Hospitals are turning to an antibiotic SWAT team to win the war against "superbugs." The efforts are known as antimicrobial stewardship programs, and team top pharmacists, infectious-disease specialists, and microbiologists. The groups monitor the use of a hospital's antibiotics and restrict prescriptions of specific drugs when they become less effective at fighting infections. The hospital programs come as legislation is pending in Congress to create a federal office of antimicrobial resistance and a public-health network to help detect emerging resistant strains of bacteria before they become a national threat.
