The preparedness for mass casualty is needed in political event. We have the experience to build up the disaster medical system in G8 summit in Okinawa and Hokkaido. But these two areas were resort area which had little population. This time Japan hosted APEC JAPAN 2010 which held in Yokohama City. We reported disaster medical system for this event in big city.

We mobilized DMAT from 21 hospitals whole Japan. We set 11 teams in Yokohama city, 10 teams in 2 Airports. DMAT inspected rerated disaster base hospitals. These hospitals made the plan for receive mass casualty included the victims by CBRNE event and had the exercise. They set up the decontamination system during APEC leader's week. We also have the contingency plan to coordinate with fire department. This contingency plan included transportation plan for hospitals and coordination plan in site. In transportation plan, sever casualty transported dispersal for hospital in Yokohama within 25. For over 25, sever casualty transported intensive for 4 hospitals in Yokohama. After stabilization treatment in these hospitals, the casualty transported dispersal from these hospitals to outside of Yokohama. In coordinate plan in site included job description in command and control, decontamination and medical relief post.

We established disaster medical system for APEC JAPAN 2010. This event hold in Yokohama City had the big population. Compare with former G8 summit, medical system put importance in mass casualty event. As a result, non mass casualty event happened. But this preparedness will contribute not only future same kind events but also accidental mass casualty event such as train accident.

Healthcare provision depends on reliable infrastructure to power equipment, and provide water for medication and sanitation. Attacks on infrastructure limiting such functions can have a profound and prolonged influence on the delivery of care.

A retrospective analysis of the Global Terrorism Database (GTD) was performed of all attacks occurring between 1970-2020. Data was filtered using the internal database search function for all events where the primary target was “Utilities”, “Food or Water Supply” and “Telecommunications.” For the purposes of this study the subtype “Food Supply” was excluded. Events were collated based on year, country, region, numbers killed and wounded.

The GTD listed 7,813 attacks on infrastructure with 6,280 attacks targeting utilities leading to 1,917 persons directly killed and 1,377 wounded. In total there were 1,265 attacks targeting telecommunications causing 205 direct deaths and 510 wounded. Lastly, 268 attacks targeted the water supply with 318 directly killed and 261 wounded. Regionally, South America had the most attacks with 2,236, followed by Central America and the Caribbean with 1,390. Based on infrastructure type, the most attacks on utilities occurred in El Salvador (1,061), the most attacks on telecommunications were in India (140) and Peru (46) had the most attacks on its water supply.

The regions with the highest number of total attacks targeting infrastructure have historically been in South America, with more attacks against power and utilities than other infrastructure. The numbers of persons directly killed and wounded in these attacks were lower than those with other target types. However, the true impacts these attacks have on lack of health care delivery are not accounted for in these numbers. By understanding the pattern and scope of these attacks, Counter-Terrorism Medicine initiatives can be created to target harden healthcare-related infrastructure.

Many Pacific governments have committed to establishing deployable, self-sufficient national EMTs following recent tropical cyclones, measles outbreaks, and the COVID-19 pandemic. However, for much of the COVD-19 pandemic, PICs have closed international borders limiting in-person team member training.

To develop a remote, interactive EMT training series to engage current and prospective EMT team members in the PICs during the COVID-19 pandemic.

From July through September 2021, WHO hosted a weekly webinar series to introduce the concepts of the EMT Initiative to current and prospective EMT team members in the PICs. The sessions utilized Pacific deployment experience using faculty from EMTs in Australia, Fiji, New Zealand, Papua New Guinea, Solomon Islands, Tonga, and Vanuatu.

Attendees from over 23 countries from across the Pacific and other areas of the world participated in the 11 sessions, with a total of over 300 individual participants. The average number of participants per sessions was 85. Feedback was sought after every session. The most significant adaptation of the sessions from the feedback was incorporating the Pacific tradition of talanoa, or storytelling, into the sessions.

Adapting the session plans to incorporate the talanoa style of communication in the Pacific created an environment of learning from colleagues throughout the Pacific and increased participant engagement in the virtual setting. The webinar series provided knowledge of EMT basics and increased engagement and excitement in the establishment and continued growth of EMTs in the Pacific.

Triaging plays an important role in providing suitable care to the largest number of casualties in a disaster setting. We developed the Pediatric Physiological and Anatomical Triage score (PPATS) as a new secondary triage method.

This study was performed to validate the accuracy of the PPATS in pediatric patients with burn injuries.

A retrospective review of pediatric patients with burn injuries younger than 15 years old registered in the Japan Trauma Databank from 2004 to 2016 was conducted. The PPATS, which was assigned scores from 0 to 22, was calculated based on vital signs, anatomical abnormalities, and need for life-saving intervention. The PPATS categorized the patients by their priority and defined the intensive care unit (ICU)-indicated patients as those with PPARSs more than 6. This study compared the accuracy of prediction of ICU-indicated patients between the PPATS and Triage Revised Trauma Score (TRTS).

Among 87 pediatric patients, 62 (71%) were admitted to the ICU. The median age was 3 years (interquartile range: 1 to 9 years old). The sensitivity and specificity of the PPATS were 74% and 36%, respectively. The area under the receiver-operating characteristic curve was not different between the PPTAS [0.51 (95% confidence interval: -0.51–1.48) and the TRTS [0.51 (-1.17–1.62), p=0.57]. Regression analysis showed a significant association between the PPATS and the Injury Severity Score (ISS) (r2=0.39, p<0.01). On the other hand, there is no association between the TRTS and the ISS (r2=0.00, p=0.79).

The accuracy of the PPATS was not superior to that of current secondary-triage methods. However, the PPATS had the advantage of objectively determining the triage priority ranking based on the severity of the pediatric patients with burn injuries.

New Zealand is widely known across the globe as an adventure tourism destination. On December 9, 2019, the natural wonders of the country became a major disaster that impacted the lives of many and stretched the resources of the New Zealand healthcare system.

Whakaari/White Island is an uninhabited, privately owned island 50 km off the North Island of New Zealand. It contains two strato-volcanoes, which were and remain a popular tourist destination. While an international tourist group were enjoying their guided tour of the crater, one of the volcanoes erupted, sending superheated debris and gas into the air. Of the 47 individuals on the island at the time, 39 were rescued. Overall, 25 people survived. The mortality of this event was significantly lower than historic volcanic eruptions involving ballistic and pyroclastic injuries. We are fortunate to present information specifically on the chemical and physiological changes noted from exposure to volcanic ash.

Located in New Zealand’s largest city is Middlemore Hospital, home of the National Burns Center. This center is supported by three regional burn centers throughout the country. Prior to Whakaari, mass-casualty plans were in place, however, system-wide adaptations were required on many levels to ensure delivery of healthcare. This included changes in pre-hospital triage, support for regional burns centers and repatriation to home countries.

This poster presentation takes you on the journey of adaptation experienced within the National Burns Service, focusing on operating theater, intensive care and acute burns management.

Case Study

The smart glasses were implemented as an innovative communication tool to enhance effectiveness in the field. The traditional mode of communication for Emergency Medical Services (EMS) was radio, which had significant restrictions, primarily that they were unable to transmit any visual data. To enhance efficiency, the smart glasses were used for a more accurate assessment of the condition of patients during transportation. At this time, however, no prior study has shown significant benefits of employing smart glasses into EMS.

The primary objective of this study is to compare the duration of patient care in an ambulance between the use and non-use of smart glasses. The secondary objective is to identify the characteristics of data communication between the ambulance and the hospital.

This retrospective study utilized data gathered from closed-circuit television (CCTV) in ambulances at Srinagarind Hospital, Thailand. The data were collected over a six-month period, specifically from July through December 2021. The study included two groups: the smart glasses group and no smart glasses groups, both used during EMS operations. The primary data collected focused on the duration of patient care in the ambulance. Additionally, the type and characteristics of data transfers via smart glasses during EMS operations were also recorded.

Out of the 256 EMS operations included in this study, 53.1% (N = 68) of the participants in the smart glasses group were male. The majority of operations were performed during the afternoon shift in both groups. The average patient care time in the smart glasses group was 10.07 minutes, while it was 5.10 minutes in the no smart glasses group (P <.001), indicating a significant difference. Visual data communication between the ambulance and the hospital via smart glasses predominantly involved vital signs (100.0%), physical examination (56.3%), and neurological examination (42.2%). The use of audio data from the hospital to the ambulance primarily included taking additional patient history (26.6%) and performing physical examinations (19.5%).

The implementation of smart glasses in EMS operations resulted in an increase in patient care time in the ambulance. Furthermore, the use of smart glasses facilitated an effective channel of real-time two-way communication between the ambulance and the hospital.

The extrication from rubble is particularly critical for the survival of the victims of an earthquake. Early repeated infusion of sedative agents (SAs) in the acute trauma phase may interfere with neural processes leading to posttraumatic stress disorder (PTSD).

This study aimed to analyze the psychological status reported by the buried victims of the earthquake in Amatrice (August 24, 2016; Italy) by considering type of the SAs administered during the extrication maneuvers.

This was an observational study on data from 51 patients directly rescued under the rubble during the earthquake in Amatrice. During extrication maneuvers, a moderate sedation was administered by titrating ketamine (0.3-0.5mg/kg) or morphine (0.1-0.15mg/kg) with respect to the Richmond Agitation and Sedation Scale (RASS; between -2 and -3) in buried victims.

Three years following the rescue, the survivors were interviewed on their perceived health status and stress using a questionnaire which consisted of 17 items: the standard four-item set of healthy days core questions (CDC HRQOL-4); the 12-item General Health Questionnaire (GHQ-12); and in addition, survivors were asked if they had a diagnosis for anxiety, depression, or for PTSD.

The study analyzed data from the complete clinical documentation of 51 survivors; 30 were males and 21 females, with an average age of 52 years. Twenty-six (26) subjects were treated with ketamine, while 25 were treated with morphine, during the extrication procedures. Concerning the quality-of-life analysis, only 10 survivors out of 51 perceived their health status as good; the others reported psychological disorders. The GHQ-12 scores showed that all survivors had psychological distress with a mean total score of 22.2 (SD = 3.5). Eighteen (18) victims declared to have had a diagnosis of generalized anxiety (35%), while 29 were treated for depression (57%) and PTSD (57%) by a specialist. With regards to the perceived distress level and the anxiety disorder, this analysis showed significant associations with SAs used during extrication, with a better performance for ketamine than for morphine.

These findings suggest investigating whether early sedation with ketamine directly in the disaster setting may promote the prophylaxis and reduce the risk of developing trauma-related disorders (TRDs) on the buried victims of major natural disasters in future studies.

Individuals may not receive messages via usual sources. Social media such as Facebook, LinkedIn, Twitter and social networking groups have been useful in the notification, information dissemination, safe notices, and reunification.

A survey of the literature and of social media sites to determine what possibilities of notification, information exchange, marked safe, and reunification information that can be helpful in disasters.

Social media is useful during all phases of a disaster: pre-disaster notification, information dissemination during disasters, and safe notices/reunification post-disaster

Social media is internet-based and requires a device that needs power. There is widespread internet access to various forms of social media, such as email, various broadcast sources, and social networking sites. Social media may provide pre-disaster warnings (weather alert app, reverse 911), evacuation/sheltering information, blocked routes, open gas stations, stores with supplies, hotels/motels with rooms, and shelter locations. Social networking groups were full of messages informing others they could shelter someone fleeing the California wildfires and recent hurricanes. Volunteers can be alerted and responses collected via social media groups. Social media may reach individuals earlier than official announcements, although sometimes accuracy may be in question. Rumor and malignant information source as well as inaccurate information are possible and may need to be managed. Separation is common during disasters. Knowing if their loved ones are safe and well, then reunifying is critical, especially for the vulnerable: children/infants, elderly, and disabled. Reunification systems need safeguards for vulnerable individuals who may be exploited or abused during disasters. In previous disasters (Hurricanes Maria, Mark, and others; California wildfires), when usual communication was nonfunctional due to downed power lines or damaged/destroyed substations; social media was deluged with individuals giving names and identifying information for family and others and asking whether anyone has seen or heard from them.
