A Standards-Based Architecture Proposal for Integrating Patient mHealth Apps to Electronic Health Record Systems

Area of Science:

• Health Informatics
• Digital Health
• Medical Technology Integration

Background:

• Mobile health applications (mHealth Apps) promote patient involvement in healthcare management.
• Current mHealth Apps often function as isolated systems, limiting data sharing with electronic health records (EHRs).

Purpose of the Study:

• To propose a standards-based architecture for mHealth Apps to exchange information with EHR systems.
• To facilitate better quality of care through improved data interoperability between mHealth and EHRs.

Main Methods:

• Designed a novel architecture for EHR/mHealth App integration based on defined requirements and current standards.
• Modeled a case study for home monitoring of congestive heart failure patients using the proposed architecture.
• Simulated the integration using OpenMRS (EHR) and the iOS platform (mHealth App).

Main Results:

• Developed an integration architecture based on bi-directional exchange of Clinical Document Architecture (CDA) Release 2 documents.
• Clinician prescriptions for home monitoring are sent to mHealth Apps, which generate monitoring calendars.
• mHealth Apps return structured, CDA2-compliant monitoring reports to the EHR, ensuring data integrity and avoiding local storage.

Conclusions:

• The proposed architecture facilitates bi-directional data exchange between patients and healthcare professionals.
• This integration represents a significant advancement in connecting mHealth Apps to the broader health-IT ecosystem.
• The architecture supports enhanced patient engagement in self-management and self-care.
