Bronchopulmonary dysplasia predictor scale validation in preterm newborns in two neonatal units at 2600 m above sea level.

Introduction: Bronchopulmonary dysplasia (BPD) is common in premature babies. It is difficult to predict the risk of developing this disease and its definition is not well characterized in high altitude cities.

Objective: To determine the operating characteristics of a BPD predictive scale for in preterm infants based on a classical BPD definition and one adjusted for altitude.
