EHR-PHR Linkage Platform for Managing Personalized Healthcare Processes Within Clinical Pathways

Area of Science:

• Health Informatics
• Clinical Informatics
• Public Health Policy

Background:

• Japan faces demographic challenges: an aging society and declining birthrate.
• There is a critical need to utilize health and medical information to extend healthy life expectancy and optimize social security.
• The Japanese government is actively promoting the integration of Electronic Health Records (EHR) and Personal Health Records (PHR) as a national strategy.

Purpose of the Study:

• To extend the application of OAT units from inpatient to outpatient clinical pathways.
• To integrate EHR/PHR platforms with personalized Learning Health Systems (LHS) for outpatient process management.
• To enable patient-specific management goals, evidence-based guidance, and early side effect detection in chronic disease care.

Main Methods:

• Development of a three-layered structure (Outcomes, Assessments, Tasks – OAT units) for standardizing clinical practice.
• Implementation of OAT units within outpatient clinical pathways.
• Integration of EHR/PHR platforms with personalized LHS for patient-specific management.

Main Results:

• The system enables patient-specific management goals determined in outpatient pathways and shared with patients.
• Provides evidence-based lifestyle guidance and facilitates early detection of treatment side effects.
• Facilitates bidirectional communication focusing on meaningful data exchange between healthcare providers and patient daily life information.

Conclusions:

• The developed system advances patient-centered care through personalized LHS in outpatient settings.
• Standardizing healthcare processes, including OAT units and ISO proposals, is crucial for personalized care.
• This approach supports the development of personalized LHS to address Japan's demographic and healthcare challenges.
