A substantial barrier to improving disaster preparedness in Australia is a lack of prescriptive national guidelines based on individual hospital capabilities. A recent literature review revealed that only one Australian hospital has published data regarding its current preparedness level.

To establish baseline levels of disaster knowledge, preparedness, and willingness to respond to a disaster among one hospital's staff, and thus enable the implementation of national disaster preparedness guidelines based on realistic capabilities of individual hospitals.

An anonymous questionnaire was distributed to individuals and departments that play key roles in the hospital's external disaster response. Questions concerned prior education and experience specific to disasters, general preparedness knowledge, perceived preparedness of themselves and their department, and willingness to respond to a disaster from a conventional and/or chemical, biological, or radiological incident.

Responses were received from 140 individuals representing nine hospital departments. Eighty-three participants (59.3%) had previously received disaster education; 53 (37.9%) had attended a disaster simulation drill, and 18 (12.9%) had responded to an actual disaster. The average disaster preparedness knowledge score was 3.57 out of 10. The majority of respondents rated themselves as “not really” prepared and were “unsure” of their respective departments’ level of preparedness. Most respondents indicated a willingness to participate in both a conventional incident involving burns and/or physical trauma, and an incident involving chemical, biological or radiological (CBR) weapons.

Australian hospital staff are under-prepared to respond to a disaster because of a lack of education, insufficient simulation exercises, and limited disaster experience. The absence of specific national standards and guidelines through which individual hospitals can develop their capabilities further compounds the poverty in preparedness.

To collate the opinions of experts and to reach consensus about the research priorities in the management of major incidents.

A three-round e-Delphi study was conducted using an international panel of experts drawn from active researchers and active educators in major incident management. General areas for consideration were derived from the literature analysis undertaken as part of the overall project.

Experts generated 221 statements in 11 topic areas in the first round. Fifty-one of these statements reached consensus in Round 2. A further 23 statements reached consensus in Round 3, leaving 147 statements that did not reach consensus.

An international expert panel reached consensus on 74 topics of research priority in major incidents management. The strongest themes within these topics were education and training, planning, and communication.

Mobile health (mHealth) technology can play a critical role in improving disaster victim tracking, triage, patient care, facility management, and theater-wide decision-making.

To date, no disaster mHealth application provides responders with adequate capabilities to function in an austere environment.

The Operational Medicine Institute (OMI) conducted a qualitative trial of a modified version of the off-the-shelf application iChart at the Fond Parisien Disaster Rescue Camp during the large-scale response to the January 12, 2010 earthquake in Haiti.

The iChart mHealth system created a patient log of 617 unique entries used by on-the-ground medical providers and field hospital administrators to facilitate provider triage, improve provider handoffs, and track vulnerable populations such as unaccompanied minors, pregnant women, traumatic orthopedic injuries and specified infectious diseases.

The trial demonstrated that even a non-disaster specific application with significant programmatic limitations was an improvement over existing patient tracking and facility management systems. A unified electronic medical record and patient tracking system would add significant value to first responder capabilities in the disaster response setting.

Knowing the pulse rate of a patient in a medical emergency can help to determine patient acuity and the level of medical care required. Little evidence exists regarding the ability of a 911 layperson-caller to accurately determine a conscious patient's pulse rate.

The hypothesis of this study was that, when instructed by a trained emergency medical dispatcher (EMD) using the scripted Medical Priority Dispatch System (MPDS) protocol Pulse Check Diagnostic Tool (PCDxT), a layperson-caller can detect a carotid pulse and accurately determine the pulse rate in a conscious person.

This non-randomized and non-controlled prospective study was conducted at three different public locations in the state of Utah (USA). A healthy, mock patient's pulse rate was obtained using an electrocardiogram (ECG) monitor. Layperson-callers, in turn, initiated a simulated 911 phone call to an EMD call-taker who provided instructions for determining the pulse rate of the patient. Layperson accuracy was assessed using correlations between the layperson-caller's finding and the ECG reading.

Two hundred sixty-eight layperson-callers participated; 248 (92.5%) found the pulse of the mock patient. There was a high correlation between pulse rates obtained using the ECG monitor and those found by the layperson-callers, overall (94.6%, P < .001), and by site, gender, and age.

Layperson-callers, when provided with expert, scripted instructions by a trained 911 dispatcher over the phone, can accurately determine the pulse rate of a conscious and healthy person. Improvements to the 911 instructions may further increase layperson accuracy.

India has been the focal point of various disasters, and has suffered considerable losses due to the same. Manpower shortage can impede disaster management; hence, including dental professionals in disaster management in India can be crucial.

To assess willingness to participate in disaster management among Indian dental graduates; to assess the objective knowledge, attitude, behavior and perceived knowledge regarding disaster management among Indian dental graduates.

All the interns in Manipal College of Dental Sciences, Mangalore, Karnataka were included in the present study. Their willingness to participate in disaster management and their objective knowledge, attitude, behavior and perceived knowledge related to disaster management were assessed using a questionnaire.

A total of 86 study subjects participated. A majority (98.8%) of respondents were willing to participate in disaster management. Mean objective knowledge, attitude, behavior and perceived knowledge scores were 48.65%, 80.26%, 29.85% and 60.80% respectively. Males reported higher perceived knowledge than females (P = .008), and respondents residing in hostels reported higher perceived knowledge than those not residing in hostels (P = .02). Gender showed significant correlations with attitude (r = 4.076, P = .044) and behavior (r = 3.722, P = .054), and residence with behavior of respondents (r = 5.690, P = .017).

A high degree of willingness to provide assistance during disasters was observed among undergraduate dental students. High attitude coupled with low knowledge and behavior scores regarding disaster management was also observed. Gender was associated with attitude and behavior, and residence with behavior of respondents regarding disaster management. Including disaster management in dental curricula and involvement of dental professionals in disaster management might be crucial for disaster management in India.

There has been limited research on the perspectives and needs of national caregivers when confronted with large-scale societal violence. In Iraq, although the security situation has improved from its nadir in 2006-2007, intermittent bombings, and other hostilities continue. National workers remain the primary health resource for the affected populace.

To assess the status and challenges of national physicians working in the Emergency Departments of an active conflict area.

This study was a survey of civilian Iraqi doctors working in Emergency Departments (EDs) across Iraq, via a convenience sample of physicians taking the International Medical Corps (IMC) Doctor Course in Emergency Medicine, given in Baghdad from December 2008 through August 2009.

The 148 physician respondents came from 11 provinces and over 50 hospitals in Iraq. They described cardiovascular disease, road traffic injuries, and blast and bullet injuries as the main causes of death and reasons for ED utilization. Eighty percent reported having been assaulted by a patient or their family member at least once within the last year; 38% reported they were threatened with a gun. Doctors reported seeing a median of 7.5 patients per hour, with only 19% indicating that their EDs had adequate physician staffing. Only 19% of respondents were aware of an established triage system for their hospital, and only a minority had taken courses covering ACLS- (16%) or ATLS-related (24%) material. Respondents reported a wide diversity of prior training, with only 3% having some type of specialized emergency medicine degree.

The results of this study describe some of the challenges faced by national health workers providing emergency care to a violence-stricken populace. Study findings demonstrate high levels of violent behavior directed toward doctors in Iraqi Emergency Departments, as well as staffing shortages and a lack of formal training in emergency medical care.

Estimating the number of ambulances needed in trauma-related Multiple Casualty Events (MCEs) is a challenging task.

Emergency medical services (EMS) regions in the United States have varying “best practices” for the required number of ambulances in MCE, none of which is based on metric criteria. The objective of this study was to estimate the number of ambulances required to respond to the scene of trauma-related MCE in order to initiate treatment and complete the transport of critical (T1) and moderate (T2) patients. The proposed model takes into consideration the different transport times and capacities of receiving hospitals, the time interval from injury occurrence, the number of patients per ambulance, and the pre-designated time frame allowed from injury until the transfer care of T1 and T2 patients.

The main theoretical framework for this model was based on prehospital time intervals described in the literature and used by EMS systems to evaluate operational and patient care issues. The North Atlantic Treaty Organization (NATO) triage categories (T1-T4) were used for simplicity.

The minimum number of ambulances required to respond to the scene of an MCE was modeled as being primarily dependent on the number of critical patients (T1) present at the scene any particular time. A robust quantitative model was also proposed to dynamically estimate the number of ambulances needed at any time during an MCE to treat, transport and transfer the care of T1 and T2 patients.

A new quantitative model for estimation of the number of ambulances needed during the prehospital response in trauma-related multiple casualty events has been proposed. Prospective studies of this model are needed to examine its validity and applicability.

Few studies have focused on the mental health consequences of indirect exposure to disasters caused by naturally occurring hazards. The present study assessed indirect exposure to the 2010 earthquake in Haiti among Haitian-Americans now living in Miami; these subjects had no direct exposure to the earthquake, but retained their cultural identity, language, and connection to family and friends in Haiti.

Two months following the earthquake a sample of Haitian-Americans was surveyed inquiring about: (1) their psychological reactions to the quake; (2) types of exposures experienced by their family members and friends in Haiti; and (3) symptom levels of (a) major depression, (b) generalized anxiety disorder, (c) complicated grief, (d) mental health status, and (e) physical health status.

Haitian-Americans living in Miami experienced a broad spectrum of indirect exposures to the 2010 earthquake in Haiti. These exposures were strongly associated with psychological distress, trauma-related mental health consequences, and diminished health status. Most notable was the multiplicity of indirect exposures to the on-scene experiences of multiple family members and friends in Haiti.

Consideration should be given to the psychological impact and needs for support among indirectly-exposed populations with strong affiliation to directly-impacted victims.

Road traffic injuries (RTIs) and attendant fatalities on Nigerian roads have been on an increasing trend over the past three decades. Mortality from RTIs in Nigeria is estimated to be 162 deaths/100,000 population. This study aims to compare and identify best prehospital trauma care practices in Nigeria and some other African countries where prehospital services operate.

A review of secondary data, grey literature, and pertinent published articles using a conceptual framework to assess: (1) policies; (2) structures; (3) first responders; (4) communication facilities; (5) transport and ambulance facilities, and (6) roadside emergency trauma units.

There is no national prehospital trauma care system (PTCS) in Nigeria. The lack of a national emergency health policy is a factor in this absence. The Nigerian Federal Road Safety Corps (FRSC) mainly has been responsible for prehospital services. South Africa, Zambia, Kenya, and Ghana have improved prehospital services in Africa.

Commercial drivers, laypersons, military, police, a centrally controlled communication network, and government ambulance services are feasible delivery models that can be incorporated into the Nigerian prehospital system. Prehospital trauma services have been useful in reducing morbidities and mortalities from traffic injuries, and appropriate implementation of this study's recommendations may reduce this burden in Nigeria.

Few emergency medical services (EMS) interventions in New Mexico have been assessed for efficacy, potential harm, or potential benefit. There is concern that many interventions added over the years may be outdated, harmful, or ineffective in the EMS setting. A formal process for reviewing the state EMS scope of practice using literature review and expert consensus is discussed. In Phase One of the project, interventions in the New Mexico EMS scope of practice were prioritized for further review by surveying a national cadre of EMS experts to evaluate EMS interventions using a utilitarian harm/benefit metric.

An electronic survey based on the 2010 New Mexico EMS Scope of Practice statute was administered from March through June, 2011. A national cadre of 104 respondents was identified. Respondents were either State EMS medical directors or EMS fellowship directors. Respondents were asked to rate the potential harm and the potential benefit of specific EMS interventions on a 5-point ordinal scale. Median harm and benefit scores were calculated.

A total of 88 completed surveys were received following 208 emailed invitations to 104 respondents (43% response rate). Twenty-two (22) highest-priority interventions (those with a harm/benefit median score ratio of >1) were identified. Seven additional second-priority interventions were also identified. These interventions will be advanced for formal literature review and expert consensus.

The New Mexico EMS Interventions Project offers a novel model for assessing a prehospital scope of practice.

Radioactive contamination can occur as a result of accidental or intentional release of radioactive materials (RM) into the environment. RM may deposit on clothing, skin, or hair. Decontamination of contaminated persons should be done as soon as possible to minimize the deleterious health effects of radiation. The goal of this study was to evaluate the decontamination efficiency (for residual contaminant) of the active components of “Shudhika,” an indigenously developed skin decontamination kit. The study kit is for external radioactive decontamination of intact skin.

Decontamination efficiency was evaluated on the skin surface of rabbit (n = 6) and human volunteers (n = 13). 99mTc sodium pertechnetate (200-250 μCi) was used as the radio-contaminant. Skin surface area (5 × 5 cm2) of thoracic abdominal region of the rabbit and the forearm and the palm of human volunteers were used for the study. Decontamination was performed by using cotton swabs soaked with chemical decontamination agents of the kit.

Decontamination efficiency (% of the contaminant removed) was calculated for each component of the study. Overall effectiveness of the kit was calculated to be 85% ± 5% in animal and 92% ± 3% in human skin surfaces. Running water and liquid soap with water was able to decontaminate volunteers' hand and animal skin up to 70% ± 5%. Chemical decontamination agents were applied only for trace residues (30% ± 5%). Efficiency of all the kit components was found up to be 20% ± 3% (animal) and 28% ± 2 (human), respectively. Residual contamination after final decontamination attempt for both the models was observed to be 12% ± 3% and 5% ± 2%. After 24 and 48 hours of the decontamination procedure, skin was found to be normal (no redness, erythema and edema were observed).

Decontaminants of the study kit were effective in removal of localized radioactive skin contamination when water is ineffective for further decontamination. By using the chemical decontaminants of the study kit, the use of water and radioactive waste generation could be reduced. Cross-contamination could also be avoided. During radiologic emergencies where water may be radioactively contaminated, the study kit could be used.

Substantial research demonstrates that the stressors accompanying the profession of paramedicine can lead to mental health concerns. In contrast, little is known about the effects of stress on paramedics’ ability to care for patients during stressful events. In this study, we examined paramedics’ acute stress responses and performance during simulated high-stress scenarios.

Twenty-two advanced care paramedics participated in simulated low-stress and high-stress clinical scenarios. The paramedics provided salivary cortisol samples and completed an anxiety questionnaire at baseline and following each scenario. Clinical performance was videotaped and scored on a checklist of specific actions and a global rating of performance. The paramedics also completed patient care documentation following each scenario.

The paramedics demonstrated greater increases in anxiety (P < .05) and salivary cortisol levels (P < .05) in response to the high-stress scenario compared to the low-stress scenario. Global rating scores were significantly lower in the high-stress scenario than in the low-stress scenario (P < .05). Checklist scores were not significantly different between the two scenarios (P = .12). There were more errors of commission (reporting information not present in the scenario) in the patient care documentation following the high-stress scenario than following the low-stress scenario (P < .05). In contrast, there were no differences in omission errors (failing to recall information present in the scenario) between the two scenarios (P = .34).

Clinical performance and documentation appear vulnerable to the impact of acute stress. This highlights the importance of developing systems and training interventions aimed at supporting and preparing emergency workers who face acute stressors as part of their every day work responsibilities.
