Weaning Strategy of Diuretics in Outpatient Preterm Infants with Bronchopulmonary Dysplasia: A National Survey

Objective Long-term diuretic treatment in patients with bronchopulmonary dysplasia (BPD) is common despite lack of data that support its use. We aimed to characterize the commonly used diuretics weaning strategies for outpatient clinically stable preterm infants with BPD. Study Design We conducted a cross-sectional web-based survey among all pediatric pulmonologists and neonatologists in Israel. Questionnaire included data regarding practitioners' different diuretics-weaning practice in this population. Results The response rate for pulmonologists and neonatologists were 35/50 (70%) and 36/120 (30%), respectively. When both oxygen and diuretics are used, 59% wean oxygen first and 32% wean diuretics first. If patients are solely on diuretics, 27% discontinue instantly, 34% decrease the dosage gradually, and 34% outgrow the discharge dosage. Significantly more pulmonologists decrease the dosage gradually, while more neonatologists discontinue at once (p < 0.001). Most participants (94%) reported being unsatisfied with the existing data and guidelines regarding these issues. Conclusion Our results showed a wide range of practice patterns in the weaning strategy of diuretics in outpatient preterm infants with BPD. Pulmonologists and neonatologists differ significantly in their weaning strategy. A prospective larger controlled study to explore the outcome of gradual tapering versus discontinuation without weaning is warranted.
