How the built environment in healthcare influences output in terms of patient safety, efficiency, quality of care, staff turnover, total economy etc, is often overlooked. Perhaps this is because hospitals are different to “normal” companies; the building and the operation in public owned institutions in complex welfare models is often organised in separate political, managerial and budget systems. But in the present state of massive resource scarcity added to increased globalisation, we need to rethink and redesign the concept of healthcare and hospitals as extremely complex and dynamic systems.
It is pivotal to learn how to catalyse all available determinants if we want the future state of healthcare in Europe to be signified by cutting edge business models of maximum quality and efficiency. This need might explain the increasing interest in evidence-based design (EBD). The purpose of this article is to explain and discuss how EBD can contribute developing a European language and shared methods to innovate healthcare.
The European attitude towards EBD can be described as ambiguous at least. I am concerned that this ambiguity towards EBD – as we experience in Scandinavia - is consuming focus and energy that instead could be used for more structured and open-minded debates leading to a development of a European concept of EBD. Such a concept could be a tool to benchmark various governmental models and systems of healthcare aiming towards innovative and sustainable solutions for modern healthcare. The discussion on EBD seems to be more focused on terminology than on substance. One risk related to such a discussion is that while we discuss whether we believe in EBD or not patients die, staff get injured and money spent on healthcare does not offer optimum payoff in terms of quality and efficiency. Another risk is that the trend towards generic global standards will threaten a dynamic development of national, context-based and innovative solutions necessary to cope with the ever-changing environment of healthcare.
The Pros and Cons
The topic of EBD is an inviting battlefield for hospital managers, architects and consultants with their often, strong opinions. Some say “old wine in new bottles” – we have always done it the EBD-way although we do not write research reports, guidelines and manuals. Others refuse to use evidence that is still young and to some extent scientifically premature. And then there are those who – using strict logic – claim, that design and architecture is tied to the context and culture that it is embedded in and therefore it is impossible to use what is considered to be proven evidence from another country like the US. The latter argument is often stated in the local European debate on hospital innovation due to the undisputed large diversity between national models of healthcare.
Those who claim to embrace and perform EBD often fail when the magnifier of methodology and scientific investigation is set to assess the strength of the conclusions and the possibility for generalisations. Many perform EBD as if it is only a matter of healing gardens that can be seen from the bedside of the patient, single patient-rooms and famous artwork in the lobby. Most often pre- and post-occupancy data are completely missing, making it impossible to compute the actual result of the change in design. Finally, many EBD processes have a total lack of coherent, multidisciplinary and transparent methodology in design, making it difficult to navigate and impossible to assess universal perspectives.
Stop the Battle – it Kills Patients and
I say: stop the theoretical discussion and jump to a higher level of debate. The fact is many patients are hurt and killed by safety issues in the built environment due to the negligence of relations between the physical environment and what goes on in-between the walls. Many patients and relatives have bad experiences of the buildings and rooms. However, they choose to accept and silently adjust to the circumstances as if a hospital stay is something that must be endured and survived – and not be enjoyed in a healing, meaningful and comfortable way. On their part, staff often struggle with stress, and the challenge of delivering high-performance care despite bad design and a chaotic organisation.
Common to all of the above scenarios is that neglecting the consequences is damaging on several levels. First: irrespective of your position in healthcare – as owner, manager or staff – you are in a business that can either heal or hurt others in your custody. Herein lies a responsibility to contribute with whatever works from a combination of available resources and methods for the individual patient – this is the ethical part of the game. Second: it’s pivotal that money – often in EU countries the tax payer’s money – spent on healthcare is invested in a way attributing most value in terms of health and healing patients. The balance between efficiency and quality must not be “either/or”, but work as twins in a coherent sustainable system.
The New Paradigm
The new paradigm of healthcare innovation and hospital business models is that hospitals consist of five main components: building, equipment, human activity, infrastructure and logistics – understood as handles on the machine or keys on the keyboard. These must be constantly kept in optimum synergy in an ever-changing context of scarce resources, shifting demands and technological developments. This new paradigm will catalyse the potential for optimum health and efficiency; the methods of evidence-based design can serve as tools.
But a theoretical paradigm is not enough. What we need to address, from my Scandinavian position, is the structure and sense of ownership that works as a secondary foundation of incentives and systems for strategic and managerial decisionmaking. In a matrix way of categorising the various types of ownerships, the early start of the USA in the research fields of EBD may be explained by the simpler, single-owner model where the focus on output-responsibility in the market is obvious. At the other end is the publicly owned hospital, where the owners are “you and I “ in the shape of a bulky bureaucracy and diffuse groups and sectors. This is often the model in much of the EU, making it challenging to responsibly lead and manage hospitals as coherent and sustainablebusinesses.
The Theory of Evidence-Based Design
Many mix up the concepts of EBD and healing architecture. The simple differentiation is that evidence-based design is a method to obtain healing architecture. But EBD can do more than provide healing architecture. The focus of EBD is optimising the value of the desired outputs. These can be healing architecture, but can also be low energy, high ambulatory efficiency, low staff turnover or lean processes. It depends on the specific strategy plan of the business model and the measures chosen to assess the success or performance.
Because of the high level of complexity in healthcare and design we need to move the discussion from rigid theoretical discussions often focused on the battle between qualitative and quantitative research paradigms and accept EBD with a more multidisciplinary approach, first and foremost as a tool developing a common language. This will enable us to benchmark the mechanisms in different complex systems that can explain for different outputs. Performed in the framework and relations between EU counties and with an open, collaborative attitude to global trends and communities, the door to real healthcare innovation is open.
The discourse of EBD is still signified by its novelty as research paradigm although the vocabularies in terms of definitions and tools are increasing. Again the “first movers” from overseas are trying to lead the way. Since 2009 the certification and accreditation of EBD as a process or method – EDAC (Evidence-Based Design Accreditation Certification) has been a possible “school” of practice. Yet we are only 385 people worldwide who are certified, mainly from the US. The distribution also shows a majority of architects and designers, with a lack in the presence of healthcare executives and hospital managers.
EDAC offers a methodology and hereby a framework for mutual understanding and a platform for co-creation of both a common language and future solid evidence. EDAC is not a rigid system, but a place to start the journey and is open for meaningful change of methods as long as EBD can be improved.
Yes, EDAC was born in the US and with close inspection of the current methodology we could dismiss its relevance to European healthcare systems. But that is too easy. EDAC is thought as an international set of methods and the invitation from EDAC is clear: jump on board and join the co-creation of both language and tools towards global innovation from local and contextualised best-practices.
As in the US, healthcare and hospitals all over Europe are challenged by scarcity of resources – the hunt for the best business model is on. We need to activate and cultivate the interrelationships between the built environment and operations. EBD can be our shared tool – combining the best of all different healthcare models – cutting edge and totally sustainable concepts for institutions, buildings and processes that are signified by optimum synergy between the built environment, human activity, equipment, infrastructure and logistics. This would be a great contribution to future health in Europe.
