Primary Outcome Measures:
  • Determination of clinical performance of preliminary MicroPhage S. aureus/MSSA/MRSA test directly from clinical blood culture positives. [ Time Frame: Within 48 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Qualitative feedback on the preliminary MicroPhage test protocol. [ Designated as safety issue: No ]
  • Comparative results to market-available S. aureus / MRSA tests for Blood Culture. [ Time Frame: Within 48 hours ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples Without DNA

Retention of discrepant blood culture specimens only.


Enrollment: 712
Study Start Date: July 2008
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
MicroPhage
Blood Culture positive specimens available within 24 hours of alarm.
Other: MicroPhage S. aureus / MSSA / MRSA Blood Culture Test (prototype)
In vitro diagnostic: The MicroPhage "Intervention" was to perform the MicroPhage diagnostic test to detect S. aureus in the blood culture sample and determine MSSA or MRSA status at 4 and 5 hours of test incubation. The "Intervention" results were not made available to the patient or their physician.
Standard of Care
Blood Culture positive specimens.

Detailed Description:

This is a multi-center, preclinical study to investigate the effectiveness of the performance of MicroPhage S. aureus / MSSA/MRSA test direct for blood culture. There will be no patient consent, as this is a laboratory performance study on leftover specimens. The MicroPhage test will be compared to site standards (gold standard) and market-available tests with similar indications (comparators). MicroPhage will require data to be collected at 4 hours and 5 hours following the start of the MicroPhage test. The study will last 2-3 months, depending on the accrual rate of the institution.
