Diagnostic and treatment strategies, however, still lack standardization. By the use of a survey study (PH in BPD), we assessed clinical practice (diagnosis, treatment, follow\u2010up) in preterm infants with early postnatal persistent pulmonary hypertension of the newborn\u00a0(PPHN) as well as at risk for or with established BPD\u2010associated PH between 06\/2018 and 10\/2020 in two\u2010thirds of all German perinatal centers with &gt;70 very low birthweight infants\/year including their cardiology departments and outpatient units. Data were\u00a0analyzed descriptively by measures of locations and distributional shares. In routine postnatal care, clinical presentation and echocardiography were reported as the main diagnostic modalities to screen for PPHN in preterm infants, whereas biomarkers brain natriuretic peptide\/N\u2010terminal pro b\u2010type natriuretic peptide were infrequently used. For PPHN treatment, inhaled nitric oxide\u00a0was used in varying frequency. The majority of participants agreed to prescribe diuretics and steroids (systemic\/inhaled) for infants at risk for or with established BPD\u2010associated PH and strongly agreed on recommending respiratory syncytial virus immunization and the use of home monitoring upon discharge. Reported oxygen saturation targets, however, varied in these patients in in\u2010 and outpatient care. The survey reveals shared practices in diagnostic and therapeutic strategies for preterms with PPHN and BPD\u2010associated PH in Germany. Future studies are needed to agree on detailed echo parameters and biomarkers to diagnose and monitor disease next to a much\u2010needed agreement on the use of pulmonary vasodilators, steroids, and diuretics as well as target oxygen saturation levels.<\/jats:p>","DOI":"10.1002\/pul2.12320","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T05:09:54Z","timestamp":1703221794000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Current
