[Transmission of multidrug-resistant bacteria in ambulatory settings]

Abstract

Multidrug-resistant organisms (MDROs) such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) und extended-spectrum beta-lactamase (ESBL-) producing bacteria are an ever-expanding challenge regarding infection control and prevention strategies also in ambulatory healthcare settings. The most important transmission mode for MDROs is direct or indirect contact involving the hands of healthcare workers. Strict adherence to standard precautions (and especially adherence to alcoholic handrub use) is essential in prevention of cross-transmission. Additional measures contribute to the control of MDROs: These include flagging of patients' records, establishing standards of care for patients with MDROs, continuing education of staff, disclosure of information to other involved healthcare providers and guideline-based antibiotic treatment and prophylaxis. Optimised cooperation of ambulatory healthcare providers and hospitals regarding management and control of MDROs (networking) is a promising future option.
