Vancomycin Study: Treatment of Catheter Related Bloodstream Infection Caused by Coagulase Negative Staphylococcus
A study testing Vancomycin in people with Staphylococcal Infections, run by University of British Columbia at 1 site in Canada.
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. Read more about this study

About this study
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
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.
Read the detailed 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).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jun 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary outcome measurement will be the proportion of patients with early bacteriological failure (time frame: Nine days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jun 2008.
