Prevention of nosocomial infections and antibiotic resistance in nursing homes

Background. Nosocomial infections and multidrug-resistant organisms are an increasing problem in nursing homes worldwide; therefore, new approaches for infection control need to be developed. Objectives. This article gives an overview of infections in nursing homes, their medical treatment and previous measures for infection prevention. Materials and methods. The article is based on a selective literature search including the literature database PubMed. In particular, scientific studies on the prevalence of nosocomial infections in German nursing homes, publications for medical care in long-term care facilities in Europe and international studies for infection prevention were evaluated. Results. The basis for an effective reduction of infections is the establishment of a surveillance system. All participating medical professionals provide feedback about local infections and resistance situations and the presence of risk factors, such as urinary catheters or chronic wounds. Only then can targeted antibiotic strategies be adapted and the effectiveness of preventive measures, such as hand disinfection is continuously reviewed. So far, in particular multimodal, multidisciplinary prevention projects were successful. These included frequent staff training, reduction of urinary catheters and a rational use of antibiotics. Conclusions. Most prevention models have been previously tested in hospitals. A possible applicability of the results to the infection prevention in long-term care facilities has so far hardly been studied. Accordingly, further studies on infection control in nursing homes are absolutely necessary.
