Questionnaire Resource

Questionnaire/mii-qst-pro-promis-29

Capabilities:

  • Displayable
  • Collectable
  • Calculatable (all domain scores)
  • Extractable
  • Domain-aligned

Score Calculation

Each domain (except Pain Intensity) is calculated as a T-Score:

// FHIRPath
// Example: Depression Domain
%rawScore = %resource.item
  .where(linkId.matches('^promis-eddep(04|05|06|29)$'))
  .answer.value.ordinal()
  .sum()

// T-Score Lookup (simplified)
%tScore = iif(%rawScore = 4, 41.0,
          iif(%rawScore = 5, 49.0,
          iif(%rawScore = 6, 52.5, ...)))

Language Support

Primary Language: English (validated version) German Translation: Via Extension

{
  "text": "In the past 7 days... I could do chores",
  "extension": [{
    "url": "http://hl7.org/fhir/StructureDefinition/translation",
    "extension": [
      {"url": "lang", "valueCode": "de"},
      {"url": "content", "valueString": "In den letzten 7 Tagen... konnte ich Hausarbeiten erledigen"}
    ]
  }]
}

Implementation Notes

Variable-Based Architecture

The PROMIS-29 uses FHIR Variables for efficient multi-score calculation:

// FSH
* extension[variable][+].name = "promisDepRaw"
* extension[variable][=].expression = "[sum of depression items]"

// Raw Score Item
* item[dep-raw].calculatedExpression = "%promisDepRaw"

// T-Score Item
* item[dep-tscore].calculatedExpression = "iif(%promisDepRaw = 4, 41.0, ...)"

Known Limitations

  1. Item IDs: Currently MII-specific (promis-pfa11), not LOINC-conformant
  2. Validation Study Alignment: IDs are based on German validation studies
  3. Partial Responses: No handling of missing items
