The impact of windows and daylight on acute-care nurses' physiological, psychological, and behavioral health

Fatigue in nurses and medication administration errors: A scoping review

BACKGROUND

Medication administration errors (MAEs) cause preventable patient harm and cost billions of dollars from already-strained healthcare budgets. An emerging factor contributing to these errors is nurse fatigue. Given medication administration is the most frequent clinical task nurses undertake; it is vital to understand how fatigue impacts MAEs.

OBJECTIVE

Examine the evidence on the effect of fatigue on MAEs and near misses by registered nurses working in hospital settings.

METHOD

Arksey and O'Malley's scoping review framework was used to guide this review and PAGER framework for data extraction and analysis. The PRISMA checklist was completed. Four electronic databases were searched: CINAHL, PubMed, Scopus and PsycINFO. Eligibility criteria included primary peer review papers published in English Language with no date/time limiters applied. The search was completed in August 2021 and focussed on articles that included: (a) registered nurses in hospital settings, (b) MAEs, (c) measures of sleep, hours of work, or fatigue.

RESULTS

Thirty-eight studies were included in the review. 82% of the studies identified fatigue to be a contributing factor in MAEs and near misses (NMs). Fatigue is associated with reduced cognitive performance and lack of attention and vigilance. It is associated with poor nursing performance and decreased patient safety. Components of shift work, such as disruption to the circadian rhythm and overtime work, were identified as contributing factors. However, there was marked heterogeneity in strategies for measuring fatigue within the included studies.

RELEVANCE TO CLINICAL PRACTICE

Fatigue is a multidimensional concept that has the capacity to impact nurses' performance when engaged in medication administration. Nurses are susceptible to fatigue due to work characteristics such as nightwork, overtime and the requirement to perform cognitively demanding tasks. The mixed results found within this review indicate that larger scale studies are needed with particular emphasis on the impact of overtime work. Policy around safe working hours need to be re-evaluated and fatigue management systems put in place to ensure delivery of safe and quality patient care.

Daily rhythms, light exposure and social jetlag correlate with demographic characteristics and health in a nationally representative survey

The timing of daily activity in humans have been associated with various demographic and health-related factors, but the possibly complex patterns of confounding and interaction between these has not been systematically explored. We use data from Hungarostudy 2021, a nationally representative survey of 7000 Hungarian adults to assess the relationship between self-reported chronotype, social jetlag (using the Munich Chronotype Questionnaire), demographic variables and self-reported health and demographic variables, including ethnic minority membership. Supporting the validity of self-reports, participants with later chronotypes reported the lowest daytime sleepiness at a later clock time. We found that older age, female sex, a more eastward and southward geographical position, residence in a smaller settlement, less education and income, religiousness and cohabiting with small children were associated with an earlier chronotype. Younger age, higher education and income, and cohabiting with small children were associated with increased social jetlag. Of the 48 health-related variables surveyed, the relationship with both chronotype and social jetlag were mostly accounted for by age, sex, and socioeconomic effects, but we identified alcohol consumption, smoking, and physical activity as predictors of both social jetlag and chronotype, while a number of disorders were either positively or negatively associated with chronotype and social jetlag. Our findings from a large, nationally representative sample indicate that both biological and social factors influence chronotype and identified both demographic and health-related variables as risk factors for social jetlag. Our results, however, do not support a causal relationship between light exposure and mental health.

Coping and Caregiving: Leveraging Environmental Design to Moderate Stress Among Healthcare Workers in the Emergency Department Setting

BACKGROUND

Due to exposure to overwhelming work stressors, approximately half of emergency department (ED) physicians and nurses experience burnout, leading to lower productivity, lower quality of care, higher risk of medical errors, higher rates of absenteeism, and eventually turnover. Growing evidence suggests that the physical environment can be leveraged to support healthcare workers' well-being.

OBJECTIVES

This study aimed to identify (1) self-care behaviors that healthcare workers engage in to help them cope with job-related stress, (2) where they engage in those behaviors, (3) attributes of the built environment that may support coping behaviors.

METHODS

A mixed-methods study was conducted in three EDs, using online questionnaires (n = 85) and interviews (n = 20).

RESULTS

Job-related stress was derived from interruptions, workload and inability to take breaks, insufficient workspace, lack of privacy, unpredictability of EDs, and security concerns. Talking with a colleague, getting something to eat or drink, listening to music, and taking a walk were considered destressing activities. The bathroom was considered a place for destressing by the majority of participants, followed by outside areas, physician-only areas, and care team stations. Supportive environmental features included sufficient workspace, maximized privacy, reduced noise and clutter, controlled temperature and lighting, spaces for decompressing, spaces for documentation, close-by breakrooms with enough eating space and massage chairs, chairs with back support, standing desks, food options, and convenient bathrooms.

CONCLUSIONS

Design decisions play an important role in supporting stress reduction among healthcare workers. This study provides several strategies to achieve this aim.

Fiat Lux: Light and Pedagogy for the 21st Century

Background

The relationship between the quality of the learning environment and student outcomes is receiving more serious attention from educational psychologists, neurologists, ophthalmologists, orthopedists, surgeons, oncologists, architects, ergonomists, nutritionists, and Michelin star chefs. There is a role for ergonomic office and school design to positively impact worker and student productivity, and one design attribute drawing attention is the indoor lit environment. In this review, we expand upon the role that light plays in education, as it has enabled millions of pupils to read at late hours, which were previously too dark. However, still unappreciated is the biological effects of artificial light on circadian rhythm and its subsequent impacts on health and learning outcomes.

Summary

This review describes the current state of light in the educational environment, its impact, and the effect of certain inexpensive and easy-to-implement adaptations to better support student growth, learning and development. We find that the current lighting environment for pupils is sub-optima based on biological mechanism and may be improved through cost effective interventions. These interventions can achieve greater biological harmonization and improve learner outcomes.

Key Message

The impact of the lighting environment in educational institutions on pupil biology has received minimal attention thus far. The current lighting environment in schools is not conducive to student health and educational performance. Cost-effective approaches can have an outsized impact on student health and educational attainment. We strongly recommend educational institutions take the lit environment into account when designing educational programs.

Evidence-Based Design in the Hospital Environment: A Staff's Burnout Study in the COVID-19 Era

OBJECTIVE

This study aimed to evaluate the evidence-based design of the hospital physical space effect on the burnout of nurses and physicians during COVID-19. The research question was to identify the connection between daylight, nature-view windows, and hospital staff burnout during Covid-19.

BACKGROUND

The evidence-based design in the hospital environment affects the health of the medical staff. The promotion of the hospital environment has a significant effect on healthcare system improvement.

METHODS

This cross-sectional study was performed on 406 nurses and physician's burnout in Guilan province in 2020. Three questionnaires were used: demographic, physical space of the hospital, daylight, nature-view windows, and Maslach Burnout Inventory. Logistic regression (LR) analysis was used to determine the association between burnout and the hospital environment. The significance level was considered with p < .05.

RESULTS

The results showed statistically significant correlations between patient units and the environmental characteristics of the hospitals with staff's burnout (p < .001). Of note, 62.9% of physicians and 71.9% of nurses had moderate work-related burnout. The highest burnout score was seen among staffs of emergency departments adjusted multivariate LR model revealed that 27.1% of work-related burnout in nurses and physicians was predictable with age, light, marital status, and hospitals. Our results showed that accessing more daylight could reduce burnout (p = .018, odds ratio [OR] = 0.910).

CONCLUSION

Based on the result, the daylight impact on burnout reduction is more significant than other factors. It is suggested that adequate lighting, proper environmental design, and nature-view windows could create appropriate space for enhancing medical staff satisfaction and reducing burnout.

Evaluating Therapeutic Healthcare Environmental Criteria: Architectural Designers' Perspectives

This study presents architectural designers’ perception of the importance of healthcare environmental criteria in the implementation of user-centered, therapeutic hospital design. Architectural designers with over three years of professional experience (N = 182) in South Korea were surveyed using an empirical questionnaire. The extensive interviews of 15 hospital design experts followed to interpret the survey results and discuss the barriers and suggestions for the successful delivery of therapeutic healthcare design practice. Among the 27 variables selected from the preliminary literature review, factor analyses revealed seven important therapeutic environmental criteria (i.e., management, interior design, spatial quality, service, nature and rest, ambient indoor comfort, and social program and space; χ2 = 1783.088, df = 300, p < 0.001). Analyses of variance revealed the level of importance among these criteria related to respondents’ personal and professional characteristics. Significant differences were found for the variables from the management, interior design, and spatial quality factors in relation to the respondents sex and age. For the successful delivery of therapeutic healthcare design, the design experts highlighted the implementation of evidence-based design practice that integrates local and international knowledge from various hospital users and multi-disciplinary specialists participating in the healthcare design process.

Study on value-based design of healthcare facilities: Based on review of the literature in the USA and Japan

With limited medical resources, it is of great significance for countries all over the world to explore architectural design methods to enhance the value of medical facilities. Therefore, it is very necessary to carry out an extensive international comparison. In order to grasp the research trend of healthcare facilities in the world, this paper conducts co-occurrence analysis, cluster analysis, and trend analysis of the keywords of 334 English articles and 153 Japanese articles related to healthcare facilities published in important academic journals in the USA and Japan in the past 15 years. We not only compare the similarities and differences in healthcare facility research between the USA and Japan, but also explore the reasons for these differences. It is found that by introducing three kinds of value variables, such as time, space, and behavior, we can not only well explain the difference in the solution of healthcare facilities in the USA and Japan to reduce medical costs but also provide new ideas for architectural design to enhance the value of hospitals. Based on the above analysis, a conceptual framework of value-based design of healthcare facilities that combines the advantages of the USA and Japan is proposed in this paper.

The Mediating Effect of Fatigue on the Nature Element, Organisational Culture and Task Performance in Central Taiwan

In the current dynamic business environment, managing the physical working environment of the workforce has become an important part of the company. This study seeks to investigate the effects of the nature element and organisational culture on the task performance of employees with fatigue as a mediator, based on a sample of 103 white-collar employees who work in the central district of Taichung City during the spring and using a purposive sampling method. The data were collected through a self-administered subjective measurement instrument questionnaire and were analysed using Structural Equation Modelling (SEM) path analysis. The results show that organisational culture and task performance were significantly positive. The mediating effect of fatigue caused this relationship to become negative. It was also found that there was a negative relationship between nature elements and task performance. The results provide insights into the importance of employers in providing a healthy workplace which promotes collaboration, health, safety, and the wellbeing of the employee in line with the recommendations of the World Health Organisation (WHO). The study concludes that future international comparative studies can be performed to identify the best workplace design that can reduce employees’ fatigue and alleviate their current work performance.

Understanding "Work as Done": Using a Structured Video-Based Observational Method to Understand and Model the Role of the Physical Environment in Complex Clinical Work Systems

OBJECTIVE

To describe the planning, development, and implementation of a structured video-based observational method that can be used to systematically examine and model the role of the physical environment within healthcare systems.

BACKGROUND

Direct observation methods are often used in healthcare to study complex healthcare systems. However, these observations often occur in real time, which predisposes the collected data to shortcomings such as time lags in recording of activities, overlooking events, or limiting the scope of information than can be collected. Video observation approaches eliminate many of these challenges and provide opportunities for researchers to understand and model the role of the physical environment.

METHODS

An approach to developing and implementing a structured video-based observational method to study and model complex health systems is presented.

RESULTS

A structured observational approach can be highly effective for collecting multiple layers of data necessary for understanding interactions between the physical environment and other systems components in healthcare settings. The proposed video-based observation method is effective in settings that have clearly defined environmental boundaries, limited number of people, are complex and fast-paced such as the OR, ED trauma rooms, and ICU rooms.

CONCLUSIONS

Video-based observation is an effective complement to the traditional observational method for in-depth study of the built environment in health systems, enabling researchers to employ quantitative approaches to data collection and analysis, in addition to qualitative interpretations.

Mapping Healthcare Spaces: A Systematic Scoping Review of Spatial and Behavioral Observation Methods

OBJECTIVE

To provide a taxonomy of spatial observation methods that are commonly used in healthcare environments research and to describe their relative success.

BACKGROUND

Spatial observation is a valuable but resource intensive research method that is often used in healthcare environments research, but which frequently fails to deliver conclusive results. There is no existing catalog of the different spatial and behavioral observation methods that are used in healthcare design research and their benefits or limitations.

METHODS

The review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Ten key databases were searched, and articles were screened by both authors.

RESULTS

Across 67 included studies, 79 observation methods were reported. We categorized those into four, distinct methodological approaches, outlining the benefits, limitations, and suitability of each for obtaining different types of results. Common limitations included difficulty generalizing to other contexts and a lack of detailed description during data collection which led to key environment variables not being recorded. More concrete conclusions were drawn when observation methods were combined with complimentary methods such as interview.

CONCLUSIONS

The relative success of spatial observation studies is dependent on the fit of the method selected relative to the research question, approach, and healthcare setting; any complimentary methods delivered alongside it; and the analysis model employed. This article provides researchers with practical advice to guide the appropriate selection of spatial observation methods.

Assessing Preferences and Perceived Restorative Qualities of Break Spaces for Nurses in China

OBJECTIVE

This study investigated Chinese nurses' preferences for (a) proximity of break areas, (b) functionality of break areas, (c) amenities, and (d) nature-related environmental features.

BACKGROUND

While nurses in China need support to adequately perform their jobs, little is known about how restorative spaces impact their mental and physical health.

METHODS

Data were collected through interviews (N = 12), survey questionnaires (N = 88), and visual assessments (N = 88) from nurses who worked in inpatient settings in China.

RESULTS

Nurses preferred the break room to be close to nursing stations; to have visual privacy from patients; and to provide space and facilities for drinking, taking naps, dining, and chatting with colleagues. Balconies and windows were shown to have a significant restorative effect. Well-designed break areas were perceived to have positive impacts on nurse perceived levels of well-being and increase nurses' satisfaction levels with their work environment.

CONCLUSION

The study outcomes emphasize the importance of restorative spaces for inpatient nurses and recommend including natural elements in the break rooms.

A Study of Workspace Design Characteristics Exemplified by Nurses' Satisfaction Within Three Intensive Care Units in a University Hospital

BACKGROUND

The critical conditions of intensive care patients require providing them with a higher acuity of care. Thus, it is essential to focus on critical care nurses and improve their work environment in a way that maximizes productivity, collaboration, satisfaction, and leads to improved patient care.

PURPOSE

This study aims to explore the role the workplace layout design play in determining nurses' satisfaction in three intensive care units (ICUs) at a university hospital.

METHOD

A prospective, cross-sectional, single-center, survey-based design was employed in this study. Data were obtained, via a standardized questionnaire, from 36 morning shift nurses. The nurses' self-reported satisfaction scores in three different ICUs with differing overall layouts, nursing station locations, and workplace design were statistically compared.

RESULTS

The study found that ICU 1 (private rooms, single corridor, central nursing station, close to supported services) had higher nursing satisfaction levels than ICUs 2 and 3 (open wards with separate service zones), F _(2,34) = 5.054, p = .012. However, overall satisfaction was higher with the ICU 2 primary workspace design, possibly due to the perceived acoustic privacy in this configuration, F _(2,34)= 4.492, p = .019. The ability of the ICU layout design to enhance teamwork and minimize traffic in patients care areas was found to be an important predictor of nurses' satisfaction. The primary workspace design capacity to minimize congestion and the presence of large numbers of providers in a confined workplace might account for variation in nurses' satisfaction.

CONCLUSION

Physical environment variables in the ICU design may contribute to staff workplace satisfaction scores and may help in guiding informed choices regarding the future ICU design.

Operating room nurses' experiences of limited access to daylight in the workplace - a qualitative interview study

Background

The operating room nurse is, among other things, responsible for patient safety and maintaining an aseptic environment. For hygienic reasons unnecessary traffic in the operating room should be avoided, which may mean that the operating room nurse works long shifts without relief. Operating departments are usually separated, where there might be no daylight opportunities in the operating room. The purpose of the study was to describe operating room nurses’ experiences of limited access to daylight in the workplace.

Method

Qualitative design with four semi-structured focus groups of totally 15 operating room nurses. The analysis was performed with a content analysis with an inductive approach.

Results

The study generated two main categories, difference in light and contact with the outer world. Operating room nurses felt that daylight affected them differently from the light from lamps, where daylight was considered important for experiencing well-being. Daylight could lead to a sensation of joy but also increased awareness and energy which seemed to improve the ability to perform at work. The limited access to daylight contributed to fatigue and led to an internal stress that affected the nurses even after work. Having opportunities to look out through windows under a workday was important to experience contact with the outside world and created a sense of time.

Conclusion

To look out can reduce the feeling of being trapped in the closed context that the operating department entails. It can also lead to increased well-being and comfort in the workplace. We consider that daylight is an important component in the physical work environment that needs to be taken into consideration in further research as well as in new construction of operations departments.

"Shedding Light on Light": A Review on the Effects on Mental Health of Exposure to Optical Radiation

In relation to human health and functioning, light, or more specifically optical radiation, plays many roles, beyond allowing vision. These may be summarized as: regulation of circadian rhythms; consequences of direct exposure to the skin; and more indirect effects on well-being and functioning, also related to lifestyle and contact with natural and urban environments. Impact on mental health is relevant for any of these specifications and supports a clinical use of this knowledge for the treatment of psychiatric conditions, such as depression or anxiety, somatic symptom disorder, and others, with reference to light therapy in particular. The scope of this narrative review is to provide a summary of recent findings and evidence on the regulating functions of light on human beings’ biology, with a specific focus on mental health, its prevention and care.

In the Moment: Fostering Mindfulness and Reducing Stressors in the Healthcare Workplace

While healthcare design research has primarily focused on patient outcomes, there is a growing recognition that environmental interventions could do more by promoting the overall quality of care, and this requires expanding the focus to the health and well-being of those who deliver care to patients. Healthcare professionals are under high levels of stress, leading to burnout, job dissatisfaction, and poor patient care. Among other tools, mindfulness is recommended as a way of decreasing stress and helping workers function at higher levels. This article aims to identify potential environmental strategies for reducing work-related stressors and facilitating mindfulness in healthcare settings. By examining existing evidence on workplace mindfulness and stress-reducing design strategies, we highlight the power of the physical environment in not only alleviating stressful conditions but intentionally encouraging a mindful perspective. Strategies like minimizing distractions or avoiding overstimulation in the healthcare environment can be more effective if implemented along with the provision of designated spaces for mindfulness-based programs. Future research may explore optimal methods and hospital workers' preferences for environments that support mindfulness and stress management. The long-term goal of all these efforts is to enhance healthcare professionals' well-being, reignite their professional enthusiasm, and help them be resilient in times of stress.

Study of the Physical Environment of Waiting Areas and Its Effects on Patient Satisfaction, Experience, Perceived Waiting Time, and Behavior in China

OBJECTIVES

This study examines the physical environment in the outpatient waiting area and its effects on overall satisfaction, experience, perceived waiting time, and behavior.

BACKGROUND

Waiting can be a frustrating experience for patients. Previous studies on waiting areas in hospitals have been rooted mainly in the Western cultural context, and research focusing on the impact of the physical environment on the waiting experience with the denser patient concentration in China is important.

METHODS

Physical environment measurements, observations, and questionnaire surveys were employed.

RESULTS

The actual lighting intensity and sound level did not meet the national standards. Sound level and satisfaction with the size of the waiting area, signage system, and visual art on the wall were significant predictors (R ² = .463, p = .000) for overall satisfaction. Experiences related to the size of the waiting area, seating, signage system, and restrooms were significant predictors (R ² = .373, p = .000) of overall waiting experience. The experience related to the acoustic environment (β = -.184, p = .006) had a significant relationship with perceived waiting time. The increase in participants' behaviors of looking out of a window and the decrease in looking at other people, looking around, dozing, and looking at a wall might result from a substantial increase in lighting and the availability of a nature view from the window.

CONCLUSIONS

The effect of the physical setting of waiting areas may positively impact patient satisfaction, waiting experience, perceived waiting time, and behavior, which has implications for patient-centered design.

Intense Light-Mediated Circadian Cardioprotection via Transcriptional Reprogramming of the Endothelium

Consistent daylight oscillations and abundant oxygen availability are fundamental to human health. Here, we investigate the intersection between light-sensing (Period 2 [PER2]) and oxygen-sensing (hypoxia-inducible factor [HIF1A]) pathways in cellular adaptation to myocardial ischemia. We demonstrate that intense light is cardioprotective via circadian PER2 amplitude enhancement, mimicking hypoxia-elicited adenosine- and HIF1A-metabolic adaptation to myocardial ischemia under normoxic conditions. Whole-genome array from intense light-exposed wild-type or Per2^-/- mice and myocardial ischemia in endothelial-specific PER2-deficient mice uncover a critical role for intense light in maintaining endothelial barrier function via light-enhanced HIF1A transcription. A proteomics screen in human endothelia reveals a dominant role for PER2 in metabolic reprogramming to hypoxia via mitochondrial translocation, tricarboxylic acid (TCA) cycle enzyme activity regulation, and HIF1A transcriptional adaption to hypoxia. Translational investigation of intense light in human subjects identifies similar PER2 mechanisms, implicating the use of intense light for the treatment of cardiovascular disease.

Lighting Control in Patient Rooms: Understanding Nurses' Perceptions of Hospital Lighting Using Qualitative Methods

PURPOSE

This study differs in its methodological approach from previously published research by interpreting qualitative results against existing literature to understand how nurses conceptualize medical-surgical patient rooms as productive settings in relation to lighting, as well as the ways in which nurses believe these spaces could be enhanced for patient satisfaction.

METHODS

Content analysis was used to interpret themes emerging from nurses' subjective responses to open-ended items. Three of the facilities had older, traditional lighting systems; one had a contemporary framework.

RESULTS

A theme of environmental control over both overhead and task lighting emerged from data from all items. Although controllability was among the "best" lighting attributes, more refinement is necessary for optimal staff productivity and patient satisfaction. Daylighting was also considered to be among the best attributes. Control over light level via additional dimming capability for patients, as well as additional light sources, was prominent across the four hospitals. Unique to the more modern facility, trespassing of light was problematic for nurses considering the experiences of patients-even where modern models exist, more attention can be paid to the ways in which window shades, and light sources outside of rooms, penetrate spaces and affect users.

CONCLUSION

The finding that nurses and patients desire greater control over the lighting in patient rooms is consistent with Ulrich's theory of supportive design for healthcare and coincides with advances in lighting technology. Despite differences in the level of sophistication in lighting among the four facilities, control continues to be a primary concern for nurses.

The intensive care unit environment from the perspective of medical, allied health and nursing clinicians: A qualitative study to inform design of the 'ideal' bedspace

BACKGROUND

While the impact of the intensive care environment on patients' experiences and outcomes has been extensively studied, relatively little research has examined the impact on clinicians and their provision of care in the intensive care unit (ICU). Understanding staff experience and views about the environment is needed to optimise the ICU environment, patient outcomes and staff wellbeing.

OBJECTIVE

The objective of this study was to inform design of an optimised intensive care bedspace by describing clinicians' views about the current environment, including experience, impact on performance of clinical duties, and experience and outcomes of patients and family members.

METHODS

A pragmatic, qualitative descriptive study was conducted, with data collected in focus groups and interviews with 30 intensive care clinicians at a large cardiothoracic specialist hospital and analysed using the framework approach.

RESULTS

Participants acknowledged that the busy and noisy ICU provided a suboptimal healing environment for patients, was confronting for visiting families and exposed clinicians to risk of psychological injury. The bedspace, described as small and cluttered, hindered provision of clinical care of various kinds and contributed to an increased risk of staff physical injuries. Participants noted that the bland, sterile environment, devoid of natural light and views of the outside world, negatively affected both staff and patients' mood and motivation. Aware of the potential benefits of natural light, cognitive stimulation and visually appealing environments for patients and families, clinicians were frustrated by their inability to personalise the bedspace. Some participants, while acknowledging the importance of family contact for patients, were concerned about the impact of visitors on care delivery, particularly within already crowded bedspaces, suggesting restrictions on visiting.

CONCLUSIONS

Intensive care clinicians perceive that the current intensive care environment is suboptimal for patients, their families and staff and may contribute to suboptimal patient outcomes. The intensive care bedspaces need to be redesigned to ensure they are built around the needs of the people using them. Optimisation is dependent on engaging all stakeholders in future design processes.

Healthy Behaviors through Behavioral Design-Obesity Prevention

Evidence for behavior modification for improved health outcomes was evaluated for nutrition, physical activity (PA), and indoor environmental quality (IEQ). The databases searched included LISTA, PubMed, and Web of Science, with articles rated using an a priori baseline score of 70/100 to establish inclusion. The initial search produced 52,847 articles, 63 of which were included in the qualitative synthesis. Thirteen articles met inclusion for nutrition: cafeteria interventions, single interventions, and vending interventions. Seventeen articles on physical activity were included: stair use, walking, and adjustable desks. For IEQ, 33 articles met inclusion: circadian disruption, view and natural light, and artificial light. A narrative synthesis was used to find meaningful connections across interventions with evidence contributing to health improvements. Commonalities throughout the nutrition studies included choice architecture, increasing the availability of healthy food items, and point-of-purchase food labeling. Interventions that promoted PA included stair use, sit/stand furniture, workplace exercise facilities and walking. Exposure to natural light and views of natural elements were found to increase PA and improve sleep quality. Overexposure to artificial light may cause circadian disruption, suppressing melatonin and increasing risks of cancers. Overall, design that encourages healthy behaviors may lower risks associated with chronic disease.

Effects of biophilic interventions in office on stress reaction and cognitive function: A randomized crossover study in virtual reality

Biophilia hypothesis suggests humans have an innate connection to nature which may affect our health and productivity. Yet we currently live in a world that is rapidly urbanizing with people spending most of their time indoors. We designed a randomized crossover study to let 30 participants experience three versions of biophilic design in simulated open and enclosed office spaces in virtual reality (VR). Throughout the VR session, we measured blood pressure, heart rate, heart rate variability, and skin conductance level and administered cognitive tests to measure their reaction time and creativity. Compared to the base case, participants in three spaces with biophilic elements had consistently lower level of physiological stress indicators and higher creativity scores. In addition, we captured the variation in the intensity of virtual exposure to biophilic elements by using eye-tracking technology. These results suggest that biophilic interventions could help reduce stress and improve creativity. Moreover, those effects are related to both the types of biophilic elements and may be different based on the workspace type (open vs enclosed). This research demonstrates that VR-simulated office spaces are useful in differentiating responses to two configurations and among biophilic elements.

Understanding the impact of the physical health care environment on nurse fatigue

AIM(S)

The purpose of this study was to investigate factors in the physical health care environment (PHE) contributing to nurse fatigue.

BACKGROUND

Nurses experience high levels of physical, mental and overall fatigue related to the physically demanding and mentally complex nature of bedside care.

METHOD(S)

This study used secondary data analysis of a 2017 focus group session, which explored: (a) challenges nursing professionals face while delivering care, (b) the effect of nurse fatigue on care delivery and (c) system factors that can either reduce or contribute to nurse fatigue. Eleven volunteers from a health care design focused nursing organisation participated in the focus group.

RESULTS

Twenty-seven design elements across four environmental categories were identified in this study as impacting fatigue. The effects of fatigue were found to have implications at the individual level (nurse and patient), the organisational level and the profession at large. Fatigue effects were found to be cumulative.

CONCLUSION(S)

Findings suggest that the PHE can have a substantial impact on nurse fatigue and contribute to profound effects with patient and staff safety implications.

IMPLICATIONS FOR NURSING MANAGEMENT

This study provides nursing managers, hospital administrators, nurses and designers with evidence for utilizing the PHE to mitigate and prevent nurse fatigue.

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 effects of environmental factors in waiting rooms on anxiety among patients undergoing coronary angiography: A randomized controlled trial

BACKGROUND

According to Florence Nightingale's hypothesis, the environment can play a central role in the healing of the patient's body and mind. The nurse should, therefore, strive to provide a healing and stress-reducing environment for patients about to undergo invasive procedures.

AIMS

This study aimed to investigate the effects of environmental factors on anxiety as experienced by patients in waiting rooms prior to coronary angiography.

METHODS

In this randomized controlled trial, 200 patients undergoing coronary angiography in an urban area of Iran were assigned randomly to the following intervention groups: (1) nature sounds; (2) nature sounds and daylight; (3) nature sounds, daylight, and colour enhancements; and (4) control. Portable monitors were used to measure the patients' physiological indices upon admission and 30 and 60 minutes thereafter.

RESULTS

Patients who experienced environmental affecting interventions had significantly lower physiological indices of anxiety than the control group (P < 0.001). Some significance was demonstrated between the three interventions groups, with patients in the intervention group that experienced maximum environmental interventions demonstrating the most overall reduction in anxiety indices.

CONCLUSION

Environmental factors were shown to have a positive effect on the indices of anxiety experienced by patients waiting for the procedure of coronary angiography; this is therefore an area of study and practice worthy of further development.

An Empirical Examination of Nursing Units in China Based on Nurse Experience

OBJECTIVES:

To create opportunities to increase nursing staff's satisfaction and operational efficiency and eventually improve nurses' experiences through better design in unit layout.

BACKGROUND:

The majority of research performed on nursing units in China only focused on the spatial design itself, and few studies examined the nursing unit empirically based on nurses' experience. Nursing units need to be designed with understanding nurses' behavior and experience in China.

METHOD:

A mixed-method approach was conducted in four double-corridor nursing units in China. Observation and interview data were collected to explore how physical environments for managing administrative duties, medications, and caring patient were used in nursing units.

RESULTS:

The most frequent activities were communication, medication, and patient-care activities. The places in which nurses spent the most of theirs working times were the nurse station (NS), patient room, workstation on wheels (WoW), and medication room. The important clinical work spaces were the patient room, NS, WoW, medication room, doctor's office, disposal room, examining room, and back corridor. The important traffic linkages were between NS and medication room, patient room and WoW, and medication room and patient room.

CONCLUSIONS:

This article revealed the frequency of nurse activities; how they spent their time; how they use the clinical spaces; identified important clinical spaces, linkages, and driver of inefficiency in nursing work and nursing unit design; and finally generated recommendations for double-corridor nursing unit design in China which can be used by medical planner, hospital administrator.

ICU nurses' experiences of environmental elements and their meaning for patient care at an ICU: A qualitative content analysis

In an intensive care unit (ICU), the environment is highly technological and staff are constantly present. The aim of this study was to describe environmental elements of an ICU room that nurses consider central for their provision of care. Data were collected using photovoice – photographs and in-depth interviews – and analysed using a qualitative content analysis approach. The care environment highly affected ICU nurses, in particular some elements such as medical equipment, work stations and beds. These were considered as an aid, but due to confined space some care was abstained from, maintaining privacy and confidentiality were a challenge, which led to frustration and stress. To provide care in an environment with good lightning, reduced noise and adequate space increases the wellbeing of the nurses, which indicates that an investment in a better care environment would be worthwhile.

Behavioral Mapping of Patient Activity to Explore the Built Environment During Rehabilitation

AIM

To explore the use of a rehabilitation-focused behavioral mapping method to identify changes in patient physical activity, location, and social interaction following the relocation of a rehabilitation ward.

BACKGROUND

Rehabilitation wards are unique healthcare environments where patient activity is encouraged to improve recovery. Little is known about the impact of building design on patient behavior within a rehabilitation setting. We examined this issue when a rehabilitation ward was relocated without altering other aspects of the healthcare service.

METHOD

The setting was a publicly funded inpatient general rehabilitation ward with a separate therapy area. Before and after ward relocation, patient behavior (location, physical, and social activities) was observed at 10-min intervals between 8:00 a.m. and 5:00 p.m. Patients and staff performed their usual activities during data collection.

RESULTS

Twenty-three patients participated in the old ward and 24 in the new ward, resulting in 1,150 and 1,200 observation time points, respectively. Patient location and behaviors were similar between wards ( p > .05). Participants were in bedrooms for more than half of the observations (67% old ward, 58% new ward), sitting down (62.8% old ward, 59.0% new ward), and alone (42.0% old ward, 38.0% new ward). Design features, such as separation of the therapy area and ward, may have impacted on patient behavior.

CONCLUSIONS

The rehabilitation-focused behavioral mapping method provided a rich description of relevant patient behaviors, indicating that it is a feasible and useful method for exploring the impact of the built environment in rehabilitation settings.

Environmental Design for End-of-Life Care: An Integrative Review on Improving the Quality of Life and Managing Symptoms for Patients in Institutional Settings

CONTEXT

The environment in which end-of-life (EOL) care is delivered can support or detract from the physical, psychological, social, and spiritual needs of patients, their families, and their caretakers.

OBJECTIVES

This review aims to organize and analyze the existing evidence related to environmental design factors that improve the quality of life and total well-being of people involved in EOL care and to clarify directions for future research.

METHODS

This integrated literature review synthesized and summarized research evidence from the fields of medicine, environmental psychology, nursing, palliative care, architecture, interior design, and evidence-based design.

RESULTS

This synthesis analyzed 225 documents, including nine systematic literature reviews, 40 integrative reviews, three randomized controlled trials, 118 empirical research studies, and 55 anecdotal evidence. Of the documents, 192 were peer-reviewed, whereas 33 were not. The key environmental factors shown to affect EOL care were those that improved 1) social interaction, 2) positive distractions, 3) privacy, 4) personalization and creation of a home-like environment, and 5) the ambient environment. Possible design interventions relating to these topics are discussed. Examples include improvement of visibility and line of sight, view of nature, hidden medical equipment, and optimization of light and temperature.

CONCLUSION

Studies indicate several critical components of the physical environment that can reduce total suffering and improve quality of life for EOL patients, their families, and their caregivers. These factors should be considered when making design decisions for care facilities to improve physical, psychological, social, and spiritual needs at EOL.

The impact of windows and daylight on acute-care nurses' physiological, psychological, and behavioral health

OBJECTIVE

To investigate the physiological and psychological effects of windows and daylight on registered nurses.

BACKGROUND

To date, evidence has indicated that appropriate environmental lighting with characteristics similar to natural light can improve mood, alertness, and performance. The restorative effects of windows also have been documented. Hospital workspaces generally lack windows and daylight, and the impact of the lack of windows and daylight on healthcare employees' well being has not been thoroughly investigated.

METHODS

Data were collected using multiple methods with a quasi-experimental approach (i.e., biological measurements, behavioral mapping, and analysis of archival data) in an acute-care nursing unit with two wards that have similar environmental and organizational conditions, and similar patient populations and acuity, but different availability of windows in the nursing stations.

RESULTS

Findings indicated that blood pressure (p < 0.0001) decreased and body temperature increased (p = 0.03). Blood oxygen saturation increased (p = 0.02), but the difference was clinically insignificant. Communication (p < 0.0001) and laughter (p = 0.03) both increased, and the subsidiary behavior indicators of sleepiness and deteriorated mood (p = 0.02) decreased. Heart rate (p = 0.07), caffeine intake (p = 0.3), self-reported sleepiness (p = 0.09), and the frequency of medication errors (p = 0.14) also decreased, but insignificantly.

CONCLUSIONS

The findings support evidence from laboratory and field settings of the benefits of windows and daylight. A possible micro-restorative effect of windows and daylight may result in lowered blood pressure and increased oxygen saturation and a positive effect on circadian rhythms (as suggested by body temperature) and morning sleepiness.

The Impact of Operating Room Layout on Circulating Nurse’s Work Patterns and Flow Disruptions: A Behavioral Mapping Study

Aim:

To assess how the adjacencies of functionally different areas within operating rooms (ORs) can influence the circulating nurse’s (CN) workflow patterns and disruptions.

Background:

The CN plays a significant role in promoting patient safety during surgical procedures by observing, monitoring, and managing potential threats at and around the surgical field. Their work requires constant movement to different parts of the OR to support team members. The layout of the OR and crowded and cluttered environment might impact the CN’s workflow and cause disruptions during the surgery.

Method:

A convenience sample of 25 surgeries were video recorded and thematically coded for CN’s activities, locations, and flow disruptions. The OR layout was categorized into transitional zones and functional zones (workstations, supply zones, support zones, and sterile areas around the surgical table). CN’s activities were classified into patient-, equipment-, material-, and information-related activities. Flow disruptions included those related to environmental hazards and layout.

Results:

The CN traveled through multiple zones during 91% of the activities. The CN’s workstation acted as a main hub from which the CN made frequent trips to both sides of the surgical table, the foot of the OR table, supply zones, and support zones. Transitional zones accounted for 58.3% of all flow disruption that the CN was involved in whereas 28% occurred in areas surrounding the OR bed.

Conclusion:

The similarity of the movement and flow disruption patterns, despite variations in OR layout, highlighted the adjacencies required between major zones that CNs regularly visit. These optimum adjacencies should be considered while designing ORs such that they are more efficient and safer.

The Importance of Specific Workplace Environment Characteristics for Maximum Health and Performance: Healthcare Workers' Perspective

OBJECTIVE

To examine the importance of specific workplace environment characteristics for maximum health and performance, assigned by healthcare employees, and how they relate to the nature of their work.

METHODS

A cross-sectional mixed-method study was conducted with content analysis and robust regression models to examine the relationship between workplace environment characteristics and perceived importance in promoting health and performance.

RESULTS

Our findings suggest that perceptions of key environment characteristics that safeguard health and performance in healthcare workplaces may vary by employee sex, setting, and nature of healthcare work involved. Theme and model descriptions of the influence of these factors on participant perceptions are provided.

CONCLUSIONS

Employee feedback on workplace characteristics that impact health and performance could be instrumental in determining the priorities of workplace design.

Territories of Engagement in the Design of Ecohumanist Healthcare Environments

Background:

Increasingly, architectural and allied designers, engineers, and healthcare facility administrators are being challenged to demonstrate success in adroitly identifying and contextualizing ever-shifting and expanding spheres of knowledge with respect to the role of energy conservation and carbon neutrality in healthcare treatment environments and their immediate exterior environs.

Aim:

This calls for making sense of an unprecedented volume of information on building energy usage and interdigitizing complex and at times contradictory goals with the daily requirements of building occupants. Ecohumanist Design Strategies: In response, a multidimensional framework is put forth with the aim of advancing theory and practice in the realm of designers’, direct caregivers’, and administrators’ engagement with ecohumanist design strategies in the creation of ecohumanist healthcare environments.

Conclusions:

Ten territories for engagement are presented that both individually and collectively express salient themes and streams of inquiry in theory and practice, within an operative framework placing the patient, the patient’s significant others, and the caregiver at the center of the relationship between the built environment and occupant well-being.

Natural environments, ancestral diets, and microbial ecology: is there a modern "paleo-deficit disorder"? Part I

Famed microbiologist René J. Dubos (1901-1982) was an early pioneer in the developmental origins of health and disease (DOHaD) construct. In the 1960s, he conducted groundbreaking experimental research concerning the ways in which early-life experience with nutrition, microbiota, stress, and other environmental variables could influence later-life health outcomes. He also wrote extensively on potential health consequences of a progressive loss of contact with natural environments (now referred to as green or blue space), arguing that Paleolithic experiences have created needs, particularly in the mental realm, that might not be met in the context of rapid global urbanization. He posited that humans would certainly adapt to modern urban landscapes and high technology, but there might be a toll to be paid in the form of higher psychological distress (symptoms of anxiety and depression) and diminished quality of life. In particular, there might be an erosion of humanness, exemplified by declines in altruism/empathy. Here in the first of a two-part review, we examine contemporary research related to natural environments and question to what extent Dubos might have been correct in some of his 50-year-old assertions.
