Road traffic crashes (RTCs) are common in Qatar, and are now considered the third leading cause of mortality. In this study, the safety devices used by the Qatari public at the time of RTCs were assessed and the association between seatbelt use by vehicle occupants involved in RTCs and severe injury/death in the prehospital setting was determined.
Methods:
This study was a retrospective case-control investigation. A Hamad Medical Corporation Emergency Medical Services (EMS) database of RTCs occurring from January 2006 to April 2007 was utilized for this study, providing a total of 5,267 patient records (83.5 % male, 16.5% female, median age = 28 years). Patient demographics, crash characteristics, prehospital assessments, and interventions were identified, and use of safety devices was determined. Univariate analysis including chi-square, Student's t-test, and analysis of variance (ANOVA) was performed as appropriate. “Case” patients are defined as those who had specific, critical prehospital assessments, or who received advanced cardio-respiratory life support measures in the field. Logistic regression modeling was used to predict the probability of a case being unbelted, controlling for confounders.
Results:
Seatbelt use in Qatar was low: 33.9% of males and 32.6% of females wore seatbelts at the time of the RTC. Victims involved in a vehicle rollover crash were less likely to be belted than were those involved in a non-rollover incident (26.2% belted vs. 37.8%; OR = 0.59; 95%CI = 0.50–0.68). Case patients—those with defined critical assessment findings or resuscitation in the field—and control patients were similar in age (30 years vs. 28 years median). Case patients were disproportionately male (89.1% vs. 83.2%; OR = 1.65; 95%CI = 1.01–2.83) and were more likely to be victims of a vehicle rollover crash (44.7% vs. 23.8%; OR = 2.57; 95%CI = 1.84–3.59). Seatbelt use was significantly lower among cases than controls: 19.7% of cases were reported to have worn seatbelts compared to 34.2% of controls (OR = 0.47; 95%CI = 0.31–0.69). This relationship also persisted (OR = 0.51; 95%CI = 0.33–0.76) after controlling for confounders.
Conclusions:
Seatbelt use in Qatar is low. Seatbelts are protective: in the pre-hospital setting unbelted vehicle occupants involved in RTCs were nearly twice as likely to suffer severe injury or death compared to belted patients. Prehospital morbidity and mortality appears to be reduced significantly by the consistent use of seatbelts by the motoring population in Qatar.
Research on skill acquisition and retention in the prehospital setting has focused primarily on resuscitation and defibrillation. Investigation into other first aid skills is required in order to validate practices and support training regimes. No studies have investigated competency using an extrication cervical collar for cervical spine immobilization.
Objective:
This study was conducted to confirm that a group of first responders could acquire and maintain competency in the application of an extrication cervical collar over a 12-month period.
Methods:
Participants attended a standardized training session that addressed the theory of application of an extrication cervical collar followed by hands-on practice. The training was presented by the same instructor and covered the nine key elements necessary in order to be deemed competent in extraction cervical collar application. Following the practical session, the competency of the participants was assessed. Participants were requested not to practice the skill during the 12-month period. Following the 12-month period, their skills were re-assessed by the same assessor.
Results:
Of the 64 subjects who participated in the study, 100% were competent after the initial first assessment. Forty-one participants (64%) were available for the second assessment (12 months later); of these, 25 (61%) maintained competence.
Conclusions:
Although the sample size was small, this research demonstrates that first responders are able to acquire competence in applying an extrication cervical collar. However, skill retention in the absence of usage or re-training is poor. Larger studies should be conducted to validate these results. In addition, there is a need for research on the clinical practice and outcomes associated with spinal immobilization in the prehospital setting.
Mapping risk and protective factors that may result in increased chances of survival or a decrease in injuries and fatalities in mass-casualty incidents (MCIs) is an important component in the process of emergency preparedness. While expert risk analyses are based on calculations of probability and damage, public estimates of risks more often are based on qualitative factors. It is important to understand how the public, and not just professional experts, perceive and react to the threat of MCIs whether they stem from natural causes or terrorism. Glenshaw et al provide valuable insight into the impressions and responses of a sample of individuals, both injured and uninjured who were involved in the Oklahoma City bombing. Their analysis helps us better understand what factors influenced the risk of injury to the individuals involved in the event. The main risk factor themes that emerged from the analysis included environmental glass, debris, and entrapment. Protective factors included knowledge of egress routes, shielding behaviors to deflect debris, and survival training. Building design and health status were reported as both risk and protective factors.
Due to several decades of armed conflict and civil unrest, Afghanistan is one of the countries most affected by landmines and unexploded ordnance worldwide.
Objective:
The study was performed to assess the magnitude of injuries due to landmines and unexploded ordnance in Afghanistan during 2002–2006 and to describe epidemiological patterns and potential risk factors for these events.
Methods:
Surveillance data including 5,471 injuries caused by landmines and unexploded ordnance in Afghanistan during 2002-2006 were analyzed. The International Committee of the Red Cross collects data on such injuries from 490 reporting health facilities and volunteers throughout the country. These surveillance data were used to describe injury trends, victim demographics, injury types, risk behaviors, and explosive types related to landmine and unexploded ordnance accidents.
Results:
The largest number of injuries (1,706) occurred in 2002. The number declined sharply to 1,049 injuries in 2003, and remained relatively stable with slight decline thereafter. Overall, 92% of victims were civilians, 91% were males, and 47% were children < 18 years of age. The case-fatality ratio was 17%. Approximately 50% of all injuries were caused by unexploded ordnance and 42% by landmines. Among children, 65% of injuries were caused by unexploded ordnance and only 27% by landmines, whereas in adults, most injuries (56%) were caused by landmines. The most common risk behaviors among children were tending animals, playing, and tampering with explosive devices. In adults, most common risk behaviors were traveling, performing activities of economic necessity, and tampering with explosives. Twenty-eight percent of the surviving victims who received mine awareness training and 2% of those who did not receive such training reported that the area where event occurred was marked.
Conclusions:
The large number of injuries and high proportion of child victims suggest that clearance and risk education activities fall short of achieving their goals, and must be substantially improved or expanded. Especially concerning is the high proportion of injuries caused by unexploded ordnance, and the high number of injuries sustained while tampering with explosive devices. Because unexploded ordnance is more visible than are landmines, and ordnance contaminated areas are cheaper to clear than are minefields, these injuries are highly preventable and should be a priority for clearance and risk education efforts.
Bombings, including the 1995 Oklahoma City bombing, remain an important public health threat. However, there has been little investigation into the impressions of injury risk or protective factors of bombing survivors.
Objective:
This study analyzes Oklahoma City bombing survivors' impressions of factors that influenced their risk of injury, and validates a hazard timeline outlining phases of injury risk in a building bombing.
Methods:
In-depth, semi-structured interviews were conducted within a sample of Oklahoma City bombing survivors. Participants included 15 injured and uninjured survivors, who were located in three buildings surrounding the detonation site during the attack.
Results:
Risk factor themes included environmental glass, debris, and entrapment. Protective factors included knowledge of egress routes, shielding behaviors to deflect debris, and survival training. Building design and health status were reported as risk and protective factors. The hazard timeline was a useful tool, but should be modified to include a lay rescue phase. The combination of a narrative approach and direct questioning is an effective method of gathering the perceptions of survivors.
Conclusions:
Investigating survivors' impressions of building bombing hazards is critical to capture injury exposures, behavior patterns, and decision-making processes during actual events, and to identify interventions that will be supported by survivors.
Public institutions such as governmental facilities, hospitals, universities, and amusement parks may be targeted by terrorists using weapons of mass destruction due to their potential to cause large numbers of casualties.
Consequentially, these institutions should be prepared to manage such an event by the development and implementation of specific preparedness guidelines for any conventional or unconventional terrorist attacks.
In order to test the preparedness of such an institution for a chemical event, a large-scale drill focusing on the first medical team to respond was conducted.
Some important lessons regarding the way the medical team operates and communicates were learned from this drill. Periodic drills should be performed in order to assess the practicality and applicability of these guidelines.
Increasingly, individuals are relying on the Internet as a major source of health information. When faced with sudden or pending disasters, people resort to the Internet in search of clear, current, and accurate instructions on how to prepare for and respond to such emergencies. Research about online health resources ascertained that information was written at the secondary education and college levels and extremely difficult for individuals with limited literacy to comprehend. This content analysis is the first to assess the reading difficulty level and format suitability of a large number of disaster and emergency preparedness Web pages intended for the general public.
Objectives:
The aims of this study were to: (1) assess the readability and suitability of disaster and emergency preparedness information on the Web; and (2) determine whether the reading difficulty level and suitability of online resources differ by the type of disaster or emergency and/or Website domain.
Methods:
Fifty Websites containing information on disaster and/or emergency preparedness were retrieved using the GoogleTM search engine. Readability testing was conducted on the first Web page, suggested by GoogleTM, addressing preparedness for the general public. The reading level was assessed using Flesch-Kincaid (F-K) and Flesch Reading Ease (FRE) measures. The Suitability Assessment of Materials (SAM) instrument was used to evaluate additional factors such as graphics, layout, and cultural appropriateness.
Results:
The mean F-K readability score of the 50 Websites was Grade 10.74 (95% CI = 9.93, 11.55). The mean FRE score was 45.74 (95% CI = 41.38, 50.10), a score considered “difficult”. A Web page with content about both risk and preparedness supplies was the most difficult to read according to F-K (Grade level = 12.1). Web pages with general disaster and emergency information and preparedness supplies were considered most difficult according to the FRE (38.58, 95% CI = 30.09, 47.08). The average SAM score was 48% or 0.48 (95% CI = 0.45, 0.51), implying below average suitability of these Websites. Websites on pandemics and bioterrorism were the most difficult to read (F-K: p = 0.012; FRE: p = 0.014) and least suitable (SAM: p = 0.035) compared with other disasters and emergencies.
Conclusions:
The results suggest the need for readily accessible preparedness resources on the Web that are easy-to-read and visually appropriate. Interdisciplinary collaborations between public health educators, risk communication specialists, and Web page creators and writers are recommended to ensure the development and dissemination of disaster and emergency resources that consider literacy abilities of the general public.
A common chief complaint to emergency dispatch communication centers worldwide is “breathing problems”. The chief complaint of breathing problems represents a wide spectrum of underlying diseases, patient conditions, and onset types. The current debate is on the potential ability of a dispatch protocol to safely and with high specificity, differentiate patients with minor or non-critical conditions from those conditions that pose risk to the patient and require advanced life support evaluation and care. This issue also has extended into the paramedic prehospital evaluation realm.
Objective:
The objective of this study was to describe the distribution of Medical Priority Dispatch System (MPDS) codes representing the spectrum of clinical descriptions within the breathing problems chief complaint and their associated outcomes, at the scene and during transport, as determined by [UK] paramedics.
Methods:
A retrospective, one-year study (September 2005 to August 2006) of a de-identified aggregate dataset from the London Ambulance Service (LAS) Trust was evaluated. A profile of the distribution of calls, incidents, patients, and outcomes (cardiac arrest [CA] and blue-in [BI] high acuity i.e., patients transported with lights and siren based on paramedic protocol) for the breathing problems chief complaint was evaluated.Odds ratios and 95% confidence intervals (CI) were used to quantify associations between the MPDS priority level's concurrent asthmatic conditions and outcomes. Two-sided Fisher's exact p-values were obtained to determine statistically significant associations, at a level of 0.05.
Results:
Sixteen percent (95,848/599,093) of all the patients were classified under the breathing problems chief complaint.Of these 95,848 patients,367 (0.38%) were CA outcomes, and 7.82% (n = 7,493) were BI outcomes.The Cardiac Arrest Quotient (i.e., the number of CA cases as a percentage of the number of patients) for the ECHO priority level was 46 times higher than was that of non-ECHO priority levels: DELTA and CHARLIE (17.05% vs. 0.37%). Asthmatics were associated with CA outcome (OR(95%CI): 0.60(0.47, 0.77), p <0.001), but not with BI outcome.
Conclusions:
The MPDS coding yielded a richer mix of severe outcomes in the higher priority levels. The Severe Respiratory Distress coding had the greatest number of patients and severe outcomes. Future studies that help refine the Severe Respiratory Distress code in the MPDS by more specific subgroups of patients would be beneficial.
Blood transfusion plays a critical role in the provision of medical care for disasters due to man-made and natural hazards. Although the short-term increase in blood donations following national disasters is well-documented, some aspects of blood transfusion during disasters remain under study. The 2003 earthquake in Bam, Iran resulted in the death of >29,000 people and injured 23,000. In total, 108,985 blood units were donated, but only 21,347 units (23%) actually were distributed to hospitals around the country. Kerman Province, the site of the disaster, received 1,231 (1.3%) of the donated units in the first four days after the disaster.The Bam experience revealed crucial missteps in the development of a post-event strategy for blood product management, and led to the development of a detailed disaster preparedness and response plan that addresses issues of donation, distribution, communication, transportation, and coordination. The current plan requires the Iranian Blood Transfusion Organization to convene a disaster task force immediately as the main coordinator of all disaster preparedness and response activities.
This is a descriptive report of the Swedish authorities' responses to the tsunami that affected Southeast Asia in December 2004. The main focus is the care of survivors and the injured during their transportation from Thailand and their return to Sweden. The psychological and physical after-effects also are presented based on a poll conducted one year after the tsunami.
This study utilizes a [US] national sample of emergency medical services (EMS) professionals to explore the hypothesis that demographic and work-related characteristics are associated with involvement in ambulance crashes.
Methods:
In 2004, a cohort of nationally registered EMS professionals was surveyed to determine ambulance crash involvement during a 12-month period. Involvement in an ambulance crash was the outcome variable of interest. Demographics such as age, community size, service type, call volume, time spent in an ambulance, and current sleep problems were analyzed as independent variables. A multivariate logistic regression model identified variables associated with involvement in an ambulance crash within the past year.
Results:
Surveys were received from 1,775/5,565 (32.0%) participants; 1,297 (73.1%) met the inclusion criteria. A total of 111 (8.6%) of participants reported being involved in an ambulance crash within the past 12 months. When controlling for call volume and time in an ambulance, the odds of involvement in an ambulance crash within the past year were significantly higher for younger EMS professionals and those reporting sleep problems.
Conclusions:
Results from this analysis suggest age and sleep problems are associated with involvement in an ambulance crash. Future studies should investigate interventions to minimize the effects of these associations.
Given the personal and societal costs associated with acute impairment and enduring post-traumatic stress disorder (PTSD), the mental health response to disasters is an integral component of disaster response planning. The purpose of this paper is to explore the compatibility between cognitive-behavioral psychology and the disaster mental health model, and explicate how cognitivebehavioral perspectives and intervention methods can enhance the effectiveness of disaster mental health services. It is argued that cognitive-behavioral methods, if matched to the contexts of the disaster and the needs of individuals, will improve efforts to prevent the development of PTSD and other trauma-related problems in survivors of disaster or terrorist events. First, the similarities between models of care underlying both disaster mental health services and cognitive-behavioral therapies are described. Second, examples of prior cognitive-behavioral therapy-informed work with persons exposed to disaster and terrorism are provided, potential cognitive-behavioral therapy applications to disaster and terrorism are explored, and implications of cognitive-behavioral therapy for common challenges in disaster mental health is discussed. Finally, steps that can be taken to integrate cognitive-behavioral therapy into disaster mental health are outlined. The aim is to prompt disaster mental health agencies and workers to consider using cognitive-behavioral therapy to improve services and training, and to motivate cognitive-behavioral researchers and practitioners to develop and support disaster mental health response.
The lack of disease-specific triage-management protocols that address the unique aspects of a pandemic places emergency medical services, and specifically, emergency medical services practitioners, at great risk.Without adequate protocols, the emergency health system will risk needless exposure, loss of functional capacity, and inappropriately triaged patients.This paper reports on the development of population-based triage-management protocols at two patient points of contact. The primary objective of the triage-management protocols is to identify patients infected by or exposed to the biological agent, and consequently, appropriately triage patients so as to optimize the utilization of emergency medical services and surge capacity resources through disposition and care at hospital-and non-hospital-based care facilities. Protocols must include standardized “flu questions”and a Fear and Resiliency Checklist to ensure protection and separation of the susceptible population from those infected or exposed.
Chronic diseases are major causes of death and disability and often require multiple prescribed medications for treatment and control. Public health emergencies (e.g., disasters due to natural hazards) that disrupt the availability or supply of these medications may exacerbate chronic disease or even cause death.
Problem:
A repository of chronic disease pharmaceuticals and medical supplies organized for rapid response in the event of a public health emergency is desirable. However, there is no science base for determining the contents of such a repository. This study provides the first step in an evidence-based approach to inform the planning, periodic review, and revision of repositories of chronic disease medications.
Methods:
Data from the 2004 National Hospital Ambulatory Medical Care Survey (NHAMCS) were used to examine the prescription medication needs of persons presenting to US hospital emergency departments for chronic disease exacerbations. It was assumed that the typical distribution of cases for an emergency department will reflect the patient population treated in the days after a public health emergency. The estimated numbers of prescribed drugs for chronic conditions that represent the five leading causes of death, the five leading primary diagnoses for physician office visits, and the five leading causes of disease burden assessed by disability-adjusted life years are presented.
Results:
The 2004 NHAMCS collected data on 36,589 patient visits that were provided by 376 emergency departments. Overall, the five drug classes mentioned most frequently for emergency department visits during 2004 were narcotic analgesics (30.7 million), non-steroidal anti-inflammatory drugs (25.2 million), non-narcotic analgesics (15.2 million), sedatives and hypnotics (10.4 million), and cephalosporins (8.2 million). The drug classes mentioned most frequently for chronic conditions were: (1) for heart disease, antianginal agents/vasodilators (715,000); (2) for cancer, narcotic analgesics (53,000); (3) for stroke, non-narcotic analgesics (138,000); (4) for chronic obstructive pulmonary disease, anti-asthmatics/bronchodilators (3.2 million); and (5) for diabetes, hypoglycemic agents (261,000). Ten medication categories were common across four or more chronic conditions.
Conclusions:
Persons with chronic diseases have an urgent need for ongoing care and medical support after public health emergencies. These findings provide one evidence-based approach for informing public health preparedness in terms of planning for and review of the prescription medication needs of clinically vulnerable populations with prevalent chronic disease.
The immediate impact of exposure to severe wounds, dead bodies, and immediate threat to life has been understudied. Most studies focus on the acute stress disorder and/or post-traumatic stress disorder phases in order to assess rescue personnel's symptomatology, and tend to neglect the immediate exposure to elements of the disaster.
Hypothesis:
Rescue personnel who had a history of previous exposure to dead bodies would exhibit higher levels of acute stress symptoms, dissociation, and depressive symptoms within the 24 hours following a traumatic event.
Methods:
Twenty-three rescue personnel participated in the search and excavation of dead and mutilated bodies following the Bet-Yehoshua train crash in Israel.The rescue personnel group was divided based on previous exposure to dead bodies. Each participant completed a demographic questionnaire, which included a question on perceived threat to life, the impact of event scale revised, the dissociative experience scale, and the center of epidemiologic studies depression questionnaire. Student's t-tests, along with multivariate analysis of covariance (MANCOVA) were conducted in order to learn which factors are related to psychiatric symptomatology following the immediate exposure to such stressors.
Results:
Among rescue personnel, those with previous exposure to dead bodies did not differ in their levels of acute stress symptoms, dissociation, and depressive symptoms from those who were not previously exposed to dead bodies.
Conclusions:
These results may suggest the possibility that the impact of exposure to dead bodies does not emerge in the acute stress reactions (ASR) phase (up to 24 hours after the event), but later when people have time to process the trauma. Another possibility is that the rescue coping mechanisms of detachment may serve as a buffer for the horrific sights encountered during the ASR period.
