The catheter-to-vein ratio at the tip level, not the catheter type, as a risk factor for a catheter failure. A retrospective comparative study of polyurethane midline and long peripheral catheters

In patients requiring a peripheral venous access for more than seven days, long peripheral catheters (LPCs) or midline catheters (MCs) are recommended. Since MCs and LPCs share many characteristics, studies comparing devices made of the same biomaterial are needed. Moreover, a catheter-to-vein ratio>45% at the insertion point has been recognized as a risk factor for catheter related complications, but no study investigated the effect of the catheter-to-vein ratio at the catheter tip level in peripheral venous devices.
