The catheter provides a site for bacteria to multiply and thrive, encased in a glue called "biofilm" which is resistant to detergent and antibiotics. This is a major source or urinary infection, blockages and leaks.The catheter provides a site for bacteria to multiply and thrive, encased in a glue called "biofilm" which is resistant to detergent and antibiotics.

In a scheme to reduce Catheter Associated Urinary Tract Infections (CAUTI), five trusts in south London are working together to reduce harm in a scheme called "No Catheter, No CAUTI".In a scheme to reduce Catheter Associated Urinary Tract Infections (CAUTI), five trusts in south London are working together to reduce harm in a scheme called "No Catheter, No CAUTI".
The campaign, run by the Health Innovation Network, aims to ensure catheters are not used inappropriately, and are removed promptly. It is hoped this will reduce these infections by 30% and, if it is successful, it will be rolled out across the NHS.The campaign, run by the Health Innovation Network, aims to ensure catheters are not used inappropriately, and are removed promptly.

Dr David Hopper, the network's clinical director, said: "The general view is that CAUTI is the most common hospital acquired infection and vastly more common than MRSA and C-difficile which are the infections that everyone knows about."

And Prof Fader warns part of the problem lies with weak regulation, saying: "Unlike with new drugs, manufacturers do not need to show that any changes they make to catheters actually work on patients."And Prof Fader warns part of the problem lies with weak regulation, saying: "Unlike with new drugs, manufacturers do not need to show that any changes they make to catheters actually work on patients."
