Information Requisition is the Core of Guideline-Based Medical Care: Which Information is Needed for Whom?

Thesis by Theresia Gschwandtner

Supervision by Silvia Miksch and Katharina Kaiser


One indispensable precondition for designing a functional software product is to gather knowledge about (1) who is going to use the software, (2) which tasks does he/she want to perform with its help, and consequently, (3) which information is necessary to best support these tasks. Since the modeling and execution of a computerized clinical practice guideline is composed of numerous tasks and because a range of different stakeholders are involved - knowledge engineers, medical experts, nurses, and patients -, the design of a tool to support the whole life cycle of a computerized clinical guideline, i.e., from modeling the medical knowledge into a computerinterpretable representation to its actual execution in clinical care, is still a challenging issue. To this end, a comprehensive investigation of the user groups and the issues they encounter is a prerequisite to decide about the information and features that should be provided by the software. In the context of this thesis we have conducted a comprehensive literature study about the different tasks involved in modeling a clinical practice guideline into a formal representation as well as about the information needs of caregivers, i.e., physicians and nurses, and last but not least the information needs of patients. We have assessed and categorized the above mentioned information required for each task and user group in order to create a reliable starting point for the development of a functional software tool for the modeling process and execution of a computerized clinical practice guideline.
