Description Healthcare-associated infections due to antibiotic-resistant bacteria are costly and deadly. Michael Rubin, MD, and Matthew Samore, MD, generated new evidence on the effect of infection-prevention practices on the transmission of antibiotic-resistant pathogens, particularly methicillin-resistant Staphylococcus aureus (MRSA). They elucidated the epidemiological mechanisms for the progressive decline in rates of MRSA colonization and infection following the nationwide implementation of a program at Veterans Affairs healthcare facilities. The program introduced active surveillance to detect MRSA colonization in patients and placement of colonized patients on contact precautions, which involve the use of gowns and gloves by visiting healthcare workers. They used rigorous methods to evaluate the impact of this program and to model its cost-effectiveness, showing that the decrease in MRSA transmission that occurred following introduction of the program was largely due to contact precautions. Further, implementation of the program likely prevented a substantial number of infections from non-MRSA organisms, and was, therefore, highly cost-effective. Their studies generated important evidence for the role of contact precautions in preventing healthcare-associated infections, an issue of critical importance in healthcare epidemiology.
