In this paper, we propose an approach for managing clinical guidelines. We outline a modular architecture, allowing us to separate two conceptually distinct aspects: the representation (and acquisition) of clinical guidelines and their execution. We propose an expressive formalism, which allows one to deal with the context-dependent character of clinical(More)
In this paper, we present GLARE, a domain-independent prototypical system for acquiring, representing and executing clinical guidelines. GLARE has been built within a 7-year project with Azienda Ospedaliera San Giovanni Battista in Turin (one of the largest hospitals in Italy) and has been successfully tested on clinical guidelines in different domains,(More)
The hepatic clearance of D-sorbitol, a natural polyol which is metabolized by the liver, was studied in normal and cirrhotic subjects after bolus intravenous injection (2 g) and during constant infusion (54 mg/min) with the aim of providing a noninvasive and simple measure of functional liver plasma flow. The high hepatic extraction of D-sorbitol and the(More)
We present GLARE, a domain-independent system for acquiring, representing and executing clinical guidelines (GL). GLARE is characterized by the adoption of Artificial Intelligence (AI) techniques in the definition and implementation of the system. First of all, a high-level and user-friendly knowledge representation language has been designed. Second, a(More)
The adaptation of clinical guidelines to specific contexts is a fundamental task to promote guideline dissemination and use. Several aspects of contextualization need to be faced, including the adaptation of guidelines to local resource availability and (for computer-based guideline approaches) to local software environment. We show how a computer-based(More)
GLARE (GuideLine Acquisition, Representation and Execution) is a domain-independent system for the acquisition, representation and execution of clinical guidelines. GLARE is unique in its approach to supporting the decision-making process of users/physicians faced with various alternatives in the guidelines. In many cases, the best alternative cannot be(More)
A diagnostic protocol was studied, designed to evaluate the main parameters of liver circulation in man. A water solution ofd-sorbitol (S) and indocyanine green (ICG) was infused intravenously in six controls and nine cirrhotics. Steady-state renal and hepatic S clearances as well as hepatic ICG clearance were calculated. In controls the values (mean ±sd)(More)
In our previous work, we proposed a domain-independent language to describe clinical guidelines and a graphical tool to acquire them. In this paper, we describe an approach to execute clinical guidelines. We propose a flexible execution engine that can be used in clinical decision support applications, and also for medical education, or for integrating(More)
One of the most relevant obstacles to the use and dissemination of clinical guidelines is the gap between the generality of guidelines (as defined, e.g., by physicians' committees) and the peculiarities of the specific context of application. In particular, general guidelines do not take into account the fact that the tools needed for laboratory and(More)
In this paper, we propose an approach for managing clinical guidelines. We sketch a modular architecture, allowing us to separate conceptually distinct aspects in the management and use of clinical guidelines. In particular, we describe the clinical guidelines knowledge representation module and we sketch the acquisition module. The main focus of the paper(More)
