Overview

Resistant organisms, once confined to hospitals, are now being transmitted in the community. Initially reported in the 1980s, community-onset infections caused by these resistant organisms are an emerging public health concern. These infections contribute to escalating healthcare costs and in some cases, increased mortality.

The media have highlighted MRSA in the community, referring to it as a “superbug.” Its transmission through close contact has increased the incidence of skin and soft tissue infections. Similar to MRSA, ESBL-producing Enterobacteriaceae were initially reported as hospital pathogens and are now found in the community as distinct clones. These infections are most often urinary tract infections caused by Escherichia coli that are resistant to the antibiotics typically used for empiric treatment. Also concerning is the escalating prevalence of C. difficile infection (CDI) in the community. In contrast to MRSA and ESBL-producing Enterobacteriaceae, this microbe is usually not antibiotic resistant. However, annual CDI death rates in the U.S. increased from about 6 per million people in 1999 to 24 per million in 2004.

This issue reviews the risk factors and outpatient treatment challenges for each of the infections listed above. Currently recommended antibiotic regimens are discussed in detail.
