Complications and cost associated with parenteral nutrition delivered to hospitalized patients through either subclavian or peripherally-inserted central catheters

Background and aims: Total parenteral nutrition (TPN) is typically delivered through catheters inserted into the superior vena cava (SVC) via a subclavian or internal jugular vein approach. A peripherally-inserted central venous catheter (PICC), utilizing a cephalic or basilic venous approach, may provide a safe alternative to the standard catheter approach and, because non-physician providers can insert the PICC, may introduce a potential cost-savings to health care institutions. We sought to determine if PICC lines are safer and more cost-effective than the standard central venous catheter approach for hospitalized patients who require TPN. Methods: One hundred and two hospitalized patients (age range, 18–88 years) who required TPN were prospectively randomized to receive therapy via a centrally-inserted subclavian catheter (n=51) or a peripherally-inserted PICC line (n=51). The primary end-point was the development of a complication requiring catheter removal. Other end-points included catheter infection and thrombophlebitis. Cost associated with insertion and maintenance of each catheter was also studied. Results: Complication-free delivery rate (without the need to remove or replace the catheter) was 67% for subclavian catheters and 46% for PICC lines (P
