Representation of Unstructured Data Across Common Data Models

    Basic Details
    Date Posted

    A critical step in building the Sentinel network is to establish the organizational framework for expanding access to electronic health record (EHR) data. This includes structured data, particularly domains not found in administrative claims, such as laboratory results and inpatient medication administrations, as well as information derived from unstructured data such as free-text clinical notes. Unstructured data are of particular interest as they often include information that is not captured in any other source.

    The goal of this project is to guide the Sentinel network on how best to incorporate information derived from unstructured data into a Common Data Model (CDM) framework. This project has three objectives: 

    • Identify priority elements that should be derived from unstructured data 
    • Assess the overall availability of the priority elements among potential data partners
    • Provide recommendations as to how those priority elements should be represented in the Sentinel Common Data Model (SCDM)
