"Every man has his particular way of being in good health" - Emanuel Kant. Emanuel Kant's description of health stands in stark contrast to accepted definitions of health. For example, the WHO defines ‘health’ as ‘a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity’. However, as people get on with day-to-day living, no one can achieve the goal of ‘complete physical, mental and social well-being’. It is odd to define ‘health’ as (...) a negative state that puts it beyond the reach of everyone. This paper explores the idea of health being a personal state, health being the product of every man's particular way of making sense of his particular circumstances. (shrink)

When natural time sequences were replaced by clocks, time became a measurable commodity and the ‘speedy use of time’ a virtue. In medical practice shorter consultations allow more patients to be seen, whereas longer consultations result in a better understanding of the patient and her problems. Crossing the line of time-efficiency and time-effectiveness compromises the balance between short-term turnover and long-term outcomes. The consultation has all the hallmarks of a complex adaptive system whose characteristics are not determined by the characteristics (...) of the components, but by the patterns of interaction among the components. Systems are dynamic and change over time; the dynamic nature is not incidental, but necessary as complex systems operate at conditions far from equilibrium. The central notion when we talk of time and complexity is that of ‘memory’. Memory is carrying something from the past over into the future. Memory is filtered/interpreted, separating noise from information. Memory therefore is not an instantaneous thing, it takes time to develop; it is slow. The dynamics between the participating agents in the consultation will create shared memories that live on to shape future interactions. Shared memories are stronger and contain more relevant knowledge if they are based on frequent interactions and ongoing doctor–patient relationships, leading to a better understanding of the whole person – a process that takes time. Sufficient time, that is, ‘a certain slowness’, is an essential element of the healing relationship in the consultation. It creates a sufficiently stable, but adaptive, environment that can withstand changing demands. Hence a more complete understanding of the consultation and its time demands will not only lead to more effective treatment, it will also humanize a situation which has become to a large extent purely instrumental. This process of humanization is important not only for the patient, but also for the doctor. (shrink)

In this paper we argue that knowledge in health care is a multidimensional dynamic construct, in contrast to the prevailing idea of knowledge being an objective state. Polanyi demonstrated that knowledge is personal, that knowledge is discovered, and that knowledge has explicit and tacit dimensions. Complex adaptive systems science views knowledge simultaneously as a thing and a flow, constructed as well as in constant flux. The Cynefin framework is one model to help our understanding of knowledge as a personal construct (...) achieved through sense making. Specific knowledge aspects temporarily reside in either one of four domains – the known, knowable, complex or chaotic, but new knowledge can only be created by challenging the known by moving it in and looping it through the other domains. Medical knowledge is simultaneously explicit and implicit with certain aspects already well known and easily transferable, and others that are not yet fully known and must still be learned. At the same time certain knowledge aspects are predominantly concerned with content, whereas others deal with context. Though in clinical care we may operate predominately in one knowledge domain, we also will operate some of the time in the others. Medical knowledge is inherently uncertain, and we require a context-driven flexible approach to knowledge discovery and application, in clinical practice as well as in health service planning.

An astonishing volume and diversity of evidence is available for many hypotheses in the biomedical and social sciences. Some of this evidence—usually from randomized controlled trials (RCTs)—is amalgamated by meta-analysis. Despite the ongoing debate regarding whether or not RCTs are the ‘gold-standard’ of evidence, it is usually meta-analysis which is considered the best source of evidence: meta-analysis is thought by many to be the platinum standard of evidence. However, I argue that meta-analysis falls far short of that standard. Different meta-analyses (...) of the same evidence can reach contradictory conclusions. Meta-analysis fails to provide objective grounds for intersubjective assessments of hypotheses because numerous decisions must be made when performing a meta-analysis which allow wide latitude for subjective idiosyncrasies to influence its outcome. I end by suggesting that an older tradition of evidence in medicine—the plurality of reasoning strategies appealed to by the epidemiologist Sir Bradford Hill—is a superior strategy for assessing a large volume and diversity of evidence.

Rationale: The new area of health system research requires a revision of the taxonomy of scientific knowledge that may facilitate a better understanding and representation of complex health phenomena in research discovery, corroboration and implementation. Method: A position paper by an expert group following and iterative approach. Results: ‘Scientific evidence’ should be differentiated from ‘elicited knowledge’ of experts and users, and this latter typology should be described beyond the traditional qualitative framework. Within this context ‘framing of scientific knowledge’ is defined (...) as a group of studies of prior expert knowledge specifically aimed at generating formal scientific frames. To be distinguished from other unstructured frames, FSK must be explicit, standardized, based on the available evidence, agreed by a group of experts and subdued to the principles of commensurability, transparency for corroboration and transferability that characterize scientific research. A preliminary typology of scientific framing studies is presented. This typology includes, among others, health declarations, position papers, expert-based clinical guides, conceptual maps, classifications, expert-driven health atlases and expert-driven studies of costs and burden of illness. Conclusions: This grouping of expert-based studies constitutes a different kind of scientific knowledge and should be clearly differentiated from ‘evidence’ gathered from experimental and observational studies in health system research.

Published research findings are sometimes refuted by subsequent evidence, says Ioannidis, with ensuing confusion and disappointment.

Although typically implicit, clinicians face an inherent conflict between their roles as medical healers and as providers of technical biomedicine (Scott et al. in Philos Ethics Humanit Med 4:11, 2009). This conflict arises from the tension between the physicalist model which still predominates in medical training and practice and the extra-physicalist dimensions of medical practice as epitomised in the concept of patient-centred care. More specifically, the problem is that, as grounded in a "borrowed" physicalist philosophy, the dominant "applied scientist" model (...) exhibits a number of limitations which severely restrict its ability to underwrite the effective practice of care. Moreover, being structural in character, these problems cannot be resolved by piecemeal modifications of the existing model, nor by an appeal to evidence-based medicine (Miles in J Eval Clin Pract 15(6):887-890, 2009; Miles in Folia Med 55(1):5-24, 2013; Miles et al. in J Eval Clin Pract 14(5):621-649, 2008). Hence, the need for medical theorists to "partner with experts in the humanities to build a sui generis philosophy of medicine" (Whatley in J Eval Clin Pract 20(6):961-964, 2014, p. 961). In response, the present paper seeks to vindicate the merits of hermeneutically-informed template in providing the requisite grounding. While capable of correcting for the limitations of the applied scientist model, a hermeneutically-informed template is a "both/and" approach, which seeks to complement rather than exclude the physicalist dimension, and thereby aspires to reconcile technical mastery with patient-centred care, rather than eschew one in favour of the other. As such, it can provide a cogent philosophical template for current best practice, which does justice to the art as well as the science of medical care. (shrink)
