Healthcare-associated infections: new initiatives and continuing challenges.

Healthcare-associated infections are a major cause of patient morbidity and mortality. Fortunately for patients and the healthcare system, there is increasing interest in this field and the growing realization that many of these infections are highly preventable. We explore some of the newer and more promising strategies for decreasing infections, including the use of practice bundles, behavioural change strategies, hand hygiene auditing, public reporting of infection rates and antimicrobial stewardship. We also identify several areas where improvement is needed, including empowering patients to prevent infections, building safer healthcare facilities and accepting the limitations of the evidence supporting some infection control interventions.
