Stay up to date on the latest in health tech, digital health and health AI news with this weekly brief. This is news from the week of May 4 to May 8. Tether launches medical AI that runs on phones, wearables Tether unveiled QVAC MedPsy Thursday, a new class of language models that can run directly on smartphones, wearables and other devices. The company says the platform’s focus on efficiency reduces both compute requirements and reliance on remote cloud infrastructure. Tether CEO Paolo Ardoino said in a statement that the launch was focused on “improving efficiency at the model level” instead of “scaling up size,” adding that the 1.7 billion-parameter model “outperformed larger systems” during testing. “That combination matters because it directly reduces compute requirements, latency and cost,” Ardoino said. “It allows the model to run locally on standard hardware instead of relying on remote infrastructure. In healthcare, that changes the constraints entirely; you can run medical reasoning where the data already exists, inside a hospital system or on a device, without moving sensitive information through the cloud or waiting on external processing.” Elation Health integrates new cardiovascular risk standard Elation Health announced Thursday it has licensed the American Heart Association’s Predicting Risk of Cardiovascular Disease Events (PREVENT) risk calculator to be embedded within its AI-powered clinical decision support tool. Elation’s Clinical Insights platform, powered by Anthropic’s Claude for Healthcare, ran more than 2,000 tests to ensure the implementation matches management guidelines. The American Heart Association and American College of Cardiology released updated cholesterol and lipid management guidelines in March, which made the PREVENT calculator the primary prevention test for atherosclerotic cardiovascular disease (ASCVD). “Primary care clinicians are on the front lines of prevention. Medicine moves fast, and when new clinical guidelines come out, they need technology that responds right
