Nice idea from researchers at the University of Bath but difficult to see been adopted on a wide scale. Adding a coating to a catheter adds cost that would have to be borne mostly by the NHS in the UK.
Also the dye is released around 12 hours before catheter blockage by the infective bacteria (Proteus mirablis). The system therefore gives an early warning to change the catheter and treat the infection before it causes serious damage. Maybe better to concentrate on avoiding infection in the first place. Focusing resources on the high risk patients.
Great work though by the University of Bath. Focus on decreasing the incidence of Catheter Associated Urinary Tract Infections (CAUTI) will have a positive impact on overall medical treatment costs and patient experience.
A research team led by the University of Bath has developed an early warning system for urinary catheter infections, a problem which can cause severe risk to patients’ health and costs the NHS an estimated £120 million per year.
