“…The method was applied to selected articles and abstracts of PubMed but not to CPGs. In [8] a heuristic-based approach using information extraction methods independent of the final guideline representation language was defined. This method was implemented and applied to several guidelines containing a high amount of semi-structured text.…”

Abstract. Translating clinical practice guidelines into a computer-interpretable format is a challenging and laborious task. In this project we focus on supporting the early steps of the modeling process by automatically identifying conditional activities in guideline documents in order to model them automatically in further consequence. Therefore, we developed a rule-based, heuristic method that combines domain-independent information extraction rules and semantic pattern rules. The classification also uses a weighting coefficient to verify the relevance of the sentence in the context of other information aspects, such as effects, intentions, etc. Our evaluation results show that even with a small set of training data, we achieved a recall of 75 % and a precision of 88 %. This outcome shows that this method supports the modeling task and eases the translation of CPGs into a semi-formal model.

“…After combining them with medical domain knowledge this enables an easier formalization and maintenance of guideline models. A similar approach was pursued by Kaiser et al [10], who defined syntactic and semantic patterns that are used to develop extraction rules to identify and extract actions and processes out of guidelines. The patterns were based on the UMLS Semantic Network and its semantic relations.…”

“…The necessity to instantiate them into clinic and hospital protocols and workflows has given rise to computer-interpretable guidelines (CIGs), see [3], viz., formal representations (constructed typically with process representation languages) of the care process or plan. On the other hand, several natural language processing (NLP) techniques have been developed to fully or partially automate their processing, see [10], until now manual, and therefore both time and cost consuming.…”

Abstract. We describe a first experiment on automated activity and relation identification, and more in general, on the automated identification and extraction of computer-interpretable guideline fragments from clinical documents. We rely on clinical entity and relation (activities, actors, artifacts and their relations) recognition techniques and use MetaMap and the UMLS Metathesaurus to provide lexical information. In particular, we study the impact of clinical document syntax and semantics on the precision of activity and temporal relation recognition.

Abstract. Health care systems are facing new challenges such as the aging population, the increasing amount of chronicle diseases and the rapid development of medical technologies. The increasing of the related health care costs lead to the limits of affordability of health care systems. Building Health networks and standardization of clinical processes are the main trend facing these challenges. Actually, the main instrument for documentation and managing of clinical processes are Clinical Pathways (CPs). They allow to transfer evident knowledge in practice and they are the central point of clinical quality management. In contrast, Clinical Practice Guidelines (CPGs) aggregate the evident medical knowledge in a compact form to support physicians in their practice. In the paper analyze the model-driven development of CP for a health network. Therefore, we work out problems of integration. Finally, the paper shows aspect for a model-based integration of CPGs in CPs. These findings are proofed with the help of the documentation of the regional stroke-network called SOS-NET.

How can information extraction ease formalizing treatment processes in clinical practice guidelines?

Abstract: Our evaluation shows that a heuristic-based approach can achieve good results, especially for guidelines with a major portion of semi-structured text. It can be applied to guidelines irrespective to the final guideline representation format.
