OMOP Quality Measurement 20 April 2022

Follow up next steps from last 2 calls  - validate actions needed: Reminder from last call regarding COVID Criteria for cohort:

https://github.com/National-COVID-Cohort-Collaborative/Phenotype_Data_Acquisition/wiki/Latest-Phenotype; Describe requirements for the various components of the architecture - Seeking input from WG members:

Terminology:

• Infrastructure:
  • VSAC value sets and FHIR API
  • Programmatic methodology for extracting VSAC value sets and mapping terms to OMOP terminology (current manual upload)
  • Recommendations for handling concepts missing from OMOP (such as examples Qi experienced for HSLOC and CDC Race and Ethnicity Codes)
  • Subscription or periodic requery when VSAC updates the terminology
• Participants:
  • TBD

No additions to this content from last meeting:

Further detail would be use-case specific. Content requirements include characteristics to match the use case. Do we specify the use case and then build the data? If we assume the demonstration is the COVID and matched control cohorts - we would need ICD-10 on the terminology server (reference terminology in synthetic data) and assure the synthetic data meet the phenotype expression.

Content Requirements for COVID Use case: 

     Reference terminologies on servers: ICD10CM, SNOMED CT, LOINC, CVX

      Synthetic cohort data matching N3C phenotype:

                    COVID positive test results

                     Comorbid conditions

                      Possible:  Vaccine admin records

Expression:

• Infrastructure:
  • Atlas - SQL capability exists - need Atlas SQL instance for pilot testing
  • FHIR - CQL capability exists - need FHIR CQL instance for pilot testing
  • Expression conversion (what infrastructure is required here):
    • Atlas phenotype to FHIR cohort conversion
    • FHIR cohort expression with CQL to Atlas phenotype conversion
• Participants:
  • TBD

Data Query and Response:

• Infrastructure:
  • Atlas data store for synthetic patients
  • FHIR data store for synthetic patients
  • Query capability for Atlas patients and retrieve of OMOP cohort(s)
  • Query capability for FHIR patients and retrieve of FHIR synthetic cohort(s)
  • Structure to compare OMOP cohort with FHIR cohort, identify concordance and challenges
• Participants:
  • TBD

Discussion of OMOP-Atlas to FHIR-CQL conversion - what are next steps? Question of ability to present in the CMS Connectathon in July. CMS 2022 - 07 FHIR Connectathon 3, September, 2022 HL7 FHIR Connectathon.
