Improving wayfinding in hospitals for people with diverse needs and abilities: An exploratory approach based on multi-criteria decision making

Hospital wayfinding systems that are based solely on signage do not provide adequate solutions for wayfinding needs, especially for users with impairments. Moreover, the interaction between user characteristics and the inner space of the building also determines wayfinding efficiency. The aims of this study, therefore, were to identify architectural features that affect spatial orientation and wayfinding behaviors; demonstrate the implementation of a multi-criteria decision-making (MCDM) approach for improving wayfinding in a diverse range of users; and produce a set of quantitative values (i.e., weights) for each selected architectural feature, based on the individual's preferences. Doing so could enable the formulating of practical design guidelines for hospital buildings, tailored to the needs and abilities of the users, to minimize disorientation and confusion - as demonstrated in this paper through a case study. The MCDM approach was chosen as it is based on observations whereby wayfinding resembles a continuous decision-making process, throughout which, users continuously select those architectural features that they perceive as having the greatest wayfinding value.

A comprehensive evaluation model for the intelligent automobile cockpit comfort

Under the background of automobile intelligence, cockpit comfort is receiving increasing attention, and intelligent cockpit comfort evaluation is especially important. To study the intelligent cockpit comfort evaluation model, this paper divides the intelligent cockpit comfort influencing factors into four factors and influencing indices: acoustic environment, optical environment, thermal environment, and human-computer interaction environment. The subjective and objective evaluation methods are used to obtain the subjective weights and objective weights of each index by the analytic hierarchy process and the improved entropy weight method, respectively. On this basis, the weights are combined by using the game theory viewpoint to obtain a comprehensive evaluation model of the intelligent automobile cockpit comfort. Then, the cloud algorithm was used to generate the rank comprehensive cloud model of each index for comparison. The research results found that among the four main factors affecting the intelligent automobile cockpit comfort, human-computer interaction has the greatest impact on it, followed by the thermal environment, acoustic environment, and optical environment. The results of the study can be used in intelligent cockpit design to make intelligent cockpits provide better services for people.

Exploring the Relationship between Window View Quantity, Quality, and Ratings of Care in the Hospital

Hospital ratings reflect patient satisfaction, consumer perception of care, and create the context for quality improvement in healthcare settings. Despite an abundance of studies on the health benefits of the presence and content of window views, there is a gap in research examining how these features may impact patient satisfaction and consumer perceptions of the quality of care received. A quantitative exploratory study collected data from 652 participants regarding their previous stay in the hospital, their perception of windows in their room, and their perception of their room, the hospital, and the quality of care received. On a scale of 0–10, participants with access to windows gave a 1-unit higher rating for the hospital. Access to window views from their bed provided a 1-unit increase, and having a view to green spaces resulted in a 2-unit increase in hospital ratings. Statistically significant results were also found for room ratings and care ratings. Windows in the patient rooms impact the key patient satisfaction measures and patient experience during the hospital stay. Patient room design, bed set up, and quantity and quality of window views may play an important role in shaping the patient’s experience.

Access to Daylight at Home Improves Circadian Alignment, Sleep, and Mental Health in Healthy Adults: A Crossover Study

As the primary environmental cue for the body’s master biological clock, light–dark patterns are key for circadian alignment and are ultimately fundamental to multiple dimensions of health including sleep and mental health. Although daylight provides the proper qualities of light for promoting circadian alignment, our modern indoor lifestyles offer fewer opportunities for adequate daylight exposure. This field study explores how increasing circadian-effective light in residences affects circadian phase, sleep, vitality, and mental health. In this crossover study, 20 residents spent one week in their apartments with electrochromic glass windows and another week with functionally standard windows with blinds. Calibrated light sensors revealed higher daytime circadian-effective light levels with the electrochromic glass windows, and participants exhibited consistent melatonin onset, a 22-min earlier sleep onset, and higher sleep regularity. In the blinds condition, participants exhibited a 15-min delay in dim light melatonin onset, a delay in subjective vitality throughout the day, and an overall lower positive affect. This study demonstrates the impact of daytime lighting on the physiological, behavioral, and subjective measures of circadian health in a real-world environment and stresses the importance of designing buildings that optimize daylight for human health and wellbeing.

Assessing the Supportiveness of Healthcare Environments' Light and Color: Development and Validation of the Light and Color Questionnaire (LCQ)

Aim:

The aim of this study was to develop and evaluate a self-report instrument measuring patients’, family members’, and staff’s perceived support from light and color in the physical environment of an emergency department (ED)—the Light and Color Questionnaire (LCQ).

Background:

The physical care environment is an important part of a comprehensive caring approach in all levels of care not only for patients but also for family members and staff. However, no existing self-report questionnaire assessing the extent to which light and color are perceived as being supportive in the physical care environment from the users’ perspective was found.

Method:

The LCQ was developed as part of a pre–post study in which an ED serving 125,000 people was refurbished and remodeled using evidence-based design. The LCQ consists of six items for light and five items for color and assesses awareness/orientation, safety/security, functional abilities, privacy, personal control, and stimulation. The study was carried out in four steps: constructions of items, assessment of face validity, data collection, and data analysis.

Result/Conclusion:

Psychometric evaluation of the two versions, LCQ-Patient/Family member and LCQ-Staff, showed satisfactory content and internal validity (>90%) and high internal consistency (Cronbach’s coefficient α = .9) to support the use of the questionnaire for research and development purposes. Explorative factor analysis of a total of 600 questionnaire responses confirmed light and color as distinctive and independent dimensions creating perceptions of more or less supportiveness for respondents. The LCQ instrument may be useful for architects, administrators, and researchers of healthcare environments.

The Influence of Visibility on Medical Teamwork in Emergency Departments: A Mixed-Methods Study

AIM

This mixed-methods study delivers empirical evidence on the influence of visibility on healthcare teamwork in Emergency Departments (EDs). This study researchers hypothesized that with changes of visibility in EDs, teamwork among medical staff members will be impacted.

BACKGROUND

Prior research results suggest that visibility can influence health-setting efficacy. Teamwork is one of the components of each healthcare system that can be supported by environmental design.

METHOD

Visibility in four subject sites from the same healthcare system was objectively measured by morphology plan analyses. Teamwork among medical staff members was the behavioral variable of interest and explored through field observations, interviews, and surveys.

RESULTS

The qualitative outcomes demonstrated that teamwork can be enhanced by improved visibility, while the quantitative findings supported the idea that some specific measures of visibility were correlated with teamwork.

CONCLUSION

This study provides a model for future research on the association between healthcare staff behavior and ED plan configuration. The enhancement of ED design, considering the significance of visibility, enhances the perceptions of nurses and physicians in terms of teamwork.

The Perceptions of Nurses About the Behavioral Needs for Daylighting and View to the Outside in Inpatient Facilities

Objectives:

This research aims to explore the perceptions of nursing staff regarding the effects of daylighting on behavioral factors including mood, stress, satisfaction, medical error, and efficiency.

Background:

In spite of an extensive body of literature seeking to investigate the impact of daylighting on patients, a limited number of studies have been done for the sake of nurses’ perceptions and behavioral responses.

Method:

A mixed-methods approach, comprised of qualitative explorations (structured interviews) and a validated survey, was applied and the results were compared and triangulated. Five nurses were interviewed and 156 nurses volunteered for a lighting survey from six departments of three inpatient facilities in Iran.

Results:

The findings of this study are consistent with the existing evidence that daylighting and view to the outside enhance nurses’ perceptions regarding satisfaction, mood, stress, medical error, and alertness, while reducing fatigue and stress.

Conclusion:

Patient rooms and work stations are the most crucial areas to provide daylighting from nurses’ perspectives.

The Role of Environmental Design in Cancer Prevention, Diagnosis, Treatment, and Survivorship: A Systematic Literature Review

The purpose of this literature review is to provide a better understanding of the impact that environmental design can have on the process of cancer prevention, diagnosis, treatment, and survivorship. Cancer is considered a chronic disease in the United States, and more than 1.6 million new cases are diagnosed annually. New strategies of cancer care propose patient-centered services to achieve the best outcome, and researchers have found that environmental design can be an important part of improving this care. Searches were conducted in the PubMed and Google Scholar databases as well as in specific healthcare design journals such as Health Environments Research & Design, Environmental Psychology, and Environment and Behavior. The criteria for articles included in the review were (a) English-language articles related to facility design, which addressed (b) the topics of built environment in relation to cancer diagnosis, treatment, and survivorship, and were (c) published in peer-reviewed journals between 2000 and 2017. Finally, 10 articles were selected, and the contents were analyzed. The selected articles demonstrate that environmental design is one of the critical factors for success throughout the whole continuum of cancer care from diagnosis to end-of-treatment. Some of the specific conclusions from the review are that "neighborhood-oriented" design strategies can be beneficial (by providing accessibility to all facilities along the patient's path), that access to nature for patients, staff, and visitors alike is associated with better outcomes, and that provisions for natural lighting and noise reduction are associated with cancer patients' well-being.

The Impact of Visibility on Teamwork, Collaborative Communication, and Security in Emergency Departments: An Exploratory Study

The aim of this study was to examine the influence of visibility on teamwork, collaborative communication, and security issues in emergency departments (EDs). This research explored whether with high visibility in EDs, teamwork and collaborative communication can be improved while the security issues will be reduced. Visibility has been regarded as a critical design consideration and can be directly and considerably impacted by ED's physical design. Teamwork is one of the major related operational outcomes of visibility and involves nurses, support staff, and physicians. The collaborative communication in an ED is another important factor in the process of care delivery and affects efficiency and safety. Furthermore, security is a behavioral factor in ED designs, which includes all types of safety including staff safety, patient safety, and the safety of visitors and family members. This qualitative study investigated the impact of visibility on teamwork, collaborative communication, and security issues in the ED. One-on-one interviews and on-site observation sessions were conducted in a community hospital. Corresponding data analysis was implemented by using computer plan analysis, observation and interview content, and theme analyses. The findings of this exploratory study provided a framework to identify visibility as an influential factor in ED design. High levels of visibility impact productivity and efficiency of teamwork and communication and improve the chance of lowering security issues. The findings of this study also contribute to the general body of knowledge about the effect of physical design on teamwork, collaborative communication, and security.

The Impact of Environmental Design on Teamwork and Communication in Healthcare Facilities: A Systematic Literature Review

The purpose of this systematic review is to investigate the current knowledge about the impact of healthcare facility design on teamwork and communication by exploring the relevant literature. Teamwork and communication are behavioral factors that are impacted by physical design. However, the effects of environmental factors on teamwork and communication have not been investigated extensively in healthcare design literature. There are no published systematic reviews on the current topic. Searches were conducted in PubMed and Google Scholar databases in addition to targeted design journals including Health Environmental Research & Design, Environment and Behavior, Environmental Psychology, and Applied Ergonomics. Inclusion criteria were (a) full-text English language articles related to teamwork and communication and (b) involving any healthcare built environment and space design published in peer-reviewed journals between 1984 and 2017. Studies were extracted using defined inclusion and exclusion criteria. In the first phase, 26 of the 195 articles most relevant to teamwork and 19 studies of the 147 were identified and reviewed to understand the impact of communication in healthcare facilities. The literature regarding the impact of built environment on teamwork and communication were reviewed and explored in detail. Eighteen studies were selected and succinctly summarized as the final product of this review. Environmental design, which involves nurses, support staff, and physicians, is one of the critical factors that promotes the efficiency of teamwork and collaborative communication. Layout design, visibility, and accessibility levels are the most cited aspects of design which can affect the level of communication and teamwork in healthcare facilities.
