PURPOSE: Millions of central venous catheters (CVCs) are placed annually in the United States for hemodynamic monitoring, delivery of medications, and nutritional support. Real-time ultrasound guidance for insertion of CVCs is recommended by national healthcare organizations and widely accepted as standard of care. Our study describes current practice patterns and identifies barriers to universal use of real-time ultrasound guidance for insertion of CVCs.

METHODS: A national, prospective, blinded, observational survey was conducted using REDCap. Attending physicians specializing in critical care medicine (CCM) or hospital medicine (HM) from the Chest and Society of Hospital Medicine databases were surveyed. Data were collected over 8 weeks and analyzed.

RESULTS: The survey response rate was 5.9% (1,012/17,233). The majority of physicians (81.8%) report prior training in ultrasound use for CVC insertion. Moderate to very frequent use of ultrasound guidance varies by site: internal jugular vein (97.5%), peripherally inserted central catheter (73.7%), femoral vein (55.8%), and subclavian vein (36.0%). Ultrasound training during post-graduate education (residency or fellowship) has the greatest impact on skill acquisition compared to bedside training by a colleague, industry- or professional society-sponsored workshops, or computer-based training. Additional ultrasound training is most desired for insertion of subclavian (35.0%), internal jugular (23.9%), and peripherally-inserted (23.7%) CVCs. The most frequently reported barriers to ultrasound use are limited availability of ultrasound equipment (22.4%) and increased procedure time (17.3%).

CONCLUSIONS: Most attending physicians specializing in CCM and HM in the United States report routine use of real time ultrasound guidance for CVC insertion in the internal jugular vein. Limited equipment availability and prolonged procedure time are the most common barriers to use of ultrasound.

CLINICAL IMPLICATIONS: Training in ultrasound-guided CVC insertion should continue to be emphasized in post-graduate medical education. Training options for subclavian and internal jugular vein catheterization, as well as peripherally-inserted central catheter insertion, may be attractive to a significant number of physicians. Hospital systems should work to improve availability of ultrasound machines.
