Design Strategies to Improve Emergency Departments' Performance During Mass Casualty Incidents: A Survey of Caregivers

Patient flow management in biological events: a scoping review

INTRODUCTION

Biological Events affect large populations depending on transmission potential and propagation. A recent example of a biological event spreading globally is the COVID-19 pandemic, which has had severe effects on the economy, society, and even politics,in addition to its broad occurrence and fatalities. The aim of this scoping review was to look into patient flow management techniques and approaches used globally in biological incidents.

METHODS

The current investigation was conducted based on PRISMA-ScR: Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. All articles released until March 31, 2023, about research question were examined, regardless of the year of publication. The authors searched in databases including Scopus, Web of Science, PubMed, Google scholar search engine, Grey Literature and did hand searching. Papers with lack of the required information and all non-English language publications including those with only English abstracts were excluded. Data extraction checklist has been developed Based on the consensus of authors.the content of the papers based on data extraction, analyzed using content analysis.

RESULTS

A total of 19,231 articles were retrieved in this study and after screening, 36 articles were eventually entered for final analysis. Eighty-four subcategories were identified,To facilitate more precise analysis and understanding, factors were categorised into seven categories: patient flow simulation models, risk communication management, integrated ICT system establishment, collaborative interdisciplinary and intersectoral approach, systematic patient management, promotion of health information technology models, modification of triage strategies, and optimal resource and capacity management.

CONCLUSION

Patient flow management during biological Events plays a crucial role in maintaining the performance of the healthcare system. When public health-threatening biological incidents occur, due to the high number of patients, it is essential to implement a holistic,and integrated approach from rapid identification to treatment and discharge of patients.

Adapting to Change: A Systematic Literature Review of Environmental Flexibility in Emergency Departments

PURPOSE

This study aimed to offer a comprehensive analysis of distinct design strategies identified, evaluated, or discussed in the existing literature that promote environmental flexibility in the context of emergency departments (EDs).

BACKGROUND

EDs are subject to constant changes caused by several factors, including seasonal disease trends, the emergence of new technologies, and surges resulting from local or global disasters, such as mass casualty incidents or pandemics. Thus, integrating flexibility into ED design becomes crucial to effectively addressing these evolving needs.

METHODS

A systematic search was conducted in four databases: CINAHL, MEDLINE, PubMed, and ScienceDirect, in addition to a hand search. A two-stage review process was employed to determine the final list of included articles based on the inclusion criteria. Included studies were evaluated for quality, and findings were categorized using a hybrid deductive and inductive coding approach.

RESULTS

From the initial yield of 900 records, 22 studies met the inclusion criteria and were included in the final full-text review. The identified design strategies were organized into five categories: modifiability (n = 13 articles), versatility (n = 8 articles), tolerance (n = 6 articles), convertibility (n = 4 articles), and scalability (n = 7 articles). Specific design strategies under each category are reported in detail.

CONCLUSIONS

Our findings suggest that most flexibility design solutions are based on anecdotal evidence or descriptive studies, which carry less weight in terms of reliable support for conclusions. Therefore, more studies employing quantitative, relational, or causal designs are recommended.

Stakeholder experiential knowledge as evidence in redesigning health-care facilities for improved usability

Purpose

Evidence-based design (EBD) is traditionally limited to using empirical research findings based on randomized controlled trials. The purpose of this study is to explore stakeholder experiential knowledge as alternate credible evidence in redesigning health-care facilities for improved usability.

Design/methodology/approach

This research, based on critical participatory action research, involved a case study of redesign and post-occupancy evaluation (POE) of an emergency department (ED) at Holy Family Hospital, Techiman, Ghana. Observation, interviews and document analysis were used to collect data in the redesign and POE. The data was analyzed through directed content analysis.

Findings

Findings indicate that the redesign interventions, generated from stakeholder experiential knowledge, led to improved effectiveness, efficiency and satisfaction in the ED. This presents stakeholder experiential knowledge as alternate credible evidence in EBD. Furthermore, the POE revealed that open and flexible spatial arrangement, zoning care areas according to severity, and providing staff-support amenities are some redesign interventions for improving ED usability.

Practical implications

Compared to the hard and controlled nature of experimental research knowledge, the soft and fluid experiential knowledge of stakeholders could be more useful for health-care redesign process, especially in iteratively structuring design thinking and making choices.

Originality/value

This paper contributes to theory by validating and illustrating stakeholder experiential knowledge as credible evidence for EBD. Practically, it provides strategies, based on POE findings, for designing EDs to improve usability.

Toward Building Surge Capacity: Potentially Effective Spatial Configurations in Emergency Departments

BACKGROUND

Emergency departments (EDs) have been struggling with overcrowding issues for years. Some spatial configurations have been proposed to improve ED performance in facing overcrowding. Despite similarities with mass casualty incidents (MCIs), when demand for care exceeds the capacity, little is documented about the application of the proposed configurations during MCIs to improve surge capacity.

OBJECTIVES

We aimed to explore the potential of spatial configurations that have been proposed to handle ED overcrowding in daily operations so as to improve surge capacity during MCIs.

METHODS

Using an online Likert-scale survey, 11 spatial design strategies were rated by ED care teams in terms of their potential to improve surge capacity during MCIs.

RESULTS

Responses from 72 participants revealed that establishing an in-house lab was perceived as the most potential strategy, followed by rapid care area, internal waiting rooms, and in-house imaging. In contrast, separate entrance and exit doors, as well as decentralized nurse stations, were perceived as the least potential strategies but also exhibited the most variance in response. Respondents' comments implied that their choice of in-house ancillary services was primarily to improve communication and to reduce turnaround time and risk of errors. Their choice of rapid care and internal waiting areas related to improved flexibility.

CONCLUSIONS

Understanding clinicians' perspectives on potentially effective spatial configurations aids in implementing balanced strategies to better equip EDs to handle overcrowding in daily operations and manage surges during MCIs.

Efficiency and Teamwork in Emergency Departments: Perception of Staff on Design Interventions

OBJECTIVES

The goal of this study is twofold: (1) identifying design strategies that enhance efficiency and support teamwork in emergency departments (EDs) and (2) identifying design features that contribute to the spread of COVID-19, based on staff perception.

BACKGROUND

Due to increasing ED visits annually, an efficient work environment has become one of the main concerns in designing EDs. According to the literature, an efficient work environment and teamwork improve healthcare outcomes and positively impact staff satisfaction. During the COVID-19 pandemic, EDs faced various changes such as workflow and space usage. Few studies explored staff perceptions about the influence of design features on efficiency, teamwork, and the COVID-19 spread.

METHOD

An online survey with 14 open- and closed-ended questions was distributed among ED staff members to collect data about unit design features that impact efficiency, teamwork, and the COVID-19 spread.

RESULTS

The central nursing station was one of the preferred configurations that increased efficiency and teamwork in EDs. Decentralizing disposal rooms in small-size EDs and decentralizing the medication room in large-size EDs with more than 65 exam rooms can decrease staff walking steps. Flexibility to expand treatment spaces on demand, one-way track circulation path, and changing the air pressure in COVID-19 treatment areas were some of the staff suggestions for future EDs.

CONCLUSION

The findings of this study contribute to the body of knowledge that EDs' physical environments can impact efficiency and teamwork among staff and, consequently, healthcare outcomes. Compartmentalization of the ED layout can reduce the spread of COVID-19.

Data-Driven Design Strategies to Address Crowding and Boarding in an Emergency Department: A Discrete-Event Simulation Study

OBJECTIVE

To address prolonged lengths of stay (LOS) in a Level 1 trauma center, we examined the impact of implementing two data-driven strategies with a focus on the physical environment.

BACKGROUND

Crowding in emergency departments (EDs) is a widely reported problem leading to increased service times and patients leaving without being seen.

METHODS

Using ED historical data and expert estimates, we created a discrete-event simulation model. We analyzed the likely impact of initiating care and boarding patients in the hallway (hallway care) instead of the exam rooms and adding a dedicated triage space for patients who arrive by emergency medical services (EMS triage) to decrease hallway congestion. The scenarios were compared in terms of LOS, time spent in exam rooms and hallway spaces, service time, blocked time, and utilization rate.

RESULTS

The hallway care scenario resulted in significantly lower LOS and exam room time only for EMS patients but when implemented along with the EMS triage scenario, a significantly lower LOS and exam room time was observed for all patients (EMS and walk-in). The combination of two simulated scenarios resulted in significant improvements in other flow metrics as well.

CONCLUSIONS

Our findings discourage boarding of admitted patients in ED exam rooms. If space limitations require that admitted patients be placed in ED hallways, designers and planners should consider enabling hallway spaces with features recommended in this article. Alternative locations for boarding should be prioritized in or out of the ED. Our findings also encourage establishing a triage area dedicated to EMS patients in the ED.
