Evaluation of Clinical Performance of the Accelerate ID/AST System for Positive Blood Culture Identification & Antimicrobial Susceptibility Testing

The "Evaluation of Clinical Performance of the Accelerate ID/AST System for Positive Blood Culture Identification & Antimicrobial Susceptibility Testing" is designed to validate the clinical performance of the Accelerate ID/AST System for positive blood culture identification and susceptibility testing in a clinical setting. The data from this study will be used to support the 510(k) submission for FDA clearance and global registrations of the device intended for in vitro diagnostic use.

Detailed Description

The clinical study entitled "Evaluation of Clinical Performance of the Accelerate ID/AST System for Positive Blood Culture Identification & Antimicrobial Susceptibility Testing" is designed to demonstrate the clinical performance of the Accelerate ID/AST System for positive blood culture identification (ID) and antimicrobial susceptibility testing (AST) in a clinical setting compared to reference results. Approximately 3,000 positive blood culture samples (across all Clinical Sites) will be tested on the investigational device and reference methods. Up to 50% of samples enrolled will be comprised of seeded blood cultures prepared from clinical stock isolates. Quality Control testing will be performed each day of testing. The study population is comprised of left-over clinical specimens that are indicated as positive by blood culture monitoring systems utilized by clinical microbiology laboratories. Positive blood culture samples must be tested on the Accelerate ID/AST System within 8 hours of positivity by the blood culture monitoring system. Testing of clinical samples will continue until the required sample size for each target organism and antimicrobial agent, including sufficient on-scale and resistant strains, are tested across all the sites.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Clinical specimens that are indicated as positive by blood culture monitoring systems utilized by clinical microbiology laboratories.

Description

Inclusion Criteria:

  • De-identified positive blood culture specimens (6 mL aliquot)

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison Study - ID Performance
Time Frame: Approximately 9 months (including pre-clinical phase)
Positive and Negative Percent Agreement with Comparator Method (Vitek2) by Bacterial/Fungal Target
Approximately 9 months (including pre-clinical phase)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
