Those notes don't need to be persisted in any central database though. And while they are stored temporarily they do not ever need to be decryptable by anyone except that one therapist (by way of physical token or biometrics or, you know, paper locked in a drawer) I really hope this practice is not mandated by the government... if it is then my view of Finland is going to change a lot
