Importance of hand hygiene during invasive procedures.

Invasive devices, such as urinary catheters and peripheral and central venous catheters, can form part of essential patient care and may provide life-saving support and treatment. However, the invasive nature of these devices and the vulnerability of patients can increase the risk of acquiring a healthcare-associated infection (HCAI). This article highlights the importance of best practice in relation to insertion and management of invasive devices, incorporating hand hygiene, to reduce the risk of HCAI. Although the information can be applied to invasive devices in general, the focus is on urinary catheters.
