Impact of education, information on hand hygiene compliance

The investigators found there was greater hand hygiene compliance when health care workers were leaving patient rooms, when going in or out of the room of a patient that was known to be infected or colonized with antibiotic-resistant bacteria, and when caring for patients during the evening shift. In the publication, the investigators also outlined the infection control and prevention program utilized at Rhode Island Hospital that significantly improved hand hygiene compliance among doctors, nurses and support staff.

Hospital-associated infections have a significant impact on health care in the U.S. According to the Centers for Disease Control and Prevention (CDC), in 2002, such infections developed in 1.7 million patients and were associated with nearly 100,000 deaths. In 2009, the CDC estimated that the annual direct medical costs of such infections in U.S. hospitals was $36 billion to $45 billion.

"Hand hygiene is the most important intervention to reduce the risk of hospital-associated infections, but many hospitals have struggled to develop a culture of safety where high hand hygiene compliance becomes the norm rather than the exception," said principal investigator Leonard Mermel, D.O., medical director of the department of epidemiology and infection control at Rhode Island Hospital. "With use of a process improvement program that engaged hospital administration at the highest levels, as well as hospital staff from housekeepers, to facilities engineers, to nurses, doctors and others, we were able to dramatically improve our hand hygiene compliance in a sustainable fashion, thereby reducing the potential for harm in our patients."
