Neonatal BPD Outcome Estimator
Background Information
Data from the NICHD Neonatal Research Network were used to develop a web-based BPD estimator that accurately predicts the risk of bronchopulmonary dysplasia (BPD)-defined according to the Eunice Kennedy Shriver National Institute of Child Health and Human Development consensus definition of no, mild, moderate, and severe BPD (Jobe 2001) - as well as the competing outcome of death, by postnatal day. The population includes infants 23-30 weeks gestation and 501-1250 grams birth weight. The full article can be found here:

Certain combinations of gestational age (GA) and birth weight (BW) occurred rarely in the data used to derive the model; therefore we have chosen not to provide estimates for these outlying pairs.  These combinations are: GA=23 & BW >=750g; GA=24 & BW >=950g; GA=25 & BW >=1150g; GA=26 & BW >=1200g; GA=29 & BW <=649g; and, GA=30 & BW <=699g.
