Magnolia Medical Technologies, Inc., inventors of Steripath, an FDA 510(k)-cleared device platform indicated to reduce blood culture contamination1 for sepsis testing, announces the commercial availability of its new Steripath Micro Initial Specimen Diversion Device designed for children’s hospitals. Use of the new Steripath Micro device in two children’s hospitals has shown a zero percent contamination rate over the last three months.
“Working with children’s hospitals across the country, we are excited to launch Steripath Micro, the first technology solution specifically designed to reduce blood culture contamination for our most vulnerable patient populations,” says Greg Bullington, CEO and co-founder of Magnolia Medical. “We are proud of the exhaustive clinical results we have generated with our Steripath platform proving that false positive blood culture results used to diagnose sepsis can be eliminated with our technology. It’s very encouraging to see a zero percent contamination rate demonstrated with our new Steripath Micro device.”
Blood cultures are an essential diagnostic tool and remain the standard of care for detecting microorganisms in a patient’s bloodstream.2,3 As one of the most critical microbiology tests, blood cultures are used to confirm or rule out life-threatening bloodstream infections, including sepsis, and provide necessary information to optimize treatment.
Despite the clinical importance, false positive results are common. Historically, the testing process has not accounted for the realities of dislodged skin plugs and fragments containing viable microorganisms from venipuncture. Consequently, 30% to over 50% of blood cultures can be contaminated, producing a false-positive test result.4 These false-positive results trigger risk of overuse of toxic antibiotics, re-tests, delayed appropriate treatment, additional interventions, extended hospital stays, and higher costs for the patient and the hospital.2 The associated cost of a contamination event at a children’s hospital has been reported as a median of $8,720.5 In addition, false positives can contribute to resistant bacterial strains, long-term societal effects, and increased healthcare burden and costs.6
“We are encouraged by the early results we’ve seen so far in the reduction of blood culture contaminants since using the Steripath Micro device and we’re eager to see more data over the next several months ,” said Rick Place, MD, pediatric medical director, Department of Emergency Medicine at Inova Fairfax Hospital for Children.
Steripath Micro is FDA 510(k)-cleared with the specific indication to reduce blood culture contamination.1 For children’s hospitals, this means that patients with suspected bloodstream infections, such as sepsis, can now receive an accurate diagnosis, enabling precise and timely treatment. Steripath Micro is a small, lightweight, easy-to-use device that can standardize the blood culture collection process, providing immediate and sustainable reduction in contamination rates which can improve patient outcomes and decrease healthcare burden from sepsis misdiagnoses.
