Purpose To report initial results from a European ICU surveillance programme focussing on antibiotic consumption, microbial resistance and infection control. Methods Thirty-five ICUs participated during 2005. Microbial resistance, antibiotic consumption and infection control stewardship measures were entered locally into a webapplication. Results were validated locally, aggregated by project leaders and fed back to support local audit and benchmarking. Results Median (range) antibiotic consumption was 1,254 (range 348-4,992) DDD per 1,000 occupied bed days. The proportion of MRSA was median 11.6% (range 0-100), for ESBL phenotype of E. coli and K. pneumoniae 3.9% (0-80) and 14.3% (0-77.8) respectively, and for carbapenem-resistant P. aeruginosa 22.5% (0-100). Screening on admission for alert pathogens was commonly omitted, and there was a lack of single rooms for isolation. Conclusions The surveillance programme demonstrated wide variation in antibiotic consumption, microbial resistance and infection control measures. The programme may, by providing rapid access to aggregated results, promote local and regional audit and benchmarking of antibiotic use and infection control practices.

Object. To date, reports on the clinical efficacy of intraventricularly and intrathecally administered antibiotics for the treatment of neurosurgical ventriculitis and meningitis in adults are limited. The authors aimed to evaluate the efficacy and safety of the intraventricular (IVT) and lumbar intrathecal (IT) administration of antibiotics in critically ill neurosurgical patients.Methods. Thirty-four postneurosurgical patients with meningitis and ventriculitis were studied. Intraventricular/ lumbar intrathecal antibiotics were administered due to positive CSF cultures persisting despite the use of intravenous antibiotics. The time period until CSF sterilization, changes in clinical state, and efficacy of different routes of antibiotic administration were evaluated.Results. The mean time necessary to obtain CSF sterilization was 2.9 ± 2.7 days (range 1-12 days). The CSF cultures became negative within 24 hours after the administration of IVT/IT antibiotics in 17 patients (50%) and up to 48 hours in a further 6 patients (18%). The clinical outcome of patients assessed by the modified Rankin Scale improved in 17 patients (50%), stayed unchanged in 10 patients (29%), and was impaired in 1 patient (3%). Six patients (18%) died; however, 2 of them died due to reasons not directly related to meningitis or ventriculitis, so the overall mortality rate for meningitis and/or ventriculitis was 11.8% in this group of patients. All patients with ventriculitis (n = 4) were treated by antibiotics administered via the IVT route. The average time to CSF sterilization was 6.5 days in the patients with ventriculitis. Thirty patients had clinical signs of meningitis without ventriculitis. Despite the higher ratio of unfavorable Gram-negative meningitis in the subgroup of patients treated via lumbar drainage, the mean duration of CSF sterilization was 2.2 days compared with 2.6 days in the subgroup treated via external ventricular drainage, a difference that was not statistically significant (p = 0.3). Adverse effects of IVT/IT antibiotics appeared in 3 of 34 patients and were of low clinical significance.Conclusions. Intraventricular/lumbar intrathecal antibiotics can lead to very quick CSF sterilization in postneurosurgical patients with meningitis and ventriculitis. The relapse rate of meningitis and/or ventriculitis is also very low among patients treated by IVT/IT antibiotics. Intraventricular/lumbar intrathecal administration of antibiotics appears to be an effective and safe treatment for infections of the CNS caused by multidrug-resistant organisms. In patients with signs of ventriculitis, the authors prefer the IVT route of antibiotics. This study did not prove a lower efficacy of administration of antibiotics via lumbar drainage compared with the ventricular route in patients with meningitis.

Repeated surveys among primary care paediatricians were performed annually from 1998 to 2002 in the Czech Republic. The task was to assess the prescription of antibiotics in treatment of respiratory infections in children. The results were evaluated in the light of existing guidelines and conclusions were used in a number of interventions aimed at reducing the inadequate use of antibiotics and hence preventing the potential increase of the antibiotic-resistant bacteria. In addition, data on overall consumption of antibiotics in outpatient care and trends in the prevalence of resistant strains of Streptococcus pneumoniae and Streptococcus pyogenes are discussed.

BackgroundThis study presents the results of a multidisciplinary, nosocomial MRSA outbreak investigation in an 8-bed medical intensive care unit (ICU). The identification of seven MRSA positive patients in the beginning of 2014 led to the closure of the ward for several weeks. A multidisciplinary, retrospective investigation was initiated in order to identify the reason and the source for the outbreak, describe MRSA transmission in the department and identify limitations in infection control.MethodsThe investigation comprised an epidemiological description of MRSA cases from 2012 to 2014 and a characterization of MRSA isolates, including phage-, spa- and PFGE-typing. Additionally, MRSA screening was performed from the hospital staff and the environment. To identify the reason for the outbreak, work-related, psychological and behavioral factors were investigated by impartial audits and staff interviews.ResultsThirty-one MRSA cases were registered during the study period, and 36 isolates were investigated. Molecular typing determined the outbreak strain (phage type 54/812, PFGE type A4, spa type t003) and identified the probable index case. Nasal carriage in one employee and a high environmental contamination with the outbreak strain was documented. Important gaps in nursing procedures and general management were identified. Elevated stress levels and communication problems preceded the outbreak. Compliance with hand hygiene and isolation procedures was evaluated as appropriate.ConclusionThis study demonstrates the complexity of controlling hospital-associated infections. The combined use of different typing methods is beneficial for outbreak investigations. Psychological, behavioral and other work-related factors have an important impact on the spread of nosocomial pathogens. These factors should be addressed and integrated in routine infection control practice.
