Antimicrobial usage in German acute care hospitals: results of the third national point prevalence survey and comparison with previous national point prevalence surveys.

Objectives: Previous point prevalence surveys (PPSs) revealed the potential for improving antimicrobial usage (AU) in German acute care hospitals. Data from the 2016 German national PPS on healthcare-associated infections and AU were used to evaluate efforts in antimicrobial stewardship (AMS).

Methods: A national PPS in Germany was organized by the German National Reference Centre for Surveillance of Nosocomial Infections in 2016 as part of the European PPS initiated by the ECDC.

Pathogen-specific mortality in very low birth weight infants with primary bloodstream infection.

Objective: Mortality in very low birth weight infants following microbiology confirmed primary bloodstream infections varies with the type of causative pathogen. Given evidence from other studies that infections with gram negative bacteria and fungi cause a higher case fatality risk. We tried to confirm this in a nation-wide multi-center trial.

Outbreak of carbapenem-resistant Acinetobacter baumannii carrying the carbapenemase OXA-23 in a German university medical centre.

A prolonged outbreak of carbapenem-resistant Acinetobacter baumannii in a German university medical centre in 2006 was investigated; the investigation included a descriptive epidemiological analysis, a case-control study, environmental sampling, molecular typing of A. baumannii isolates using PFGE and repetitive-sequence-based PCR (rep-PCR) typing, and detection of OXA-type carbapenemases by multiplex PCR. Thirty-two patients acquired the outbreak strain in five intensive care units (ICUs) and two regular wards at a tertiary care hospital within 10 months.
