The 13th World Congress on Disaster and Emergency Medicine, convened in Melbourne, Australia in May 2003, requested the World Association for Disaster and Emergency Medicine (WADEM) to lead the development of “International Standards and Guidelines on Education and Training for “Disaster Medicine”. This Paper has been developed by a Working Group of the WADEM Education Committee (“the Working Group”) in response to that request from the international “Disaster Medicine” and emergency health community. The main focus of the Working Group is to develop standards and guidelines for education and training in the multi-disciplinary health response to major events that threaten the health status of a community. The contemporary view is that of a multi-disciplinary health response to major events which threaten the health status of a community, including the prevention and mitigation of future events, and taking account of the broader context in which these events occur.
It is the vision of the Working Group that evidence-based standards and guidelines for education and training must be developed in a broad sense, for all members of the healthcare community. Rather than purely describing isolated performance indicators, the Working Group agreed that priority be given to explaining the general approach, presenting the conceptual framework, clarifying important principles, and describing the educational needs and training requirements for situations for which there exist a major threat to the health status of a community.
It is not the intent to produce an updated educational curriculum for special courses in “Disaster Medicine” by listing levels of theoretical knowledge and clinical skills required for medical doctors, nurses, and paramedics. Nor, does the Working Group think it is useful to repeat requirements and learning outcomes that are part of the normal basic education and training for the various health professionals.
The purpose of this Issues Paper is to present an initial summary of current issues relating to an international perspective of “Disaster Medicine” education and training. This summary has been prepared following discussions within the Working Group of the WADEM Education Committee. The paper aims to stimulate debate and form the basis of further of discussion at an international meeting scheduled to be held in Brussels (Belgium) on 29–31 October 2004.
The Working Group has structured this Issues Paper into five parts and has identified several key issues for discussion.
Part 1: Understanding the contemporary interpretation of the multi-disciplinary health response to major events that threaten the health status of a community
Issue 1: Definitions and terminology in “Disaster Medicine”;
Issue 2: Getting to grips with the contemporary concepts and international trends in “Disaster Medicine”; and,
Issue 3: Valuing personal attributes in “Disaster Medicine” practitioners.
Part 2: Developing an underlying scientific framework for linking theory to practice in “Disaster Medicine”
Issue 4: Creating a scientific framework(s) for “Disaster Medicine”.
Part 3: Defining a conceptual framework and general principals to develop “International Standards and Guidelines on Education and Training for the Multi-disciplinary Health Response to Major Events that Threaten the Health Status of a Community”
Issue 5: Where are we now? Getting to grips with the contemporary concepts and international trends in “Disaster Medicine” education and training.
Issue 6: Where do we want to get to? Identifying contemporary, evidence-based education and training standards and guidelines for “Disaster Medicine” education and training programs.
Issue 7: How do we get there? Overcoming barriers to introducing the International Standards and Guidelines.
Part 4: Maintaining the momentum—improving international collaboration
Issue 8: Exploring the feasibility of an ongoing, international, collaborative network of “Centres of Excellence” in “Disaster Medicine” research and/or education.
Part 5: Additional input
Issue 9: What other issues would you like to bring to the attention of the Working Group?
Conclusions:
The results of the consultation will lead to the development of international standards and guidelines that will be presented and consensus sought during the 14th World Congress on Disaster and Emergency Medicine (WCDEM-14) to be convened in Edinburgh in May, 2005.
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.
Hypothesis/Problem
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.
Methods
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.
Results
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).
Conclusion
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.

Advanced Automatic Collision Notification (AACN) services in passenger vehicles capture crash data during collisions that could be transferred to Emergency Medical Services (EMS) providers. This study explored how EMS response times and other crash factors impacted the odds of fatality. The goal was to determine if information transmitted by AACN could help decrease mortality by allowing EMS providers to be better prepared upon arrival at the scene of a collision.
Methods
The Crash Injury Research and Engineering Network (CIREN) database of the US Department of Transportation/National Highway Traffic Safety Administration (USDOT/NHTSA; Washington DC, USA) was searched for all fatal crashes between 1996 and 2012. The CIREN database also was searched for illustrative cases. The NHTSA’s Fatal Analysis Reporting System (FARS) and National Automotive Sampling System Crashworthiness Data System (NASS CDS) databases were queried for all fatal crashes between 2000 and 2011 that involved a passenger vehicle. Detailed EMS time data were divided into prehospital time segments and analyzed descriptively as well as via multiple logistic regression models.
Results
The CIREN data showed that longer times from the collision to notification of EMS providers were associated with more frequent invasive interventions within the first three hours of hospital admission and more transfers from a regional hospital to a trauma center. The NASS CDS and FARS data showed that rural collisions with crash-notification times >30 minutes were more likely to be fatal than collisions with similar crash-notification times occurring in urban environments. The majority of a patient’s prehospital time occurred between the arrival of EMS providers on-scene and arrival at a hospital. The need for extrication increased the on-scene time segment as well as total prehospital time.
Conclusion
An AACN may help decrease mortality following a motor vehicle collision (MVC) by alerting EMS providers earlier and helping them discern when specialized equipment will be necessary in order to quickly extricate patients from the collision site and facilitate expeditious transfer to an appropriate hospital or trauma center.

Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition. This information would help to predict factors affecting patient treatment and disposition to guide ongoing training of first responders and to evaluate the appropriateness of staffing skills mix at future events.
Hypothesis
Patient demographics, environmental factors, and attendance would influence the nature and severity of presentations at the SRES, which would influence staffing requirements.
Methods
A retrospective analysis of 4,141 patient record forms was performed for patients who presented to St John Ambulance (Australian Capital Territory, Australia) at the SRES between 2012 and 2014 inclusive. Presentation type was classified using a previously published minimum data set. Data on weather and crowd size were obtained from the Australian Bureau of Meteorology (Melbourne, Victoria, Australia) and the SRES, respectively. Statistical analyses were performed using SPSS v22 (IBM; Armonk, New York USA).
Results
Between 2012 to 2014, over 2.5 million people attended the SRES with 4,141 patients treated onsite. As expected, the majority of presentations were injuries (49%) and illnesses (46%). Although patient demographics and presentation types did not change over time, the duration of treatment increased. A higher proportion of patients were discharged to hospital or home compared to the proportion of patients discharged back to the event. Patients from rural/regional locations (accounting for 15% of all patients) were more likely to require advanced treatment, health professional review, and were more likely to be discharged to hospital or home rather than discharged back to the event. Extremes of temperature were associated with a lower crowd size and higher patient presentation rate (PPR), but had no impact on transfer or referral rates to hospital.
Conclusion
This study demonstrated that analyses of patient presentations at an agricultural show provide unique insights on weather, attendance, and demographic features that correlated with treatment and disposition. These data can help guide organizers with information on how to better staff and train health care providers at future mass-gathering events of this type.

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.
Methods
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.
Results
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).
Conclusions
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.

Disasters present unique challenges for teams providing medical assistance to those populations impacted by the event. This scoping review focused on the characteristics of medical teams in disaster and how these characteristics are developed. The scoping review methods of Arksey and O’Malley were followed. An inductive thematic analysis of selected articles was used to identify recurrent themes. A total of 6,521 articles were reviewed from eight databases, yielding 33 articles. Four recurrent theme groups were identified: (1) adaptability, flexibility, and improvisation; (2) creativity and innovation; (3) experience and training; and (4) leadership and command structure. The study highlighted key characteristics identified by responders for effective team functioning and interdependence between the characteristics. It also identified the paucity of literature on the subject. Results from the study can help to guide future research and training development for medical teams in disaster.

The aim of this study was to explore physical and mental consequences and injury mechanisms among bus crash survivors to identify aspects that influence recovery.
Methods
The study participants were the total population of survivors (N=56) from a bus crash in Sweden. The study had a mixed-methods design that provided quantitative and qualitative data on injuries, mental well-being, and experiences. Results from descriptive statistics and qualitative thematic analysis were interpreted and integrated in a mixed-methods analysis.
Results
Among the survivors, 11 passengers (20%) sustained moderate to severe injuries, and the remaining 45 (80%) had minor or no physical injuries. Two-thirds of the survivors screened for posttraumatic stress disorder (PTSD) risk were assessed, during the period of one to three months after the bus crash, as not being at-risk, and the remaining one-third were at-risk. The thematic analysis resulted in themes covering the consequences and varying aspects that affected the survivors’ recoveries. The integrated findings are in the form of four “core cases” of survivors who represent a combination of characteristics: injury severity, mental well-being, social context, and other aspects hindering and facilitating recovery. Core case Avery represents a survivor who had minor or no injuries and who demonstrated a successful mental recovery. Core case Blair represents a survivor with moderate to severe injuries who experienced a successful mental recovery. Core case Casey represents a survivor who sustained minor injuries or no injuries in the crash but who was at-risk of developing PTSD. Core case Daryl represents a survivor who was at-risk of developing PTSD and who also sustained moderate to severe injuries in the crash.
Conclusion
The present study provides a multi-faceted understanding of mass-casualty incident (MCI) survivors (ie, having minor injuries does not always correspond to minimal risk for PTSD and moderate to severe injuries do not always correspond to increased risk for PTSD). Injury mitigation measures (eg, safer roadside material and anti-lacerative windows) would reduce the consequences of bus crashes. A well-educated rescue team and a compassionate and competent social environment will facilitate recovery.

Earthquake-related trauma results in crush injuries and bony- and soft-tissue trauma. There are no systematic reviews analyzing the typical injury patterns and treatments in “Mega-Mass-Casualty” earthquakes. The characterization of an injury pattern specific to disaster type, be it natural or manmade, is imperative to build an effective disaster preparedness and response system.
Methods
The systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A comprehensive search strategy was developed to identify all publications relating to earthquakes and the orthopedic treatment in adult patients. The following databases were searched: PubMed (Medline; US National Library of Medicine, National Institutes of Health; Bethesda, Maryland USA), Ovid (Ovid Technologies; New York, New York USA), Web of Science (Thomson Reuters; New York, New York USA), and The Cochrane Library (The Cochrane Collaboration; Oxford, United Kingdom).
Results
The searches identified 4,704 articles: 4,445 after duplicates were removed. The papers were screened for title and abstract and 65 out of those were selected for full-text analysis. The quality of data does not permit a standard-of-care (SOC) to be defined. Scarcity and poor quality of the data collected also may suggest a low level of accountability of the activity of the international hospital teams. Qualitatively, it is possible to define that there are more open fractures during daytime hours than at night. Excluding data about open and closed fractures, for all types of injuries, the results underline that the higher the impact of the earthquake, as measured by Richter Magnitude Scale (RMS), the higher is the number of injuries.
Discussion
Regarding orthopedic injuries during earthquakes, special attention must be paid to the management of the lower limbs most frequently injured. Spinal cord involvement following spine fractures is an important issue: this underlines how a neurosurgeon on a disaster team could be an important asset during the response. Conservative treatment for fractures, when possible, should be encouraged in a disaster setting. Regarding amputation, it is important to underline how the response and the quality of health care delivered is different from one team to another. This study shows how important it is to improve, and to require, the accountability of international disaster teams in terms of type and quality of health care delivered, and to standardize the data collection.

Paramedics respond to emergency scenes in often uncontrolled settings without being aware of potential risks. This makes paramedicine one of the most dangerous occupations. One of these dangers is the risk of contracting infectious diseases. Research in this area is predominantly focused on compliance in the use of protective equipment, attitudes and perceptions of paramedics, infectious disease policy, and exposure rates to blood and body fluids. The purpose of this scoping review was to determine what is known about the impact of infectious disease on the health of paramedics.
Methods
Using the Arskey and O’Malley methodological framework, a scoping review was undertaken, which allows for a broad search of the available evidence.
Results
The literature search identified eight articles for review that reported on paramedic exposure trends; the lack of reported blood-borne infections contracted, such as hepatitis B, hepatitis C, and human immunodeficiency virus (HIV); instances of severe acute respiratory syndrome (SARS) infections; and the higher prevalence of methicillin-resistant staphylococcus aureus (MRSA) nasal infections amongst paramedics.
Conclusions
Exposure to infectious diseases is decreasing, yet it remains significant. The decrease is attributed to prevention strategies; however, paramedic knowledge and attitudes as well as the uncontrolled environment paramedics work in can be a barrier. Contraction of infectious diseases is generally low; exceptions to this are MRSA colonization, influenza, and SARS. Paramedics are at greater risk of acquiring these infectious diseases compared to the general public. The effect on the health of paramedics is not well reported.

The benefits of emergency lights and sirens (L&S) use as warning devices by ambulances continue to be a debated topic in Emergency Medical Services (EMS). While the most widely studied aspect of L&S use has been related to their effect on ambulance response and transport times, the literature suggests minimal time savings with more questionable impact on actual patient outcomes. As L&S use has been shown to increase the risk for vehicle crashes, the secondary concern of ambulance design and safety also becomes an important aspect on potential design recommendations that could mitigate the effects of a crash on patients, EMS providers, and the general public. The least studied aspect of L&S use (and probably the most important) is their effect on patient outcomes and quality of medical care during transport. The current evidence suggests no significant improvement on patient outcomes and potential worsening to certain aspects of patient care during transport. The purpose of this review was to examine the current literature regarding ambulance L&S use and the risks they pose to EMS providers, patients, and the general public. In doing so, it will provide sound background for EMS leaders to better develop policies governing the use of L&S by ambulances and promote better research in the patient outcomes effect associated with their use. This review offers some strategies in mitigating the risks associated with L&S use, such as ways to reduce their overall use and modifying other related factors to emergency medical vehicle collisions (EMVCs).

Given the increasing importance of disaster preparedness in Tehran, the capital of Iran, interventions encouraging disaster preparedness behavior (DPB) are needed. This study was conducted to show how an elicitation method can be used to identify salient consequences, referents, and circumstances about DPB and provide recommendations for interventions and quantitative research.
Method
A theory-based qualitative study using a semi-structured elicitation questionnaire was conducted with 132 heads of households from 22 districts in Tehran, Iran. Following the Theory of Planned Behavior (TPB), six open-ended questions were used to record the opinion of people about DPB: advantages of engaging in DPB; disadvantages of doing so; people who approve; people who disapprove; things that make it easy; and things that make it difficult. Content analysis showed the categories of salient consequences, reference groups, and circumstances.
Results
The three most frequently mentioned advantages obtained from inhabitants of Tehran were health outcomes (eg, it helps us to save our lives, it provides basic needs, and it protects us until relief workers arrive); other salient advantages were mentioned (eg, helps family reunification). The main disadvantage was preparedness anxiety. Family members were the most frequently mentioned social referent when people were asked who might approve or disapprove of their DPB. The two main circumstances perceived to obstruct DPB included not having enough knowledge or enough time.
Conclusion
The results of this qualitative study suggest that interventions to encourage DPB among Tehran inhabitants should address: perceived consequences of DPB on health and other factors beyond health; barriers of not having enough knowledge and time perceived to hinder DPB; and social approval. More accurate research on salient beliefs with close-ended items developed from these open-ended data and with larger sample sizes of Tehran inhabitants is necessary. Research with other stakeholder groups is needed to understand their perceptions about DPB in creating the people’s social environment.

Rural communities face barriers to disaster preparedness and considerable risk of disasters. Emergency preparedness among rural communities has improved with funding from federal programs and implementation of a National Incident Management System. The objective of this project was to design and implement disaster exercises to test decision making by rural response partners to improve regional planning, collaboration, and readiness. Six functional exercises were developed and conducted among three rural Nebraska (USA) regions by the Center for Preparedness Education (CPE) at the University of Nebraska Medical Center (Omaha, Nebraska USA). A total of 83 command centers participated. Six functional exercises were designed to test regional response and command-level decision making, and each 3-hour exercise was followed by a 3-hour regional after action conference. Participant feedback, single agency debriefing feedback, and regional After Action Reports were analyzed. Functional exercises were able to test command-level decision making and operations at multiple agencies simultaneously with limited funding. Observations included emergency management jurisdiction barriers to utilization of unified command and establishment of joint information centers, limited utilization of documentation necessary for reimbursement, and the need to develop coordinated public messaging. Functional exercises are a key tool for testing command-level decision making and response at a higher level than what is typically achieved in tabletop or short, full-scale exercises. Functional exercises enable evaluation of command staff, identification of areas for improvement, and advancing regional collaboration among diverse response partners.

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.
Problem
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.
Methods
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.
Results
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.
Conclusions
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.

The majority of maternal and perinatal deaths are preventable, but still women and newborns die due to insufficient Basic Life Support in low-resource communities. Drawing on experiences from successful wartime trauma systems, a three-tier chain-of-survival model was introduced as a means to reduce rural maternal and perinatal mortality.
Methods
A study area of 266 villages in landmine-infested Northwestern Cambodia were selected based on remoteness and poverty. The five-year intervention from 2005 through 2009 was carried out as a prospective study. The years of formation in 2005 and 2006 were used as a baseline cohort for comparisons with later annual cohorts. Non-professional and professional birth attendants at village level, rural health centers (HCs), and three hospitals were merged with an operational prehospital trauma system. Staff at all levels were trained in life support and emergency obstetrics.
Findings
The maternal mortality rate was reduced from a baseline level of 0.73% to 0.12% in the year 2009 (95% CI Diff, 0.27-0.98; P<.01). The main reduction was observed in deliveries at village level assisted by traditional birth attendants (TBAs). There was a significant reduction in perinatal mortality rate by year from a baseline level at 3.5% to 1.0% in the year 2009 (95% CI Diff, 0.02-0.03; P<.01). Adjusting maternal and perinatal mortality rates for risk factors, the changes by time cohort remained a significant explanatory variable in the regression model.
Conclusion
The results correspond to experiences from modern prehospital trauma systems: Basic Life Support reduces maternal and perinatal death if provided early. Trained TBAs are effective if well-integrated in maternal health programs.

The staffing of ambulances with different levels of Emergency Medical Service (EMS) providers is a difficult decision with evidence being mixed on the benefit of each model.
Hypothesis/Problem
The objective of this study was to describe a pilot program evaluating alternative staffing on two ambulances utilizing the paramedic-basic (PB) model (staffed with one paramedic and one emergency medical technician[EMT]).
Methods
This was a retrospective study conducted from September 17, 2013 through December 31, 2013. The PB ambulances were compared to geographically matched ambulances staffed with paramedic-paramedic (PP ambulances). One PP and one PB ambulance were based at Station A; one PP and one PB ambulance were based at Station B. The primary outcome was total on-scene time. Secondary outcomes included time-to-electrocardiogram (EKG), time-to-intravenous (IV) line insertion, IV-line success rate, and percentage of protocol violations. Inclusion criteria were all patients requesting prehospital services that were attended to by these teams. Patients were excluded if they were not attended to by the study ambulance vehicles. Descriptive statistics were reported as medians and interquartile ranges (IQR). Proportions were reported with 95% confidence intervals (CI). The Mann-Whitley U test was used for significance testing (P<.05).
Results
Median on-scene times at Station A for the PP ambulance were shorter than the PB ambulance team (PP: 10.1 minutes, IQR 6.0-15; PB: 13.0 minutes, IQR 8.1-18; P=.01). This finding also was noted at Station B (PP: 13.5 minutes, IQR 8.5-19; PB: 14.3 minutes, IQR 9.9-20; P=.01). There were no differences between PP and PB ambulance teams at Station A or Station B in time-to-EKG, time-to-IV insertion, IV success rate, and protocol violation rates.
Conclusion
In the setting of a well-developed EMS system utilizing an all-Advanced Life Support (ALS) response, this study suggests that PB ambulance teams may function well when compared to PP ambulances. Though longer scene times were observed, differences in time to ALS interventions and protocol violation rates were not different. Hybrid ambulance teams may be an effective staffing alternative, but decisions to use this model must address clinical and operational concerns.

In November 2013, the Haiyan typhoon hit parts of the Philippines. The typhoon caused severe damage to the medical facilities and many injuries and deaths. Health professionals have a crucial role in the immediate disaster response system, but knowledge of their experiences of working during and in the immediate aftermath of a natural disaster is limited.
Aim
The aim of this study was to explore health professionals’ experiences of working during and in the immediate aftermath of a natural disaster.
Method
Eight health professionals were interviewed five months after the disaster. The interviews were analyzed using phenomenological hermeneutic methods.
Results
The main theme, being professional and survivor, described both positive and negative emotions and experiences from being both a helper, as part of the responding organization, and a victim, as part of the surviving but severely affected community. Sub-themes described feelings of strength and confidence, feelings of adjustment and acceptance, feelings of satisfaction, feelings of powerless and fear, feelings of guilt and shame, and feelings of loneliness.
Conclusion
Being a health professional during a natural disaster was a multi-faceted, powerful, and ambiguous experience of being part of the response system at the same time as being a survivor of the disaster. Personal values and altruistic motives as well as social aspects and stress-coping strategies to reach a balance between acceptance and control were important elements of the experience. Based on these findings, implications for disaster training and response strategies are suggested.
