| 90 min | North Start | Jeremy (US Digital Service) | - See slide deck and notes from Tuesday Q1 session
- Working with Virginia, USDS has created a prototype pipeline for data transformations and analytics
- Scope is reportable results (v2), immunizations (v2) and case reports (CDA) going to Virginia
- Data is consolidated from different PH programs in Virginia
- Authority to share and combine data is potential issue
- Driven by need to identify COVID break through cases
- Data is transformed/standardized to FHIR and stored to a FHIR server
- Data that can't be converted to FHIR are stored as "invalid"
- They are looking at using the NIST v2 validator for incoming v2 content
- Includes names, phone numbers, addresses (and Geocoding (via a third-party vendor))
- Patient linkage is being done after standardization
- Linkages can be used in a de-identified way via a standardized hash value
- Standardization at this point is for patients, but not other resources (but will with a goal to do so eventually)
- The conversion service has been containerized to be cloud agnostic
- That FHIR data is then extracted and tabularized for analytic tools to operate on
- There is an interactive schema generator to convert from FHIR to a tabular format
- The configuration file can be used by the tool so that FHIR calls can be made to extract the data for storing in a tabular format
- Supports Parquet and .csv formats but they are looking at other formats
- USDS also supports a re-conversion from the FHIR format back to a v2 message if necessary (currently for ORU messages but extensible)
- ReportStream
- Will be released as open-source Java code
- They are looking to start a Developer Community of Practice
- In November there is planned to be a FHIR Building Block Hackathon
- Investigating other jurisdictions to work with (including those with a lower level of technical expertise)
- Possible wish list:
- A way to extract data from the FHIR server for purposes other than tabularization (like reporting to other agencies)
- Variable solutions for security as some programs have very different security requirements
