Research Summary

Randall Wetzel, MD, has been awarded a Challenge Grant in Health and Science Research by the National Institutes of Health (NIH) National Library of Medicine to research advanced computational frameworks for decision support in critically ill children. The study aims to provide information for patient management by providing outcomes data on previous patients with similar diagnosis and symptoms.Researchers are using advanced computational techniques and artificial intelligence to detect categories in raw medical data from disparate data sources, allowing the most recent information about large numbers of critically ill children to be data mined. This enables researchers to find similarities between a patient and historical populations with known outcomes to provide decision support for diagnosis, management and therapy, while aiding disease detection, directing patient care, and ensuring quality and safety.
