There is no consensus on where automated external defibrillators (AEDs) should be placed in rural communities to maximize impact on survival from cardiac arrest. In the community of Stokes County, North Carolina (USA) the Emergency Medical Services (EMS) system promotes cardiopulmonary resuscitation (CPR) public education and AED use with public access defibrillators (PADs) placed mainly in public schools, churches, and government buildings.
Hypothesis/Problem
This study tested the utilization of AEDs assigned to first responders (FRs) in their private-owned-vehicle (POV) compared to AEDs in fixed locations.
Methods
The authors performed a prospective, observational study measuring utilization of AEDs carried by FRs in their POV compared to utilization of AEDs in fixed locations. Automated external defibrillator utilization is activation with pads placed on the patient and analysis of heart rhythm to determine if shock/no-shock is indicated. The Institutional Review Board of Wake Forest University Baptist Health System approved the study and written informed consent was waived. The study began on December 01, 2012 at midnight and ended on December 01, 2013 at midnight.
Results
During the 12-month study period, 81 community AEDs were in place, 66 in fixed locations and 15 assigned to FRs in their POVs. No utilizations of the 66 fixed location AEDs were reported (0.0 utilizations/AED/year) while 19 utilizations occurred in the FR POV AED study group (1.27 utilizations/AED/year; P<.0001). Odds ratio of using a FR POV located AED was 172 times more likely than using a community fixed-location AED in this rural community.
Discussion
Placing AEDs in a rural community poses many challenges for optimal utilization in terms of cardiac arrest occurrences. Few studies exist to direct rural community efforts in placing AEDs where they can be most effective, and it has been postulated that placing them directly with FRs may be advantageous.
Conclusions
In this rural community, the authors found that placing AED devices with FRs in their POVs resulted in a statistically significant increase in utilizations over AED fixed locations.

Non-invasive positive pressure ventilation (NIPPV) is used to treat severe acute respiratory distress. Prehospital NIPPV has been associated with a reduction in both in-hospital mortality and the need for invasive ventilation.
Hypothesis/Problem
The authors of this study examined factors associated with NIPPV failure and evaluated the impact of NIPPV on scene times in a critical care helicopter Emergency Medical Service (HEMS). Non-invasive positive pressure ventilation failure was defined as the need for airway intervention or alternative means of ventilatory support.
Methods
A retrospective chart review of consecutive patients where NIPPV was completed in a critical care HEMS was conducted. Factors associated with NIPPV failure in univariate analyses and from published literature were included in a multivariable, logistic regression model.
Results
From a total of 44 patients, NIPPV failed in 14 (32%); a Glasgow Coma Scale (GCS) <15 at HEMS arrival was associated independently with NIPPV failure (adjusted odds ratio 13.9; 95% CI, 2.4-80.3; P=.003). Mean scene times were significantly longer in patients who failed NIPPV when compared with patients in whom NIPPV was successful (95 minutes vs 51 minutes; 39.4 minutes longer; 95% CI, 16.2-62.5; P=.001).
Conclusion
Patients with a decreased level of consciousness were more likely to fail NIPPV. Furthermore, patients who failed NIPPV had significantly longer scene times. The benefits of NIPPV should be balanced against risks of long scene times by HEMS providers. Knowing risk factors of NIPPV failure could assist HEMS providers to make the safest decision for patients on whether to initiate NIPPV or proceed directly to endotracheal intubation prior to transport.

The 2011, magnitude (M) 9, Great East Japan Earthquake and massive tsunami caused widespread devastation and left approximately 18,500 people dead or missing. The incidence of preventable disaster death (PDD) during the Great East Japan Earthquake remains to be clarified; the present study investigated PDD at medical institutions in areas affected by the Great East Japan Earthquake in order to improve disaster medical systems.
Methods
A total of 25 hospitals in Miyagi Prefecture (Japan) that were disaster base hospitals (DBHs), or had at least 20 patient deaths between March 11, 2011 and April 1, 2011, were selected to participate based on the results of a previous study. A database was created using the medical records of all patient deaths (n=868), and PDD was determined from discussion with 10 disaster health care professionals.
Results
A total of 102 cases of PDD were identified at the participating hospitals. The rate of PDD was higher at coastal hospitals compared to inland hospitals (62/327, 19.0% vs 40/541, 7.4%; P<.01). No difference was observed in overall PDD rates between DBHs and general hospitals (GHs); however, when analysis was limited to cases with an in-hospital cause of PDD, the PDD rate was higher at GHs compared to DBHs (24/316, 7.6% vs 21/552, 3.8%; P<.05). The most common causes of PDD were: insufficient medical resources, delayed medical intervention, disrupted lifelines, deteriorated environmental conditions in homes and emergency shelters at coastal hospitals, and delayed medical intervention at inland hospitals. Meanwhile, investigation of PDD causes based on type of medical institution demonstrated that, while delayed medical intervention and deteriorated environmental conditions in homes and emergency shelters were the most common causes at DBHs, insufficient medical resources and disrupted lifelines were prevalent causes at GHs.
Conclusion
Preventable disaster death at medical institutions in areas affected by the Great East Japan Earthquake occurred mainly at coastal hospitals. Insufficient resources (at GHs), environmental factors (at coastal hospitals), and delayed medical intervention (at all hospitals) constituted the major potential contributing factors. Further investigation of all medical institutions in Miyagi Prefecture, including those with fewer than 20 patient deaths, is required in order to obtain a complete picture of the details of PDD at medical institutions in the disaster area.

The objective of this study was to determine if modification of the Simple Triage and Rapid Treatment (START) system by the addition of an Orange category, intermediate between the most critically injured (Red) and the non-critical, non-ambulatory injured (Yellow), would reduce over- and under-triage rates in a simulated mass-casualty incident (MCI) exercise.
Methods
A computer-simulation exercise of identical presentations of an MCI scenario involving a 2-train collision, with 28 case scenarios, was provided for triaging to two groups: the Fire Department of the City of New York (FDNY; n = 1,347) using modified START, and the Emergency Medical Services (EMS) providers from the Eagles 2012 EMS conference (Lafayette, Louisiana USA; n = 110) using unmodified START. Percent correct by triage category was calculated for each group. Performance was then compared between the two EMS groups on the five cases where Orange was the correct answer under the modified START system.
Results
Overall, FDNY-EMS providers correctly triaged 91.2% of cases using FDNY-START whereas non-FDNY-Eagles providers correctly triaged 87.1% of cases using unmodified START. In analysis of the five Orange cases (chest pain or dyspnea without obvious trauma), FDNY-EMS performed significantly better using FDNY-START, correctly triaging 86.3% of cases (over-triage 1.5%; under-triage 12.2%), whereas the non-FDNY-Eagles group using unmodified START correctly triaged 81.5% of cases (over-triage 17.3%; under-triage 1.3%), a difference of 4.9% (95% CI, 1.5-8.2).
Conclusions
The FDNY-START system may allow providers to prioritize casualties using an intermediate category (Orange) more properly aligned to meet patient needs, and as such, may reduce the rates of over-triage compared with START. The FDNY-START system decreases the variability in patient sorting while maintaining high field utility without needing computer assistance or extensive retraining. Comparison of triage algorithms at actual MCIs is needed; however, initial feedback is promising, suggesting that FDNY-START can improve triage with minimal additional training and cost.

Aortic dissection is difficult to detect in the early phase due to a variety of symptoms. This report describes the prehospital setting of aortic dissection in terms of symptoms, treatment, and suspicion by the Emergency Medical Service (EMS) staff.
Basic Procedures
All patients in the Municipality of Gothenburg, Sweden, who, in 2010 and 2011, had a hospital discharge diagnosis of aortic dissection (international classification of disease (ICD) I 71,0) were included. The exclusion criteria were: age < 18 years of age and having a planned operation. This was a retrospective, descriptive study based on patient records. In the statistical analyses, Fisher's exact test and the Mann-Whitney U test were used for analyses of dichotomous and continuous/ordered variables.
Main findings
Of 92 patients, 78% were transported to the hospital by the EMS. The most common symptom was pain (94%). Pain was intensive or very intensive in 89% of patients, with no significant difference in relation to the use of the EMS. Only 47% of those using the EMS were given pain relief with narcotic analgesics. Only 12% were free from pain on admission to the hospital. A suspicion of aortic dissection was reported by the EMS staff in only 17% of cases. The most common preliminary diagnosis at the dispatch center (31%) and by EMS clinicians (52%) was chest pain or angina pectoris. In all, 79% of patients were discharged alive from the hospital (75% of those that used the EMS and 95% of those that did not).
Conclusion
Among patients who were hospitalized due to aortic dissection in Gothenburg, 78% used the EMS. Despite severe pain in the majority of patients, fewer than half received narcotic analgesics, and only 12% were free from pain on admission to the hospital. In fewer than one-in-five patients was a suspicion of aortic dissection reported by the EMS staff.

Risk assessment is a vital step in the disaster-preparedness continuum as it is the foundation of subsequent phases, including mitigation, response, and recovery.
Hypothesis/Problem
To develop a risk assessment tool geared specifically towards the Union of European Football Associations (UEFA) Euro 2012.
Methods
In partnership with the Donetsk National Medical University, Donetsk Research and Development Institute of Traumatology and Orthopedics, Donetsk Regional Public Health Administration, and the Ministry of Emergency of Ukraine, a table-based tool was created, which, based on historical evidence, identifies relevant potential threats, evaluates their impacts and likelihoods on graded scales based on previous available data, identifies potential mitigating shortcomings, and recommends further mitigation measures.
Results
This risk assessment tool has been applied in the vulnerability-assessment-phase of the UEFA Euro 2012. Twenty-three sub-types of potential hazards were identified and analyzed. Ten specific hazards were recognized as likely to very likely to occur, including natural disasters, bombing and blast events, road traffic collisions, and disorderly conduct. Preventative measures, such as increased stadium security and zero tolerance for impaired driving, were recommended. Mitigating factors were suggested, including clear, incident-specific preparedness plans and enhanced inter-agency communication.
Conclusion
This hazard risk assessment tool is a simple aid in vulnerability assessment, essential for disaster preparedness and response, and may be applied broadly to future international events.

It is not known what constitutes the optimal emergency management system, nor is there a consensus on how effectiveness and efficiency in emergency response should be measured or evaluated. Literature on the role and tasks of commanders in the prehospital emergency services in the setting of mass-casualty incidents has not been summarized and published.
Problem
This comprehensive literature review addresses some of the needs for future research in emergency management through three research questions: (1) What are the basic assumptions underlying incident command systems (ICSs)? (2) What are the tasks of ambulance and medical commanders in the field? And (3) How can field commanders’ performances be measured and assessed?
Methods
A systematic literature search in MEDLINE, PubMed, PsycINFO, Embase, Cochrane Central Register of Controlled Trials, Cochrane Library, ISI Web of Science, Scopus, International Security & Counter Terrorism Reference Center, Current Controlled Trials, and PROSPERO covering January 1, 1990 through March 1, 2014 was conducted. Reference lists of included literature were hand searched. Included papers were analyzed using Framework synthesis.
Results
The literature search identified 6,049 unique records, of which, 76 articles and books where included in qualitative synthesis. Most ICSs are described commonly as hierarchical, bureaucratic, and based on military principles. These assumptions are contested strongly, as is the applicability of such systems. Linking of the chains of command in cooperating agencies is a basic difficulty. Incident command systems are flexible in the sense that the organization may be expanded as needed. Commanders may command by direction, by planning, or by influence. Commanders’ tasks may be summarized as: conducting scene assessment, developing an action plan, distributing resources, monitoring operations, and making decisions. There is considerable variation between authors in nomenclature and what tasks are included or highlighted. There are no widely acknowledged measurement tools of commanders’ performances, though several performance indicators have been suggested.
Conclusion
The competence and experience of the commanders, upon which an efficient ICS has to rely, cannot be compensated significantly by plans and procedures, or even by guidance from superior organizational elements such as coordination centers. This study finds that neither a certain system or structure, or a specific set of plans, are better than others, nor can it conclude what system prerequisites are necessary or sufficient for efficient incident management. Commanders need to be sure about their authority, responsibility, and the functional demands posed upon them.

The aim of this study was to shed light on damage to water supply facilities and the state of water resource operation at disaster base hospitals in Miyagi Prefecture (Japan) in the wake of the Great East Japan Earthquake (2011), in order to identify issues concerning the operational continuity of hospitals in the event of a disaster.
Methods
In addition to interview and written questionnaire surveys to 14 disaster base hospitals in Miyagi Prefecture, a number of key elements relating to the damage done to water supply facilities and the operation of water resources were identified from the chronological record of events following the Great East Japan Earthquake.
Results
Nine of the 14 hospitals experienced cuts to their water supplies, with a median value of three days (range = one to 20 days) for service recovery time. The hospitals that could utilize well water during the time that water supply was interrupted were able to obtain water in quantities similar to their normal volumes. Hospitals that could not use well water during the period of interruption, and hospitals whose water supply facilities were damaged, experienced significant disruption to dialysis, sterilization equipment, meal services, sanitation, and outpatient care services, though the extent of disruption varied considerably among hospitals. None of the hospitals had determined the amount of water used for different purposes during normal service or formulated a plan for allocation of limited water in the event of a disaster.
Conclusion
The present survey showed that it is possible to minimize the disruption and reduction of hospital functions in the event of a disaster by proper maintenance of water supply facilities and by ensuring alternative water resources, such as well water. It is also clear that it is desirable to conclude water supply agreements and formulate strategic water allocation plans in preparation for the eventuality of a long-term interruption to water services.

Medical records are a tenet of good medical practice and provide one method of communicating individual follow-up arrangements, informing research data, and documenting medical intervention.
Methods
The objective of this review was to look at one source (the published literature) of medical records used by foreign medical teams (FMTs) in sudden onset disasters (SODs). The published literature was searched systematically for evidence of what medical records have been used by FMTs in SODs.
Findings
The style and content of medical records kept by FMTs in SODs varied widely according to the published literature. Similarly, there was great variability in practice as to what happens to the record and/or the data from the record following its use during a patient encounter. However, there was a paucity of published work comprehensively detailing the exact content of records used.
Interpretation
Without standardization of the content of medical records kept by FMTs in SODs, it is difficult to ensure robust follow-up arrangements are documented. This may hinder communication between different FMTs and local medical teams (LMTs)/other FMTs who may then need to provide follow-up care for an individual. Furthermore, without a standard method of reporting data, there is an inaccurate picture of the work carried out. Therefore, there is not a solid evidence base for improving the quality of future response to SODs. Further research targeting FMTs and LMTs directly is essential to inform any development of an internationally agreed minimum data set (MDS), for both recording and reporting, in order that FMTs can reach the World Health Organization (WHO) standards for FMT practice.

This research aimed to learn from the experiences of leaders of well-developed, disaster preparedness-focused health care coalitions (HCCs), both the challenges and the successes, for the purposes of identifying common areas for improvement and sharing “promising practices.”
Hypothesis/Problem
Little data have been collected regarding the successes and challenges of disaster preparedness-focused HCCs in augmenting health care system preparedness for disasters.
Methods
Semi-structured interviews were conducted with a sample of nine HCC leaders. Transcripts were analyzed qualitatively.
Results
The commonly noted benefits of HCCs were: community-wide and regional partnership building, providing an impartial forum for capacity building, sharing of education and training opportunities, staff- and resource-sharing, incentivizing the participation of clinical partners in preparedness activities, better communication with the public, and the ability to surge. Frequently noted challenges included: stakeholder engagement, staffing, funding, rural needs, cross-border partnerships, education and training, and grant requirements. Promising practices addressed: stakeholder engagement, communicating value and purpose, simplifying processes, formalizing connections, and incentivizing participation.
Conclusions
Strengthening HCCs and their underlying systems could lead to improved national resilience to disasters. However, despite many successes, coalition leaders are faced with obstacles that may preclude optimal system functioning. Additional research could: provide further insight regarding the benefit of HCCs to local communities, uncover obstacles that prohibit local disaster-response capacity building, and identify opportunities for an improved system capacity to respond to, and recover from, disasters.

This study aimed to learn from the experiences of well-established, disaster preparedness-focused health care coalition (HCC) leaders for the purpose of identifying opportunities for improved delivery of disaster-health principles to health professionals involved in HCCs. This report describes current HCC education and training needs, challenges, and promising practices.
Methods
A semi-structured interview was conducted with a sample of leaders of nine preparedness-focused HCCs identified through a 3-stage purposive strategy. Transcripts were analyzed qualitatively.
Results
Training needs included: stakeholder engagement; economic sustainability; communication; coroner and mortuary services; chemical, biological, radiological, nuclear, and explosives (CBRNE); mass-casualty incidents; and exercise design. Of these identified training needs, stakeholder engagement, economic sustainability, and exercise design were relevant to leaders within HCCs, as opposed to general HCC membership. Challenges to education and training included a lack of time, little-to-no staff devoted to training, and difficulty getting coalition members to prioritize training. Promising practices to these challenges are also presented.
Conclusions
The success of mature coalitions in improving situational awareness, promoting planning, and enabling staff- and resource-sharing suggest the strengths and opportunities that are inherent within these organizations. However, offering effective education and training opportunities is a challenge in the absence of ubiquitous support, incentives, or requirements among health care professions. Notably, an online resource repository would help reduce the burden on individual coalitions by eliminating the need to continually develop learning opportunities.

On Tuesday, February 22, 2011, a 6.3 magnitude earthquake struck Christchurch, New Zealand. This qualitative study explored the intensive care units (ICUs) staff experiences and adopted leadership approaches to manage a large-scale crisis resulting from the city-wide disaster.
Problem
To date, there have been a very small number of research publications to provide a comprehensive overview of crisis leadership from the perspective of multi-level interactions among staff members in the acute clinical environment during the process of the crisis management.
Methods
The research was qualitative in nature. Participants were recruited into the study through purposive sampling. A semi-structured, audio-taped, personal interview method was chosen as a single data collection method for this study. This study employed thematic analysis.
Results
Formal team leadership refers to the actions undertaken by a team leader to ensure the needs and goals of the team are met. Three core, formal, crisis-leadership themes were identified: decision making, ability to remain calm, and effective communication. Informal leaders are those individuals who exert significant influence over other members in the group to which they belong, although no formal authority has been assigned to them. Four core, informal, crisis-leadership themes were identified: motivation to lead, autonomy, emotional leadership, and crisis as opportunity.
Shared leadership is a dynamic process among individuals in groups for which the objective is to lead one another to the achievement of group or organizational goals. Two core, shared-leadership themes were identified: shared leadership within formal medical and nursing leadership groups, and shared leadership between formal and informal leaders in the ICU.
Conclusion
The capabilities of formal leaders all contributed to the overall management of a crisis. Informal leaders are a very cohesive group of motivated people who can make a substantial contribution and improve overall team performance in a crisis. While in many ways the research on shared leadership in a crisis is still in its early stages of development, there are some clear benefits from adopting this leadership approach in the management of complex crises. This study may be useful to the development of competency-based training programs for formal leaders, process improvements in fostering and supporting informal leaders, and it makes important contributions to a growing body of research of shared and collective leadership in crisis.

Prehospital anaesthesia in the United Kingdom (UK) is provided by Helicopter Emergency Medical Service (HEMS) and British Association for Immediate Care (BASICS), a road-based service. Muscle relaxation in rapid sequence induction (RSI) has been traditionally undertaken with the use of suxamethonium; however, rocuronium at higher doses has comparable intubating conditions with fewer side effects.
Hypothesis/Problem
The aim of this survey was to establish how many prehospital services in the UK are now using rocuronium as first line in RSI.
Methods
An online survey was constructed identifying choice of first-line muscle relaxant for RSI and emailed to lead clinicians for BASICS and HEMS services across the UK. If rocuronium was used, further questions regarding optimal dose, sugammadex, contraindications, and difference in intubating conditions were asked.
Results
A total of 29 full responses (93.5%) were obtained from 31 services contacted. Suxamethonium was used first line by 17 prehospital services (58.6%) and rocuronium by 12 (41.4%). In 11 services (91.7%), a dose of 1 mg/kg of rocuronium was used, and in one service, 1.2 mg/kg (8.3%) was used. No services using rocuronium carried sugammadex. In five services, slower relaxation time was found using rocuronium (41.7%), and in seven services, no difference in intubation conditions were noted (58.3%). Contraindications to rocuronium use included high probability of difficult airway and anaphylaxis.
Conclusion
Use of rocuronium as first-line muscle relaxant in prehospital RSI is increasing. Continued auditing of practice will ascertain which services have adopted change and identify if complications of failed intubation increase as a result.

The most effective dose of prehospital furosemide in acute decompensated heart failure (ADHF) has not yet been identified and concerns of worsening renal function have limited its use.
Objective
To assess if administering high-dose furosemide is associated with worsening renal function.
Methods
The authors conducted a 2-center chart review for patients who presented via a single Emergency Medical Service (EMS) from June 5, 2009 through May 17, 2013. Inclusion criteria were shortness of breath, primarily coded as ADHF, and the administration of furosemide prior to emergency department (ED) arrival. A total of 331 charts were identified. The primary endpoint was an increase in creatinine (Cr) of more than 0.3 mg/dL from admission to any time during hospital stay. Exploratory endpoints included survival, length-of-stay (LOS), disposition, urine output in the ED, change in BUN/Cr from admission to discharge, and change in Cr from admission to 72 hours and discharge.
Results
When treated as a binary variable, there was no association observed between an increase in Cr of more than 0.3 mg/dL and prehospital furosemide dose. Baseline characteristics found to be associated with dose were included in the logistic regression model. Lowering the dose of prehospital furosemide was associated with higher odds of attaining a 0.3 mg/dL increase in Cr (adjusted OR = 1.49 for a 20 mg decrease; P = .019). There was no association found with any of the exploratory endpoints.
Conclusions
Patients who received higher doses of furosemide prehospitally were less likely to have an increase of greater than 0.3 mg/dL in Cr during the hospital course.

Disasters are high-stakes, low-frequency events. Telemedicine may offer a useful adjunct for paramedics performing disaster triage. The objective of this study was to determine the feasibility of telemedicine in disaster triage, and to determine whether telemedicine has an effect on the accuracy of triage or the time needed to perform triage.
Methods
This is a feasibility study in which an intervention team of two paramedics used the mobile device Google Glass (Google Inc; Mountain View, California USA) to communicate with an off-site physician disaster expert. The paramedic team triaged simulated disaster victims at the triennial drill of a commercial airport. The simulated victims had preassigned expected triage levels. The physician had an audio-video interface with the paramedic team and was able to observe the victims remotely. A control team of two paramedics performed disaster triage in the usual fashion. Both teams used the SMART Triage System (TSG Associates LLP; Halifax, England), which assigns patients into Red, Yellow, Green, and Black triage categories. The paramedics were video recorded, and their time required to triage was logged. It was determined whether the intervention team and the control team varied regarding accuracy of triage. Finally, the amount of time the intervention team needed to triage patients when telemedicine was used was compared to when that team did not use telemedicine.
Results
The two teams triaged the same 20 patients. There was no significant difference between the two groups in overall triage accuracy (85.7% for the intervention group vs 75.9% for the control group; P = .39). Two patients were triaged with telemedicine. For the intervention group, there was a significant difference in time to triage patients with telemedicine versus those without telemedicine (35.5 seconds; 95% CI, 72.5-143.5 vs 18.5 seconds; 95% CI, 13.4-23.6; P = .041).
Conclusion
There was no increase in triage accuracy when paramedics evaluating disaster victims used telemedicine, and telemedicine required more time than conventional triage. There are a number of obstacles to available technology that, if overcome, might improve the utility of telemedicine in disaster response.

Though many governmental and nongovernmental efforts for disaster prevention have been sought throughout Japan since the Great East Japan Earthquake on March 11, 2011, most of the preparation efforts for disasters have been based more on structural and conventionalized regulations than on scientific and objective grounds.
Problem
There has been a lack of scientific knowledge for space utilization for triage posts in disaster drill sessions. This report addresses how participants occupy and make use of the space within a triage post in terms of areas of use and occupied time.
Method
The trajectories of human movement by using Ubiquitous Stereo Vision (USV) cameras during two emergency drill sessions held in 2012 in a large commercial building have been measured. The USV cameras collect each participant's travel distance and the wait time before, during, and after undergoing triage. The correlation between the wait time and the space utilization of patients at a triage post has been analyzed.
Results
In the first session, there were some spaces not entirely used. This was caused largely by a patient who arrived earlier than others and lingered in the middle area, which caused the later arrivals to crowd the entrance area. On the other hand, in the second session, the area was used in a more evenly-distributed manner. This is mainly because the earlier arrivals were guided to the back space of the triage post (ie, the opposite side of the entrance), and the late arrivals were also guided to the front half, which was not occupied by anyone. As a result, the entire space was effectively utilized without crowding the entrance.
Conclusion
This study has shown that this system could measure people's arrival times and the speed of their movements at the triage post, as well as where they are placed until they receive triage. Space utilization can be improved by efficiently planning and controlling the positioning of arriving patients. Based on the results, it has been suggested that for triage operation, it is necessary to efficiently plan and control the placement of patients in order to use strategically limited spatial resources.
