period of time, increasing the levels of stress which usually harms the outcome of healthcare processes. The short time
practitioners have with their patients does not facilitate informed decision making and checking all possibilities. A
possible solution is the use of guideline-based applications, because they have the potential of being an effective means
of both changing the process of healthcare and improving its outcomes. However, current Clinical Guidelines are
available in text format as long documents, which render them difficult to consult and to integrate in clinical Decision
Support Systems. With this paper we present a new model for guideline interpretation, in order to facilitate de
development of guideline-based Decision Support Systems and to increase the availability of Clinical Guidelines at the
moment of the clinical process. This model will also provide mechanisms to comply with cases where incomplete and
uncertain information is present. The development and implementation of this model will be presented in the following pages
