Vancomycin Study: Treatment of Catheter Related Bloodstream Infection Caused by Coagulase Negative Staphylococcus

Staphylococcal Infections Clinical Trial

Official title: Treatment of Catheter Related Bloodstream Infection Caused by Coagulase Negative Staphylococcus; Removal of Catheter Followed by 2 Days Compared With 7 Days Intravenous Vancomycin

Status Completed

Clinical Trial Summary

Patients admitted into the Intensive Care Unit (ICU) have an intravenous (IV) catheter (small plastic tube) placed in their vein. Very occasionally (4 times out of 100) the insertion of an intravenous catheter may cause an infection in the blood. It has been shown that the removal of the catheter and the insertion of a new one at a new site helps to get rid of this infection. Sometimes, antibiotics are also given.

Vancomycin is the antibiotic given intravenously (into the vein) to treat these catheter-related infections. At Vancouver General Hospital, some physicians may not give any vancomycin at all whereas others may treat with intravenous (IV) vancomycin for one to fourteen days.

Since there are a lack of data to support the length of IV vancomycin therapy, the investigators would like to find out if two days of IV vancomycin are as good as seven days.

Therefore, the purpose of this study is to determine if two days of IV vancomycin are as good as seven days for the treatment of catheter-related infections in the blood.

Clinical Trial Description

INTRODUCTION: Intravascular device associated bacteremia due to coagulase negative staphylococcus has become the most common nosocomial bacteremia. Despite its prevalence, no prospective study has investigated how these infections should be treated. Removal of the intravascular device is associated with a reduction in recurrence rate from 20% to 3% but the required duration of vancomycin therapy is not known. We propose to test the hypothesis that, following removal of the intravascular device, treatment with 2 days of vancomycin is equivalent to 7 days of vancomycin.

INTERVENTION: Randomized double-blind equivalence trial to test the hypothesis that 2 days is equivalent to 7 days of vancomycin treatment for intravascular device associated bacteremia due to coagulase negative staphylococcus. The definitions for the surveillance of intravascular device associated bacteremia from the Laboratory Centre for Disease Control-Health Canada will be used.

MEASUREMENTS: Surveillance blood cultures on days 4 and 9 following removal of intravascular device. Relatedness of strains will be determined by pulsed-field gel electrophoresis (PFGE). ;
