Using Microbial Genomics to Elucidate the Source of Central-line Associated Bloodstream Infections
What this study is about
Central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infection in children and are associated with morbidity and mortality.
View original scientific description
Central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infection in children and are associated with morbidity and mortality. This study will attempt to identify the source of bloodstream infections (BSIs) in children with CLABSI because we hypothesize that many of the BSIs that are currently classified as CLABSIs are actually laboratory-confirmed bloodstream infections (LCBI) that may be a result of mucosal barrier injury (MBI), also known as MBI-LCBI. In order to study this, we will isolate bacteria from multiple body sites of children that have BSI in order to compare these bacteria to the strain growing in their blood using whole-genome DNA sequencing. We will also evaluate biomarkers of MBI of the respiratory tract and GI tract.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
