RESUMEN
OBJECTIVE: To evaluate associations between neonatal risk factors and pulmonary vein stenosis (PVS) among infants born preterm with severe bronchopulmonary dysplasia (sBPD). STUDY DESIGN: We performed a case-control study of infants born from 2010 to 2022 at < 32 weeks' gestation with sBPD among 46 neonatal intensive care units in the Children's Hospitals Neonatal Consortium. Cases with PVS were matched to controls using epoch of diagnosis (2010-2016; 2017-2022) and hospital. Multivariable logistic regression analyses were utilized to evaluate PVS association with neonatal risk factors. RESULTS: From 10,171 preterm infants with sBPD, we identified 109 cases with PVS and matched those to 327 controls. The prevalence of PVS (1.07%) rose between epochs (0.8% in 2010-2016 to 1.2% in 2017-2022). Relative to controls, infants with PVS were more likely to be <500 grams at birth, to be small for gestational age <10th%ile (SGA), or have surgical necrotizing enterocolitis (NEC), atrial septal defects (ASD), or pulmonary hypertension (PH). In multivariable models, these associations persisted, and SGA, surgical NEC, ASD, and PH were each independently associated with PVS. Among infants on respiratory support at 36 weeks' postmenstrual age, infants with PVS had 4.3-fold higher odds of receiving mechanical ventilation at 36 weeks' postmenstrual age. Infants with PVS also had 3.6-fold higher odds of in-hospital mortality relative to controls. CONCLUSIONS: In a large cohort of preterm infants with sBPD, multiple independent, neonatal risk factors are associated with PVS. These results lay important groundwork for the development of targeted screening to guide the diagnosis and management of PVS in preterm infants with sBPD.
RESUMEN
OBJECTIVE: To determine the association between indoor air pollution and respiratory morbidities in children with bronchopulmonary dysplasia recruited from the multicenter Bronchopulmonary Dysplasia (BPD) Collaborative. STUDY DESIGN: A cross-sectional study was performed among participants less than 3 years old in the BPD Collaborative Outpatient Registry. Indoor air pollution was defined as any reported exposure to tobacco or marijuana smoke, electronic cigarette emissions, gas stoves, and/or wood stoves. Clinical data included acute care use and chronic respiratory symptoms in the past 4 weeks. RESULTS: A total of 1,011 subjects born at a mean gestational age of 26.4 ± 2.2 weeks were included. Most (66.6%) had severe BPD. Over 40% of subjects were exposed to at least one source of indoor air pollution. The odds of reporting an emergency department visit (OR 1.7 [1.18, 2.45], antibiotic use (OR 1.9 [1.12, 3.21]), or a systemic steroid course (OR 2.18 [1.24, 3.84]) were significantly higher in subjects reporting exposure to secondhand smoke (SHS) compared with those without SHS exposure. Subjects reporting exposure to air pollution (not including SHS) also had a significantly greater odds (OR 1.48 [1.08, 2.03]) of antibiotic use as well. Indoor air pollution exposure (including SHS) was not associated with chronic respiratory symptoms or rescue medication use. CONCLUSION: Exposure to indoor air pollution, especially SHS, was associated with acute respiratory morbidities, including ED visits, antibiotics for respiratory illnesses, and systemic steroid use.
RESUMEN
Objective: To determine whether screening for social determinants of health (SDoH) in a level IV neonatal intensive care unit (NICU) could uncover additional family needs. Methods: Secondary analysis of a prospective study in a level IV NICU. Participants filled out the Protocol for Responding to and Assessing Patients' Assets, Risks and Experiences (PRAPARE) tool, which includes economic, housing, transportation, and safety questions. Questionnaires were completed via secure tablet; the research team notified social workers of reported needs. Illness and demographic characteristics were compared between families who did and did not report resource needs. Manual chart review assessed subsequent response to reported SDoH needs. Results: Of 319 respondents, 61(19%) reported resource needs. Of 61 families, 88% received repeat social work encounter to re-assess for resources; 59% received new resource referrals. Conclusions: Systematic SDoH screening can identify needs throughout the NICU stay, even among families already connected to social work support.
RESUMEN
Multidisciplinary bronchopulmonary dysplasia (BPD) programs provide improved and consistent medical management, care of the developing infant, family support, and smoother transitions in care resulting in improved survival, pulmonary, and extra-pulmonary outcomes. This review summarizes the benefits of interdisciplinary BPD management, as well as strategies for initial programmatic development, program growth, and maintenance at centers across the United States factoring in institutional, provider, and parent reported goals that were derived from a consensus conference on BPD management.
RESUMEN
Over 75% of surviving extremely preterm infants do not have major neurodevelopmental disabilities; however, more than half face difficulties with communication, coordination, attention, learning, social, and executive function abilities. These "minor" challenges can have a negative impact on educational and social outcomes, resulting in physical, behavioral, and social health problems in adulthood. We will review assessment tools for social-emotional and adaptive functional skills in early childhood as these determine family and early childhood supports. We highlight bronchopulmonary dysplasia as an example of the critical intersections of parental wellbeing, medical and developmental adaptive trajectories in infancy and early childhood, and partnerships between child neurologists and community medical and developmental professionals. We examine studies of engaging parents to promote developmental trajectories, with a focus on supporting parent-child interactions that underlie communication, social-adaptive behaviors, and learning in the first 1000 days of life. Recommendations for neurodevelopmental surveillance and screening of extremely preterm infants can also be applied to infants with other risk factors for altered neurodevelopment.

BACKGROUND: Patients discharged on home oxygen therapy (HOT) for bronchopulmonary dysplasia (BPD) often receive months of this therapy. A previous trial comparing two methods of HOT weaning showed that increased parent involvement in HOT weaning decreased HOT duration. Our outpatient team uses a standard protocol for outpatient HOT weaning, starting at the first clinic visit 4-6 weeks after discharge. AIM: To shorten HOT duration by teaching parents the outpatient HOT weaning process before neonatal intensive care unit (NICU) discharge. METHODS: We launched a quality improvement program in April 2021 for preterm infants with BPD without significant comorbidities who were stable on ≤0.5 L nasal cannula. Eligible infants started the outpatient HOT weaning protocol while inpatient, with education for parents and nurses. The outcome measure was the duration of HOT after discharge. Process measures focused on protocol adherence. Balancing measures included NICU length of stay and appropriateness of parent-directed HOT weaning. RESULTS: During the study period, there were a total of 133 eligible patients discharged on home oxygen, with 75 in the baseline group and 58 in the intervention group. Forty-five (78%) participated in the HOT weaning protocol while inpatient. HOT was reduced from an average of 27 to 12 weeks after May 2021. We observed no change in NICU length of stay or inappropriate HOT weaning. CONCLUSION: Early introduction of HOT weaning with a focus on caregiver education is associated with a decreased duration of HOT.

OBJECTIVE: Understand barriers and facilitators to follow-up care for infants with bronchopulmonary dysplasia (BPD). METHODS: Qualitative study of parents and clinical stakeholders caring for infants with BPD. The interview guide was developed by a mother of a former 23-week preterm infant, neonatologist, pulmonologist, nurse, and qualitative researcher. Purposive sampling obtained a heterogenous sociodemographic and professional cohort. Subjects discussed their experience with BPD, barriers to care, caregiver quality of life and health education. Interviews were audio-recorded, transcribed and coded. Thematic analysis was used. RESULTS: Eighteen parents and 20 stakeholders completed interviews. Family-level themes included pragmatic barriers like transportation being multi-faceted; and caregiving demands straining mental health. System-level themes included caregiver education needing to balance immediate caregiving activities with future health outcomes; and integrating primary care, specialty, and community supports. CONCLUSIONS: Individual and system barriers impact follow-up for infants with BPD. This conceptual framework can be used to measure and improve care.

OBJECTIVE: To describe 3-year post-neonatal intensive care unit (NICU) health care use among children with congenital anomalies discharged home from a level IV NICU. STUDY DESIGN: Retrospective chart review of children with congenital anomalies enrolled in a previous prospective cohort study from 201 to 2020. We assessed hospital readmission rate, number of surgeries, and durable medical equipment (DME) use by type of anomaly. RESULTS: Among 166 infants enrolled in the original study, 158 survived to NICU discharge. One-third of the cohort had a genetic anomaly. Six of 158 patients (4%) died before 3 years of age. More than one-half the children were readmitted within the first 2 years of life, and one-third were readmitted in the third year of life. Readmissions were greatest for those with multiple, musculoskeletal, and central nervous system anomalies and lowest for abdominal-wall defects. Approximately one-half the children underwent surgeries, and this proportion remained constant over the 3-year time. Sixty-two percent of patients received DME at discharge, with gastrostomy tubes being the most common. Gastrostomy tubes were still present in 75% of the patients at 3 years of age. CONCLUSION: Children with congenital anomalies are at risk for increased health care use during early childhood. Those with multiple anomalies, a genetic syndrome, musculoskeletal, and central nervous system anomalies and those discharged with DME are at greatest risk whereas those with abdominal-wall defects are at lowest risk. Provider awareness, high-quality discharge training, parent psychological support, greater assimilation of families in the NICU, and telehealth may be some strategies to better support these families.

OBJECTIVE: To determine how bronchopulmonary dysplasia (BPD) affects health-related quality of life (HRQL) among infants from NICU hospitalization through 1-year postdischarge. STUDY DESIGN: This was a prospective cohort study of infants with BPD and their parents. Parent HRQL was measured with the PedsQL Family Impact Module before NICU discharge and 3- and 12-months post-discharge. At 12 months, parent-reported child health outcomes included questions from the Test of Respiratory and Asthma Control in Kids, Warner Initial Developmental Evaluation of Adaptive and Functional Skills, and National Survey of Children with Special Health Care Needs. HRQL change over time was assessed by multivariable linear regression. RESULTS: Of 145 dyads, 129 (89%) completed 3-month follow-up, and 113 (78%) completed 12-month follow-up. In the NICU, lower HRQL was associated with earlier gestational age, postnatal corticosteroids, outborn status, and gastrostomy tubes. At 3 months, lower HRQL was associated with readmissions and home oxygen use. At 12 months, lower HRQL was associated with parent-reported difficulty breathing, lower developmental scores, and not playing with other children. At 3 and 12 months, 81% of parents reported similar or improved HRQL compared with the NICU period. Parents reporting infant respiratory symptoms experienced less improvement. CONCLUSIONS: BPD affects parent HRQL over the first year. Most parents report similar or better HRQL after discharge compared with the NICU stay. Less improvement is reported by parents of infants experiencing respiratory symptoms at 12 months. Efforts to improve parent HRQL should target respiratory symptoms and social isolation.

BACKGROUND: Stress from preterm infant admission to the neonatal intensive care unit (NICU) is associated with infant and maternal physiologic changes, including endocrine and epigenetic alterations. Little is known about the mechanisms connecting NICU stress to biologic changes, and whether preterm infant and maternal stress are reciprocal. As a preliminary step, feasibility and acceptability of measuring indicators of stress are required. PURPOSE: This study evaluated the feasibility and acceptability of research examining perceptions and biologic markers of stress in premature infant-maternal dyads during and after NICU hospitalization. METHODS: We evaluated study feasibility using a longitudinal descriptive design. Acceptability was measured via a maternal questionnaire. Exploratory data regarding hospitalization, perceptions of stress, social support and social determinants of health, and biologic markers of stress were collected during the first week of life and again 3 months after NICU. RESULTS: Forty-eight mothers were eligible for the study, 36 mothers were approached, 20 mothers consented to participate, and 14 mothers completed data collection. Mothers reported high levels of study acceptability despite also voicing concern about the sharing of genetic data. Exploration of DNA methylation of SLC6A4 in preterm infants was significant for a strong correlation with perception of total chronic stress. IMPLICATIONS FOR PRACTICE AND RESEARCH: Clinical practice at the bedside in the NICU should include standardized screening for and early interventions to minimize stress. Complex research of stress is feasible and acceptable. Future research should focus on linking early life stress with epigenetic alterations and evaluation of the dyad for reciprocity.

RESUMEN
OBJECTIVE: To describe the current practices in invasive patent ductus arteriosus (PDA) closure (surgical ligation or transcatheter occlusion) in very low birth weight (VLBW) infants and changes in patient characteristics and outcomes from 2016 to 2021 among US children's hospitals. STUDY DESIGN: We evaluated a retrospective cohort of VLBW infants (birth weight 400-1499 g and gestational age 22-31 weeks) who had invasive PDA closure within 6 months of age from 2016 to 2021 in children's hospitals in the Pediatric Health Information System. Changes in patient characteristics and outcomes over time were evaluated using generalized linear models and generalized linear mixed models. RESULTS: 2418 VLBW infants (1182 surgical ligation; 1236 transcatheter occlusion) from 42 hospitals were included. The proportion of infants receiving transcatheter occlusion increased from 17.2% in 2016 to 84.4% in 2021 (P < .001). In 2021, 28/42 (67%) hospitals had performed transcatheter occlusion in > 80% of their VLBW infants needing invasive PDA closure, compared with only 2/42 (5%) in 2016. Although median postmenstrual age (PMA) at PDA closure did not change for the overall cohort, PMA at transcatheter occlusion decreased from 38 weeks in 2016 to 31 weeks by 2020, P < .001. Among those infants not intubated prior to PDA closure, extubation within 3 days postprocedure increased over time (yearly adjusted odds ratios of 1.26 [1.08-1.48]). Length of stay and mortality did not change over time. CONCLUSION: We report rapid adoption of transcatheter occlusion for PDA among VLBW infants in US children's hospitals over time. Transcatheter occlusions were performed at younger PMA over time.

INTRODUCTION: Despite bronchopulmonary dysplasia (BPD) being a common morbidity of preterm birth, there is no validated objective tool to assess outpatient respiratory symptom control for clinical and research purposes. METHODS: Data were obtained from 1049 preterm infants and children seen in outpatient BPD clinics of 13 US tertiary care centers from 2018 to 2022. A new standardized instrument was modified from an asthma control test questionnaire and administered at the time of clinic visits. External measures of acute care use were also collected. The questionnaire for BPD control was validated in the entire population and selected subgroups using standard methodology for internal reliability, construct validity, and discriminative properties. RESULTS: Based on the scores from BPD control questionnaire, the majority of caregivers (86.2%) felt their child's symptoms were under control, which did not differ by BPD severity (p = 0.30) or a history of pulmonary hypertension (p = 0.42). Across the entire population and selected subgroups, the BPD control questionnaire was internally reliable, suggestive of construct validity (albeit correlation coefficients were -0.2 to -0.4.), and discriminated control well. Control categories (controlled, partially controlled, and uncontrolled) were also predictive of sick visits, emergency department visits, and hospital readmissions. CONCLUSION: Our study provides a tool for assessing respiratory control in children with BPD for clinical care and research studies. Further work is needed to identify modifiable predictors of disease control and link scores from the BPD control questionnaire to other measures of respiratory health such as lung function testing.

BACKGROUND: Infants with bronchopulmonary dysplasia (BPD) are often prescribed diuretics before the neonatal intensive care unit (NICU) discharge. It is unknown whether outpatient medication weaning strategies affect the duration of home oxygen therapy. METHODS: This was a secondary cohort analysis of infants born <32 weeks gestational age with BPD from 2015 to 2018 discharged from our NICU or regional NICUs, referred to our pulmonary clinic for home oxygen management. We compared three groups: those discharged with no diuretics, diuretics actively weaned (dose decreased), and diuretics passively weaned (dose not adjusted). RESULTS: Out of 125 infants, 116 were included in the analysis. Forty-five infants were discharged without diuretics, 52 infants were discharged with diuretics that were actively weaned, and 19 infants were discharged with diuretics that were passively weaned. Infants who were passively weaned spent the most time on home oxygen (median 28 weeks, interquartile range [IQR] 16-52; p = 0.011); there were no differences in home oxygen duration in infants actively weaned (median 13 weeks, IQR 10-26) versus not on diuretics (median 22 weeks, IQR 12-30, p = 0.285). Multivariable adjustment for other illness characteristics associated with the duration of home oxygen did not change this finding. CONCLUSIONS: Active weaning of diuretics did not prolong the duration of home oxygen, in the setting of a standardized clinical guideline for weaning home oxygen in infants with BPD. These data can serve as baseline information to implement and test standardized strategies for outpatient medication management.

Importance: Anti-vascular endothelial growth factor (VEGF) therapy for retinopathy of prematurity (ROP) has potential ocular and systemic advantages compared with laser, but we believe the systemic risks of anti-VEGF therapy in preterm infants are poorly quantified. Objective: To determine whether there was an association with increased risk of pulmonary hypertension (PH) in preterm infants with ROP following treatment with anti-VEGF therapy as compared with laser treatment. Design, Setting, and Participants: This multicenter retrospective cohort study took place at neonatal intensive care units of 48 children's hospitals in the US in the Pediatric Health Information System database from 2010 to 2020. Participants included preterm infants with gestational age at birth 22 0/7 to 31 6/7 weeks who had ROP treated with anti-VEGF therapy or laser photocoagulation. Exposures: Anti-VEGF therapy vs laser photocoagulation. Main Outcomes and Measures: New receipt of pulmonary vasodilators at least 7 days after ROP therapy was compared between exposure groups, matched using propensity scores generated from preexposure variables, and adjusted for birth year and hospital. The odds of receiving an echocardiogram after 30 days of age was also included to adjust for secular trends and interhospital variation in PH screening. Results: Among 1577 patients (55.9% male) meeting inclusion criteria, 689 received laser photocoagulation and 888 received anti-VEGF treatment (95% bevacizumab, 5% ranibizumab). Patients were first treated for ROP at median 36.4 weeks' postmenstrual age (IQR, 34.6-38.7). A total of 982 patients (491 in each group) were propensity score matched. Good covariate balance was achieved, as indicated by a model variance ratio of 1.15. More infants who received anti-VEGF therapy were treated for PH, but when adjusted for hospital and year, this was no longer statistically significant (6.7%; 95% CI, 2.6-6.9 vs 4.3% 95% CI, 4.4-10.2; adjusted odds ratio, 1.62; 95% CI, 0.90-2.89; P = .10). Conclusions and Relevance: Anti-VEGF therapy was not associated with greater use of pulmonary vasodilators after adjustment for hospital and year. Our findings suggest exposure to anti-VEGF may be associated with PH, although we cannot exclude the possibility of residual confounding based on systemic comorbidities or hospital variation in practice. Future studies investigating this possible adverse effect seem warranted.

Parents of infants in the neonatal intensive care unit (NICU) are at increased risk of developing perinatal post-traumatic stress disorder (PPTSD), a mental health condition known to interfere with healthy parental and infant attachment. Feelings of uncertainty about illness have been theorized as an antecedent to post-traumatic stress, however the relationship has not been explored in parents of infants requiring care in the NICU. The purpose of this prospective study was to explore parental uncertainty during and after NICU discharge and the relationship between uncertainty and PPTSD. The sample consisted of 319 parents during NICU hospitalization and 245 parents at 3 months postdischarge. Parents who screened positive for PPTSD 3 months after hospital discharge reported more uncertainty both while in the NICU and 3 months after hospital discharge (p < 0.001). In parents with a personal or family history of mental illness, the moderated/mediating structural probit analysis showed no direct or indirect effect of uncertainty during hospitalization or at 3 months after hospital discharge on screening positive for PPTSD. In parents who did not report personal or family history of mental illness, uncertainty at 3 months after hospital discharge had a direct effect (b = 0.678, p < 0.001) and indirect mediating effect (b = 0.276, p < 0.001) on screening positive for PPTSD. The results provide actionable implications for mental health and NICU providers: (1) routine screening for uncertainty and risk factors including previous personal and family history of mental illness, and (2) the development of NICU follow-up support services to mitigate risk for PPTSD.

OBJECTIVE: To test whether prospective classification of infants with bronchopulmonary dysplasia identifies lower-risk infants for discharge with home oxygen who have fewer rehospitalizations by 1 year after neonatal intensive care unit discharge. STUDY DESIGN: This is a prospective single-center cohort that included infants from 2016 to 2019 with bronchopulmonary dysplasia, defined as receiving respiratory support at 36 weeks of postmenstrual age. "Lower-risk" infants were receiving ≤2 L/min nasal cannula flow, did not have pulmonary hypertension or airway comorbidities, and had blood gas partial pressure of carbon dioxide <70 mm Hg. We compared 3 groups by discharge status: lower-risk room air, lower-risk home oxygen, and higher-risk home oxygen. The primary outcome was rehospitalization at 1 year postdischarge, and the secondary outcomes were determined by the chart review and parent questionnaire. RESULTS: Among 145 infants, 32 (22%) were lower-risk discharged in room air, 49 (32%) were lower-risk using home oxygen, and 64 (44%) were higher-risk. Lower-risk infants using home oxygen had rehospitalization rates similar to those of lower-risk infants on room air (18% vs 16%, P = .75) and lower rates than higher-risk infants (39%, P = .018). Lower-risk infants using home oxygen had more specialty visits (median 10, IQR 7-14 vs median 6, IQR 3-11, P = .028) than those on room air. Classification tree analysis identified risk status as significantly associated with rehospitalization, along with distance from home to hospital, inborn, parent-reported race, and siblings in the home. CONCLUSIONS: Prospectively identified lower-risk infants discharged with home oxygen had fewer rehospitalizations than higher-risk infants and used more specialty care than lower-risk infants discharged in room air.

OBJECTIVE: To describe characteristics, outcomes, and risk factors for death or tracheostomy with home mechanical ventilation in full-term infants with chronic lung disease (CLD) admitted to regional neonatal intensive care units. STUDY DESIGN: This was a multicenter, retrospective cohort study of infants born ≥37 weeks of gestation in the Children's Hospitals Neonatal Consortium. RESULTS: Out of 67,367 full-term infants admitted in 2010-2016, 4886 (7%) had CLD based on receiving respiratory support at either 28 days of life or discharge. 3286 (67%) were still hospitalized at 28 days receiving respiratory support, with higher mortality risk than those without CLD (10% vs. 2%, p < 0.001). A higher proportion received tracheostomy (13% vs. 0.3% vs. 0.4%, p < 0.001) and gastrostomy (30% vs. 1.7% vs. 3.7%, p < 0.001) compared to infants with CLD discharged home before 28 days and infants without CLD, respectively. The diagnoses and surgical procedures differed significantly between the two CLD subgroups. Small for gestational age, congenital pulmonary, airway, and cardiac anomalies and bloodstream infections were more common among infants with CLD who died or required tracheostomy with home ventilation (p < 0.001). Invasive ventilation at 28 days was independently associated with death or tracheostomy and home mechanical ventilation (odds ratio 7.6, 95% confidence interval 5.9-9.6, p < 0.0001). CONCLUSION: Full-term infants with CLD are at increased risk for morbidity and mortality. We propose a severity-based classification for CLD in full-term infants. Future work to validate this classification and its association with early childhood outcomes is necessary.
