Quantitative assessment of interactions between hospitalized patients and portable medical equipment and other fomites.

In an observational study, we demonstrated that hospitalized patients frequently had direct or indirect interactions with medical equipment and other fomites that are shared among patients, and these items were often contaminated with health care-associated pathogens. There is a need for protocols to ensure routine cleaning of shared portable equipment.

Chlorhexidine Only Works If Applied Correctly: Use of a Simple Colorimetric Assay to Provide Monitoring and Feedback on Effectiveness of Chlorhexidine Application.

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 chlorhexidine bathing.
