Framework for Improving Patient Safety: Reference Model for FHIR-Enabled, Patient-Centric Home Medication List...

Area of Science:

• Health Informatics
• Clinical Informatics
• Patient Safety

Background:

• Home medication list reconciliation is a key area for improving patient safety and reducing clinician workload.
• Current systems often lack interoperability, hindering efficient medication management.

Purpose of the Study:

• To develop a platform-neutral, FHIR-enabled reference model for patient-centric home medication list management.
• To create a demonstration wireframe showcasing interoperable medication list reconciliation.

Main Methods:

• Developed a reference model with conceptual and data architecture artifacts.
• Created a high-fidelity wireframe using JavaScript, Bootstrap Studio, and FHIR.
• Integrated RxNorm content and FHIR calls to an EHR sandbox for standardized data access.

Main Results:

• The reference model positions the patient at the center of medication management.
• The wireframe demonstrates FHIR's capability for data interoperability and reduced burden.
• Generated FHIR patient-reconciled medication lists and printable versions for clinical use.

Conclusions:

• FHIR shows significant potential for patient-facing medication list management.
• The developed framework serves as a reference for future development in interoperable health data systems.
