FUME is a comprehensive Legacy-to-FHIR transformation solution consisting of two primary components: FUME Engine and FUME Designer. 

  • FUME Designer offers an interactive interface to create and manage conversion mappings.
  • FUME Engine provides powerful two-way Legacy-to-FHIR® conversion capabilities via API. FUME engine functions as a bridge, empowering disparate systems to interact through FHIR, regardless of their internal data formats. 

Together, FUME Engine and FUME Designer set the benchmark for transforming legacy data, including HL7v2, to and from FHIR®.

No, FUME is not an ETL (Extract, Transform, Load) tool. Instead, it operates as a specialized transformer/mapper, facilitating conversions between diverse data structures and FHIR.

FUME’s role diverges from traditional ETL systems in that it does not extract or load data. Rather, it synergizes with existing tools, including ETL systems, on these processes.

While FUME does not fall into the ETL tool category, it significantly enhances the ‘T,’ or Transformation, aspect of ETL. It efficiently translates data into FHIR format and vice versa. 

This is made possible by designing (via FUME Designer) and implementing (through FUME Engine) conversion maps that provide detailed instructions on how to transform one data format into another. FUME exposes the customized Conversion Maps as APIs, creating a bridge for other tools to use. 

By simplifying the mapping and conversion of data to and from the FHIR format, FUME complements rather than replaces ETL tools and processes.

FUME provides a wide range of benefits that greatly enhance data transformation processes and interoperability. Here are some of the key advantages:

  1. Interoperability: FUME serves as a dynamic connector, seamlessly bridging various systems via FHIR. By exposing customized conversion maps as APIs, FUME acts as a flexible bridge between systems, enabling different platforms to communicate seamlessly via FHIR without the need for modifications to their internal data structures. 
  2. Empowering data analysts: FUME offers a user-friendly mapper which simplifies the management and configuration of conversion mappings. Its intuitive graphic interface empowers users, even those without coding expertise, to manage data transformations independently without developers.
  3. Streamlined Development: FUME’s uniform API removes the need for custom FHIR adaptations. This not only speeds up the process but also reduces the likelihood of errors associated with customized solutions.
  4. Efficient Data Transformation: FUME specializes in converting data from any format into FHIR format and vice versa, ensuring the compatibility of any system with FHIR.

One of the major advantages of FUME is that it does not require advanced programming or integration expertise, making it suitable for a wide variety of users.

FUME is a user-friendly tool designed with system analysts, data specialists, and implementation professionals in mind. These users can seamlessly create and manage data conversion maps for Legacy-to-FHIR transformations, all without the need for advanced programming or integration skills.

In terms of organizational use, FUME is particularly beneficial for healthcare institutions, health tech startups, medical research facilities, health insurance companies, and any organization seeking to leverage FHIR for improved data interoperability.

Yes, the core engine of FUME, which handles conversions and runs conversion maps, is indeed open-source and freely accessible. In addition, FUME provides the Playground—a public sandbox hosted on Outburn’s public server—where users can experiment and gain hands-on experience with FUME Designer in an interactive environment.

A combination of the open-source FUME Community and FUME Playground serves as an excellent starting point for effortless FHIR conversion, especially for smaller-scale projects or initial exploration.

FUME also offers an enterprise-grade edition called FUME Enterprise that offers enhanced capabilities, dedicated support, and advanced functionality for organizations seeking a comprehensive solution for their advanced data transformation requirements.

FLASH is an enhanced syntax developed by Outburn.

FLASH language is built upon the foundational FSH (FHIR Shorthand), combined with JSONATA’s advanced functionalities for dynamic interaction with the structures of source systems. 

The key benefit of FLASH is its efficiency and simplicity – it allows you to generate a JSON representation of an entire FHIR resource with just a few commands.

FLASH empowers users, even those without extensive programming knowledge, such as system analysts, to create their own transformations.

While FUME is capable of executing transformations without the need for a dedicated FHIR Server, having one expands the possibilities with our product.

FUME’s engine makes use of your existing FHIR Server to store your StructureMaps, making your customized mappings accessible via APIs that can be called from any system. By calling FUME APIs, you can convert your structured input data into FHIR or transform it into a native data structure using your custom conversion functions. 

However, if you do not have your own FHIR server to store your mappings, FUME has got you covered. You can utilize FUME’s built-in Conformance Server to store your mappings.

Absolutely. FUME is designed with integrated support for FHIR profiles, ensuring compatibility with both current and future FHIR standards. Importantly, it also supports Implementation Guide (IG) Core packages, with full support for IL CORE packages.

Absolutely. FUME is designed to handle conversions of value sets and coding systems directly within the mapping. Moreover, we are future-ready – upcoming versions of our product will facilitate the import of CSV files and other formats to streamline non-hierarchical coding system conversions.
