title: Increased catheter-related bloodstream infection rates after the introduction of a new mechanical valve intravenous access port.
abstract: The technology of intravenous catheter access ports has evolved from open ports covered by removable caps to more-sophisticated, closed versions containing mechanical valves. We report a significant increase in catheter-related bloodstream infections after the introduction of a new needle-free positive-pressure mechanical valve intravenous access port at our institution.
