BREA, Calif., Aug. 5, 2020 /PRNewswire/ -- Beckman Coulter today announced new analysis from the pivotal study of its novel monocyte distribution width (MDW) hematologic biomarker for sepsis detection. The analysis showed that abnormal MDW values, when considered along with the standard physiologic parameters at the time of patient presentation in the emergency department, signifies a four- to six-times higher probability of sepsis diagnosis. The pivotal study enrolled 2,158 Emergency Department patients in three leading academic centers and was a basis for FDA clearance of Beckman Coulter's Early Sepsis Indicator.

The analysis was recently published in the Journal of Intensive Care titled, "Monocyte distribution width enhances early sepsis detection in the emergency department beyond SIRS and qSOFA".

"We took a unique approach to the study and analyzed the results from the perspective of the front-line Emergency Department physicians and staff, whose job it is to quickly assess whether the patient is septic, or at risk of turning septic, and initiate treatment," said Elliott Crouser, M.D., professor of Critical Care Medicine at Ohio State University Wexler Medical Center and principal investigator in the study. "The value of MDW is that it provides physicians with an earlier indication of sepsis during the initial encounter, which is especially important when a patient's symptoms are mild and alternative diagnoses are being considered."

SIRS and qSOFA risk scores are routinely used for assessing the risk of sepsis based on the standard physiologic parameters such as body temperature, respiration rate, heart rate, blood pressure, and altered mental status, among others. Both were initially derived for use in the Critical Care environment and may lack sensitivity and specificity in Emergency Department patients. The study found that the routine use of MDW in conjunction with the scores, brings an appreciable diagnostic benefit.

"In the Emergency Department, we are trained to focus on the most life-threatening conditions first — like MIs, strokes and now COVID-19. Although deadly, early symptoms of sepsis can be very subtle," said Tiffany Osborn, M.D., professor of Surgery and Emergency Medicine at Washington University. "Having an ancillary test as a part of our standard CBC workup that adds early, diagnostic value to traditional clinical acumen is very helpful."

Researchers conducting the study also proposed the clinical role of MDW to supplement current clinical parameters used to screen for sepsis. In essence, this could potentially serve as a fifth SIRS criteria or a fourth qSOFA criteria, to enhance the early detection of sepsis in the Emergency Department^*.

The novel MDW hematologic biomarker (or Early Sepsis Indicator) is available on the Beckman Coulter DxH 900 and DxH 690T hematology analyzers as a part of a CBC with Differential.
