The prevalence of nosocomial and community acquired infections in a university hospital: an observational study

摘要: Data from Germany’s Hospital Infection Surveillance System (Krankenhaus-Infektions-Surveillance-System, KISS) (www.nrz-hygiene.de) and the national prevalence study NIDEP-1 conducted in 1994 (1) show that 400 000 to 600 nosocomial infections (NI) occur annually Germany, with 10 15 deaths (mortality = 2.6%; up 10% intensive care units) (2). The length of stay an unit is prolonged by average 5.3 (± 1.6) days if patient acquires NI (3). Apart high morbidity mortality, associated higher costs: Graf et al. calculated additional expenditure € 22 905 for surgical site infection following sternotomy (4). An investigation costs incurred pneumonia Staphylococcus aureus revealed charges 17 281 per could be attributed methicillin resistance S. (5). Prevention therefore crucial, adequate preventive measures have established. Particularly important this regard knowledge distribution NI, risk areas, patient-related factors. These efforts are supported 2011 amendment German Protection against Act (Infektionsschutzgesetz, IfSG) related establishment alignment hygiene regulations federal states. created conditions necessary improvement medical quality care. Prevalence studies can reveal weaknesses which allow needed such as process parameters This turn allows good standards secured, example via implementation guidelines. Studies various European countries rates between 3.5% 11.6% (1, 6– 10). Urinary tract (UTI) most frequent followed pneumonia, infection, primary sepsis. multicenter investigations seldom reflect individual different or respective factors facilities particularly NI. In impending IfSG lack data on at high-level university hospitals a focus surgery, we decided conduct prospective NI. Our aims were detect all (nosocomial community-acquired), identify accordingly modify practices control our own institution, introducing new prevention necessary.
