Summary
Objectives:
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.
