First health records of patients are exchanged in the EU thanks to the cross-border electronic health services. As of now doctors in Luxembourg will be able to receive digital Patient Summaries of travellers coming from Czechia. These Patient Summaries provide background information on important health-related aspects such as allergies, current medication, previous illness, surgeries, etc., making it digitally accessible in case of a medical emergency visit in another country.
