The classical complexity theory focus on explanation aligns with a positivist epistemology, where knowledge is valued if it is generalizable and allows us to predict, and manipulate, future behavior [25]. Article  PubMed Google Scholar. The complexity philosophy—a myriad of continuously interacting elements in an open system—allows an innovative methodological turn by blending diverse bodies of knowledge (Gear et al., 2017; McDaniel et al., 2009). 2014;45:119–26. Biologically speaking, health or life in general could be thought of as a state of negative entropyÂ, This may be simply thought of as the biological manifestation of entropy in progress. We subsequently outline how, by applying the twin lenses of complexity theory and pragmatism, we developed a deeper understanding of the processes of implementation. Phase changes: Where a small change in the system inputs results in a qualitative change in the system’s state. sympathetic, parasympathetic and humoral)Â, Subject to the same limitations as time domain analysisÂ, Statistical technique whereby the degree of connectivity between data sets is quantifiedÂ, Principle advantage over other methods is its ability to be applied to shorter, ‘noisier’ data setsÂ, Copyright © 2020 The British Journal of Anaesthesia Ltd. Sanderson I. There are two pervasive issues with defining a social system, nesting and fuzzy boundaries, both of which are implicated in, and complicate, complexity research [19]. Reject reductionist science in favor of the study of whole systems, in context, Understand research as a continual learning process, Focus on the social consequences of research and intervention, Value the democratization of knowledge and research, valuing all stakeholders’ input, Prioritize understanding over theoretical or methodological purity, encouraging the use of multiple methods. Extensive practical applications of the theoretical concepts outlined in these articles have been described and published, and support consideration of more widespread application (2-5). By starting from a pragmatic epistemology, we allowed our focus to be drawn to the most relevant ontology and methodologies for the study of this implementation. The 3-year research project aimed to develop simulation models to provide strategic decision support for a senior leadership group (SLG) in a large public mental health service (MHS) in Australia. Likewise, any variation in practice from a predetermined norm can be eliminated via the imposition of protocols and guidelines which can be fitted into the machine rather like new spark plugs on a car. Thus, rather than rejecting the reductionist approach of classic complexity theory [20], pragmatism allows for the contribution of both quantitative and qualitative methods in addressing the research question. Brailsford SC. Br Med J. HRV therefore provides us with a window into complex systems and may represent a novel means of monitoring and identifying critically ill patients; of particular note is the fact that these changes appear to precede the clinical manifestation of disease by several hours. Overcoming the barriers to implementation of operations research simulation models in healthcare. This approach meant that our image of individual events was often incomplete, preventing us from accurately identifying the role of individual agency in the observed interactions and system-level changes. The healthcare system has proved a challenging environment for innovation, especially in the area of health services management and research. Both pragmatism and complexity theory also encourage a focus on the interactions of knowledge systems, and the study of how these intersections are negotiated [4, 44, 48]. Health Care Manage Sci. Complexity thinking is increasingly being embraced in healthcare, which is often described as a complex adaptive system (CAS). IEEE. Proceedings of the 2012 Winter Simulation Conference. J Health Serv Res Policy. PDF | On Oct 1, 2001, Paul E Plsek and others published The Challenge of Complexity in Health Care | Find, read and cite all the research you need on ResearchGate A review on the relation between simulation and improvement in hospitals. Emergence as a construct: history and issues. A key feature of pragmatism is the contextualization of knowledge [44, 45]. In healthcare, these systems level outcomes represent public health interests such as the efficiency and effectiveness of healthcare delivery, the population’s quality of life, and rates of disease morbidity and mortality. The loss of biological variability, with an attendant increase in entropy, is characteristic of several disease states, including MODS and even normal ageing.6 Therefore, although MODS represents an example of a complex system, it may also be viewed as a higher entropy state than health and therefore as a step on the decomplexification pathway that may lead ultimately to death (Table 2). 151–2). Brailsford SC, Bolt TB, Bucci G, Chaussalet TM, Connell NA, Harper PR, Klein JH, Pitt M, Taylor M. Overcoming the barriers: a qualitative study of simulation adoption in the NHS. Its emergence provides credence to the growing arguments from health services researchers, namely that the healthcare system contains a level of complexity qualitatively different to other systems due to the social nature of health, and therefore requires a different set of research methods [1,2,3,4]. Kernick D. Wanted – new methodologies for health service research. Eval Program Plann. 2001;3(1):5–23. Another limitation is posed by the theoretically agnostic position of pragmatism, as outlined above. Rockwell Automation. Emergence. Complexity theory has been used to study different aspects of healthcare, including management , continuity of care , nursing , and decision-making . Tunnicliffe-Wilson JC. We found this to be a key challenge in our project. These complex systems can include both the natural world, human/animal relationships, as well as the organization of businesses. One of the more promising alternatives comes from Byrne et al.’s [20] application of complex realism to complexity theory. Complexity theory can be both an ontology for quantitative approaches and a metaphor for qualitative approaches. The challenge exists therefore to identify decomplexification before it becomes irreversible. Changes in the SLG were unpredictable and non-linear, instead emerging from what may be considered phase changes in the system. Whether we are experts on complexity theory or not (and most of us are not), we know in our bones that delivering high-quality services in such a complex environment will not be achieved merely by following a standard operating procedure, inserting the results of a randomised controlled trial or adopting the seven habits of highly successful people. However, empirical evidence that this lens has been useful in designing health care remains elusive. Herein, we described a too-familiar experience in health services implementation – a constantly changing implementation context– followed by a discussion of how complexity theory and pragmatism provide complementary approaches to the difficulties in evaluating such implementations. The appropriation of complexity theory in health care. In our project, the response to the challenge of working within this particular CAS manifested through the emergent formulation of two deeply pragmatic research questions: How can we (the researchers) help to improve strategic decision-making for mental health services? We then explore the possibilities of using pragmatism to provide the missing epistemological foundation required to structure the study of social complexity theory in healthcare. McDermott F. Complexity theory, trans-disciplinary working and reflective practice. Both the SLG and the researchers exhibited adaptation and co-evolution, changing strategic priorities and approaches based on the changes in context. All modes of experience, including research, are treated as interventions [42]. The normal, healthy human heart rate displays fractal variation which is lost in numerous disease states. By using complexity theory as a lens for making sense of interactions, this study proposes a nine-step framework for assessing and influencing KPs planned, under way, and completed. We also faced difficulties in that time and access limitations of working with senior managers often meant that data were not collected when significant decisions were made or events occurred. For pragmatism, knowledge is only meaningful when coupled with action [38]. This article introduces the field of complexity science, what it means in practice, and in the experience of others, and myself in applying complexity theory to improving health. We discuss the similarities between complexity theory and pragmatism, and close by revisiting our experiences putting pragmatic complexity theory into practice. Cordery A. As an example, one might consider how the best way to reduce anaesthetic drug errors within a theatre complex might be achieved. The redefinition of local rules as human instincts, constructs, and mental models has also been subject to debate [5, 39]. Cite this article. Los Angeles, CA: SAGE Publications; 2010. p. 95–118. As we discovered in our efforts to develop simulation models of mental health patients, a patient may pass through multiple different practices, hospitals, and even districts over an episode of care, interacting with scores of individual agents, each operating in a different context. This is in part due to the inherent problems with trying to measure internal states, with even qualitative methods heavily reliant on individual insight and candor [21]. Bragg M. BBC Radio 4; 2005., DOI: R Tuffin, BSc (Hons) MRCP FRCA EDIC FFICM PGCCE, Consultant in Anaesthesia and Intensive Care Medicine, Harrogate and District NHS Foundation Trust, Lancaster Park Road, Harrogate HG2 7SX, UK. HRV monitoring has already demonstrated its utility as a means of predicting patients at risk of developing postoperative cardiac failure or increased mortality post-myocardial infarction;3 however, the challenge now remains to refine the technique so as to be amenable to real-time bedside monitoring. University Park: Pennsylvania State University Press; 2012. In: accelerating quality improvement in health care: strategies to accelerate the diffusion of evidence-based innovations. The nurse has been taught to consider interpersonal relationships and see an entire community as a “client”. We suggest that what is needed is a clear epistemology [4], and we suggest that pragmatism may provide the epistemological foundations required to structure the study of social complexity theory in healthcare. 1999;1(1):49–72. The planned modeling approach was discrete-event simulation using the ARENA® software package [11]. The commonalities between pragmatism and complexity theory are striking, and include a sensitivity to research context, a focus on applied research, and the valuing of different forms of knowledge. London: Continuum. It is highly likely that a pragmatic approach will not always support the application of complexity theory in healthcare implementation research. This review assesses whether it is possible to reliably capture evidence for efficacy in results or process within interventions that were informed by complexity science and closely related conceptual … CAS  Indeed, the mismatch between this hypercomplexity [1] and the dominant mechanistic conception of healthcare [5, 6] has been used as a key explanation for the lack of implementation of evidence-based medicine [4, 7] and healthcare innovation [6, 8,9,10]. The use of complexity science provides nurses with a language that liberates them from the reductionist view … Many of these features of a CAS were found in our experiences. However, these approaches have had limited success in healthcare, with low rates of modeling implementation [22,23,24] often being attributed to the lack of good data from which to build models [25,26,27,28]; the complex social and organizational context of healthcare, with multiple intersecting and nested stakeholder groups [1, 2, 25, 27, 29, 30]; and the high expertise and time costs of creating sufficiently complex, ecologically valid models [25,26,27,28,29, 31,32,33]. It also allows for different definitions of complexity theory. Social complexity theorists seem to disagree, describing emergence as descriptive, not explanatory [40], and arguing that the only way to see the outcome of a CAS is to observe the system as a whole, rather than its component individual agents or models [5]. In a healthy individual, the inter-beat variation, as measured by the R–R interval, fluctuates in a stable manner that is hypothesized to be due to the influence of biological ‘strange attractors’ (Table 2).4 In plain English, this means that the heart receives information from other organs, including the sympathetic nervous system and various endocrine glands while also being affected by changes in breathing and posture; an ability to respond to these (and therefore show variability) is clearly a requirement for normal homeostasis. The case study discussed here presents the researcher experience of the implementation process, which ultimately shaped and motivated the epistemological quest that is the subject of this paper.
