Background Central venous catheters (CVC) are essential in medicine for monitoring, drug and fluid administration, and renal replacement therapy. Complications such as arrhythmias, endothelial damage, thrombosis, or hemothorax might arise from incorrect positioning. Despite evidence showing their reduction using ultrasound to guide insertion and correct tip positioning, and greater accuracy for tip position assessment vs. chest-X-ray (CXR), ultrasound adoption greatly varies worldwide. This study, conducted by the World Interactive Network Focused On Critical Ultrasound (WINFOCUS) aimed to assess global practices in CVC insertion and tip position confirmation. Methods A web-based survey was conducted (April–September 2023) among WINFOCUS members/affiliates across five continents. It assessed clinical backgrounds, CVC insertion and tip position check methods, and reasons for not using ultrasound. Developed by WINFOCUS Research sub-committee, the survey was emailed, with two reminders. Data were analyzed using SPSS 27.0. Results A total of 1,227 respondents (5.1% response rate) participated, mainly from Europe (33.5%), Asia (28.3%), and the Americas (30.9%), with 95.4% being physicians. Over half (51.3%) had over six years of experience and placed over 200 CVC, mostly using ultrasound guidance (70% of cases). The internal jugular vein (IJV) was the preferred insertion site (74%). Ultrasound was used for pre-insertion assessment (55%) and vessel puncture (57%) but less for guidewire confirmation (44%). CXR remained the primary method for tip position assessment (52%), while only 12% relied solely on bedside ultrasound. Barriers to exclusive ultrasound use included institutional guidelines (33.9%) and medico-legal concerns (13.8%). Conclusions Despite evidence favoring ultrasound for CVC insertion and tip position confirmation, its use remains inconsistent, with CXR still widely used. This survey underscores the need for standardized protocols and training to enhance US adoption, improve patient safety, and reduce CXR reliance.
