Health data- and model- driven Knowledge Acquisition (HeKA)
Hospital information systems are used at every step of patient care, collecting continuously longitudinal data, both unstructured and structured, including clinical reports, drug prescriptions, laboratory results and omics data. Unfortunately, the knowledge that can be acquired from previously collected health data is hardly considered in the clinical care of new patients.
The objective of our Inserm team is to develop methodologies, tools and their applications in clinics towards a learning health system, i.e., a health system that leverages clinical data collected to extract agilely and reliably novel medical knowledge that, in turn, continuously improves healthcare. We rely on the availability of EHRs (Electronic Health Records), clinical trials, cohorts and other linked data to develop models for stratification and prediction with the potential of improving the precision and the personalization of treatments, and in turn the quality of healthcare.
With this objective, the team 22 research activity follows 3 interdependent axes: (1) Patient phenotyping and representation learning, (2) Stochastic and data-driven predictive models for decision guiding, and (3) Designs of next generation clinical trials.
