Is chronic lung disease in low birth weight infants preventable? A survey of eight centers
Insights
Chronic lung disease in premature infants varied significantly between hospitals. Columbia University reported the best outcomes, with the lowest incidence of this condition in low birth weight infants.
Area of Science:
- Neonatology
- Pediatric Pulmonology
- Public Health
Background:
- Chronic lung disease (CLD) is a significant concern in prematurely born infants.
- Previous observations suggested institutional variations in CLD incidence.
- Understanding these variations is crucial for improving infant respiratory outcomes.
Purpose of the Study:
- To investigate institutional differences in the incidence of chronic lung disease among premature infants.
- To identify risk factors associated with CLD in this population.
- To compare CLD rates across multiple intensive care nurseries.
Main Methods:
- A survey of 1,625 infants with birth weights between 700 and 1,500 g across eight institutions.
- Inclusion criteria: need for increased inspired oxygen at 28 days of age.
- Multivariate logistic regression analysis to account for birth weight, race, and sex.
Main Results:
- Confirmed risk factors for CLD: low birth weight, white race, and male sex.
- Identified significant institutional variations in CLD incidence, even after adjusting for key risk factors.
- Columbia University demonstrated superior outcomes with the lowest CLD incidence among participating centers.
Conclusions:
- Institutional factors significantly influence the incidence of chronic lung disease in premature infants.
- Columbia University's intensive care nursery achieved exceptional results in managing low birth weight infants and preventing CLD.
- Further research into best practices at high-performing institutions is warranted to reduce CLD rates nationwide.
Abstract:
Chronic lung disease in prematurely born infants, defined as the need for increased inspired oxygen at 28 days of age, was thought to be more common in some institutions than in others. To test this hypothesis, we surveyed the experience in the intensive care nurseries at Columbia and Vanderbilt Universities, the Universities of Texas at Dallas, Washington at Seattle, and California at San Francisco, the Brigham and Women's Hospital in Boston, Texas Children's Hospital in Houston, and Mt Sinai Hospital in Toronto. The survey included 1,625 infants with birth weights of 700 to 1,500 g. We confirmed the relationship of risk to low birth weight, white race, and male sex. Significant differences in the incidence of chronic lung disease were found between institutions even when birth weight, race, and sex were taken into consideration through a multivariate logistic regression analysis. Columbia had one of the best outcomes for low birth weight infants and the lowest incidence of chronic lung disease.
