A stepped-wedge trial covering 59,980 emergency department presentations for possible myocardial infarction found that point-of-care high-sensitivity troponin testing cut length of stay by 13% with unchanged 30-day safety, according to a report in Circulation. Microsoft's MAI-DxO reached 80.3% diagnostic accuracy versus 46.8% for physicians on emergency department cases in a Science study, and a simulation trial found a feedback device improved pediatric bag-mask ventilation by emergency medical services (EMS) clinicians.
THE DETAILS
- Technology Oct 19, 2026A pragmatic, stepped-wedge cluster-randomized trial at six sites with 59,980 emergency department (ED) presentations for possible myocardial infarction compared whole-blood high-sensitivity cardiac troponin testing at the point of care with a central laboratory assay in an accelerated diagnostic pathway, in a report published Oct. 19 in Circulation. On the primary end point, ED length of stay, the intervention cut stays by 13% (95% CI 9% to 16%), a reduction of 47 minutes. Myocardial infarction or cardiac death within 30 days occurred in 0.39% of patients in each arm (P = .54), and the authors said point-of-care testing was safe.Source: Circulation
- AI Oct 22, 2026Microsoft's MAI-DxO system correctly diagnosed 83.2% of complex New England Journal of Medicine cases, compared with 36.1% for generalist physicians using search and reference tools and 22.3% without them, according to a study published Oct. 22 in Science. The physician comparison used a held-out set of 56 cases. On 325 emergency department admissions from the MIMIC-IV-ED dataset, it reached 80.3% accuracy versus 46.8% for physicians. The authors wrote that the text-only comparisons "do not establish superiority over specialists, multidisciplinary teams, or real-world clinical practice." All authors are Microsoft employees with equity, and Microsoft funded the research, Becker's Hospital Review reported.Sources: Microsoft AI, Becker's Hospital Review
- Technology Oct 20, 2026In a randomized crossover simulation study published Oct. 20 in Pediatrics, 123 participants from five emergency medical services (EMS) agencies across three metropolitan sites ventilated a simulated 3-year-old manikin with and without real-time feedback from a ventilation feedback device. With feedback, guideline-recommended tidal volumes were achieved in 87% of breaths compared with 16.2% without it, and ventilation rate adherence improved from 65% to 88.6%. The authors said EMS clinicians rarely met manual ventilation guidelines for pediatric patients in respiratory arrest.Source: Pediatrics
