• Passcode: ^W9mWTC?

Background:

Options for examples to address in the May FHIR Connectathon.

• Oncology concepts - outcomes for prostate cancer - potential process or outcome measures (Sebastian van Sandijk) - may be able to work with existing eCQMs - potentially stroke as well
• Mortality measures - ask Maria about public health mortality measure work - also interest in aligning COVID vaccination status and mortality
• Maryland perspective - suites including mortality, readmission, and several others - these may not be in eCQM/dQM format. In the ambulatory space, there are eCQMs which could be evaluated via Atlas.
• The mapping will be the most significant issue. Will need to work with the OMOP-FHIR mapping group.
• Daveera Gabriel - working on a COVID dataset to OMOP - if that is useful it can be used - looking at co-morbidities using VSAC value sets
  • https://ncats.nih.gov/n3c 
• Paul Nagy indicates his group has looked at Epic ETL to OMP for the vaccinations and conditions
• VSAC content should allow a one-time mapping exercise to the OMOP content to feed the eCQMs.
  • for any eCQM only using VSAC content (from standard code sets) - should be easier to implement - what else within eCQMs isn't using those standards?

Next All-Hands FHIR-OMOP meeting: Monday, February 14, 2022 

Discussion:

Narrowing down concepts for May HL7 FHIR Connectathon (will be virtual - May 3-4, 2022). Options:

• Measures in a number of US programs
  • Breast cancer screening
  • Colorectal screening - just updated to change age parameters
  • Maybe drill-down on what Atlas does with these phenotypes - maybe build out definitions to see what they look like (probably Python script to convert to FHIR-CQL definitions). The concepts do not necessarily exist in Atlas currently. https://github.com/OHDSI/PhenotypeLibrary
• Maryland - eCQMs required for reporting
  • Breast cancer
  • Colonoscopy
  • Diabetes
  • Pneumococcal vaccine
  • Depression screening
  • Others

Workflow process to participate in the May FHIR Connectathon

• Topic - run measure cohort on translated phenotype on OHDSI data - pick a clinical topic
• Need mappings/transforms from OHDSI to CQL representation - consider run-time translation? (White-rabbit utility in Github - useful for mapping local data to OMOP)
• Talk with OMOP mapping cohort to determine which has been/will be translated 
• Get FHIR CQL translation running
• Host server
• Participants to build the data

Tools - Atlas to create cohort, Achilles, other evaluate tools https://www.ohdsi.org/software-tools/ 

Reference using synthetic patient data (2008): https://www.ohdsi.org/web/wiki/lib/exe/fetch.php?media=resources:ohdsionfhir_gatech.pdf

We have ways to generate data based on measure definitions.

• Can we take and existing cohort definition from the OMOP phenotype and use it to build test data in FHIR. Use an existing OMOP Phenotype definition and obtain a measure numerator or denominator and build up FHRI data and run. Or, find a source of de-indentified real-world data and run it on those data.
• Another approach is to take a measure and automatically create an OMOP / OHDSI cohort. An existing measure run against OMOP. Automation for the data conversion will require participants who can consider how to automate.

Next steps:

• Floyd will contact Ben Smith to coordinate activities (OMOP-FHIR mapping next call is February 16).
• Ben Hamlin will reach out to Gowtham for interest in assistance as well.
• Need to encourage participation since this is basically a volunteer project team - request interest in Zulip chat and to the listserve.

Adjournment - The meeting was adjourned at 10:46 AM ET. The next scheduled meeting will be February 9, 2022.
