The First Part: TechDoctor Moving Toward an Era Where Data Improves “Wellness”

Utilizing Daily Monitoring Data for Medical Care

Have you ever heard of the term “digital biomarker”?

A “biomarker” can indicate some disease or its progression and refers mainly to biologically derived data such as heart rate, blood pressure, electrocardiograms, and even proteins measured in the blood. Biomarker data also includes biochemical tests, various clinical test values such as tumor markers, and diagnostic imaging data*¹, and is used for a wide range of purposes, including diagnosis, disease course and therapeutic effect prediction, and mechanism of action of drugs.
　
“Digital biomarkers,” a type of biomarker, is an indicator that objectively visualizes disease status and changes due to treatment using data obtained from digital technologies such as AI, smartphones, and wearable devices. Digital technology enables the acquisition and analysis of data that cannot be obtained with conventional biomarkers and is expected to be utilized in daily medical care and drug research and development.

According to research by Emergen Research, the global digital biomarker market was US$1,013.9 million in 2020 and is estimated to reach US$14.44 billion by 2028, with a CAGR of 39.2% in revenue. Driving this revenue growth are the growing popularity of smartphones and wearables and the increasing number of users of health apps*², which will continue to contribute to the development of the digital biomarker market.

TechDoctor Inc (hereafter “TechDoctor”) aims to develop digital biomarkers, which are objective data indicators of diseases, using a large amount of long-term data and analytical techniques, and to link them to the provision of appropriate medical care. Under the mission of “Moving Towards an era where data improves ‘wellness’,” TechDoctor is developing two businesses: “SelfDoc.,” a wearable outpatient solution for psychiatry, and “SelfBase,” a wearable data analysis platform.

“SelfDoc.”
“SelfDoc.,” one of TechDoctor's services, is an online mental health solution that uses proprietary technology to analyze and share data to watch over the patients. Based on the data acquired from the wearable device, we visualize the condition of the body and mind and propose actions to improve one's “wellness.”

Today, one must control its mental health to cope with various changes. “SelfDoc.” quantifies the state of one’s body and mind on a given day based on four crucial factors for knowing one’s condition: feelings, heartbeat, sleep, and exercise. In addition, it can also be visualized on a weekly or monthly basis, allowing the user to understand when mental fluctuations occur. 

The “SelfDoc.” service has been provided mainly to companies in industrial health. This service will be offered to medical institutions, allowing objective data on patients’ exercise and sleep, which until now has been difficult for physicians to grasp accurately, to be shared between patients and physicians. In July 2021, we started a demonstration test at a clinic in Funabashi, Chiba Prefecture, to verify whether this will lead to better doctors' advice and an increased sense of security and satisfaction among patients.
