1 . As the COVID-19 pandemic continues, healthcare workers continue to risk their lives to treat patients. Under the current system, diagnosing, monitoring, and managing COVID-19 are contributing to its spread through contact. In an effort to improve this situation, data analytics company SDG Group has announced a new smartphone application called Docdot to help doctors collect relevant clinical data through telemonitoring.

Docdot uses facial recognition technology on smartphone cameras to detect a patient’s vita signs and process them using artificial intelligence. This recognition and processing technology (photoplethysmography) was developed by Binah. ai. It enables smartphone cameras to use the light reflected by blood vessels (血管) under the skin to detect and record changes in the volume of blood flowing in blood vessels under the skin, and that occur due to variations in respiration (呼 吸), blood pressure, etc. The app converts this into measurements reportedly 90 percent as accurate as hospital-grade monitors.

Docdot enables people to look into their smartphone’s screen and share early indicators of infection .It gives health workers the information they need to triage (分诊) patients at a safe distance, preventing unnecessary visits to hospitals and reducing the risk of exposure among health workers and patients. This maximizes the availability of healthcare resources for those who need them most, and contributes to slowing the spread of the virus.

“Use of this technology for virus monitoring and detection is new,” says Heather Beardmore, SDG Group UK chief executive. “This healthcare innovation is the first remote-monitoring and triage tool with potential to transform diagnosis and management.” It is also recognized by World Health Organization (WHO) and Forbes as being one of the most innovative digital health solutions worldwide. Docdot has undergone clinical trials in Canada India and Japan, and is now used in the USA hospitals.
