Unknown
The summary mentions the "Advanced Expert System™" which performs "systematic validation of results and interpretation of resistant phenotypes". While this sounds like it could potentially utilize AI/ML for complex pattern recognition and interpretation, the summary does not explicitly state that AI or ML is used. The description of the system's function is too general to definitively confirm the presence of AI/ML.

No
This device is for automated antimicrobial susceptibility testing and identification of microorganisms from isolated colonies, not for directly treating a disease or condition in a patient. It is used in laboratory settings for diagnostic purposes.

Yes

The device is intended for the automated quantitative and/or qualitative antimicrobial susceptibility testing and identification of various clinically significant microorganisms, which are diagnostic activities.

No

The device description explicitly states it includes a physical instrument (VITEK® COMPACT PRO instrument) with internal computer, monitor, keyboard, mouse, and barcode scanner, which performs physical actions like sample well filling, incubation, and optical readings. While software is a component, it is part of a larger hardware system.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the device is for "automated quantitative and/or qualitative antimicrobial susceptibility testing of isolated colonies" and "automated identification of most clinically significant anaerobic organisms and Corynebacterium species, fermenting and nonfermenting Gram-negative bacilli, Gram-positive organisms, fastidious organisms, and yeasts and yeast-like organisms." These are all tests performed on biological samples (isolated colonies of microorganisms) in vitro (outside the body) to provide information for diagnosis or treatment.
  • Device Description: The description details an automated instrument that processes reagent cards with sample inoculum, incubates them, and performs optical readings. This process is consistent with performing diagnostic tests on biological samples.
  • Input Imaging Modality: The use of "Optical readings" further supports the idea that the device is analyzing the results of a reaction or growth occurring on the reagent cards, which is typical of IVD tests.
  • Intended User / Care Setting: The intended user is "laboratory use by professional users who are trained in microbiology and good laboratory practices," which is the typical setting for performing IVD tests.
  • Summary of Performance Studies: The performance studies described (Quality control testing, Reproducibility performance, Accuracy of MICs) are all standard evaluations for IVD devices to demonstrate their reliability and accuracy in providing diagnostic information.
  • Key Metrics: The key metrics listed (Essential Agreement (EA), Categorical Agreement (CA), Reproducibility, Quality Control passing percentage) are commonly used to assess the performance of IVD devices, particularly those related to antimicrobial susceptibility testing and identification.
  • Predicate Device(s): The mention of a predicate device, the VITEK® 2 SYSTEM, which is a PMA-approved device (indicating it's a medical device requiring premarket approval), further reinforces that the VITEK® COMPACT PRO is also a medical device, and given its intended use, specifically an IVD.

All these factors strongly indicate that the VITEK® COMPACT PRO is an In Vitro Diagnostic device.

Prior to the clinical performance evaluation, verification testing included a performance evaluation, which utilized all the VITEK® 2 Antimicrobial Susceptibility Testing - i.e. GN, GP, YS, and ST test card classes.

Quality Control (QC) Testing

The quality control testing evaluated the performance of the VITEK® COMPACT PRO instrument as compared to the established package insert quality control ranges for thirty-nine antimicrobial agents. covering all the VITEK® 2 Antimicrobial Susceptibility Testing card classes (i.e. GN. GP. YS, and ST test cards). Thirteen quality control organisms were tested. Each isolate was tested at least twenty times at least three of the clinical evaluation trial sites. Quality control isolates were tested with the VITEK® 2 60 using manual dilution mode and the VITEK® EVO Compact, using the same initial McFarland suspension. Testing demonstrated the VITEK® COMPACT PRO gave acceptable quality control results with QC passing >99% for each of the AST card classes tested.

Reproducibility

Reproducibility performance was evaluated by testing isolates in triplicate for three trial sites. Reproducibility test sets were selected based on the following criteria:

  • Separate test sets were selected for each antimicrobial. ●
  • . Each set included at least 10 strains.
  • Each set included at least 2 strains with on-scale results for each antimicrobial. .

The overall reproducibility rate was calculated as the percentage of the total number of results that were within one doubling dilution of the modal card result. If a mode could not be established, the median result was used. Results within ± one doubling dilution from the mode were used to calculate reproducibility performance. Analysis was performed for each drug/organism combination which revealed acceptable reproducibility. The VITEK® COMPACT PRO reproducibility testing demonstrated that all the VITEK® 2 AST test cards/antimicrobials showed a >97% reproducibility in the best case and a >95% reproducibilitv in the worst case.

Clinical Performance Evaluation

The accuracy of MICs obtained by the VITEK® COMPACT PRO was evaluated using representative, clinically relevant strains, tested on all the VITEK® 2 AST test class (i.e. AST GN, GP, ST, and YS). Each strain was grown on appropriate agar media for appropriate incubation times and the cultured isolates were tested one time with both the VITEK® 2 and the VITEK® COMPACT PRO, using the same initial McFarland suspension with each antibiotic panel.

The MICs obtained using the VITEK® COMPACT PRO were then compared to the MICs obtained using the VITEK® 2. MICs obtained using the VITEK® COMPACT PRO demonstrated very high agreement in essential agreement (EA) and categorical agreement (CA) with the MICs obtained using the VITEK® 2. Essential Agreement (EA) was defined as MIC results obtained from the VITEK COMPACT PRO that were within one doubling dilution of the MIC results obtained from the VITEK 2. Category Agreement (CA) was defined as MIC interpretations (S/SDD/I/R) that were the same between the VITEK COMPACT PRO and VITEK 2. Analysis was performed for each drug/organism combination which revealed acceptable EA and CA. The clinical performance evaluation demonstrated that in comparison with the accuracy for the VITEK® 2 AST GN cards was 98.8% EA and 97.3% CA. the VITEK® 2 AST GP cards was 99.5% EA and 97.4% CA, the VITEK®2 AST ST cards was 98.5% EA and 98.7% CA, and the VITEK®2 AST YS cards was 100% on both EA and CA.
