Lean Design of the Pediatric Intensive Care Unit Patient Room for Efficient and Safe Care Delivery.

BACKGROUND: The pediatric intensive care unit (PICU) is an environment where seriously ill children receive complex care, delivered mostly by specialty-trained nurses (registered nurses [RNs]) who must perform multiple high-level tasks. With stressors on healthcare systems at an all-time high, design that optimizes RN workflow has taken on a renewed imperative. OBJECTIVES: To employ a multimodal approach (1) to identify environmental factors in the PICU patient room that contribute to caregiver workflow inefficiencies, (2) to optimize safety by identifying high-touch surfaces that cause hospital-acquired infections, (3) to develop human-centered design recommendations. METHODS: This mixed-method case study was conducted in a 23-bed urban hospital PICU. The activities, movements, and workflows of 13 RNs were recorded using spatial movement mapping, behavioral mapping, and clinical activity mapping. Frequency of RN contact with surfaces was documented to assess relative infection transmission risk. Face-to-face interviews were conducted with RNs to elicit their views on care delivery and their physical work environment. RESULTS: Direct patient care occupied 50% of RNs' time. Of the direct patient care workflow activities recorded, 26% were to prepare for care around the bedside, while 27% were for random travel between clean and soiled areas. The surfaces most frequently touched were (1) patient bedrails, (2) intravenous pumps and poles, (3) tubing and medical equipment, and (4) vital sign monitors. CONCLUSION: Value-added tasks account for only about 20% of nurses' work. Combining technology and strategic interior design to streamline workflow and enhance infection prevention optimizes efficiency and empowers frontline providers to maximize their time at the bedside performing value-added tasks.

Development and palliative care staff reactions to a sleep regulation educational intervention.

BACKGROUND: In palliative care, sleep and circadian rhythm problems are common symptoms. Nonpharmacological interventions are available; however, health care providers are not aware of these or lack the knowledge to effectively implement in practice. This study reports the content and design development of the PRIME™ (Program for Improving & Managing Environments for Sleep) sleep online educational intervention as well as the evaluation of the intervention by practicing nurses with a focus on perceived acceptability and satisfaction. METHODS: Development of the education employed a multi-step process that assesses the current state of the science in this area (literature reviews), the needs of regional target recipients (hospice/palliative care staff), expert recommendations and views of a national pool of hospice/palliative workers. A cross-sectional, descriptive study with key staff informants evaluated the acceptability and usability of the modules using both scale-response items to rate the content and design of the modules and overall satisfaction and five open-response questions to suggest changes to the educational intervention. RESULTS: Among 31 palliative care professionals, most rated the content and design favorably. A total of 20 participants provided suggestions to improve the educational intervention. Their comments were categorized into six themes: Integration into Practice; Content, Exercises and Material Provided by Modules; User Interface and Design; and Adapt and Expand Modules for Public, Family and Caregivers. CONCLUSIONS: The data suggest that the PRIME™ educational intervention can be an effective tool to train direct-care palliative care professionals on interventions for use in their daily practice. We also demonstrated that the educational intervention is feasible to deliver online and that the online modules appealed to respondents, suggesting that future delivery of the educational intervention can use the same or similar modes of presentation.

Leveraging Daily Social Experiences to Motivate Healthy Aging.

Models of healthy aging highlight the motivating influence of social connections. Social experiences constantly shape our thoughts and behaviors throughout daily life, and these daily processes slowly and consistently influence our health and well-being. In this article, we discuss research that has moved from cross-sectional laboratory designs emphasizing individual behaviors to more naturalistic within-person paradigms linking daily social experiences to emotional, cognitive, and physical well-being. We mention research gaps that need to be filled to advance our knowledge of the powerful forces of the social environment for motivating healthy aging. We also offer future directions to move this research forward. We conclude with an outlook on how to leverage these powerful forces in novel intervention approaches that are sensitive to the constantly changing nature of the person and the environment.

Motivation and Healthy Aging at Work.

The aims of this paper were to review theoretical and empirical research on motivation and healthy aging at work and to outline directions for future research and practical applications in this area. To achieve these goals, we first consider the World Health Organization's (WHO) definition of healthy aging in the context of paid employment and life-span development in the work domain. Second, we describe contemporary theoretical models and cumulative empirical findings on age, motivation, and health and well-being at work, and we critically discuss to what extent they are consistent with the WHO's definition of healthy aging. Finally, we propose several directions for future research in the work context that are aligned with the WHO's definition of healthy aging, and we describe a number of interventions related to the design of work environments and individual strategies to promote the motivation for healthy aging at work.

Sociodemographic and Job Characteristics Influence Environmental Strategies Used to Manage Workplace Sleepiness.

OBJECTIVE: Suboptimal alertness and sleepiness impact work performance, health, and safety in many industries. We aimed to identify key environmental factors that workers view as supportive for reducing sleepiness and to examine the relationship between worker and job characteristics and identified sleepiness remedies. METHODS: We conducted a mixed-method (qualitative and quantitative) cross-sectional study analyzing data from a representative sample of 496 workers in New York State. RESULTS: Changing air ventilation (29.2%), natural lighting (17.1%), and room temperature (14.9%) were the environmental strategies deemed most important for managing workplace sleepiness. Strategy selection differed by sociodemographic (income and education) and job characteristics (indoor/outdoor, sedentary/mobile, and cognitive/physical labor). CONCLUSIONS: Customization of workplace environmental factors in a manner cognizant of workers' needs and sociodemographic and job characteristics could increase the use of evidence-based strategies to reduce sleepiness.

Palliative Design Meets Palliative Medicine: A Strategic Approach to the Design, Construction, and Operation of Healthcare Facilities to Improve Quality of Life and Reduce Suffering for Patients, Families, and Caregivers.

A built environment designed to be appropriate for palliative care can make a profound difference for people with life-limiting illnesses. The built environment affects a patient's quality of life, the management of physical and psychological symptoms, and the quality of social interactions with loved ones and caregivers. This article is informed by the emerging trends in the research and practice in the disciplines of architecture, design, medicine, and nursing. The article is intended to provide a definition of palliative design and invite discussion of its potential impact on patients, families, and caregivers. Our goal is to initiate conversation about palliative design, foster sharing of experiences and feedback among building professionals, and discuss future paths for formal adoption into practice.

Non-pharmacological solutions to sleep and circadian rhythm disruption: voiced bedside experiences of hospice and end-of-life staff caregivers.

BACKGROUND: Sleep disturbance is a significant issue, particularly for patients with advanced terminal illness. Currently, there are no practice-based recommended approaches for managing sleep and circadian disruptions in this population. To address this gap, a cross-sectional focus group study was performed engaging 32 staff members at four hospices/end-of-life programs in three demographically diverse counties in New York State. METHODS: Participants responded to structured open-ended questions. Responses were transcribed and subjected to qualitative content analysis. The themes and recommendations for improved practice that emerged were tabulated using Atlas TI qualitative software. RESULTS: This report details the experiences of hospice and end-of-life care staff in managing sleep and circadian disruptions affecting patients and analyzes their recommendations for improving care. Caregivers involved in the study described potential interventions that would improve sleep and reduce circadian disruptions. They particularly highlighted a need for improved evaluation and monitoring systems, as well as sleep education programs for both formal and informal caregivers. CONCLUSIONS: The voiced experiences of frontline hospice and end-of-life caregivers confirmed that disruption in sleep and circadian rhythms is a common issue for their patients and is not effectively addressed in current research and practice. The caregivers' recommendations focused on management strategies and underscored the need for well-tested interventions to promote sleep in patients receiving end-of-life care. Additional research is needed to examine the effectiveness of systematic programs that can be easily integrated into the end-of-life care process to attenuate sleep disturbances.

A systematic review of non-pharmacological interventions to improve nighttime sleep among residents of long-term care settings.

BACKGROUND: Disturbances in sleep and circadian rhythms are common among residents of long-term care facilities. In this systematic review, we aim to identify and evaluate the literature documenting the outcomes associated with non-pharmacological interventions to improve nighttime sleep among long-term care residents. METHODS: The Preferred Reporting Items for Systematic Reviews guided searches of five databases (MEDLINE, Embase, CINAHL, Scopus, and Cochrane Library) for articles reporting results of experimental or quasi-experimental studies conducted in long-term care settings (nursing homes, assisted-living facilities, or group homes) in which nighttime sleep was subjectively or objectively measured as a primary outcome. We categorized each intervention by its intended use and how it was administered. RESULTS: Of the 54 included studies evaluating the effects of 25 different non-pharmacological interventions, more than half employed a randomized controlled trial design (n = 30); the others used a pre-post design with (n = 11) or without (n = 13) a comparison group. The majority of randomized controlled trials were at low risk for most types of bias, and most other studies met the standard quality criteria. The interventions were categorized as environmental interventions (n = 14), complementary health practices (n = 12), social/physical stimulation (n = 11), clinical care practices (n = 3), or mind-body practices (n = 3). Although there was no clear pattern of positive findings, three interventions had the most promising results: increased daytime light exposure, nighttime use of melatonin, and acupressure. CONCLUSIONS: Non-pharmacological interventions have the potential to improve sleep for residents of long-term care facilities. Further research is needed to better standardize such interventions and provide clear implementation guidelines using cost-effective practices.

An Integrative Review of Nonpharmacological Interventions to Improve Sleep among Adults with Advanced Serious Illness.

BACKGROUND: Sleep fragmentation is common among those with advanced serious illness. Nonpharmacological interventions to improve sleep have few, if any, adverse effects and are often underutilized in these settings. OBJECTIVE: We aimed to summarize the literature related to nonpharmacological interventions to improve sleep among adults with advanced serious illness. METHODS: We systematically searched six electronic databases for literature reporting sleep outcomes associated with nonpharmacological interventions that included participants with advanced serious illness during the period of 1996-2016. RESULTS: From a total of 2731 results, 42 studies met the inclusion criteria. A total of 31 individual interventions were identified, each evaluated individually and some in combination with other interventions. Twelve of these studies employed either multiple interventions within an intervention category (n = 8) or a multicomponent intervention consisting of interventions from two or more categories (n = 5). The following intervention categories emerged: sleep hygiene (1), environmental (6), physical activity (4), complementary health practices (11), and mind-body practices (13). Of the 42 studies, 22 demonstrated a statistically significant, positive impact on sleep and represented each of the categories. The quality of the studies varied considerably, with 17 studies classified as strong, 17 as moderate, and 8 as weak. CONCLUSIONS: Several interventions have been demonstrated to improve sleep in these patients. However, the small number of studies and wide variation of individual interventions within each category limit the generalizability of findings. Further studies are needed to assess interventions and determine effectiveness and acceptability.

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.

Strategies to Improve Quality of Life at the End of Life: Interdisciplinary Team Perspectives.

This ethnographic study draws on the experiences of members of interdisciplinary care teams working with end-of-life care patients to identify strategies to improve quality of life through care practices. We surveyed 133 staff and volunteers (physicians, physician assistants, nurse practitioners, registered nurses, social workers, chaplains, administrators, and volunteers) who provide end-of-life care to patients in both home and institutional settings for 4 organizations in 2 counties in Upstate New York. Survey responses were analyzed using qualitative content analysis. The results identified numerous strategies to enhance and safeguard quality of life for end-of-life care patients and their family members. These strategies can be categorized into 6 domains: organization philosophy and mission; organizational policies; caregivers' behaviors and practices; symptom management; facility design, operation and management; and patient, family member, and caregiver experience. The diverse list of identified strategies indicates that improving care to address the unique, complex, multilayered dimensions of quality of life at the end of life requires a multidisciplinary approach and consistency among care providers, including administration, clinical management, front-line caregivers, and support staff. When all of these strategies are used in harmony, care can truly be enhanced.

Alert Workplace From Healthcare Workers' Perspective: Behavioral and Environmental Strategies to Improve Vigilance and Alertness in Healthcare Settings.

OBJECTIVE: This study aims to identify the behavioral and environmental strategies that healthcare workers view as helpful for managing sleepiness, improving alertness, and therefore optimizing workplace safety. BACKGROUND: Reduced alertness is a common issue in healthcare work environments and is associated with impaired cognitive performance and decision-making ability as well as increased errors and injuries. METHOD: We surveyed 136 healthcare professionals at a primary care clinic, an acute care hospital, and a mental health clinic. Nonstructured, semistructured, and structured questionnaires were used to elicit relevant information which was analyzed using qualitative content analysis and logistic regression models, respectively. RESULTS: In order by frequency of endorsement: dietary intervention; physical mobility; cognitive, sensory, or social stimulation; personal lifestyle strategies; and rest/nap opportunities were reported as behavioral strategies used to address workplace alertness. Compared to other environmental features, daylight and thermal comfort were perceived to be more important to addressing workplace alertness ( p < .05). CONCLUSIONS: By optimizing the physical environment and organizational policies and providing education programs, we have an opportunity to support healthcare professionals in managing sleepiness and maintaining alertness at work. In addition, such system level interventions may reduce unhealthy choices such as frequent caffeine intake to keep alert. The development of multidisciplinary evidence-based guidelines is needed to address sleepiness and alertness to improve workplace safety in healthcare facilities.

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.

The influence of spatial configuration on the frequency of use of hand sanitizing stations in health care environments.

BACKGROUND: The lack of user-friendly, accessible, and visible hand sanitizing stations (HSSs) in health care environments are significant factors affecting low hand hygiene compliance rates among caregivers. OBJECTIVE: To determine whether the simulated parameters of visibility and global traffic flow score for an HSS can influence the frequency of use of that HSS. METHODS: Space syntax was used to measure virtual simulation of spatial layouts of 3 units to provide quantitative visibility and global traffic flow scores for each HSS. The frequency of use of HSSs was measured for 2 weeks in 3 units in a community hospital through electronic tracking with self-developed motion sensors. Behavioral observations were also conducted during the same period to validate hand hygiene data obtained through electronic tracking. Linear models were used to tests how much variance in use is accounted for when visibility and/or global traffic flow are included in the model. RESULTS: When the visibility score for an HSS increases (decrease), frequency of use of the HSS will increase (decrease) (F [5, 65] = 13.877; P < .001). When the global traffic flow score for an HSS increases (decrease), frequency of use of the HSS will increase (decrease) (F [5, 65] = 13.877; P < .001). CONCLUSIONS: This study proposed and validated a novel approach of using space syntax simulations to predict and optimize hand hygiene behavior.

Evidence-based practices to increase hand hygiene compliance in health care facilities: An integrated review.

BACKGROUND: Hand hygiene (HH) in health care facilities is a key component to reduce pathogen transmission and nosocomial infections. However, most HH interventions (HHI) have not been sustainable. AIMS: This review aims to provide a comprehensive summary of recently published evidence-based HHI designed to improve HH compliance (HHC) that will enable health care providers to make informed choices when allocating limited resources to improve HHC and patient safety. METHODS: The Medline electronic database (using PubMed) was used to identify relevant studies. English language articles that included hand hygiene interventions and related terms combined with health care environments or related terms were included. RESULTS: Seventy-three studies that met the inclusion criteria were summarized. Interventions were categorized as improving awareness with education, facility design, and planning, unit-level protocols and procedures, hospital-wide programs, and multimodal interventions. Past successful HHIs may not be as effective when applied to other health care environments. HH education should be interactive and engaging. Electronic monitoring and reminders should be implemented in phases to ensure cost-effectiveness. To create hospitalwide programs that engage end users, policy makers should draw expertise from interdisciplinary fields. Before implementing the various components of multimodal interventions, health care practitioners should identify and examine HH difficulties unique to their organizations. CONCLUSIONS: Future research should seek to achieve the following: replicate successful HHI in other health care environments, develop reliable HHC monitoring tools, understand caregiver-patient-family interactions, examine ways (eg, hospital leadership, financial support, and strategies from public health and infection prevention initiatives) to sustain HHC, and use simulated lab environments to refine study designs.

Do cost savings from reductions in nosocomial infections justify additional costs of single-bed rooms in intensive care units? A simulation case study.

PURPOSE: Evidence shows that single-patient rooms can play an important role in preventing cross-transmission and reducing nosocomial infections in intensive care units (ICUs). This case study investigated whether cost savings from reductions in nosocomial infections justify the additional construction and operation costs of single-bed rooms in ICUs. MATERIALS AND METHODS: We conducted deterministic and probabilistic return-on-investment analyses of converting the space occupied by open-bay rooms to single-bed rooms in an exemplary ICU. We used the findings of a study of an actual ICU in which the association between the locations of patients in single-bed vs open-bay rooms with infection risk was evaluated. RESULTS: Despite uncertainty in the estimates of costs, infection risks, and length of stay, the cost savings from the reduction of nosocomial infections in single-bed rooms in this case substantially outweighed additional construction and operation expenses. The mean value of internal rate of return over a 5-year analysis period was 56.18% (95% credible interval, 55.34%-57.02%). CONCLUSIONS: This case study shows that although single-patient rooms are more costly to build and operate, they can result in substantial savings compared with open-bay rooms by avoiding costs associated with nosocomial infections.

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.

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. KEYWORDS: Critical care/intensive care, lighting, nursing, quality care, work environment.

Rethinking efficiency in acute care nursing units: analyzing nursing unit layouts for improved spatial flow.

OBJECTIVE: This paper introduces a new design tool to increase efficiency in acute care settings. This visual tool facilitates matching spatial flow with caregivers' workflow to reduce waste and redundancies, as recommended by Lean thinking. Providing work environments that protect caregivers from fatigue, interruptions, and redundancies can contribute to quality patient care. METHODS: By studying the Guidelines for Design and Construction of Health Care Facilities and reviewing the literature, the authors identified the main clinical spaces supporting nursing care and their important linkages. Space syntax, a diagrammatic analysis of relationships, was used to decode spatial relationships among the clinical spaces in five case studies. The movement distributions were measured and possible conflicts with focus-demanding tasks, such as noise and interruptions, were identified. The information was summarized in a visual diagram providing the "syntactic anatomy" of the most important work spaces. RESULTS: The main clinical spaces were the following: (1) patient corridor; (2) nurses' station; (3) medication area; (4) clean room; (5) soiled room; (6) physicians' dictation area; (7) report room; (8) restricted nourishment area; (9) equipment storage; and (10) unrestricted nourishment area. The report room, nourishment area, and physician workspace showed strong linkages to the patient corridor and nurses' station, although such spaces were not clearly discussed in the design guidelines. The most caregiver movement occurs in the patient corridor and nurses' station. These areas pose the greatest possibility of interruptions by persons. The results were translated into a visual design efficiency checklist. CONCLUSION: Illustrating the spatial order of the support spaces-and comparing that to use patterns-enables designers to reduce the movement sequences nurses undertake when accessing resources and identify where the flow is disrupted by "displaced" functions.
