R&D Study to Evaluate Cordio’s Usability and to Collect Patient Speech Utterances


To determine the usability and technical aspects of Cordio HearO™

Full Title of Study: “An Observational, Retrospective, Single-arm, Open US and Israel Study , for Usability Assessment and Algorithm, Development of the Cordio HearO™ Systeam”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: September 30, 2023

Detailed Description

The system (including App and server) will be tested under simulated use conditions with representative users to identify potential changes required to the application user interface, to improve user performance and satisfaction, and to inform future design options. The recordings data will also be used for algorithm improvement


  • Device: Cordio HearO
    • Cordio HearO is a software medical device that remotely monitors Congestive Heart Failure (CHF) patients by detecting changes in the patients’ recorded voice relative to a baseline. The system is comprised of a mobile application (or “app”) that is deployed on a mobile platform, and a web-based portal that enables caregivers to manage their patients

Clinical Trial Outcome Measures

Primary Measures

  • Patient Usability success defined as: 1.Total and individual usability score of ≥3 in the usability questionnaire in ≥80% of the users.
    • Time Frame: 2 years
    • The used scale is: Usability questionnaire for the Cordio HearO™ App. This Usability questionnaire is a subjective evaluation based on Likert score of device user satisfaction. Maximum value for each item: 5 Minimum value for each item: 1 Higher scores means a better outcome
  • Patient Usability success defined as: 2. Total Compliance
    • Time Frame: 2 Years
    • The total compliance will be determined by the total number of recording days. Success will be considered if total average compliance of 70 % of all days.
