PROJECT OVERVIEW
HcDat spearheaded the implementation of Fast Healthcare Interoperability Resources (FHIR) for a major Health Information Exchange (HIE). The primary objective was to streamline the request, response, consumption, and distribution of millions of FHIR messages per hour using standardized formats and vocabulary. The project also addressed real-time firewall auditing and stringent HI-Trust security requirements, ensuring compliance while optimizing performance.
Challenge
The HIE faced challenges on multiple fronts, including:Application Layer: The HIE needed to maintain existing reporting and analysis systems while simultaneously converting data into FHIR, CDA, and CCD formats on-the-fly. This required inline validation to ensure data integrity across different formats and structures. Response Times: Due to varying workloads throughout the day and month, the system had to dynamically allocate resources to meet demand spikes without errors. Smooth decommissioning of resources during low activity periods was also essential to optimize costs. Security: Meeting HI-Trust security standards was paramount, requiring real-time penetration auditing and firewall hardening in a cloud environment. The solution had to ensure high data throughput while maintaining top-tier security standards.
Customer
A major Health Information Exchange (HIE) aiming to improve healthcare data interoperability, security, and efficiency while processing vast amounts of sensitive information in real-time.
Solution
HcDat implemented a customized solution using AIDBOX, a robust FHIR service, integrated with Rhapsody and Corepoint gateways on Azure Entra ID (previously called Azure AD). The solution was designed to address data transformation, security, and dynamic scaling needs. Key technologies included:Airflow DAGs: Enabled multi-threaded processes to boost request throughput. Trino: Provided memory scaling and resource scheduling of Kubernetes clusters.ISTIO and GLOO Mesh Enterprise: Implemented cluster access control and dynamic scaling, ensuring smooth resource allocation. Infrastructure as Code (IaC): Streamlined the development-to-deployment pipeline, using Docker images and Helm charts for rapid, reproducible environment setups.
Results
Implementation resulted in the following key outcomes: Enhanced Security: Real-time penetration auditing and compliance with HI-Trust standards ensured robust security throughout the cloud infrastructure. ISTIO’s auditing and enforcement of cluster access rules helped maintain a secure environment for data processing. Optimized Throughput: Airflow DAGs and Trino allowed intelligent multi-threading and dynamic memory scaling, boosting request and response times across fluctuating workloads. This ensured smooth, uninterrupted service during peak periods and resource decommissioning during off-hours. Cost Efficiency: Kubernetes clusters were scaled dynamically based on demand, reducing operational costs during lower traffic periods while maintaining high performance during peak times. The solution’s scalability and flexibility allowed the HIE to meet its benchmarks without compromising on efficiency or security. Empowered Client: The client’s staff received thorough training, ensuring they could manage day-to-day operations confidently. They continue to grow and expand, supported by a forward-looking tech integrator like HcDat, ready to tackle future challenges with cutting-edge technology.
