The purpose of this thesis was to examine children’s right to self-determination within healthcare and to which extent guardians should receive information. The Swedish Children and Parents Code Chapter 6 Section 11, the Public Access and Security Act Chapter 12 Section 3 and the Patient Act Chapter 3 Section 3 constitutes the core of the thesis. The primary question is how they relate to each other. The thesis shows that guardians according to The Swedish Children and Parents Code Chapter 6 Section 11 has a right and an obligation to decide on issues related to a child’s personal affairs. The Patient Act Chapter 3 Section 3 states that guardians should receive the same information as a child, when the child is a patient. It can be concluded that information in regards to a child’s guardians is considered confidential as long as the situation is not covered by the Swedish Children and Parents Code Chapter 6 Section 11 or if it can be assumed that the child will suffer significant harm, according to the Public Access and Security Act Chapter 12 Section 3. If the child however has right to self-determination in the question at hand, it therefore disposes the confidentiality and information cannot be given to the guardians without consent from the child. It can also be concluded that even though a child has the right to self-determination in regards to a health care action, there might be situations where the risks of future injuries are so significant that the child cannot have the autonomy required in which case parental involvement is necessary. In those cases, the guardians should be informed about the situation. In reality guardians receive written information about a child’s healthcare through a journal online called Journalen via nätet and through copies of the journal on paper. The two methods hold age limits, which cannot be found in the legislation. The thesis shows that confidential information runs the risk of being disclosed without necessary consent due to these methods. Another risk is that guardians are prevented from receiving the information that the law ascribes to them.
