Home oxygen use and 1-year outcome among preterm infants with bronchopulmonary dysplasia discharged from a Chinese regional NICU

Family Integrated Care Shortens the Duration of Home Oxygen Therapy in Infants With Bronchopulmonary Dysplasia

BACKGROUND

There have been few reports on whether family integrated care (FIC) can help premature infants with moderate to severe bronchopulmonary dysplasia (BPD) to shorten the duration of home oxygen therapy (HOT).

PURPOSE

To investigate the effect of FIC on the duration of HOT in premature infants with moderate to severe BPD.

METHODS

The subjects were retrospectively selected from premature infants with moderate to severe BPD in our center between June 2019 and December 2021. Patients were divided into the FIC group (n = 47) and the non-FIC group (n = 34). For univariate analysis, t test, Mann-Whitney U test, Pearson χ 2 test, or Fisher exact test was performed to explore the differences between the 2 groups. For multivariate analysis, simple and multiple linear regression was conducted to explore the effect of FIC on the duration of HOT.

RESULTS

(1) The duration of HOT and length of stay after grouping were significantly shorter in the FIC group than in the non-FIC group ( P < .05). (2) The results of linear regression further revealed that FIC could significantly shorten the duration of HOT (simple linear regression, FIC [A] B : -12.709, 95% confidence interval (CI): -21.665 to -3.753; multiple linear regression, FIC [B] B : -11.419, 95% CI: -18.055 to -4.783).

IMPLICATIONS FOR PRACTICE AND RESEARCH

FIC improved the optimal target oxygen saturation ratio before discharge and shortened the duration of HOT in premature infants with moderate and severe BPD. FIC should be promoted in China's neonatal intensive care units, though it puts forward new requirements for nursing education and training.

Types of home respiratory support in children with bronchopulmonary dysplasia and factors determining its duration: A scoping review

Bronchopulmonary dysplasia also known as chronic lung disease of prematurity has changed as a disease entity over the last five decades and children with "new bronchopulmonary dysplasia (BPD)" have better survival rates. This necessitates strategies to prevent severe BPD and provide organized home support. Home respiratory support in these children varies from home oxygen to noninvasive ventilation and tracheostomy ventilation. This review was conducted utilizing Joanna Briggs Institute publications on evidence synthesis and presentation of results for a scoping review. The Preferred Reporting Items for Systematic Review and Meta-Analyses were used to report the results. The risk of bias assessment was done using "The Cochrane Handbook for Systematic Reviews tool for interventional studies." After screening for the duplication of results and applying inclusion and exclusion criteria, twenty-seven studies were assessed by reading the full texts. Out of these, eleven were finally included in this systematic review. The total sample size from all studies was 4794, including 2705 males. The 4/11 studies home oxygen, one study reported continuous positive airway pressure/bilevel positive airway pressure and seven studies used tracheostomy or tracheostomy ventilation. The median duration of post-natal invasive ventilation was higher in those discharged on home oxygen compared to those who did not need oxygen at discharge. There is a significant proportion of children who are tracheostomy ventilated (8.65%) at home. In the absence of established guidelines, these children are vulnerable when it comes to care at home and the timing of decannulation. For home oxygen alone, guidelines by ERS, ATS and BTS have streamlined weaning protocols and the need for having a multi-disciplinary team to care for these children.

Outpatient respiratory outcomes in children with BPD on supplemental oxygen

INTRODUCTION

Preterm children with bronchopulmonary dysplasia (BPD) frequently require supplemental oxygen in the outpatient setting. In this study, we sought to determine patient characteristics and demographics associated with need for supplemental oxygen at initial hospital discharge, timing to supplemental oxygen liberation, and associations between level of supplemental oxygen and likelihood of respiratory symptoms and acute care usage in the outpatient setting.

METHODS

A retrospective analysis of subjects with BPD on supplemental oxygen (O2 ) was performed. Subjects were recruited from outpatient clinics at Johns Hopkins University and the Children's Hospital of Philadelphia between 2008 and 2021. Data were obtained by chart review and caregiver questionnaires.

RESULTS

Children with BPD receiving ≥1 L of O2 were more likely to have severe BPD, pulmonary hypertension, and be older at initial hospital discharge. Children discharged on higher levels of supplemental O2 were slower to wean to room air compared to lower O2 groups (p < 0.001). Additionally, weaning off supplemental O2 in the outpatient setting was delayed in children with gastrostomy tubes and those prescribed inhaled corticosteroids, on public insurance or with lower household incomes. Level of supplemental O2 at discharge did not influence outpatient acute care usage or respiratory symptoms.

CONCLUSION

BPD severity and level of supplemental oxygen use at discharge did not correlate with subsequent acute care usage or respiratory symptoms in children with BPD. Weaning of O2 however was significantly associated with socioeconomic status and respiratory medication use, contributing to the variability in O2 weaning in the outpatient setting.
