IMPORTANCE Contamination of the skin and clothing of health care personnel during removal of personal protective equipment (PPE) contributes to dissemination of pathogens and places personnel at risk for infection. OBJECTIVES To determine the frequency and sites of contamination on the skin and clothing of personnel during PPE removal and to evaluate the… (More)
UNLABELLED Clostridium difficile is a leading cause of nosocomial infections worldwide and has become an urgent public health threat requiring immediate attention. Epidemic lineages of the BI/NAP1/027 strain type have emerged and spread through health care systems across the globe over the past decade. Limiting person-to-person transmission and eradicating… (More)
A Clostridium difficile infection (CDI) stewardship initiative reduced inappropriate prescription of empirical CDI therapy and improved timeliness of treatment and adherence to clinical practice guidelines for management of CDI. The initiative required minimal resources and could easily be incorporated into traditional antimicrobial stewardship programs.
BACKGROUND The intestinal microbiota protect the host against enteric pathogens through a defense mechanism termed colonization resistance. Antibiotics excreted into the intestinal tract may disrupt colonization resistance and alter normal metabolic functions of the microbiota. We used a mouse model to test the hypothesis that alterations in levels of… (More)
We used a colorimetric assay to determine the presence of chlorhexidine on skin, and we identified deficiencies in preoperative bathing and daily bathing in the intensive care unit. Both types of bathing improved with an intervention that included feedback to nursing staff. The assay provides a simple and rapid method of monitoring the performance of… (More)
In an observational study, we found that healthcare personnel frequently acquired Clostridium difficile on their hands when caring for patients with recently resolved C. difficile infection (CDI) (<6 weeks after treatment) who were no longer under contact precautions. Continuing contact precautions after diarrhea resolves may be useful to reduce… (More)
A portable booth designed to disinfect full-body coverage protective equipment before removal using ultraviolet-C radiation resulted in at least 3 log reductions in bacteriophage MS2 and methicillin-resistant Staphylococcus aureus within 3 minutes. The booth could be useful for disinfection of contaminated protective equipment before removal during care of… (More)
Hospital floors are frequently contaminated with pathogens, but it is not known whether floors are a potential source of transmission. We demonstrated that a nonpathogenic virus inoculated onto floors in hospital rooms disseminated rapidly to the hands of patients and to high-touch surfaces inside and outside the room.

Effective use of personal protective equipment (PPE) is essential to protect personnel and patients in health care settings. However, in a survey of 222 health care personnel, PPE training was often suboptimal with no requirement for demonstration of proficiency. Fourteen percent of physicians reported no previous training in use of PPE.
No new acquisition of Clostridium difficile occurred among 12 hospitalised patients receiving tigecycline, and pre-existing colonisation was reduced to undetectable levels in 2 patients. Moreover, 91% of stool suspensions obtained during tigecycline therapy exhibited inhibitory activity against C. difficile. These results suggest that tigecycline achieves… (More)
