Objectives: The Ministry of Health initiated a landmark project aimed at establishing a comprehensive national-level Medical Data Exchange Bus (MDEB) and a centralized medical data warehouse. The integration of all Electronic Health Record (EHR) systems across the country through MDEB was mandated to adhere to the universal Fast Healthcare Interoperability Resources (FHIR) specification (https://www.hl7.org/fhir/overview.html). Our company was tasked by the one of state authority overseeing EHR implementation to seamlessly integrate their system with MDEB, ensuring bidirectional data exchange in alignment with project requirements.
Solution: In the preliminary stages, we collaborated closely with the company-developer of MDEB and the data warehouse to gain a comprehensive understanding of both technical and non-technical requirements. A meticulously crafted project plan was developed, aligning with the overarching implementation strategy of MDEB and the data warehouse. Special emphasis was placed on defining triggering events for data exchange, eliciting exchanged data sets, and delineating actions in compliance with the business rules utilized within our client’s EHR.
A suite of applications was engineered to fulfill all requirements for seamless data exchange:
- Integration Component: This component offers a user-friendly interface for administrators, facilitating:
- Configuration of triggering events
- Mapping of EHR and FHIR resources
- Endpoint connection configurations
- Establishment of subscriptions for EHR events
- Event Monitoring: Detailed tracking of data exchange events, including status (in progress, success, or error), exchanged resources (data objects), and the complete path of data transformation and transfer to and from MDEB.
- Monitoring functionality to ensure the availability of MDEB and other components of the medical data exchange platform.
- Advanced Security and User Management: Implementation of robust security measures, including two-factor authentication, role-based access control, and efficient user management capabilities for administrators.
- “Who is Online” Feature: Enables administrators to effortlessly identify and monitor active users, fostering real-time collaboration and oversight.
2. Processing Component: This component ensures seamless conversion of data between FHIR and EHR objects, processing data according to predefined algorithms and business rules set within the Integration application. The Processing app operates background jobs, automatically executing actions based on specified business rules and conditions.
Presently, our Medical Data Exchange platform efficiently facilitates the exchange of data as required. The launch of the MDEB, data warehouse, and Medical Data Exchange platform is anticipated to occur in the middle of summer 2024.
