Research summary
Characterizing Secure Chat messaging patterns among providers who communicate within the Electronic Health Record.

My research focuses on characterizing the communication patterns among healthcare providers who utilize secure messaging within the electronic health record (EHR). These communication patterns are elucidated through EHR messaging metadata among several hospitals and outpatient clinics here at Washington University School of Medicine. By understand the local and global structures of the communication network, we aim to elucidate how providers utilize the secure chat messaging features and how it effects their communication behaviors. Additionally, we explore how these communication patterns effect downstream work behaviors within the EHR.
