Recently, we have had a few orders to place PICC's in patients that already have an infusaport. The PICC would be used for infusing TPN. When questioned on the rationale for second central line we were told that the patient would be at an increased risk for infection if TPN infused thru their port, and or that they didn't want to ruin their port (these comments are coming from MD's and NP's). I have never heard of any data indicating the above findings. Actually, I would think that they would be at higher risk for developing an infection since they'd now have 2 central catheters in place. I have tried to google this topic, but have not been successful in finding any research to back up their concerns.
