We present the results of a confidential telephone survey of ENT units in England on the disinfection of flexible fibre-optic nasendoscopes out-of-hours. The on-call residents of 124 units were contacted and questioned. In 35.1 per cent of units surveyed, the on-call resident was primarily responsible for cleaning the scopes after use. Only 46 per cent of these junior doctors had access to a chemical sterilant to allow for high-level disinfection of these scopes. Provision for disinfection of scopes was poorer in teaching hospitals and in units that served inner city populations. Only 12.1 per cent of Senior House Officers (SHOs) received any training in disinfection techniques and only 25.5 per cent of units kept a register of patients nasendoscoped out-of-hours for purposes of contact tracing.
