Review Meta AnalysisUse of chlorhexidine-impregnated dressing to prevent vascular and epidural catheter colonization and infection: a meta-analysis.
Vascular and epidural catheter-related infections cause significant morbidities and mortality in hospitalized patients. This meta-analysis assessed the effect of chlorhexidine-impregnated dressing on the risk of vascular and epidural catheter bacterial colonization and infection. ⋯ Chlorhexidine-impregnated dressing is effective in reducing vascular and epidural catheter bacterial colonization and is also associated with a trend towards reduction in catheter-related bloodstream or CNS infections. A large randomized controlled trial is needed to confirm whether chlorhexidine-impregnated dressing is cost-effective in preventing bacterial infection related to vascular and epidural catheters.

The influence of metallo-beta-lactamase production on mortality in nosocomial Pseudomonas aeruginosa infections.
To assess the effect of metallo-beta-lactamase (MBL) production on Pseudomonas aeruginosa nosocomial infection mortality and to identify the determinants of such effect. ⋯ MBL-PA infections resulted in higher mortality rates most likely related to the severity of these infections and less frequent early institution of appropriate antimicrobial therapy. Empirical treatments should be reviewed at institutions with high prevalence of MBL.

Single-dose pharmacokinetics of fosfomycin during continuous venovenous haemofiltration.
Dosage recommendations for fosfomycin are available for haemodialysed patients but there are no data for patients undergoing continuous renal replacement therapy. Therefore, the present study was designed to determine the concentration-versus-time profile of fosfomycin in continuous venovenous haemofiltration (CVVH). ⋯ A regimen of 8.0 g of fosfomycin every 12 h, which is usually used in patients with intact renal function, should be an appropriate antimicrobial treatment for patients undergoing CVVH.

Which reliable pharmacodynamic breakpoint should be advised for ciprofloxacin monotherapy in the hospital setting? A TDM-based retrospective perspective.
To define in critically ill patients receiving intravenous (iv) ciprofloxacin (200 mg or 400 mg twice daily) and undergoing routine therapeutic drug monitoring (TDM) the interindividual pharmacokinetic variability and the reliable pharmacodynamic breakpoint enabled by these fixed dosing regimens according to the PK/PD principles and to the pattern of susceptibility to this antibiotic. ⋯ Lowering ciprofloxacin dosage in the presence of renal failure seems in most cases unnecessary, since drug accumulation occurred only in a few cases. Optimal pharmacodynamic exposure with fixed 200 or 400 mg twice daily regimens of ciprofloxacin may be ensured only against fully susceptible microorganisms with an MIC<0.3 mg/L. This supports the use of higher dosages in critically ill hospitalized patients, whereas the wide unpredictable interindividual pharmacokinetic variability suggests the usefulness of TDM with the intent of optimizing efficacy with ciprofloxacin therapy.

Hospital consumption of antibiotics in 15 European countries: results of the ESAC Retrospective Data Collection (1997-2002).
To collect reliable, comparable and publicly available data on hospital use of antibiotics in Europe aggregated at the national level (1997-2002). ⋯ It was cumbersome but feasible to collect ecological data on hospital antibiotic consumption in a set of 15 European countries on a retrospective basis, illustrating substantial cross-national variations in the extent and distribution of exposure to antibiotics in hospital care.
