Haifa’s Rambam Hospital is set to trial speech-based analysis technology by Israeli company Cordio Medical to remotely monitor and diagnose the status of COVID-19 patients based on samples obtained via a smartphone app.
The Or Yehuda-based Cordio Medical developed the HearO technology to monitor patients suffering from heart failure and the platform could prove useful for the sophisticated management of COVID-19 patients who have received a diagnosis and are in isolation but have yet to be hospitalized, the hospital said.
HearO analyzes recordings of a patient’s speech and can sense fluid accumulation and forewarn of an anticipated deterioration, the company says, adding that the tech has already been proven in clinical trials at 10 medical institutions in Israel including Rambam, the Beilinson-Rabin Medical Center, and Barzilai Hospital. The system provided a pre-deterioration notice on an average of ten days prior to an acute heart failure hospitalization with an accuracy rate of over 80 percent, Cordio says. The HearO system is in the process of seeking FDA approval as a means to monitor heart-failure patients.
Cordio’s solution for COVID-19 patients is based on adapting HearO to the deterioration process associated with the disease characterized by bilateral pneumonia with edema in the lungs. The system would pick up on a deterioration based on slight changes in lung fluids and the onset of inflammation before the patient can feel it, Cordio explained.
The system will also be used for remotely monitoring patients who have recovered and are at home.
The trial will monitor “5,000 patients ongoing in all stages: isolated (no symptoms), mild, moderate and severe conditions,” for 18 months, Cordio Medical CEO Tamir Tal tells NoCamels via email.
Cordio is concentrating on the lung disease-related symptoms that are not easily trackable. Currently, all other symptoms are easily discovered — for example cough and fever, Tal tells NoCamels
The system works by establishing a baseline for each patient after which they will record their voices daily “and we analyze it in our cloud-based system. Each day the system is not alerting, the baseline is adapting and adjusting utilizing the new info,” he says.
Tal explains that if successful, the HearO system will be able to alert the medical team about the start of a lung condition 10-48 hours before the patient’s condition becomes moderate or severe due to the infection.
As of April 1, Israel has over 6,000 confirmed cases of COVID-19, including over 200 recoveries and 25 deaths. Most of those diagnosed with the disease are in isolation at home or in hotels with a minority in hospital.
