Field Methods to Quantify Emergency Responder Fatigue: Lessons Learned from sUAS Deployment at the 2018 Kilauea Volcano Eruption.

OCCUPATIONAL APPLICATIONS There has been increasing use of small unmanned aerial systems in disaster and incident response. We evaluated sUAS pilot states during the tactical response to the 2018 Kilauea Volcano Lower East Rift Zone event, using a 3-minute psychomotor vigilance test (PVT) and wrist worn heart rate sensor. The field data, collected over four days, indicated that the sUAS pilots did not recover to baseline vigilance and physiological levels. Some pilots stopped participating over time, owing to logistical constraints of performing the 3-minute PVT test. Additionally, all pilots refrained from rating their perceived workload levels. We summarize the utility of and challenges associated with collecting performance, physiological, and subjective measures of pilot fatigue during real disaster response.

Emergency response to terrorist attacks: results of the federal-conducted evaluation process in Germany.

PURPOSE: Rescue missions during terrorist attacks are extremely challenging for all rescue forces (police as well as non-police forces) involved. To improve the quality and safety of the rescue missions during an active killing event, it is obligatory to adapt common rescue mission goals and strategies. METHODS: After the recent attacks in Europe, the Federal Office of Civil Protection and Disaster Assistance started an evaluation process on behalf of the Federal Ministry of the Interior and the Federal Ministry of Health. This was done to identify weaknesses, lessons learned and to formulate new adapted guidelines. RESULTS: The presented bullet point recommendations summarise the basic and most important results of the ongoing evaluation process for the Federal Republic of Germany. The safety of all the rescue forces and survival of the greatest possible number of casualties are the priority goals. Furthermore, the preservation and re-establishment of the socio-political integrity are the overarching goals of the management of active killing events. Strategic incident priorities are to stop the killing and to save as much lives as possible. The early identification and prioritised transportation of casualties with life-threatening non-controllable bleeding are major tasks and the shortest possible on-scene time is an important requirement with respect to safety issues. CONCLUSION: With respect to hazard prevention tactics within Germany, we attributed the highest priority impact to the bullet points. The focus of the process has now shifted to intense work about possible solutions for the identified deficits and implementation strategies of such solutions during mass killing incidents.

Developing a tool for measuring the disaster resilience of healthcare rescuers: a modified Delphi study.

BACKGROUND: Disaster resilience is an essential personal characteristics of health rescue workers to respond to disasters in an effective manner, and maintain a state of adaptation after deployment. It is essential for disaster managers to recruit, assess, and prepare healthcare rescuers with this characteristic. A specific tool for measuring the disaster resilience of healthcare rescuers has yet to be devised. OBJECTIVE: The purpose of this study was to establish the content validity of a tool for measuring the disaster resilience of disaster rescue workers. METHODS: A modified Delphi approach was employed. Experts in disaster work and research were invited to rate the domains and items of a prototype tool for measuring disaster resilience in healthcare rescue workers. The panel of experts rated the relevance of the items using a 4-point Likert scale. The median and interquartile range, as well as the level of agreement, were calculated for each item using the Kendall coefficient W, to assess the consensus of the experts. The content validity index (CVI) was calculated to assess the content validity of this tool. RESULTS: A total of 22 and 21 experts were involved in the first and second rounds of this modified Delphi study (response rate of 91.7 and 95.5%), respectively. After two rounds of expert query, an eight-domain and 27-item disaster resilience measuring tool was established. The median range of all of the included items was 3.50 to 4.00 and the interquartile range was 0.00 to 1.00, and all items achieved ≥85% agreement. The Kendall coordination coefficient W was 0.21 and 0.33 in the first and second rounds, respectively, with P < 0.01. The I-CVI ranged from 0.85 to 1.0, while the S-CVI/UA and S-CVI /Ave were 0.69 and 0.97, respectively. CONCLUSION: Consensus was reached on a disaster resilience measuring tool covering 27 items. The content validity of this tool for measuring the disaster resilience of healthcare rescuers was excellent. This tool is validated and ready to be tested in a pilot study to assess its psychometric properties.

Prehospital management provided by medical on-scene commanders in tunnel incidents in Oslo, Norway - an interview study.

BACKGROUND: High demands are placed on the emergency medical services to handle rescue operations in challenging environments such as tunnels. In Oslo, Norway a specialised management function within the emergency medical services, the medical on-scene commander, in line with the command structure within the police and fire brigade, might support or take over command and control from the ambulance incident officer arriving as the first ambulance personnel on scene. The aim was to shed light on the emergency medical service experiences from real tunnel incidents described by the Oslo medical on-scene commanders. METHODS: Interviews were conducted with six of the seven medical on-scene commander in Oslo, Norway. Data were analysed using a qualitative content analysis. RESULTS: The overall theme was "A need for mutual understanding of a tunnel incident". The medical on-scene commander provided tactical support, using their special knowledge of risk objects and resources in the local area. They established operation plans with other emergency services (the police and fire brigade) in a structured and trustful way, thus creating a fluent and coordinated mission. Also, less time was spent arguing at the incident site. By socialising also outside ordinary working hours, a strong foundation of reliance was built between the different parties. A challenge in recent years has been the increasing ordinary workload, giving less opportunity for training and exchange of experiences between the three emergency services. CONCLUSIONS: The enthusiastic pioneers within the three emergency services have created a sense of familiarity and trust. A specially trained medical on-scene commander at a tunnel incident is regarded to improve the medical management. To improve efficiency, this might be worth studying for other emergency medical services with similar conditions, i.e. tunnels in densely populated areas.

Identifying Crucial Equipment and Skills Needed to Evacuate Critically Ill Infants During Disasters: Using Nursing Expertise to Guide Training Targets.

INTRODUCTION: Unexpected disasters, such as earthquakes or fires, require preparation to address knowledge gaps that may negatively affect vulnerable patients. Training programs can promote natural disaster readiness to respond and evacuate patients safely, but also require evidence-based information to guide learning objectives. PROBLEM: There is limited evidence on what skills and bedside equipment are most important to include in disaster training and evacuation programs for critically ill infants. METHODS: An expert panel was used to create a 13-item mastery checklist of skills for bedside registered nurses (RNs) required to successfully evacuate a critically ill infant. Expert nurses were surveyed, and the Angoff method was used to determine which of the mastery checklist skills a newly graduated nurse (ie, the "minimally competent" nurse) should be able to do. Participants then rated the importance of 26 commonly available pieces of bedside equipment for use in evacuating a hemodynamically unstable, intubated infant during a disaster. RESULTS: Twenty-three emergency department (ED) and neonatal intensive care unit (NICU) charge RNs responded to the survey with a mean of 19 (SD = 9) years of experience and 30% reporting personal experience with evacuating patients. The skills list scores showed an emphasis on the newly graduated nurse having more complete mastery of skills surrounding thermoregulation, documentation, infection control, respiratory support, and monitoring. Skills for communication, decision making, and anticipating future needs were assessed as less likely for a new nurse to have mastered. On a scale of one (not important) to seven (critically important), the perceived necessity of equipment ranged from a low of 1.6 (breast pump) to a high of 6.9 (face mask). The individual intraclass correlation coefficient (ICC) of 0.55 showed moderate reliability between raters and the average team ICC of 0.97 showed excellent agreement as a group. CONCLUSION: Experts rated the ability to manage physiological issues, such as thermoregulation and respiratory support, as skills that every nurse should master. Disaster preparedness activities for nurses in training may benefit from checklists of essential equipment and skills to ensure all nurses can independently manage patients' physiologic needs when they enter the workforce. Advanced nursing training should include education on decision making, communication during emergencies, and anticipation of future issues to ensure that charge and resource nurses can support bedside nurses during evacuation events.

Overcommitment: Management in Helicopter Emergency Medical Services in Norway.

OBJECTIVE: Overcommitment in demanding rescue situations may put both rescuers and patients in danger. This study aimed at identifying individual approaches and organizational strategies that counteract instances in which rescuers commit more than is feasible, desirable, expected, recommended, or compellingly necessary. How is overcommitment managed by professional frontline rescuers during hazardous medical evacuation and rescue situations? METHODS: In a qualitative, exploratory study, 9 focus group interviews were conducted with a total of 30 crewmembers from the Norwegian Helicopter Emergency Medical Service. RESULTS: In this second article in a series of 2 articles on overcommitment, 12 commitment-moderating factors are presented. Air ambulance personnel pointed at sociological, cognitive, and organizational elements that may influence their degree of commitment in challenging and hazardous rescue situations. CONCLUSION: Air ambulance personnel describe a team-based approach to adjust their level of commitment in medical evacuation and rescue missions. They rely on known, however important, nontechnical skills and organizational measures to combat overcommitment in demanding rescue situations. Some of their approaches to safe performance should be adoptable by other rescue units and less experienced voluntary, not-for-profit, rescue organizations.

Consideration of Medical and Public Health Coordination - Experience from the 2016 Kumamoto, Japan Earthquake.

OBJECTIVE: The aim of this study was to identify disaster medical operation improvements from the 2016 Kumamoto Earthquake (Kumamoto Prefecture, Japan) and to extract further lessons learned to prepare for future expected major earthquakes. METHODS: The records of communications logs, chronological transitions of chain of command, and team registration logs for the Disaster Medical Assistant Team (DMAT), as well as other disaster medical relief teams, were evaluated. RESULTS: A total of 466 DMAT teams and 2,071 DMAT team members were deployed to the Kumamoto area, and 1,894 disaster medical relief teams and 8,471 disaster medical relief team member deployments followed. The DMAT established a medical coordination command post at several key disaster hospitals to designate medical coverage areas. The DMAT evacuated over 1,400 patients from damaged hospitals, transported medical supplies to affected hospitals, and coordinated 14 doctor helicopters used for severe patient transport. To keep constant medical and public health operations, DMAT provided medical coordination management until the local medical coordination was on-track. Several logistic teams, which are highly trained on operation and management of medical coordination command, were dispatched to assist management operation. The DMAT also helped to establish Disaster Coordination and Management Council at the prefectural- and municipal-level, and also coordinated command control for public health operations. The DMAT could provide not only medical assistance at the acute phase of the disaster, but also could provide medical coordination for public health and welfare. CONCLUSION: During the 2016 Kumamoto Earthquake, needs of public health and welfare increased enormously due to the sudden evacuation of a large number of residents. To provide constant medical assistance at the disaster area, DMAT, logistic teams, and other disaster medical relief teams must operate constant coordination at the medical headquarter command. For future expected major earthquakes in Japan, it will be required to educate and secure high enough numbers of disaster medical assistance and health care personnel to provide continuous medical and public health care for the affected area residents.Kondo H, Koido Y, Kawashima Y, Kohayagawa Y, Misaki M, Takahashi A, Kondo Y, Chishima K, Toyokuni Y.

[Exploration of design and practice of disaster medical rescue monitoring system with privacy protection mechanism].

OBJECTIVE: On the premise of fully studying the disaster medical rescue monitoring mechanism in emergencies at home and abroad, the functional requirements of the domestic disaster medical rescue monitoring system was analyzed in this paper, the logical framework and data structure of disaster medical rescue monitoring system with privacy protection mechanism was designed by department of emergency in Chinese PLA General Hospital, department of information management in School of Economics and Management of Beijing Jiaotong University, the School of Information Management of Nanjing University. Three major functional modules were realized in the system: reporter information management, disaster medical rescue data upload, and disaster medical rescue data search. Android client and Web client were developed for easy access to the system. The system also had the function of privacy protection. Based on symmetric searchable encryption algorithm, the system realized the encryption storage of untrusted servers and ensured the security of medical and health data. It is beneficial for the further development and improvement of disaster medical rescue data collection in China.

Patient and rescuer safety: recommendations for dispatch and prioritization of rescue resources based on a retrospective study of Norwegian avalanche incidents 1996-2017.

BACKGROUND: Avalanche emergency response should address current accident scenarios to optimize survival chances of victims and to keep rescuers safe. The purpose of this article is to present a basis for evaluation and necessary adjustments in dispatch, prioritization, and management of Norwegian avalanche rescue operations. METHODS: This is the first peer-reviewed retrospective study of all Norwegian avalanche incidents registered by the two Joint Rescue Co-ordination Centers (JRCCs) in the period 1996-2017 that describes the characteristics and trends of rescue missions and victims. RESULTS: The Norwegian JRCCs have registered 720 snow avalanche events, with a total of 568 avalanche victims, of which 120 (21%) died. Including those fatally injured, a total of 313 avalanche victims in 209 accidents were treated as patients (55%), and we saw > 1 patient in 24% of these operations. Norwegian avalanche victims were partially or completely recovered prior to the arrival of rescuers in 75% (n = 117) of all rescue operations. In the remaining 25% of cases, the rescue service located 62% (n = 55) of the avalanche victims visually or electronically. In 50% of the 720 incidents, rescuers spent time searching in avalanches with no victims. CONCLUSIONS: This survey indicates that we have experienced a shift in Norwegian avalanche rescue: from search for missing persons in the avalanche debris to immediate medical care of already-located patients. The findings suggest that a stronger focus on both patient and rescuer safety is necessary. The patients must be ensured the right treatment at the right place at the right time and the allocation of rescue resources must reflect a need to reduce exposure in avalanche terrain, especially in cases with no affirmed victims. We present a flowchart with a recommended rescue response to avalanche accidents in Norway.

Incidence and strategies for preventing sustained hypothermia of crash victims during prolonged vehicle extrication.

BACKGROUND: Vehicle extrication of crash victims is a highly-demanding challenge, due to the frequently life-threatening injuries of entrapped occupants. In this phase, crash victims are often exposed to the outdoor-temperature, with the risk of sustained hypothermia. Hypothermia can significantly raise the morbidity and mortality rates of crash victims. Therefore, we have correlated the incidence of severe car accidents with entrapped patients, the outdoor conditions, and expenditure of time for extrication. Furthermore, different warming strategies have been evaluated regarding their integrability within the rescue procedure. METHODS: To estimate the incidence of severe car accidents with entrapped patients, we performed retrospective data mining for the cold season of a three-year period in a rural district in Germany. We evaluated the integrability of a chemical heated blanket, its combined application with a forced-air warmer, or with an infrared radiator for patient warming. Therefore, we analysed the time tracking of extrication reference points during extrication exercises undertaken by the rescue services, simulating a severe vehicle accident and evaluated questionnaires administered to rescue personnel and subjects. Furthermore, we monitored subjects' physiologic parameters to estimate the warming effect. RESULTS: Incidence analysis resulted in extrication times of up to 80 min, representing two severely-entrapped patients per month in the cold seasons, corresponding to about four entrapments per 100.000 inhabitants every year. Of the different warming strategies analysed, the chemical blanket and the combination infrared radiator/chemical blanket were favoured regarding the items 'operator convenience', 'weight/size/handling', 'stability in positioning', 'time needed for installation', 'manpower requirement', 'hindrance during extrication operation', 'versality during extrication process', and 'robustness' by the rescue personnel; the forced-air warmer and the infrared radiator were preferred with regard to 'warming effect', the forced-air warmer and the chemical blanket was advantageous with regard to 'physical protection'. CONCLUSIONS: Vehicle extrication procedures are time consuming, a relevant finding that provides a rationale for discussing and optimising the rescue procedure to prevent sustained hypothermia. We determined that combined application of an infrared radiator and a chemical blanket is advantageous in terms of integration into the rescue process. However, a more detailed investigation, focussing on warming efficacy, must be performed.

Evacuation of Swedish survivors after the 2004 Southeast Asian tsunami: The survivors' perspective and symptoms of post-traumatic stress.

AIMS: Following the 2004 Southeast Asian tsunami, Swedish authorities received public criticism for slow implementation of rescue work. Meanwhile, data are scarce on survivors' perspectives and potential mental health symptoms associated with timing of evacuation. Therefore, the aim of this study was to investigate survivors' contentment with evacuation time and whether duration at disaster site following the 2004 tsunami was associated with post-traumatic stress symptoms (PTSS) and psychological morbidity. METHODS: Of 10,116 Swedish tsunami survivors who returned to Sweden in the first 3 weeks post tsunami, 4910 (49%) answered a questionnaire 14 months later including questions on evacuation time, contentment with evacuation time and PTSS (Impact of Event Scale). We used logistic regression to calculate odds ratios (OR) and 95% confidence intervals (95% CI) of PTSS by timing of evacuation adjusting for gender, age, education, various indicators of trauma exposure and pre-tsunami psychiatric diagnoses. RESULTS: More than half of the survivors (53%) were content with evacuation time while 33% wanted later evacuation and 13% earlier evacuation. Compared with those evacuated 14-21 days post tsunami, individuals evacuated at day 1-4 presented with increased odds of PTSS (crude OR 3.0, 95% CI 2.0-4.5; and multivariable adjusted OR 2.0, 95% CI 1.3-3.0) and impaired mental health (crude OR 1.7, 95% CI 1.2-2.4; and multivariable adjusted OR 1.4 95% CI 1.0-2.0). CONCLUSIONS: One-third of Swedish tsunami survivors preferred a later evacuation from disaster sites. These findings call for further studies, with prospective designs, to disentangle the causal direction of the association between evacuation time and PTSS.

Willingness of Emergency Medical Services Professionals to Respond to an Active Shooter Incident.

BACKGROUND: Historically, staging of civilian emergency medical services (EMS) during an active shooter incident was in the cold zone while these professionals awaited the scene to be completely secured by multiple waves of law enforcement. This delay in EMS response has led to the development of a more effective method: the Rescue Task Force (RTF). The RTF concept has the second wave of law enforcement escorting civilian EMS into the warm zone, thus decreasing EMS response time. To our knowledge, there are no data regarding the willingness of EMS professionals to enter a warm zone as part of an RTF. In this study, we assessed the willingness of EMS providers to respond to an active shooter incident as part of an RTF. METHODS: A survey was distributed at an annual, educational EMS conference in North Carolina. The surveys were distributed on the first day of the conference at the beginning of a general session that focused on EMS stress and wellness. Total attendance was measured using identification badges and scanners on exiting the session. Data were assessed using χ2 analysis, as were associations between demographics of interest and willingness to respond under certain conditions. A p value < .01 indicated statistical significance. RESULTS: The overall response rate was 76% (n = 391 of 515 session attendees). Most surveys were completed by paramedics (74%; n = 288 of 391). Most EMS professionals (75%; n = 293 of 391) stated they would respond to the given active shooter scenario as part of an RTF (escorted by the second wave of law enforcement) if they were given only ballistic gear. However, most EMS professionals (61%; n = 239 of 391) stated they would not respond if they were provided no ballistic gear and no firearm. Those with tactical or military training were more willing to respond with no ballistic gear and no firearm (49.6%; n = 68 of 137) versus those without such training (31%; n = 79 of 250; odds ratio, 2.2; 95% confidence interval, 1.4-3.3; p < .001). CONCLUSION: EMS professionals are willing to put themselves in harm's way by entering a warm zone if they are simply provided the proper training and ballistic equipment.

Regional whole-course trauma care - Experiences from a county-level hospital.

Fifty percent of the deaths caused by severe trauma occur within 1 h after injury. With the concepts of "golden 1 h" and "platinum 10 min", the professionals in the field of emergency trauma treatment have agreed on the necessity of establishing a rapid and efficient trauma rescue system. However, due to the size of the hospital, the population in the neighborhood, the local economic conditions and geographical features, how to establish an optimal trauma rescue system remains an issue. In this paper, we introduced our experiences in a county-level hospital located in middle-and high-income areas.

Optimizing stadium evacuation by integrating geocomputation and affordance theory.

Football is culturally and economically important in the United States, and football stadiums are part of the country's critical infrastructure, thus receiving government protection against hazard events. In this project, an agent-based evacuation model was implemented to optimize evacuation time from The University of Southern Mississippi's M.M. Roberts Stadium (football) by accounting for evacuees' age, gender, physical fitness, alcohol consumption, and prior experience with hazard events. The findings revealed that (i) the age and gender of an individual impact his/her locomotion speed and (ii) evacuation route choice is influenced by evacuees' perception of its safety and effectiveness. The estimated evacuation times for all evacuees to exit only the stadium and the stadium plus the surrounding campus were 20.82 and 165.01 minutes, respectively. Both of these times were shorter than the evacuation times determined by models employing location-unspecific locomotion speeds. One-way analysis of variance revealed that there were statistically significant differences between use of location-specific and location-unspecific within-stadium evacuation times (p ≤ 0.001 with α = 0.05). These results suggest that using local data is vital to accurately estimate evacuation time.
