Wait-time-saving analysis and clinical effectiveness of Computer-Aided Triage and Notification (CADt) devices based on queueing theory

In person: 21 February 2022 • 11:30 AM - 11:50 AM PST

Abstract

A Computer-Aided Triage and Notification (CADt) device uses artificial intelligence (AI) to prioritize radiological medical images and speed up reviews of diseased cases in life-threatening conditions such as stroke, intercranial hemorrhage, and pneumothorax. However, questions remain on a quantitative assessment of the clinical effectiveness of CADt devices for speeding the review of patients with life-threatening conditions. This work presents an analytical method based on queueing theory to quantify the wait-time-savings and to study the impacts of CADt for various clinical settings. Our work has shown that the theoretical results are consistent with clinical intuition and are verified by Monte Carlo.
