A Blockchain Architecture for the Italian EHR System

In the last years, significant changes of important socio-economic indicators, like population growth, life expectancy increase and patient mobility, have implied the need to provide new models for health provision. Thus, several efforts have been done to adequate and evolve the current ehealth systems for enabling them to gather patient health data produced by health facilities in an interoperable way and according to shared business processes. However, even if such systems are now starting at collecting health data, it is still not possible to verify that all the tasks of a specific process are correctly executed. This work presents a permissioned blockchain architecture designed to manage the Electronic Health Records of the users, able to track the operations performed by the actors involved in a health process. The architecture proposed is compliant with both the Italian Regulation on Electronic Health Record and the recently introduced GDPR. A proof-of-concept of the architecture has been developed and validated against a relevant use case.
