Clinical guidelines are special types of plans realized by collective agents. We provide an ontological theory of such plans that is designed to support the construction of a framework in which guideline-based information systems can be employed in the management of workflow in health care organizations. The framework we propose allows us to represent in formal terms how clinical guidelines are realized through the actions of are realized through the actions of individuals organized into teams. We (...) provide various levels of implementation representing different levels of conformity on the part of health care organizations. Implementations built in conformity with our framework are marked by two dimensions of flexibility that are designed to make them more likely to be accepted by health care professionals than standard guideline-based management systems. They do justice to the fact 1) that responsibilities within a health care organization are widely shared, and 2) that health care professionals may on different occasions be non-compliant with guidelines for a variety of well justified reasons. The advantage of the framework lies in its built-in flexibility, its sensitivity to clinical context, and its ability to use inference tools based on a robust ontology. One disadvantage lies in its complicated implementation. (shrink)

Outcomes research in healthcare has been a topic much addressed in recent years. Efforts in this direction have been supplemented by work in the areas of guidelines for clinical practice and computer-interpretable workflow and careflow models.In what follows we present the outlines of a framework for understanding the relations between organizations, guidelines, individual patients and patient-related functions. The derived framework provides a means to extract the knowledge contained in the guideline text at different granularities, in ways that (...) can help us to assign tasks within the healthcare organization and to assess clinical performance in realizing the guideline. It does this in a way that preserves the flexibility of the organization in the adoption of the guidelines. (shrink)

The theory of granular partitions (TGP) is a new approach to the understanding of ontologies and other classificatory systems. The paper explores the use of this new theory in the treatment of task-based clinical guidelines as a means for better understanding the relations between different clinical tasks, both within the framework of a single guideline and between related guidelines. We used as our starting point a DAML+OIL-based ontology for the WHO guideline for hypertension management, comparing this (...) with related guidelines and attempting to show that TGP provides a flexible and highly expressive basis for the manipulation of ontologies of a sort which might be useful in providing more adequate Computer Interpretable Guideline Models (CIGMs) in the future.

An important part of the Unified Medical Language System (UMLS) is its Semantic Network, consisting of 134 Semantic Types connected to each other by edges formed by one or more of 54 distinct Relation Types. This Network is however for many purposes overcomplex, and various groups have thus made attempts at simplification. Here we take this work further by simplifying the relations which involve the three Semantic Types – Diagnostic Procedure, Laboratory Procedure and Therapeutic or Preventive Procedure. We define operators (...) which can be used to generate terms instantiating types from this selected set when applied to terms designating certain other Semantic Types, including almost all the terms specifying clinical tasks. Usage of such operators thus provides a useful and economical way of specifying clinical tasks. The operators allow us to define a mapping between those types within the UMLS which do not represent clinical tasks and those which do. This mapping then provides a basis for an ontology of clinical tasks that can be used in the formulation of computer-interpretable clinical guideline models. (shrink)

The prevalence of pain in patients presenting to Emergency Departments has been well documented by both Cordell and Johnston. Equally well documented has been the apparent failure to adequately control that pain. In 1990 Selbst found that patients with long bone fractures received little analgesia in the ED, and Ngai, et al., showed that the under-treatment of pain continued after discharge. In a prospective study, Ducharme and Barber found that up to one third of patients presented with severe pain and (...) were often unrelieved at discharge. Even though specific patient subgroups appear to be at greater risk, all patients are potential victims of oligoanalgesia - the under-treatment of pain. Despite an ever increasing volume of research about pain in emergency medicine, dissemination of relevant information with widespread change in practice patterns has not been witnessed. Recent studies continue to affirm that pain management in the ED is suboptimal. (shrink)

PurposeThe aim of this paper is to assess the complex issue of responsibility in clinical practice. The paper focuses mainly on the relationship between personal- and medical-professional responsibility of practitioners and clinical guidelines.MethodsAfter a theoretical review of the different definitions of responsibility in selected bioethical and biojuridical literature, two recent juridical proceedings concerning medical responsibility from Italian Courts are discussed. Subsequently, a theoretical analysis of the definition of clinical practice guidelines is proposed in order to (...) show their feasibility to assess personal- and medical-professional responsibility.ResultsThe definitions of responsibility and the two Italian cases show the theoretical and practical difficulties of shared assessments of both personal-professional and medical-professional responsibility in clinical practice. Clinical practice guidelines cannot be assumed as an objective code of action stating exactly a rule of conduct in all situations, but as a tool suggesting how to decide what to do in different conditions.ConclusionsResponsibility in clinical practice is such a complex issue to deserve a special ethical assessment. The clinician’s personal-professional responsibility cannot be replaced or reduced by clinical practice guidelines, because medicine is as such a relationship focused on the expertize of practitioners. Nonetheless, a shared approach to different clinical conditions is needed in order to avoid a relativist outcome and protect patients’ and even clinicians’ rights. Formal guidelines (that describe not exactly what to do but how to decide what to do) are proposed as potential useful tool to achieve this aim. (shrink)

Evidence-based medicine relies on the execution of clinical practice guidelines and protocols. A great deal of of effort has been invested in the development of various tools which automate the representation and execution of the recommendations contained within such guidelines and protocols by creating Computer Interpretable Guideline Models (CIGMs). Context-based task ontologies (CTOs), based on standard terminology systems like UMLS, form one of the core components of such a model. We have created DAML+OIL-based CTOs for the tasks (...) mentioned in the WHO guideline for hypertension management, drawing comparisons also with other related guidelines. The advantages of CTOs include: contextualization of ontologies, providing ontologies tailored to specific aspects of the phenomena of interest, dividing the complexity involved in creating ontologies into different levels, providing a methodology by means of which the task recommendations contained within guidelines can be integrated into the clinical practices of a health care set-up.

This paper examines the few, but important legal and coronial cases concerning withdrawing or withholding life-sustaining treatment from severely disabled or critically impaired infants in Australia. Although sparse in number, the judgements should influence common clinical practices based on assessment of “best interests” but these have not yet been adopted. In particular, although courts have discounted assessment of “quality of life” as a legitimate component of determination of “best interests,” this remains a prominent component of clinical guidelines. (...) In addition, this paper highlights the lack of uniform clinical guidelines available to medical professionals and parents in Australia when making end-of-life decisions for severely ill infants. Thus, it is argued here that there is a need for an overarching prescriptive uniform framework or set of guidelines in end-of-life decision-making for impaired infants. This would encourage greater transparency, consistency, and some degree of objectivity in an area that often appears subjective. (shrink)

The paper presents the outlines of an ontology of plans and guidelines, which is then used as the basis for a framework for implementing guideline-based systems for the management of workflow in health care organizations. The framework has a number of special features, above all in that it enables us to represent in formal terms assignments of work-items both to individuals and to teams and to tailor guideline to specific contexts of application in health care organizations. It is designed (...) also to enable implementations to do justice to the fact that the processes carried out in health care organizations may deviate in different ways from the norms set forth in corresponding guideline definitions. This means that implementations built in conformity with the framework will be marked by a type of flexibility that might make them more likely to be accepted by healthcare professionals than are standard guideline-based management systems.

A paramount, yet unresolved issue in personalised medicine is that of automated reasoning with clinical guidelines in multimorbidity settings. This entails enabling machines to use computerised generic clinical guideline recommendations and patient-specific information to yield patient-tailored recommendations where interactions arising due to multimorbidities are resolved. This problem is further complicated by patient management desiderata, in particular the need to account for patient-centric goals as well as preferences of various parties involved. We propose to solve this problem of (...) automated reasoning with interacting guideline recommendations in the context of a given patient by means of computational argumentation. In particular, we advance a structured argumentation formalism ABA+G (short for Assumption-Based Argumentation with Preferences (ABA+) and Goals) for integrating and reasoning with information about recommendations, interactions, patient’s state, preferences and prioritised goals. ABA+G combines assumption-based reasoning with preferences and goal-driven selection among reasoning outcomes. Specifically, we assume defeasible applicability of guideline recommendations with the general goal of patient well-being, resolve interactions (conflicts and otherwise undesirable situations) among recommendations based on the state and preferences of the patient, and employ patient-centered goals to suggest interaction-resolving, goal-importance maximising and preference-adhering recommendations. We use a well-established Transition-based Medical Recommendation model for representing guideline recommendations and identifying interactions thereof, and map the components in question, together with the given patient’s state, prioritised goals, and preferences over actions, to ABA+G for automated reasoning. In this, we follow principles of patient management and establish corresponding theoretical properties as well as illustrate our approach in realistic personalised clinical reasoning scenaria.

The profession of medicine is predicated upon an ethical mandate: first do no harm. However, critics charge that the medical profession’s culture and its public health mission are being undermined by the pharmaceutical industry’s wide-ranging influence. In this article, we analyze how drug firms influence psychiatric taxonomy and treatment guidelines such that these resources may serve commercial rather than public health interests. Moving beyond a conflict-ofinterest model, we use the conceptual and normative framework of institutional corruption to examine how (...) organized psychiatry’s dependence on drug firms has distorted science. We suggest that academic-industry relationships have led to the corruption of the evidence base upon which accurate diagnosis and sound treatment depend. We describe the current dependency corruption and argue that transparency alone is not a solution — and sometimes even produces iatrogenic effects. Furthermore, we argue that the corruption of the evidence base for diagnostic and practice guidelines renders obsolete the traditional informed consent process, and we offer suggestions for reforming this process.

The possibility that industry is exerting an undue influence on the culture of medicine has profound implications for the profession's public health mission. Policy analysts, investigative journalists, researchers, and clinicians have questioned whether academic-industry relationships have had a corrupting effect on evidence-based medicine. Psychiatry has been at the heart of this epistemic and ethical crisis in medicine. This article examines how commercial entities, such as pharmaceutical companies, influence psychiatric taxonomy and treatment guidelines. Using the conceptual framework of institutional corruption, (...) we show that organized psychiatry's dependence on drug firms has led to a distortion of science. We describe the current dependency corruption and argue that transparency alone is not a solution. We conclude by taking the position that the corruption of the evidence base in diagnostic and practice guidelines has compromised the informed consent process, and we suggest strategies to address this problem.

Healthcare professionals are expected to deliver care that is consistent with clinical guidelines. In this article, we show that the English courts are increasingly willing to be persuaded by written guidelines when determining the standard of care in cases of alleged clinical negligence. This reflects a wider shift in the approach taken by courts in a number of common law jurisdictions around the world. However, we argue that written guidelines are still only one element that (...) courts should consider when determining the standard of care. It is possible to deliver perfect care that deviates from professional guidelines and even to deliver negligent care by uncritically following a guideline that is flawed. We further argue that written guidelines are relevant beyond defining the accepted standard of care. This is because the decision to deviate from a guideline suggests the existence of multiple approaches that should be discussed with patients as part of ensuring informed consent. It is therefore likely that written guidelines will become an even more prominent feature of the medicolegal landscape in future years. (shrink)

Background While there are many guidelines on how to make ethical decisions at the end of life, there is little evidence regarding the quality of this sort of ethical guidelines. Objectives First, this study aims to demonstrate the conceptual transferability of the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument for the quality assessment of ethical guidelines. Second, it aims to illustrate the status quo of the quality of guidelines on end-of-life decision-making by using (...) the AGREE instrument in a first practice test. Method The transferability of the AGREE instrument on the quality assessment of ethical guidelines is demonstrated by conceptual analysis. Guidelines on end-of-life decisions in medicine are identified through a systematic search in MEDLINE (from June 1999 to June 2009). The quality of all included guidelines was assessed with a slightly modified AGREE instrument. Results Of 103 guidelines identified, 34 were included as relevant. The majority of the guidelines analysed in this study were assessed as qualitatively insufficient in five out of six AGREE quality domains. A few guidelines demonstrated, however, that a high level of quality in accordance with the AGREE requirements is possible. Conclusion This review concludes that the quality of many ethical guidelines should and can be improved in all quality domains specified by the AGREE instrument. Furthermore, conceptual analysis indicates that a slightly modified AGREE instrument is transferable to the comprehensive evaluation of the quality of ethical guidelines. Nevertheless, future research is needed to improve the assessment of the presentation of the guidelines' normative basis. (shrink)

SummaryThe dichotomy between ‘scientific’ and ‘practical’ approaches to guideline development is false and divisive. Instead we should concentrate on developing mechanisms to develop and implement valid guidelines to improve patient care. The development of valid guidelines requires considerable expertise and is time consuming and expensive. It is most efficiently done at a regional or national level. The implementation of valid guidelines requires local action including the identification and modification of valid guidelines and a coordinated evidence-based implementation (...) strategy (Grimshaw & Eccles 1998).

Introduction: Clinical practice guidelines (CPGs) are an important source of justification for clinical decisions in modern evidence-based practice. Yet, we have given little attention to how they argue their evidence. In particular, how do CPGs argue for treatment with long-term medications that are increasingly prescribed to older patients? Approach and rationale: I selected six disease-specific guidelines recommending treatment with five of the medication classes most commonly prescribed for seniors in Ontario, Canada. I considered the stated aims (...) of these CPGs and the techniques employed towards those aims. Finally, I reconstructed and logically analysed the arguments supporting recommendations for pharmacotherapy. Analysis: The primary function of CPGs is rhetorical, or persuasive, and their means of persuasion include both a display of their credibility and their argumentation. Arguments supporting pharmacotherapy recommendations for the target population follow a common inductive pattern: statistical generalization from randomized controlled trial (RCT) and meta-analysis evidence. Two of the CPGs also argue their treatment recommendations for older patients in this style, while three fail to justify pharmacotherapy specifically for the older population. Discussion: The arguments analysed lack the auxiliary assumptions that would warrant making a generalization about the clinical effectiveness of medications for the older population. Guidelines reason using simple induction, while ignoring important inferential gaps. Future guidelines should aspire to be well-reasoned rather than simply evidence-based; argue from a plurality of evidence; be wary of hasty inductions; appropriately limit the scope of their recommendations; and avoid making law-like, prescriptive generalizations.

This paper presents a pedagogical framework for teaching cross-cultural clinical ethics. The approach, offered at the intersection of anthropology and bioethics, is innovative in that it takes on the “social sciences versus bioethics” debate that has been ongoing in North America for three decades. The argument is made that this debate is flawed on both sides and, moreover, that the application of cross-cultural thinking to clinical ethics requires using the tools of the social sciences within a principles-based framework (...) for clinical ethics. This paper introduces the curriculum and provides guidelines for how to teach cross-cultural clinical ethics. The learning points that are introduced emphasize culture in its relation to power and underscore the importance of viewing both biomedicine and bioethics as culturally constructed. (shrink)
