Depending on their access rights, each professional category has access to some shared data. Access rules vary depending on which kind of professional consults your data. For example, a pharmacist can’t see your lab results but a doctor may see medication that has been prescribed to you.
As it stands at the moment, at national level, only doctors and pharmacists have access to your data. The default access rules for other health professionals (what information can be consulted by nurses, physiotherapists, etc.) are being gradually established.
Remember, that in order to exist, this “therapeutic relationship” must be proved: this being the case when you give your electronic identity card to the admissions department of a hospital, a doctor or a pharmacist.
