INTRODUCTION: Neutral-valve closed-system connectors can reduce the frequency of catheter colonization. Commercially available closed system connectors need to be tested and compared with each other to assess how they protect against contamination. We aimed to compare, in vitro, the efficacy of connectors NeutraClear® and MicroClave® against contamination under conditions of daily clinical practice. METHODS: The model consisted of a set of 200 blood culture bottles (BCBs) with a cannula inserted (100 closed with NeutraClear® and 100 closed with MicroClave®) that were assessed in two experiments while instilling 1 mL of saline: manipulation based on the standard of care and manipulation using gloves impregnated with a 0...

BACKGROUND AND OBJECTIVES: Coagulase negative Staphylococcus (CoNS) is frequently isolated from blood cultures but their significance is difficult to interpret. CoNS bacteria which are often previously dismissed as culture contaminants are attracting greater importance as true pathogens in the past decades. Clinical evaluation of these isolates suggests that although there is a relative increase of CoNS associated bloodstream infections in recent years, the microorganisms still remain the most common contaminants in blood cultures...

Bacterial contamination of blood components is the major infectious risk in transfusion medicine. Since platelets should be stored at room temperature that makes them an excellent growth medium for bacteria; it is mentioned as a major problem in transfusion medicine. Transfusion risk of a bacterial contaminated platelet concentrate is higher than viral pathogen such as HIV, HBV, HCV and HTLV. The objective of this study was to evaluation of the sensitivity and specificity of use of glucose and pH for bacterial screening of platelet concentrates compared to the Bact/Alert...

Health care-associated infection (HAI) rates are subject to public reporting and are linked to hospital reimbursement from the Centers for Medicare and Medicaid Services (CMS). The increasing pressure to lower HAI rates comes at a time when advances in the clinical microbiology laboratory (CML) provide more-precise and -sensitive tests, altering HAI detection in ways that may increase reported HAI rates. I review how changing CML practices can impact HAI rates and how the financial implications of HAI metrics may produce pressure to change diagnostic testing practices...
