Template Integration

The reporting application utilizes a observationValue(code) formula field to auto populate these fields. The following is a minimized Observation resource with a US_CAROTID_RT_CCA_PROXIMAL_PSV measurement from a carotid artery ultrasound

{
  "resourceType": "Observation",
  "code": {
    "coding": [
      {
        "code": "US_CAROTID_LT_CCA_PROXIMAL_PSV" // This is the key we use to match for the formula
      }
    ]
  },
  "valueQuantity": {
    "value": 11.467,  // Actual measurement, will be displayed with no formatting as a fall back if the narrative is not populated
    "unit": "cm/s",
    "system": "UCUM"
  },
  "text": {
    "status": "generated",
    "div": "<div xmlns\"http://www.w3.org/1999/xhtml\">The peak systolic velocity of the left proximal common carotid artery is 11.5 cm/s.</div>" // Optional: displayed to the radiologist when populated
  }
}

The Reporting template will then refer to a observationValue("US_CAROTID_RT_CCA_PROXIMAL_PSV")

info

If a duplicate code exists for the study, the last updated Observation resource will be used.

Inside of the report itself these observations become navigatable fields:
