Outcomes of Clostridium difficile-suspected diarrhea in a French university hospital.
Clostridium difficile infection (CDI) produces a variety of clinical presentations ranging from mild diarrhea to severe infection with fulminant colitis, septic shock, and death. CDI puts a heavy burden on healthcare systems due to increased morbidity and mortality, and higher costs. We evaluated the clinical impact of CDI in terms of complications and mortality in a French university hospital compared with patients with diarrhea unrelated to CDI. ⋯ Death was attributable to CDI in 15 patients (6.4%). Complications are more frequent among CDI cases than in patients with diarrhea not related to C. difficile. Assessment of CDI is necessary to ensure allocation of sufficient resources to CDI prevention.

An evaluation of risk factors to predict target concentration non-attainment in critically ill patients prior to empiric β-lactam therapy.
To determine whether target concentration non-attainment can be anticipated in critically ill patients prior to initiating empiric β-lactam antibiotic therapy based on readily available clinical factors. Retrospective review of consecutive patients treated with piperacillin or meropenem and who underwent therapeutic drug monitoring (TDM) at St Vincent's Hospital (Sydney, Australia) between January 2013 and December 2015 was performed. Predefined subgroups were patients who received continuous renal replacement therapy (CRRT) and those who did not (non-CRRT). ⋯ No predictor variable was found to be significantly associated with Cmin ≤ MIC for the CRRT cohort. Evaluating the risk of target concentration non-attainment using simple clinical factors is possible at the bedside for non-CRRT patients prior to empiric antibiotic initiation. Clinicians should be wary of selecting doses based on the product information especially when treating younger male patients with apparently 'normal' renal function.
