Acquiring, encoding, and re-using clinical knowledge in PRODIGY

Abstract

The development, implementation and maintenance of computer-executable clinical guidelines encompass a series of complex processes. As they are often performed by more than one organisation, this introduces further complexity. Within the PRODIGY project we attempt to control as many aspects of the process as possible, in order to increase the likelihood of achieving success. To illustrate the complexity of the process and many of the inherent problems and solutions, this paper describes the evolution of the PRODIGY knowledge base, describing the steps from acquiring knowledge, through encoding, to the execution of guidelines, and 'closing the loop'by discussing an approach to knowledge re-use. We will also consider some of the wider implications of our work and propose directions for future research and development activities.
