This paper explores the nature of causation within the framework of evidence‐based practice (EBP) for health care. The aims of the paper were first to define and evaluate how causation is presently accounted for in EBP; second, to present an alternative causal account by which health care can develop in both its clinical application and its scientific research activity. The paper was premised on the idea that causation underlies medical and health care practices and impacts on the way we understand health science research and daily clinical practice. The question of what causation is should therefore be of utmost relevance for all concerned with the science, philosophy and progress of EBP. We propose that the way causation is thought of in contemporaneous health care is exposed by evidential frameworks, which categorize research methods on their epistemological strengths. It is then suggested that the current account of causation is limited in respect of both the functionality of EBP, and its inherent scientific processes. An alternative ontology of causation is provided, which has its roots in dispositionalism. Here, causes are not seen as regular events necessitating an effect, but rather phenomena that are highly complex, context‐sensitive and that tend towards an effect. We see this as a better account of causation for evidence‐based health care.
Evidence-based medicine (EBM) continues to be vigorously debated and person-centered healthcare (PCH) has been proposed as an improvement. But is PCH offered as a supplement to or as a replacement of EBM? Prima facie PCH only concerns the practice of medicine, while the contended features of EBM also include specific methods and the biomedical model. In this paper I argue that there are good philosophical reasons to see PCH as a radical alternative to the existing medical paradigm of EBM, since the two seem committed to conflicting ontologies. I will aim to make explicit some of the most fundamental assumptions that motivate EBM and PCH in order to show that the choice between them ultimately comes down to ontological preference. While EBM has a solid foundation in positivism, or what I here call Humeanism, PCH is more consistent with causal dispositionalism. I conclude that if there is a paradigmatic revolution on the way in medicine, it is first of all one of ontology.
Some of the chief goals of science are understanding, explanation, prediction, and application in new technologies. Only if the world has some significant degree of constancy in what follows from what can these activities be conducted with any purpose. But what is the source of such predictability and how does it operate? This is a question that goes beyond science itself and inevitably requires a philosophical approach. It is argued in such terms that causation is the main foundation upon which the possibility of science rests. But what methods should we adopt in order to identify causes in science? The choice of methods will inevitably reflect what one takes causation to be, making an accurate account of causation an even more pressing matter. The enquiry concerns the correct norms for the empirical study of the world. This matters a lot. Some of the greatest challenges that we face will only be solved if we understand what has caused the problem and what, if anything, could then cause its alleviation.
Medically unexplained symptoms (MUS) remain recalcitrant to the medical profession, proving less suitable for homogenic treatment with respect to their aetiology, taxonomy and diagnosis. While the majority of existing medical research methods are designed for large scale population data and sufficiently homogenous groups, MUS are characterised by their heterogenic and complex nature. As a result, MUS seem to resist medical scrutiny in a way that other conditions do not. This paper approaches the problem of MUS from a philosophical point of view. The aim is to first consider the epistemological problem of MUS in a wider ontological and phenomenological context, particularly in relation to causation. Second, the paper links current medical practice to certain ontological assumptions. Finally, the outlines of an alternative ontology of causation are offered which place characteristic features of MUS, such as genuine complexity, context-sensitivity, holism and medical uniqueness at the centre of any causal set-up, and not only for MUS. This alternative ontology provides a framework in which to better understand complex medical conditions in relation to both their nature and their associated research activity.
