The Need


Bloodstream infections are a major healthcare concern:

  • Severe sepsis strikes 750,000 people annually in the U.S., resulting in mortality rates of up to 210,000 per year.1 Left untreated Methicillin-resistant Staph aureus (MRSA) can become severe and cause sepsis.2 The CDC considers MRSA to be a serious antibiotic resistance threat.3
  • Current culture-based lab testing methods for gram positive blood culture bottles require an additional 18-48 hours for determination of MRSA or SA.
  • Without timely results, clinicians often employ empiric treatments, using costly and inadequate antimicrobials that contribute to increased drug resistance.

The Solution


On-demand molecular testing — an ideal solution:

  • Accurate molecular detection of MRSA or SA from a gram-positive blood culture sample in about an hour
  • Simple test protocol can be run on all shifts to provide results around-the-clock
  • Provides clinicians actionable information when it is most needed
  • Easily integrates into institution septic bundle processes

The Impact


A clinical study4 showed that using the Xpert MRSA/SA BC test coupled with an infectious disease pharmacist consultation resulted in:

  • Switch to optimum antimicrobial therapy 1.7 days sooner
  • Mean length of stay was reduced 6.2 days
  • Mean hospital costs were $21,387 less per bacteremic patient
