Trial summary

In modern-day medicine, the use of central venous catheters has become unavoidable. However, their use does not come without risk. It puts patients in danger of infectious complications (catheter-related infections [CRI]), the most important of which is catheter-related bloodstream infection (CRBSI). Read more about this study

About this study

Official title: Short Daily Alcohol Locks for the Prevention of Tunneled Catheter Infection in Patients With Haematological Disease. Randomised Placebo Controlled Trial

In modern-day medicine, the use of central venous catheters has become unavoidable. However, their use does not come without risk. It puts patients in danger of infectious complications (catheter-related infections [CRI]), the most important of which is catheter-related bloodstream infection (CRBSI). CRBSI is associated with a significant increase in hospital stay and, therefore, cost of patient management, morbidity, and probably also mortality. There still is an urgent need for effective, cheap and easy to implement measures to prevent CRI that are without risk of developing antibiotic resistance.

During use, bacteria can colonize the inner surface of the catheter. This endoluminal route of infection can be prevented to some extent when an antibiotic solution is instilled in the catheter for a long enough time and on a regular basis. However, to avoid resistance from occurring, the use of antibiotics for infection prevention should remain exceptional.

The use of a non-toxic antiseptic might be a better alternative. Recently, the use of an alcohol lock solution was suggested as a promising way to prevent CRBSI and the compatibility of polyurethane and silicone catheters submerged in an alcohol solution was publicized with no biomechanical or structural changes detected after 9 weeks of immersion. The major advantage of an alcohol lock solution would be the broad antimicrobial spectrum without the risk of compromising future antibiotic treatment as, in contrast to the use of an antibiotic lock, the development of antibiotic resistance is not of concern. Furthermore it would be cheap and universally available.

In this randomised study, the efficacy of a 70% alcohol lock solution for the prevention of CRBSI will be compared with placebo when applied for 15 minutes per day.

Read the detailed description

In modern-day medicine, the use of intravascular catheters has become unavoidable. In the United States, hospitals and clinics purchase more than 150 million intravascular devices each year of which more than 5 million are central venous catheters. However, their use does not come without risk. It puts patients in danger of mechanical, thrombotic and infectious complications (catheter-related infections [CRI]), the most important of which is catheter-related bloodstream infection (CRBSI). CRBSI is associated with a significant increase in hospital stay and, therefore, cost of patient management, morbidity and probably also mortality. The increase in expenses was estimated to be 15,965 US dollars per patient with a CRBSI in 1994 and even 56,167 US dollars in another more recent study.

It is clear that the prevention of CRI is of utmost importance and will help to decrease patient suffering as well as cost of patient management. Extensive and detailed evidence-based recommendations for the prevention of CRI were recently published. However, many topics remain unresolved and there still is an urgent need for effective, cheap and easy to implement preventive measures that are without risk of developing antibiotic resistance.

Catheters can become colonized with microorganisms through exoluminal (catheter insertion site) or endoluminal (hub and infusates) routes. It has been shown that, the longer a catheter remains in place, the more important the endoluminal route becomes. The endoluminal route of infection can be prevented to some extent when an antibiotic solution is instilled in the catheter for a long enough time and on a regular basis. However, to avoid resistance from occurring, the use of antibiotics in such a lock for infection prevention should remain exceptional. Although there is evidence to support the concept, methodologically appropriate clinical data on the use of antiseptic solutions for this purpose are still awaited.

Recently, the use of an alcohol lock solution was suggested as a promising way to prevent CRBSI and the compatibility of polyurethane and silicone catheters submerged in an alcohol solution was publicized with no biomechanical or structural changes detected after 9 weeks of immersion. The major advantage of an alcohol lock solution would be the broad antimicrobial spectrum without the risk of compromising future antibiotic treatment as, in contrast to the use of an antibiotic lock, the development of antibiotic resistance is not of concern. Furthermore it would be cheap and universally available.

In this randomised study the efficacy of a 70% alcohol lock solution for the prevention of CRBSI will be compared with placebo when applied for 15 minutes per day.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Alcohol-lock in people with Bacteremia, run by Erasmus Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 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 25 Sep 2009. 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 Netherlands. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Endoluminal catheter related bacteremia (time frame: at time of catheter removal). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00122642, which also lists 16 linked publications.

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 25 Sep 2009.
