The formalization of clinical guideline knowledge is a prerequisite for the development of guideline-based decision support tools that can be used in clinical practice. Several guideline representation languages have been developed to formalize clinical guidelines and execute them over individual patient data. However, no standard has emerged from these efforts, and the core guideline elements to be represented have not been agreed upon in practice. One result is that there is little support when it comes to re-engineer a guideline modelled in a specific language into another language with different features. In this paper we describe a practical exercise consisting in modelling a guideline fragment in a target representation language starting from the same fragment modelled in a source language, having the source and target languages very different features. Concretely, we used PROforma as the source language and GDL as the target one. We also describe a methodological approach to ...

This paper describes some lines of research of the Knowledge Engineering group at Universitat Jaume I, which investigates the construction of knowledge-based systems with an emphasis on practical applications. In particular, the paper presents a selection of research lines in the context of ComputerInterpretable Guidelines, a topic in which the group has specialised over the last years.

Clinical Practice Guidelines (CPGs) contain recommendations intended to optimize patient care, produced based on a systematic review of evidence. In turn, Computer-Interpretable Guidelines (CIGs) are formalized versions of CPGs for use as decision-support systems. We consider the enrichment of the CIG by means of an OWL ontology that describes the clinical domain of the CIG, which could be exploited e.g. for the interoperability with the Electronic Health Record (EHR). As a first step, in this paper we describe a method to support the development of such an ontology starting from a CIG. The method uses an alignment algorithm for the automated identification of ontological terms relevant to the clinical domain of the CIG, as well as a web platform to manually review the alignments and select the appropriate ones. Finally, we present the results of the application of the method to a small corpus of CIGs.

Clinical practice guidelines (CPG) represent standard sets of recommendations for the clinical handling of patient affections of a concrete pathology. They reflect the best scientific evidence available for such pathology. Its adoption by health-care professionals has a direct impact in the quality of the assistance, fostering the standardization of the interventions. In spite of the interest of their application and use, the adherence of professionals to CPG has been observed below the desirable level. Two are the main reasons: 1) the difficulty to adapt standard CPGs to the particularities of each health care center and 2) the little synchrony between CPGs and the particularities of work practices that often reflect the specifics of work places. Both factors influence negatively in the viewpoint of doctors and other health care professionals, making them reluctant to use CPGs in the clinical decision making. Regardless of the reason, this poor adherence lowers the quality of the h...

Background: Clinical Practice Guidelines (CPGs) include recommendations to optimize patient care and thus have the potential to improve the quality and outcomes of healthcare. To achieve this, CPG recommendations are usually formalized in terms of Computer-Interpretable Guideline (CIG) languages. However, a clear understanding of CIG models may prove complicated, due to the inherent complexity of CPGs and the specificities of CIG languages. Drawing a parallel with the Business Process Management (BPM) and the Software Engineering fields, understandability and modifiability of CIG models can be regarded as primary quality attributes, in order to facilitate their validation, as well as their adaptation to accommodate evolving clinical evidence, by modelers (typically teams made up of clinical and IT experts). This constitutes a novel approach in this area of CIG development, where understandability and modifiability aspects have not been considered to date. Objective: In this paper, w...

Medical guidelines and protocols are documents aimed at improving the quality of medical care by offering support in medical decision making in the form of management recommendations based on scientific evidence. Whereas medical guidelines are intended for nation-wide use, and thus omit medical management details that may differ among hospitals, medical protocols are aimed at local use, e.g., within hospitals, and, therefore, include more detailed information. Although a medical guideline and an associated protocol concerning the management of a particular disorder are related to each other, one question is to what extent they are different. Formal methods are applied to shed light on this issue. A Dutch medical guideline regarding the treatment of breast cancer, and a Dutch protocol based on it, are taken as an example.

The heterogeneity of clinical data is a key problem in the sharing and reuse of Electronic Health Record (EHR) data. We approach this problem through the combined use of EHR standards and semantic web technologies, concretely by means of clinical data transformation applications that convert EHR data in proprietary format, first into clinical information models based on archetypes, and then into RDF/OWL extracts which can be used for automated reasoning. In this paper we describe a proof-of-concept platform to facilitate the (re)configuration of such clinical data transformation applications. The platform is built upon a number of web services dealing with transformations at different levels (such as normalization or abstraction), and relies on a collection of reusable mappings designed to solve specific transformation steps in a particular clinical domain. The platform has been used in the development of two different data transformation applications in the area of colorectal cancer.

Clinical decision-support systems (CDSSs) should be able to interact with the electronic health record (EHR) to obtain the patient data they require. A recent solution for the interoperability of CDSSs and EHR systems consists in the use of a mediated schema which provides a unified view of their two schemas. The use of such a mediated schema requires the definition of a mapping between this schema and the EHR one. In this paper we investigate the use of the SNOMED CT Expression Constraint Language to characterize these mappings.

The paper presents a general object representation for efficient collision detection. Spatial representation is a crucial factor when motion planning is applied to real environments with complex objects, since the efficiency of the collision detection algorithms depends on the spatial representation used for the agents and obstacles in the scene. Our spatial model consists of a hierarchy of representations that

A first extension to a new object representation for robotics and artificial intelligence applications is presented. Particularly, the model is extended to be able to represent prisms generated by sweeping any arbitrary planar shape along a straight line. This is a first step towards an extension of the model to represent generalized cylinders. This extension is more general, and it is an adequate tool for a twofold treatment of robot motion planning
