Chapter Seven – Invasive Devices

The use of invasive devices to deliver short-term treatments, relief of problems such as urinary retention, and long-term therapies has revolutionised healthcare. Invasive devices breach the normal defences of the body and therefore provide potentially easy access for micro-organisms.1 In addition to their widespread use as part of in-patient hospital care, many patients now live with long-term devices in situ. Such devices are managed by the patients themselves, family or caregivers, or by community healthcare workers. All healthcare personnel working in acute and community settings therefore need an understanding of how to manage invasive devices in a manner that minimises the risk of infection.2 This chapter focusses on invasive devices, common treatments associated with them, and the specific infection prevention measures necessary to protect patients when they are in use.
