About this study

Bloodstream infections (BSI) are a major cause of morbidity and mortality. Bloodstream infections are also costly and result in prolonged hospital stays. The duration of therapy necessary to clear blood stream infections is unknown and no study has systematically addressed this issue. However, the use of antimicrobials is not without consequence. These include financial cost, side-effects, promotion of superinfection (especially Clostridium difficile-associated diarrhea), and the promotion of microbial resistance. This study hypothesizes that a procalcitonin (host biomarker) and endotoxin (microorganism biomarker) guided treatment plan could significantly decrease unnecessary exposure to antibiotics in patients with bloodstream infections.

Read the detailed description

Bloodstream infections (BSI) are a major cause of morbidity and mortality. Community-onset BSI have an overall attributable mortality of 10-13% while nosocomial BSI mortality ranges are quite variable from 12-80%. Bloodstream infections are also costly and result in prolonged hospital stays. Nosocomial BSIs have been shown to increase length of stay by 5-25 days and increase costs $23,000 - 40,000 above matched controls. The duration of therapy necessary to clear blood stream infections is unknown and no study has systematically addressed this issue. The use of antimicrobials is also not without consequence. These include financial cost, side-effects, promotion of superinfection (especially Clostridium difficile-associated diarrhea), and the promotion of microbial resistance. This study hypothesizes that a procalcitonin (host biomarker) and endotoxin (microorganism biomarker) guided treatment plan could significantly decrease unnecessary exposure to antibiotics in patients with bloodstream infections.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Optimal length of treatment

    To determine the optimal length of treatment by observing the normalization of procalcitonin (PCT) and Endotoxin levels, compared with the length of treatment by standard of care.

    Measured: 30 days

Secondary outcomes (1)

  1. Association of procalcitonin and endotoxin levels and outcomes

    To determine if procalcitonin and endotoxin levels (or lack of decrease) are associated with treatment failure, complication, survival, cost, length of stay, progression to severe sepsis, or superinfections.

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

An observational study of Bloodstream Infection, run by University of Nebraska at 1 site in United States.

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 1 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 15 Sep 2023. 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 United States. 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?

Optimal length of treatment (time frame: 30 days). 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 NCT00870623, which also lists 26 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 15 Sep 2023.
