Recently, the Concordia Critical Care Big Data and Artificial Intelligence R&D and Clinical Decision Support Seminar and Training Conference was successfully held. At the conference, a critical care clinical decision support system based on evidence-based medicine and intelligent analysis was released in the presence of many experts and thousands of participating doctors. The system has been jointly developed by the Concordia ICU, the Information Centre and DHCtech. It follows the standards proposed in the China Critical Care Primary Care Process and provides real-time multi-dimensional and intelligent clinical decision support based on a knowledge base of critical care medicine with Chinese characteristics. It meets the demands of primary care institutions for critical care diagnosis and treatment, and addresses the problems of standardized diagnosis and treatment and quality control management of critical illnesses in a targeted manner.
