Preserving Individual and Institutional Privacy in Distributed Regression Models

Dept. of Computer Science (April 9, 2014)

SEMINAR SERIES : Distinguished lecture

MAJOR SPEAKER : Ohno-Machado, Lucila
LENGTH : 68 min.
ACCESS : Open to all
SUMMARY : Building predictive models using clinical and molecular data requires a large number of observations. The wide adoption of electronic health records in the USA allows the collection of data about a large number of patients. Learning healthcare systems are built from federated networks of clinical data warehouses. Their goal is to build data-driven models that improve patient outcomes. These models usually require adjustment for confounders such as co-morbidities and demographics. Distributed multivariate models help promote privacy by allowing data to remain at their origin and aggregating calculations made locally. I will describe methods and tools we have developed to perform privacy-preserving distributed computing on clinical data warehouses at the University of California San Diego and collaborating institutions.  [Go to the full record in the library's catalogue]
