Bloodstream infections (BSI) are a major cause of global morbidity and mortality and are increasing in incidence1,2.  When left untreated, BSIs can lead to sepsis, an inflammatory response to infection that can result in organ system failure and death.

Sepsis contributes to >35% of inpatient deaths and is the most expensive US hospital-treated conditions, representing a total cost of sepsis care for inpatient and SNF admissions conservatively estimated at more than $62 billion as of 20193,4.

In 2015, the Centers for Medicare and Medicaid Services (CMS) instituted a sepsis performance measure bundle (SEP-1) to promote better care for sepsis patients5. A recent study evaluating changes and outcomes that arose from SEP-1 implementation showed that appropriate antibiotic treatment was only started in half of the cases and concluded that there were no improvements in clinical outcomes when initiating the Sep-1 bundle and that revising the measure may optimize its future effect6

The current methods for detecting and treating sepsis are hindered by lack of sensitivity and extended waiting periods for blood culture positivity. When every hour delay in time to appropriate therapy decreases survival rates by 7.6%, it is imperative that patients receive targeted therapy as soon as possible7. The T2Bacteria® Panel provides species-specific results, directly from whole blood within 3 to 5 hours of first blood draw, often before the second dose of empiric antibiotics are given. This enables clinicians to target therapy for patients suspected of sepsis, when every hour counts.
