The disease

The disease profile is used to represent the disease under study for which the patient was enrolled. This means that the patient must have a status (affected/unaffected) for the given disease.

Summary

Disease Designation

Patients identified as affected or unaffected for a given disease will have a condition object linked to their patient record containing one or more Coding entries assigned to Condition.code. Condition.code.text will contain the textual description of the disease. The first Coding object present must be one of the disease codes

Affected Status

Affection status is mapped to the standard parameter, Condition.verificationStatus using the corresponding hl7 codes.

recordedDate vs onset

Depending on the data available, data may be tagged with a date in either Condition.recordedDate or Condition.onset using the extension relativeDateTime where recordedDate is presumably the earliest date at which this disease was noted in the patient’s record. Onset would be specified only when the actual onset was established and recorded as such. The relative date targets the patient’s birth date.
