Visibility-based layout of a hospital unit - An optimization approach.

A patient fall is one of the adverse events in an inpatient unit of a hospital that can lead to disability and/or mortality. The medical literature suggests that increased visibility of patients by unit nurses is essential to improve patient monitoring and, in turn, reduce falls. However, such research has been descriptive in nature and does not provide an understanding of the characteristics of an optimal inpatient unit layout from a visibility-standpoint. To fill this gap, we adopt an interdisciplinary approach that combines the human field of view with facility layout design approaches. Specifically, we propose a bi-objective optimization model that jointly determines the optimal (i) location of a nurse in a nursing station and (ii) orientation of a patient's bed in a room for a given layout. The two objectives are maximizing the total visibility of all patients across patient rooms and minimizing inequity in visibility among those patients. We consider three different layout types, L-shaped, I-shaped, and Radial; these shapes exhibit the section of an inpatient unit that a nurse oversees. To estimate visibility, we employ the ray casting algorithm to quantify the visible target in a room when viewed by the nurse from the nursing station. The algorithm considers nurses' horizontal visual field and their depth of vision. Owing to the difficulty in solving the bi-objective model, we also propose a Multi-Objective Particle Swarm Optimization (MOPSO) heuristic to find (near) optimal solutions. Our findings suggest that the Radial layout appears to outperform the other two layouts in terms of the visibility-based objectives. We found that with a Radial layout, there can be an improvement of up to 50% in equity measure compared to an I-shaped layout. Similar improvements were observed when compared to the L-shaped layout as well. Further, the position of the patient's bed plays a role in maximizing the visibility of the patient's room. Insights from our work will enable understanding and quantifying the relationship between a physical layout and the corresponding provider-to-patient visibility to reduce adverse events.

Library tools at the nurses' station: exploring information-seeking behaviors and needs of nurses in a war veterans nursing home.

Objectives: Analyze the information-seeking practices and identify the information and education needs of nurses in a war veterans nursing home. Develop an online toolkit for use at the nurses' stations to meet nurses' health information needs. Methods: Investigators employed mixed methods to determine the health information needs of the participating nurses at the skilled nursing facility using an online questionnaire and in-person observations. Resulting data was compared to determine how nurses' self-reported data corresponded with investigator observations. Results: Twenty-seven out of a total of thirty-five nurses responded to the online questionnaire. The study principal investigator also observed a total of twelve nurses working across all shifts. The online questionnaire asked nurses to identify when they need health information for an acute clinical scenario. Nurses self-reported feeling most confident in assessing falls and pain, followed by medication adherence and skin integrity. Issues most frequently encountered during observation of nurses were falls, interventions surrounding cognitive ability or dementia, and use of antibiotics. Nurses reported and were observed to consult colleagues most frequently, followed by drug handbooks and relying on nursing experience. Conclusion: Nurses in skilled nursing facilities will benefit from ready online access to current drug handbooks as well as information resources surrounding commonly encountered clinical issues and stated needs. An outcome of this project is an online toolkit site using a LibGuide created specifically for this purpose. Researchers purchased laptop computers that were installed at each of the nurses' stations to provide ready access to the toolkit site.

Web-Based Intravenous Fluid Treatment Monitoring Platform in Nursing Station.

BACKGROUND: Intravenous fluid treatment is the most common way to take care of inpatients. Because of the global pandemic, the number of inpatients is increasing rapidly, leading to constant demand in the contactless system. PURPOSE: In this article, we suggest a web-based intravenous fluid treatment monitoring platform in the nursing station to unburden the medical staff's workload.

Characteristics of Home-Visit Nursing Stations that Accept Children Requiring Long-Term Medical Care after Discharge from Neonatal Intensive Care Unit.

Many cultures are witnessing high-risk births due to the increasing trend of delayed childbearing. This has resulted in a higher proportion of children requiring long-term medical care (CLTM). The number of home-visit nursing stations available for pediatric patients should increase to provide care for CLTM at home. Through a questionnaire-based cross-sectional survey of 338 home-visit nursing station managers, this study aimed to identify the determinants of the acceptance of CLTM by analyzing the characteristics of the stations, managers, staff, and registered children, and the volume of home visits. Chi-squared tests and logistic regressions were applied to determine the independence of the variables of acceptance and analyze their significance, respectively. The response rate was 14.6%, the number of pediatric patients registered in the past was 914, and the average number of registered pediatrics was 2.7. The results indicate a correspondence between the increase in home visits by nursing staff and the number of CLTM accepted for home-visit nursing services after discharge from neonatal intensive care units. Additionally, stations whose managers have three or more years of pediatric care experience accept more CLTM, and their employees are better equipped to facilitate these acceptances. Nonetheless, the number of facilities with pediatric departments has declined; thus, nurses will face increasing difficulty gaining pediatric work experiences. Therefore, enhanced seminars and training on pediatric medical care for managers and nurses, as well as strengthened collaboration/coordination with pediatric wards, clinics, and multidisciplinary occupations should be implemented as countermeasures. Our findings illustrate issues and strategies for acceptance.

Designing for Efficiency: Examining the Impact of Centralized and Decentralized Nurse Stations on Interdisciplinary Care Processes.

OBJECTIVE: This study examined the impact of centralized and decentralized unit designs on an interdisciplinary team's perceptions of efficiency through the use of a preoccupancy and postoccupancy evaluation of a cardiovascular unit. BACKGROUND: During the premove study, the service line was housed across 4 separate locations, each with a centralized nurses' station. The postmove design was housed on 1 floor with decentralized stations. METHODS: For this qualitative study, 14 focus groups and 1 interview were conducted. Analysis of the data was guided by a developed framework for efficiency classified into 7 categories. RESULTS: Outcomes reveal that efficiency was impacted by issues including walking, access to supplies and equipment, proximity to staff, and overall unit configuration and size. CONCLUSIONS: Although the design of the decentralized unit positions staff members closer to patients, many feel isolated while the centralized units seemed to better promote staff proximity and access to supplies.

The Social Logic of Nursing Communication and Team Processes in Centralized and Decentralized Work Spaces.

This pre-post multi-method study explored how nurses made sense of changes in nurse station design and how they characterized communication processes within a hospital unit before and after it moved from an existing hospital into a newly designed trauma-1 level hospital. Quantitative observations (116 h) of real-time communication were gathered in both hospitals. Additionally, 41 nursing staff (nurses, nursing care technicians, nurse managers) participated in a qualitative study. Three months before moving, four focus groups were conducted with 16 nursing professionals working in traditional centralized nurse station units. One year later, four additional focus groups were conducted with 25 nursing staff in new decentralized units. The observational data resulted in two key findings: first, nursing staff participated in about 70 percent of interactions with nurses, techs, doctors, and families. Second, nursing communication decreased in decentralized units. In-depth qualitative analysis revealed that nursing communication was more frequent, relational and supportive in centralized spaces while distinguished by fragmentation and information exchange in decentralized units. Drawing upon theories of supportive design and healthcare systems, these findings illustrate how nurses in centralized units characterized communication as proximity, teamwork and relationships. Nurses in decentralized units described communication in terms of distance, fragmentation, and information exchange. Implications of this study suggest that centralized spaces may facilitate nursing communication while decentralized units are supportive of proximity to patients. Exploring how communication and design together constitute the logic of healthcare delivery contributes to our understanding of how communication processes comprise the social organization of nursing care.

[Study on the Issues Faced by Home-Visit Nursing Stations for Repletion and Reinforcement of Disasters Preparedness].

BACKGROUND: Amid concerns about the occurrence of large-scale disasters, preparation for such disasters is an emergency issue. PURPOSE: In this study, we clarified new burdens in repletion and reinforcement of disaster preparedness in home-visit nursing stations that support home care patients and their families. METHODS: A questionnaire survey was conducted in homevisit nursing stations of areas where large-scale disasters are predicted to occur. Based on the survey, the burdens in preparation were analyzed. RESULTS: Based on the obtained data, three categories were formed:"a burden related to presupposition of the preparation","a burden related to concretization of the preparation", and "a burden related to practice of the preparation". DISCUSSION: For an appropriate reduction in the burdens, a necessity for further studies was indicated; these included studies on the complete picture of suitable disaster preparedness for home care, studies on the development of models that enable practical, effective, and efficient preparation, and studies on positioning of the system.

Designing the Glucose Telemetry for Hospital Management: From Bedside to the Nursing Station.

PURPOSE OF THE REVIEW: Hospitalized patients with diabetes are monitored with point-of-care glucose testing. Continuous glucose monitoring (CGM) devices represent an alternative way to monitor glucose values; however, the in-hospital CGM use is still considered experimental. Most inpatient studies used "blinded" CGM properties and only few used the real-time/unblinded CGM features. One major limitation of the CGM devices is that they need to be placed at the patients' bedside, limiting any therapeutic interventions. In this article, we review the real-time/unblinded CGM use and share our thoughts about the development of future inpatient CGM systems. RECENT FINDINGS: We recently reported that glucose values can be wirelessly transmitted to the nursing station, providing remote continuous glucose monitoring. Future inpatient CGM devices may be utilized for patients at risk for hypoglycemia similarly to the way that we use cardiac telemetry to monitor hospitalized patients who are at increased risk for cardiac arrhythmias.

Do portable nursing stations within bays of hospital wards reduce the rate of inpatient falls? An interrupted time-series analysis.

Background: falls can negatively affect patients, resulting in loss of independence and functional decline and have substantial healthcare costs. Hospitals are a high-risk falls environment and regularly introduce, but seldom evaluate, policies to reduce inpatient falls. This study evaluated whether introducing portable nursing stations in ward bays to maximise nurse-patient contact time reduced inpatient falls. Methods: inpatient falls data from local hospital incident reporting software (Datix) were collected monthly (April 2014-December 2017) from 17 wards in Stoke Mandeville and Wycombe General Hospitals, the UK. Portable nursing stations were introduced in bays on these wards from April 2016. We used a natural experimental study design and interrupted time series analysis to evaluate changes in fall rates, measured by the monthly rate of falls per 1000 occupied bed days (OBDs). Results: the wards reported 2875 falls (April 2014-December 2017). The fallers' mean age was 78 (SD = 13) and 58% (1624/2817) were men. Most falls, 99.41% (2858/2875), resulted in none, low or moderate harm, 0.45% (13/2875) in severe harm and 0.14% (4/2875) in death. The monthly falls rate increased by 0.119 per 1000 OBDs (95% CI: 0.045, 0.194; P = 0.002) before April 2016, then decreased by 0.222 per 1000 OBDs (95% CI: -0.350, -0.093; P = 0.001) until December 2017. At 12 months post-intervention, the absolute difference between the estimated post-intervention trend and pre-intervention projected estimate was 2.84 falls per 1000 OBDs, a relative reduction of 26.71%. Conclusion: portable nursing stations were associated with lower monthly falls rates and could reduce inpatient falls across the NHS.

Care of the Injured Patients at Nursing Stations and during Air Medical Transport.

INTRODUCTION: Nursing stations are the only access point into the health care system for some communities and have limited capabilities and resources. We describe characteristics of patients injured in Northern Ontario who present to nursing stations and require transport by air ambulance. Secondary objectives are to compare interventions performed at nursing stations with those performed by flight paramedics and to identify systemic gaps in trauma care. METHODS: A retrospective cohort study was performed of all injured patients transported by air ambulance from April 1, 2014, to March 31, 2015. RESULTS: A total of 125 injured patients were transported from nursing stations. Blunt trauma accounted for 82.5% of injuries, and alcohol intoxication was suspected in 41.6% of patients. The most frequently performed interventions were intravenous fluids and analgesia. Paramedics administered oxygen 62.4% of the time, whereas nursing stations only applied in 8.8% of cases. Flight paramedics were the only providers to intubate and administer tranexamic acid, mannitol, or vasopressors. CONCLUSION: Care for patients at nursing stations may be improved by updating the drug formulary based on gap analyses. Further research should examine the role of telemedicine support for nursing station staff and the use of point-of-care devices to screen for traumatic intracranial hemorrhage.

[Identifying the Regional Features in the Visiting Nursing Station Trade Area Using GIS].

In order to clarify the characteristics of the area where the visiting nursing station is located, we conducted a study to identify the regional characteristics of the visiting nursing station in Ishikawa Prefecture, using geographical information system(GIS). We mapped the elderly population, aging rate, and location data for the visiting nursing station using QGIS, and created trade areas(Voronoi diagrams). The aging rate for each trade area is 22.4%(min 8.8% to max 44.6%), about 5 times. The difference in area is about 850 times as large as the central value of 9.2 km2(min 0.5 km2 to max 423.2 km2). In addition, there was a tendency for stations with a large trade area to have a higher aging rate than that of smaller stations. Understanding the characteristics of the area surrounding visiting nursing stations using GIS facilitates the clarification of potential needs and opportunities for providing visiting nursing services that are suitable for each area.

The Role of the Built Environment: How Decentralized Nurse Stations Shape Communication, Patient Care Processes, and Patient Outcomes.

Increasingly, health communication scholars are attending to how hospital built environments shape communication, patient care processes, and patient outcomes. This multimethod study was conducted on two floors of a newly designed urban hospital. Nine focus groups interviews were conducted with 35 health care professionals from 10 provider groups. Seven of the groups were homogeneous by profession or level: nursing (three groups), nurse managers (two groups), and one group each of nurse care technicians ("techs") and physicians. Two mixed groups were comprised of staff from pharmacy, occupational therapy, patient care facilitators, physical therapy, social work, and pastoral care. Systematic qualitative analysis was conducted using a conceptual framework based on systems theory and prior health care design and communication research. Additionally, quantitative modeling was employed to assess walking distances in two different hospital designs. Results indicate nurses walked significantly more in the new hospital environment. Qualitative analysis revealed three insights developed in relationship to system structures, processes, and outcomes. First, decentralized nurse stations changed system interdependencies by reducing nurse-to-nurse interactions and teamwork while heightening nurse interdependencies and teamwork with other health care occupations. Second, many nursing-related processes remained centralized while nurse stations were decentralized, creating systems-based problems for nursing care. Third, nursing communities of practices were adversely affected by the new design. Implications of this study suggest that nurse station design shapes communication, patient care processes, and patient outcomes. Further, it is important to understand how the built environment, often treated as invisible in communication research, is crucial to understanding communication within complex health care systems.

How Patients and Nurses Experience an Open Versus an Enclosed Nursing Station on an Inpatient Psychiatric Unit.

The inpatient environment is a critical space for nurses and patients in psychiatric settings. In this article, we describe nurses' and patients' perceptions of the inpatient environment both before the removal of a Plexiglas enclosure around a nurses' station and after its removal. Nurses had mixed feelings about the enclosure, reporting that it provided for confidentiality and a concentrated work space but also acknowledged the challenge of the barrier for communication with their patients. Patients unanimously preferred the nurses' station without the barrier, reporting increased feelings of freedom, safety, and connection with the nurses after its removal. It is important to consider the implications of environmental decisions in inpatient settings in order to promote a healthy workplace and healing environment for all community members.

Staff perceptions of patient visibility systems in acute care settings.

Patient care visibility technology systems provide real-time information about patient admissions, discharges, transport, clinical activities and housekeeping services, in order to enhance patient care and flow. This article reports the results of a descriptive study that explored healthcare professionals' perceptions of and attitudes to a patient care visibility technology system in an acute care setting. The results indicate that staff find the system user friendly, and are positive about its staff- and patient-focused characteristics. Overall, positive staff perceptions and acceptance imply positive use of the system. This study forms the basis for further research on the effects on the patient-care outcomes of healthcare professionals' use of these systems.

Intensive care unit design and mortality in trauma patients.

BACKGROUND: The architecture of medical care facilities ca affect the safety of a patient, but it is unknown if the architecture affects outcomes. We hypothesized that patients in rooms who are more visible from the central nursing station would experience better outcomes than those patients in less visible rooms. MATERIALS AND METHODS: A total of 773 patients admitted to the trauma intensive care service over a 12-mo period were retrospectively evaluated. Outcomes were hospital mortality and intensive care unit (ICU) length of stay (LOS). The unit is designed with a bank of high-visibility rooms (HVRs) directly across from the nursing station and two side sections of low-visibility rooms (LVRs). No formal triage occurs, but patients are prioritized to HVRs as available. RESULTS: Patients in the HVRs had a 16% mortality (52 of 320); meanwhile, the patients in the LVRs experienced an 11% mortality (49 of 448, P = 0.03). ICU mortality did not differ significantly when controlling for age, Charlson Comorbidity Index (CCI), Head Abbreviated Injury Score, and the Injury Severity Score (ISS) (P = 0.076). Age, CCI, Head Abbreviated Injury Score, and ISS did individually correlate with mortality (age: P = 0.0008; CCI: P = 0.017; and ISS: P < 0.0001). Visibility was not a predictor of ICU LOS or complications among survivors (mean ICU HVR LOS = 4.8 d; mean ICU LVR LOS = 4.7; P = 0.88, n = 661). Only ISS was a significant predictor of ICU LOS and complications (P < 0.0001). CONCLUSIONS: Trauma patient room placement within the ICU does not relate to mortality rate significantly when corrected for patient acuity. Instead, variables such as age, ISS, and CCI are associated with mortality. A policy of placing more critically ill patients in HVRs may prevent increased mortality in high-acuity patients.

Towards Legitimate Nursing Work? Historical Discursive Constructions of Abortion in The Canadian Nurse, 1950-1965.

To the detriment of women's health, the abortion work of nurses in Canada has gone largely unexamined and is not well understood. This historical discourse analysis examines discursive constructions of nurses' abortion work and ongoing renegotiations of professional identity in The Canadian Nurse from 1950 to 1965. By investigating what has shaped and continues to inform nurses' understandings and enactment of abortion work over time, I hope to contribute to a foundation from which to evaluate contemporary abortion services and to foster conditions that support nurses in providing safe abortion care.

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.

Impact of the physical environment of psychiatric wards on the use of seclusion.

BACKGROUND: The physical environment is presumed to have an effect on aggression and also on the use of seclusion on psychiatric wards. Multicentre studies that include a broad variety of design features found on psychiatric wards and that control for patient, staff and general ward characteristics are scarce. AIMS: To explore the effect of design features on the risk of being secluded, the number of seclusion incidents and the time in seclusion, for patients admitted to locked wards for intensive psychiatric care. METHOD: Data on the building quality and safety of psychiatric as well as forensic wards (n = 199) were combined with data on the frequency and type of coercive measures per admission (n = 23 868 admissions of n = 14 834 patients) on these wards, over a 12-month period. We used non-linear principal components analysis (CATPCA) to reduce the observed design features into a smaller number of uncorrelated principal components. Two-level multilevel (logistic) regression analyses were used to explore the relationship with seclusion. Admission was the first level in the analyses and ward was the second level. RESULTS: Overall, 14 design features had a significant effect on the risk of being secluded during admission. The 'presence of an outdoor space', 'special safety measures' and a large 'number of patients in the building' increased the risk of being secluded. Design features such as more 'total private space per patient', a higher 'level of comfort' and greater 'visibility on the ward', decreased the risk of being secluded. CONCLUSIONS: A number of design features had an effect on the use of seclusion and restraint. The study highlighted the need for a greater focus on the impact of the physical environment on patients, as, along with other interventions, this can reduce the need for seclusion and restraint.
