Steps towards an industrial implementation of HSSP standards
1 like601 views
This document summarizes a project called HealthSOAF that aims to implement a framework of plug-and-play service components based on international health standards like HSSP. The project has a 3 year duration, €6.7M total cost with €4.3M in funding. It involves companies and universities working to design standard healthcare services, a testing framework, and a pilot implementation integrating clinical management of patients. The goals are to improve healthcare interoperability and efficiency through standardized service-oriented architecture approaches.
Steps towards an industrial implementation of HSSP standards
- 1. Steps towards an industrial implementation Open days 2012 Rome 7 June of HSSP standards F. Staccoli Castracane – Almaviva D. Guerri – Dedalus L. Maesano – Simple Engineering
- 2. Project Health Service Oriented Architecture Framework Project Lifetime: 3 years September 2011 August 2014 2011 2012 2013 2014 Budget: Total Cost: 6.7M € Total Funding: 4.3M € Co-funded by the Italian Ministero dell‘Istruzione, dell‘Università e della Ricerca within the “Programma Operativo Nazionale (PON) Ricerca e Competitività 2007- 2013” (National Research Programme)

- 4. Objective Implement a framework of plug-and-play SOA service components for second generation e-health based on HSSP international standards Addressing in a comprehensive and broad way the complex cooperation of a large number of heterogeneous healthcare entities (organizations, companies, users, systems, applications, devices) by supplying standard and interoperable general purpose services The HealthSOAF framework will allow integration of distributed back-end healthcare functions and front-end advanced interaction with and between patients, practitioners, operators and healthcare organizations
- 5. Expected results Services Design and implement standard, generic, plug-and-play, resilient and knowledgeable HSSP (RLUS, IXS, CTS2, HCSPD, DSS, PASS) service bricks Test framework Design, build and set-up an automated black-box test environment based on TTCN-3 and an interoperability test framework for HSSP services Pilot Build a Demonstrator – an implemented services architecture of a diagnostic- therapeutic process in a real healthcare environment Support the integrated clinical management process of cephalalgic and migraine patients Standards Assess the HL7 DSTU specifications and provide feedbacks Reverse model and check the OMG HSSP specifications and provide feedbacks Instantiate the generic services in compliance with the Italian healthcare guidelines and standards
- 6. Adopted approach (1) Project deliverables: Service bricks - for each HSSP service: Service consumer proxy library allowing applications, systems, intelligent devices to access service providers Ex.: Using RLUS primitives to retrieve health record elements Service provider skeleton library allowing systems endowed with enabling capabilities to provide the service Ex.: Encapsulate a MPI in order to provide IXS service functions Ex.: Encapsulate an IHE registry/repository in order to provide RLUS service functions Ex.: Encapsulate a IAA system in order to provide PASS Access Control service functions Service provider system Full implementation of the service provider Ex.: Full implementation of a healthcare practitioners and operators directory as a HCSPD provider Service brokers and multi-service providers to be built by composition of service bricks Ex.: A health record broker implementing RLUS provider and consumer parts Ex.: A healthcare system implementing patient demographics & health record management and providing RLUS & IXS service functions
- 7. Adopted approach (2) Contract-based, model-driven (CBMD) service orientation Service descriptions are service contracts - bundles of rights and duties for service providers and consumers Service contracts are Model Driven Architecture multi-layered models Service Computation Independent Model (CIM), Service Platform Independent Model (PIM), Service Interoperability Platform Specific Models (SOAP, REST… platforms – example: RLUS/SOAP vs. RLUS hData RESTful transport) Service models are collections of functional (and non functional) requirements for implementations The HSSP OMG specifications are models at the PIM / Interoperability PSM levels of the HSSP generic services Reverse formal modeling (OMG SoaML notation, simpleSOAD® methodology by Simple Engineering) of the OMG specifications at the PIM level – check the compliance with the corresponding HL7 Service Functional Models
- 8. Adopted Approach (3) Model-based automated testing In the CBMD service approach: interoperability = conformance of implementations with formal contracts / models – must be easily verified by testing Reverse formal service PIMs are the starting point of test case design and generation - Functional compliance, robustness, fault-tolerance and safety (absence of unintended side effects) tests to be modeled / generated from Service PIM in the project early stage Test and Test Control Notation (TTCN-3 - http://www.ttcn-3.org/) is a powerful language / environment for black-box testing automation – standardized by the European Telecommunications Standards Institute (ETSI - www.etsi.org) On the basis of Simple Engineering’s TTCN4SOA™, a TTCN-3 generic framework (library) that helps to build SOA automated testing environments, the HealthSOAF project will build a “standard” automated testing framework for HSSP generic services that can be instantiated for concrete healthcare services architectures The HSSP testing framework will be employed to build and run the HealthSOAF Pilot test campaigns and will be available as a project deliverable together with the HSSP service bricks Dependability and security of eHealth services architecture is a must – testability is a competitive advantage
