Digital Cough Monitoring - A Potential Predictive Acoustic Biomarker Of Clinical Outcomes in Hospitalized COVID-19 Patients


According to this multi-center study results, patients hospitalized with COVID-19 who coughed 3.4 times per hour or less based on digital cough monitoring faced a greater risk for intubation or death.

This multi-site study investigates the potential of digital cough sounds as predictive biomarkers for clinical outcomes in hospitalized COVID-19 patients. It aims to determine if the acoustic properties of coughs can predict the severity and progression of the disease.

Methodology: The authors utilized digital cough recordings from hospitalized COVID-19 patients using Hyfe's cough detection and monitoring platform. Advanced acoustic analysis techniques were applied to these recordings to identify specific characteristics or patterns associated with different clinical outcomes.

Key Findings:

  1. Cough Acoustics and Disease Severity: The study found significant correlations between certain acoustic features of coughs and the severity of COVID-19. This implies that the way a patient coughs could indicate how severely they are affected by the virus.
  2. Predictive Value: The acoustic analysis of coughs proved to be a useful tool in predicting the clinical outcomes of patients. It could potentially be used to forecast the need for intensive care or the likelihood of recovery without intensive interventions.
  3. Non-Invasive Monitoring: The use of cough sounds as biomarkers provides a non-invasive method to monitor the progression of COVID-19 in patients, which is less resource-intensive and more comfortable for patients compared to traditional monitoring methods.

Implications for Healthcare:

  1. Early Intervention: By predicting the course of the disease early on, healthcare providers could intervene more effectively, potentially improving patient outcomes.
  2. Resource Allocation: Hospitals could use this method to prioritize resources and care for those who are most at risk of severe outcomes.

The study concludes that digital cough monitoring holds promise as a non-invasive, efficient, and effective way to predict clinical outcomes in COVID-19 patients. This innovative approach could enhance patient management and treatment strategies in the ongoing fight against COVID-19.
