Topic: MeasureReport for continuous-variable evaluation

Miriam (Jun 05 2020 at 15:51):

Hello, I have some follow-up questions after reading this thread about MeasureReports: https://chat.fhir.org/#narrow/stream/226195-Covid-19-Response/topic/MeasureReport

I couldn't find the tracker you mentioned @Bryn Rhodes, let me know if these questions are already addressed somewhere in Jira.

1. Should the MeasureReport for continuous-variable evaluations include populations for initial-population, measure-population, and measure-population-exclusion?
2. If yes, how should the population size be calculated for initial-population and measure-population? I assume it would be "Episode-of-care-based" (the number of items (such as encounters) in each population) rather than "Patient-based" (the number of patients in each population), but this is not clear from the cv section of the IG.

Here's my current understanding of how it should look:

{
  "resourceType": "MeasureReport",
  "status": "complete",
  "type": "summary",
  "measure": "http://my-measure.com|1.0.0",
  "period": {
    "start": "2020-01-01",
    "end": "2020-04-01"
  },
  "group": [
    {
      "population": [
        {
          "code": {
            "coding": [
              {
                "system": "http://terminology.hl7.org/CodeSystem/measure-population",
                "code": "initial-population"
              }
            ]
          },
          "count": 200
        },
        {
          "code": {
            "coding": [
              {
                "system": "http://terminology.hl7.org/CodeSystem/measure-population",
                "code": "measure-population"
              }
            ]
          },
          "count": 200
        },
        {
          "code": {
            "coding": [
              {
                "system": "http://terminology.hl7.org/CodeSystem/measure-population",
                "code": "measure-population-exclusion"
              }
            ]
          },
          "count": 1
        }
      ],
      "measureScore": {
        "value": 0.2
      }
    }
  ]
}

Hi @Miriam, yes, a continuous variable Measure that had populations for initial, measure, and measure-exclusion, would be expected to have corresponding populations in the MeasureReport for that measure. And yes, in a continuous variable measure, the population-basis determines what kinds of cases are in the population, typically Encounters for a hospital CV measure
