Standards for immobilizing potentially spine-injured patients in the prehospital environment are evolving. Current guidelines call for more research into treatment practices. Available research into spinal immobilization (SI) reveals a number of limitations.
Problem
There are currently few techniques for measuring head and neck motion that address identified limitations and can be adapted to clinically relevant scenarios. This study investigates one possible method.
Methods
Study participants were fitted with miniaturized accelerometers to record head motion. Participants were exposed to three levels of restraint: none, cervical-collar only, and full immobilization. In each condition, participants were instructed to move in single planes, with multiple iterations at each of four levels of effort. Participants were also instructed to move continuously in multiple planes, with iterations at each of three levels of simulated patient movement. Peak and average displacement and acceleration were calculated for each immobilization condition and level of effort. Comparisons were made with video-based measurement. Participant characteristics also were tracked.
Results
Acceleration and displacement of the head increased with effort and decreased with more restraint. In some conditions, participants generated measurable acceleration with minimal displacement. Continuous, multi-dimensional motions produced greater displacement and acceleration than single-plane motions under similar conditions.
Conclusion
Study results suggest a number of findings: acceleration complements displacement as a measure of motion in potentially spine-injured patients; participant effort has an effect on outcome measures; and continuous, multi-dimensional motion can produce results that differ from single-plane motions. Miniaturized accelerometers are a promising technology for future research to investigate these findings in realistic, clinically relevant scenarios.

The Syrian Arab Republic is entrenched in a deadly civil war, plunging the country into a state of chaos. With 3.2 million refugees abroad, 7.6 million internally displaced persons, and more than 200,000 killed, humanitarian assistance and international intervention are in dire need.
This report outlines the response to the Syrian humanitarian crisis by a South African-based nongovernmental organization (NGO). It describes the experiences of a health care worker, the patient profiles, and the lessons learned in a war zone.
Responding to a nation in need is of paramount importance. In order to maximize the benefit conferred, the team should always attempt to implement measures that leave a lasting legacy.

The Emergency Medical Services (EMS) approach to emergency prehospital care in the United States (US) has global influence. As the 50-year anniversary of modern US EMS approaches, there is value in examining US EMS education development over this period. This report describes US EMS education milestones and identifies themes that provide context to readers outside the US.
Method
As US EMS education is described mainly in publications of federal US EMS agencies and associations, a Google search and hand searching of documents identified publications in the public domain. MEDLINE and CINAHL Plus were searched for peer reviewed publications. Documents were reviewed using both a chronological and thematic approach.
Results
Seventy-eight documents and 685 articles were screened, the full texts of 175 were reviewed, and 41 were selected for full review. Four historical periods in US EMS education became apparent: EMS education development (1966-1980); EMS education consolidation and review (1981-1989); EMS education reflection and change (1990-1999); and EMS education for the future (2000-2014). Four major themes emerged: legislative authority, physician direction, quality, and development of the profession.
Conclusion
Documents produced through broad interprofessional consultations, with support from federal and US EMS authorities, reflect the catalysts for US EMS education development. The current model of US EMS education provides a structure to enhance educational quality into the future. Implementation evaluation of this model would be a valuable addition to the US EMS literature. The themes emerging from this review assist the understanding of the characteristics of US EMS education.

Communicable disease management (CDM) is an important component of disaster public health response operations. However, there is a lack of any performance assessment (PA) framework and related indicators for the PA. This study aimed to develop a PA framework and indicators in CDM in disasters.
Methods
In this study, a series of methods were used. First, a systematic literature review (SLR) was performed in order to extract the existing PA frameworks and indicators. Then, using a qualitative approach, some interviews with purposively selected experts were conducted and used in developing the PA framework and indicators. Finally, the analytical hierarchy process (AHP) was used for weighting of the developed indicators.
Results
The input, process, products, and outcomes (IPPO) framework was found to be an appropriate framework for CDM PA. Seven main functions were revealed to CDM during disasters. Forty PA indicators were developed for the four categories.
Conclusion
There is a lack of any existing PA framework in CDM in disasters. Thus, in this study, a PA framework (IPPO framework) was developed for the PA of CDM in disasters through a series of methods. It can be an appropriate framework and its indicators could measure the performance of CDM in disasters.

When disaster strikes, the number of patients requiring treatment can be overwhelming. In low-income countries, resources to assist the injured in a timely fashion may be limited. As a consequence, necrosis and wound infection in disaster patients is common and frequently leads to adverse health outcomes such as amputations, chronic wounds, and loss of life. In such compromised health care environments, low-tech and cheap wound care options are required that are in ready supply, easy to use, and have multiple therapeutic benefits. Maggot debridement therapy (MDT) is one such wound care option and may prove to be an invaluable tool in the treatment of wounds post-disaster.
Discussion
This report provides an overview of the wound burden experienced in various types of disaster, followed by a discussion of current treatment approaches, and the role MDT may play in the treatment of complex wounds in challenging health care conditions. Maggot debridement therapy removes necrotic and devitalized tissue, controls wound infection, and stimulates wound healing. These properties suggest that medicinal maggots could assist health care professionals in the debridement of disaster wounds, to control or prevent infection, and to prepare the wound bed for reconstructive surgery. Maggot debridement therapy-assisted wound care would be led by health care workers rather than physicians, which would allow the latter to focus on reconstructive and other surgical interventions. Moreover, MDT could provide a larger window for time-critical interventions, such as fasciotomies to treat compartment syndrome and amputations in case of life-threatening wound infection.
Recommendations
There are social, medical, and logistic hurdles to overcome before MDT can become widely available in disaster medical aid. Thus, research is needed to further demonstrate the utility of MDT in Disaster Medicine. There is also a need for reliable MDT logistics and supply chain networks. Integration with other disaster management activities will also be essential.
Conclusions
In the aftermath of disasters, MDT could play an important role facilitating timely and efficient medical treatment and improving patient outcomes. Existing social, medical, and logistic barriers will need to be overcome for MDT to be mainstreamed in Disaster Medicine.
The treatment of newborns in a disaster zone can be extremely challenging. The effects of the disaster combine with local health care disparity to give these neonates little chance of survival in the event of even minor complications. Rescue teams arriving at such locations must be prepared to handle and to aid these difficult situations using improvisation and ingenuity to overcome many of the unexpected hurdles. A discussion of the difficulties faced in the Philippines following a typhoon and recommendations for future teams are presented.

Minimal preparation time is a feature of responding to sudden onset disasters. While equipment and supplies are prepared for deployment at short notice, less is known of the physical preparation of medical responders. With many disaster-prone areas classified as tropical regions, there is potential for responders to endure a combination of high ambient temperatures and relative humidity during deployment. Heat acclimatization, defined as the physiological and perceptual adaptations to frequent elevations of core body temperature (Tc), is a key strategy to improve tolerance of hot conditions by medical responders.
Methods
Pre-deployment heat acclimatization guidelines were developed based upon the duration of physical training and the subjective rate of perceived exertion (session RPE). An objective of individual training sessions was the perception of body temperature as warm to hot. The guidelines were implemented for Team Bravo (2nd rotation) of the Australian Medical Assistance Team (AusMAT) deployed to Tacloban, Philippines following Typhoon Haiyan in November 2013. The guidelines were distributed electronically five to seven days prior to deployment and were followed by a consultation. A group training session in hot conditions was undertaken prior to departure.
Results
The AusMAT responders to utilize the guidelines were based in cool or temperate climates that required extra layers of clothing, training during warmer parts of the days, or warm indoor conditions to achieve session objectives. Responders reported the guidelines were simple to use, applicable to their varied training regimens, and had improved their confidence to work in the heat despite not completing the entire 14 day period.
Conclusion
The pre-deployment heat acclimatization guidelines provided AusMAT responders the ability to quantify their physical training and promoted physiological adaptations to maximize health, safety, and performance during deployment. While maintaining year-round heat acclimatization is considered essential for medical responders, these guidelines may facilitate beneficial adaptations once notified of deployment.
Paramedicine is experiencing significant growth in scope of practice, autonomy, and role in the health care system. Despite clinical governance models, the degree to which paramedicine ultimately can be safe and effective will be dependent on the individuals the profession deems suited to practice. This creates an imperative for those responsible for these decisions to ensure that assessments of paramedic competence are indeed accurate, trustworthy, and defensible.
Purpose
The purpose of this study was to explore and synthesize relevant theoretical foundations and literature informing best practices in performance-based assessment (PBA) of competence, as it might be applied to paramedicine, for design or evaluation of assessment programs.
Methods
A narrative review methodology was applied to focus intentionally, but broadly, on purpose relevant, theoretically derived research that could inform assessment protocols in paramedicine. Primary and secondary studies from a number of health professions that contributed to and informed best practices related to the assessment of paramedic clinical competence were included and synthesized.
Results
Multiple conceptual frameworks, psychometric requirements, and emerging lines of research are forwarded. Seventeen practice implications are derived to promote understanding as well as best practices and evaluation criteria for educators, employers, and/or licensing/certifying bodies when considering the assessment of paramedic competence.
Conclusions
The assessment of paramedic competence is a complex process requiring an understanding, appreciation for, and integration of conceptual and psychometric principles. The field of PBA is advancing rapidly with numerous opportunities for research.

The goal of this study was to test the hypothesis that the prehospital time between injury and arrival at a trauma center for critically injured children is associated with patient injury severity and mode of transport.
Methods
Secondary analysis of prospectively collected data on children 0-17 years of age admitted with traumatic injuries to a designated Level I pediatric trauma center from January 1, 2006 through September 30, 2007 was conducted. Multivariate regression methods were used to assess for factors independently associated with prehospital time.
Results
Of 1,175 admissions during the study period, only 355 (30%) had a prehospital time within 60 minutes of injury. Prehospital time within 60 minutes of injury was associated with higher frequency of coma, higher mean injury severity scores (ISS), and greater frequency of admission to the intensive care unit when compared with prehospital time beyond 60 minutes of injury. Children who arrived at the trauma center within 60 minutes versus beyond 60 minutes were 13-fold (odds ratio [OR]: 12.9; 95% Confidence Interval [CI], 7.6-22.0) more likely to be transported via air ambulance than a private vehicle, and had 4.8-fold greater odds (95% CI, 2.2-10.3) of transport via ground ambulance than private vehicle. For each kilometer of distance between the injury zip code and the trauma center, the odds of arrival within 60 minutes versus beyond 60 minutes decreased by 15% (OR: 0.85; 95% CI, 0.79-0.91).
Conclusion
Field triage and decision making appeared to correlate with severity of patient injury with expeditious transport of the most severely injured children to definitive trauma care. This finding serves as important groundwork that might enable further study into factors that influence triage and overall prehospital care for critically injured children.

Prehospital airway management (AM) is the first priority in the care of emergency and trauma victims as it has shown to improve survival in these patients.
Objective
The aim of this study was to assess training and knowledge of ambulance staff and availability of AM equipment in ambulances of Karachi, Pakistan.
Methods
This cross-sectional study was conducted from June through September 2014. Interviews were conducted with management of six ambulance service providers and 165 ambulance staff. Data from the management included availability of AM equipment in the ambulances, number and designation of staff sent for emergency calls, and AM training of staff. Ambulance staff were assessed for their awareness, knowledge, and training pertaining to AM.
Results
All the ambulance services (A through F) had basic equipment for AM but lacked qualified and trained staff. All services had solo drivers (98.3%) for emergency calls; however, Ambulance Service A also had doctors and paramedics. Only 35.7% (59/165) of ambulance staff had awareness regarding AM, out of which 77.9% (46/59) belonged to Ambulance Service A. Of these 59 staff, 81.4% received some form of AM training. Staff with AM awareness, when assessed for knowledge pertaining to AM steps and AM equipment, had a mean score of 4.7/5 and 8.4/12, respectively.
Conclusion
Even though ambulances are equipped with basic equipment, due to lack of trained staff, these ambulances only serve the mere purpose of transportation. There is a need to train ambulance staff and increase ambulance to staff ratio to improve prehospital AM and patient survival.

Each of the elements described in the Conceptual Framework for disasters has a temporal designation; each has a beginning and end time. The Temporal Framework defines these elements as phases that are based on characteristics rather than on absolute times. The six temporal phases include the: (1) Pre-event; (2) Event; (3) Structural Damage; (4) Functional Damage (changes in levels of functions of the Societal Systems); (5) Relief; and (6) Recovery phases. Development is not a phase of a disaster. The use of the Temporal Framework in studying and reporting disasters allows comparisons to be made between similar phases of different disasters, regardless of the hazard involved and/or the community impacted. For research and evaluation purposes, assessments, plans, and interventions must be described in relation to the appropriate temporal phase.

Studies of the health aspect of disasters focus either on the epidemiology of disasters to define the causes and the progression from a hazard to a disaster, or the evaluations of interventions provided during any phase of a disaster. Epidemiological disaster research studies are undertaken for the purposes of: (1) understanding the mechanisms by which hazards evolve into a disaster; (2) determining ways to mitigate the risk(s) that a specific hazard will progress into a disaster; (3) predicting the likely damages and needs of the population-at-risk for an event; and (4) identifying potential measures to increase the resilience of a community to future events. Epidemiological disaster research utilizes the Conceptual, Temporal, and Societal Frameworks to define what occurs when a hazard manifests as an event that causes a disaster. The findings from such studies should suggest interventions that could augment the absorbing, buffering, or/and response capacities to lessen the probability of similar damages occurring from the next event. Ultimately, the use of these Frameworks in studying the health aspects of a disaster will help define what to expect in a specific setting and the standards and best practices upon which education, training, competencies, performance, and professionalization will be built.

For the purposes of research and/or evaluation, a community/society is organized into 13 Societal Systems under the umbrella of an overall Coordination and Control System. This organization facilitates descriptions of a community/society or a component of a community for assessment at any designated time across the Temporal Phases of a disaster. Such assessments provide a picture of the functional status of one or more Systems that comprise a community. Since no system operates in isolation from the other systems, information of the concomitant status of several Societal Systems is crucial to gaining a complete understanding of compromised functions, as well as the effects and side effects of any intervention directed at restoring the functional state of the affected community or risk-reduction interventions of a community-at-risk. The 13 Societal Systems include: (1) Public Health; (2) Medical Care; (3) Water and Sanitation; (4) Shelter and Clothing; (5) Food and Nutrition; (6) Energy Supply; (7) Public Works and Engineering; (8) Social Structures; (9) Logistics and Transportation; (10) Security; (11) Communications; (12) Economy; and (13) Education. Many functions and sub-functions of the Systems overlap, or share some common sub-functions with other systems. For the purposes of research/evaluation, it is necessary to assign functions and sub-functions to only one of the Societal Systems.

More than 90% of traumatic morbidity and mortality occurs in low- and middle-income countries (LMIC). Haiti is the poorest country in the Western Hemisphere and lacks contemporary statistics on the epidemiology of traumatic injuries. This study aimed to characterize the burden of traumatic injuries among emergency department patients in the Northeast region of Haiti.
Methods
Data were collected from the emergency departments of all public hospitals in the Northeast region of Haiti, which included the Fort Liberté, Ouanaminthe, and Trou du Nord sites. All patients presenting for emergent care of traumatic injuries were included. Data were obtained via review of emergency department registries and patient records from October 1, 2013 through November 30, 2013. Data on demographics, mechanisms of trauma, and anatomical regions of injury were gathered using a standardized tool and analyzed using descriptive statistics. Temporal analysis of injury frequency was explored using regression modeling.
Results
Data from 383 patient encounters were accrued. Ouanaminthe Hospital treated the majority of emergent injuries (59.3%), followed by Fort Liberté (30.3%) and Trou du Nord (10.4%). The median age in years was 23 with 23.1% of patients being less than 15 years of age. Road traffic accidents (RTAs) and interpersonal violence accounted for 65.8% and 30.1% of all traumatic mechanisms, respectively. Extremity trauma was the most frequently observed anatomical region of injury (38.9%), followed by head and neck (30.3%) and facial (19.1%) injuries. Trauma due to RTA resulted in a single injury (83.8%) to either an extremity or the head and neck regions most frequently. A minority of patients had medical record documentation (37.9%). Blood pressure, respiratory rate, and mental status were documented in 19.3%, 4.1%, and 0.0% of records, respectively. There were 6.3 injuries/day during the data collection period with no correlation between the frequency of emergent trauma cases and day of the week (R^2=0.01).
Conclusions
Traumatic injuries are a common emergent presentation in the Northeast region of Haiti with characteristics similar to other LMIC. Documentation and associated data to adequately characterize the burden of disease in this region are lacking. Road traffic accidents are the predominate mechanism of injury, suggesting that interventions addressing prevention and treatment of this common occurrence may provide public health benefits in this setting.

With an increasing number of sicker patients, limited hospital beds, and an emphasis on day care, the profile of patients hospitalized to medicine wards has undergone a radical re-definition. The increasing share of patients hospitalized through the emergency department for acute care to medicine wards has left little space for hospitalization through the outpatient department (OPD). There are some global data available on the profile of patients presenting to the emergency rooms (ERs) and their subsequent outcome. Data from developing countries, especially India, in this regard are lacking.
Methods
This cross-sectional study included all patients hospitalized to the medicine ward through the medical emergency services, provided by the Department of Medicine, each Wednesday and every sixth Sunday for the entire year (a total of 62 days), from November 2010 through October 2011, and followed their outcome up to seven days after hospitalization.
Results
Of the 3,618 cases presenting to medicine emergency on these days, 1,547 (42.3%) were advised admission. Nine hundred sixty-seven reported to the medicine wards. One hundred eleven (7.73%) expired within 24 hours; others absconded, were lost in transit, did not consent to participation, or were discharged. During the next seven days, 452 (46.7%) recovered sufficiently and were discharged to go home. Two hundred thirty (23.8%) left the hospital without informing the medical staff. Fourteen (1.4%) patients were transferred to other departments. One hundred thirty-seven (8.8%) patients died during the next six days of hospitalization. After Multivariate Logistic Regression analysis, abnormal Glasgow Coma Scale (GCS) score, high systolic blood pressure (BP), age, increased total leucocyte count, increased globulin, low bicarbonate in arterial blood, low Mini Mental Status Examination (MMSE) score, and a raised urea >40 mg/dL were found to be associated significantly with mortality.
Conclusion
Of the 1,547 patients who needed urgent hospitalization, 248 (16%) died within the first week, one-half of them within the first 24 hours. An advanced age, abnormal GCS score, low MMSE score, increased systolic BP, leukocytosis, acidosis, and uremia were found to be associated with a fatal outcome. Therefore, nearly one-half of the patients who would have a fatal short-term outcome were likely to do so within the first 24 hours, making the first day of presentation “the golden day” period.

The aim of this study was to describe the most recent trends and epidemiologic patterns of fatal injuries resulting from explosions in Iraq, one of the countries most affected by violence from explosive devices.
Methods
Iraqi Ministry of Health (MoH) routine prospective injury surveillance collects information on all fatal injuries recorded by coroners from physical examinations, police reports, and family members in eight governorates of Iraq: Baghdad, Al-Anbar, Basrah, Erbil, Kerbala, Maysan, Ninevah, and Al-Sulaimaniya. This study analyzed explosive-related fatal injuries that occurred from January 1, 2010 through December 31, 2013.
Results
Analysis included 2,803 fatal injuries. The number of fatal injuries declined from 2010 through 2012, followed by an increase in 2013. One-thousand one-hundred and one explosion-related fatalities were documented in 2013, more than twice as many as in 2012 or in 2011. Most fatalities were among men aged 20-39 years. Of all causalities, 194 (6.9%) were among females and 302 (10.8%) were among children aged less than 18 years. The majority of fatalities were caused by improvised explosive devices (IEDs): car bombs (15.3%), suicide bombs (4.0%), and other IEDs (29.6%). The highest number of fatalities occurred in streets and roads. Of all deaths, 95.6% occurred in three governorates: Baghdad, Ninevah, and Al-Anbar.
Conclusions
Explosives continue to result in a high number of fatal injuries in Iraq. Following a period of declining violence from explosives, in 2013, fatalities increased. Most explosion-related injuries resulted from IEDs; males aged 20-39 years were at greatest risk.
