Abstract

Purpose

This work aims to integrate the concepts generated by a systematic literature review on patient flows in emergency departments (ED) to serve as a basis for developing a generic process model for ED.

Design/methodology/approach

A systematic literature review was conducted using PRISMA guidelines, considering Lean Healthcare interventions describing ED patients’ flows. The initial search found 141 articles and 18 were included in the systematic analysis. The literature analysis served as the basis for developing a generic process model for ED.

Findings

ED processes have been represented using different notations, such as value stream mapping and workflows. The main alternatives for starting events are arrival by ambulance or walk-in. The Manchester Triage Scale (MTS) was the most common protocol referred to in the literature. The most common end events are admission to a hospital, transfer to other facilities or admission to an ambulatory care system. The literature analysis allowed the development of a generic process model for emergency departments. Nevertheless, considering that several factors influence the process of an emergency department, such as pathologies, infrastructure, available teams and local regulations, modelling alternatives and challenges in each step of the process should be analysed according to the local context.

Originality/value

A generic business process model was developed using BPMN that can be used by practitioners and researchers to reduce the effort in the initial stages of design or improvement projects. Moreover, it’s a first step toward the development of generalizable and replicable solutions for emergency departments.

Abstract

Purpose

The complexity and interdisciplinarity of healthcare industry problems make this industry one of the attention centers of computer-based simulation studies to provide a proper tool for interaction between decision-makers and experts. The purpose of this study is to present a metamodel-based simulation optimization in an emergency department (ED) to allocate human resources in the best way to minimize door to doctor time subject to the problem constraints which are capacity and budget.

Design/methodology/approach

To obtain the objective of this research, first the data are collected from a public hospital ED in Brazil, and then an agent-based simulation is designed and constructed. Afterwards, three machine-learning approaches, namely, adaptive neuro-fuzzy inference system (ANFIS), feed forward neural network (FNN) and recurrent neural network (RNN), are used to build an ensemble metamodel through adaptive boosting. Finally, the results from the metamodel are applied in a discrete imperialist competitive algorithm (ICA) for optimization.

Findings

Analyzing the results shows that the yellow zone section is considered as a potential bottleneck of the ED. After 100 executions of the algorithm, the results show a reduction of 24.82 per cent in the door to doctor time with a success rate of 59 per cent.

Originality/value

This study fulfils an identified need to optimize human resources in an ED with less computational time.

Abstract

Purpose

Modern subway transportation systems need to satisfy increasing safety demands to rapidly evacuate passengers under hazardous emergency circumstances, such as fires, accidents or terrorist attacks, to reduce passenger injuries or life losses. The emergency evacuation capacity (EEC) of a subway station needs to be revised timely, in case passenger demand increases or the evacuation route changes in the future. However, traditional ways of estimating EEC, e.g. fire drills are time- and resource-consuming and are difficult to revise from time to time. The purpose of this study is to establish an intuitive modelling approach to increase the EEC of subway stations in a stepwised manner.

Design/methodology/approach

This study develops an approach to combine agent-based evacuation modelling and building information modelling (BIM) technology to estimate the total evacuation time of a subway station.

Findings

Evacuation time can be saved (33% in the studied case) from iterative improvements including stopping escalators running against the evacuation flow and modifying the geometry around escalator exits. Such iterative improvements rely on integrating agent-based modelling and BIM.

Originality/value

The agent-based model can provide a more realistic simulation of intelligent individual movements under emergency circumstances and provides precise feedback on locations of evacuation bottlenecks. This study also examined the effectiveness of two rounds of stepwise improvements in terms of operation or design to increase the EEC of the station.

Abstract

Scenarios are discussed in terms of their various uses in emergency planning and management. Their function in teaching programs is assessed with respect to various sorts of curricula for training emergency personnel. The format of scenarios is discussed and the potential for using the methodology creatively is explored. It is concluded that scenario methods are useful in developing such skills as time management, cognitive mapping, mediation, team management, and decision making under stress. A brief example of an emergency training scenario is presented and evaluated in terms of its teaching potential. Finally, scenarios are assessed in relation to other forms of modelling and simulation, such as table‐top games and field exercises, which are commonly used for training emergency managers.

Abstract

Purpose

The objectives of this article are to present the findings of a case study conducted to determine the optimal emergency egress time for the main library of King Fahd University of Petroleum and Minerals, Dhahran, Saudi Arabia, using an evacuation simulation model; discuss the importance of the use of evacuation simulation models to architects, fire protection engineers and facilities managers; and demonstrate the importance of using an evacuation simulation model in understanding evacuation performance and conducting building safety assessment.

Design/methodology/approach

The authors have reviewed the published literature in the field of evacuation analysis considering level of service (LOS) as a significant factor; studied the input requirements of the evacuation simulation model EVACNET4 and estimated the same for the library facility at King Fahd University of Petroleum & Minerals; and examined selected results and validated the same using FPETool.

Findings

The study revealed that the evacuation times obtained using both EVACNET4 and FPETool for the library are different and vary 49 seconds in magnitude.

Originality/value

Risk to life as a result of fire in buildings is a key concern for facility managers, architects and insurance companies. This study could be of practical help to fire protection engineers and facilities managers from the viewpoint of emergency evacuation planning in specific facilities, and to architects during the process of designing the spatial layout of the library facility, where even minor changes in the layout can have large impacts on egress time.

Abstract

Purpose

This paper aims to examine how media play a role in community responses to disaster. The authors explore how communication technology may allow new relationships between community groups and emergency agencies. The authors examine the context within which warnings and risk communication are interpreted by media services. The authors observe how, in an emergency context, the thinking about media may change from that of a linear framework of information provision to one of shared resources.

Design/methodology/approach

The authors focus on Second Life, a shared, online space which uses 3D graphic images to simulate a virtual environment. Second Life is posited as a media tool with clear advantages for the training of emergency services professionals and citizens in the community. The authors observe emergency training scenarios and advantages for training for critical thinking and decision-making.

Findings

The authors observe then how virtual worlds such as Second Life provide an online forum in which participants can interact, communicate and simulate action in a complex 3D graphic environment. Second Life may be a useful medium for simulating and testing geo-physical and social manoeuvres using the modeling tools. This may allow for collaborative decision-making in simulations which can prepare or rehearse people for emergency conditions. It may be useful in an emergency with information streamed and coordinated at a single online site. A shared network like Second Life may be shared by many people co-synchronously or a-synchronously, despite their geographic distance. Second Life applications may also be useful in the aftermath of emergencies for design and rebuilding, for analytical and educational purposes.

Research limitations/implications

It is clear that social networks like Second Life provide a valuable tool with which to learn about and share data and information about bushfires, community emergencies and safety precautions in a social setting. It can also provide, at the local level, a forum for community information and discussion, as well as for counselling and reconstruction in the aftermath.

Practical implications

The authors suggest that the range and flexibility of tools and their excellent geographic visualization and social networking functions may in future allow for learning and decision-making among diverse and disparate groups who can come together in virtual space. It is especially useful in remote communities as a means of uniting people who are otherwise isolated by distance or trapped in emergency situations. Second Life is useful for sharing information, organizational and local knowledge about disaster and mitigation management. This media-rich platform is valuable to a community that is increasingly adept with shared, 3D graphic computer interfaces.

Social implications

Applications like Second Life may provide a space where users can access a range of tools as a means of informing, educating, empowering and warning participants in emergency scenarios, both real and simulated. They are more than virtual spaces; they are also social spaces. A platform like Second Life may provide a virtual solution for such communication challenges especially where communities are too remote, too dispersed or even too many in number to be easily accessible in the field.

Originality/value

This paper contains new and significant information about emerging communication systems and platforms that may be of use to those researching and planning around disaster management, mitigation and resilience. It addresses the use of new techniques which are the result of innovation in technology, software design and network design. It applies a discussion of these techniques to several hypothetical and real-life scenarios to explore the potential for virtual tools as a way of providing enriched information, mapping and communication tools across a range of disaster response scenarios.

Abstract

Computer‐aided decision‐support tools are part and parcel of the emergency planning and management process today. Much is dependent on using modern technology to gather and analyse data on damage assessment, meteorology, demography, etc. and provide decision support for prevention/mitigation, response and recovery. Diverse technologies are merged to provide useful functions to aid the emergency planner/manager. Complexities arise when attempting to link several streams of technology to achieve a realistic, usable and reliable decision‐support tool. This discussion identifies and analyses the challenging issues faced in linking two technologies: simulation modelling and GIS, to design spatial decision‐support systems for evacuation planing. Experiences in designing CEMPS, a prototype designed for area evacuation planning, are drawn on to discuss relevant managerial, behavioural, processual and technical issues. Focus is placed on modelling evacuee behaviour, generating realistic scenarios, validation, logistics, etc. while also investigating future trends and developments.

Abstract

Purpose

This paper aims to highlight the crucial role of decision makers and emergency managers in reducing the unpleasant consequences of disasters.

Design/methodology/approach

An attempt has been made to clarify the measures for planning and implementation of training issues in earthquake emergency response for the emergency managers as an essential part at various managerial levels.

Findings

The paper reveals that, although the high‐level managers such as ministers are authoritative bodies for managing the routine problems of the country, in situations such as a “major emergency”, specific knowledge and experience of emergency issues are required for the emergency management to be successful. It also explores the ways and opportunities for achieving successful training programmes for the emergency managers.

Research limitations/implications

The existing challenges, including the lack of adequate background knowledge and experience in emergency management, insufficient time to train, the inadequacy of the required technical supporting tools, and other related issues, emerge, which need to be identified.

Practical implications

The research can be practically useful for emergency managers who are involved in response activities in disasters by providing suitable and appropriate recommendations for efficient training.

Originality/value

There are only a few works on training of earthquake emergency managers, especially in developing countries such as Iran.

Abstract

Following civilian disasters such as Piper Alpha, Hillsborough and King′s Cross, personnel professionals are rethinking the types of individuals needed to fill senior posts, considering the demands of responding to a serious emergency. Presents the results from a project designed to examine the current selection, training and assessment procedures for managers of offshore oil and gas installations in the North Sea, with particular emphasis on their ability to take command in the event of a serious offshore incident. Personnel and operations managers in 38 oil and gas exploration and production companies in the UK were interviewed. Characteristics sought in an offshore installation manager were leadership and command ability, communication skills, sound judgement, decisiveness and a stable disposition. Selection decisions were based predominantly on the candidate′s previous performance, appraisal reports and managerial recommendations rather than more formal methods such as interview panels, assessment centres or psychometric tests. An industry‐wide concern regarding managerial competence has led to increased use of emergency management simulations for training and assessment. The lack of formal assessments during the selection procedure is surprising, but the recent introduction of high fidelity, emergency management simulations present an additional source of valuable information on future candidates if assessment data are collected rigorously.
