The key advantage of using peripherally inserted central catheters (PICC) over triple-lumen catheters is the less risk of infection associated with their use. PICCs can be inserted peripherally, typically in the arm, and advanced to the central venous system, allowing for less invasive placement compared to triple-lumen catheters, which often require insertion via larger, more central veins and can introduce higher risks associated with those procedures.

The design of PICCs allows for a sterile technique that is easier to maintain in outpatient or long-term care settings, where the likelihood of exposure to pathogens can increase. Because PICCs are generally placed in a more controlled environment and maintained using stringent protocols, the risk of catheter-related bloodstream infections can be reduced.

Understanding this distinction is crucial, as managing infection risks is a vital component of patient safety in healthcare settings. The advantages of PICCs contribute to their preference for patients requiring medium to long-term venous access, particularly in those needing ongoing therapies such as chemotherapy or prolonged antibiotic treatment.
