Integrating legacy medical applications in a standardized Electronic Health Record platform

An architecture for integrating legacy applications into the Romanian Health Information System platform is proposed. Such an integration is needed because a lack of interoperability between legacy medical applications and the Health Information Platform continues to exist. To solve the integration problem and create a true Unique Integrated Health Information System able to support all healthcare activities in the Romanian Health System the proposed architecture introduces a HL7-standardized Electronic Health Record (EHR) that uses cloud computing technologies and a HL7 Adapter. The Adapter integrates the legacy medical applications that generate electronic prescriptions in-house format as they are currently reported to the National Health Insurance House into the Electronic Health Record platform by converting their messages into HL7 Messages.
