Background:
The recent United States (US) troop withdrawal out of Afghanistan under a February 2020 US-Taliban agreement and the rapid concurrent collapse of the Afghan military, followed by the ascendance of the Taliban, has placed an international spotlight around the future of South Asian countries. Security threats, in particular, will likely escalate within the region and beyond, with significant concerns around the resurgence of terrorism and violence in the region. This study aims to provide an epidemiological description of all terrorism-related attacks in South Asia sustained from 1970 – 2019. These data will be useful in the development of education programs in Counter-Terrorism Medicine and provide an insight into potential attacks in the future.
Methods:Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all events which occurred in Afghanistan, Bangladesh, Bhutan, India, Maldives, Mauritius, Nepal, Pakistan, and Sri Lanka (collectively referred to as South Asia) from January 1, 1970 - December 31, 2019. Primary weapon type, primary target type, country where the incident occurred, and number of deaths and injuries were collated and exported for analysis.
Results:In total, 23.69% of all terrorist attacks from 1970-2019 occurred in the South Asia region, causing 96,092 deaths and 141,333 non-fatal injuries. Of those, 50.1% of attacks in South Asia used explosives, 31.9% used firearms, 9.4% used unknown weapons, 5.9% used incendiary attacks, 2.3% were melee attacks, and <0.5% used chemical, biological, and other weapon types.
Conclusion:Over 88% of the attacks occurred in Afghanistan, Pakistan, and India combined. While there has been a decline in attacks since a peak in 2014, there are concerns of a significant increase in terrorism activity in recent months which could impact an already fragmented health care system. The use of explosives and firearms as attack modalities accounted for 82.0 % of all weapon types used, but the impact of terrorism and conflict expands beyond simple death and casualty tolls.

Introduction:
The majority of pediatric medications are dosed according to weight and therefore accurate weight assessment is essential. However, this can be difficult in the unpredictable and peripatetic prehospital care setting, and medication errors are common. The Handtevy method and the Broselow tape are two systems designed to guide Emergency Medical Services (EMS) providers in both pediatric patient weight estimation and medication dosing. The accuracy of the Handtevy method of weight estimation as practiced in the field by EMS has not been previously examined.
Study Objective:The primary objective of this study was to examine the field performance of the Handtevy method and the Broselow tape with respect to prehospital patient weight estimation.
Methods:This was a retrospective chart review of trauma and non-trauma patients transported by EMS to the emergency department (ED) of a quaternary care children’s hospital from January 1, 2021 through June 30, 2021. Demographic data, ED visit information, prehospital weight estimation, and medication dosing were collected and analyzed. Scale-based weight from the ED was used as the standard for comparison.
Results:A total of 509 patients <13 years of age were included in this study. The EMS providers using the Broselow method estimated patient weight to within +/-10% of ED scale weight in 51.3% of patients. When using the Handtevy method, the EMS providers estimated patient weight to within +/-10% of ED scale weight in 43.7% of patients. When comparing the Handtevy versus Broselow method of prehospital weight estimation, there was no significant association between method and categorized weight discrepancy (over, under, or accurate estimates – defined as within 10% of ED scale weight; P = .25) or percent weight discrepancy (P = .75). On average, prehospital weight estimation was 6.33% lower than ED weight with use of the Handtevy method and 6.94% lower with use of the Broselow method.
Conclusion:This study demonstrated no statistically significant difference between the use of the Handtevy or Broselow methods with respect to prehospital weight estimation. While further research is necessary, these results suggest similar field performance of the Broselow and Handtevy methods.

Introduction:
Over the past five decades, Eastern Europe has seen relatively little in terms of terrorist attacks. The recent escalation of the Russo-Ukrainian conflict has, however, placed a new spotlight on the region, and new questions and concerns around war, conflict, insurgency, and terrorism are being posed. The Russian invasion and extensive combat operations, the largest in Europe since World War II, are occurring across Ukraine where there are 15 active nuclear reactors, not including the Chernobyl site, that are vulnerable to attack or sabotage. In addition, Eastern Europe has been heavily affected by COVID-19, exposing broad vulnerabilities in an otherwise fragile health care system. This raises concerns over the ability of Eastern European health care institutions to absorb surge and manage terrorist attacks or acts of violent extremism. This study provides an epidemiological description of all terrorism-related fatalities and injuries in Eastern Europe sustained from 1970 – 2019.
Method:Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database functions for all terrorism events which occurred in Eastern Europe from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of this study. Primary weapon type, country where the incident occurred, and number of deaths and injured were collated. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.
Results:There were 3,901 terrorism-related events in Eastern Europe between the years 1970 and 2019, inclusive. In total, the attacks resulted in 5,391 deaths and 9,538 persons injured. Explosives were the most commonly used weapon type in 59.2% of all attacks in the region, followed by firearms in 27.6%.
Conclusion:From 1970 through 2019, a total of 3,901 terrorist attacks occurred in Eastern Europe, inflicting 5,391 deaths and 9,538 injuries. Of those, 72.3% occurred in Russia and Ukraine. Terrorist attacks sharply declined since the peak in 2014, but there is an overall uptrend in attacks since the 1970s.

Background/Introduction:
Papua New Guinea (PNG) is a Pacific nation of over nine million. It is one of the world’s most diverse nations, with over 800 languages and geographic diversity that includes both tropical islands and highland mountains. Located on the Pacific “ring of fire,” PNG is regularly struck by disasters and outbreaks. The COVID-19 pandemic triggered multiple deployments of international EMTs to PNG, which were coordinated through a national EMT Coordination Cell. To strengthen rapid, national response to future emergencies, the PNG Government through its National Department of Health is now developing the “PNG EMT.”
Objectives:To describe the development of the PNG EMT.
Method/Description:PNG’s national EMT development was inspired by multiple international EMT deployments, including the 2018 Highlands earthquake and multiple COVID-19 deployments. With support from WHO, PNG’s National Department of Health led EMT coordination efforts in those responses, and recognized the need for similar capabilities to be developed for national response.
Results/Outcomes:To develop the PNG EMT, a focal point was appointed, a national technical working group was formed, and SOPs have been drafted with support from WHO and partners. In consultation with PNG and other Pacific EMTs, WHO is procuring a tailored Pacific EMT cache, including items specifically selected for PNG’s diverse geographic and climactic environments. PNG plans to train team members and be ready for self-sufficient national deployments by late 2022.
Conclusion:PNG is strengthening readiness for future emergencies by developing a national EMT capable of rapid response to challenging and austere post-disaster environments.

Background:
The rapid popularization of unmanned aerial vehicles (UAVs; also referred to as drones), in both the recreational and industrial sectors, has paved the way for rapid developments in drone capabilities. Although the threat of UAVs used by terrorists has been recognized by specialists in both Counter-Terrorism and Counter-Terrorism Medicine (CTM), there are limited data on the extent and characteristics of drone use by terrorist organizations.
Methods:Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all terrorist attacks using UAVs from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of the study. Primary weapon type, number and type of UAVs used, related attacks, location (country, world region), and number of deaths and injuries were collated. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.
Results:There were 76 terrorist attacks using UAVs. The first attack occurred in 2016, and the number of attacks per year varied considerably (range: 4-36). Forty-seven of the 76 attacks (70%) were successful. Twenty-seven individually listed events (36%) were related and part of nine coordinated, multi-part incidents. A total of 50 deaths and 132 injuries were recorded, which equated to 1.09 deaths (range: 0-6) and 2.89 injuries (range: 0-20) per successful attack. The mean number of UAVs used in an attack was 1.28 (range: 1-5) and multiple UAVs were used in 22% of attacks.
Conclusion:The use of UAVs to carry out terrorist attacks is on the rise. Seventy-six terrorist attacks using this novel method were recorded since 2016, killing 50 and injuring 132 people. While the use of UAV-related explosives appears less lethal than traditional explosive attacks, advancing technologies and swarming capabilities, increasing ability to carry larger payloads, and the possibility of UAVs to disperse chemical, biological, radiological, and nuclear (CBRN) weapons will likely increase UAV lethality in the future, requiring CTM specialists be more proactive.

Background:
Tracheal intubation is a high-risk intervention for exposure to airborne infective pathogens, including the novel coronavirus disease 2019 (COVID-19). During the recent pandemic, personal protective equipment (PPE) was essential to protect staff during intubation but is recognized to make the practical conduct of anesthesia and intubation more difficult. In the early phase of the coronavirus pandemic, some simple alterations were made to the emergency anesthesia standard operating procedure (SOP) of a prehospital critical care service to attempt to maintain high intubation success rates despite the challenges posed by wearing PPE. This retrospective observational cohort study aims to compare first-pass intubation success rates before and after the introduction of PPE and an altered SOP.
Methodology:A retrospective observational cohort study was conducted from January 1, 2019 through August 30, 2021. The retrospective analysis used prospectively collected data using prehospital electronic patient records. Anonymized data were held in Excel (v16.54) and analyzed using IBM SPSS Statistics (v28). Patient inclusion criteria were those of all ages who received a primary tracheal intubation attempt outside the hospital by critical care teams. March 27, 2020 was the date from which the SOP changed to mandatory COVID-19 SOP including Level 3 PPE – this date is used to separate the cohort groups.
Results:Data were analyzed from 1,266 patients who received primary intubations by the service. The overall first-pass intubation success rate was 89.7% and the overall intubation success rate was 99.9%. There was no statistically significant difference in first-pass success rate between the two groups: 90.3% in the pre-COVID-19 group (n = 546) and 89.3% in the COVID-19 group (n = 720); Pearson chi-square 0.329; P = .566. In addition, there was no statistical difference in overall intubation success rate between groups: 99.8% in the pre-COVID-19 group and 100.0% in the COVID-19 group; Pearson chi-square 1.32; P = .251.
Non-drug-assisted intubations were more than twice as likely to require multiple attempts in both the pre-COVID-19 group (n = 546; OR = 2.15; 95% CI, 1.19-3.90; P = .01) and in the COVID-19 group (n = 720; OR = 2.5; 95% CI, 1.5-4.1; P = <.001).
Conclusion:This study presents simple changes to a prehospital intubation SOP in response to COVID-19 which included mandatory use of PPE, the first intubator always being the most experienced clinician, and routine first use of video laryngoscopy (VL). These changes allowed protection of the clinical team while successfully maintaining the first-pass and overall success rates for prehospital tracheal intubation.

Introduction:
Hospitalized neonates are vulnerable to natural and man-made disasters because of their persistent requirement for medical resources and may need to be evacuated to safe locations when electricity and medical gas supply become unreliable. In Japan, a triage system for hospitalized neonates, or the Simple Triage and Rapid Treatment for Neonates, Revised (START-Neo-R), has been used to determine whether neonates are in suitable conditions for transportation. However, this scale is not useful to determine the evacuation order of neonates because a considerable number of evacuees are classified into the same categories.
Study Objective:To solve this problem, a novel triage system, Neonatal Extrication Triage (NEXT) was developed. This study tested the validity and reproducibility of both triages and compared them with a standardized prognostic scoring system for hospitalized neonates, the Neonatal Therapeutic Intervention Scoring System (NTISS).
Methods:In this retrospective observational study, physicians and nurses independently assessed each neonate hospitalized at a tertiary neonatal intensive care unit (NICU) twice weekly using NEXT and START-Neo-R. The NEXT system comprises six questionnaires regarding medical resources required during transition and transportation, providing composite scores on a 12-point scale. The START-Neo-R classified neonates into five levels based on the severity of disease and dependence on medical care. Inter-rater reliability of both systems was assessed using Cohen’s kappa coefficient, whereas the criterion validity with NTISS was assessed using Spearman’s correlation coefficient.
Results:Overall, 162 neonates were assessed for 49 days, resulting in triage data for 1,079 accumulated patients. Both NEXT scores and START-Neo-R ranks were well-dispersed across different levels without excessive accumulation in specific categories. Inter-rater reliability of NEXT (kappa coefficient, 0.973; 95% confidence interval, 0.969-0.976) and START-Neo-R (kappa coefficient, 0.952; 95% confidence interval, 0.946-0.957) between physicians and nurses was sufficiently high. The correlation coefficient of NEXT and START-Neo-R scores with NTISS scores were 0.889 (P <.001) and 0.850 (P <.001), respectively.
Conclusions:Both START-Neo-R and NEXT had good reproducibility and correlation with the severity of neonates indicated by NTISS. With its well-dispersed scores across different levels, the NEXT system might be a powerful tool to determine the priority of evacuation objectively.

Introduction:
The management of out-of-hospital traumatic cardiac arrest (TCA) for professional rescuers entails Advanced Life Support (ALS) with specific actions to treat the potential reversible causes of the arrest: hypovolemia, hypoxemia, tension pneumothorax (TPx), and tamponade. The aim of this study was to assess the impact of specific rescue measures on short-term outcomes in the context of resuscitating patients with a TCA.
Methods:This retrospective study concerns all TCA patients treated in two emergency medical units, which are part of the Northern French Alps Emergency Network (RENAU), from January 2004 through December 2017. Utstein variables and specific rescue measures in TCA were compiled: fluid expansion, pelvic stabilization, tourniquet application, bilateral thoracostomy, and thoracotomy procedures. The primary endpoint was survival rate at Day 30 with good neurological status (Cerebral Performance Category [CPC] score CPC 1 and CPC 2).
Results:In total, 287 resuscitation attempts in TCA were included and 279 specific interventions were identified: 262 fluid expansions, 41 pelvic stabilizations, five tourniquets, and 175 bilateral thoracostomies (including 44 with TPx).
Conclusion:Among the standard resuscitation measures to treat the reversible causes of cardiac arrest, this study found that bilateral thoracostomy and tourniquet application on a limb hemorrhage improve survival in TCA. A larger sample for pelvic stabilization is needed.

Introduction and Objective:
Acute gastroenteritis (AGE) is one of the most common clinical diagnoses globally, and dehydration in severe AGE cases can cause severe morbidity and mortality. Depending on the metabolic acidosis that occurs in dehydration, the respiratory rate per minute is increased, and the carbon dioxide pressure in the arterial blood is decreased. This condition correlates with end-tidal carbon dioxide (ETCO2). Therefore, this study primarily aims to evaluate whether ETCO2 measurement has a role in detecting metabolic fluid deficit, dehydration level, and regression in dehydration level after fluid replacement and its correlation with Vena Cava Collapsibility Index (VCCI).
Material and Method:This study included spontaneously breathing patients admitted to the emergency department of a tertiary training and research hospital with symptoms of AGE and were thought to be moderately (6.0%-9.0%) and severely (>10.0%) dehydrated according to the Primary Options of Acute Care (POAC) Clinical Dehydration Scale. After the first evaluation, the patients’ vital signs, ETCO2 values, diameters of the inferior vena cava (IVC) in inspiration and expiration, and VCCI were measured and recorded. These measurements were repeated after intravenous (IV) fluid replacement, and finally, a comparison was made between the measurements.
Results:A total of 49 patients, as 16 male (32.7%) and 33 female (67.3%), were included in the study. The mean fluid replacement value was calculated as 664.29 (SD = 259.41) ml. The mean increase in ETCO2 was 3.653 (SD = 2.554) mmHg (P <.001). The mean increase in inferior vena cava expirium (IVCexp) was calculated as 0.402 (SD = 0.280) cm (P <.001) and the mean increase in inferior vena cava inspirium (IVCinsp) as 0.476 (SD = 0.306) cm (P <.001). The VCCI (%) decreased by 12.556 (SD = 13.683) (P <.001). Post-replacement vital signs, ETCO2, and VCCI correlations of the patients were examined and no significant correlation was found between ETCO2 and VCCI (%). As a result of this study, a receiver operating characteristic (ROC) curve was established for the ETCO2 values predicting the level of dehydration and fluid response, and the area under the curve was calculated as 0.748. However, to classify the patient as moderately dehydrated, the ETCO2 cutoff value was determined as 28.5mmHg.
Conclusion:The sensitivity and specificity of ETCO2 levels were 71.43% and 74.29% in evaluating the level of dehydration, and no correlation was found with VCCI, which is known to have high sensitivity and specificity in previous studies in determining the level of dehydration and fluid response. Hence, VCCI measurement made through ultrasonography (USG) is a method that should be preferred more in determining the level of dehydration. Nevertheless, as per the results of this study, swift ETCO2 measurements may be helpful in monitoring the change in the degree of dehydration with treatment in patients who were admitted to the emergency department with dehydration findings and were administered IV fluid replacement therapy.

Objective:
Cricothyroidotomy is an advanced airway procedure for critically ill or injured patients. In Victoria, Australia, intensive care paramedics (ICPs) perform needle cricothyroidotomy utilizing the proprietary QuickTrach II (QTII) device. Recently, an Ambulance Victoria (AV) institutional change in workflow included pre-puncture surgical incision to assist in successful placement. This review aims to explore whether a surgical pre-incision prior to the insertion of the device improved overall procedural success rates of needle cricothyroidotomy using the QTII.
Methods:This was a retrospective review of all patients who received a needle cricothyroidotomy by ICPs from May 1, 2015 through September 15, 2020. Data and patient care records were sourced from the AV data warehouse.
Results:A total of 27 patients underwent a needle cricothyroidotomy with the mean age of patients being 50.2 years. Most cricothyroidotomies were performed using the QuickTrach II kit (92.6%). Prior to modification of the QTII procedure, front-of-neck access (FONA) success was 50.0%; however, this improved to 82.4% after the procedures recent update. The overall success rate of all paramedic-performed needle cricothyroidotomy during the study period was 74.1% (n = 20).
Conclusions:This review demonstrates that propriety devices such as the QTII device achieve a low success rate for a FONA intervention. Despite the low frequency of this procedure, ICPs with extensive training and regular maintenance can perform needle cricothyroidotomy using scalpel assistance with a reasonable success rate. But when compared to the broader literature, success rate using a more straightforward technique such as a surgical cricothyroidotomy technique is likely going to be higher.

Introduction:
Placing peripheral intravenous catheters (“IV lines”) is a standard procedure for health care professionals in acute and emergency medicine. The study aimed to determine the learning curve and success rates in applying IV lines during a three-year paramedic training and the factors influencing successful placement.
Methods:This was a prospective and noninterventional observational study to determine the influencing factors, learning outcomes, and performance in the placement of IV lines by trainees and experienced paramedics. Trial registration: German Clinical Trials Register, ID DRKS00024631.
Results:From February 1, 2016 through December 31, 2021, a total of 3,547 peripheral venous accesses attempts were performed: 76.5% (n = 2,712) by trainees and 23.5% (n = 835) by experienced practitioners. The trainee group had one-to-three years of training and the experienced group had 11 (SD = 11) years of work experience after training (one-to-35 years). The learning or success curve in the successful placement of peripheral venous accesses was 85.2% in the first year of training, 88.5% in the second year of training, and 92.5% in the third year (and the end of training). It was then 94.3% in the fourth year (first year of being experienced). Successful insertion of peripheral venous accesses in the experienced group was up to 97.0%. The first-attempt success rate was 90.4% across the entire trainee group versus 95.9% in the experienced group (P <.0001).
Significant factors influencing successful placement of IV lines were puncture site (P = .022), catheter size (OR = 0.600; P = .002), and number of attempts (OR = 0.370; P <.001). The time of day (or night) was not influential. Work experience, patient age, or blood pressure were also not significant.

Objectives:
Studies have demonstrated the efficacy of mechanical devices at delivering high-quality cardiopulmonary resuscitation (HQ-CPR) in various transport settings. Herein, this study investigates the efficacy of manual and mechanical HQ-CPR delivery on a fire rescue boat.
Methods:A total of 15 active firefighter-paramedics were recruited for a prospective manikin-based trial. Each paramedic performed two minutes manual compression-only CPR while navigating on a river-based fire rescue boat. The boat was piloted in either a stable linear manner or dynamic S-turn manner to simulate obstacle avoidance. For each session of manual HQ-CPR, a session of mechanical HQ-CPR was also performed with a LUCAS 3 (Stryker; Kalamazoo, Michigan USA). A total of 60 sessions were completed. Parameters recorded included compression fraction (CF) and the percentage of compressions with correct depth >5cm (D%), correct rate 100-120 (R%), full release (FR%), and correct hand position (HP%). A composite HQ-CPR score was calculated as follows: ((D% + R% + FR% + HP%)/4) * CF%). Differences in magnitude of change seen in stable versus dynamic navigation within study conditions were evaluated with a Z-score calculation. Difficulty of HQ-CPR delivery was assessed utilizing the Borg Rating of Perceived Exertion Scale.
Results:Participants were mostly male and had a median experience of 20 years. Manual HQ-CPR delivered during stable navigation out-performed manual HQ-CPR delivered during dynamic navigation for composite score and trended towards superiority for FR% and R%. There was no difference seen for any measured variable when comparing mechanical HQ-CPR delivered during stable navigation versus dynamic navigation. Mechanical HQ-CPR out-performed manual HQ-CPR during both stable and dynamic navigation in terms of composite score, FR%, and R%. Z-score calculation demonstrated that manual HQ-CPR delivery was significantly more affected by drive style than mechanical HQ-CPR delivery in terms of composite HQ-CPR score and trended towards significance for FR% and R%. Borg Rating of Perceived Exertion was higher for manual CPR delivered during dynamic sessions than for stable sessions.
Conclusion:Mechanical HQ-CPR delivery is superior to manual HQ-CPR delivery during both stable and dynamic riverine navigation. Whereas manual HQ-CPR delivery was worse during dynamic transportation conditions compared to stable transport conditions, mechanical HQ-CPR delivery was unaffected by drive style. This suggests the utility of routine use of mechanical HQ-CPR devices in the riverine patient transport setting.

Introduction:
Mass-casualty incidents (MCIs) are events in which many people are injured during the same period of time. This has major implications in regards to practical concerns and planning for both personnel and medical equipment. Smart glasses are modern tools that could help Emergency Medical Services (EMS) in the estimation of the number of potential patients in an MCI. However, currently there is no study regarding the advantage of employing the use of smart glasses in MCIs in Thailand.
Study Objective:This study aims to compare the overall accuracy and amount of time used with smart glasses and comparing it to manual counting to assess the number of casualties from the scene.
Methods:This study was a randomized controlled trial, field exercise experimental study in the EMS unit of Srinagarind Hospital, Thailand. The participants were divided into two groups (those with smart glasses and those doing manual counting). On the days of the simulation (February 25 and 26, 2022), the participants in the smart glasses group received a 30-minute training session on the use of the smart glasses. After that, both groups of participants counted the number of casualties on the simulation field independently.
Results:Sixty-eight participants were examined, and in the smart glasses group, a total of 58.8% (N = 20) of the participants were male. The mean age in this group was 39.4 years old. The most experienced in the EMS smart glasses group had worked in this position for four-to-six years (44.1%). The participants in the smart glasses group had the highest scores in accurately assessing the number of casualties being between 21-30 (98.0%) compared with the manual counting group (89.2%). Additionally, the time used for assessing the number of casualties in the smart glasses group was shorter than the manual counting group in tallying the number of casualties between 11-20 (6.3 versus 11.2 seconds; P = .04) and between 21-30 (22.1 versus 44.5 seconds; P = .02).
Conclusion:The use of smart glasses to assess the number of casualties in MCIs when the number of patients is between 11 and 30 is useful in terms of greater accuracy and less time being spent than with manual counting.

Objective:
Iatrogenic tracheal rupture is an unusual and severe complication that can be caused by tracheal intubation. The frequency, management, and outcome of iatrogenic tracheal rupture due to prehospital emergency intubation in adults by emergency response physicians has not yet been sufficiently explored.
Methods:Adult patients with iatrogenic tracheal ruptures due to prehospital emergency intubation admitted to an academic referral center over a 15-year period (2004-2018) with consideration of individual risk factors were analyzed.
Results:Thirteen patients (eight female) with a mean age of 67 years met the inclusion criteria and were analyzed. Of these, eight tracheal ruptures (62%) were caused during the airway management of cardiopulmonary resuscitation (CPR). Stylet use and difficult laryngoscopy requiring multiple attempts were documented in eight cases (62%) and four cases (30%), respectively. Seven patients (54%) underwent surgery, while six patients (46%) were treated conservatively. The overall 30-day mortality was 46%; five patients died due to their underlying emergencies and one patient died of tracheal rupture. Three survivors (23%) recovered with severe neurological sequelae and four (30%) were discharged in good neurological condition. Survivors had significantly smaller mean rupture sizes (2.7cm versus 6.3cm; P <.001) and less cutaneous emphysema (n = 2 versus n = 6; P = .021) than nonsurvivors.
Conclusions:Iatrogenic tracheal rupture due to prehospital emergency intubation is a rare complication. Published risk factors are not consistently present and may not be applicable to identify patients at high risk, especially not in rescue situations. Treatment options depend on individual patient condition, whereas outcome largely depends on the underlying disease and rupture extension.

Background:
Mass-casualty incidents (MCIs) and disasters are characterized by a high heterogeneity of effects and may pose important logistic challenges that could hamper the emergency rescue operations.
The main objective of this study was to establish the most frequent logistic challenges (red flags) observed in a series of Italian disasters with a problem-based approach and to verify if the 80-20 rule of the Pareto principle is respected.
Methods:A series of 138 major events from 1944 through 2020 with a Disaster Severity Score (DSS) ≥ four and five or more victims were analyzed for the presence of twelve pre-determined red flags.
A Pareto graph was built considering the most frequently observed red flags, and eventual correlations between the number of red flags and the components of the DSS were investigated.
Results:Eight out of twelve red flags covered 80% of the events, therefore not respecting the 80-20 rule; the number of red flags showed a low positive correlation with most of the components of the DSS score. The Pareto analysis showed that potential hazards, casualty nest area > 2.5km2, number of victims over 50, evacuation noria over 20km, number of nests > five, need for extrication, complex access to victims, and complex nest development were the most frequently observed red flags.
Conclusions:Logistic problems observed in MCIs and disaster scenarios do not follow the 80-20 Pareto rule; this demands for careful and early evaluation of different logistic red flags to appropriately tailor the rescue response.

Background/Introduction:
The COVID-19 pandemic resulted in multiple requests for EMT assistance in the Pacific Region. AUSMAT responded in six countries, sometimes simultaneously. The needs of the pandemic and the pressures on available resources to respond required development of innovative methods. One example is the “POP-O-MOP” tool.
Objectives:Describe the evolution and utility of “POP-O-MOP” tool in building local capacity in Pacific health care systems facing COVID-19 outbreaks.
Method/Description:The initial aim of the tool was to assist in maximizing the response by providing a concise, one-page teaching tool to assist in training of local nursing staff. As the tool evolved over successive COVID-19 deployments in the Pacific Region, the scope grew to include medical and allied health staff, and the content was refined.
While the “POP-O-MOP” mnemonic provides an aide-memoir for steps of COVID-19 care at the bedside; it also provided a structure for facilitating training and interdisciplinary discussion amongst clinicians.
Results/Outcomes:By utilizing this structured training face-to-face, video, and online formats, the number of staff able to treat COVID-19 patients was increased, drawing on novices and staff from non-critical care backgrounds.
Of significance, it was observed that while the technical skills included improved health response, the confidence gained by local staff in the brief training increased their desire to contribute to the COVID-19 response by overcoming stigma, fear, and the sense of futility.
Conclusion:The POP-O-MOP tool proved to be an effective tool to leverage in-country resources by providing effective just-in-time training for local health care workers.

Introduction:
Stingray envenomation is a marine injury suffered by ocean goers throughout the world. No prospective studies exist on the various outcomes associated with these injuries.
Study Objective:The aim of this study was to perform a prospective, observational study of human stingray injuries to determine the natural history, acute and subacute complications, prevalence of medical evaluation, and categories of medical treatment.
Methods:This study prospectively studied a population of subjects who were injured by stingrays at Seal Beach, California (USA) from July 2012 through September 2016 and did not immediately seek emergency department evaluation. Subjects described their initial injury and provided information on their symptoms, medical evaluations, and medical treatment for the injury at one week and one month after the injury. This information was reported as descriptive statistics.
Results:A total of 393 participants were enrolled in the study; 313 (80%) of those completed the one-week follow-up interview and 279 (71%) participants completed both the one-week and one-month follow-up interviews. Overall, 234 (75%) injuries occurred to the foot. One hundred sixty-three (52%) patients had complete resolution of their pain within one week and 261 (94%) had either complete resolution or improvement of pain by one month. Sixty-eight (22%) subjects reported being evaluated by a physician and a total of 49 (17%) subjects reported antibiotic treatment for their wound. None of the subjects required parenteral antibiotics or hospital admission.
Conclusion:The majority of stingray victims recover from stingray injury without requiring antibiotics. A subset of subjects will have on-going wound pain after one month. The need for parenteral antibiotics or hospital admission is rare.

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.

Introduction:
Prehospital ultrasounds can be considered a new form of diagnostic tool when taking into account their small structure and due to the fact that nowadays, they are used in the care of emergency patients. However, at present, there is no study regarding the advantage of ultrasound usage in prehospital settings in Thailand.
Study Objective:This study aims to determine the sonographic characteristics recorded by handheld ultrasounds used in prehospital care and the diagnostic accuracy of ultrasounds for prehospital patients.
Methods:A cross-sectional study was conducted on prehospital patients who underwent point-of-care ultrasound (POCUS) examination on Emergency Medical Service (EMS) operations at Srinagarind Hospital, Thailand from January 2021 through December 2021. The ultrasound images, the electronic emergency department medical records, and the EMS database were recorded and reviewed by a team of emergency physicians. The quality of prehospital ultrasound examinations was assessed by comparing the diagnoses at the scene with those taken at the hospital.
Results:One hundred sixty-nine prehospital patients who received POCUS examinations were examined over a one-year period. All (100.0%) of the scans were for medical cases. No ultrasound protocol was used in the prehospital care. Two hundred eight POCUS examinations were performed in this study. The most common POCUS indication was dyspnea (45.6%), followed by hypotension/shock (30.1%), and finally syncope (8.2%). The most common area where POCUS was performed was on the lung (37.0%), followed by the inferior vena cava (30.8%), and finally for cardiac cases (26.4%). This study found that 34.9% of sonographic findings could be considered abnormal. The diagnoses of prehospital patients were confirmed by using POCUS in 66 cases (39.1%) with the accuracy of prehospital diagnosis reaching a peak of 75.8%.
Conclusion:This study shows POCUS examinations can be effectively used in prehospital care. The prehospital diagnosis given by physicians administering treatment who used POCUS examinations correlated with the in-hospital diagnosis.

Background/Introduction:
During health emergencies, significant disruptions occur concurrently within critical components of acute care systems such as workforce, medical supplies, clinical workflows, patient care pathways, and hospital essential support services. The ability to map both existing and surge capacities across the acute care health system is a complex, nuanced, and often lengthy process which is heavily dependent upon localized knowledge applied in specific, individual contexts.
Objectives:Outline an innovative, “All Hazards” tool developed through a standardized framework approach to rapidly and consistently identify, assess, and prioritize key system-wide health capacity indicators in acute care hospital settings during health emergencies.
Method/Description:Initially designed as a health systems preparedness and planning tool for use in sudden-onset disasters in 2017, the “7S” framework has been successfully applied during recent AUSMAT outbreak emergency responses to assist local Ministries of Health to effectively identify, articulate, rationalize, and prioritize clinical and operational health response priorities.
Results/Outcomes:Multiple operational health leaders found the “7S” framework valuable in efficiently managing both the assessment of and priority allocation of resources in health systems under duress. The tool was simple to understand and explain, time efficient, and comprehensive. Additionally, the tool provided an effective structure for communicating with local health and response leaders.
Conclusion:The “7S” framework has demonstrated excellent utility as a highly effective and scalable, locally adapted “All Hazards” tool for use during health planning, preparedness, and acute care response phases in diverse health emergencies contexts.
