Arteryex Launches Initiative to Utilize Medical Information through PHR Data and AI

Arteryex Co., Ltd. (headquartered in Chiyoda City, Tokyo; CEO: Dongying Li) has launched a new initiative combining personal health record (PHR) data held by individuals with artificial intelligence (AI) to support understanding, organizing, and utilizing medical information.

As part of this initiative, the company has updated and released an "AI Consultation Function" within its medical information management app "Pashakarte." This new feature assists users in understanding and organizing their medical information—such as health check results, test results, and medication details—that they have registered in the app. The feature is currently available to Premium Plan and Family Max Plan members.

PHR data includes important medical and health information such as health check results, test results, medication records, and daily health logs. However, merely recording and storing this data is insufficient to fully realize its value. There remain challenges in understanding the content and effectively using it for daily health management and communication with healthcare providers.

In addition to delivering value directly to individuals, this initiative will also explore future possibilities for utilizing PHR data in collaboration with pharmaceutical companies, healthcare organizations, nursing and medical care providers, home healthcare services, and research institutions. Any use of PHR data will be based on individual consent, proper governance, and robust security measures.

Arteryex aims to realize its "Health Bank" vision—where individuals manage their own medical data and return its value to themselves, patients, and society. By advancing PHR from mere "recording" to active "utilization," the company will continue promoting patient-centered medical data usage.

Background: Challenges in PHR Data Remaining Only as Records

In recent years, the importance of PHR—where individuals manage their own medical and health information such as health check results, test results, medication records, and daily health logs—has been growing.

However, PHR data often remains underutilized, limited only to recording and storage.

Health and test results contain numerous values and specialized terms, while medication information—including drug names, dosages, timing, and prescription history—is critical but not always easy for individuals to fully understand and apply in daily life.

Additionally, when visiting healthcare providers, individuals may struggle to clearly communicate their concerns or fail to adequately organize past test results and medication history.

To maximize the value of PHR, it is essential to move beyond mere recording and support individuals in understanding, organizing, and actively using their health data when needed.

Goals of Combining PHR Data with AI

This initiative does not aim to have AI replace doctors in diagnosis or treatment decisions.

Instead, it seeks to support individuals by helping them understand their medical information, organize concerns, and prepare for consultations with healthcare providers—using their own PHR data in combination with AI.

By integrating PHR data and AI, the following value propositions become possible:

- Support in understanding health check and test results

- Organizing medication and past medical records

- Preparing key points to discuss with physicians before appointments

- Supporting communication with healthcare providers

- Organizing health information for family members

- Assisting individuals in actively using their own medical data

PHR data is valuable personal medical information. By leveraging AI, Arteryex aims to shift PHR from passive "recording" to active "utilization."

AI Consultation Function in the Medical Information Management App "Pashakarte"

As a concrete implementation of this initiative, Arteryex has updated and released the "AI Consultation Function" in its medical information management app "Pashakarte."

This function supports users in understanding and organizing their medical information—such as health check results, test results, and medication records—registered within the app.

The feature is currently available to Premium Plan and Family Max Plan members. By monitoring user adoption patterns and feedback, Arteryex will continue to explore the potential of PHR data combined with AI.

Potential Applications in Pharmaceuticals, Healthcare, Medical Care, and Research

The use of PHR data combined with AI extends beyond individual users. Arteryex believes this approach holds potential for collaboration with pharmaceutical companies, healthcare providers, nursing and medical care services, home healthcare, and research institutions, and will continue engaging with these sectors.

Potential applications include:

- Supporting patient education and information delivery

- Assisting in understanding patient insights

- Supporting pre-visit information organization

- Enhancing communication between patients and healthcare providers

- Supporting information organization in home healthcare and nursing care

- Enabling patient-centered medical data use in research

- Exploring integration with healthcare services

These initiatives will not involve the casual use of personal or sensitive medical information. All efforts will be based on individual consent, appropriate governance, security measures, anonymization, and aggregation, ensuring responsible, patient-centered use of medical data.

Approach to Consent, Governance, and Security

PHR data is highly sensitive and important to individuals.

Arteryex places strong emphasis on user consent, proper governance, and data security in any use of PHR data.

This initiative will comply with the company's internal policies based on its ISMS certification, Terms of Service, and Privacy Policy, ensuring appropriate handling of PHR data.

When exploring collaborations with pharmaceutical companies, healthcare providers, nursing care services, home healthcare, or research institutions, Arteryex will always require individual consent and use only aggregated or anonymized data under appropriate management controls.

Connection to the Health Bank Vision

Arteryex promotes the "Health Bank" vision—empowering individuals to manage their medical data and return its value to themselves, patients, and society.

PHR data is not merely stored information.

It is information that helps individuals understand their health, communicate more effectively with healthcare providers, and—when consented and properly managed—can contribute to society and research.

This initiative marks a significant step toward realizing the Health Bank vision by advancing PHR from "recording" to "utilization" and further returning its value to individuals, patients, and society.
