Bronchopulmonary dysplasia occurred in 179 infants discharged from a regional neonatal intensive care unit between 1975 and 1982. Perinatal and outcome factors were compared for these study infants and a group of 112 controls matched for birth weight category and year of birth. There were multiple differences between study infants and controls in demographic, diagnostic, and therapeutic items, all of which were categorized as pulmonary items occurring before and after the development of bronchopulmonary dysplasia, and nonpulmonary items. The postdischarge death rate was 11.2% in infants and 0.9% in control infants (P < .001). Ongoing morbidity was most marked in the areas of health history, physical examination, growth, and vision. Neurodevelopmental abnormalities and hearing abnormalities occurred slightly more frequently in study infants than in controls but not significantly so. Major developmental abnormalities were less frequent in this population than has been the case in other follow-up studies in this area. This group of infants requires close postdischarge observation because ongoing morbidity and postdischarge mortality, part of which may be preventable, are frequent.
