Norwegian Open Fracture Management System: Outcomes After 10 Years Working in Low-Resource Settings in Cambodian Hospitals

Introduction: The treatment of open lower limb fractures represents a major challenge for any trauma surgeon, and this even more so in resource-limited areas. The aim of the study is to describe the intervention, report the treatment plan, and observe the effectiveness of the Norwegian Open Fracture Management System in saving lower limbs in rural settings. Materials and Methods: A retrospective and prospective interventional study was carried out in the period 2011 through 2017 in six rural hospitals in Cambodia. The fractures were managed with locally produced external fixators and orthosis developed in 2007. Based on skills and living locations, two local surgeons and one paramedic without reconstructive surgery experience were selected to reach the top of the reconstructive ladder and perform limb salvage surgeries. This study evaluated 56 fractures using the Ganga Hospital Open Injury Score (GHOIS) for Gustilo-Anderson Type IIIA and Type IIIB open fracture classification groups. Results: The primary success rate in open tibia fractures was 64.3% (95% CI, 50.3 - 76.3). The average treatment time to complete healing for all of the patients was 39.6 weeks (95% CI, 34.8 - 44.4). A percentage of 23.2% (95% CI, 13.4 - 36.7) experienced a deep infection. Fifteen of the patients had to undergo soft tissue reconstruction and 22 flaps were performed. Due to non-union, a total of 15 bone grafts were performed. All of the 56 patients in the study gained limb salvage and went back to work. Conclusion: The given fracture management program proves that low-resource countries are able to produce essential surgical tools at high quality and low price. Treatment with external fixation and functional bracing, combined with high-level training of local surgeons, demonstrates that a skilled surgical team can perform advanced limb salvage surgery in low-resource settings.

Iatrogenic Tracheal Rupture Related to Prehospital Emergency Intubation in Adults: A 15-Year Single Center Experience

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.

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.

Terrorist Attacks in Western Europe: A Counter-Terrorism Medicine Analysis

Background: The modern concept of terrorism has its roots in the “old continent” of Western Europe, more specifically in France, during the “Reign of Terror” period of the French Revolution. At the time, this form of state terror had a positive connotation: it was a legitimate means of defending the young state. While no single accepted definition of terrorism exists today, it is universally considered an attack on both state and society. The health care impacts of terrorist attacks often extend disproportionally beyond the casualty toll, but the potential for such events to induce mass casualties remains a concern to Disaster Medicine and Counter-Terrorism Medicine (CTM) specialists. Method: 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 Western Europe from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of the 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: A total of 15,306 events were recorded in Western Europe out of a total of 201,183 events world-wide between the years 1970 and 2019 inclusive. This resulted in a total of 5,548 deaths and 17,187 injuries. Explosives were used as a primary weapon/attack modality in 8,103 attacks, followed by incendiary attacks in 3,050 events and firearm use in 2,955 events. The use of chemical, biological, radiation, and nuclear (CBRN) weapons was rare and only accounted for 47 events. Conclusion: From 1970 through 2019, 9.11% of all terrorist attacks occurred in Western Europe. Compared to global trends of attack methodologies in the same study period, the use of explosives as a primary attack modality in Western Europe was similar (52.94% in Western Europe versus 48.78% Global). Firearm use was comparatively low (19.31% versus 26.77%) and the use of CBRN as an attack modality was rare (0.30% versus 0.20%). The United Kingdom, Spain, and France accounted for over 65% of all terrorist attacks and over 75% of terrorism-related deaths in Western Europe.

Why Bystanders Did Not Perform Cardiopulmonary Resuscitation on Out-of-Hospital Cardiac Arrest Patients: A Multi-Center Study in Hanoi (Vietnam)

Aim: The aim of this study was to determine why bystanders did not use formal Emergency Medical Services (EMS) or conduct cardiopulmonary resuscitation (CPR) on the scene for out-of-hospital cardiac arrest (OHCA) patients in Hanoi, Vietnam. Methods: This was a prospective, observational study of OHCA patients admitted to five tertiary hospitals in the Hanoi area from June 2018 through January 2019. The data were collected through interviews (using a structured questionnaire) with bystanders. Results: Of the 101 patients, 79% were aged <65 years, 71% were men, 79% were witnessed to collapse, 36% were transported to the hospital by formal EMS, and 16% received bystander CPR at the scene. The most frequently indicated reason for not using EMS by the attendants was “using a private vehicle or taxi is faster” (85%). The reasons bystanders did not conduct CPR at the scene included “not recognizing the ailment as cardiac arrest” (60%), “not knowing how to perform CPR” (33%), and “being afraid of doing harm to patients” (7%). Only seven percent of the bystanders had been trained in CPR. Conclusion: The information revealed in this study provides useful information to indicate what to do to increase EMS use and CPR provision. Spreading awareness and training among community members regarding EMS roles, recognition of cardiac arrest, CPR skills, and dispatcher training to assist bystanders are crucial to improve the outcomes of OHCA patients in Vietnam.

Point-of-Care Ultrasound Use by EMS Providers in Out-of-Hospital Cardiac Arrest

Aim: Paramedics received training in point-of-care ultrasound (POCUS) to assess for cardiac contractility during management of medical out-of-hospital cardiac arrest (OHCA). The primary outcome was the percentage of adequate POCUS video acquisition and accurate video interpretation during OHCA resuscitations. Secondary outcomes included POCUS impact on patient management and resuscitation protocol adherence. Methods: A prospective, observational cohort study of paramedics was performed following a four-hour training session, which included a didactic lecture and hands-on POCUS instruction. The Prehospital Echocardiogram in Cardiac Arrest (PECA) protocol was developed and integrated into the resuscitation algorithm for medical non-shockable OHCA. The ultrasound (US) images were reviewed by a single POCUS expert investigator to determine the adequacy of the POCUS video acquisition and accuracy of the video interpretation. Change in patient management and resuscitation protocol adherence data, including end-tidal carbon dioxide (EtCO2) monitoring following advanced airway placement, adrenaline administration, and compression pauses under ten seconds, were queried from the prehospital electronic health record (EHR). Results: Captured images were deemed adequate in 42/49 (85.7%) scans and paramedic interpretation of sonography was accurate in 43/49 (87.7%) scans. The POCUS results altered patient management in 14/49 (28.6%) cases. Paramedics adhered to EtCO2 monitoring in 36/36 (100.0%) patients with an advanced airway, adrenaline administration for 38/38 (100.0%) patients, and compression pauses under ten seconds for 36/38 (94.7%) patients. Conclusion: Paramedics were able to accurately obtain and interpret cardiac POCUS videos during medical OHCA while adhering to a resuscitation protocol. These findings suggest that POCUS can be effectively integrated into paramedic protocols for medical OHCA.

Availability and Characteristics of Humanitarian Health Education and Training Programs: A Web-Based Review

Introduction: Education and training programs are critical to achieve personnel capacity building and professionalization in the rapidly growing humanitarian health sector. Thus, this study aimed to describe the status of humanitarian health education and training programs world-wide. Methods: A web-based analysis was conducted to identify the available humanitarian health programs. The following characteristics of the training programs were described: geographical location, target audience, prerequisite, qualification, curriculum, content, length, modality of delivery, teaching and assessment methods, and tuition fee. Results: The search identified a total number of 142 training programs, most of them available in few countries of the global North. Only seven percent of the identified programs qualified for a master’s degree in humanitarian health. Public health was the most identified content (47.2%). Approximately one-half of the training programs (50.7%) were delivered face-to-face. Theoretical knowledge was the most common method used for teaching and assessment. The duration of the training and tuition fees were different for different programs and qualifications, while target audience, prerequisite, and curriculum design were often vaguely described or missing. Conclusions: The study shows a global inequality in access to humanitarian health training programs due to financial and geographical constraints. The study also reveals gaps in program contents, as well as teaching and assessment methods, all issues that could be addressed by developing cost-effective e-learning and online simulation programs. Lastly, the data from this study provide a learning tool that can be used by humanitarian health educators and training centers to further define and standardize the requirements and competencies of humanitarian health professionals.

Impact of Specific Emergency Measures on Survival in Out-of-Hospital Traumatic Cardiac Arrest

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.

METASTART: A Systematic Review and Meta-Analysis of the Diagnostic Accuracy of the Simple Triage and Rapid Treatment (START) Algorithm for Disaster Triage

Introduction: The goal of disaster triage at both the prehospital and in-hospital level is to maximize resources and optimize patient outcomes. Of the disaster-specific triage methods developed to guide health care providers, the Simple Triage and Rapid Treatment (START) algorithm has become the most popular system world-wide. Despite its appeal and global application, the accuracy and effectiveness of the START protocol is not well-known. Objectives: The purpose of this meta-analysis was two-fold: (1) to estimate overall accuracy, under-triage, and over-triage of the START method when used by providers across a variety of backgrounds; and (2) to obtain specific accuracy for each of the four START categories: red, yellow, green, and black. Methods: A systematic review and meta-analysis was conducted that searched Medline (OVID), Embase (OVID), Global Health (OVID), CINAHL (EBSCO), Compendex (Engineering Village), SCOPUS, ProQuest Dissertations and Theses Global, Cochrane Library, and PROSPERO. The results were expanded by hand searching of journals, reference lists, and the grey literature. The search was executed in March 2020. The review considered the participants, interventions, context, and outcome (PICO) framework and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Accuracy outcomes are presented as means with 95% confidence intervals (CI) as calculated using the binomial method. Pooled meta-analyses of accuracy outcomes using fixed and random effects models were calculated and the heterogeneity was assessed using the Q statistic. Results: Thirty-two studies were included in the review, most of which utilized a non-randomized study design (84%). Proportion of victims correctly triaged using START ranged from 0.27 to 0.99 with an overall triage accuracy of 0.73 (95% CI, 0.67 to 0.78). Proportion of over-triage was 0.14 (95% CI, 0.11 to 0.17) while the proportion of under-triage was 0.10 (95% CI, 0.072 to 0.14). There was significant heterogeneity of the studies for all outcomes (P < .0001). Conclusion: This meta-analysis suggests that START is not accurate enough to serve as a reliable disaster triage tool. Although the accuracy of START may be similar to other models of disaster triage, development of a more accurate triage method should be urgently pursued.

Emergency Preparedness and Disaster Response: There’s an App for That 2.0

Introduction: In disaster response, smartphone applications (or apps) are being used by the layperson, emergency first responders, and health care providers to aid in everything from incident reporting to clinical decision making. However, quality apps are often diluted by the overwhelming number of apps that exist for both the lay public and first responders in the Apple iTunes (Apple Inc.; Cupertino, California USA) and Google Play (Google LLC; Mountain View, California USA) stores. Hypothesis/Problem: A systematic review of disaster response apps was originally completed in 2015; a follow-up review was completed here to evaluate trends and explore novel apps. Methods: A search of the Apple iTunes and Google Play stores was performed using the following terms obtained from PubMed (National Center for Biotechnology Information; Bethesda, Maryland USA) Medical Subject Headings Database: Emergency Preparedness; Emergency Responders; Disaster; Disaster Planning; Disaster Medicine; Bioterrorism; Chemical Terrorism; Hazardous Materials; and the Federal Emergency Management Agency (FEMA [Washington, DC USA]). After excluding any unrelated apps, a working list of apps was formed and categorized based on topics. Apps were categorized by intended user (first responders or the public) and sub-categorized by topic for discussion. Sub-categories included News/Information, Reference/Education, Weather/Natural Disasters, Travel/Navigation, and Communication/Reunification. Results: A search of the Apple iTunes store revealed 394 unique apps and was narrowed to 342 based on relevance to the field and availability on the iPhone. A search of the Google Play store yielded 645 unique applications and was narrowed to 634 based on relevance. Of note, 49 apps appeared in both app stores using the search terms. An aggregate 927 apps from the Apple iTunes and Google Play stores were then critically reviewed by the authors. Apps were sub-categorized based on intended audience, layperson or first responder, and sorted into one of five disaster response categories. Two apps were chosen for discussion from each of the five sub-categories. The highest quality apps were determined from each group based on relevance to emergency preparedness and disaster response, rating, and number of reviews. Conclusion: After comparisons with the 2015 article, many new apps have been developed and previously described apps have been updated, highlighting that this is a constantly changing field deserving of continued analysis and research.
