Health minister John Denham has announced that all trusts will be required to monitor levels of hospital-acquired infection, focusing on infections that pose a serious threat to health such as 'superbug' methicilin-resistant staphylococcus aureus. The government aims to prevent 15 per cent of the 100,000 HAIs annually, saving the NHS £150m a year. Monitoring will be developed to cover infections following orthopaedic surgery, bacterial bloodstream infections and HAIs that come to light after a patient has been discharged, building on last year's infection-control standard. That gave chief executives responsibility for ensuring good infection-control measures - including infectioncontrol teams - were in place.
