Evidence-Based Design in Hospital Renovation Projects: A Study of Design Implementation for User Controls.

PURPOSE: The purpose of this article was to investigate and report the implementation of evidence-based design (EBD) principles relating to user controls into hospital renovation projects. BACKGROUND: Progress requires the application of the most recent knowledge and technology. When it comes to the design and construction of healthcare facilities, the latest knowledge comes in the form of EBD research. EBD is the process of basing decisions about the built environment on credible research to achieve the best possible outcomes. The desired outcomes of EBD recommendations include improvements to enhance user control. User control factors include the individual control over bed position, air temperature, lights, sound, and natural light. METHOD: A list of recommendations from existing EBD literature related to user controls was compiled. Construction documents from 30 recent healthcare facility renovation projects across the United States were obtained and analyzed. Implementation levels for the EBD categories of user controls were reported. RESULTS: The findings indicate relatively extensive industry use of EBD principles relating to user control of temperature, lights, and natural lighting. CONCLUSIONS: The findings indicate that EBD recommendations related to user controls are being adopted in practice at consistently high levels. These findings also reveal that there are still areas of potential improvement which could inform those who influence or determine building design, codes, standards, and guidelines. The results are helpful to owners, designers, and contractors by providing a glimpse into how well the industry is recognizing and implementing known best practices. The findings likewise introduce new opportunities for further research which could lead to additional improvement in the healthcare facilities of the future.

From Competition to Collaboration: How a Multi-Firm Research Coalition Is Realizing Rigorous Facility Evaluation at Parkland Hospital.

This case study presents the process of developing a multi-entity Research Coalition to evaluate the new Parkland Hospital. The field of evidence-based design has made progress in systematically investigating relationships between healthcare facility design and a range of human outcomes. Yet healthcare facility evaluation is not typically included in the scope of building contracts. Lack of clear responsibility for evaluation and limited funding have been long-term barriers that the industry has yet to overcome. Firms engaged in design research at Parkland Hospital agreed with hospital representatives to collaborate on an integrated facility evaluation. Each participating entity contributed resources toward the effort. To formalize shared goals and priorities, the group developed a Research Coalition Charter. Goals included streamlining evaluation efforts to minimize burden on the hospital, leveraging multiple expertise areas to vet research aims and approaches, contributing knowledge to inform healthcare design, and innovating a model for multi-firm collaboration. The Coalition also developed guidelines for sharing data and disseminating research findings. To date, the Research Coalition has achieved key milestones including institutional review board exemption, data use and research collaboration agreements, and data collection. The research aims encompass patient and staff outcomes hypothesized to improve in the new facility. Both primary and secondary data are being analyzed to test the hypotheses. Publications of findings are forthcoming. Collaborative research among competitors may be a viable approach to realizing evaluation that is critical to learning for healthcare facility decision makers and design practitioners.

Layout Planning in Healthcare Facilities: A Systematic Review.

This study presents a systematic review of the literature on layout planning in healthcare facilities. The review includes 81 articles from journals, conferences, books, and other documents. Articles were classified in two groups according to their main contents including (i) concepts and guidelines and (ii) techniques and tools to assist in layout planning in healthcare facilities. Results indicate that a great variety of concepts and tools have been used to solve layout problems in healthcare. However, healthcare environments such as hospitals can be complex, limiting the ability to obtain optimal layout solutions. Influential factors may include the flows of patients, staff, materials, and information; layout planning and implementation costs; staff and patients safety and well-being; and environmental contamination, among others. The articles reviewed discussed and often proposed solutions covering one or more factors. Results helped us to propose future research directions on the subject.

Design Lessons From the Analysis of Nurse Journeys in a Hospital Ward.

OBJECTIVE:: The objective is to establish design strategies to help minimize nurse journeys and inform future decision-making. The impact of the ward layout was investigated through a case study ward in a multispecialty hospital in Tehran. BACKGROUND:: Nurse teams have the most direct contact with ward patients. Time spent on activities not part of care provision should be minimized. Literature suggests that a significant part of nurses' time is spent moving between different places within wards, which emphasizes the importance of ward layout. METHODS:: The ethnographic method was adopted for observing nurses' actions based on routes that form a significant share of nurses' daily journeys. Data were collected from 42 nursing staff over 120 hr during different shifts. This provided empirical data on the frequency of each journey which revealed meaningful patterns. Approximately 1,300 room-to-room journeys were made. Conclusions were drawn about the criticality of each route. RESULTS:: There is a significant difference between the frequencies of different routes in the case study ward. The distances between origins and destinations of the most frequently used journeys must remain minimal. Awareness of less frequent routes allows for greater flexibility in ward design. CONCLUSION:: Arrangement of ward spaces can minimize journey times. Healthcare planners and designers can explore the implications of chosen systems on walking distance and, consequently, the nursing staff productivity. For existing wards, rearrangement of space utilization can improve staff productivity. The recommendations can be applied wherever productivity is influenced by walking distances.

Evidence-Based Design and Research-Informed Design: What's the Difference? Conceptual Definitions and Comparative Analysis.

OBJECTIVE: This article provides critical examination and comparison of the conceptual meaning and underlying assumptions of the concepts evidence-based design (EBD) and research-informed design (RID) in order to facilitate practical use and theoretical development. BACKGROUND: In recent years, EBD has experienced broad adoption, yet it has been simultaneously critiqued for rigidity and misapplication. Many practitioners are gravitating to the term RID to describe their method of integrating knowledge into the design process. However, the term RID lacks a clear definition and the blurring of terms has the potential to weaken advances made integrating research into practice. METHOD: Concept analysis methods from Walker and Avant were used to define the concepts for comparison. RESULTS: Conceptual definitions, process descriptions, examples (i.e., model cases), and methods of evaluation are offered for EBD and RID. Although EBD and RID share similarities in meaning, the two terms are distinct. When comparing evidence based (EB) and research informed, EB is a broad base of information types (evidence) that are narrowly applied (based), while the latter references a narrow slice of information (research) that is broadly applied (informed) to create an end product of design. CONCLUSIONS: Much of the confusion between the use of the concepts EBD and RID arises out of differing perspectives between the way practitioners and academics understand the underlying terms. The authors hope this article serves to generate thoughtful dialogue, which is essential to the development of a discipline, and look forward to the contribution of the readership.

Using Evidence-Based Design to Improve Pharmacy Department Efficiency.

Using a case study of a pharmacy department rebuild in the South West of England, this article examines the use of evidence-based design to improve the efficiency and staff well-being with a new design. This article compares three designs, the current design, an anecdotal design, and an evidence-based design, to identify how evidence-based design can improve efficiency and staff well-being by reducing walking time and distance. Data were collected from the existing building and used to measure the efficiency of the department in its current state. These data were then mapped onto an anecdotal design, produced by architects from interviews and workshops with the end users, and an evidence-based design, produced by highlighting functions with high adjacencies. This changed the view on the working processes within the department, shifting away from a focus on the existing robotic dispensing system. Using evidence-based design was found to decrease the walking time and distance for staff by 24%, as opposed to the anecdotal design, which increased these parameters by 9%, and is predicted to save the department 248 min across 2 days in staff time spent walking.

Designing With Empathy: Humanizing Narratives for Inspired Healthcare Experiences.

OBJECTIVE: Designers can and should play a critical role in shaping a holistic healthcare experience by creating empathetic design solutions that foster a culture of care for patients, families, and staff. Using narrative inquiry as a design tool, this case study shares strategies for promoting empathy. BACKGROUND: Designing for patient-centered care infuses empathy into the creative process. Narrative inquiry offers a methodology to think about and create empathetic design that enhances awareness, responsiveness, and accountability. METHODS: This article shares discoveries from a studio on empathetic design within an outpatient cancer care center. The studio engaged students in narrative techniques throughout the design process by incorporating aural, visual, and written storytelling. Benchmarking, observations, and interviews were merged with data drawn from scholarly evidence-based design literature reviews. RESULTS: Using an empathy-focused design process not only motivated students to be more engaged in the project but facilitated the generation of fresh and original ideas. Design solutions were innovative and impactful in supporting the whole person. Similarities as well as differences defined empathetic cancer care across projects and embodied concepts of design empowerment, design for the whole person, and design for healing. CONCLUSIONS: By becoming more conscious of empathy, those who create healthcare environments can better connect holistically to the user to take an experiential approach to design. Explicitly developing a mind-set that raises empathy to the forefront of the design process offers a breakthrough in design thinking that bridges the gap between what might be defined as "good design" and patient-centered care.

Evidence-Based and Value-Based Decision Making About Healthcare Design: An Economic Evaluation of the Safety and Quality Outcomes.

OBJECTIVE: This study describes a vision and framework that can facilitate the implementation of evidence-based design (EBD), scientific knowledge base into the process of the design, construction, and operation of healthcare facilities and clarify the related safety and quality outcomes for the stakeholders. The proposed framework pairs EBD with value-driven decision making and aims to improve communication among stakeholders by providing a common analytical language. BACKGROUND: Recent EBD research indicates that the design and operation of healthcare facilities contribute to an organization's operational success by improving safety, quality, and efficiency. However, because little information is available about the financial returns of evidence-based investments, such investments are readily eliminated during the capital-investment decision-making process. METHOD: To model the proposed framework, we used engineering economy tools to evaluate the return on investments in six successful cases, identified by a literature review, in which facility design and operation interventions resulted in reductions in hospital-acquired infections, patient falls, staff injuries, and patient anxiety. RESULTS: In the evidence-based cases, calculated net present values, internal rates of return, and payback periods indicated that the long-term benefits of interventions substantially outweighed the intervention costs. This article explained a framework to develop a research-based and value-based communication language on specific interventions along the planning, design and construction, operation, and evaluation stages. CONCLUSIONS: Evidence-based and value-based design frameworks can be applied to communicate the life-cycle costs and savings of EBD interventions to stakeholders, thereby contributing to more informed decision makings and the optimization of healthcare infrastructures.

Architecture and health care: a place for sociology.

Sociologists of health and illness have tended to overlook the architecture and buildings used in health care. This contrasts with medical geographers who have yielded a body of work on the significance of places and spaces in the experience of health and illness. A review of sociological studies of the role of the built environment in the performance of medical practice uncovers an important vein of work, worthy of further study. Through the historically situated example of hospital architecture, this article seeks to tease out substantive and methodological issues that can inform a distinctive sociology of healthcare architecture. Contemporary healthcare buildings manifest design models developed for hotels, shopping malls and homes. These design features are congruent with neoliberal forms of subjectivity in which patients are constituted as consumers and responsibilised citizens. We conclude that an adequate sociology of healthcare architecture necessitates an appreciation of both the construction and experience of buildings, exploring the briefs and plans of their designers, and observing their everyday uses. Combining approaches and methods from the sociology of health and illness and science and technology studies offers potential for a novel research agenda that takes healthcare buildings as its substantive focus.

Positive distraction and the rehabilitation hospitals of joão filgueiras lima.

OBJECTIVE: This article discusses the use of positive distraction, an evidence-based design approach, in rehabilitation hospitals in Brazil through the work of João Filgueiras Lima ("Lelé"). BACKGROUND: In many parts of the world architects may not formally incorporate theories of positive distraction and evidence-based design, but there are multiple international examples of health facility architects and designers that use nature, daylighting, art, and social interaction to enhance the healing experience. The work of the Brazilian architect João Filgueiras Lima is a particularly salient example. Lima has been a dominant figure in 20th and 21st century Brazilian architecture and the architect of several rehabilitation facilities. METHODS: First positive distraction is defined as it relates to nature and art, and in the context of rehabilitation hospitals. Second, rehabilitation facilities are defined. The discussion then focuses on awareness of evidence-based design in Latin America. Next, Brazilian healthcare architecture is discussed along with the history of the Brazilian Sarah rehabilitation hospitals designed by Lelé and Lelé's role in the history of Brazilian architecture. Last we look at Lelé's use of positive distraction. RESULTS: Despite Lelé's recognition in Brazil, his work has not gained much international exposure. Lelé played a critical role in the design of the Sarah facilities and served on the board of directors for the Technological Center of the Sarah Network (CTRS) in Brazil from 1992 to 2009. Based on our review of his work it was clear that Lelé used positive distraction as a tool for creating healing environments. CONCLUSIONS: In spite of the lack of formal integration of evidence-based design in healthcare architecture in Latin America, many of its basic tenets have been incorporated in Brazilian rehabilitation hospitals. Lelé's projects are a clear example of this phenomenon and demonstrate an alignment between research and practitioner objectives. The presence of nature, art, and natural light in his rehabilitation hospitals serves as a model for evidence-based design in facilities throughout the world and presents an opportunity to measure the benefits of positive distraction on rehabilitation patient outcomes.

Configuring the hospital in the 21st century

In this policy brief, we will take a fresh look at the hospital, and examine the questions that policy-makers need to be asking about its role in the health care system. Although most health care takes places outside hospitals, for most people, they have come to symbolize the health care system. The capacity of a health care system is often measured by the number of hospitals or hospital beds. Yet these measures tell us almost nothing. A "hospital" may have only a handful of beds, a staff with only basic skills and no infrastructure ­ even no electricity or running water in some parts of the former Soviet Union. Or it may have hundreds of beds, a highly trained staff and sophisticated equipment, operating theatres and laboratories.
