Which long-term device is associated with the lowest risk for infection?

• A. External tunneled catheter
• B. Peripherally inserted catheter
• C. Implanted port
• D. Groschong catheter

Answer: (C)

The implanted port is recognized for being associated with the lowest risk of infection among long-term vascular access devices. This is largely due to its design and the way it is accessed. Unlike external devices, which remain exposed and provide a pathway for bacteria to enter the bloodstream, an implanted port is completely subcutaneously implanted, making it less susceptible to external contamination. When an implanted port is in use, it requires needle access to a reservoir that is beneath the skin, which significantly reduces the chances of infection compared to external lines or catheters. Additionally, the lack of external components minimizes exposure to the environment, lowering infection risk even further. Regular site care and maintenance also contribute to maintaining its sterility. In contrast, other devices, like external tunneled catheters and peripherally inserted catheters, have parts that remain outside of the body, making them more vulnerable to infections. Therefore, the implanted port is favored for patients needing long-term access where infection risk is a major concern.
