Recent trends in central venous catheter placement: a comparison of interventional radiology with other specialties

The authors determined changing trends and growth in tunneled and nontunneled central venous catheter placement procedures. With use of Medicare billing data for tunneled and nontunneled catheter placement, a comparison was made among interventional radiology (IR), surgery, anesthesia, and internal medicine. There has been substantial growth in the placement of central venous catheters. Currently, a minority of these procedures are performed in IR departments. However, there has been significant growth in the radiologic placement of both types of catheters.
