Clinical Decision Support Rules in an Archetype-Based Health Record System : Combining Archetype Query Language (AQL) and Semantic Web Rule Language (SWRL)

Sammanfattning: By using archetypes, it is possible to define how data are stored in the EHR,which facilitates querying for data. The objective of this thesis is to investigate the possibility of connecting a decisionsupport system to archetype-based medical records by using the ArchetypeQuery Language (AQL) and the Semantic Web Rule Language (SWRL). The result shows that, since SWRL is a logic language rather than a programminglanguage, built-ins are necessary to allow SWRL rules to function as programmingrules. Built-ins are SWRL modules that can be written in e.g. Java,which allows complex functions to be created. The conclusion is that built-ins can be used to connect archetypes and SWRLrules by querying the archetype path with AQL. There are however several ruledesign factors to consider when using SWRL e.g. data location problems.
