All four participating neonatal ICU had a comparable number of preterm infants; however, differences were observed in the incidence of treatment (33\u201363%), choice and dosing of medication (ibuprofen or indomethacin), number of pharmacological courses (1\u20134), and the need for surgical ligation after failure of pharmacological treatment (8\u201352%). Despite the differences in treatment, we found no difference in short-term morbidity between the centres. Adjusted mortality showed independent risk contribution of gestational age, birth weight, ductal ligation, and perinatal centre.<\/jats:p><\/jats:sec><jats:sec id=\"S104795111700052X_abs4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>Using benchmarking as a tool identified inter-centre differences. In these four perinatal centres, the factors that explained the differences in patent ductus arteriosus treatment are quite complex.
