Notification of system changes

A system supplier must notify Kela and an information security inspection body of any significant changes to an information system connected to Kanta services.

Kela must be notified of any changes made to the functionalities or interface of the Prescription Service, the Patient Data Repository, the Expression of Will Service, the Social Welfare Customer Data Repository, the Image Data Repository or the Well-being Applications’ Interface to Patient Data Service.

THL Regulation 4/2024 Appendix 2(opens new window) (thl.fi, in Finnish) “Notification of changes to social welfare and health care information systems belonging to class A” (in Finnish) describes in more detail what are the type of significant changes for which a notification must be submitted.

Submit the change notification through Testain

The change notification is submitted through the registration form of the Kanta joint testing Testain service, and on the basis of this, the joint testing expert assesses whether joint testing is required due to the change. 

Select the Kanta service on the registration form and select Change notification as the testing content. It is good to attach a more detailed description of the content of the change and, if necessary, an updated system form. Instructions and additional information can be found in the Testain service and on the pages linked below:

Assess the impact of the change on the interoperability of systems

When planning changes, a system supplier must take into account any effects on the interoperability between information systems related to the Kanta services. In addition, you must assess whether the changes have such impacts on interoperability that joint testing coordinated by Kela is needed, or whether independent testing by the system supplier in the Kanta customer test environment is sufficient. Changes to Kanta services based on legislation and national change management will continue to be tested under joint testing coordinated by Kela.

The change notification will be processed as soon as possible. In the case of urgent repairs that do not require joint testing, the repair can be put into production without the joint testing. If joint testing coordinated by Kela is needed to test the Kanta interoperability of the changes, the change notification must be submitted at least one month before the intended testing, so that Kela can then plan the required joint testing.
