A Multicenter Randomized Trial of CT-Based AI Decision Support for Early Pneumonia Care

Adults hospitalized with pneumonia who need new or increased oxygen support or have defined immunocompromise will be assigned to usual care with or without access to a CT-based AI report. The report summarizes likely pathogen classes, lung involvement, and short-term deterioration risk. Clinicians review the report alongside images and clinical evidence and retain responsibility for testing and treatment. The trial asks whether AI-assisted care reduces death or new invasive respiratory or circulatory support within 28 days. Patients are followed after discharge through day 90.
