Pulmonary hypertension in infants with bronchopulmonary dysplasia: risk factors, mortality and duration of hospitalisation
JOURNAL OF PERINATAL MEDICINE(2022)
摘要
Objectives Pulmonary hypertension (PH) is a complication of bronchopulmonary dysplasia (BPD) and associated with increased mortality and morbidity. Our aim was to identify, in infants with BPD, the effect of PH on health-care utilisation and health related cost of care. Methods An electronic data recording system was used to identify infants <= 32 weeks of gestation who developed BPD. PH was classified as early (<= 28 days after birth) or late (>28 days after birth). Results In the study period, 182 infants developed BPD; 22 (12.1%) developed late PH. Development of late PH was associated with a lower gestational age [24.6 (23.9-26.9) weeks, p=0.001] and a greater need for positive pressure ventilation on day 28 after birth (100%) compared to infants without late PH (51.9%) (odds ratio (OR) 19.5, 95% CI: 2.6-148), p<0.001. Late PH was associated with increased mortality (36.4%) compared those who did not develop late PH (1.9%) after adjusting for gestational age and ventilation duration (OR: 26.9, 95% CI: 3.8-189.4), p<0.001. In infants who survived to discharge, late PH development was associated with a prolonged duration of stay [147 (118-189) days] compared to the infants that did not develop late PH [109 (85-149) days] (p=0.03 after adjusting for gestational age). Infants who had late PH had a higher cost of stay compared to infants with BPD who did not develop late PH (median 113,494 pound vs. 78,677 pound, p=0.016 after adjusting for gestational age). Conclusions Development of late PH was associated with increased mortality, a prolonged duration of stay and higher healthcare cost.
