin cortisol as a preterm infant biomarker of chronic stress exposure. For infants with appropriate skin maturation, this non-invasive sampling method provides several benefits. Importantly, this method may be less intrusive and disruptive for preterm infants.

Clinician Perceptions of the NICU Infant Experience: Is the NICU Hospitalization Traumatic?

OBJECTIVE: Infants cared for in a newborn intensive care unit (NICU) experience pain, parental separation, and stress that may approach toxic levels, thus are potentially traumatic. Lack of accepted clinical terminology to describe the infant experience may result in under appreciation of NICU hospitalization on infant and family outcomes. This study explored NICU clinician perceptions of the infant experience and how the terms trauma/traumatic would impact their clinical roles and practices. STUDY DESIGN: Semistructured focus group interviews and thematic analysis were used to describe professionals' perceptions of the infant's experience and terminology. Focus groups were organized by professional role, including NICU leadership, physicians, nurses, and ancillary providers. RESULT: Six themes emerged from the qualitative analysis: at our mercy, trauma defined and redefined, and now you have broken them too, perceptions of NICU experience change over time, trauma in the NICU: whose trauma is it, and not knowing the infant and family experience. CONCLUSION: While recognizing potentially toxic infant stress levels, clinicians are reluctant to describe the NICU infant experience as traumatic. Hesitations relate to clinicians' personal concerns that they may be seen as agents of trauma and the impact for families if the NICU experience was described as traumatic by clinicians.

FKBP5 genotype and early life stress exposure predict neurobehavioral outcomes for preterm infants.

PROBLEM: This study evaluated the relationship between stressful early life neonatal intensive care unit (NICU) experiences, genetic variation of a stress response-associated gene (FKBP5), and neurobehavioral outcomes. METHOD: The impact of genetic variation and stress experience on neurobehavioral outcomes was examined for 41 preterm infants. Statistical analyses explored the main effects of FKBP5 genotype and NICU stress experience, as well as their interaction on infant neurobehavioral development prior to discharge. RESULTS: Statistical analyses demonstrated a relationship between both FKPB5 genotype and stress related to NICU care that were independently associated with neurobehavioral outcomes; indicating a main effect of genotype and a main effect of stress on neurodevelopment. Additionally, we found an interaction between the minor allele genotype and NICU stress potentially associated with less favorable developmental progress at discharge. IMPLICATIONS: Evidence of genetic and environmental risk factors for neurodevelopmental impairment suggests the need for improved evidence-based practice initiatives to protect those most vulnerable to the combination of genetic susceptibility to stress and medical fragility.

UNPACKING THE BURDEN OF CARE FOR INFANTS IN THE NICU.

Infants who begin early life in the medicalized environment of the neonatal intensive care unit (NICU) experience disruption to numerous fundamental expectancies. In the NICU, infants are exposed to chronic, extreme stressors that include painful medical procedures and parental separation. Due to their preverbal stage of development, infants are unable to fully express these experiences, and linking these experiences to long-term outcomes has been difficult. This clinical article proposes the terminology Infant Medical Trauma in the NICU (IMTN) to describe the infant experience. Following a discussion of the NICU as an adverse childhood event, the article has three sections: (a) the unique and critical factors that define the newborn period, (b) a review of the IMTN conceptual model, and (c) recommendations for supportive neuroprotective strategies to moderate the intensity of adverse NICU infant experiences.
