Risk Factors for Neurodevelopmental Impairment at 2- and 5-Years Corrected Age in Preterm Infants with Established Bronchopulmonary Dysplasia.

ABSTRACT:

Introduction

The objective of this study was to identify risk factors for neurodevelopmental impairment (NDI) at 2- and 5-years corrected age (CA) in a cohort of preterm infants with established bronchopulmonary dysplasia (BPD).

Methods

This single-center retrospective cohort study included infants born between 2009 and 2016 at a gestational age (GA) <30 weeks with moderate or severe BPD at 36 weeks' postmenstrual age. Perinatal characteristics, (social) demographics, and comorbidities were collected from the electronic patient records. Odds ratios for NDI were calculated with univariate and multivariate logistic regression analyses adjusting for potential confounders.

Results

Of the 602 eligible infants, 123 infants were diagnosed with BPD. NDI was present in 30.3% and 56.1% at 2- and 5-years CA, respectively. The only independent risk factors associated with NDI in the multivariate analyses were birthweight (adjusted odds ratio [aOR] 0.74, 95% CI 0.57-0.95; aOR 0.70, 95% CI 0.54-0.91, respectively), small for GA (SGA) (aOR 3.25, 95% CI 1.09-9.61; aOR 5.44, 95% CI 1.62-18.2, respectively) at both time points, and male gender at 5-years CA (OR 2.49, 95% CI 1.11-5.57).

Conclusion

Birthweight and SGA are independent risk factors for NDI at 2- and 5-years CA and male gender at 5-years CA in preterm infants with BPD. In contrast, well-known other risk factors for NDI in the general population of preterm infants, such as GA, maternal education, and neonatal comorbidities were not independently associated with NDI.

Project description:Background: Infants born extremely preterm are at high risk of developing bronchopulmonary dysplasia (BPD). This study aimed to assess the incremental health care burden of BPD and associated comorbidities among extremely preterm infants in the United States. Methods: Health service claims in the Premier Perspective database were retrospectively analyzed for infants born at ?28 weeks gestation who were admitted to neonatal intensive care during birth hospitalization and survived to a postmenstrual age of ?36 weeks. Gestational age (GA) at birth and BPD status of infants was determined based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes recorded in the database. Results: Of the 12,017 infants included, 4,904 (40.8%) had BPD. BPD increased with decreasing GA: 67.4% of infants born at <24 weeks GA had BPD vs. 28.7% of those born at 27-28 weeks. Infants with BPD had significantly longer hospital stays following birth than those without (mean [standard deviation (SD)] 102 [34] vs. 83 [24] days, respectively, P < 0.001), and incurred higher total charges (mean [SD] $799,499 [$535,528] vs. $588,949 [$377,137], respectively, P < 0.001). Mean total charges incurred during index hospitalization decreased as GA at birth increased, with GA having a bigger effect than presence or absence of BPD. During their first year, infants with BPD had a higher in-hospital late mortality rate than those without (1.9 vs. 0.6%), and were more likely to have two or more hospital encounters following birth hospitalization (58.0 vs. 48.2%). Among infants who had two or more encounters after discharge, those with BPD experienced a higher percentage of pulmonary symptoms than those without (46.3 vs. 38.9%). Comparison with infants who did not have BPD, retinopathy of prematurity, or intraventricular hemorrhage showed that BPD is the main complication contributing to increased length of stay, costs, in-hospital mortality, and additional health care encounters. Conclusion: BPD is a key contributor to the large health care burden associated with extremely preterm birth. However, GA at birth has a bigger effect on health care costs for extremely preterm infants than the presence of BPD.
