This has been identified as a top priority in the study which focused on the dangers of transmitting the human form of Bovine Spongiform Encephalopathy (BSE) to patients from surgical instruments. The risk assessment was developed last year in consultation with the experts advising the Government on BSE and vCJD issues, the Spongiform Encephalopathy Advisory Committee (SEAC). SEAC has confirmed that the risk of surgical transmission cannot be ruled out. The procedures which carry the most risk are those involving the central nervous system and the back of the eye. Procedures involving lymphatic tissue, such as tonsils, and the front of the eye are of a lesser order of risk. The study showed that the risks of transmission are significantly reduced if instrument decontamination is carried out to the highest standards. The DoH has instructed all NHS hospitals to carry out comprehensive reviews of their decontamination procedures. As part of this work, decontamination facilities at all neurology and posterior ophthalmology centres have been inspected and any necessary improvements identified. Plans to modernise all NHS decontamination facilities are being prepared and will be backed by funding of &\#163;200m, announced in January 2001 (News, January 12).
