BACKGROUND Manual surveillance for central line-associated bloodstream infections (CLABSIs) by infection prevention practitioners is time-consuming and often limited to intensive care units (ICUs). An automated surveillance system using existing databases with patient-level variables and microbiology data was investigated. METHODS Patients with a positive(More)
In 2013, a before-and-after intervention study was conducted to evaluate the effect 24-hour intensivist coverage on length of stay and rates of catheter-associated urinary tract infection, central-line associated blood stream infection, and ventilator-associated events. Intensivist coverage for 24 hours did not decrease length of stay or result in a(More)
Mechanical ventilation provides an important, life-saving therapy for severely ill patients, but ventilated patients are at an increased risk for complications, poor outcomes, and death during hospitalization.1 The timely measurement of negative outcomes is important in order to identify potential issues and to minimize the risk to patients. The Centers for(More)
Discontinuation of reflex testing of stool submitted for Clostridium difficile testing for vancomycin-resistant enterococci (VRE) led to an increase in the number of patients with healthcare-associated VRE bacteremia and bacteriuria (0.21 vs 0.36 cases per 1,000 patient-days; P<.01). Cost-benefit analysis showed reflex screening and isolation of VRE reduced(More)
Total proteolytic activity and protein synthesis were measured in cell-free extracts of the thymus during its involution in 1-30-week-old C57Bl/6J mice, and in 10-, 12-, 14-, and 24-month-old adult mice of the same strain. The mean specific activity of the proteolytic enzymes exhibited no significant change during involution or throughout the mean life-span(More)
