Invalid reference in MR generated from reportType=subject-list

[rob-reynolds]

IS: Relative references in the List resources do not include the resource type. Example:

"item": {
    "reference": "nocoverageconcern-sedconcern-sigcomp"
}

SHOULD BE: Relative references in the List resources should include the resource type. Example:

"item": {
    "reference": "Patient/nocoverageconcern-sedconcern-sigcomp"
}

REPRO:

1. Run $evaluate-measure with the reportType parameter set to subject-list. Example: http://localhost:8000/Measure/ColorectalCancerScreeningsFHIR/$evaluate-measure?reportType=subject-list&periodStart=2024-01-01&periodEnd=2024-12-31
2. Note the List resources in the MR contain invalid relative references. Example:

{
    "resourceType": "List",
    "id": "56222060-b037-4388-a20c-3d2d744b443a",
    "entry": [
        {
            "item": {
                "reference": "nocoverageconcern-sedconcern-sigcomp"
            }
        }
    ]
}

See comments for files that will generate a repro although a simpler repro is any subject-list MR.

Note: the local ("internal fragment") references in the MR are correct. Example: "reference": "#6d3637d3-f7a1-4c28-b717-554d90fa5398"

Testing should ensure the local references are still correct after the relative references are fixed.

All the FHIR resources needed to repro this issue (requires access to a private repo):

• https://github.com/alphora/demo-content-r4/blob/cpg-format/bundles/cc-cds-patient-data-bundle.json
• https://github.com/alphora/demo-content-r4/blob/cpg-format/bundles/cc-cds-resources-bundle.json
• https://github.com/alphora/demo-content-r4/blob/cpg-format/bundles/configuration-bundle.json

Once posted you can call the operation example above (http://localhost:8000/Measure/ColorectalCancerScreeningsFHIR/$evaluate-measure?reportType=subject-list&periodStart=2024-01-01&periodEnd=2024-12-31).

@rob-reynolds per subject-list specification in r4 MeasureReport.

The current subject-list generates the incorrect subjectResults reference members. These should be a list of referenced MeasureReports per subject in each population per: https://www.hl7.org/fhir/R4/measurereport-definitions.html#MeasureReport.group.population.subjectResults

currently we are only doing subjectResults with a list of patients references, which is closer to r5's subjects https://hl7.org/fhir/R5/measurereport-definitions.html#MeasureReport.group.population.subjects , which is not supposed to be a List resource, but actually a Group.

So possibly two fixes needed here:

1. BugFix: Update current subjectResult List to be MeasureReport not Patient resources
2. Enhancement: Add r5 capability for subjects to show per population, referencing a Group resource with member resources = Patient with correct ResourceType identified
