1. Improving Clinical Guideline Implementation through Prototypical Design Patterns Monika Moser, Silvia Miksch {moser, silvia}@ifs.tuwien.ac.at Institute of Software Technology & Interactive Systems Vienna University of Technology

2. 2 MOSER & MIKSCH Aim Formal Representation Raw Clinical Guidelines & Protocols Knowledge Engineers Domain Experts Finding Prototypical Design Patterns Implementing Prototypical Design Patterns

3. 3 MOSER & MIKSCH Approach Guideline Basis Guideline Pool National Guideline Clearinghouse www.guideline.gov Guideline Pool National Guideline Clearinghouse www.guideline.gov 1. Definition of Relevant Criteria for Guidelines: medical & technical criteria 2. Selection Process 4. Development of Macros with Asbru and DELT/A Macro FilePreview: plain source Macro: xor_structure_macro Preview: tree view 3. Analysis and Definition of Pattern Structure Pattern Temporal Pattern Element Pattern

4. 4 MOSER & MIKSCH Results Software Pattern Approach: failed! Text Linguistics Approach: successful! Clinical Guidelines were not as qualified for the work done as it had been expected before Reasons Very high level of abstraction Evidence-based character Consequences Few temporal dimensions Few intentions No algorithms Clinical Protocols would be more appropriate !
