10.2.4 | TTA FHIR - Pull

This exchange pattern (Direct Pull) is informative. Not for implementation in Twiin 1.2

This Twiin Technical Agreement (TTA) describes and specifies technical responsibilities to which parties agree when connecting to exchange transactions to facilitate the Direct Pull.

The retrieval of a patient’s medical record might for instance be initiated to retrieve history when the patient is scheduled for a patient requested second opinion. This transaction will only be supported with explicit consent of the patient.
