Project Summary/Abstract
Nearly one million Americans suffer from a stroke every year, often resulting in serious long-term disability or
death. Early detection and treatment of stroke is critical to improving patient outcomes. Several tools have
previously been developed that attempt to screen and help identify patients having a stroke, but there are still
many stroke cases that are missed, even after the patient arrives to the emergency room.
This study aims to improve the identification and triage of stroke patients in emergency departments using
artificial intelligence (AI) on multimedia patient data. Our hypothesis is that real-time, standardized, and
reproducible stroke assessment tools using AI can improve stroke triage and decrease missed diagnoses in
patients with minor-to-moderate neurological symptoms. The study plans to develop a DeepStroke+
augmented-intelligence framework to triage any kind of strokes (ischemic stroke, hemorrhagic stroke, transient
ischemic attack, etc) versus stroke mimics commonly seen in emergency settings. We developed a
DeepStroke+ framework for stroke triage using facial videos of English-speaking patients who are describing
the “Cookie Theft” picture from the Boston Diagnostic Aphasia Examination. Based on this technology, we will
develop a stroke triage app and validate it in different triage scenarios from mobile stroke units to emergency
room triage in local and telestroke scenarios.
Public Health Relevance Statement
Project Narrative
The proposed use of DeepStroke+ in this study aims to improve the identification and triage of stroke patients
in emergency departments, with the goal of alleviating some of the burden on emergency room doctors in the
United States. By using artificial intelligence (AI) to identify stroke patients quickly and accurately, medical
personnel may be able to mobilize a stroke team and reduce the time to complete a physician evaluation for
patients who arrive to the emergency room with treatable strokes. AI tools could help to streamline the triage
process from mobile stroke units to hospital emergency rooms and potentially reduce the number of patients
that mistakenly identified as acute stroke and reduce the operating cost of mobile stroke units. Additionally,
they can be used 24/7 and may help to bridge the gap when there is a shortage of specialists in remote
emergency room.

Publications
Publications are associated with projects, but cannot be identified with any particular year of the project or fiscal year of funding. This is due to the continuous and cumulative nature of knowledge generation across the life of a project and the sometimes long and variable publishing timeline. Similarly, for multi-component projects, publications are associated with the parent core project and not with individual sub-projects.
