Welcome to the E17 on FHIR Wiki.
With the “E17 Hospital Network on FHIR” project, we aim to facilitate and scale the ambitions related to data reuse for hospital‑network purposes. Our goal is to create a sustainable solution for all participating hospitals that enables both primary reuse (data exchange across different care domains) and secondary reuse for purposes beyond the network. To achieve this, locally available data will be converted into standardized terminologies (such as SNOMED‑CT, LOINC, ATC, depending on the datatype) and stored locally in a FAIR (Findable, Accessible, Interoperable, Reusable) FHIR format. These local FHIR repositories will be queryable via a local FHIR station, enabling federated data exchange within the E17 hospital network—and later, also with other partners.
At the network level, we aim to build an E17 Data Space, where federated analytics will allow pseudonymized data from the different hospitals to be stored and processed per use case. The resulting analyses will be made available to all network members under the appropriate governance structures. This setup moves us toward a scalable framework for improved data aggregation and clearer data governance, allowing hospitals to maximize the value of their data both within and beyond the network.
These objectives will be developed through two use cases. After establishing the local FHIR repositories, “Mother & Child” variables (SPE registrations) will be mapped to SNOMED‑CT and stored in FHIR format across all seven hospitals. Subsequently, federated analytics will be tested for this use case using FHIR queries. Results will be displayed in a clinical dashboard within the E17 Data Space, allowing clinicians to compare metrics—such as primary or secondary C‑section rates—between hospitals.
In a second phase, and in the context of the HOST project, we will convert available laboratory, pharmacy, and ADT data into a unified semantic standard (LOINC, ATC, SNOMED‑CT) and format (FHIR). This will enable high‑quality and efficient monitoring of antibiotic use and resistance across the hospitals.
Finally, once the technical foundations have been validated, the FHIR repositories will be expanded with additional FHIR datapoints. This will increase the number of supported use cases and ensure that the established infrastructure is fully leveraged.
