Abstract

OBJECTIVE:

To investigate the relationship between the severity-based definition of bronchopulmonary dysplasia (BPD), choice of treatment, and neurocognitive outcomes at age 3 and 8 years.

DESIGN:

This is a secondary analysis of data collected from a prospective, longitudinal sample of 99 children with a history of BPD.

SETTING:

Children born with BPD admitted to 3 hospitals from February 1, 1989, to November 31, 1991.

PARTICIPANTS:

Ninety-nine children with BPD were longitudinally assessed at age 3 and 8 years. Three severity groups (mild, moderate, and severe) were formed based on gestational age and need for supplemental oxygen therapy.

MAIN EXPOSURES:

Supplemental oxygen therapy for 28 days or longer, birth weight less than 1500 g, and radiographic evidence of lung disease.

MAIN OUTCOME MEASURES:

Neurologic and medical outcomes; type of medical management; and language, achievement, and cognitive functioning were compared among the 3 severity groups.

RESULTS:

Severity classification of BPD was associated with poorer outcomes. Compared with children with mild or moderate BPD, children with severe BPD performed more poorly on IQ tests (Mental Development Index, 90 vs 76.4; and Psychomotor Development Index, 92.5 vs 73.9) and language measures (total, 95 vs 82) at age 3 years and performance IQ (86 vs 75) and perceptual organization (86 vs 76) at age 8 years. Severity of BPD was not associated with choice of medical management but was related to educational interventions. Children with severe BPD received more special education services (69% vs 44%) than did children with mild BPD.

CONCLUSIONS:

The severity-based classification clarifies the relationship between BPD and developmental sequelae. Children with severe BPD required more interventions at age 8 years than did children with mild or moderate BPD.
