The primary focus is exchange of complex eligibility criteria (inclusion and exclusion criteria) for research cohorts, clinical trials, and clinical care recommendations.
Using the characteristic backbone element of the Group resource to express criteria is well established but the approach has limitations for complex criteria.
The Evidence-Based Medicine on FHIR project group (co-sponsored by CDS, CQI and BRR WGs) developed EvidenceVariable Resource to express complex characteristics defining evidence variables. In a separate BRR track focusing on a review of inclusion / exclusion criteria, discussion on the need to express complex characteristics converged on EvidenceVariable.
With a desire to describe eligibility criteria using Group Resource but a demand for handling many complex characteristics and combinations of characteristics, we will explore adapting the EvidenceVariable Resource to structure such content, easily referenced from a Group Resource.

Track Kick Off Call
Pre-connectathon Track Orientation
Thursday April 21st 12 Eastern
If you missed the call you can listen to the recording here: https://hl7-org.zoom.us/rec/share/DmcDxJ06V6jbHr4d2ZO1o8t9ClzHvqV2oCeohr9YEPCuJXsUSe7XEUVkEHGEIk5J.ycDF5gsjM37yU7a-?startTime=1650557099000
Expressing Eligibility Criteria
Select complex eligibility criteria (e.g. from research studies described at ClinicalTrials.gov) and express using EvidenceVariable Resource.
Track participants are able to express eligibility criteria with satisfactory degree of granularity.
Track participants are able to interpret eligibility criteria expressed by other participants.
Security and Privacy Considerations: None
