Uruz - Web-Based Clinical Guideline Markup, Editing and Specification Tool

Introduction: The Uruz Web-based guideline markup tool enables medical experts to: create new guideline documents. A source guideline is uploaded into the DeGeL, and can then be used by Uruz to create a new guideline document, marked-up by the semantic labels of one of the target ontologies available in DeGeL. Uruz can also be used to create a guideline document de-novo (i.e., without using any source) by directly writing into the knowledge roles of a selected target ontology. We are developing an Asbru-dedicated tool to add the formal-specification level.

A more complex module embedded in Uruz, the only one specific to the Asbru ontology (such modules can be defined for other ontologies), the plan-body wizard (PBW), is used for defining the guideline’s control structure. The PBW enables a user to decompose the actions embodied in the guideline into atomic actions and other sub-guidelines, and to define the control structure relating them (e.g., sequential, parallel, repeated application). The PBW, used by medical experts,
significantly facilitates the final formal specification by the knowledge engineer.

When a knowledge engineer needs to add a formal, executable expression to a knowledge role, she uses one of the ontology-specific Uruz modules (we are developing one specific to Asbru), which delves deeper into the syntax of the target ontology.

For example, in our hybrid Asbru, conditions can include temporal patterns in an expressive time-oriented query language used by all of the application modules. To be truly sharable, guidelines need to be represented in a standardized fashion. Thus, Uruz enables the user to embed in the guideline document terms originating from standard vocabularies, such as ICD-9-CM for diagnosis codes, CPT-4 for procedure codes, and LOINC-3 for observations and laboratory tests. In each case, the user selects a term when needed, through a uniform, hierarchical search interface to our
Web-based vocabulary server.
