## Overview
WizWe Inc., in partnership with NTT Docomo Business Inc., has completed a demonstration project for 'MemoLink,' a cognitive support service on LINE. This project was part of the Ministry of Economy, Trade and Industry's initiative to promote service development for social problem-solving using advanced technology in the field of preventive health.
## Background and Objectives
With Japan's rapidly aging population, rising medical and nursing care costs, and declining productivity have become critical social issues. Leveraging PHR (Personal Health Record) data is increasingly vital for preventive healthcare. The pilot aimed to verify whether chat-based intervention can effectively promote the maintenance of cognitive function and the continuation of preventive behaviors among the elderly.
## Project Details
Based on PHR data from NTT Docomo Business's 'Kenko Mileage' platform, the project provided personalized support tailored to each participant's step counts, sleep data, and frailty scores. The service featured dedicated habit-building supporters delivering encouraging messages via LINE, alongside an AI consultation function ('AI Asada-sensei'). The project engaged 22 elderly participants across three environments: a cognitive specialty clinic, a fee-based support service, and a nursing care facility.
## Results
1. Behavior Retention: 86% retention rate for preventive activities (three or more days per week).
2. Psychological Impact: Average self-efficacy score of 7 out of 10, indicating strong confidence in continuing habits.
3. Business Potential: 100% intent to re-participate and 100% willingness to pay (at a suggested price point of 500-1,000 JPY per month).
4. Operational Value: Nursing staff reported improved ability to monitor participant status outside of scheduled care days, providing valuable data for personalized service plans.
## Future Prospects
Building on these results, WizWe aims to expand its collaboration with senior clubs, insurance companies, and local governments. The company is already simulating a model for senior clubs projected to reach 10,000 users, aiming for a swift social implementation.
