The Data Hub
A Source for Real-World Hematology Data
The ASH Research Collaborative® Data Hub receives electronic health data for Sickle Cell Disease (SCD) and Multiple Myeloma Programs, which also receive locally curated data.
The Data Hub aggregates and curates data from various electronic health record sources. To reduce the ongoing data submission burden for sites, there are three submission pathways that leverage the most popular interoperability standards in use today. Sites participating in the Multiple Myeloma Program may also submit data through the electronic case report form (eCRF) or through a flat file upload.
These models help ensure that each disease-specific program has a harmonized data model, meaning that data with different formatting, naming, and organization frameworks can be brought together and transformed into a cohesive dataset.
Observational Medical Outcomes Partnership (OMOP)
The Data Hub currently accepts data that conforms with the OMOP Common Data Model (version 5.2 or higher). OMOP formatted data is shared with the Data Hub through an encrypted file transfer method, which sites may set up as a manual or automated process.
The Data Hub provides a fully documented command-line tool and submission credentials. Your site can use this tool to validate your files’ conformance to the OMOP specification and submit the files to the Data Hub. The tool’s source code is also publicly available, so your site can also review the tool’s functionality and replicate it instead, if preferred.
Fast Healthcare Interoperability Resources (FHIR)
The Data Hub accepts data conforming to R4 of HL7 FHIR. FHIR data is shared with the Data Hub via secure application programming interfaces (APIs). All client/server interactions specified by FHIR R4 are supported (e.g., push, pull, bulk, etc.).
FHIR Application Programming Interface (API)
The Data Hub offers direct integration with participating sites’ electronic health records systems using industry standard HL7 FHIR APIs. 1upHealth provides the API connection and data capture services for the Data Hub.
Captured data for each site are stored in an Amazon Web Services dedicated FHIR store where they are retrieved by the Data Hub for processing. The Data Hub and 1upHealth work with each site’s IT staff to configure the API connection for bulk data transfer with the goal of minimizing the work effort of the IT team. Configuration details are provided for a site’s specific electronic health records system.
Data Curation and Validation
Once the Data Hub receives a submission from a site, a pre-populated eCRF will be generated. This gives sites the opportunity to amend data where there are concerns about completeness and accuracy.
Participating sites submit data on cumulative patients at least quarterly.
