Molecular Epidemiology and Risk Factors for Extended-Spectrum β-Lactamase-Producing Enterobacterales in Long-Term Care Residents.

Objectives: We aimed to assess the burden of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales in Swiss long-term care facilities (LTCFs) to describe the molecular epidemiology, describe the intrainstitutional and regional clusters of resistant pathogens, and identify independent institution- and resident-level factors associated with colonization.

Design: Cross-sectional study.

Setting And Participants: From August to October 2019, we performed a point prevalence study among residents from 16 LTCFs in Western and Eastern Switzerland (8 per region).

MRSA admission screening in a low prevalence setting - much ado about nothing?

Objective: To prospectively evaluate new guidelines for MRSA admission screening and pre-emptive isolation implemented in response to a doubling of newly diagnosed MRSA patients in 2007.

Design: One-year surveillance (04/2008-03/2009).

Setting: Patients admitted to the tertiary-care hospital in St.
