For the citizens the EHR could be a kind of single point of access to the public health system. Citizens needs both to be familiar to that service and to use it. Currently, a very small portion of citizens uses the EHR. This raises several questions, the first one concerns the communication from the government systems with respect to the citizens. From the point of view of computer scientists we analyze two critical issues to the diffusion and adoption of EHR. The first issue is the person-computer interface. For the citizens this is the only interface to the system and represents the system tout court. Currently, this interface shows several limitations; we discuss some of them, that we consider as the more perceptible. The second issue is the system architecture and in our opinion this is the more important one. Currently, the system architecture follows the SOA paradigm. We propose a new architecture based on the REST paradigm. We believe that the adoption of this approach represents a huge improvement with respect to the actual system. Moreover, our approach allows for characteristics that now are hardly to obtain, if not impossible.
