Summary

Objectives: Interoperability of applications in health care is faced with various needs by patients, health professionals, organizations and policy makers. A combination of existing and new applications is a necessity. Hospitals are in a position to drive many integration solutions, but need approaches which combine local, regional and national requirements and initiatives with open standards to support flexible processes and applications on a local hospital level.

Methods: We discuss systems architecture of hospitals in relation to various processes and applications, and highlight current challenges and prospects using a service-oriented architecture approach. We also illustrate these aspects with examples from Finnish hospitals.

Results: A set of main services and elements of service-oriented architectures for health care facilities are identified, with medium-term focus which acknowledges existing systems as a core part of service-oriented solutions. The services and elements are grouped according to functional and interoperability cohesion.

Conclusions: Atransition towards service-oriented architecture in health care must acknowledge existing health information systems and promote the specification of central processes and software services locally and across organizations. Software industry best practices such as SOA must be combined with health care knowledge to respond to central challenges such as continuous change in health care. A service-oriented approach cannot entirely rely on common standards and frameworks but it must be locally adapted and complemented.
