Understanding the short and long-term pulmonary and neurologic outcomes of neonates with bronchopulmonary dysplasia (BPD) is important in neonatal care for low-birth-weight infants. Different criteria for BPD may have different associations with long-term outcomes. Currently, two criteria for diagnosing BPD have been proposed by the NIH (2001) and NRN (2019) for preterm infants at a postmenstrual age (PMA) of 36 weeks. We investigated which BPD definition best predicts long-term outcomes. Korean nationwide data for preterm infants born between 24 +0 and < 32 +0 weeks gestation from were collected. For long-term outcomes, severity based on the NRN criteria was significantly related to neurodevelopmental impairment (NDI) in a univariate analysis after other risk factors were controlled. For the admission rate for respiratory disorder, grade 3 BPD of the NRN criteria had the highest specificity (96%), negative predictive value (86%), and accuracy (83%). For predicting NDI at the 18–24 month follow-up, grade 3 BPD of the NRN criteria had the best specificity (98%), positive (64%) and negative (79%) predictive values, and accuracy (78%) while NIH severe BPD had the highest sensitivity (60%). The NRN definition was more strongly associated with poor 2-year developmental outcomes. BPD diagnosed by NRN definitions might better identify infants at high risk for NDI.
Inclusion
Bronchopulmonary dysplasia (BPD) https://datingranking.net/plenty-of-fish-review/ was a primary side-effect inside suprisingly low delivery pounds kids (VLBWIs). Much more serious BPD try of the a greater odds of developmental handicap and you may reduced pulmonary mode step one,2,3 . The course of the disease, such as the significance of rehospitalization and neurodevelopmental handicap, is actually a reported concern among moms and dads and medical care team 4 . Finding out how state seriousness try of developmental delay and you may readmissions will help book future research and you may top quality improvement effort to reduce the responsibility on the problems.
BPD was first laid out from the Northway mais aussi al. 5 over 50 years before; yet not, inside the 2001, brand new Federal Institute out of Kid Health (NIH) changed the fresh new categorical definitions out of BPD. Recently, inter-center variability during the outdoors government and nasal cannula flow, as well as the use of noninvasive ventilation, can prejudice the new NIH category regarding BPD presence and you may severity. To phrase it differently, these commonly used requirements might not be acceptable for the present day logical situation or the prediction out of much time-title outcomes of modern VLBWIs 6,7 . According to that it difference, Jensen ainsi que al. 8 suggested a different concept of BPD one to ideal predicted early teens morbidity and categorized state severity depending on the form from breathing support, whatever the use of supplemental fresh air. Which definition is actually changed so you’re able to a whole lot more truthfully predict respiratory readmission and developmental delays when you look at the an effective U.S.-born society.
Hence, we lined up to decide and this definition of BPD at an effective PMA from 36 days are most suitable to possess anticipating a lot of time-label neonatal outcomes, including pulmonary and you can neurological effects, measured at the 18–a couple of years corrected many years (CA), from inside the good multicenter cohort study of VLBWIs in line with the nationwide Korean Neonatal Circle (KNN) registry.

A total of 8294 babies created ranging from 24 +0 months and you can 29 +six weeks GA was in fact entered for the KNN, After excluding kids, 2889 VLBWIs stayed; one of them, 1849 (64.0%) got done follow-upwards advice offered at Ca 18–a couple of years, as well as breathing readmission and you can developmental consequences (Fig. 1). Of these 1849 VLBWIs, 1221 (66.0%) got BPD according to NIH definition, and 665 children (36%) that have mild BPD, 184 children (10%) having moderate BPD, and 372 children (19%) which have severe BPD. However 555 babies (30%) had BPD according to the NRN definition, along with 186 children (10%) which have amount step one BPD, 303 kids (16%) that have levels 2 BPD, and you can 66 infants (4%) which have stages step three BPD (Dining table step 1).
