Modern trends in infection control practices in intensive care unitsHospital-acquired infections (HAIs) are common in intensive care unit (ICU) patients and are associated with increased morbidity and mortality. There has been an increasing effort to prevent HAIs, and infection control practices are paramount in avoiding these complications. In the last several years, numerous developments have been seen in the infection prevention strategies in various health care settings. This article reviews the modern trends in infection control practices to prevent HAIs in ICUs with a focus on methods for monitoring hand hygiene, updates in isolation precautions, new methods for environmental cleaning, antimicrobial bathing, prevention of ventilator-associated pneumonia, central line-associated bloodstream infections, catheter-associated urinary tract infections, and Clostridium difficile infection.

Effect of a Multidisciplinary Team Approach to Eradicate Central Line Associated Blood-Stream Infections (CLABSI)Introduction: CLABSI remains a significant problem in the intensive care unit. Hypothesis: A multimodal approach for the insertion and care of CVC will prevent CLABSI. Methods: A Critical Care Operations Committee was formed to transform care in 8 intensive care units (ICU) in an academic medical center in 9/2004. One goal was to reduce CLABSI. Using evidence based medicine, a clinical practice guideline was developed that incorporated the use of maximum barrier precautions, chlorhexidine skin preparation, avoidance of the femoral insertion site, dedicated catheter cart, a check list, the tracking of high risk CVC, anti-septic or antimicrobial impregnated catheters, a recommendation to use ultrasound guidance when inserting CVC in the internal jugular vein, daily determination of the need for the CVC and treatment of CLABSI as a critical event.CLABSI were adjudicated by the hospital epidemiologist and CVC days were tracked. Rates of CLABSI were followed from 9/2004 through 7/2011. The Spearman correlation coefficient was used for statistical evaluation. A p Results: CLABSI rates (per 1000 catheter-days) declined dramatically from 2004 to 2011 (p Conclusions: A multimodal approach to CVC insertion and care reduces CLABSI by over 90%. Our ultimate goal is the complete eradication of CRBSI in our institution.

The bundle "plus": the effect of a multidisciplinary team approach to eradicate central line-associated bloodstream infectionsBACKGROUND: Central line-associated bloodstream infections (CLABSIs) have decreased significantly over the last decade. Further reductions in CLABSI rates should be possible. We describe a multidisciplinary approach to the reduction of CLABSIs. METHODS: This was an observational study of critically ill patients requiring central venous catheters in 8 intensive care units in a tertiary medical center. We implemented a catheter bundle that included hand hygiene, education of providers, chlorhexidine skin preparation, use of maximum barrier precautions, a dedicated line cart, checklist, avoidance of the femoral vein for catheter insertion, chlorhexidine-impregnated dressings, use of anti-infective catheters, and daily consideration of the need for the catheter. Additional measures included root cause analyses of all CLABSIs, creation of a best practice atlas for internal jugular catheters, and enhanced education on blood culture collection. Data were analyzed using the Poisson test and regression. RESULTS: CLABSI, catheter use, and microbiology were tracked from 2004 to 2012. There was a 92% reduction in CLABSIs (95% lower confidence limit: 67.4% reduction, P < 0.0001). Central venous catheter use decreased significantly from 2008 to 2012 (P = 0.032, -151 catheters per year, 95% confidence limits: -277 to -25), whereas peripherally inserted central catheter use increased (P = 0.005, 89 catheters per year, 95% confidence limits: 50 to 127). There was no apparent association between unit-specific Acute Physiology And Chronic Health Evaluation III/IV scores and CLABSI. Three units have not had a CLABSI in more than a year. The most common organism isolated was coagulase-negative staphylococcus. Since the implementation of minocycline/rifampin catheters, no cases of methicillin-resistant Staphylococcus aureus CLABSI have occurred. CONCLUSIONS: The implementation of a standard catheter bundle combined with chlorhexidine dressings, minocycline/rifampin catheters, and other behavioral changes was associated with a sustained reduction in CLABSIs.
