Automatic Contact Tracing for Outbreak Detection Using Hospital Electronic Medical Record Data

Abstract

Contact tracing is a well-known tool for public health professionals to trace and isolate contacts of known infectious persons. During a pandemic contact tracing is critical to ending an outbreak, but the volume of cases makes tracing difficult without adequate staffing tools. Hospitals equipped with electronic medical records can utilize these databases to automatically link cases into possible transmission chains and surface potential new outbreaks. While this automatic contact tracing does not have the richness of contact tracing interviews, it does provide a way for health systems to highlight potential super-spreader events and support their local health departments. Additionally, these data provide insight into how a given infection is spreading locally. These insights can be used to inform policy at the local level.

“…Cone pursued a similar approach by developing a novel outbreak detection and case connection algorithm [5]. Linking connected cases with demographic analysis at granular community levels allowed the mobile clinic teams to target outreach for testing and vaccination deployments.…”
