Being one of Europe’s most densely populated countries, and having multiple nuclear installations, a heavy petrochemical industry, and terrorist targets, the Netherlands is at-risk for chemical, biological, or radionuclear (CBRN) incidents. Recent world and continental events show that this threat is real and that authorities may be underprepared.

The hypothesis of this study is that Dutch hospitals are underprepared to deal with these incidents.

A descriptive, cross-sectional study was performed. All 93 Dutch hospitals with an emergency department (ED) were sent a link to an online survey on different aspects of CBRN preparedness. Besides specific hospital information, information was obtained on the hospital’s disaster planning; risk perception; and availability of decontamination units, personal protective equipment (PPE), antidotes, radiation detection, infectiologists, isolation measures, and staff training.

Response rate was 67%. Sixty-two percent of participating hospitals were estimated to be at-risk for CBRN incidents. Only 40% had decontamination facilities and 32% had appropriate PPE available for triage and decontamination teams. Atropine was available in high doses in all hospitals, but specific antidotes that could be used for treating victims of CBRN incidents, such as hydroxycobolamine, thiosulphate, Prussian blue, Diethylenetriaminepentaacetic acid (DTPA), or pralidoxime, were less frequently available (74%, 65%, 18%, 14%, and 42%, respectively). Six percent of hospitals had radioactive detection equipment with an alarm function and 22.5% had a nuclear specialist available 24/7 in case of disasters. Infectiologists were continuously available in 60% of the hospitals. Collective isolation facilities were present in 15% of the hospitals.

There is a serious lack of hospital preparedness for CBRN incidents in The Netherlands.

Previous studies have illustrated pediatric knowledge deficits among Emergency Medical Services (EMS) providers. The purpose of this study was to identify perspectives of a diverse group of EMS providers regarding pediatric prehospital care educational deficits and proposed methods of training improvements.

Purposive sampling was used to recruit EMS providers in diverse settings for study participation. Two separate focus groups of EMS providers (administrative and non-administrative personnel) were held in three locations (urban, suburban, and rural). A professional moderator facilitated focus group discussion using a guide developed by the study team. A grounded theory approach was used to analyze data.

Forty-two participants provided data. Four major themes were identified: (1) suboptimal previous pediatric training and training gaps in continuing pediatric education; (2) opportunities for improved interactions with emergency department (ED) staff, including case-based feedback on patient care; (3) barriers to optimal pediatric prehospital care; and (4) proposed pediatric training improvements.

Focus groups identified four themes surrounding preparation of EMS personnel for providing care to pediatric patients. These themes can guide future educational interventions for EMS to improve pediatric prehospital care.

The increase in natural and man-made disasters occurring worldwide places Emergency Medicine (EM) physicians at the forefront of responding to these crises. Despite the growing interest in Disaster Medicine, it is unclear if resident training has been able to include these educational goals.

This study surveys EM residencies in the United States to assess the level of education in Disaster Medicine, to identify competencies least and most addressed, and to highlight effective educational models already in place.

The authors distributed an online survey of multiple-choice and free-response questions to EM residency Program Directors in the United States between February 7 and September 24, 2014. Questions assessed residency background and details on specific Disaster Medicine competencies addressed during training.

Out of 183 programs, 75 (41%) responded to the survey and completed all required questions. Almost all programs reported having some level of Disaster Medicine training in their residency. The most common Disaster Medicine educational competencies taught were patient triage and decontamination. The least commonly taught competencies were volunteer management, working with response teams, and special needs populations. The most commonly identified methods to teach Disaster Medicine were drills and lectures/seminars.

There are a variety of educational tools used to teach Disaster Medicine in EM residencies today, with a larger focus on the use of lectures and hospital drills. There is no indication of a uniform educational approach across all residencies. The results of this survey demonstrate an opportunity for the creation of a standardized model for resident education in Disaster Medicine.

Medical response to mass-casualty incidents (MCIs) requires specialized training and preparation. Basic Disaster Life Support (BDLS) is a course designed to prepare health care workers for a MCI. The purpose of this study was to evaluate the confidence of health care professionals in Thailand to face a MCI after participating in a BDLS course.

Basic Disaster Life Support was taught to health care professionals in Thailand in July 2008. Demographics and medical experience were recorded, and participants rated their confidence before and after the course using a five-point Likert scale in 11 pertinent MCI categories. Survey results were compiled and compared with P<.05 statistically significant.

A total of 162 health care professionals completed the BDLS course and surveys, including 78 physicians, 70 nurses, and 14 other health care professionals. Combined confidence increased among all participants (2.1 to 3.8; +1.7; P<.001). Each occupation scored confidence increases in each measured area (P<.001). Nurses had significantly lower pre-course confidence but greater confidence increase, while physicians had higher pre-course confidence but lower confidence increase. Active duty military also had lower pre-course confidence with significantly greater confidence increases, while previous disaster courses or experience increased pre-course confidence but lower increase in confidence. Age and work experience did not influence confidence.

Basic Disaster Life Support significantly improves confidence to respond to MCI situations, but nurses and active duty military benefit the most from the course. Future courses should focus on these groups to prepare for MCIs.

The Nepal earthquake of 2015 was a major disaster that exacted an enormous toll on human lives and caused extensive damage to the infrastructure of the region. Similar to other developing countries, Nepal has a network of community health workers (CHWs; known as female community health volunteers [FCHVs]) that was in place prior to the earthquake and continues to function to improve maternal and child health. These FCHVs and other community members were responsible, by default, for providing the first wave of assistance after the earthquake.

Community health workers such as FCHVs could be used to provide formal relief services in the event of an emergency, but there is a paucity of evidence-based literature on how to best utilize them in disaster risk reduction, preparedness, and response. Data are needed to further characterize the roles that this cadre has played in past disasters and what strategies can be implemented to better incorporate them into future emergency management.

In March 2016, key-informant interviews, FCHV interviews, and focus group discussions (FGDs) were conducted in Nepali health facilities using semi-structured guides. The audio-recorded data were obtained with the assistance of a translator (Nepali-English), transcribed verbatim in English, and coded by two independent researchers (manually and with NVivo 11 Pro software [QSR International; Melbourne, Australia]).

Across seven different regions, 14 interviews with FCHVs, two FGDs with community women, and three key-informant interviews were conducted. Four major themes emerged around the topic of FCHVs and the 2015 earthquake: (1) community care and rapport between FCHVs and local residents; (2) emergency response of FCHVs in the immediate aftermath of the earthquake; (3) training requested to improve the FCHVs’ ability to manage disasters; and (4) interaction with relief organizations and how to create collaborations that provide aid relief more effectively.

The FCHVs in Nepal provided multiple services to their communities in the aftermath of the earthquake, largely without any specific training or instruction. Proper preparation, in addition to improved collaboration with aid agencies, could increase the capacity of FCHVs to respond in the event of a future disaster. The information gained from this study of the FCHV experience in the Nepal earthquake could be used to inform risk reduction and emergency management policies for CHWs in various settings worldwide.

Maximum time-to-rescue has been studied accurately for many earthquakes in the years 1985-2004. No study is available for historical quakes.

This study aimed to evaluate long-term survivors (from the fifth day after the quake) of the Messina-Reggio Calabria earthquake (1908; Italy), which is considered, historically, to be the worst seismic event in Europe.

Accurate readings of 11 national newspapers from the fifth day after the quake looking for rescued persons and transferring, to an ad hoc form, all data relating to each rescued person.

The maximum time-to rescue was 20 days. There were 225 survivors, among them 51 children (22.6 %). For 23 out 225 rescued persons, there was evidence of availability of foods and drinkable fluids while under the rubble.

The maximum time-to-rescue under the debris following this historical earthquake far exceeds that of all other quakes that occurred in the years 1985-2004. The long survival under debris was probably due to the lack of an order to stop search and rescue. Recent strategies reducing the time for search and rescue carry the risk of missing survivors.

Specific knowledge and skills are required, especially in the first 72 hours post-disaster, to bridge the time gap until essential services are restored and Emergency Medical Services (EMS) can focus on individuals’ needs. This study explores disaster knowledge and preparedness in the first 72 hours as a function of the individual’s engagement in discussions about disasters, and several other factors (both at personal and community/country level), as well as the entities/organizations perceived by the individual as being responsible for disaster risk reduction (DRR) education.

A prospective, cross-sectional survey of 3,829 final-year high-school students was conducted in nine countries with different levels of disaster risk and economic development. Regression analyses examined the relationship between a 72-hour disaster preparedness composite outcome (ability to make water safe for drinking, knowledge of water potability, home evacuation skill, and improvising a safe room) and a series of independent predictors.

Respondents from countries with lower economic development were significantly better prepared for the first 72 hours post-disaster than those from developed countries (OR=767.45; CI=13.75-48,822.94; P=.001). While several independent predictors showed a significant main effect, combined disaster risk education (DRE) efforts, as a partnership between school and local government, had the best predictive value (OR=3.52; CI=1.48-8.41; P=.005).

Disaster preparedness in final-year high-school students is significantly better in developing countries. Further improvement requires a convergent effort in aligning the most effective educational policies and actions to best address the individual’s and the community needs.

Survival rates after out-of-hospital cardiac arrest (OHCA) vary considerably among regions. The chance of survival is increased significantly by lay rescuer cardiopulmonary resuscitation (CPR) before Emergency Medical Services (EMS) arrival. It is well known that for bystanders, reasons for not providing CPR when witnessing an OHCA incident may be fear and the feeling of being exposed to risk. The aim of this study was to gain a better understanding of why barriers to providing CPR are overcome.

Using a semi-structured interview guide, 10 lay rescuers were interviewed after participating in eight OHCA incidents. Qualitative content analysis was used. The lay rescuers were questioned about their CPR-knowledge, expectations, and reactions to the EMS and from others involved in the OHCA incident. They also were questioned about attitudes towards providing CPR in an OHCA incident in different contexts.

The lay rescuers reported that they were prepared to provide CPR to anybody, anywhere. Comprehending the severity in the OHCA incident, both trained and untrained lay rescuers provided CPR. They considered CPR provision to be the expected behavior of any community citizen and the EMS to act professionally and urgently. However, when asked to imagine an OHCA in an unclear setting, they revealed hesitation about providing CPR because of risk to their own safety.

Mutual trust between community citizens and towards social institutions may be reasons for overcoming barriers in providing CPR by lay rescuers. A normative obligation to act, regardless of CPR training and, importantly, without facing any adverse legal reactions, also seems to be an important factor behind CPR provision.

Following the recommendations of the World Association for Disaster and Emergency Medicine (WADEM; Madison, Wisconsin USA) to develop standards for training the undergraduates in disaster-relevant fields (2004), a German curriculum was approved in 2006. This paper aims to describe the level of training and interest of medical students nine years later.

The aim of this study was to assess the self-perception of medical students’ knowledge and interest in disaster medicine nine years after the implementation of a standardized disaster medicine curriculum in German medical schools.

This prospective, cross-sectional, observational study was conducted with medical students in Germany using a web-based, purpose-designed questionnaire consisting of 27 mandatory and 11 optional questions.

Nine hundred ninety-two students from 36 of 37 medical schools in Germany participated. More than one-half of medical students were aware of the field of disaster medicine. One hundred twenty-one students undertook training internally within their university and 307 undertook training externally at other institutions. Only a small content of the curriculum was taught. A difference in self-perception of knowledge between trained and untrained participants was found, despite the level of training being low in both groups. Participants were generally highly motivated to learn disaster medicine in a variety of institutions.

German students are still largely not well educated regarding disaster medicine, despite their high motivation. The curriculum of 2006 was not implemented as originally planned and the number of trained students still remains low as the self-perception of knowledge. Currently, there is no clear and standardized training concept in place. A renewal in the agreement of implementation of the curriculum at medical schools should be targeted in order to follow the recommendation of WADEM.

The frequency of disasters is increasing around the world with more people being at risk. There is a moral imperative to improve the way in which disaster evaluations are undertaken and reported with the aim of reducing preventable mortality and morbidity in future events. Disasters are complex events and undertaking disaster evaluations is a specialized area of study at an international level.

While some frameworks have been developed to support consistent disaster research and evaluation, they lack validation, consistent terminology, and standards for reporting across the different phases of a disaster. There is yet to be an agreed, comprehensive framework to structure disaster evaluation typologies.

The aim of this paper is to outline an evolving comprehensive framework for disaster evaluation typologies. It is anticipated that this new framework will facilitate an agreement on identifying, structuring, and relating the various evaluations found in the disaster setting with a view to better understand the process, outcomes, and impacts of the effectiveness and efficiency of interventions.

Research was undertaken in two phases: (1) a scoping literature review (peer-reviewed and “grey literature”) was undertaken to identify current evaluation frameworks and typologies used in the disaster setting; and (2) a structure was developed that included the range of typologies identified in Phase One and suggests possible relationships in the disaster setting.

No core, unifying framework to structure disaster evaluation and research was identified in the literature. The authors propose a “Comprehensive Framework for Disaster Evaluation Typologies” that identifies, structures, and suggests relationships for the various typologies detected.

The proposed Comprehensive Framework for Disaster Evaluation Typologies outlines the different typologies of disaster evaluations that were identified in this study and brings them together into a single framework. This unique, unifying framework has relevance at an international level and is expected to benefit the disaster, humanitarian, and development sectors. The next step is to undertake a validation process that will include international leaders with experience in evaluation, in general, and disasters specifically. This work promotes an environment for constructive dialogue on evaluations in the disaster setting to strengthen the evidence base for interventions across the disaster spectrum. It remains a work in progress.

Research suggests Emergency Medical Services (EMS) over-use in urban cities is partly due to substance users with limited access to medical/social services. Recent efforts to deliver brief, motivational messages to encourage these individuals to enter treatment have not considered EMS providers.

Little research has been done with EMS providers who serve substance-using patients. The EMS providers were interviewed about participating in a pilot program where they would be trained to screen their patients for substance abuse and encourage them to enter drug treatment.

Qualitative interviews were conducted with Baltimore City Fire Department (BCFD; Baltimore, Maryland USA) EMS providers (N=22). Topics included EMS misuse, work demands, and views on participating in the pilot program. Interviews were transcribed and analyzed using grounded theory and constant-comparison.

Participants were mostly white (68.1%); male (68.2%); with Advanced Life Skills training (90.9%). Mean age was 37.5 years. Providers described the “frequent flyer problem” (eg, EMS over-use by a few repeat non-emergent cases). Providers expressed disappointment with local health delivery due to resource limitations and being excluded from decision making within their administration, leading to reduced team morale and burnout. Nonetheless, providers acknowledged they are well-positioned to intervene with substance-using patients because they are in direct contact and have built rapport with them. They noted patients might be most receptive to motivational messages immediately after overdose revival, which several called “hitting their bottom.” Several stated that involvement with the proposed study would be facilitated by direct incorporation into EMS providers’ current workflow. Many recommended that research team members accompany EMS providers while on-call to observe their day-to-day work. Barriers identified by the providers included time constraints to intervene, limited knowledge of substance abuse treatment modalities, and fearing negative repercussions from supervisors and/or patients. Despite reservations, several EMS providers expressed inclination to deliver brief motivational messages to encourage substance-using patients to consider treatment, given adequate training and skill-building.

Emergency Medical Service providers may have many demands, including difficult case time/resource limitations. Even so, participants recognized their unique position as first responders to deliver motivational, harm-reduction messages to substance-using patients during transport. With incentivized training, implementing this program could be life- and cost-saving, improving emergency and behavioral health services. Findings will inform future efforts to connect substance users with drug treatment, potentially reducing EMS over-use in Baltimore.

Continuous positive airway pressure (CPAP) improves outcomes in patients with respiratory distress. Additional benefits are seen with CPAP application in the prehospital setting. Theoretical safety concerns regarding Basic Life Support (BLS) providers using CPAP exist. In Delaware’s (USA) two-tiered Emergency Medical Service (EMS) system, BLS often arrives before Advanced Life Support (ALS).

This study fills a gap in literature by evaluating the safety of CPAP applied by BLS prior to ALS arrival.

This was a retrospective, observational study using Quality Assurance (QA) data collected from October 2009 through December 2012 throughout a state BLS CPAP pilot program; CPAP training was provided to BLS providers prior to participation. Collected data include pulse-oximetry (spO2), respiratory rate (RR), heart rate (HR), skin color, and Glasgow Coma Score (GCS) before and after CPAP application. Pre-CPAP and post-CPAP values were compared using McNemar’s and t-tests. Advanced practitioners evaluated whether CPAP was correctly applied and monitored and whether the patient condition was “improved,” “unchanged,” or “worsened.”

Seventy-four patients received CPAP by BLS; CPAP was correctly indicated and applied for all 74 patients. Respiratory status and CPAP were appropriately monitored and documented in the majority of cases (98.6%). A total of 89.2% of patients improved and 4.1% worsened; CPAP significantly reduced the proportion of patients with SpO2<92%, RR>24, and cyanosis (P<.01). The GCS improved from mean (standard deviation [SD]) 13.9 (SD=1.9) to 14.1 (SD=1.9) after CPAP (mean difference [MD]=0.17; 95% CI, -0.49 to 0.83; P=.59). The HR decreased from 115.7 (SD=53) to 105.1 (SD=37) after CPAP (MD=-10.9; 95% CI, -3.2 to -18.6; P<.01). The SpO2 increased from 80.8% (SD=11.4) to 96.9% (SD=4.2) after CPAP (MD=17.8; 95% CI, 14.2-21.5; P<.01).

The BLS providers were able to determine patients for whom CPAP was indicated, to apply it correctly, and to appropriately monitor the status of these patients. The majority of patients who received CPAP by BLS providers had improvement in their clinical status and vital signs. The findings suggest that CPAP can be safely used by BLS providers with appropriate training.

The evaluation tool was first derived from the formerly Consortium of British Humanitarian Agencies’ (CBHA; United Kingdom), now “Start Network’s,” Core Humanitarian Competency Framework and formatted in an electronic data capture tool that allowed for offline evaluation. During a 3-day humanitarian simulation event, participants in teams of eight to 10 were evaluated individually at multiple injects by trained evaluators. Participants were assessed on five competencies and a global rating scale. Participants evaluated both themselves and their team members using the same tool at the end of the simulation exercise (SimEx).

All participants (63) were evaluated. A total of 1,008 individual evaluations were completed. There were 90 (9.0%) missing evaluations. All 63 participants also evaluated themselves and each of their teammates using the same tool. Self-evaluation scores were significantly lower than peer-evaluations, which were significantly lower than evaluators’ assessments. Participants with a medical degree, and those with humanitarian work experience of one month or more, scored significantly higher on all competencies assessed by evaluators compared to other participants. Participants with prior humanitarian experience scored higher on competencies regarding operating safely and working effectively as a team member.

This study presents a novel electronic evaluation tool to assess individual performance in five of six globally recognized humanitarian competency domains in a 3-day humanitarian SimEx. The evaluation tool provides a standardized approach to the assessment of humanitarian competencies that cannot be evaluated through knowledge-based testing in a classroom setting. When combined with testing knowledge-based competencies, this presents an approach to a comprehensive competency-based assessment that provides an objective measurement of competency with respect to the competencies listed in the Framework. There is an opportunity to advance the use of this tool in future humanitarian training exercises and potentially in real time, in the field. This could impact the efficiency and effectiveness of humanitarian operations.

Makkah (Mecca) is a holy city located in the western region of the Kingdom of Saudi Arabia. Each year, millions of pilgrims visit Makkah. These numbers impact both routine health care delivery and disaster response. This study aimed to evaluate hospitals’ disaster plans in the city of Makkah.

Study investigators administered a questionnaire survey to 17 hospitals in the city of Makkah. Data on hospital characteristics and three key domains of disaster plans (general evaluation of disaster planning, structural feasibility of the hospitals, and health care worker knowledge and training) were collated and analyzed.

A response rate of 82% (n=14) was attained. Ten (71%) of the hospitals were government hospitals, whereas four were private hospitals. Eleven (79%) hospitals had a capacity of less than 300 beds.

Only nine (64%) hospitals reviewed their disaster plan within the preceding two years. Nine (64%) respondents were drilling for disasters at least twice per year. The majority of hospitals did not rely on a hazard vulnerability analysis (HVA) to develop their Emergency Operations Plan. Eleven (79%) hospitals had the Hospital Incident Command Systems (HICS) present in their plans.

All hospitals described availability of some supplies required for the first 24 hours of a disaster response, such as: N95 masks, antidotes for nerve agents, and antiviral medications. Only five (36%) hospitals had a designated decontamination area. Nine (64%) hospitals reported ability to re-designate inpatient wards into an intensive care unit (ICU) format. Only seven (50%) respondents had a protocol for increasing availability of isolation rooms to prevent the spread of airborne infection. Ten (71%) hospitals had a designated disaster-training program for health care workers.

Makkah has experienced multiple disaster incidents over the last decade. The present research suggests that Makkah hospitals are insufficiently prepared for potential future disasters. This may represent a considerable threat to the health of both residents and visitors to Makkah. This study demonstrated that there is significant room for improvement in most aspects of hospital Emergency Operations Plans, in particular: reviewing the plan and increasing the frequency of multi-agency and multi-hospital drills. Preparedness for terrorism utilizing chemical, biologic, radiation, nuclear, explosion (CBRNE) and infectious diseases was found to be sub-optimal and should be assessed further.

Effective ventilation during cardiopulmonary resuscitation (CPR) is essential to reduce morbidity and mortality rates in cardiac arrest. Hyperventilation during CPR reduces the efficiency of compressions and coronary perfusion.

How could ventilation in CPR be optimized? The objective of this study was to evaluate non-invasive ventilator support using different devices.

The study compares the regularity and intensity of non-invasive ventilation during simulated, conventional CPR and ventilatory support using three distinct ventilation devices: a standard manual resuscitator, with and without airway pressure manometer, and an automatic transport ventilator. Student’s t-test was used to evaluate statistical differences between groups. P values <.05 were regarded as significant.

Peak inspiratory pressure during ventilatory support and CPR was significantly increased in the group with manual resuscitator without manometer when compared with the manual resuscitator with manometer support (MS) group or automatic ventilator (AV) group.

The study recommends for ventilatory support the use of a manual resuscitator equipped with MS or AVs, due to the risk of reduction in coronary perfusion pressure and iatrogenic thoracic injury during hyperventilation found using manual resuscitator without manometer.

In 2015, the authors reported the results of a preliminary investigation of preventable disaster deaths (PDDs) at medical institutions in areas affected by the Great East Japan Earthquake (2011). This initial survey considered only disaster base hospitals (DBHs) and hospitals that had experienced at least 20 patient deaths in Miyagi Prefecture (Japan); therefore, hospitals that experienced fewer than 20 patient deaths were not investigated. This was an additional study to the previous survey to better reflect PDD at hospitals across the entire prefecture.

Of the 147 hospitals in Miyagi Prefecture, the 14 DBHs and 82 non-DBHs that agreed to participate were included in an on-site survey. A database was created based on the medical records of 1,243 patient deaths that occurred between March 11, 2011 and April 1, 2011, followed by determination of their status as PDDs.

A total of 125 cases of PDD were identified among the patients surveyed. The rate of PDD was significantly higher at coastal hospitals than inland hospitals (17.3% versus 6.3%; P<.001). Preventable disaster deaths in non-DBHs were most numerous in facilities with few general beds, especially among patients hospitalized before the disaster in hospitals with fewer than 100 beds. Categorized by area, the most frequent causes of PDD were: insufficient medical resources, disrupted lifelines, delayed medical intervention, and deteriorated environmental conditions in homes and emergency shelters in coastal areas; and were delayed medical intervention and disrupted lifelines in inland areas. Categorized by hospital function, the most frequent causes were: delayed medical intervention, deteriorated environmental conditions in homes and emergency shelters, and insufficient medical resources at DBHs; while those at non-DBHs were disrupted lifelines, insufficient medical resources, delayed medical intervention, and lack of capacity for transport within the area.

Preventable disaster death at medical institutions in areas affected by the Great East Japan Earthquake occurred mainly at coastal hospitals with insufficient medical resources, disrupted lifelines, delayed medical intervention, and deteriorated environmental conditions in homes and emergency shelters constituting the main contributing factors. Preventing PDD, in addition to strengthening organizational support and functional enhancement of DBHs, calls for the development of business continuity plans (BCPs) for medical facilities in directly affected areas, including non-DBHs.

Previous studies have found that older adults are more likely to use Emergency Medical Services (EMS) than younger adults, but the reasons for this remain understudied.

This study aimed to determine if older age is associated with using EMS for transportation to an emergency department (ED) after controlling for confounding variables.

A cross-sectional survey study was conducted at a large academic medical center. Data on previous medical history, chief complaint, self-perceived illness severity, demographic information, and mode of arrival to the ED were collected on all subjects. Those who arrived to the ED via EMS also were asked reasons why they opted to call an ambulance for their illness/injury. Descriptive statistics were used to quantify survey responses, and multivariable regression was used to assess the independent effect of age on mode of ED arrival.

Data from 1,058 subjects were analyzed, 449 (42%) of whom arrived to the ED via EMS. Compared to adults<55 years, the unadjusted prevalence ratio for the association between age and EMS use was 1.18 (95% CI, 0.96-1.45) for subjects 55-79 years and 1.54 (95% CI, 1.18-2.02) for subjects ≥80 years. After adjustment for confounding variables, age remained a statistically significant risk factor for EMS use (P<.05).

Older age is an independent risk factor for transportation to the ED via ambulance; however, this effect is attenuated by number of chronic medical conditions and history of depression. Additional research is needed to account for confounders unmeasured in this study and to elucidate reasons for the increased frequency of EMS use among older adults.

Examining various problems in the aftermath of disasters is very important to the disaster victims. Managing and coordinating food supply and its distribution among the victims is one of the most important problems after an earthquake. Therefore, the purpose of this study was to recognize problems and experiences in the field of nutritional aiding during an earthquake.

This qualitative study was of phenomenological type. Using the purposive sampling method, 10 people who had experienced nutritional aiding during the Bam Earthquake (Iran; 2003) were interviewed. Colaizzi’s method of analysis was used to analyze interview data.

The findings of this study identified four main categories and 19 sub-categories concerning challenges in the nutritional aiding during the Bam Earthquake. The main topics included managerial, aiding, infrastructural, and administrative problems.

The major problems in nutritional aiding include lack of prediction and development of a specific program of suitable nutritional pattern and nutritional assessment of the victims in critical conditions. Forming specialized teams, educating team members about nutrition, and making use of experts’ knowledge are the most important steps to resolve these problems in the critical conditions; these measures are the duties of the relevant authorities.
