GUIDELINE-BASED DECISION SUPPORT

A system for decision support comprises a path unit (10) for determining a determined path through a decision tree (2) that leads to a determined recommendation node (4) comprising a determined recommendation. The decision tree (2) comprises condition nodes (3) and recommendation nodes (4), wherein a condition node (3) comprises a condition associated with a particular branch of the decision tree (2). A recommendation node (4) comprises a recommendation associated with the one or more conditions of the one or more condition nodes (3) on a path towards the recommendation node (4). The path unit (10) is arranged for taking into account the conditions of the condition nodes (3) along the path by applying the conditions to a set of parameters (1). The system comprises an explanation unit (11) for generating an explanation of a reason for the determined recommendation based on at least one of the condition nodes (3) on the path that leads to the recommendation node (4).
