Open architecture for health care systems: the European RICHE experience.
Groupe RICHE is bringing to the market of health IT the Open Systems approach allowing a new generation of health information systems to arise with benefit for patients, health care professionals, hospital managers, agencies and citizens. Groupe RICHE is a forum for exchanging information, expertise around open systems in health care. It is open to any organisation interested by open systems in health care and wanting to participate and influence the work done by its user, marketing and technical committees. The Technical Committee is in charge of the maintenance of the architecture and impact the results of industrial experiences on new releases. Any Groupe RICHE member is entitled to participate to this process. This unique approach in Europe allows health care professionals to benefit from applications supporting their business processes, including providing a cooperative working environment, a shared electronic record, in an integrated system where the information is entered only once, customised according to the user needs and available to the administrative applications. This allows Hospital managers to satisfy their health care professionals, to smoothly migrate from their existing environment (protecting their investment), to choose products in a competitive environment, being able to mix and match system components and services from different suppliers, being free to change suppliers without having to replace their existing system (minimising risk), in line with national and regional strategies. For suppliers, this means being able to commercialise products well fitted to their field of competence in a large market, reducing investments and increasing returns. The RICHE approach also allows agencies to define a strategy, allowing to create a supporting infrastructure, organising the market leaving enough freedom to health care organisations and suppliers. Such an approach is based on the definition of an open standard architecture. The RICHE esprit project defined in 1993 the three layered architecture, with four main components and their services of which the main principles have recently been adopted by the CEN TC251 as a european pre-standard. From this architecture specifications various implementations have been completed including the IMS DHE, the GESI DHE and the REFERENCE Kernel. However putting into practice this approach on a large scale is not so easy. Interesting lessons have been learned in the last years in different countries.
