Are case reports valuable? Exploring their role in evidence based medicine and patient care

Case reports, often overlooked in evidence-based medicine (EBM), play a pivotal role in healthcare research. They provide unique insights into rare conditions, novel treatments, and adverse effects, serving as valuable educational tools and generating new hypothesis. Despite their limitations in generalizability, case reports contribute significantly to evidence-based practice by offering detailed clinical information and fostering critical thinking among healthcare professionals. By acknowledging their limitations and adhering to reporting guidelines, case reports can contribute significantly to medical knowledge and patient care within the evolving landscape of EBM. This editorial explores the intrinsic value of case reports in EBM and patient care.

Beyond continental and African philosophies of personhood, healthcare and difference

In this study, I explore the challenges that ideological hegemonies of personhood imbibed by nurses and other healthcare workers could pose for the nursing profession, particularly in terms of inhibiting the acknowledgment of difference. Dominant or hegemonic conceptions of personhood in particular spaces often consist of self‐contained ideas and essentialist ontologies and normativity of what it means to be a person, lack of which results in the denial of personhood and the othering as non‐person or sub‐person. The other as the residue of such self‐contained notions of personhood is most often denied the quality of care that the one who fits within such conceptions enjoy. For nurses and other healthcare workers to overcome such exclusionary tendencies in healthcare, they must overcome hegemonies and ideological dominance and be more open to alternative viewpoints and theories of personhood. I develop these lines of thought by focusing on the rich ideological traditions of Continental and African philosophies showing how exclusion takes place within these traditions based on conceptions of personhood and how such exclusion on the basis of difference impacts negatively on healthcare. I conclude by highlighting the need to go beyond hegemonic philosophies of personhood by decolonizing and demasculinizing healthcare, thereby allowing difference to flourish in an ecology of medical knowledge.

An epistemological problem for integration in EBM

Evidence-based medicine (EBM) calls for medical practitioners to "integrate" our best available evidence into clinical practice. A significant amount of the literature on EBM takes this integration to be unproblematic, focusing on questions like how to interpret evidence and engage with patient values, rather than critically looking at how these features of EBM can be implemented together. Other authors have also commented on this gap in the literature, for example, identifying the lack of clarity about how patient preferences and evidence from trials is supposed to be integrated in practice. In this paper, I look at this issue from an epistemological perspective, (looking at how different types of knowledge in EBM can be used to make sounds judgements). In particular, I introduce an epistemological issue for this integration problem, which I call the epistemic integration problem. This is essentially the problem of how we can use information that is both general (eg, about a population sample) and descriptive (eg, about what expected outcomes are) to reach clinical judgements that are individualized (applying to a particular patient) and normative (about what is best for their health).

"Personal Knowledge" in Medicine and the Epistemic Shortcomings of Scientism

In this paper, we outline a framework for understanding the different kinds of knowledge required for medical practice and use this framework to show how scientism undermines aspects of this knowledge. The framework is based on Michael Polanyi's claim that knowledge is primarily the product of the contemplations and convictions of persons and yet at the same time carries a sense of universality because it grasps at reality. Building on Polanyi's ideas, we propose that knowledge can be described along two intersecting "dimensions": the tacit-explicit and the particular-general. These dimensions supersede the familiar "objective-subjective" dichotomy, as they more accurately describe the relationship between medical science and medical practice. Scientism, we argue, excludes tacit and particular knowledge and thereby distorts "clinical reality" and impairs medical practice and medical ethics.

Philosophical inquiry and the goals of nursing: a critical approach for disciplinary knowledge development and action

Philosophical inquiry remains critically important for nursing education, practice, and knowledge development. We propose a 3-level taxonomy of philosophical inquiry to guide nursing curricula and research development. Important background information about philosophy and the development of philosophical methods is given. Then philosophical inquiry is linked to the goals of nursing using our proposed taxonomy: level I-cultivating an attitude of "critical consciousness" related to all nursing situations and actions, level II-analysis and application of philosophical perspectives to nursing problems and level III-generating new knowledge for nursing purposes including new theories of practice and research.

Decontextualized versus lived worlds: critical thoughts on the intersection of evidence, lifeworld, and values

BACKGROUND

Numerous studies and trials are conducted under the evidence-based complementary and alternative medicine (EBCAM) paradigm. Some individuals view the results generated by this approach as symbolic evidential proof of complementary medicine, and as representative of practice. Such evaluations are made even though the ability to capture and reflect clinical reality by the methods used is questioned. The effect of this type of research on complementary medicine researchers and practitioners has received minimal consideration, and this article explores this subject by critically reviewing the literature and theorizing the effects on the lifeworld and values of those embodied by EBCAM.

METHODS

This review accesses the discourse of various disciplines involved with, and commenting on, complementary medicine research. Collected literature is collated within specified limits, subjected to argumentation analysis, and synthesized within a critical theory methodology. Emergent themes are examined, and the effects of EBCAM on holistic researcher and practitioner lifeworld and values are theorized via the colonization framework of critical social theorist Jürgen Habermas.

RESULTS

The use of an evidence-based medicine research model to investigate complementary medicine practice is not well regarded by those who critically examine its use. Within a critical theory framework, the generation and application of research resulting from EBCAM is viewed as a philosophically incongruent process arising from a dominative discourse that can colonize lifeworld. This can result in a variety of pathological symptoms that may have a detrimental effect.

CONCLUSIONS

The application of EBCAM has the theoretical potential to damage complementary medicine culture, profession, and practice. Its ongoing use requires thought, attention, and careful revision, taking into account the lifeworld and values of researchers and practitioners. If this inclusive view can occur, knowledge generation with relevance to the whole of the professions could proceed.

Twelve tools for teaching medical students

OBJECTIVE

The aim of this paper is to outline strategies for teaching psychiatry to medical students. The background is that today's medical students are tomorrow's doctors. Undergraduate psychiatry teaching provides us a unique opportunity to instil positive attitudes, knowledge and skills in the medical workforce of the future. Moreover, teaching has many positives for the individual clinician, their service and the community.

CONCLUSIONS

We outline 12 strategies that we find makes teaching not only enjoyable for us, but engaging, memorable and relevant for students.

Polanyi's tacit knowing and the relevance of epistemology to clinical medicine

Most clinicians take for granted a simple, reductionist understanding of medical knowledge that is at odds with how they actually practice medicine; routine medical decisions incorporate more complicated kinds of information than most standard accounts of medical reasoning suggest. A better understanding of the structure and function of knowledge in medicine can lead to practical improvements in clinical medicine. This understanding requires some familiarity with epistemology, the study of knowledge and its structure, in medicine. Michael Polanyi's theory of tacit knowing is advanced as the basis for developing a more accurate understanding of medical knowledge. Tacit knowing, which explores the taken-for-granted background knowledge that underlies all human knowing, is explained in detail with a focus on its relevance for clinical medicine. The implications of recognizing tacit knowing in medicine and medical decisions are discussed. These include the ability to explain the importance of the clinical encounter in medical practice, mechanisms for analysing patient and doctor as persons, and the need for humility given the uncertainty that the tacit dimension injects into all medical decisions. This more robust medical epistemology allows clinicians to better articulate the nature and importance of patient-centred care, to avoid pitfalls inherent in reductionist approaches to medical knowledge, and to think more clearly about the relationships between medicine and health care at the individual and population levels.

'We hold these truths to be self-evident': deconstructing 'evidence-based' medical practice

Rationale, aims and objectives Evidence-based medicine (EBM) claims to be based on 'evidence', rather than 'intuition'. However, EBM's fundamental distinction between quantitative 'evidence' and qualitative 'intuition' is not self-evident. The meaning of 'evidence' is unclear and no studies of quality exist to demonstrate the superiority of EBM in health care settings. This paper argues that, despite itself, EBM holds out only the illusion of conclusive scientific rigour for clinical decision making, and that EBM ultimately is unable to fulfil its own structural criteria for 'evidence'. Methods Our deconstructive analysis of EBM draws on the work of the French philosopher, Jacques Derrida. Deconstruction works in the name of justice to lay bare, to expose what has been hidden from view. In plain language, we deconstruct EBM's paradigm of 'evidence', the randomized controlled trial (RCT), to demonstrate that there cannot be incontrovertible evidence for EBM as such. We argue that EBM therefore 'auto-deconstructs' its own paradigm, and that medical practitioners, policymakers and patients alike ought to be aware of this failure within EBM itself. Results EBM's strict distinction between admissible evidence (based on RCTs) and other supposedly inadmissible evidence is not itself based on evidence, but rather, on intuition. In other words, according to EBM's own logic, there can be no 'evidentiary' basis for its distinction between admissible and inadmissible evidence. Ultimately, to uphold this fundamental distinction, EBM must seek recourse in (bio)political ideology and an epistemology akin to faith.

Where is the wisdom? I--a conceptual history of evidence-based medicine

Rationale Evidence-based medicine (EBM) has been acclaimed as a major advance in medical science, but criticized as a proposed alternative model for the practice and teaching of medicine. Ambiguity regarding the proper role of the contributions of EBM within the fabric of medicine and health care has contributed to this discrepancy. Aims and objectives We undertook a critical review of the history of the EBM movement, beginning with its origins in the 1970s and continuing through this century. We drew upon the results of an independent project that rationalized the EBM domain from the perspective of educational evaluation and assessment. We considered the content of EBM in relationship to the propositions and promises embodied in advocacy publications. Results EBM emerged in the context of the explosion of biomedical information in the decade preceding public access to the Internet in the mid-1990s and drew upon the independently derived 'information literacy' formula developed by information scientists during the 1980s. The critically important content and achievements of EBM are fully explained within the confines of the information literacy model. The thesis that EBM offers an alternative paradigm for individualized health care, asserted in the advocacy literature, is not supported by published models of evidence-based clinical practice. Conclusion A critical historical review of the origins, content and development of the EBM movement proposes that full integration of the fruits of the movement into routine clinical care remains a conceptual and practical challenge.

Inequities in health and healthcare viewed through the ethical lens of critical social justice: contextual knowledge for the global priorities ahead

The authors use the backdrop of the Healthy People 2010 initiative to contribute to a discussion encompassing social justice from local to national to global contexts. Drawing on findings from their programs of research, they explore the concept of critical social justice as a powerful ethical lens through which to view inequities in health and in healthcare access. They examine the kind of knowledge needed to move toward the ideal of social justice and point to strategies for engaging in dialogue about knowledge and actions to promote more equitable health and healthcare from local to global levels.

Clinical intuition versus statistics: different modes of tacit knowledge in clinical epidemiology and evidence-based medicine

Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is demonstrated through analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine's epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi's theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine.

'A local habitation and a name': how narrative evidence-based medicine transforms the translational research paradigm

RATIONALE

We propose narrative evidence-based medicine as a necessary elaboration of the NIH translational research roadmap. The roadmap defined two complex obstacles, T1 and T2, to the progress of research from the 'bench' or basic laboratory science to the 'bedside' or clinical application, the traversal of which requires emergence of complex transformative relationships between the parties and stakeholders. It fails to encompass patient interactions, hesitancies and alliances with medical care.

AIMS AND OBJECTIVES

We suggest a third transformative or translational step, T3, that begins at the point that practitioners have themselves elected to adopt and recommend strategies and interventions based on high-level evidence and guidelines. In our model, T3 encompasses all aspects of care that converge on the practitioner-patient relationship and ultimately determine what therapies and choices patients actually make regarding their care.

RESULTS

Learning from the biopsychosocial model, patient-centred care and shared decision making while attending to the ethical injunction of Emmanuel Levinas to know the other, we have developed a medical practice and theory that unites the local and specific concerns of narrative medicine with the generalizability and power of evidence-based medicine.

CONCLUSIONS

We offer innovative approaches to study, teach and improve the therapeutic intimacy and integrative effectiveness of the practitioner-patient relationship.

User-driven health care - answering multidimensional information needs in individual patients utilizing post-EBM approaches: a conceptual model

Evidence based on average patient data, which occupies most of our present day information databases, does not fulfil the needs of individual patient-centred health care. In spite of the unprecedented expansion in medical information we still do not have the types of information required to allow us to tailor optimal care for a given individual patient. As our current information is chiefly provided in disconnected silos, we need an information system that can seamlessly integrate different types of information to meet diverse user group needs. Groups of certain individual medical learners namely patients, medical students and health professionals share the patient's need to increasingly interact with and seek knowledge and solutions offered by others (individual medical learners) who have the lived experiences that they would benefit to access and learn from. A web-based user-driven learning solution may be a stepping-stone to address the present problem of information oversupply in medicine that mostly remains underutilized, as it doesn't meet the needs of the individual patient and health professional user. The key to its success would be to relax central control and make local trust and strategic health workers feel more engaged in the project such that it is truly user-driven.

Viewpoint: envisioning the successful integration of EBM and humanism in the clinical encounter: fantasy or fallacy?

Some authors challenge the dominance of evidence-based medicine (EBM) in current medical practice because of its tendency to disregard the patient in the clinical process and thus distort the clinician's view of the patient as the primary focus. This tendency to "scientize" the clinician-patient encounter threatens to seriously reduce the role of humanistic elements in medicine. Although the pendulum shift toward the epistemology of EBM is worrisome, it is only one aspect of the problems facing modern medicine in the process of discovering-or rediscovering-the human dimension in medical care. The author uses his own and others' interpretation of the philosophy of an underappreciated thinker, Michael Polanyi, as a springboard to envision the research required for the development of models of medical education and clinical practice that appropriately acknowledge both EBM and humanism. Striking the right balance between these two elements will require much additional research, but those who simply demonize EBM as the major barrier to humanistic practice fail to appreciate the essential role for critical thinking in responding to the demands of patient safety and health care quality. All may agree that the current medical landscape needs immediate attention but this author argues that such work needs to use the available tools such as EBM and Polanyi's Theory of Tacit Knowing as well as products of future research efforts. Failure to do less will prevent us from reaching the ideal of a truly humanistic encounter firmly embedded in practices that maximize patient safety and health care quality.

Somatic awareness in the clinical care of patients with body distress symptoms

The purpose of this paper is to provide primary care physicians and medical specialists with an experiential psychosomatic framework for understanding patients with body distress symptoms. The framework relies on somatic awareness, a normal part of consciousness, to resolve the dualism inherent in conventional multidisciplinary approaches. Somatic awareness represents a guiding healing heuristic which acknowledges the validity of the patient's physical symptoms and uses body sensations to identify the psychological, physiological, and social factors needed for symptom self-regulation. The experiential approach is based on psychobiologic concepts which include bodily distress disorder, central sensitization, dysfunctional breathing, and contextual nature of mood.

Lung cancer screening: has there been any progress? Computed tomography and autofluorescence bronchoscopy

PURPOSE OF REVIEW

Advances in imaging technologies are currently being explored in the attempt to reduce lung cancer morbidity and mortality by achieving stage shift. We reviewed recent important publications on lung cancer screening.

RECENT FINDINGS

Autofluorescence bronchoscopy has established its important role in the intervention of early central airway lesions. Multidetector computed tomography (CT) and CT-positron emission tomography may facilitate diagnosis of early parenchymal lung lesions. Practical implications of screening are reaching far beyond early diagnostic efforts per se as lead-time, length-time, overdiagnosis biases combined with low specificity of screening tests undermine its cost-effectiveness in the era of healthcare budget constraints.

SUMMARY

Advanced imaging technologies may allow early detection and prudent intervention in some individuals that harbour asymptomatic early lung cancer, but disproportional expenses may be required to sieve out many more individuals at risk to attain stage shift. Confounding co-morbidities and practical hurdles may reduce screening's efficacy as it is plausible that for the majority of smokers, lung cancer may not be the ultimate cause of suffering since 90% of them will not develop lung cancer. This fact remains true despite increased use of noninvasive and minimally invasive technologies for the maximum preservation of quality of life irrespective of whether early intervention is a success or failure.
