How do clinical care teams remotely detect deterioration in COPD patients?

Patients hospitalized after a COPD exacerbation are at increased risk of readmission after discharge, with a 20% risk after 30 days and 40% after one year.

Up to 55% of readmissions after a COPD hospitalization may be preventable1:

  • COPD is one of three voice-affecting diseases, along with heart failure and pneumonia, that rank among the top five causes of 30-day readmissions.
  • COPD places a significant burden on patients and healthcare systems. 2,3,4
  • Exacerbations account for a majority of hospital admissions for COPD patients. 5,6

Our Solution: VocalisTrack - a CE-marked Voice Platform to Detect Shortness of Breath

VocalisTrack enables chronic patients to be tracked at home using voice. It is a stand-alone, AI-based software tool that analyzes voice recordings of COPD patients who record their voice via an app on their own smartphone. Analyzing the data from this app, VocalisTrack offers the clinical care team ongoing insights about the patient’s current shortness of breath.
  • Uses patient’s smartphone without additional hardware or physical examination
  • Detects changes in patients' shortness of breath
  • Bridges the gap between the patient and the healthcare system
  • Allows care team to potentially take clinical actions

VocalisTrack Whitepaper

COPD is a very common chronic disease, with 18 million diagnosed COPD patients in the US alone*. In Europe, the prevalence of COPD varies from 4-10% of the adult population.**

VocalisTrack provides potential to detect dyspnea remotely and provide proactive, preventive medical care.
