Artificial intelligence (AI) has the potential to revolutionize neurocritical care (NCC) by enabling precision management of brain injury patients. However, barriers such as data standardization, annotation, and device connectivity hinder its widespread adoption. With funding from the U.S. Department of Defense, we developed a standardized data infrastructure to make NCC data AI-ready. Our work focused on data integration, harmonization, standardized formats, and a user-friendly analytics dashboard. We established cloud connectivity for data uploads, developed an ontology for structured knowledge, standardized annotations, and converted data into HDF5 format with an API for access. A web-based dashboard was created for data visualization and interoperability. These tools have been successfully validated in clinical trials and AI-based seizure detection studies. Our efforts lay the groundwork for real-time, continuous precision management of brain-injured patients.
