Electronic patient journals

We live in one of the most developed country, right?
"There are examples of cases where a death could have been avoided if only it had been possible to have common access to the patient's data." DR
I have asked all the doctors why we do not already have this data. It's strange. For example I have alergy to some medecine and I could easily die if a doctor doesn't know that. Thanks Satan we are living in such a small land. What the Danish government would do it Denmark was as big as India!
