An evaluation of machine learning to identify bacteraemia in SIRS patients

A team of researchers at the Medical University of Vienna has recently evaluated the effectiveness of machine learning strategies to identify bacteremia in patients affected by systemic inflammatory response syndrome (SIRS). Their study, published in Scientific Reports, gathered discouraging results, as machine learning methods could not achieve better accuracy than current diagnostic techniques. Bacteraemia is a frequent medical condition characterized by the presence of bacteria in the blood, with a mortality rate ranging between 13 percent and 21 percent. Past research suggests that a number of factors are associated with the risk of developing this condition, including advanced age, urinary or indwelling vascular catheter, chemotherapy, and immunosuppressive therapies.
