Reduced Clostridioides difficile infection in a pragmatic stepped-wedge initiative using admission surveillance to detect colonization.

Background: Clostridioides difficile Infection (CDI) is a persistent healthcare issue. In the US, CDI is the most common infectious cause of hospital-onset (HO) diarrhea.

Objective: Assess the impact of admission testing for toxigenic C.

Dose-ranging study to assess the application of intranasal 2% mupirocin calcium ointment to eradicate Staphylococcus aureus nasal colonization.

Background: Mupirocin nasal ointment may be prescribed for decolonization prior to surgical procedures, especially for carriers of methicillin-resistant Staphylococcus aureus (MRSA). The approved regimen for decolonization of S. aureus from the anterior nares is twice daily for 5 d (10 doses).

Performance of the BD GeneOhm methicillin-resistant Staphylococcus aureus test before and during high-volume clinical use.

We evaluated the use of the BD GeneOhm MRSA real-time PCR assay (BD Diagnostics, San Diego, CA) for the detection of nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA). The initial evaluation consisted of 403 paired nasal swabs and was done using the specimen preparation provided with the kit and an in-house lysis method that was specifically developed to accommodate large-volume testing using a minimal amount of personnel time. One swab was placed in an achromopeptidase (ACP) lysis solution, and the other was first used for culture and then prepared according to the kit protocol.
