System and Method of Semantic Differentiation of Individuals Based On Electronic Medical Records

摘要

This document presents a system and method to extract highly meaningful terms from unstructured fields in an EMR that distinguish two different patient populations. Using this system, healthcare providers can quickly identify terms that are highly associated with a specific set of patients, for instance, chronic heart failure (CHF) patients who are high utilizers of the emergency department (ED) compared to CHF patients with low ED utilization. The system enables healthcare providers to identify root causes of health outcomes and to discover potential targets for intervention and improving healthcare delivery.
