NHSN Annual Update:
Antimicrobial-Resistant Pathogens Associated With Healthcare-Associated Infections

Annual Summary of Data Reported to the National Healthcare Safety Network at the Centers for Disease Control and Prevention, 2006–2007

Antimicrobial-resistant pathogens that cause healthcare-associated infections (HAIs) pose an ongoing and increasing challenge to hospitals, both in the clinical treatment of patients and in the prevention of the cross-transmission of these problematic pathogens.  Describing the magnitude of the problem with respect to these antimicrobial-resistant pathogens is challenging, because the levels of antimicrobial resistance vary for different types of healthcare facilities and for different geographic areas, and some resistance phenotypes are difficult for laboratories to detect. However, the findings from such attempts may help the infection control and public health communities target problems and utilize resources more efficiently.

The research, published in Infection Control and Hospital Epidemiology, found one third of hospitals did not have a written policy on antibiotic use, and only 35% had an antibiotic stewardship programme.

We assessed methicillin‐resistant Staphylococcus aureus (MRSA) infection and colonization in hospitalized prisoners. Of 434 admission surveillance cultures, 58 (13%) were positive for MRSA. The sensitivity of admission surveillance cultures of samples from the anterior nares was 72% and increased to 84% when the calculation included cultures of wound samples. Hospitalized prisoners are at high risk for MRSA infection and colonization, and surveillance should include cultures of nares and wound samples.
