Crises, wars, and disasters are remarkably increasing across the world. Responders are frequently tackled with an ever-greater number of challenges, and undoubtedly, they are physically and mentally affected during and after their missions, during which posttraumatic stress disorder (PTSD) is considered high-risk. To the authors’ knowledge, no studies have addressed which type of incident has the greatest influence to trigger stress, and consequently, to cause PTSD for the responders after their missions.

A prospective longitudinal study was conducted with 69 participants of the “Safety and Security” course at the Federal Office for Civil Protection and Disaster Aid of the Federal Ministry of Interior Affairs (Berlin, Germany). The course is certified by the Hostile Environment Awareness Training (HEAT) guidelines of Europe’s New Training Initiative for Civilian Crisis Management (ENTRi; Center for International Peace Operations; Berlin, Germany). Four incidents were evaluated: hostage-taking, carjacking, evacuation, and border-crossing. The participants completed the Positive and Negative Affect Schedule (PANAS) before and after each incident. For each incident, the delta of the PANAS scores was calculated. The differences between the described incidents, as well as the differences between novice and experienced responders, were evaluated.

The hostage-taking incident had the greatest influence on the participants’ temper, followed by carjacking and evacuation. Ultimately, the border-crossing event had the least effect on the responders. Novices were more affected by hostage-taking than experienced responders; however, no significant difference had been demonstrated between novices and experienced responders for the other evaluated incidents.

Different incidents have big psychological impacts on humanitarian responders, in which consequences vary from short-term effects to PTSD. Therefore, humanitarian responders should be selected very carefully. They should also have more specific preparation for their missions. Mental after-care should be obligatory. Further studies are needed to understand and avoid reasons for the development of PTSD or other potential problems of responders.

Political unrest in the Middle East heightens the possibility of catastrophe due to violent conflict and/or terrorist attacks. However, the disaster risk reduction strategy in the Saudi health care system appears to be a reactive approach focused more on flood hazards than other threats. Given the current unstable political situation in its neighboring countries and Saudi Arabia’s key role in providing humanitarian assistance and disaster relief to those affected by internal conflicts and wars, it is essential to develop a framework for training standards related to complex humanitarian disasters to provide the requisite skills and knowledge in a gradual manner, according to local context and international standards. This framework could also support the World Health Organization’s (WHO; Geneva, Switzerland) initiative for establishing a national disaster assistance team in Saudi Arabia.

The main aim of this study is to provide Saudi health care providers with a competencies-based course in Basic Principles of Complex Humanitarian Emergency.

The interactive, competencies-based course in Basic Principles of Complex Humanitarian Emergency was designed by five experts in disaster medicine and humanitarian relief in three stages, accordance to international standards and the local context. The course was piloted over five days at the Officers Club of the Ministry of Interior (MOI; Riyadh, Saudi Arabia). The 33 participants were from different health disciplines of the government sectors in-country. The participants completed the pre- and post-tests and attended three pilot workshops for disaster community awareness.

The overall knowledge scores were significantly higher in the post-test (62.9%) than the pre-test (44.2%). There were no significant differences in the pre- and post-knowledge scores for health care providers from the different government health disciplines. A 10-month, post-event survey demonstrated that participants were satisfied with their knowledge retention. Importantly, three of them (16.6%) had the opportunity to put this knowledge into practice in relation to humanitarian aid response.

Delivering a competencies-based course in Basic Principles of Complex Humanitarian Emergency for health care providers can help improve their knowledge and skills for humanitarian assistance and disaster relief, which is crucial for disaster preparedness augmentation in Saudi Arabia.

Approximately 50,000 patients per year present at emergency departments (EDs) because of carbon monoxide (CO) intoxication. The hypothesis of this study was that the half-life of CO and the regression period of complaints could be reduced more rapidly by applying oxygen with the Continuous Positive Airway Pressure (CPAP) modality using a non-invasive mechanical ventilator.

The patients were divided into Group 1 and Group 2 in terms of the treatment method applied. Patients in Group 1 received FiO2 1.0 15 l/minute oxygen at room temperature for at least 30 minutes with a non-rebreather mask. Patients in Group 2 received FiO2 1.0 oxygen at 12 cmH2O pressure with non-invasive mechanical ventilation for at least 30 minutes with an oronasal mask in the CPAP modality.

The median values (interquartile range) of carboxyhemoglobin (COHb) levels at zero and 30 minutes of patients were 19% (8) and 14% (6) in Group 1 and 22% (8) and nine percent (3) in Group 2; a median difference of six percent (2) was detected in Group 1 and of 13% (4) in Group 2 in the first 30 minutes (P <.001). When the symptoms of the patients were examined, the median values of Group 1 and Group 2 at zero minutes were both eight units and at 30 minutes were five and three units, respectively. A decrease of five units was determined in the median of Group 2 in the first 30 minutes, and a decrease of two units in the median of Group 1 (P <.001).

The use of CPAP was determined to more rapidly reduce COHb level as opposed to high-flow oxygen therapy. It is also thought that it may enable earlier discharge by reducing the duration of the emergency follow-up since it provides a faster improvement in the symptoms of the patients.

Severe trauma can lead to amputation of limbs. There is no golden standard or comprehensive evaluation indicator for amputation. It is difficult for the primary rescue organization to focus on the most essential indicators and to determine whether to perform amputation or take proper operation.

For medical staff in first-line medical teams for disaster relief or in a common primary hospital, what indicators should they focus on to keep the patient’s limbs when they receive wounded patients with severe trauma?

A retrospective case-control study was performed based on the patients with severe trauma from January 2013 through December 2018 in the emergency department of Southwest Hospital (Shapingba District, Chongqing, China), a Level I trauma center. A total of 165 cases were divided into amputation group (n = 79) and non-amputation control group (n = 86), which had severe skin and muscle injury but without amputation. The causes of trauma and the special cases were analyzed. Binary logistic regression models were used to find the essential indicators for amputation.

Neurovascular injury with delayed treatment was the most decisive indicator leading to amputation, and time phase was also important for limb salvage. Preliminary treatment of disaster victims and patients with severe trauma should focus on neurovascular status and timely delivery.

Air medical transport of trauma patients from the scene of injury plays a critical role in the delivery of severely injured patients to trauma centers. Over-triage of patients to trauma centers reduces the system efficiency and jeopardizes safety of air medical crews.

The objective of this study was to determine which triage factors utilized by Emergency Medical Services (EMS) providers are strong predictors of early discharge for trauma patients transported by helicopter to a trauma center.

A retrospective chart review over a two-year period was performed for trauma patients flown from the injury site into a Level I trauma center by an air medical transport program. Demographic and clinical data were collected on each patient. Prehospital factors such as Glasgow Coma Score (GCS), Revised Trauma Score (RTS), intubation status, mechanism of injury, anatomic injuries, physiologic parameters, and any combinations of these factors were investigated to determine which triage criteria accurately predicted early discharge. Hospital factors such as Injury Severity Score (ISS), length-of-stay (LOS), survival, and emergency department disposition were also collected. Early discharge was defined as a hospital stay of less than 24 hours in a patient who survives their injuries. A more stringent definition of appropriate triage was defined as a patient with in-hospital death, an ISS >15, those taken to the operating room (OR) or intensive care unit (ICU), or those receiving blood products. Those patients who failed to meet these criteria were also used to determine over-triage rates.

An overall early discharge rate of 35% was found among the study population. Furthermore, when the more stringent definition was applied, over-triage rates were as high as 85%. Positive predictive values indicated that patients who met at least one anatomic and physiologic criteria were appropriately transported by helicopter as 94% of these patients had stays longer than 24 hours. No other criteria or combination of criteria had a high predictive value for early discharge.

No individual triage criteria or combination of criteria examined demonstrated the ability to uniformly predict an early discharge. Although helicopter transport and subsequent hospital care is costly and resource consuming, it appears that a significant number of patients will be discharged within 24 hours of their transport to a trauma center. Future studies must determine the impact of eliminating “low-yield” triage criteria on under-triage of scene trauma patients.

Bystanders can improve the outcome in emergencies by activating the “chain of survival.” Gaza’s (Palestine) population has little, if any, access to training in Basic Life Support (BLS) and cardiopulmonary resuscitation (CPR). The goal was to recruit local medical students to be life-saving first aid instructors, and have them train 3,000 laypeople in BLS and CPR.

One hundred and seventeen medical students from Al Azhar University-Gaza (Gaza City, Palestine) were trained as BLS and CPR instructors. Twelve training hours were delivered in practical BLS and CPR skills, plus four in communication and didactical skills, to enable training of laypeople. Students answered a questionnaire exploring demographics, prior training experience, expectations, and motivation to join the training. Teaching material were developed after the European Resuscitation Council (ERC; Niel, Belgium) guidelines and similar training at The Arctic University of Norway (Tromsø, Norway).

A total of 117 medical students (52.1% female; 47.9% male), from third through sixth year, completed training, and all were in their early twenties. Ninety-five (81.2%) agreed to answer the questionnaire. Of those, five students lost family members during Israeli military operations. Eighty-two (70.1%) never had hands-on first aid training. Seventy-six (80.0%) hoped the training would improve their community’s response to emergencies. With 58 training sessions completed, 1,312 laypeople (596 males; 716 females) were trained: 5.52 lay trainees per student instructor. The majority (n = 1,012; 77.1%) were school students aged 13–20 years.

It is feasible to recruit local medical students for practical BLS and CPR trainings targeting laypeople in communities under stress. The training impact on local resilience and patients’ outcomes need further studies.

In cases of mass-casualty incidents (MCIs), triage represents a fundamental tool for the management of and assistance to the wounded, which helps discriminate not only the priority of attention, but also the priority of referral to the most suitable center.

The objective of this study was to evaluate the capacity of different prehospital triage systems based on physiological parameters (Shock Index [SI], Glasgow-Age-Pressure Score [GAP], Revised Trauma Score [RTS], and National Early Warning Score 2 [NEWS2]) to predict early mortality (within 48 hours) from the index event for use in MCIs.

This was a longitudinal prospective observational multi-center study on patients who were attended by Advanced Life Support (ALS) units and transferred to the emergency department (ED) of their reference hospital. Collected were: demographic, physiological, and clinical variables; main diagnosis; and data on early mortality. The main outcome variable was mortality from any cause within 48 hours.

From April 1, 2018 through February 28, 2019, a total of 1,288 patients were included in this study. Of these, 262 (20.3%) participants required assistance for trauma and injuries by external agents. Early mortality within the first 48 hours due to any cause affected 69 patients (5.4%). The system with the best predictive capacity was the NEWS2 with an area under the curve (AUC) of 0.891 (95% CI, 0.84-0.94); a sensitivity of 79.7% (95% CI, 68.8-87.5); and a specificity of 84.5% (95% CI, 82.4-86.4) for a cut-off point of nine points, with a positive likelihood ratio of 5.14 (95% CI, 4.31-6.14) and a negative predictive value of 98.7% (95% CI, 97.8-99.2).

Prehospital scores of the NEWS2 are easy to obtain and represent a reliable test, which make it an ideal system to help in the initial assessment of high-risk patients, and to determine their level of triage effectively and efficiently. The Prehospital Emergency Medical System (PhEMS) should evaluate the inclusion of the NEWS2 as a triage system, which is especially useful for the second triage (evacuation priority).

Emergency service (ambulance, police, fire) call-takers and dispatchers are often exposed to duty-related trauma, placing them at increased risk for developing mental health challenges like stress, anxiety, depression, and posttraumatic stress disorder (PTSD). Their unique working environment also puts them at-risk for physical health issues like obesity, headache, backache, and insomnia. Along with the stress associated with being on the receiving end of difficult calls, call-takers and dispatchers also deal with the pressure and demand of following protocol despite dealing with the variability of complex and stressful situations.

A systematic literature review was conducted using the MEDLINE, PubMed, CINAHL, and PsychInfo databases.

A total of 25 publications were retrieved by the search strategy. The majority of studies (n = 13; 52%) reported a quantitative methodology, while nine (36%) reported the use of a qualitative research methodology. One study reported a mixed-methods methodology, one reported an evaluability assessment with semi-structured interviews, one reported on a case study, and one was a systematic review with a narrative synthesis.

Challenges to physical health included: shift-work leading to lack of physical activity, poor nutrition, and obesity; outdated and ergonomically ill-fitted equipment, and physically confining and isolating work spaces leading to physical injuries; inadequate breaks leading to fatigue; and high noise levels and poor lighting being correlated with higher cortisol levels. Challenges to mental health included: being exposed to traumatic calls; working in high-pressure environments with little downtime in between stressful calls; inadequate debriefing after stressful calls; inappropriate training for mental-health-related calls; and being exposed to verbally aggressive callers. Lack of support from leadership was an additional source of stress.

Emergency service call-takers and dispatchers experience both physical and mental health challenges as a result of their work, which appears to be related to a range of both operational and support-based issues. Future research should explore the long-term effects of these physical and mental health challenges.

In the years following the September 11, 2001 terrorist attacks in New York (USA), otherwise known as 9/11, first responders and recovery workers began experiencing a range of physical and mental health challenges. Publications documenting these provide an important evidence-base identifying exposure-related health challenges associated with environmental exposures from the World Trade Center (WTC) site and describe the key lessons learned regarding both physical and mental health challenges (including symptoms and defined conditions) from the 9/11 disaster response.

A systematic literature review was conducted using the MEDLINE, PubMed, CINAHL, and PsychInfo databases (September 11, 2001 to September 11, 2018) using relevant search terms, truncation symbols, and Boolean combination functions. Publications were limited to journal articles that documented the physical or mental health challenges of 9/11 on first responders or recovery workers.

A total of 156 publications were retrieved by the search strategy. The majority (55%) reported a quantitative methodology, while only seven percent reported the use of a qualitative research methodology. Firefighters were the group of responders most frequently reported in the literature (35%), while 37% of publications reported on research that included a mix of first responders and recovery workers. Physical health was the focus of the majority of publications (57%). Among the challenges, respiratory issues were the physical health condition most frequently reported in publications, while posttraumatic stress disorder (PTSD) was the most frequent mental health condition reported on. Publications were published in a broad range of multi-disciplinary journals (n = 75).

These findings will go some way to filling the current gap in the 9/11 evidence-base regarding the understanding of the long-term health challenges for first responders and recovery workers.

Medical responders are at-risk of experiencing a wide range of negative psychological health conditions following a disaster.

Published literature was reviewed on the adverse psychological health outcomes in medical responders to various disasters and mass casualties in order to: (1) assess the psychological impact of disasters on medical responders; and (2) identify the possible risk factors associated with psychological impacts on medical responders.

A literature search of PubMed, Discovery Service, Science Direct, Google Scholar, and Cochrane databases for studies on the prevalence/risk factors of posttraumatic stress disorder (PTSD) and other mental disorders in medical responders of disasters and mass casualties was carried out using pre-determined keywords. Two reviewers screened the 3,545 abstracts and 28 full-length articles which were included for final review.

Depression and PTSD were the most studied outcomes in medical responders. Nurses reported higher levels of adverse outcomes than physicians. Lack of social support and communication, maladaptive coping, and lack of training were important risk factors for developing negative psychological outcomes across all types of disasters.

Disasters have significant adverse effects on the mental well-being of medical responders. The prevalence rates and presumptive risk factors varied among three different types of disasters. There are certain high-risk, vulnerable groups among medical responders, as well as certain risk factors for adverse psychological outcomes. Adapting preventive measures and mitigation strategies aimed at high-risk groups would be beneficial in decreasing negative outcomes.
