The effect of hospital unit layout on nurse walking behavior

Optimizing Nurse Workflow Efficiency: An Examination of Nurse Walking Behavior and Space Accessibility in Medical Surgical Units

OBJECTIVE

This study aimed to investigate the effect of spatial adjacencies on nurses' walking patterns and the subsequent impact on staff satisfaction with perceived accessibility and adjacency-related issues.

BACKGROUND

Recognizing the crucial importance of spatial adjacencies in healthcare facilities is essential, as they significantly affect staff morale, fatigue management, operational efficiency, error reduction, and overall patient care excellence, highlighting the need for objective assessments to evaluate the impact of facility layout and space configuration on workflow patterns and staff satisfaction in patient care units.

METHODS

Integrating on-site observations with survey data, we explored how spatial adjacencies affect staff walking behavior and satisfaction in two med-surgical unit floors.

RESULTS

The findings highlighted a significant frequency of movements between nurse stations, patient rooms, and medication areas. Regression analysis identified several contributing factors to staff satisfaction, including the proximity of supplies, team visibility, ease of access across departments, and the location of equipment rooms. Specifically, satisfaction with the proximity of supplies was positively associated with increased provider satisfaction with workflow, quality of care, and workplace. Additionally, valuable feedback from staff revealed concerns regarding break room placement, medication area functionality, and disparities in the availability of supplies.

CONCLUSION

This study highlighted the critical need for carefully planned spatial adjacency strategies to enhance workflow efficiency and raise clinical staff satisfaction within healthcare facilities. The actionable insights gleaned from this research offer valuable direction to architects, healthcare administrators, and design professionals, enabling the creation of environments that positively resonate with healthcare providers and improve healthcare operations.

A co-designed health information system implementation into residential aged care: A mixed-method evaluation

INTRODUCTION

Internationally, the adoption of technology into residential aged care settings has been slow and fraught with multiple challenges for residents, staff and service providers. The aim of this study was to evaluate the acceptability, efficiency, and quality of health information system implementation into aged care.

METHODS

Three-stage, mixed-methods participatory action research, concurrent with the natural experiment of a co-designed health information system implementation into a 169-bed aged care home in Australia. Data were collected pre-, during, and post implementation between 2019 and 2021. Qualitative data included focus groups, interviews, and observations. Quantitative data included work observations, pedometers, record audits, incident reports and staff and resident surveys. There were 162 participants composed of 65 aged care residents, 90 staff, and 7 managers/consultants.

RESULTS

Improved work efficiency included reduced staff time searching for information (6%); reduced nurse time on documentation (20.4% to 6.4%), and 25% less steps. Documentation improvement included resident assessments (68% to 96%); resident-focused goals (56% to 88%) and evaluations (31% to 88%). The staff reported being better equipped to manage the 'delicacies of dignity'.

CONCLUSION

Implementation of a health information system into a residential aged care facility was associated with improved resident-focused care and staff efficiency.

CLINICAL RELEVANCE

Technology can support nurses and care staff to spend more time with residents in residential aged care homes, improve the quality of resident care, and assist meeting regulatory reporting requirements. Flexible and tailored co-design strategies can enhance both effectiveness and success of technology implementation into residential aged care.

A new children's hospital with a larger floor space, single rooms, and V-shaped ward design: A pre-post evaluation of nurse time providing patient care and nurse, patient, and family experiences

BACKGROUND

The impact of hospital building design on patients, families and nurses related to nursing care interactions is not well understood. This study reports a pre-post intervention study to understand the effects of the move to a new children's hospital in Perth, Australia, on nurse workflow activities and on patient, family, and nurse experiences.

METHODS

We used a pre-post explanatory sequential design involving observation of nurse work tasks; measurement of the Practice Environment Scale and Nurse Work Index; weekly surveys of nurse, patient and family experiences; and nurse focus groups and interviews with patients and families. Survey data were analysed using linear regression; qualitative data analysis used a thematic approach.

RESULTS

Nurse time spent walking almost doubled (p < 0.001), from an estimated 10 min at T1 (pre-move) to around 20 min at T4 (12 months post-move), but there was no difference in nurse time providing patient care (p = 0.114). The Practice Environment Scale and Nurse Work Index showed significantly reduced scores for nursing foundations for quality of care (adjusted mean difference -0.08, p = 0.016) and staffing and resource adequacy (adjusted mean difference -0.19, p < 0.001).This fall was mirrored in nurse experience surveys with a reduction in mean scores from T1 to T3 (3 months post-move) of -0.7 (p < 0.001) and from T1 to T4 of -0.4 (p = 0.002). Thematic analysis of qualitative data found that initial challenges appeared to reduce over time. Nurses reported difficulties managing workflow in the new wards and feelings of exhaustion at T3, but this changed to more positive accounts at T4. For patients and families there was a tension between leaving the old and familiar, enjoying the light and space of the new and shared observations that nurses appeared to be busier at T3. At T4, these experiences had changed to 'being a family in hospital' and confidence that a nurse was always close by.

CONCLUSIONS

Both benefits and challenges of the new hospital design were encountered from the perspective of nurses, patients, and families. Nurses spent double the time walking in the new environment, but time spent providing patient care was unchanged. Over time, the initial practice challenges reduced as nurses adapted to working in the new environment.

Developing a simulation tool to quantify biomechanical load and quality of care in nursing

Nursing is a high musculoskeletal disorder (MSD) risk job with high workload demands. This study combines Digital Human Modelling (DHM) and Discrete Event Simulation (DES) to address the need for tools to better manage MSD risk. This novel approach quantifies physical-workload, work-performance, and quality-of-care, in response to varying geographical patient-bed assignments, patient-acuity levels, and nurse-patient ratios. Lumbar loads for 86 care-delivery tasks in an acute care hospital unit were used as inputs in a DES model of the care-delivery process, creating a shift-long time trace of the biomechanical load. Peak L4/L5 compression and moment were 3574 N and 111.58 Nm, respectively. This study reports trade-offs in all three experiments: (i) increasing geographical patient-bed assignment distance decreased L4/L5 compression (8.8%); (ii) increased patient-acuity decreased L4/L5 moment (4%); (iii) Increased nurse-patient ratio decreased L4/L5 compression (10%) and moment (17%). However, in all experiments, Quality of care indicators deteriorated (20, 19, and 29%, respectively). Practitioner Summary: This research has the potential to support decision-makers by developing a simulation tool that quantifies the impact of varying operational and design-policies in terms of biomechanical-load and quality of care. The demonstrator-model reports: as geographical patient-bed distance, patient-acuity levels, and nurse-patient ratios increase, biomechanical-load reduces, and quality of care deteriorates.

Investigations into the impact of nursing unit layout on critical care nurses

Background

Nurses’ work environment has apparent implications for maximizing their productivity, satisfaction, and improving patient care.

Objectives

This study aimed to explore the influence of three nursing unit spatial layouts on critical care nurses’ satisfaction and walking behavior at a university hospital.

Methods

The research used a comparative design by administering a standardized questionnaire, recording walking steps and distances using pedometers, and tracking nurses’ walking behavior. Thirty-six critical care nurses working on the morning shift consented to participate in the research.

Results

The study results showed a relationship between the spatial layout of intensive care units (ICUs) and nurses' satisfaction and walking behavior. Questionnaire results indicated statistically significant variations in nurses' satisfaction with the location of the nursing station, the arrangement of patients' rooms, the availability of family space, and the unit's auditory privacy. Nurses in ICU1 were more satisfied with the nursing station's placement and the availability of family space inside patient rooms, while nurses in ICU2 were more satisfied with the patient bed arrangement and the unit's aural privacy than nurses in other units. The pedometer readings and movement maps revealed significant differences in nurses' walking patterns across the three ICUs. The steps, distances, and movement diagrams demonstrated that ICU1 with private rooms outperformed the other units owing to the nurse station's placement and accessibility to patients and support rooms.

Conclusion

This study concludes that the ICU design impacts nurses' satisfaction and behavior. The optimum placement of nursing stations, patients' beds, and supporting room reduces walking distance and thus increases nurses’ satisfaction and performance.

•

Nurses' satisfaction with their work environment is critical for delivering high-quality healthcare services.

•

Hospitals that want to improve the job performance of their nurses must establish a supportive work environment for them.

•

Hospitals should encourage nurses to take an active role in making decisions about their work environment.

•

The findings from this study will contribute to the existing literature from a cross-cultural perspective.

An NSGA-II Algorithm with Adaptive Local Search for a New Double-Row Model Solution to a Multi-Floor Hospital Facility Layout Problem

A well-designed hospital facility layout planning process will enable improvements in operational efficiency, health outcomes, and patients’ medical experience. Older hospital facility layouts are likely to be based only on their designer’s experience, extant legal regulations, and other historical constraints. In this paper, we propose a solution to a multi-floor hospital facility layout problem in a hospital in Shanghai, China, based on a double-row model in which all departments are arranged into two rows on each floor. In this model, some fixed facilities are also taken into consideration. Two objectives, namely minimizing the total movement distance of patients and maximizing the total closeness rating score, are considered. An NSGA-II (nondominated sorting genetic algorithm II) algorithm with an adaptive local search operator has been developed to search for Pareto-optimal solutions. Experimental results show that our algorithm is able to solve model requirements successfully, the local search operator performs well, and the obtained results outperform the present layout in both the objectives.

Smart Intravenous Infusion Dosing System

Intravenous (IV) infusion therapy allows the infusion fluid to be inserted directly into the patient’s vein. It is used to place medications directly into the bloodstream or for blood transfusions. The probability that a hospitalized patient will receive some kind of infusion therapy, intravenously, is 60–80%. The paper presents a smart IV infusion dosing system for detection, signaling, and monitoring of liquid in an IV bottle at a remote location. It consists of (i) the sensing and computation layer—a system for detection and signaling of fluid levels in the IV bottle and a system for regulation and closing of infusion flow, (ii) the communication layer—a wireless exchange of information between the hardware part of the system and the client, and (iii) the user layer—monitoring and visualization of IV therapy reception at a remote location in real time. All layers are modular, allowing upgrades of the entire system. The proposed system alerts medical staff to continuous and timely changes of IV bottles, which can have positive effects on increasing the success of IV therapy, especially in oncology patients. The prescribed drip time of IV chemotherapy for the full effect of cytostatics should be imperative.

Viable bacterial communities on hospital window components in patient rooms

Previous studies demonstrate an exchange of bacteria between hospital room surfaces and patients, and a reduction in survival of microorganisms in dust inside buildings from sunlight exposure. While the transmission of microorganisms between humans and their local environment is a continuous exchange which generally does not raise cause for alarm, in a hospital setting with immunocompromised patients, these building-source microbial reservoirs may pose a risk. Window glass is often neglected during hospital disinfection protocols, and the microbial communities found there have not previously been examined. This pilot study examined whether living bacterial communities, and specifically the pathogens Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile (C. difficile), were present on window components of exterior-facing windows inside patient rooms, and whether relative light exposure (direct or indirect) was associated with changes in bacterial communities on those hospital surfaces. Environmental samples were collected from 30 patient rooms in a single ward at Oregon Health & Science University (OHSU) in Portland, Oregon, USA. Sampling locations within each room included the window glass surface, both sides of the window curtain, two surfaces of the window frame, and the air return grille. Viable bacterial abundances were quantified using qPCR, and community composition was assessed using Illumina MiSeq sequencing of the 16S rRNA gene V3/V4 region. Viable bacteria occupied all sampled locations, but was not associated with a specific hospital surface or relative sunlight exposure. Bacterial communities were similar between window glass and the rest of the room, but had significantly lower Shannon Diversity, theorized to be related to low nutrient density and resistance to bacterial attachment of glass compared to other surface materials. Rooms with windows that were facing west demonstrated a higher abundance of viable bacteria than those facing other directions, potentially because at the time of sampling (morning) west-facing rooms had not yet been exposed to sunlight that day. Viable C. difficile was not detected and viable MRSA was detected at very low abundance. Bacterial abundance was negatively correlated with distance from the central staff area containing the break room and nursing station. In the present study, it can be assumed that there is more human traffic in the center of the ward, and is likely responsible for the observed gradient of total abundance in rooms along the ward, as healthcare staff both deposit more bacteria during activities and affect microbial transit indoors. Overall, hospital window components possess similar microbial communities to other previously identified room locations known to act as reservoirs for microbial agents of hospital-associated infections.

Advancing evidence-based healthcare facility design: a systematic literature review

Healthcare facility design is a complex process that brings together diverse stakeholders and ideally aligns operational, environmental, experiential, clinical, and organizational objectives. The challenges inherent in facility design arise from the dynamic and complex nature of healthcare itself, and the growing accountability to the quadruple aims of enhancing patient experience, improving population health, reducing costs, and improving staff work life. Many healthcare systems and design practitioners are adopting an evidence-based approach to facility design, defined broadly as basing decisions about the built environment on credible and rigorous research and linking facility design to quality outcomes. Studies focused on architectural options and concepts in the evidence-based design literature have largely employed observation, surveys, post-occupancy study, space syntax analysis, or have been retrospective in nature. Fewer studies have explored layout optimization frameworks, healthcare layout modeling, applications of artificial intelligence, and layout robustness. These operations research/operations management approaches are highly valuable methods to inform healthcare facility design process in its earliest stages and measure performance in quantitative terms, yet they are currently underutilized. A primary objective of this paper is to begin to bridge this gap. This systematic review summarizes 65 evidence-based research studies related to facility layout and planning concepts published from 2008 through 2018, and categorizes them by methodology, area of focus, typology, and metrics of interest. The review identifies gaps in the existing literature and proposes solutions to advance evidence-based healthcare facility design. This work is the first of its kind to review the facility design literature across the disciplines of evidence-based healthcare design research, healthcare systems engineering, and operations research/operations management. The review suggests areas for future study that will enhance evidence-based healthcare facility designs through the integration of operations research and management science methods.

Impacts of Nursing Unit Design on Visibility and Proximity and Its Influences on Communication, Privacy, and Efficiency

OBJECTIVES

This study examines the role of visibility and proximity on nurse communication patterns, perception of privacy, and efficiency in double-corridor nursing units.

BACKGROUND

Nurses are extremely important for the quality of healthcare. The literature suggests that visibility and proximity have a substantial impact on the delivery of care and staff experience. However, few studies have empirically examined nursing units in China.

METHOD

Questionnaire surveys, observations, and simulations of medication administration tasks were employed.

RESULTS

Visibility and proximity influenced communication patterns, perceptions of privacy, and efficiency. The type of wall in the medication room could impact nurses' perception of privacy and efficiency. A partial glass wall in the medication room could achieve balance between privacy and visibility. A medication room that is adjacent to and is easily accessed from the nurse station (NS) could provide efficient communication and efficient work. The partition type between the NS and the doctor's office and the layout of the medication room could impact communication patterns. The relative position of the NS, medication room, and disposal room could influence the flow of medication administration tasks, and a geographically contiguous spatial layout could enhance work efficiency.

CONCLUSIONS

The findings contribute to the body of knowledge on the impact of visibility and proximity on nurses' communication patterns, perception of privacy, and efficiency. Recommendations to improve the design of double-corridor nursing units are also provided.

Layout Planning in Healthcare Facilities: A Systematic Review

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

Simulation-based optimization to improve hospital patient assignment to physicians and clinical units

A fundamental activity in hospital operations is patient assignment, which we define as the process of assigning hospital patients to specific physician services and clinical units based on their diagnosis. When the preferred assignment is not possible, typically due to capacity limits, hospitals often allow for overflow, which is the assignment of patients to other services and/or units. Overflow accelerates assignment, but can also reduce care quality and increase length of stay. This paper develops a discrete-event simulation model to evaluate different assignment strategies. Using a simulation-based optimization approach, we evaluate and heuristically optimize these strategies accounting for expected hospital and physician profit, care quality and patient waiting time. We apply the model using data from the University of Chicago Medical Center. We find that the strategies that use heuristically optimized designation of overflow services and units increase expected profit relative to the capacity-based strategy in which overflow patients are assigned to a service and unit with the most available capacity. We also find further improvement in the strategy that uses heuristically optimized overflow services and units as well as a holding unit that holds patients until a bed in their primary or secondary unit becomes available. Additionally, we demonstrate the effects of these strategies on other performance measures such as patient concentration, waiting time, and outcomes.

Decentralized Nurse Stations: A Methodology for Using Research to Guide Design Decisions

PURPOSE

The purpose of this methodology is to define a process for facility planning teams to use to ensure research findings are used to guide decision making in the design process.

BACKGROUND

Over the past decade and a half, research in health facility design has developed and the body of knowledge has grown significantly, but at the same time, the process for incorporating these findings into the design process has been less defined. This methodology evolved out of the desire to develop a structured process to integrate recent research findings into the planning and programming process at the user group and planning team level.

METHOD

This two-phase methodology consists of, first, reviewing recent, relevant research on the topic, classifying the findings into positive and negative attributes and, then, summarizing the attributes by category on a summary table and in a brief narrative. The second phase consists of reviewing the research to identify operational and facility strategies that can be used to mitigate the inconsistent and negative attributes identified.

RESULTS

In the case study, as a result of this process, one inconsistent attribute and three negative attributes were identified. In the second phase, potential research-based operational and facility strategies were identified to mitigate the inconsistent and negative attributes identified. This information served as the basis for making design decisions.

CONCLUSIONS

This methodology presents an organized, efficient process for organizing and providing relevant research findings to a facility planning team to use in evaluating a new healthcare design concept and making research-based design decisions.

Visitors’ use of corridors in internal medicine wards

Purpose

This paper aims to analyze visitors’ waiting behavior in corridors of an internal medicine ward in relation to concepts of territoriality and privacy.

Design/methodology/approach

Waiting activities, visitors’ room numbers and duration of activities were recorded on a floor plan. Results were tallied according to behavioral and architectural zones in which the activity took place.

Findings

Locations that are near patient rooms that provide visual and auditory access are largely used as territorial areas for non-privacy-required activities. Ends of corridors, secondary corridors and staircases were mainly used for activities that required some level of privacy such as grieving.

Research limitations/implications

As is true with post-occupancy evaluations in other single buildings, this research may not be generalizable to all internal medicine wards. Future research could measure whether responding to visitors’ spatial needs could result in lower density and sense of crowding in the corridors, as well as reduce stress and task interruptions and increase efficiency of patient-check rounds.

Practical implications

The findings indicate that internal medicine wards should include waiting areas near the patient rooms for visitors to be able to keep visual and auditory connection with their patients, as well as areas that provide privacy. This may help lower density, sense of crowding, distraction of medical staff, stress and burn-out and errors, as well as increase the efficiency of patient checks.

Originality/value

The ways in which architectural design of internal medicine corridors can support visitors’ activities and environmental needs such as territoriality and privacy is an issue that is rarely examined. This paper also adds an example from a non-Western culture, to a literature that is dominated by examples from Western cultures.

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.

A pilot study exploring the relationship between the use of mobile technologies, walking distance, and clinical decision making among rural hospital nurses

Providing evidence-based information at the point of care for time-poor nurses may lead to better clinical care and patient outcomes. Smartphone applications (apps) have the advantage of providing immediate access to information potentially increasing time spent with patients. This small-scale pre-post survey study explored the impact a smartphone app had on the distance nurses walked and their perceived clinical decision-making ability. A total of 20 nurses working in a rural hospital medical/surgical unit participated. The findings suggest that the use of the smartphone app did not decrease nurses’ walking distance. Nor did using the app enhances nurses’ perception of their clinical decision-making ability. However, there was a statistically significant increase in confidence in the app over time (F(1,16) = 5.416, p = 0.033, partial η2= 0.253), suggesting that providing training opportunities including time to learn how to use smartphone applications has the potential to enhance nurses work.

"Everything Happens in the Hallways": Exploring User Activity in the Corridors at Two Rehabilitation Units

OBJECTIVES

This research aimed to examine the role of the corridors in specialist inpatient rehabilitation units to inform future design of these spaces.

BACKGROUND

In healthcare settings, such as rehabilitation units, corridors have often been designed simply as spaces allowing movement between other locations. However, research suggests that corridors may be places where important social and care-related activities take place. How corridors are used and understood by patients and staff in inpatient rehabilitation settings is unclear, and a greater understanding of the role of corridors in these settings could help to inform more supportive design of these spaces.

METHODS

Independent observations of user activity were conducted at a major metropolitan inpatient spinal injury unit (SIU) and brain injury unit (BIU). Interviews were conducted with SIU patients ( n = 12), and focus groups were conducted with SIU staff ( n = 23), BIU patients ( n = 12), and BIU staff ( n = 10).

RESULTS

Results from the observations showed that the corridors were used frequently across the day, particularly by staff. Thematic analysis of staff and patient experiences found three key themes describing how corridors were used: (1) moving around, (2) delivery and experiences of quality care, and (3) a "spillover space."

CONCLUSIONS

Results demonstrate that corridors not only have an important role as connective spaces but are also used as flexible, multipurpose spaces for delivery of quality care and patient experiences. Future design should consider how these spaces can more deliberately support and contribute to patient and staff experiences of rehabilitation.

Shifting Landscapes: The Impact of Centralized and Decentralized Nursing Station Models on the Efficiency of Care

Objective:

The focus of this research was to analyze the impact of decentralized and centralized hospital design layouts on the delivery of efficient care and the resultant level of caregiver satisfaction.

Background:

An interdisciplinary team conducted a multiphased pre- and postoccupancy evaluation of a cardiovascular service line in an academic hospital that moved from a centralized to decentralized model. This study examined the impact of walkability, room usage, allocation of time, and visibility to better understand efficiency in the care environment.

Method:

A mixed-methods data collection approach was utilized, which included pedometer measurements of staff walking distances, room usage data, time studies in patient rooms and nurses’ stations, visibility counts, and staff questionnaires yielding qualitative and quantitative results.

Results:

Overall, the data comparing the centralized and decentralized models yielded mixed results. This study’s centralized design was rated significantly higher in its ability to support teamwork and efficient patient care with decreased staff walking distances. The decentralized unit design was found to positively influence proximity to patients in a larger design footprint and contribute to increased visits to and time spent in patient rooms.

Conclusion:

Among the factors contributing to caregiver efficiency and satisfaction are nursing station design, an integrated team approach, and the overall physical layout of the space on walkability, allocation of caregiver time, and visibility. However, unit design alone does not solely impact efficiency, suggesting that designers must consider the broader implications of a culture of care and processes.

Process Mining-Based Method of Designing and Optimizing the Layouts of Emergency Departments in Hospitals

OBJECTIVE

This article proposes an approach to help designers analyze complex care processes and identify the optimal layout of an emergency department (ED) considering several objectives simultaneously. These objectives include minimizing the distances traveled by patients, maximizing design preferences, and minimizing the relocation costs.

BACKGROUND

Rising demand for healthcare services leads to increasing demand for new hospital buildings as well as renovating existing ones. Operations management techniques have been successfully applied in both manufacturing and service industries to design more efficient layouts. However, high complexity of healthcare processes makes it challenging to apply these techniques in healthcare environments.

METHOD

Process mining techniques were applied to address the problem of complexity and to enhance healthcare process analysis. Process-related information, such as information about the clinical pathways, was extracted from the information system of an ED. A goal programming approach was then employed to find a single layout that would simultaneously satisfy several objectives.

RESULTS

The layout identified using the proposed method improved the distances traveled by noncritical and critical patients by 42.2% and 47.6%, respectively, and minimized the relocation costs.

CONCLUSION

This study has shown that an efficient placement of the clinical units yields remarkable improvements in the distances traveled by patients.

Key Spatial Factors Influencing the Perceived Privacy in Nursing Units: An Exploration Study With Eight Nursing Units in Hong Kong

Aim:

This study examined how the spatial characteristics of patient beds, which are influenced by patient room design and nursing unit configuration, affect patients’ perceptions about privacy.

Background:

In the hospital setting, most patients expect a certain degree of privacy but also understand that their caregivers need appropriate access to them in order to provide high-quality care. Even veteran healthcare designers may struggle to create just the right balance between privacy and accessibility.

Methods:

A paper-based survey was conducted with 159 participants in Hong Kong—72 (45.3%) participants had been hospitalized and 87 (54.7%) participants had not—to document their selection of high-privacy beds, given simplified plans of eight nursing units. Two types of information, comprised of six variables, were examined for each bed. These include (1) room-level variables, specifically the number of beds per room and area per bed and (2) relational variables, including walking distance, directional change, integration, and control.

Results:

The results demonstrate that when asked to identify high-privacy beds, participants selected beds in patient rooms with fewer beds per room, a larger area per bed, and a longer walking distance to the care team workstation. Interestingly, the participants having been hospitalized also chose beds with a visual connection to the care team workstation as being high in privacy.

Conclusions:

The participants with hospitalization experience may be willing to accept a bed with reduced visual privacy, perhaps out of a concern for safety.

Space Syntax Analysis

Aim:

This article reviews and addresses various spatial measures that provide and facilitate accurate descriptions of different layout typologies with particular focus on healthcare facilities.

Background:

Evidence-based design is a field of study that emphasizes the importance of using credible data in order to influence the design process. It addresses whether/how the design and operation of buildings support positive health outcomes through a growing collection of solutions informed by research and practical knowledge. In order to acquire this knowledge, we must consider the environment in a very precise and measurable way, which can then be investigated quantitatively with regard to various human behaviors and cognitive processes.

Topical Headings:

Space Syntax theory and methods are concerned with understanding how spaces are arranged and connected to one another. It provides quantitative measures of individual spaces and of the entire layout, thereby achieving great accuracy. Space Syntax researchers have used graph theory to define spatial measures and have produced computer tools to quantify the relational properties of spaces and to provide numerical and display values for each. Moreover, they have developed more precise tools that can be embedded within basic Space Syntax concepts in order to augment the credibility of the acquired data.

Conclusion:

The study elaborates on the effectiveness of Space Syntax and its newly developed measures for the field of healthcare facility design and research. We present a comprehensive model that brings together these measures with their correlated behavioral and perceptual consequences, thereby providing a point of departure for further investigation and exploration.

The effect of hospital unit layout on nurse walking behavior

OBJECTIVE

To confirm a new method for the research question, "How do different hospital unit layouts affect nurses' walking behavior and distance?"

BACKGROUND

Concern is renewed regarding nurses' long walking distances because of the trend toward larger patient rooms with family areas inside, resulting in a larger overall unit size. Studies have found unit design characteristics that support nurses' efficient walking, but few have done it in units designed for patient- and family-centered care. To examine the effect of unit design on nurses' walking behavior, the authors propose a new method of observing a specific task.

METHODS

The authors observed nurses during the task of medication administration.

RESULTS

Contrary to their hypotheses, results showed: (1) Experienced nurses had more unnecessary stops and longer walking distances than new nurses because of interactions; and (2) nurses in the smaller wing of the unit walked more than those in the larger wing of the same unit. The authors posit that the closeness between the nurses' path to the medication supply room and the central nurses' station affected the frequency of interactions and prompted a deviation from the shortest and most efficient path during medication administration.

CONCLUSION

Observing a specific task to identify the effect of unit layout was effective, determining that overall unit shape or unit layout type might not be a good predictor of nurses' walking behavior; instead the characteristics of the path that connects functional spaces such as patient room and medication area might better predict nurses' walking behavior.

Research on nursing unit layouts: an integrative review

Purpose

– This paper aims to present an integrative review of the research studies on nursing unit layouts.

Design/methodology/approach

– Studies selected for review were published between 1956 and 2014. For the purpose of this review, a framework for integrative review was developed using research orientations. The three primary dimensions – technical, psychological and social – of the designed environment and various combinations of these dimensions were used to define the research orientations of these studies.

Findings

– Of all the publications reviewed for the paper, 21 presented technical orientations, 16 psychological orientations, 3 social orientations, 20 psychotechnical orientations, 10 sociotechnical orientations, 2 psychosocial orientations and 13 presented psychosociotechnical orientations. With only a few exceptions, several issues related to nursing unit layouts were investigated no more than one time in any one category of research orientations. Several other seemingly important issues including patient and family behavior and perception, health outcomes and social and psychosocial factors in relation to unit layouts have not been studied adequately.

Research limitations/implications

– Future studies on nursing unit layouts will need to focus on patient and family behavior and perception, health outcomes and social and psychosocial factors in different units. They will also need to focus on developing theories concerning the effects of layouts on the technical, psychological and social dimensions of nursing units.

Originality/value

– Despite a long history of research on nursing unit layouts, an integrative review of these studies is still missing in the literature. This review fills in the gap using a novel framework for integrative review developed based on research orientations.

Nurses' lived experiences of intensive care unit bed spaces as a place of care: a phenomenological study

BACKGROUND

The environment of an intensive care unit (ICU) is, in general, stressful and has an impact on quality of care in terms of patient outcomes and safety. Little is known about nurses' experiences, however, from a phenomenological perspective with regard to the critical care settings as a place for the provision of care for the most critically ill patients and their families.

AIM

The aim of this study was to explore nurses' lived experiences of ICU bed spaces as a place of care for the critically ill.

DESIGN AND METHODS

A combination of qualitative lifeworld interviews and photos --photovoice methodology --was used when collecting data. Fourteen nurses from three different ICUs participated. Data were analysed using a phenomenological reflective lifeworld approach.

FINDINGS

An outer spatial dimension and an inner existential dimension constitute ICU bed spaces. Caring here means being uncompromisingly on call and a commitment to promoting recovery and well-being. The meanings of ICU bed spaces as a place of care comprise observing and being observed, a broken promise, cherishing life, ethical predicament and creating a caring atmosphere.

CONCLUSIONS AND RELEVANCE TO CLINICAL PRACTICE

The architectural design of the ICU has a great impact on nurses' well-being, work satisfaction and the provision of humanistic care. Nurses need to be involved in the process of planning and building new ICU settings. There is a need for further research to highlight the quality of physical environment and its impact on caring practice.
