When the procedure for acting on behalf of a minor is in use, the health care professional assesses and records the minor's decision-making capacity during an appointment. If the minor is not able to make their own decisions, their information will be visible to the guardian on MyKanta. If the minor is deemed to be capable of making their own decisions, they can decide for themselves whether their guardian can see their information.

A health care professional assesses a minor's decision-making capacity in connection with each service event (in-person appointment, course of treatment or remote contact) and whenever prescribing or renewing a prescription.

The assessment is made on a case-by-case basis, taking into consideration the age and level of development of the child and the purpose of using health care services on that occasion. With very young children, the assessment of decision-making capacity is based on the level of development generally accepted for the child’s age. The information must be entered in a structured way in connection with both the appointment and the prescription. 

​​​​​A minor who has been assessed to be capable of making decisions may refuse to share the following data with his or her parents or guardians:

  • information related to the appointment
  • information related to the treatment period
  • information related to prescriptions.

Data concerning a child over 10 years of age that has no accompanying information about the minor’s decision-making capacity and their wish to share data will not be shown to parents or guardians.
