Development of a Secure Personal Health Record System to Enhance Medical Data Interoperability

Healthcare providers face significant information gaps due to lack of interoperability between systems, with approximately 32% of patients experiencing issues in data exchange and about 5% rescheduling appointments due to missing prior data. This results in decreased healthcare quality and patient-centric care, highlighting the need for a unified, secure, and interoperable health record platform.

A mid-sized healthcare organization seeking to improve patient data management and interoperability across multiple healthcare providers and systems.

• Design and develop a web-based personal health record system that consolidates medical data, treatment history, and healthcare activities into a single accessible platform for patients and providers.
• Implement secure authentication mechanisms, including integration with popular identity providers, to ensure authorized and compliant access to sensitive health data.
• Enable seamless data sharing and interoperability with existing healthcare providers' systems through standards such as HL7 FHIR.
• Incorporate features for managing medical measurements, care plans, healthcare goals, and appointment scheduling to improve patient engagement and care coordination.
• Support integrations with wearable devices and health apps for real-time health data retrieval and management.
• Ensure compliance with relevant security and data standards, including ISO 27001, NEN 7510, and healthcare certifications, for safeguarding sensitive patient information.
• Optimize development and deployment efficiency using modern CI/CD practices.

• Secure user authentication through social login options and national eID solutions (e.g., Google, Digital Identity), with role-based access control.
• User network management allowing patients to invite family members and healthcare providers for collaborative care planning.
• Creation, management, and sharing of care plans, healthcare goals, and health tasks.
• Appointment booking and scheduling system integrated with healthcare providers' calendars.
• Medical measurements management including data from external devices and healthcare institutions, with retrieval and storage functionalities.
• Push notifications to alert users about upcoming appointments, new health data, or care plan updates.
• Standard-compliant data sharing with hospitals, pharmacies, and other healthcare entities via HL7 FHIR.
• Mobile and desktop responsive interfaces for ease of access and user engagement.

• Healthcare systems for medical records exchange via HL7 FHIR standards.
• Wearable health devices and mobile health apps such as health tracking platforms.
• Identity verification systems including social login providers and national eID (e.g., Dutch DIGID).
• Notification services for push alerts to users' devices.

• System scalability to handle increasing user base and concurrent data exchange with external healthcare systems.
• High availability with 99.9% uptime to ensure continuous patient access.
• Strong security measures compliant with standards like ISO 27001, NEN 7510, and data encryption protocols.
• Performance optimized to handle real-time data syncing and retrieval operations.
• Regulatory compliance with healthcare data protection laws and standards.

The proposed health record platform aims to significantly improve healthcare data interoperability and accuracy, reducing appointment rescheduling due to missing information by up to 20%. It will empower patients with greater control over their health data and facilitate timely, coordinated care among providers, ultimately enhancing healthcare quality and patient satisfaction.
