Public health monitoring and research: experience with electronic health record data

Abstract

This talk will describe the software underlying CHORDS, the concept of a federated query, the methods CHORDS uses to enable site participation, and the formal agreements required to contribute to the network or query distributed data. Finally, we will discuss growth of this technology platform and anticipated needs and challenges as CHORDS serves new use cases to enable clinical health research studies and other research activities. A key challenge is the need for patient record linkage to unduplicate an individual’s medical records across systems. A solution underway seeks to transfer data to an external partner to leverage an existing master patient index tool used for clinical care.
