Exploring the Gender and Age Demographics of Patients Treated by Emergency Medical Teams during Disasters.

BACKGROUND: Standardized health-data collection enables effective disaster responses and patient care. Emergency medical teams use the Japan Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED) reporting template to collect patient data. EMTs submit data on treated patients to an EMT coordination cell. The World Health Organization's (WHO) EMT minimum dataset (MDS) offers an international standard for disaster data collection. GOAL: The goal of this study was to analyze age and gender distribution of medical consultations in EMT during disasters. METHODS: Data collected from 2016 to 2020 using the J-SPEED/MDS tools during six disasters in Japan and Mozambique were analyzed. Linear regression with data smoothing via the moving average method was employed to identify trends in medical consultations based on age and gender. RESULTS: 31,056 consultations were recorded: 13,958 in Japan and 17,098 in Mozambique. Women accounted for 56.3% and 55.7% of examinees in Japan and Mozambique, respectively. Children accounted for 6.8% of consultations in Japan and 28.1% in Mozambique. Elders accounted for 1.32 and 1.52 times more consultations than adults in Japan and Mozambique, respectively. CONCLUSIONS: Study findings highlight the importance of considering age-specific healthcare requirements in disaster planning. Real-time data collection tools such as J-SPEED and MDS, which generate both daily reports and raw data for in-depth analysis, facilitate the validation of equitable access to healthcare services, emphasize the specific needs of vulnerable groups, and enable the consideration of cultural preferences to improve healthcare provision by EMTs.

Medical needs during the Kumamoto heavy rain 2020: analysis from emergency medical teams' responses.

BACKGROUND: Rainfall-induced floods represented 70% of the disasters in Japan from 1985 to 2018 and caused various health problems. To improve preparedness and preventive measures, more information is needed on the health problems caused by heavy rain. However, it has proven challenging to collect health data surrounding disasters due to various inhibiting factors such as environmental hazards and logistical constraints. In response to the Kumamoto Heavy Rain 2020, Emergency Medical Teams (EMTs) used J-SPEED (Japan-Surveillance in Post Extreme Emergencies and Disasters) as a daily reporting tool, collecting patient data and sending it to an EMTCC (EMT Coordination Cell) during the response. We performed a descriptive epidemiological analysis using J-SPEED data to better understand the health problems arising from the Kumamoto Heavy Rain 2020 in Japan. METHODS: During the Kumamoto Heavy Rain 2020 from July 5 to July 31, 2020, 79 EMTs used the J-SPEED form to submit daily reports to the EMTCC on the number and types of health problems they treated. We analyzed the 207 daily reports, categorizing the data by age, gender, and time period. RESULTS: Among the 816 reported consultations, women accounted for 51% and men accounted for 49%. The majority of patients were elderly (62.1%), followed by adults (32.8%), and children (5%). The most common health issues included treatment interruption (12.4%), hypertension (12.0%), wounds (10.8%), minor trauma (9.6%), and disaster-related stress symptoms (7.4%). Consultations followed six phases during the disaster response, with the highest occurrence during the hyperacute and acute phases. Directly disaster-related events comprised 13.9% of consultations, indirectly related events comprised 52.0%, and unrelated events comprised 34.0%. As the response phases progressed, the proportions of directly and indirectly related events decreased while that of unrelated events increased. CONCLUSION: By harnessing data captured by J-SPEED, this research demonstrates the feasibility of collecting, quantifying, and analyzing data using a uniform format. Comparison of the present findings with those of two previous analyses of J-SPEED data from other disaster scenarios that varied in time, location, and/or disaster type showcases the potential to use analysis of past experiences to advancing knowledge on disaster medicine and disaster public health.

Emergency Medical Team Response during the Hokkaido Eastern Iburi Earthquake 2018: J-SPEED Data Analysis.

INTRODUCTION: In the last ten years, Japan has experienced several large-scale earthquakes with devastating social and health impacts. Earthquakes directly and indirectly cause a variety of health problems. Further investigation is required to increase preparedness and preventive efforts. In response to the Hokkaido Eastern Iburi Earthquake on September 6, 2018, 32 Emergency Medical Teams (EMTs) employed the Japanese version of Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED) as a national standard daily reporting template, gathering data on the number and type of health problems treated. STUDY OBJECTIVE: The purpose of the study is to conduct a descriptive epidemiology study using the J-SPEED data to better understand the health problems during the earthquake disaster. METHODS: Reported items in J-SPEED (Ver 1.0) form were analyzed by age, gender, and time to better understand the health issues that have arisen from the earthquake. RESULTS: Most consultations (721; 97.6%) occurred between Day 1 and Day 13 of the 32-day EMT response. During the response period, disaster stress-related symptoms were the most common health event (15.2%), followed by wounds (14.5%) and skin diseases (7.0%). CONCLUSION: The most often reported health event during the response period was stress-associated illnesses related to disasters, followed by wounds and skin conditions. The health consequences of natural disasters depend on diverse local environment and population. As a result, this initial study was hard to generalize; however, it is expected that data accumulated using the J-SPEED system in the future will strengthen and extend the conclusions.

First Activation of the WHO Emergency Medical Team Minimum Data Set in the 2019 Response to Tropical Cyclone Idai in Mozambique.

INTRODUCTION: During a disaster, comprehensive, accurate, timely, and standardized health data collection is needed to improve patient care and support effective responses. In 2017, the World Health Organization (WHO) developed the Emergency Medical Team (EMT) Minimum Data Set (MDS) as an international standard for data collection in the context of disasters and public health emergencies. The EMT MDS was formally activated for the first time in 2019 during the response to Cyclone Idai in Mozambique. STUDY OBJECTIVE: The aim of this study was to analyze data collected through the EMT MDS during Cyclone Idai of 2019 and to identify the benefits of and opportunities for its future use. METHODS: The EMT MDS was used for data collection. All 13 international EMTs deployed from March 27 through July 12 reported data in accordance with the EMT MDS form. The collected data were analyzed descriptively. RESULTS: A total of 18,468 consultations, including delivery of 94 live births, were recorded. For children under-five and those five-years and older, the top five reasons for consultation were minor injuries (4.5% and 10.8%, respectively), acute respiratory infections ([ARI] 12.6% and 4.8%, respectively), acute watery diarrhea (18.7% and 7.7%, respectively), malaria (9.2% and 6.1%, respectively), and skin diseases (5.1% and 3.1%, respectively). Non-disaster-related health events accounted for 84.7% of the total health problems recorded. Obstetric care was among the core services provided by EMTs during the response. CONCLUSION: Despite of challenges, the EMT MDS reporting system was found to support the responses and coordination of EMTs. The role of the Mozambican Ministry of Health (MOH), its cooperation with EMTs, and the dedicated technical support of international organizations enabled its successful implementation.

Prevalence of Mental Health Problems among Patients Treated by Emergency Medical Teams: Findings from J-SPEED Data Regarding the West Japan Heavy Rain 2018.

It is crucial to provide mental health care following a disaster because the victims tend to experience symptoms such as anxiety and insomnia during the acute phase. However, little research on mental health during the acute phase has been conducted, and reported only in terms of the temporal transition of the number of consultations and symptoms. Thus, the aim of the study was to examine how mental health care needs are accounted for in the overall picture of disaster relief and how they change over time. Using data from the Japanese version of Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED), we assessed the mental health of injured and ill patients to whom Emergency Medical Teams (EMTs) were providing care during the acute period of a disaster. Approximately 10% of all medical consultations were for mental health issues, 83% of which took place within the first 2 weeks after the disaster. The findings showed that, from the start of the response period to the 19th response day, the daily proportion of mental health problems declined substantially, and then gradually increased. Such a V-shaped pattern might be helpful for identifying phase changes and supporting the development of EMT exit strategies.

Impact of the ARCH Project on National Capacity Development on Disaster Health Management among the ASEAN Member States and Japan.

OBJECTIVE: This report tries to capture the impact of the Project for Strengthening the ASEAN Regional Capacity on Disaster Health Management (ARCH Project) in each ASEAN Member State (AMS) and Japan as a result of the ARCH Project implementation since July 2016. METHODS: Impact on AMS: The analysis of the impact on AMS was based on a comparison of the impact of the project on management and coordination of Emergency Medical Teams (EMTs), and application of the project outcome in actual emergency operations compared to the previous status in each AMS.Impact on Japan: The history of the development of disaster medicine in Japan was reviewed, with an aim to analyze the impact of supporting AMS through the ARCH Project on Japan, and the possibility of bi-directional cooperation in the future. RESULTS: Impact on AMS: Since the initiation of the ARCH Project, AMS has made significant progress in WHO EMT accreditation, strengthening EMTCC capacity for receiving international assistance, as well as the development of legislation or strategic plans related to DHM, and application of the Project products such as standard operating procedures or regional tools in actual disasters/emergencies.Impact on Japan: Disaster medicine in Japan originated from the Cambodian refugees' relief mission in 1979. Since then, the management system has been strengthened including the foundation of the Japan Disaster Relief (JDR) Team, a structure with a legal foundation. The experience gained through international operations has contributed to the development of Japan's domestic disaster response system. Japan learned the operational effectiveness of the post-disaster health surveillance system through the disaster response operation in 2013 Typhoon Yolanda Disaster in Philippines and introduced a modified system in Japan for domestic disaster response, which was later refined and proposed for an international standard. CONCLUSION: ARCH Project is highly appreciated by AMS as the opportunity to share knowledge and experience among countries and thereby contributing to achieving the "One ASEAN, One Response" concept, as well as the driving force for each AMS to develop its capacity in DHM. While the ARCH Project started to support AMS to strengthen its regional capacity in disaster health management, it is important to build a bi-directional relationship between ASEAN and Japan in terms of mutual learning and support to tackle future disasters.

ARCH Project and the Global Initiatives of Disaster Health Management.

OBJECTIVE: The prime aim of Project for Strengthening the ASEAN Regional Capacity on Disaster Health Management (ARCH Project) is to strengthen the disaster health management (DHM) capacity in the context of personal level, Emergency Medical Team (EMT), and the regional collaboration. The ARCH Project was implemented with reference to international trends of DHM and seeks to contribute to the development of global standards. METHODS: The project established the Project Working Groups that consisted of representatives of ASEAN Member States (AMS) to develop standard operating procedures (SOP) for international EMT (I-EMT) coordination. Furthermore, it aimed to organize training sessions along with implementation of the regional collaboration drill (RCD) in accordance with I-EMT minimum requirements and in line with coordination standards set by the WHO. RESULTS: The ARCH Project developed the SOP and common platform for I-EMT coordination, organized training, and conducted RCDs with reference to the WHO's EMT initiative. Furthermore, it also contributed to the development of the EMT Minimum Data Set (MDS), an international standard DHM tool that underwent testing at the RCDs before the WHO endorsement and its utilization in actual disaster response. CONCLUSION: In the process of strengthening ASEAN regional capacity in DHM, the project is constantly capturing international trends and also making significant contributions in the development of global systems and tools.

Emergency Medical Teams' Responses during the West Japan Heavy Rain 2018: J-SPEED Data Analysis.

INTRODUCTION: Rainfall-induced floods and landslides accounted for 20.7% of all disaster events in Japan from 1985 through 2018 and caused a variety of health problems, both directly and indirectly, including injuries, infectious diseases, exacerbation of pre-existing medical conditions, and psychological issues. More evidence of health problems caused by floods or heavy rain is needed to improve preparedness and preventive measures; however, collecting health data surrounding disaster events is a major challenge due to environmental hazards, logistical constraints, political and economic issues, difficulties in communication among stakeholders, and cultural barriers. In response to the West Japan Heavy Rain in July 2018, Emergency Medical Teams (EMTs) used Japan - Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED) as a daily reporting template, collecting data on the number and type of patients they treated and sending it to an EMT coordination cell (EMTCC) during the response. STUDY OBJECTIVE: The aim of the study was to conduct a descriptive epidemiology study using J-SPEED data to better understand the health problems during floods and heavy rain disasters. METHODS: The number and types of health problems treated by EMTs in accordance with the J-SPEED (Ver 1.0) form were reported daily by 85 EMTs to an EMTCC, where data were compiled during the West Japan Heavy Rain from July 8 through September 11, 2018. Reported items in the J-SPEED form were analyzed by age, gender, area (prefecture), and time period. RESULTS: The analysis of J-SPEED data from the West Japan Heavy Rain 2018 revealed the characteristics of a total of 3,617 consultations with the highest number of consultations (2,579; 71.3%) occurring between Day 5 and Day 12 of the 65-day EMT response. During the response period, skin disease was the most frequently reported health event (17.3%), followed by wounds (14.3%), disaster stress-related symptoms (10.0%), conjunctivitis (6.3%), and acute respiratory infections (ARI; 5.4%). CONCLUSION: During the response period, skin disease was the most frequently reported health event, followed by wounds, stress, conjunctivitis, and ARIs. The health impacts of a natural disaster are determined by a variety of factors, and the current study's findings are highly context dependent; however, it is expected that as more data are gathered, the consistency of finding will increase.

Incidence of Acute Respiratory Infections during Disasters in the Absence and Presence of COVID-19 Pandemic.

INTRODUCTION: Japan recently experienced two major heavy rain disasters: the West Japan heavy rain disaster in July 2018 and the Kumamoto heavy rain disaster in July 2020. Between the occurrences of these two disasters, Japan began experiencing the wave of the coronavirus disease 2019 (COVID-19) pandemic, providing a unique opportunity to compare the incidence of acute respiratory infection (ARI) between the two disaster responses under distinct conditions. SOURCES FOR INFORMATION: The data were collected by using the standard disaster medical reporting system used in Japan, so-called the Japan-Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED), which reports number and types of patients treated by Emergency Medical Teams (EMTs). Data for ARI were extracted from daily aggregated data on the J-SPEED form and the frequency of ARI in two disasters was compared. OBSERVATION: Acute respiratory infection in the West Japan heavy rain that occurred in the absence of COVID-19 and in the Kumamoto heavy rain that occurred in the presence of COVID-19 were responsible for 5.4% and 1.2% of the total consultation, respectively (P <.001). ANALYSIS OF OBSERVATION AND CONCLUSION: Between the occurrence of these two disasters, Japan implemented COVID-19 preventive measures on a personal and organizational level, such as wearing masks, disinfecting hands, maintaining social distance, improving room ventilation, and screening people who entered evacuation centers by using hygiene management checklists. By following the basic prevention measures stated above, ARI can be significantly reduced during a disaster.

Near-miss incidents owing to fatigue and irregular lifestyles in ambulance personnel.

We aimed to investigate the association between fatigue and near-miss incidents and between irregular lifestyles and fatigue in ambulance personnel. In this cross-sectional study, we used a self-administered questionnaire and ambulance dispatch records during November 2017. We performed multiple logistic regression; in total, 254 ambulance staff were eligible for inclusion in the analysis. The adjusted odds of near-miss incidents were 3.19 times higher for participants with higher fatigue than for those with normal fatigue, with statistical significance. Fatigue was significantly associated with the monthly number of ambulance dispatches, office working hours, mealtimes, daytime napping hours, and napping hours during a night shift. In this study, we demonstrated a positive association between fatigue and near-miss incidents among ambulance personnel. Additionally, our results suggest that irregular lifestyles are a root cause of fatigue in ambulance personnel.

Relationship between the depressive state of emergency life-saving technicians and near-misses.

AIM: A depressive state is a key risk factor for medical errors made by emergency life-saving technicians (ELSTs). However, no study has examined the occurrence of near-misses in ELSTs. We investigated the association between a depressive state and near-misses among ELSTs. METHODS: A cross-sectional study was undertaken in 345 ELSTs using an anonymous self-administered questionnaire. The main exposure was a depressive state that was measured using the Quick Inventory of Depressive Symptomatology. For the main outcome, near-miss events, we calculated odds ratios (OR) of depressive states, adjusted for age and work-related factors by multivariable logistic regression. For exploratory purposes, we also undertook secondary analyses to determine whether work-related factors were associated with a depressive state. RESULTS: We obtained 254 responses. Compared to ELSTs without a depressive state, the adjusted OR for near-misses among ELSTs with a mild depressive state was 3.14 (95% confidence interval [CI], 1.37-7.16; P = 0.007), and that among ELSTs with a moderate or greater depressive state was 5.29 (95% CI, 1.46-19.09; P = 0.011). For a depressive state, in the exploratory analyses, the OR of nap duration while on duty for less than 2 h was 3.34 (95% CI, 1.15-9.67; P = 0.027), that for irregular mealtime while on duty was 3.71 (95% CI, 2.00-6.86; P < 0.001), and that for a duration of desk work of 4 h or longer was 2.21 (95% CI, 1.15-4.25; P = 0.017). CONCLUSION: A depressive state was significantly associated with the occurrence of near-misses among ELSTs. That a depressive state among ELSTs was related to nap duration and excessive office work indicates that improved management of the work environment and operations of ELSTs is necessary for the provision of safe emergency medical services.

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.

Predictability of the Call Triage Protocol to Detect if Dispatchers Should Activate Community First Responders.

INTRODUCTION: Shortening response time to an emergency call leads to the success of resuscitation by chest compression and defibrillation. However, response by ambulance or fire truck is not fast enough for resuscitation in Japan. In rural areas, response times can be more than 10 minutes. One possible way to shorten the response time is to establish a system of first responders (eg, police officers or firefighters) who are trained appropriately to perform resuscitation. Another possible way is to use a system of Community First Responders (CFRs) who are trained neighbors. At present, there are no call triage protocols to decide if dispatchers should activate CFRs. OBJECTIVE: The aim of this study was to determine the predictability to detect if dispatchers should activate CFRs. METHODS: Two CFR call triage protocols (CFR protocol Ver.0 and Ver.1) were established. The predictability of CFR protocols was examined by comparing the paramedic field reports. From the results of sensitivity of CFR protocol, the numbers of annual CFR activations were calculated. All data were collected, prospectively, for four months from October 1, 2012 through January 31, 2013. RESULTS: The ROC-AUC values appear slightly higher in CFR protocol Ver.1 (0.857; 95% CI, 79.8-91.7) than in CFR protocol Ver.0 (0.847; 95% CI, 79.0-90.3). The number of annual CFR activations is higher in CFR protocol Ver.0 (7.47) than in CFR protocol Ver.1 (5.45). CONCLUSION: Two call triage protocols have almost the same predictability as the Medical Priority Dispatch System (MPDS). The study indicates that CFR protocol Ver.1 is better than CFR protocol Ver.0 because of the higher predictability and low number of activations. Also, it indicates that CFRs who are not medical professionals can respond to a patient with cardiac arrest.

Development of a first-responder dispatch system using a smartphone.

We constructed a prototype community first responder (CFR) dispatch system. The system sends incident information, including a map, to the chosen CFR's mobile phone. We tested it in a simulation of 30 out-of-hospital cardiac arrest incidents which had occurred in the town of Motegi during the previous year. Thirty off-duty firefighters acted as CFRs and were sent to the same locations. The mean response time (from the CFR receiving dispatch information to arrival at the scene) was 3 min 37s faster than the actual response time in the corresponding historical control, i.e. the response time was reduced by 36% (P < 0.01). The median travel distance of the CFRs was 3.4 km and there was a positive correlation between response time and travel distance. The study showed that interactive communication between dispatcher and CFR was important for effective operation and that CFRs could reach an OHCA patient before the Emergency Medical Service arrives.

Introduction of the community first responder system into Japan: is that possible?

BACKGROUND: To improve out-of-hospital cardiac arrest (OHCA) survival rates in Japan, implementation of a community first responder (CFR) system is considered one of the most effective emergency medical service options. We investigated the possibility of introducing a CFR system in Japan. METHODS: Cross-sectional surveys were given to 1,350 residents over the age of 18 who were selected from resident registration lists in Tochigi prefecture. Residents were questioned whether they would agree to have a CFR system in their community and whether they would participate as a responder. Positive attitudes about the cross-sectional study led us to conduct pilot CFR trials. Trials were conducted in rural areas of Tochigi prefecture by local EMS personnel. We were able to discuss and develop CFR introduction guidelines for Japanese communities using the results of the individual surveys, pilot trials, and other countries' guidelines. Finally, our CFR system, which referred to developed CFR introduction guidelines, was introduced into Ishikawa prefecture's Shioya town (population of 710). RESULTS: A total of 92.5% of Tochigi residents either strongly agreed or agreed to have a CFR system in their community, and 16.7% of Tochigi's residents chose to participate. The two CFR introduction prerequisites were identified as: (1) an information delivery system for CFR and (2) budget preparation. CFR introduction guidelines were developed, and a CFR system was introduced in Shioya town on 4 November 2012 with 32 participants. On 1 January 2013, a CFR responded for the first time, and the CFR system worked efficiently. CONCLUSIONS: By providing information about the CFR system to the community and preparing several infrastructural elements, it was possible to introduce and operate a successful CFR system in Japan.

Muscles used for chest compression under static and transportation conditions.

BACKGROUND: Unstable conditions during ambulance transportation are not conducive to the performance of high-quality cardiopulmonary resuscitation by emergency medical technicians. OBJECTIVE: The present study was conducted to clarify differences in the quality of chest compression and associated muscle activity between static and ambulance transportation conditions. METHODS: Nine paramedic students performed chest compression for 5 minutes on the floor and during ambulance transportation. Compression rate and depth and success and error rates of chest compression were determined using the Resusci Anne manikin with a PC SkillReporting System (Laerdal Medical). Integrated electromyography (i-EMG) values of eight different muscles were also recorded bilaterally during the first and last 30 seconds of compression. RESULTS: There was no significant difference in compression rate per minute (p = 0.232) and depth of chest compression (p = 0.174) between the two conditions. The success rate was significantly lower under the ambulance transportation condition than under the static condition (p = 0.0161). Compared with those under the static condition, the total i-EMG values were significantly lower for the multifidus (p = 0.0072) and biceps femoris (p < 0.0001) muscles and significantly higher for the deltoid (p = 0.0032), pectoralis major (p = 0.0037), triceps brachii (p = 0.0014), vastus lateralis (p < 0.0001), and gastrocnemius (p = 0.0004) muscles under the ambulance transportation condition. CONCLUSIONS: Chest compression is performed mainly through flexion and extension of the hip joint while kneeling on the floor and through the elbow and shoulder joints while standing in a moving ambulance. Therefore, the low quality of chest compression during ambulance transportation may be attributable to an altered technique of performing the procedure.
