{Abstract}: <B>BACKGROUND: </B>There is uncertainty and lack of consensus regarding optimal management of patent ductus arteriosus (PDA). We aimed to determine current clinical practice in PDA management across a range of different regions internationally.<BR><B>METHODS: </B>We surveyed PDA management practices in neonatal intensive care units using a pre-piloted web-based survey, which was distributed to perinatal societies in 31 countries. The survey was available online from March 2018 to March 2019.<BR><B>RESULTS: </B>There were 812 responses. The majority of clinicians (54%) did not have institutional protocols for PDA treatment, and 42% reported variable management within their own unit. Among infants &lt;28 weeks (or &lt;1,000 g), most clinicians (60%) treat symptomatically. Respondents in Australasia were more likely to treat PDA pre-symptomatically (44% vs. 18% all countries [OR 4.1; 95% CI 2.6-6.5; p &lt; 0.001]), and respondents from North America were more likely to treat symptomatic PDA (67% vs. 60% all countries [OR 2.0; 95% CI 1.5-2.6; p &lt; 0.001]). In infants ≥28 weeks (or ≥1,000 g), most clinicians (54%) treat symptomatically. Respondents in North America were more likely to treat PDAs in this group of infants conservatively (47% vs. 38% all countries [OR 2.3; 95% CI 1.7-3.2; p &lt; 0.001]), and respondents from Asia were more likely to treat the PDA pre-symptomatically (21% vs. 7% all countries [OR 5.5; 95% CI 3.2-9.8; p &lt; 0.001]).<BR><B>CONCLUSIONS: </B>There were marked international differences in clinical practice, highlighting ongoing uncertainty and a lack of consensus regarding PDA management. An international conglomeration to coordinate research that prioritises and addresses these areas of contention is indicated.
