Rapid Testing for Bacterial Blood Infections
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method to quickly identify bacteria causing blood infections. The usual process takes up to three days, but the new test, the T2Bacteria® Panel, provides results much faster. This speed could help doctors select the right antibiotics sooner and avoid unnecessary ones, which can be harmful. The trial involves adults who received the antibiotic vancomycin in the emergency room due to suspected blood infections. As an unphased trial, it offers patients the chance to contribute to groundbreaking research that could enhance future diagnostic methods.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, since the trial involves patients already on intravenous vancomycin, it seems likely that you would continue with this medication if it has been prescribed.
What prior data suggests that the T2Bacteria® Panel is safe for use in diagnosing bacterial bloodstream infections?
Research has shown that the T2Bacteria® Panel is safe for people. The FDA has already approved this test to help diagnose bacterial infections in the blood. Studies have found that it can quickly and accurately detect certain bacteria without needing to grow them in a lab first. The T2Bacteria Panel is highly accurate, correctly identifying bacteria 100% of the time when present and confirming their absence 98.4% of the time.
These results suggest that the test is well-tolerated and does not pose significant risks to patients. Additionally, using this test can lead to faster treatment decisions, reducing unnecessary antibiotic use and potentially shortening hospital stays. Overall, the T2Bacteria Panel is a safe and effective tool for better managing bacterial blood infections.12345Why are researchers excited about this trial?
Researchers are excited about the T2Bacteria® Panel because it offers a rapid, direct-from-blood testing method for bacterial blood infections. Unlike traditional blood cultures, which can take days to yield results, the T2Bacteria® Panel can potentially identify bacterial infections within hours. This speed can lead to quicker diagnosis and treatment, reducing the time patients spend in uncertainty and possibly improving outcomes by allowing timely interventions.
What evidence suggests that this trial's treatments could be effective for bacterial blood infections?
In this trial, participants will be divided into two groups to evaluate the effectiveness of the T2Bacteria® Panel. Research has shown that the T2Bacteria® Panel, which some participants will receive, effectively identifies bacterial infections directly from blood samples. Earlier studies demonstrated that this test correctly identified bacteria in a high percentage of cases, with a sensitivity of 84.2% and a specificity of 85.9%. It also achieved a 100% positive percent agreement, meaning that when it gives a positive result, it consistently matches other testing methods. This rapid testing method can lead to quicker, more targeted treatment, reducing the time patients spend in intensive care and in the hospital overall. Using the T2Bacteria® Panel helps avoid unnecessary use of broad-spectrum antibiotics, minimizing side effects and lowering the risk of antibiotic resistance. Meanwhile, the other group will receive usual care, which involves standard blood cultures without direct-from-blood testing.36789

Are You a Good Fit for This Trial?
Adults over 18 who are in the Emergency Department at Vanderbilt University Hospital, have been given intravenous vancomycin, and had blood cultures ordered within 12 hours of arriving. The trial is for those suspected to have a bacterial bloodstream infection.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either usual care with blood cultures or direct-from-blood testing using the T2Bacteria® Panel
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- T2Bacteria® Panel
- Usual Care
Trial Overview
The study compares the T2Bacteria Panel, which tests directly from blood for bacteria, with usual care using blood cultures that take longer to show results. It aims to see if this rapid test can improve antibiotic use and patient outcomes.
How Is the Trial Designed?
2
Treatment groups
Active Control
Patients will receive blood cultures and will not receive direct-from-blood testing.
In addition to usual care, patients will receive direct-from-blood testing using the T2Bacteria® Panel.
