NTT DATA Corporation (Head Office: Koto-ku, Tokyo, Japan; President and Chief Executive Officer: Toshio Iwamoto; hereinafter, “NTT DATA”) and NIPPON TELEGRAPH AND TELEPHONE CORPORATION (Head Office: Chiyoda-ku, Tokyo, Japan; President and Chief Executive Officer: Hiroo Unoura; hereinafter, “NTT”) are recruiting insurance companies that agree to a free trial to demonstrate the effectiveness of NTT's lifestyle disease risk prediction technology (*1) in insurance companies' product development, member joining assessments, post-joining health improvements, and so forth. The aim of NTT DATA and NTT is to utilize this technology, a part of NTT's AI-related technologies (corevo® (*2)), in the insurance industry.
Currently, various efforts toward prevention and health promotion are being carried out in Japan with the intention of extending the country's healthy life expectancy. Lifestyle diseases in particular have become a social problem that leads to such issues as increased medical costs and lower employee productivity at companies. In order to prevent these diseases, there is a need to improve the lifestyle habits and grasp the health risks of individuals.
Accordingly, NTT has established, as a part of its AI-related technologies (corevo®), a method that makes it possible to conduct highly precise analyses, even with uneven or scarce data. The company has realized a way to predict the probability of developing a lifestyle disease in the future based on data acquired from health examinations (hereinafter, “health examination data”).
Insurance companies need calculations regarding future disease risks for health improvements and other purposes. By utilizing this disease risk prediction technology, insurance companies will no longer need to acquire and analyze large quantities of health examination data and medical receipt data, nor to deal with personal information requiring special consideration, as stipulated in the Amended Act on the Protection of Personal Information (*3). It is predicted that this technology will become vital as the insurance industry utilizes medical and health data to an even greater degree in the future.
With the analysis of health examination data, there are cases of data omissions when patients do not continue to receive examinations, cases of data for limited periods when only examination results from a certain period are retained, and cases of scarce sample data when diseases with few outbreaks are handled. In such cases, it has been difficult to analyze data with a high degree of precision.
To address this, NTT Service Evolution Laboratories and NTT Communication Science Laboratories have carried out ranking learning (refer to Figure 1) that also uses data from individuals who have not developed a disease, which is retained for only a short period, in order to achieve highly precise analyses even with uneven or scarce data. In this way, the laboratories has realized a technology that predicts the risk of lifestyle diseases (diabetes, hypertension, and dyslipidemia) based on health examination data (refer to Figure 2). This disease risk prediction technology has been applied to the health examination data analysis business at a portion of the organizations using Health Data Bank® (*4), provided by NTT DATA (approximately 100,000 individuals for up to six years). It has been verified that highly precise predictions are able to be obtained (*5).
NTT DATA will provide an environment for testing the disease risk prediction technology. The effectiveness of the prediction technology will be tested with multiple insurance companies who request testing.
Applications from insurance companies will be accepted until the end of June, 2018. After the applications have been received, the insurance companies and NTT DATA will adjust the testing plans, NTT DATA will be entrusted with the testing data prepared by the insurance companies, the prediction technology will be applied, and the prediction results will be returned to the insurance companies. Based on the prediction results, the effectiveness of the technology, the challenges for introducing that technology, and so forth will be tested together with the insurance companies.
NTT and NTT DATA are conducting research on not only the prediction of lifestyle disease risks, but also the prevention of increased severity after diabetes has developed. Concerning disease risk prediction as well, based on this trial's results and the needs that are present, the companies plan to accelerate their research with the aim of targeting more diseases. NTT and NTT DATA will combine their technologies and aim to commence services for insurance companies within FY 2018. They plan to conduct service expansions following the start of the service as well.
The NTT Group will fuse the cutting edge technologies of its research institutes with the information and communication technologies of its companies, seek to create businesses that support the health of citizens, and promote the activities of such businesses.
