Empiric Methicillin Resistant Staphylococcus aureus Coverage in the Early Ventilator Associated Pneumonia Window: If and When.
Choice of empiric antibiotic(s) for early ventilator associated pneumonia (VAP) involves weighing the risks of potential infection with multi-drug resistant (MDR) pathogens against those of over-exposure to broad-spectrum agents. Although early VAP is believed to be rarely caused by MDR pathogens, the overall incidence of all methicillin resistant Staphylococcus aureus (MRSA) infections is increasing. We questioned if MRSA VAP is becoming more common and if these infections were occurring earlier in the patient's hospital course. We hypothesized that 1) early (2-4 d from intubation) VAP caused by MRSA is relatively uncommon and 2) those patients with early VAP because of MRSA had risk factors associated with a MDR organism infection. ⋯ These data suggest that the incidence of MRSA VAP is stable. Those patients with early MRSA VAP demonstrated traditional MDR risk factors. Patients without risk factors in the early time period could effectively be ruled out from having MRSA VAP and likely do not require empiric MRSA coverage.

Comparative StudyNeutrophil to Lymphocyte and Platelet to Lymphocyte Ratios Are More Effective than the Fournier's Gangrene Severity Index for Predicting Poor Prognosis in Fournier's Gangrene.
We investigated the value of the neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as markers of mortality in patients with Fournier's gangrene. ⋯ The Fournier's Gangrene Severity Index scoring system was not associated with determining poor prognosis, however, high NLR and high PLR were associated with predictors of mortality in patients with Fournier's gangrene.

Educational Antimicrobial Stewardship Intervention Ineffective in Changing Surgical Prophylactic Antibiotic Prescribing.
High rates of inappropriate use of prophylactic antibiotics in surgery continue to be reported in the literature, with many institutions designing interventions aimed at improving prescription. This study evaluates the surgical arm of a clinician-focused educational antimicrobial stewardship program implemented in February 2014 at Blacktown Hospital, Australia. ⋯ The educational intervention studied demonstrated no substantial change to overall adherence. Given the frequent failure of such interventions, stronger and more directly mandated adoption of prescribing guidelines is recommended for surgical services. Future consideration should be given to focused computer-based solutions, integrated with electronic medical records where possible.
