Decontamination methods for flexible nasal endoscopes

A national survey was carried out to investigate the current UK practice for decontaminating flexible nasal endoscopes. A postal questionnaire was sent to Sisters in Charge of 200 ear, nose and throat (ENT) outpatient departments in the UK, with an overall response rate of 60.5%. Decontamination with chlorine dioxide wipes was the most favoured method, used in 58% of the hospitals that participated in this survey. Automated machines were also used in many places (34%). Only a few hospitals used flexible sheaths (7%). Many departments do not use a separate protocol for high-risk patients.
