Success and failure factors in the regional health information system design process--results from a constructive evaluation study.
OBJECTIVE
To identify success and failure factors in the design process of a regional health information system.


METHODS
A constructive evaluation study including interviews, observations, usability study and document analysis.


RESULTS
Modelling was found to be a key element for the successful implementation of a health information system. The developed service chain model helped to define use cases and to implement seamless service chains. User participation in the design process was a success factor resulting in good user acceptance and signs of positive impacts on work practices. Evaluation study also helped system developers to guide the system's further development. An important failure factor identified was the lack of semantic interoperability of the system components.


CONCLUSIONS
The results emphasize the socio-technical nature of health information systems. The starting point for development should be thorough insight into the health care work practices where the information systems are to be used. Successful system design should start from modelling of work processes, data and information flows and definition of concepts and their relations. Health informatics as a scientific discipline provides theories and models for the design and development process.
