A FHIR-Based Dashboard as an Integrated Research Patient Record and Quality Assurance Tool

Modern biomedical research requires the integration of heterogeneous clinical and research data across distributed systems. As part of Germany's Medical Informatics Initiative, Data Integration Centers have established FHIR repositories to support data-driven studies and federated research based on interoperability through the German National Core Dataset specification. We developed a FHIR-based dashboard to create a research patient record, enabling use cases, such as quality control and clinical trial pre-screening. The system addresses key challenges including FHIR implementation variability, differences in FHIR server capabilities and dynamic data de-pseudonymization. This is done by using a RESTful backend as an abstraction layer between the actual frontend and FHIR servers while supporting flexible, role-based access through OAuth 2.0 integration. Built as a multilayer web application that interfaces with an organization's infrastructure, the dashboard provides a wide range of customizable views for both aggregate and individual-level data visualization.
