[Bronchopulmonary dysplasia: definitions and classifications]

Area of Science:

• Neonatology
• Pediatric Pulmonology
• Perinatal Medicine

Context:

• Bronchopulmonary dysplasia (BPD) is a prevalent complication in very low birth weight (VLBW) infants, particularly those of extremely low birth weight (ELBW).
• Despite advancements in respiratory distress syndrome (RDS) management, BPD incidence has not decreased in this vulnerable population, though its clinical presentation has evolved.
• Significant inter-center variability exists in BPD frequency, likely stemming from inconsistent diagnostic criteria.

Purpose:

• To review and standardize the current diagnostic criteria for bronchopulmonary dysplasia (BPD).
• To minimize inter-center discrepancies in BPD diagnosis and reporting.
• To provide a unified standard for the Spanish Society of Neonatology.

Summary:

• Bronchopulmonary dysplasia (BPD) is the most common sequela in very low birth weight infants.
• Current diagnostic criteria for BPD lack uniformity, leading to variations in reported incidence across healthcare facilities.
• This article proposes a standardized approach to BPD diagnosis to ensure consistency.

Impact:

• Aims to reduce inter-center differences in bronchopulmonary dysplasia diagnosis.
• Facilitates more accurate epidemiological studies on BPD.
• Promotes consistent clinical management and research for premature infants affected by BPD.
