Purpose: The purpose of this study was to explore the relationship between situation awareness (SA) and the physical environment in patient rooms through building a conceptual model.

Background: Nurses work in very complicated and dynamic environments where having high levels of SA could be critical for their performance. Studies have also shown that nurses' awareness of the physical environment and patient room is a part of their awareness of dynamic situations in which nurses' spatial awareness may play a role in SA. Despite literature outlining the importance of SA, there is a lack of studies exploring the relationship between the two.

Method: A literature review was conducted for the study from nursing and psychology databases. Thirty-three articles, books, and dissertations from a scoping review were included for in-depth review.

Results: An in-depth review of the harvested literature indicated that there is in fact a relationship between these two phenomena. Founded on Endsley's model of SA, the literature review in this study offers a conceptual model that articulates a plausible causal pathway between the physical environment and SA.

Conclusions: There are a lot of studies focusing on SA and various aspects of it related to nursing, but almost none mention the physical environment and its impact on SA. The current inquiry suggests that spatial awareness plays a prominent role in SA.

Objective: Translational research to advance design criteria and apply the Childbirth Supporter Study (CSS) findings to practice.

Background: The physical design of birth environments has not undergone substantial improvements in layout or ambiance since the initial move to hospitals. Cooperative, continuously present childbirth supporters are beneficial and are an expectation for most modern birth practices, yet the built environment does not offer support for the supporter.

Methods: To advance design criteria, we use a comparative case study approach to create translational findings. Specifically, CSS findings were used as indicators to advance the Birth Unit Design Spatial Evaluation Tool (BUDSET) design characteristics in pursuit of better support for childbirth supporters in the built hospital birth environment.

Results: This comparative case study provides eight new BUDSET design domain suggestions to benefit the supporter-woman dyad, and subsequently the baby and care providers.

Conclusions: Research-informed design imperatives are needed to guide the inclusion of childbirth supporters as both a supporter and as an individual in the birth space. Increased understanding of relationships between specific design features and childbirth supporters' experiences and reactions are provided. Suggestions to enhance the applicability of the BUDSET for birth unit design facility development are made, specifically ones that will better accommodate childbirth supporters.

Background: Few studies have explored the impact of internal building design features on physical activity. The purpose of this study is to determine building design features associate with physical activity and sedentary behaviors.

Methods: Full-time workers (n = 114) wore an ActivPal monitor for 4 work days to measure physical activity and sedentary behaviors. Participants completed a 25-item survey about the presence of external, internal, and staircase design features at their worksite. Participants also reported their desk type. General linear models were used to examine relations between the number of features present for each category and physical activity (steps per hour) and sedentary behavior (sitting time per hour).

Results: Internal design scores were positively associated with occupational physical activity. Each single item increase in facilitating internal design features was associated with +64.5 steps/hr (p = .045) at work. Workers who reported having a desk job walked 538 fewer steps/hr (p < .01) and sat 17 min more/hr at work than workers who reported not having a desk.

Conclusion: These results suggest that internal design features can promote more movement and less sitting at work. Future studies that examine the longitudinal effect of changing internal design features on occupational physical activity and sedentary behaviors are warranted.

Objectives: To identify how quality and design of streets impacts urban stress.

Background: Few studies have comprehensively addressed environmental factors affecting stress in urban public spaces. However, a remarkable portion of our everyday life is spent in public spaces, particularly streets.

Method: This study seeks to evaluate the effect of three types of streets as major public spaces on stress. These include a street with the dominance of green spaces (A), a motorist-oriented street (B), and a pedestrian street (C). For this purpose, we selected a group of participants (n = 16) aged 20-30, with an equal number of men and women who were generally healthy and had normal stress levels. Participants were asked to wear an electroencephalogram (EEG) headset, walk different streets, and answer the Perceived Restorativeness Scale (PRS) and urban design qualities questionnaires.

Results: According to the results, participants experienced the highest stress in street type B and the lowest in type A.

Conclusions: Green space and vegetation, a sense of security, privacy and coziness, climatic comfort, and safety of space had the most positive effect on stress reduction. Whereas noise pollution, vehicle traffic, and crowdedness were the most critical factors of stress. Finally, our findings suggest that the component of green space has a more significant effect on stress reduction compared with the elimination of vehicle traffic.

Background: Studies show that workspace for the anesthesia providers is prone to interruptions and distractions. Anesthesia providers experience difficulties while performing critical medication tasks such as medication preparation and administration due to poor ergonomics and configurations of workspace, equipment clutter, and limited space which ultimately may impact patient safety, length of surgery, and cost of care delivery. Therefore, improving design of anesthesia workspace for supporting safe and efficient medication practices is paramount.

Objectives: The objective of this study was to develop a set of evidence-based design guidelines focusing on design of anesthesia workspace to support safer anesthesia medication tasks in operating rooms (ORs).

Methods: Data collection was based on literature review, observation, and coding of more than 30 prerecorded videos of outpatient surgical procedures to identify challenges experienced by anesthesia providers while performing medication tasks. Guidelines were then reviewed and validated using short survey.

Results: Findings are summarized into seven evidence-based design guidelines, including (1) locate critical tasks within a primary field of vision, (2) eliminate travel into and through the anesthesia zone (for other staff), (3) identify and demarcate a distinct anesthesia zone with adequate space for the anesthesia provider, (4) optimize the ability to reposition/reconfigure the anesthesia workspace, (5) minimize clutter from equipment, (6) provide adequate and appropriately positioned surfaces for medication preparation and administration, and (7) optimize task and surface lighting.

Conclusion: This study finds many areas for improving design of ORs. Improvements of anesthesia work area will call for contribution and cooperation of entire surgical team.

Background: Many countries and communities in sub-Saharan Africa suffer from inadequate access to healthcare and healthy lifestyles as reflected in their high mortality and morbidity rates. Large-scale interventions like the medical city project presented in this article are necessary to address the significant health burdens faced by populations in this region.

Objectives: This article shows how evidence-based approaches and multisectoral partnerships guided the development of the 327-acre Medical City master plan in Akwa Ibom, Nigeria. This is envisioned to be the first-of-its-kind medical city in this medically underserved "healthcare desert."

Methods: The five-phased, seven-year (2013-2020) master planning process was guided by the overarching design framework of "sustainable one health" along with its 11 objectives and 64 performance measures. The data/evidence used to guide the planning decision-making process came from case studies, literature reviews, stakeholder interviews, and on-site investigations.

Results: The outcome of this project is a comprehensive medical city master plan that includes a self-contained, mixed-use community anchored by a hospital and a primary healthcare village. This medical city provides access to the full range of healthcare services (e.g., curative-to-preventive, traditional-to-alternative) and is supported by multimodal transportation systems and extensive green infrastructure.

Conclusions: This project offers theoretical and practical insights on "designing for health" in a frontier market while responding to the complex local contexts that present many unique challenges and opportunities. Those insights provide useful lessons for researchers and professionals interested in promoting health and healthcare services in healthcare deserts.

Objectives: Serious COVID-19 nosocomial infection has demonstrated a need to design our health services in a different manner. Triggered by the current crisis and the interest in rapid deployable hospital, this article discusses how hospital building layouts can be improved to streamline the patient pathways and thus to reduce the risk of hospital-related infections. Another objective of this work is to explore the possibility to develop flexible and scalable hospital building layouts through modular construction. This enables hospitals to better cope with different future demands and thereby enhance the resilience of the healthcare facilities.

Background: During the first wave of COVID-19, approximate one-seventh to one-fifth COVID-19 patients and majority of infected healthcare workers acquired the disease in NHS hospitals. Similar issues emerged during the Crimean War (1853-1856) when more soldiers died from infectious diseases rather than of battlefield casualties in Scutari Hospital. This led to an important collaborative work between Florence Nightingale, who looked into this problem statistically, and Isambard Kingdom Brunel, who designed the rapid deployment Renkioi Hospital which yielded a death rate 90% lower than that in Scutari Hospital. While contemporary medical research and practice have moved beyond Nightingale's concept of contagion, challenges of optimizing hospital building layouts to support healing and effectively combat nosocomial infections still pose elusive problems that require further investigation.

Methods: Through case study investigations, this article evaluates the risk of nosocomial infections of airborne transmissions under different building layouts, and this provides essential data for infection control in the new-build or refurbished healthcare projects.

Results: Improved hospital layout can be achieved through reconfiguration of rooms and concourse. Design interventions through evidence-based infection risk analysis can reduce congestion and provide extra separation and compartmentalization which will contribute the reduced nosocomial infection rate.

Conclusions: A resilient hospital shall be able to cope with unexpected circumstances and be flexible to change when new challenges arise, without compromising the safety and well-being of frontline medical staff and other patients. Such an organizational resilience depends on not only flexible clinical protocols but also flexible hospital building layouts. The latter allows hospitals to get better prepared for rapidly changing patient expectations, medical advances, and extreme weather events. The reconfigurability of an existing healthcare facility can be further enhanced through modular construction, standardization of building components, and additional space considered.

Objectives: The purpose of this article is to compare three different methods to assess the complexity of a long-term care (LTC) environment for wayfinding before and after an environmental design intervention. The methods include space syntax (SS), the Wayfinding Checklist (WC), and the Tool to Assess Wayfinding Complexity (TAWC).

Background: Wayfinding is important to maintain older adults' independent functioning. The design of environments can impact wayfinding ability by providing support; this can be via building structure or by environmental design features such as signage and landmarks. Few methods or tools have been scientifically validated to assess environments for wayfinding complexity. In order to compare environments in terms of complexity and to measure the impact of interventions, valid and reliable tools are necessary.

Methods: This article discusses the results of the use of three wayfinding design assessment tools using three routes in one LTC environment. The results of the three tools are discussed.

Results: SS analysis could quantitatively measure the complexity of routes using integration values, which indicates connectedness. The TAWC and the WC were able to measure differences in visual field scores pre- and postenvironmental intervention. There were limitations to each tool: the lack of psychometric properties for the TAWC and the WC, and the lack of ability to measure changes in design features within visual fields with SS.

Conclusions: Multiple tools to assess environments for wayfinding design may be needed in studies that test environmental interventions. Future research is needed to provide psychometric testing for the tools.
