Integrated Sepsis Surveillance Algorithms

We are currently working on an intelligent sepsis monitoring system to continuously identify and risk stratify patients at increased risk of sepsis. We are working with leading experts in machine learning at the Courant Institute of Mathematical Sciences to develop the machine learning theory to integrate all available demographic, laboratory, radiographic, and continuous hemodynamic data. We will use these algorithms to derive next generation clinical alerts, contextual information retrieval, and targeted decision support. This research is supported by a CIMIT Innovation Grant funded by the Department of Defense. clinical trials protocol
