The objective was to explore individuals' experiences and understandings of meticillin-resistant Staphylococcus aureus (MRSA) colonisation. Thirteen interviews were performed and processed using content analysis, resulting in the theme 'Invaded, insecure and alone'. ⋯ The described fears, limitations and inadequate professional-patient relationship generated unacceptable distress for MRSA-colonised persons. Thus, the healthcare sector should assume responsibility for managing MRSA, and healthcare workers must improve their professionalism and information skills, so as to better meet MRSA-colonised persons' needs.

This study presents data for ventilator use and ventilator-associated pneumonia (VAP) rates from the German hospital surveillance system for nosocomial infections (KISS: Krankenhaus Infektions Surveillance System). New Centers for Disease Control and Prevention (CDC) definitions became effective during 2005 and we describe the new method used by KISS to determine individual units with data at extreme ranges. The number of VAP cases per 1000 device-days was calculated and a new visual method, specifically funnel plots, was introduced to identify outliers. ⋯ Funnel plots identified 14.3% as outliers; 34 of them as high, and 22 as low, outliers. Since 2008, visual feedback to the KISS ICUs has been supplied by funnel plots. These are less prone to misinterpretation than histograms and they indicate when investigation is required for increasing VAP.

A new surveillance module for multidrug-resistant (MDR) bacteria was added to the intensive care component of the German Nosocomial Infection Surveillance System. Participating intensive care units (ICUs) report data on all patients colonised or infected with meticillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) and extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae (ESBL-EC/KP). To determine the regional distribution of MRSA, VRE and ESBL-EC/KP in Germany, incidence densities (IDs) of these bacteria per 1000 patient-days were calculated for each ICU and pooled for ICUs of five German regions for the years 2005 and 2006. ⋯ While there were no significant differences in the incidence densities of MRSA infections between regions, the IDs of VRE and ESBL-EC/KP infections showed significant regional variation. The regions also differed in the proportion of ICUs per region that reported at least one infection with MRSA, ESBL-EC/KP or VRE in 2005-2006 and these differences ranged from 82% to 91% for MRSA, from 34% to 76% for ESBL-EC/KP and from 8% to 42% for VRE. This new surveillance module enables ICUs to monitor the occurrence of MDR bacteria by comparing local incidence densities with a national reference and shows significant regional variation of MDR bacteria in Germany.

An increasing number of patients receive extracorporeal membrane oxygenation (ECMO) for life support. This study aimed to investigate the incidence and risk factors for nosocomial infection in adult patients receiving ECMO. We reviewed the medical records of adult patients who received ECMO support for more than 72h at Far Eastern Memorial Hospital from 2001 to 2007. ⋯ In the univariate analysis, the duration of ICU stay and duration of ECMO use were associated with nosocomial infection. In the multivariate analysis, only the duration of ECMO was independently associated with nosocomial infection (P=0.007). Overall, the only independent risk factor for ECMO-related nosocomial infection identified in this study was prolonged ECMO use.
