Long-term respiratory and developmental outcomes in children with bronchopulmonary dysplasia and history of tracheostomy.
Ontology highlight
ABSTRACT: Objective
The long-term morbidity among children with severe bronchopulmonary dysplasia who require tracheostomy (tBPD) relative to those without tracheostomy (sBPD) is not well characterized. We compared childhood lung function and neurodevelopmental outcomes in tBPD and sBPD.Study design
Retrospective case-control study of N = 49 tBPD and N = 280 sBPD subjects in Boston Children's Hospital Preterm Lung Patient Registry and medical record. We compared NICU course, childhood spirometry, and neurodevelopmental testing.Result
tBPD subjects were more likely than sBPD to be Black, have pulmonary hypertension, and have subglottic stenosis. tBPD subjects had lower maximal childhood FEV1 % predicted (β = -0.14) and FEV1/FVC (β = -0.08); spirometry curves were more likely to suggest fixed extrathoracic obstruction. tBPD subjects had greater cognitive and motor delays <24 months, and greater cognitive delays >24 months.Conclusion
Compared to subjects with sBPD who did not require tracheostomy, tBPD subjects suffer from increased long-term impairment in respiratory function and neurodevelopment.

Project description:Objectives: To examine the importance of perinatal and postnatal environmental factors on developmental and respiratory outcomes among preterm infants with bronchopulmonary dysplasia (BPD). Methods: Preterm infants (<32 weeks of gestation) born at a single tertiary medical center between 2012 and 2015 were included. Development was assessed at 12 months corrected age. Parents retrospectively completed a health and lifestyle questionnaire reviewing their child's health during the first 2 years of life. A linear regression model was applied to assess the effect of various perinatal and postnatal factors on development. A machine-learning algorithm was trained to assess factors affecting inhaler use. Results: Of 398 infants meeting the inclusion criteria, 208 qualified for the study: 152 (73.1%) with no BPD, 40 (19.2%) with mild BPD, and 16 (7.7%) with moderate-severe BPD. Those in the moderate-severe group were more likely to be male, have mothers who were less educated, and require longer ventilation periods and less time to regain birth weight. They were also more likely to have mothers with asthma/allergies and to have a parent who smoked. Those in the moderate-severe BPD group exhibited significantly lower developmental scores (85.2 ± 16.4) than the no-BPD group (99.3 ± 10.9) and the mild BPD group (97.8 ± 11.7, p < 0.008) as well as more frequent inhaler use (p = 0.0014) than those with no or mild BPD. In addition to perinatal factors, exposure to breast milk, income level and daycare attendance positively affected development. Exposure to cigarette smoke, allergies among family members and daycare attendance proved to be important factors in inhaler use frequency. Conclusions: Postnatal environmental factors are important in predicting and modifying early childhood outcomes among preterm infants.

Project description:ObjectivesWe sought to investigate how race, ethnicity, and socioeconomic status relate to tracheostomy insertion and post-tracheostomy mortality among infants with bronchopulmonary dysplasia (BPD).MethodsThe Vizient Clinical Database/Resource Manager was queried to identify infants born ≤32 weeks with BPD admitted to US hospitals from January 2012 to December 2020. Markers of socioeconomic status were linked to patient records from the Agency for Healthcare Research and Quality's Social Determinants of Health Database. Regression models were used to assess trends in annual tracheostomy insertion rate and odds of tracheostomy insertion and post-tracheostomy mortality, adjusting for sociodemographic and clinical factors.ResultsThere were 40,021 ex-premature infants included in the study, 1614 (4.0%) of whom received a tracheostomy. Tracheostomy insertion increased from 2012 to 2017 (3.1%-4.1%), but decreased from 2018 to 2020 (3.3%-1.6%). Non-Hispanic Black infants demonstrated a 25% higher odds (aOR 1.25, 1.09-1.43) and Hispanic infants demonstrated a 20% lower odds (aOR 0.80, 0.65-0.96) of tracheostomy insertion compared with non-Hispanic White infants. Patients receiving public insurance had increased odds of tracheostomy insertion (aOR 1.15, 1.03-1.30), but there was no relation between other metrics of socioeconomic status and tracheostomy insertion within our cohort. In-hospital mortality among the tracheostomy-dependent was 14.1% and was not associated with sociodemographic factors.ConclusionsDisparities in tracheostomy insertion are not accounted for by differences in socioeconomic status or the presence of additional neonatal morbidities. Post-tracheostomy mortality does not demonstrate the same relationships. Further investigation is needed to explore the source and potential mitigators of the identified disparities.

Project description:New definitions for bronchopulmonary dysplasia (BPD) have recently been suggested, and an accurate diagnosis, including severity classification with proper definition, is crucial to identify high-risk infants for appropriate interventions. To determine whether recently suggested BPD definitions can better predict long-term outcomes of BPD in extremely preterm infants (EPIs) than the original BPD definition, BPD was classified with severity 1, 2, and 3 using three different definitions: definition A (original), National Institute of Child Health and Human Development (NICHD) definition in 2001; definition B, the modified NICHD 2016 definition (graded by the oxygen concentration and the respiratory support at 36 weeks' postmenstrual age [PMA]); and definition C, the modified Jensen 2019 definition (graded by the respiratory support at 36 weeks' PMA). We evaluated 1050 EPIs using a national cohort. Whereas EPIs with grade 2 or 3 BPD as per definition A did not show any increase in the risk, EPIs with BPD diagnosed by definition B and C showed significantly increased risk for poor outcomes, such as respiratory mortality and morbidities, neurodevelopmental delay, and growth restriction at 18-24 months of corrected age. The recently suggested definition and severity grading better reflects long-term childhood morbidities than the original definition in EPIs.

Project description:ObjectiveLong-term respiratory consequences of bronchopulmonary dysplasia (BPD) in preterm infants born in the post-surfactant era ("new" BPD) remain partially unknown. The present study aimed to evaluate the respiratory outcomes of "new" BPD in adolescents who were born preterm.MethodsThis multicenter, cross-sectional study included 286 adolescents born between 2003 and 2005 (mean age: 14.2 years); among them, 184 and 102 were born extremely preterm (EP; <28 weeks' gestation) and moderate-late preterm (32 to <37 weeks' gestation), respectively. Among EP adolescents, 92 had BPD, and 92 did not. All participants underwent lung function tests, skin prick testing, and questionnaires on asthma symptoms and quality of life.ResultsEP adolescents with BPD had significantly lower forced expiratory volume in 1 s (FEV1 ), forced vital capacity (FVC), FEV1 /FVC ratio, and forced expiratory flow between 25% and 75% of FVC than other included adolescents. FEV1 /FVC ratios were below the lower limit of normal (z-score <-1.645) in 30.4% of EP adolescents with BPD, 13.0% of EP adolescents without BPD, and 11.8% of adolescents who were born moderate-late preterm. Bronchodilator response and air-trapping were significantly higher in BPD adolescents than in other adolescents. Diffusion capacity was significantly lower in EP adolescents than in moderate-late preterm adolescents. Asthma symptoms and quality-of-life scores were similar among groups.ConclusionEP adolescents with "new" BPD had poorer pulmonary function than EP adolescents without BPD or moderate-late preterm adolescents. Further studies are needed to determine whether "new" BPD is associated with early-onset chronic obstructive pulmonary disease in adulthood.

Project description:IntroductionSince premature males are more likely to be diagnosed with bronchopulmonary dysplasia we hypothesized that differences in respiratory outcomes after initial hospital discharge and during the first 3 years of life would exist between females and males diagnosed with BPD.MethodsSubjects with the diagnosis of BPD were recruited from the Johns Hopkins Bronchopulmonary Dysplasia Clinic between 2008 and 2014. Clinical features were assessed through chart review (n = 482). Respiratory morbidities were assessed by caregiver questionnaires at clinic visits (n = 429), including emergency department visits, hospital admissions, systemic steroid use, and antibiotic use for respiratory reasons since the last BPD clinic visit or after initial hospital discharge if assessed at the first visit.ResultsMale infants weighed significantly more at birth, had higher birth weight percentiles and were more likely to be non-white compared to female infants. The frequency of ever acute care use was 36.9% for emergency department visits, 27.4% for hospital admissions, 36.9% for systemic steroid use, and 40.5% for antibiotic use for a respiratory illness. No differences in respiratory morbidities were found between males and females. Females however, tended to be weaned from supplemental oxygen over 3 months later than males.ConclusionsCompared to females with BPD, males were more likely to weigh more, have higher birth weight percentiles and be non-white. After initial hospital discharge, there were no difference in respiratory morbidities between males and females with BPD. Female infants however were more likely to be weaned from supplemental oxygen at a later age than male infants. Pediatr Pulmonol. 2017;52:217-224. © 2016 Wiley Periodicals, Inc.

Project description:BackgroundThe decision to pursue chronic mechanical ventilation involves a complex mix of clinical and social considerations. Understanding the medical indications to pursue tracheostomy would reduce the ambiguity for both providers and families and facilitate focus on appropriate clinical goals.ObjectiveTo describe potential indications to pursue tracheostomy and chronic mechanical ventilation in infants with severe BPD (sBPD).Study designWe surveyed centers participating in the Children's Hospitals Neonatal Consortium to describe their approach to proceed with tracheostomy in infants with sBPD. We requested a single representative response per institution. Question types were fixed form and free text responses.ResultsThe response rate was high (31/34, 91%). Tracheostomy was strongly considered when: airway malacia was present, PCO2 ≥ 76-85 mmHg, FiO2 ≥ 0.60, PEEP ≥ 9-11 cm H2O, respiratory rate ≥ 61-70 breaths/min, PMA ≥ 44 weeks, and weight <10th %ile at 44 weeks PMA.ConclusionsUnderstanding the range of indications utilized by high level NICUs around the country to pursue a tracheostomy in an infant with sBPD is one step toward standardizing consensus indications for tracheostomy in the future.

Project description:BackgroundBronchopulmonary dysplasia (BPD) is a risk factor for respiratory disease in adulthood. Despite the differences in underlying pathology, patients with a history of BPD are often treated as asthmatics. We hypothesized that pulmonary outcomes and health-related quality of life (HRQoL) were different in adults born preterm with and without a history of BPD compared to asthmatics and healthy individuals.MethodsWe evaluated 96 young adults from the LUNAPRE cohort ( clinicaltrials.gov/ct2/show/NCT02923648 ), including 26 individuals born preterm with a history of BPD (BPD), 23 born preterm without BPD (preterm), 23 asthmatics and 24 healthy controls. Extensive lung function testing and HRQoL were assessed.ResultsThe BPD group had more severe airway obstruction compared to the preterm-, (FEV1- 0.94 vs. 0.28 z-scores; p ≤ 0.001); asthmatic- (0.14 z-scores, p ≤ 0.01) and healthy groups (0.78 z-scores, p ≤ 0.001). Further, they had increased ventilation inhomogeneity compared to the preterm- (LCI 6.97 vs. 6.73, p ≤ 0.05), asthmatic- (6.75, p = 0.05) and healthy groups (6.50 p ≤ 0.001). Both preterm groups had lower DLCO compared to healthy controls (p ≤ 0.001 for both). HRQoL showed less physical but more psychological symptoms in the BPD group compared to asthmatics.ConclusionsLung function impairment and HRQoL in adults with a history of BPD differed from that in asthmatics highlighting the need for objective assessment of lung health.

Project description:Unlike other complications among very low birth weight infants (VLBW), the incidence of bronchopulmonary dysplasia (BPD) has not decreased substantially, partly because of the different definitions of BPD applied by different researchers. In this retrospective cohort study, we aimed to compare the 2018 revised definition and the 2001 consensus definition of BPD proposed by the National Institute of Child Health and Human Development (NICHD), as well as to identify which definition better predicts severe respiratory morbidities or death. We included 417 infants born at a gestational age <32 weeks and classified them as having BPD or without BPD based on the two definitions, with a final follow-up at 18-24 months. We performed between-group comparisons of death and respiratory outcomes. Statistical analyses were performed using descriptive statistics, comparative tests, and receiver operating characteristic curves. The mean ± standard deviation gestational age and birth weight of the 417 eligible infants were 29.1 ± 1.4 weeks and 1186.6 ± 197.8 g, respectively. Among the included infants, five and three infants died before and after 36 weeks of post-menstrual age (PMA), respectively, with 68 and 344 infants evaluated at discharge and 36 weeks' PMA, respectively. We diagnosed 163 (39.1%) and 70 (16.8%) infants with BPD according to the 2001 and 2018 NICHD definitions, respectively. The 2001 NICHD definition displayed a higher sensitivity (0.60 vs. 0.28), better negative predictive value (0.89 vs. 0.85), and larger area under the receiver operating characteristic curve (0.66 vs. 0.57), but a lower specificity (0.65 vs. 0.87) and worse positive predictive value (0.26 vs. 0.31), than the 2018 definition for serious respiratory morbidity or mortality at a corrected age of 18-24 months. Compared with the 2018 NICHD definition of BPD, the 2001 NICHD consensus definition may result in more cases of false-positive or unclassified severity. However, it may be a better indicator of severe respiratory morbidities or death during the first 18-24 months. Nevertheless, there is a need for future studies to assess the validity of the new diagnostic criteria.

Project description:BackgroundTobacco smoke exposure (TSE) may increase respiratory morbidities in young children with bronchopulmonary dysplasia (BPD). Rapid respiratory rates, close proximity to a smoking caregiver, and increased dermal absorption of tobacco smoke components can contribute to systemic exposure. In this study, hair nicotine levels were used as a biomarker of chronic TSE in young children with BPD to determine if hair nicotine levels correlate with caregiver self-report of TSE and respiratory morbidities.MethodsFrom 2012 to 2014, hair nicotine levels were measured from consecutive children seen in a BPD outpatient clinic and compared with caregiver questionnaires on household smoking. The relationship between respiratory morbidities and self-reported TSE or hair nicotine level was assessed.ResultsThe mean hair nicotine level from 117 children was 3.1 ± 13.2 ng/mg. Hair nicotine levels were significantly higher in children from smoking households by caregiver self-report compared with caregivers who reported no smoking (8.2 ± 19.7 ng/mg vs 1.8 ± 10.7; P < .001). In households that reported smoking, hair nicotine levels were higher in children with a primary caregiver who smoked compared with a primary caregiver who did not smoke. Among children with BPD who required respiratory support (n = 50), a significant association was found between higher log hair nicotine levels and increased hospitalizations and limitation of activity.ConclusionsChronic TSE is common in children with BPD, with hair nicotine levels being more likely to detect TSE than caregiver self-report. Hair nicotine levels were also a better predictor of hospitalization and activity limitation in children with BPD who required respiratory support at outpatient presentation.

Project description:Identify hospital-level care variations and association with length of stay (LOS) and hospital revisit in children with tracheostomies hospitalized for bacterial respiratory tract infections (bRTIs).A multicenter, retrospective cohort study that used the Pediatric Health Information System database between 2007 and 2014 of patients with tracheostomies aged ?18 years with a primary diagnosis of bRTI (eg, tracheitis) or a primary diagnosis of a bRTI symptom (eg, cough) and a secondary diagnosis of bRTI. Primary outcomes were LOS and 30-day all-cause revisit rates. Secondary outcomes included hospital-level diagnostic testing and anti-Pseudomonas antibiotic use. We used mixed-effects negative binomial (for LOS) and logistic (for revisit) regression to explore the relationship between hospital-level diagnostic test utilization and the outcomes.Data representing 4137 unique patients with a median age of 3 years (interquartile range: 1-9 years) were included. Median LOS was 4 days (interquartile range: 3-8 days), and the 30-day revisit rate was 24.9%. Use of diagnostic testing and empirical anti-Pseudomonas antibiotics varied significantly among hospitals (all P values <.001). After adjusting for patient and hospital characteristics, compared with low test utilization hospitals, there were no differences in 30-day all-cause revisit rates in moderate (adjusted odds ratio: 1.19; 95% confidence interval [CI]: 0.93-1.52) or high (adjusted odds ratio: 1.07; 95% CI: 0.82-1.39) utilization hospitals. LOS in hospitals with moderate (% difference: -0.8%; 95% CI: -14.4-14.9%) or high (% difference: 13.9%; 95% CI: -0.7-30.6%) test utilization was not significantly longer.Given that care variations were not associated with outcomes, future research should focus on standardizing diagnosis and treatment of bRTIs and readmission prevention in this population.
