Patient Identifier Cross-reference for Mobile (PIXm)

This section specifies Swiss national extensions to Patient Identifier Cross-referencing for mobile (PIXm) profile. PIXm is published as an IHE ITI Trial Implementation profile.

Scope

In the Swiss Health Dossier, the PIXm profile ensures that different systems can update the patient contact information.

Use Cases

Patient data like address, contact information (phone number, e-mail) are allowed to be updated by a Health App.

Actors and Transactions, Content Specifications

This national extension adds restrictions to only allow updating of a contact information of a patient. Otherwise there are no extensions or restrictions to the profile actors and the transaction.
