A barrier system is provided for use in reducing infections associated with a percutaneous medical device, such as a catheter, that is disposed within a percuteneous incision. Such a barrier system can include: a barrier device having a skin-contacting surface and a catheter-receiving surface and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. The barrier device can include a conduit configured to receive the catheter. Alternatively, the barrier device can include a groove in a base surface that is configured to receive the catheter. A system that includes a medical device, the barrier device, and adhesive can also be provided.
