Each year, the CDC carefully monitors Healthcare Associated Infections (HAIs) through the National Healthcare Safety Network (NHSN) surveillance system. This robust capability tracks not only HAIs but also key influencing factors to infections, such as Antibiotic Resistance patterns. This sophisticated infection surveillance system is also used to financially reward or penalize top or low performers, with the ultimate goal of eliminating HAIs. The data gathered by CDC is used in collaboration with the Centers for Medicare and Medicaid Services to influence future payment models. The resources on this page summarize the current burden of Healthcare Associated Infections, CMS reporting requirements, and current trends associated with Antibiotic Resistance.
