In recent years, several authors have begun to address the medical and legal risks associated with patients refusing or being refused transport by emergency medical services (EMS) systems. However, data regarding patient outcomes still are lacking.

The purpose of this study was to determine: 1) why patients are not transported; and 2) the subsequent outcome of these patients.

A busy, suburban, volunteer EMS service with indirect medical control, but no guidelines for non-transport of patients.

A retrospective review of the records of 158 consecutive EMS incidents in which an ambulance was called, but the patient was not transported. Follow-up was attempted by telephone contact with the patient and/or family.

Telephone follow-up was established successfully for 93 cases (59%). Of the 93 patients, 60 (64.5%) subsequently sought care from a physician, 15 of whom (25%) later were admitted. The mean hospital stay was 6.6±7.9 days (median=3 days) with a range of 1–30 days. Two were admitted to an intensive care unit (ICU) and two others died. Of the 93 study cases, 43 (46%) involved situations in which the patient refused transport. Paramedics declined transport or mutually agreed not to transport in 50 cases (54%). This latter category accounted for 11 (73%) of the 15 hospitalizations. Ten percent of patients (or their families) stated that they were dissatisfied with the non-transport decisions.

Serious, even fatal outcomes were identified in the follow-up of patients not transported by EMS. Although a direct causal relationship was not established within the context of this study, situations in which EMS personnel either denied transport (or mutually agreed with the patient not to transport by ambulance) were twice as likely to result in hospitalization than were those cases in which the patients declined transportation against the advice of the EMS personnel.

To evaluate the effects of spinal immobilization on healthy participants.

A systematic review of randomized, controlled trials of spinal immobilization on healthy participants.

Seventeen randomized, controlled trials compared different types of immobilization devices, including collars, backboards, splints, and body strapping. For immobilization efficacy, collars, spine boards, vacuum splints, and abdominal/torso strapping provided a significant reduction in spinal movement. Adverse effects of spinal immobilization included a significant increase in respiratory effort, skin ischemia, pain, and discomfort.

Data from this review provide the best available evidence to support the well-recognized efficacy and potential adverse effects of spinal immobilization. However, comparisons of different immobilization strategies on trauma victims must be considered in order to establish an evidence base for this practice.

Mass-gathering events are dynamic and challenge traditional medical management systems. To improve the system for the provision of first aid at mass-gathering events, an evaluation of two models that assist in forecasting the number of patients presenting for first-aid services was conducted.

A prospective evaluation of a recurrent, mass-gathering event was undertaken comparing predicted patient presentations and ambulance transfers generated by a predictive model developed by Arbon et al and a retrospective review of seven years of historical, event data as described by Zeitz et al.

Patient presentation rate (per 1,000 patrons) for this event was 1.6 and the transport to hospital rate (per 1,000 patrons) was 0.07. The retrospective review closely predicted the actual overall attendance.Both methods forecast the number of patients presenting on a daily basis. The prediction proved to be more accurate, on a day-by-day basis, using the Zeitz method.

The Arbon method is particularly useful for events where there is no or limited information about previous medical work. Retrospective review of data generated from specific events (Zeitz method) considers the unique and individual variability that can occur from event to event and is more accurate at predicting patient presentations when the data are available. Both methods have the potential to be used more frequently to adequately and efficiently plan for the resources required for specific events.

Education and training are key elements of disaster management. Despite national and international educational programs in disaster management, there is no standardized curriculum available to guide the European Union (EU) member states. European- based Disaster Training Curriculum (DITAC), a multiple university-based project financially supported by the EU, is charged with developing a holistic and highly-structured curriculum and courses for responders and crisis managers at a strategic and tactical level. The purpose of this study is to qualitatively assess the prevailing preferences and characteristics of disaster management educational and training initiatives (ETIs) at a postgraduate level that currently exist in the EU countries.

An Internet-based qualitative search was conducted in 2012 to identify and analyze the current training programs in disaster management. The course characteristics were evaluated for curriculum, teaching methods, modality of delivery, target groups, and funding.

The literature search identified 140 ETIs, the majority (78%) located in United Kingdom, France, and Germany. Master level degrees were the primary certificates granted to graduates. Face-to-face education was the most common teaching method (84%). Approximately 80% of the training initiatives offered multi- and cross-disciplinary disaster management content. A competency-based approach to curriculum content was present in 61% of the programs. Emergency responders at the tactical level were the main target group. Almost all programs were self-funded.

Although ETIs currently exist, they are not broadly available in all 27 EU countries. Also, the curricula do not cover all key elements of disaster management in a standardized and competency-based structure. This study has identified the need to develop a standardized competency-based educational and training program for all European countries that will ensure the practice and policies that meet both the standards of care and the broader expectations for professionalization of the disaster and crisis workforce.

To investigate the relative distribution of hazards causing hospital evacuations, thereby to provide rudimentary risk information for hospital disaster planning.

Cases of hospital evacuations were retrieved from newspaper and publication databases and classified according to hazard type, proximate and original cause, duration, and casualties. Both partial and full evacuations were included. The total number of evacuation incidents for all hazards were compared to the total number of hospital incidents for the one hazard, fire, for which national data is available.

There were 275 reported evacuation incidents from 1971–1999, with an annual average of 21 in the 1990s, the period for which databases were more reliable. The most, 33, were recorded in 1994, the year of the Northridge Earthquake. Of all incidents, 63 (23%) were attributable primarily to internal fire, followed by internal hazardous materials (HazMat) events (18%), hurricane (14%), human threat (13%), earthquake (9%), external fire (6%), flood (6%), utility failure (5%), and external HazMat (4%).

More than 50% of the hospital evacuations occurred because of hazards originating in the hospital facility itself or from human intruders. While natural disasters were not the preponderant causes of evacuations, they caused severe problems when multiple hospitals in the same urban area were incapacitated simultaneously. Clearly, as hospitals are vulnerable to many hazards, mitigation investments should be assessed not in terms of single-hazard risk-cost-benefit analysis, but in terms of capacity to mitigate multiple hazards. In view of the many qualifications and limitations of the dataset used here, but value of such data for disaster planning, hospitals should be asked to submit standardized incident reports to permit national data gathering on major disruptions.

The number of paramedics in Israel is increasing. Despite this growth and important role, the emergency medical organizations lack information about the characteristics of their work.

The objective of this study was to examine the characteristics of the paramedics' work, the quality of their working lives, the factors that keep them in the profession, or conversely, draw them away from it.

Cross-sectional study conducted through telephone interviews of a random sample of 50% of the graduates of paramedic courses in Israel (excluding conscripted soldiers).

The factors that attract paramedics to the profession have much to do with the essence of the job—rescuing and saving—and a love of what it involves, as well as interest and variety. Pressures at work result from having to cope with a lack of administrative support, paperwork, long hours, imbalance between work and family life, and salary. They do not come from having to cope with responsibility, the pressure of working under uncertain conditions, and the sudden transition from calm situations to emergencies. Dissatisfaction at work is caused by burnout, work overload, and poor health. Physical and mental health that impedes their ability to work is related to a sense of burnout and the intention to change professions.

The findings about the relationships between health, job satisfaction, and burnout, coupled with the fact that within a decade, half of the currently employed paramedics will reach an age at which it is hard for them to perform their job, lead to the conclusion that there is a need to reconsider the optimum length of service in the profession. There also is a need to form organizational arrangements to change the work procedures of aging paramedics.

Considerable morbidity, mortality, and costs are associated with household emergency situations involving natural hazards and fires. Many households are poorly prepared for such emergency situations, and little is known about the psychosocial aspects of household emergency preparedness.

The aim of this study is to promote a better understanding of homeowners' experiences and perceptions regarding household emergency situations and related preparedness practices.

A brief survey was administered and three focus group sessions were conducted with homeowners (n = 16) from two metro Atlanta homeowners'associations.The survey inquired about basic demographic information, personal experience with a natural hazard or fire, and awareness of preparedness recommendations. The focus group discussions centered on household emergency preparedness perceptions and practices.

Participants defined household emergency preparedness as being able to survive with basic supplies (e.g., water, flashlights) for 48 hours or longer. While most participants had sufficient knowledge of how to prepare for household emergency situations, many did not feel fully prepared or had not completed some common preparedness measures. Concern about protecting family members and personal experience with emergency situations were identified as strong motivations for preparing the household for future emergencies.

The focus group findings indicate that most participants have prepared for household emergency situations by discussing the dangers with family members, stockpiling resources, and taking a CPR or first-aid class. However, to the extent that behavior is influenced, there is a gap between maintaining preparedness levels and internalizing preparedness recommendations. Prevention efforts in Georgia should focus on closing that gap.

Due to the fact that most high-rise structures (i.e., >75 feet high, or eight to ten stories) are constructed with extensive and redundant fire safety features, current fire safety procedures typically only involve limited evacuation during minor to moderate fire emergencies. Therefore, full-scale evacuation of high-rise buildings is highly unusual and consequently, little is known about how readily and rapidly high-rise structures can be evacuated fully. Factors that either facilitate or inhibit the evacuation process remain under-studied.

This paper presents results from the qualitative phase of the World Trade Center Evacuation Study, a three-year, five-phase study designed to improve our understanding of the individual, organizational, and environmental factors that helped or hindered evacuation from the World Trade Center (WTC) Towers 1 and 2, on 11 September 2001.

Qualitative data from semi-structured, in-depth interviews and focus groups involving WTC evacuees were collected and analyzed.

On the individual level, factors that affected evacuation included perception of risk (formed largely by sensory cues), preparedness training, degree of familiarity with the building, physical condition, health status, and footwear. Individual behavior also was affected by group behavior and leadership. At the organizational level, evacuation was affected by worksite preparedness planning, including the training and education of building occupants, and risk communication. The environmental conditions affecting evacuation included smoke, flames, debris, general condition and degree of crowdedness on staircases, and communication infrastructure systems (e.g., public address, landline, cellular and fire warden's telephones).

Various factors at the individual, organizational, and environmental levels were identified that affected evacuation. Interventions that address the barriers to evacuation may improve the full-scale evacuation of other high-rise buildings under extreme conditions. Further studies should focus on the development and evaluation of targeted interventions, including model emergency preparedness planning for high-rise occupancies.

This article characterizes the epidemiological outcomes, resource utilization, and time course of emergency needs in mass-casualty, terrorist bombings producing 30 or more casualties.

Eligible bombings were identified using a MEDLINE search of articles published between 1996 and October 2002 and a manual search of published references. Mortality, injury frequency, injury severity, emergency department (ED) utilization, hospital admission, and time interval data were abstracted and relevant rates were determined for each bombing. Median values for the rates and the inter-quartile ranges (IQR) were determined for bombing subgroups associated with: (1) vehicle delivery; (2) terrorist suicide; (3) confined-space setting; (4) open-air setting; (5) structural collapse sequela; and (6) structural fire sequela.

Inclusion criteria were met by 44 mass-casualty, terrorist bombings reported in 61 articles. Median values for the immediate mortality rates and IQRs were: vehicle-delivery, 4% (1–25%); terrorist-suicide, 19% (7–44%); confined-space 4% (1–11%); open-air, 1% (0–5%); structural-collapse, 18% (5–26%); structural fire 17% (1–17%); and overall, 3% (1–14%). A biphasic pattern of mortality and unique patterns of injury frequency were noted in all subgroups. Median values for the hospital admission rates and IQRs were: vehicle-delivery, 19% (14–50%); terrorist-suicide, 58% (38–77%); confined-space, 52% (36–71%); open-air, 13% (11–27%); structural-collapse, 41% (23–74%); structural-fire, 34% (25–44%); and overall, 34% (14–53%). The shortest reported time interval from detonation to the arrival of the first patient at an ED was five minutes. The shortest reported time interval from detonation to the arrival of the last patient at an ED was 15 minutes. The longest reported time interval from detonation to extrication of a live victim from a structural collapse was 36 hours.

Epidemiological outcomes and resource utilization in mass-casualty, terrorist bombings vary with the characteristics of the event.

To explore the determinants influencing oral/nasal endotracheal intubation (OETI/NETI) and determine which cognitive, therapeutic, and technical interventions may assist prehospital airway management.

Prospective review of run reports and structured interviews of paramedics involved in OETI/NETI attempts were conducted in a high-volume, inner-city, advanced life support (ALS) system during an eight-month period (July 1991 to February 1992). Data were abstracted from run reports, and paramedics were asked in structured interviews to describe difficulties in OETI/NETI attempts.

Of 236 patients studied, 88% (208) were intubated successfully. Success/failure rate was not related statistically to patients' ages (p = 0. 78), medical or trauma complaint (89% vs 85%, p = 0.35), oral versus nasal route (88% vs 85%, p = 0.38), care time (scene + transport times: success, 18 minutes; failure, 20 minutes, p = 0.30), paramedic seniority (p = 0.13), or number of attempts per paramedic (p >0.05). Increased level of consciousness (LOC) was associated with decreased success rate (p = 0.04). Paramedics reported difficulties in endotracheal intubation (ETI) attempts in 110 (46.6%) of patients. Factors reported to increase ETI difficulty were: 1) technical problems (35.6%); 2) mechanical problems (15.6%); and 3) combative patients (12.7%).

Oral endotracheal intubation and NETI success rates identified in this study are similar to those described in the literature, although innovative strategies could be used to facilitate prehospital airway management. Many of the factors found to increase ETI difficulty could be ameliorated by the administration of paralytic agents, that is, for combative patients. Focused training in cadaver and animal labs coupled with recurrence training in the operating suites should be used on a regular basis to decrease difficulties in visualization. Interventions directed at alleviating mechanical difficulties that should be explored include new-to-the-field techniques, such as retrograde intubation, fiber-optic technology, and surgical tracheal access.

Pediatric disaster medicine (PDM) triage is a vital skill set for pediatricians, and is a required component of residency training by the Accreditation Council for Graduate Medical Education (ACGME). Simulation training is an effective tool for preparing providers for high-stakes, low-frequency events. Debriefing is a learner-centered approach that affords reflection on one's performance, and increases the efficacy of simulation training. The purpose of this study was to measure the efficacy of a multiple-victim simulation in facilitating learners’ acquisition of pediatric disaster medicine (PDM) skills, including the JumpSTART triage algorithm. It was hypothesized that multiple patient simulations and a structured debriefing would improve triage performance.

A 10-victim school-shooting scenario was created. Victims were portrayed by adult volunteers, and by high- and low-fidelity simulation manikins that responded physiologically to airway maneuvers. Learners were pediatrics residents. Expected triage levels were not revealed. After a didactic session, learners completed the first simulation. Learners assigned triage levels to all victims, and recorded responses on a standardized form. A group structured debriefing followed the first simulation. The debriefing allowed learners to review the victims and discuss triage rationale. A new 10-victim trauma disaster scenario was presented one week later, and a third scenario was presented five months later. During the second and third scenarios, learners again assigned triage levels to multiple victims. Wilcoxon sign rank tests were used to compare pre- and post-test scores and performance on pre- and post-debriefing simulations.

A total of 53 learners completed the educational intervention. Initial mean triage performance was 6.9/10 patients accurately triaged (range = 5-10, SD = 1.3); one week after the structured debriefing, the mean triage performance improved to 8.0/10 patients (range = 5-10, SD = 1.37, P < .0001); five months later, there was maintenance of triage improvement, with a mean triage score of 7.8/10 patients (SD = 1.33, P < .0001).

Over-triage of an uninjured child with special health care needs (CSHCN) (67.8% of learners prior to debriefing, 49.0% one week post-debriefing, 26.2% five months post-debriefing) and under-triage of head-injured, unresponsive patients (41.2% of learners pre-debriefing, 37.5% post-debriefing, 11.0% five months post-debriefing) were the most common errors.

Structured debriefings are a key component of PDM simulation education, and resulted in improved triage accuracy; the improvement was maintained five months after the educational intervention. Future curricula should emphasize assessment of CSHCN and head-injured patients.

The New Injury Severity Score (NISS) was introduced in 1997 to improve outcome prediction based on anatomical severity scoring in trauma victims. Studies on populations of blunt trauma victims indicate that the NISS, predicts better than the Injury Severity Score (ISS) mortality post-injury, which is why the NISS has been recommended as the new “gold standard” for severity scoring. However, so far the accuracy of the NISS for penetrating injuries has not been validated against the ISS.

ISS and NISS scores were collected retrospectively for 1,787 war-and landmine victims in North Iraq. All victims only had penetrating injuries. The two tests were compared for prediction of short-term mortality and post-operative complications using Receiver Operating Characteristics (ROC) analysis.

Both the ISS and the NISS predicted mortality with high accuracy (ROC area under curve 0.9). There were no significant differences between the two tests. The predictive accuracy for post-operative complications was moderate for both tests (ROC-AUC <0.8), with the NISS performing significantly better than the ISS.

The NISS does not perform better than the ISS in penetrating injuries. However, this study was done on a low-risk trauma population, thus the results should not be extrapolated to high severity trauma. Due to statistical shortcomings in studies previously published, studies on far larger cohorts are necessary before the NISS should be adopted as the new “gold standard” for severity scoring.

Training emergency personnel on the clinical management of a mass-casualty incident (MCI) with prior chemical, biological, radioactive, nuclear, or explosives (CBRNE)-exposed patients is a component of hospital preparedness procedures.

The objective of this research was to determine whether a Virtual Emergency Department (VED), designed after the Stanford University Medical Center's Emergency Department (ED) and populated with 10 virtual patient victims who suffered from a dirty bomb blast (radiological) and 10 who suffered from exposure to a nerve toxin (chemical), is an effective clinical environment for training ED physicians and nurses for such MCIs.

Ten physicians with an average of four years of post-training experience, and 12 nurses with an average of 9.5 years of post-graduate experience at Stanford University Medical Center and San Mateo County Medical Center participated in this IRB-approved study. All individuals were provided electronic information about the clinical features of patients exposed to a nerve toxin or radioactive blast before the study date and an orientation to the “game” interface, including an opportunity to practice using it immediately prior to the study. An exit questionnaire was conducted using a Likert Scale test instrument.

Among these 22 trainees, two-thirds of whom had prior Code Triage (multiple casualty incident) training, and one-half had prior CBRNE training, about two-thirds felt immersed in the virtual world much or all of the time. Prior to the training, only four trainees (18%) were confident about managing CBRNE MCIs. After the training, 19 (86%) felt either “confident” or “very confident”, with 13 (59%) attributing this change to practicing in the virtual ED. Twenty-one (95%) of the trainees reported that the scenarios were useful for improving healthcare team skills training, the primary objective for creating them. Eighteen trainees (82%) believed that the cases also were instructive in learning about clinical skills management of such incidents. Conclusions: These data suggest that training healthcare teams in online, virtual environments with dynamic virtual patients is an effective method of training for management of MCIs, particularly for uncommonly occurring incidents.

These data suggest that training healthcare teams in online, virtual environments with dynamic virtual patients is an effective method of training for management of MCIs, particularly for uncommonly occurring incidents.

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.

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.

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).

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.

Understanding ambulance utilization patterns is essential to assessing prehospital system capacity and preparedness at the national level.

To describe the characteristics of patients transported to US emergency departments (EDs) by ambulance and to determine predictors of ambulance utilization.

Data were obtained from the National Hospital Ambulatory Medical Care Survey using mode of arrival, demographic and visit information, ICD-9-CM E and V-codes, and classified reasons for the visit.

The rates for ED visits of persons conveyed by ambulence were stable between 1997 and 2003, consisting of approximately one in every seven ED visits (14%). In 2003, there were 16.2 million ED visits for which an ambulance was used in the US. However, for patients with mental health visits, nearly one in three ED presentations (31%) arrived by ambulance. Significantly higher rates of ambulance use were associated with: (1) mental health visits; (2) older age; (3) African-Americans; (4) Medicare or self-pay insurance status; (5) urban ED location; (6) US regions outside of the South; (7) presentation between 12 midnight to 0800 hours; (8) injury-related visits; (9) urgent visit status; and/or (10) those resulting in hospital admission. Among mental health patients, older age, self-pay insurance status, urban ED location, regions outside the southern US, and urgent visit classification predicted ambulance use. Ambulance usage within the mental health group was highest for suicide and lowest for mood and anxiety disorder-related visits.

Reliance on ambulance services varies by age, insurance status, geographic factors, time of day, urgency of visit, subsequent admission status, and type of mental health disorder. Even after controlling for many confounding factors, mental health problems remain an important predictor of ambulance use.

Anecdotal observations about prehospital emergency medical care in major natural and human-made disasters, such as earthquakes, have suggested that some injured victims survive the initial impact, but eventually die because of a delay in the application of life-saving medical therapy.

A multidisciplinary, retrospective structured interview methodology to investigate injury risk factors, and causes and circumstances of prehospital death after major disasters was developed. In this study, a team of United States researchers and Costa Rican health officials conducted a survey of lay survivors and health care professionals who participated in the emergency medical response to the earthquake in Costa Rica on 22 April 1991.

Fifty-four deaths occurred prior to hospitatization (crude death rate = 0.4/1,000 population). Seventeen percent of these deaths (9/54) were of casualties who survived the initial impact but died at the scene or during transport. Twenty-two percent (2/9) were judged preventable if earlier emergency medical care had been available. Most injuries and deaths occurred in victims who were inside wooden buildings (p <.O1) as opposed to other building types or were pinned by rubble from building collapse. Autopsies performed on a sample of victims showed crush injury to be the predominant cause of death.

A substantial proportion of earthquake mortality in Costa Rica was protracted. Crush injury was the principal mechanism of injury and cause of death. The rapid institution of enhanced prehospital emergency medical services may be associated with a significant life- saving potential in these events.
