CoughMonitor Pilot Validation: Data Analysis and Presentation
Summary
This paper describes a pilot study aimed at quantifying the accuracy of AI enabled cough monitoring. We have established a rigorous methodology for evaluating and reporting results and claims to its performance, making us confident that the current version of Hyfe Cough Monitoring System will achieve clinically meaning
The Hyfe “CoughMonitor” is a wrist-worn device thatcaptures sound through its microphone and processesthat sound on device to detect and quantify coughingover time; the device ingests continuous audio andoutputs the timestamps of all of the coughs that itdetects. To assess the CoughMonitor’s accuracy, onemust compare its output (when the device reportsthat coughing occurred) with objective ground truth(when trained human annotators report that coughingoccurred). A perfectly accurate device would detectevery human annotated cough as such and would notidentify anything else as a cough.This paper describes a small pilot study aimed atquantifying the accuracy of an earlier version of theHyfe CoughMonitor and, in so doing, demonstrates theanalytical approach and data presentation that will beemployed in the subsequent FDA enabling study.
