Digital health care ecosystem: SOA compliant HL7 based health care information interchange

Increasing demand for health care services pose a number of challenges to healthcare industry and one of them is sharing health care information among heterogeneous health care information systems. Digital health care ecosystem aims at providing continues treatment process requiring seamless information sharing across multiple healthcare providers/organizations. Different health care standards and technologies have been proposed to address this challenge. HL7 is one of the standards for information sharing involves object oriented modelling to the development and specification of information being interchanged. It also specifies transportation specification for message exchange named as web service profiles. We propose Service Oriented Architecture (SOA) compliant HL7 based system architecture for health care information interchange. The proposed architecture comprises of Web Service Adapter, HL7 V3 message parsing/generation, V2 to V3 translation and database mapping to HL7 modelling elements. We describe in detail the WSDL construct document for the Result Query Filler application role in Laboratory domain.
