Interoperability in today’s healthcare world is big challenge. Although a number of standards have been developed in this domain yet the realization is still a key challenge. Health Level 7 (HL7) is an information exchange standard which formulates specifications for interoperable communication. HL7 V3 uses Messaging Infrastructure (MI)for the communication but it cannot provide flexible communication environment. It is required to have end-to-end sessions and business scenarios from real healthcare environment. Service Oriented Architecture (SOA) provides a platform for system development and integration in order to achieve the main goal of interoperability along with flexibility. In HL7 V3, the communication between systems takes place using process artifacts (application roles, interactions, trigger events and information models). SOA based HL7 V3infrastructure consists of application roles as services that are responsible for the interaction between communicating entities. Our system provides services that have business perspectives in terms of capturing healthcare business workflows. The work in this paper is based on the HL7 V3specifications and also uses certain guidelines of Healthcare Service Specification Project (HSSP).
