Position assessment is routinely done by radiography. The objective of this study is to characterize neonatal catheter and tube placement in terms of the proportion of those devices that are malpositioned.<\/jats:p><jats:p>\n            Study Design\u2003Using an institutional dataset of 723 chest\/abdominal radiographs of neonatal intensive care unit (ICU) patients (all within 60 days of birth), we assessed the proportion of catheters that are malpositioned. Many radiographs contained multiple catheter types. Umbilical venous catheters (UVCs; 448 radiographs), umbilical arterial catheters (UACs; 259 radiographs), endotracheal tubes (ETTs; 451 radiographs), and nasogastric tubes (NGTs; 603 radiographs) were included in our analysis.<\/jats:p><jats:p>\n            Results\u2003UVCs were malpositioned in 90% of radiographs, while UACs were malpositioned in 36%, ETTs in 30%, and NGTs in just 5%. The most common locations in which UVCs were malpositioned were in the right atrium (31%) and umbilical vein (21%), and for UACs the most common malpositioned tip location was the aortic arch (8%). For the remaining tubes, 5% of ETTs were found to be in the right main bronchus and 4% of NGTs were found in the esophagus.<\/jats:p><jats:p>\n            Conclusion\u2003A substantial proportion of catheters and tubes are malpositioned, suggesting that optimizing methods of catheter placement and assessment ought to be areas of focus for future work.<\/jats:p><jats:p>\n            Key Points\n          <\/jats:p>","DOI":"10.1055\/s-0043-1771051","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T18:08:57Z","timestamp":1690394937000},"page":"e2299-e2306","source":"Crossref","is-referenced-by-count":8,"special_numbering":"S","title":["Neonatal Catheter and Tube Placement and Radiographic Assessment Statistics in Relation to Important Anatomic Landmarks"],"prefix":"10.1055","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2909-5384","authenticated-orcid":false,"given":"Robert D.
