The healthcare domain is wide and characterized by system and data herogeneity. To achieve high quality and efficiency standards, interoperability between different information systems is strongly required.

The aim of this paper is to propose an agent oriented architecture to address this kind of issues, which is compliant with the European Union (EU) guidelines and with requirements issued by the italian Ministry of Health. To validate and to show the capabilities of our system, we developed on such architecture a typical emergency-response scenario, where a first aid medical staff urgently needs to retrieve, through mobile devices, the Patient Summary (PS) of a citizen, which is part of his Electronic Health Record (EHR).
