German Hospitals Scale Up Sepsis Data Sharing
A consortium of German university hospitals has developed an app that integrates data from multiple hospitals to support real-time treatment decisions for bloodstream infections. The project serves as a large-scale model for how health systems can use integrated data to standardize and improve care for complex conditions.
The German project is part of the SMITH consortium, one of four government-funded groups in the Medical Informatics Initiative (MII) working to create a nationwide research data infrastructure. From 2018-2022, SMITH established Data Integration Centers at seven university hospitals, including Aachen, Jena, and Leipzig, to process clinical data for research in a standardized, interoperable format. At the core of these data sharing initiatives is the HL7 FHIR (Fast Healthcare Interoperability Resources) standard, which has been endorsed by the ONC as the preferred standard for EHR interoperability. FHIR enables data exchange through standardized resources and APIs, allowing different EHR systems to communicate. Projects like "Sepsis on FHIR" are using this framework to create dynamic, federated data systems across multiple hospitals and EHR vendors. For ICU nurses transitioning to informatics, the American Nurses Credentialing Center (ANCC) offers the Informatics Nursing Certification (RN-BC). Eligibility typically requires a BSN, two years of RN experience, 30 hours of informatics continuing education, and a minimum of 2,000 practice hours in informatics nursing within the last three years. Many frontline nurses report that EHRs, often designed with a physician-centric workflow, increase documentation burden and contribute to burnout. Common complaints include slow system response times, excessive clicking, redundant data entry, and insufficient training during EHR implementations. More than half of nurses in one survey reported their EHR training was insufficient. In the U.S., the 21st Century Cures Act and its subsequent ONC Final Rule mandate increased interoperability and prohibit information blocking. These regulations require healthcare providers to adopt standardized APIs, giving patients and other providers electronic access to their health information, which drives the need for informatics expertise. Epic, which holds the records for over half of patients in the U.S., has an embedded Epic Sepsis Model (ESM) for early detection. However, independent research found the model's accuracy was not significantly better than a coin flip when restricted to data from before a clinician ordered a blood culture, suggesting it may be cueing on existing clinical suspicion rather than providing novel predictive insight. The model's performance has also been shown to be worse in hospitals with higher rates of sepsis and sicker patient populations.
