Floods are the most frequent natural disasters with a significant share of their mortality. Preparedness is capable of decreasing the mortality of floods by at least 50%. This paper aims to present the psychometric properties of a scale developed to evaluate the behavior of preparedness to floods in Sudan and similar settings.

In this methodological scale development study, experts assessed the content validity of the items of the developed scale. Data were collected from key persons of 413 households living in neighborhoods affected by the 2018 floods in Kassala City in Sudan. A pre-tested questionnaire of sociodemographic data and the Flood Preparedness Behavior Scale (FPBS) were distributed to the participants’ houses and recollected. Construct validity of the scale was checked using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency of the scale was checked using Cronbach’s alpha. Test-retest reliability was assessed by Pearson’s correlation coefficient. Item analyses and tests of significance of the difference in the mean scores of the highest and lowest score groups were carried out to ensure discriminatory power of the scale items.

Experts agreed on the scale items. Construct validity of the scale was achieved using EFA by removing 34 items and retaining 25 items that were structured in three factors, named as: measures to be done before, during, and after a flood. Confirmatory factor analysis confirmed the construct obtained by EFA. The loadings of the items on their factors in both EFA and CFA were all > 0.3 with significant associations and acceptable fit indices obtained from CFA. The three factors were found to be reliable in terms of internal consistency (Cronbach’s alpha coefficients for all factors were > 0.7) and test-retest reliability coefficient. In item analysis, the corrected total item correlations for all the items were > 0.3, and significant differences in the means of the highest and lowest score groups indicated good item discrimination power.

The developed 25 items scale is an instrument which produces valid and reliable measures of preparedness behavior for floods in Sudan and similar settings.

In Turkey, a total of 269 earthquakes took place from 1900 through 2023. The most devastating earthquakes in terms of casualties and extensive destruction occurred at 4:17am and 1:24pm local time on February 6, 2023 with the epicenters located in Pazarcik (Kahramanmaras) and Ekinozu (Kahramanmaras) and magnitudes of 7.7Mw and 7.6Mw, respectively. The aim of this study was to define the frequency of lung complications that occurred directly and/or developed during the intensive care follow-up of individuals affected by the Kahramanmaras earthquakes.

A retrospective evaluation was conducted on the files of 69 patients who were rescued from the debris of collapsed buildings after the Kahramanmaras earthquakes and followed up in the intensive care unit in terms of the time under the debris, demographic data, vital signs, and lung complications that were present at the time of admission and developed during follow-up. SPSS for Windows v. 20.0 was used for data analysis.

The study included a total of 69 patients, of whom 29 (42%) were female and 40 (58%) were male. The mean age was 39.9 (SD = 16.9) years. The mean time under the debris was 53.9 (SD = 52) hours, and the mean time from rescue to the intensive care unit admission was 18.7 (SD = 12.8) hours. One or more pulmonary complications were detected in 52.2% (n = 36) of the patients at the time of admission. During the follow-up, 30.4% (n = 21) of the patients developed pulmonary congestion, 13.0% (n = 9) pneumonia, 1.5% (n = 1) alveolar hemorrhage, and 1.5% (n = 1) atelectasis, while no additional lung complications developed in the remaining 37 patients (53.6%).

Severe cases of individuals recovered from the debris can have a high prevalence of earthquake-related lung disorders and chest trauma, which may be associated with high mortality. The timely identification and effective intervention of pulmonary complications that may develop during follow-up can reduce mortality.

Patients with ventricular assist devices (VADs) represent a growing population presenting to Emergency Medical Services (EMS), but little is known about their prehospital care. This study aimed to characterize current EMS protocols in the United States for patients with VADs.

States with state-wide EMS protocols were included. Protocols were obtained from the state EMS website. If not available, the office of the state medical director was contacted. For each state, protocols were analyzed for patient and VAD assessment and treatment variables.

Of 32 states with state-wide EMS protocols, 21 had VAD-specific protocols. With 17 (81%) states noting a pulse may not be palpable, protocols recommended assessing alternate measures of perfusion and mean arterial pressure (MAP; 15 [71%]). Assessment of VAD was advised through listening for pump hum (20 [95%]) and alarms (20 [95%]) and checking the power supply (15 [71%]). For treatment, EMS prehospital consultation was required to begin chest compression in three (14%) states, and mechanical (device) chest compressions were not permitted in two (10%) states. Contact information for VAD coordinator was listed in a minority of five (24%) states. Transport of VAD equipment/backup bag was advised in 18 (86%) states.

This national analysis of EMS protocols found VAD-specific EMS protocols are not universally adopted in the United States and are variable when implemented, highlighting a need for VAD teams to partner with EMS agencies to inform standardized protocols that optimize these patients’ care.

Medical professionals can use mass-casualty triage systems to assist them in prioritizing patients from mass-casualty incidents (MCIs). Correct triaging of victims will increase their chances of survival. Determining the triage system that has the best performance has proven to be a difficult question to answer. The Advanced Prehospital Triage Model (Modelo Extrahospitalario de Triaje Avanzado; META) and Sort, Assess, Lifesaving Interventions, Treatment/Transport (SALT) algorithms are the most recent triage techniques to be published. The present study aimed to evaluate the META and SALT algorithms’ performance and statistical agreement with various standards. The secondary objective was to determine whether these two MCI triage systems predicted patient outcomes, such as mortality, length-of-stay, and intensive care unit (ICU) admission.

This retrospective study used patient data from the trauma registry of an American College of Surgeons Level 1 trauma center, from January 1, 2018 through December 31, 2020. The sensitivity, specificity, and statistical agreement of the META and SALT triage systems to various standards (Revised Trauma Score [RTS]/Sort Triage, Injury Severity Score [ISS], and Lerner criteria) when applied using trauma patients. Statistical analysis was used to assess the relationship between each triage category and the secondary outcomes.

A total of 3,097 cases were included in the study. Using Sort triage as the standard, SALT and META showed much higher sensitivity and specificity in the Immediate category than for Delayed (Immediate sensitivity META 91.5%, SALT 94.9%; specificity 60.8%, 72.7% versus Delayed sensitivity 28.9%, 1.3%; specificity 42.4%, 28.9%). With the Lerner criteria, in the Immediate category, META had higher sensitivity (77.1%, SALT 68.6%) but lower specificity (61.1%) than SALT (71.8%). For the Delayed category, SALT showed higher sensitivity (META 61.4%, SALT 72.2%), but lower specificity (META 75.1%, SALT 67.2%). Both systems showed a positive, though modest, correlation with ISS. For SALT and META, triaged Immediate patients tended to have higher mortality and longer ICU and hospital lengths-of-stay.

Both META and SALT triage appear to be more accurate with Immediate category patients, as opposed to Delayed category patients. With both systems, patients triaged as Immediate have higher mortality and longer lengths-of-stay when compared to Delayed patients. Further research can help refine MCI triage systems and improve accuracy.

Identifying patients at imminent risk of death is critical in the management of trauma patients. This study measures the vital sign thresholds associated with death among trauma patients.

This study included data from patients ≥15 years of age in the American College of Surgeons Trauma Quality Improvement Program (TQIP) database. Patients with vital signs of zero were excluded. Documented prehospital and emergency department (ED) vital signs included systolic pressure, heart rate, respiratory rate, and calculated shock index (SI). The area under the receiver operator curves (AUROC) was used to assess the accuracy of these variables for predicting 24-hour survival. Optimal thresholds to predict mortality were identified using Youden’s Index, 90% specificity, and 90% sensitivity. Additional analyses examined patients 70+ years of age.

There were 1,439,221 subjects in the 2019-2020 datasets that met inclusion for this analysis with <0.1% (10,270) who died within 24 hours. The optimal threshold for prehospital systolic pressure was 110, pulse rate was 110, SI was 0.9, and respiratory rate was 15. The optimal threshold for the ED systolic was 112, pulse rate was 107, SI was 0.9, and respiratory rate was 21. Among the elderly sub-analysis, the optimal threshold for prehospital systolic was 116, pulse rate was 100, SI was 0.8, and respiratory rate was 21. The optimal threshold for ED systolic was 121, pulse rate was 95, SI was 0.8, and respiratory rate was 21.

Systolic blood pressure (SBP) and SI offered the best predictor of mortality among trauma patients. The SBP values predictive of mortality were significantly higher than the traditional 90mmHg threshold. This dataset highlights the need for better methods to guide resuscitation as initial vital signs have limited accuracy in predicting subsequent mortality.

In the United States, all 50 states and the District of Columbia have Good Samaritan Laws (GSLs). Designed to encourage bystanders to aid at the scene of an emergency, GSLs generally limit the risk of civil tort liability if the care is rendered in good faith. Nation-wide, a leading cause of preventable death is uncontrolled external hemorrhage. Public bleeding control initiatives aim to train the public to recognize life-threatening external bleeding, perform life-sustaining interventions (including direct pressure, tourniquet application, and wound packing), and to promote access to bleeding control equipment to ensure a rapid response from bystanders.

This study sought to identify the GSLs in each state and the District of Columbia to identify what type of responder is covered by the law (eg, all laypersons, only trained individuals, or only licensed health care providers) and if bleeding control is explicitly included or excluded in their Good Samaritan coverage.

Good Samaritan Laws providing civil liability qualified immunity were identified in all 50 states and the District of Columbia. One state, Oklahoma, specifically includes bleeding control in its GSLs. Six states – Connecticut, Illinois, Kansas, Kentucky, Michigan, and Missouri – have laws that define those covered under Good Samaritan immunity, generally limiting protection to individuals trained in a standard first aid or resuscitation course or health care clinicians. No state explicitly excludes bleeding control from their GSLs, and one state expressly includes it.

Nation-wide across the United States, most states have broad bystander coverage within GSLs for emergency medical conditions of all types, including bleeding emergencies, and no state explicitly excludes bleeding control interventions. Some states restrict coverage to those health care personnel or bystanders who have completed a specific training program. Opportunity exists for additional research into those states whose GSLs may not be inclusive of bleeding control interventions.

Mass gatherings (MGs) usually represent significant challenges for the public health and safety sector of the host cities. Organizing a safe and successful mass event highly depends on the effective collaboration among different public and private organizations. It is necessary to establish successful coordination to ensure that all the key stakeholders understand their respective roles and responsibilities. The inconsistency between the variety of participating agencies because of their different culture can result in delays in decision making. Interorganizational knowledge transfer can improve the success of the event; however, knowledge transfer among professionals and agencies in MGs is not well-documented.

This study used the 2018 Athens Marathon as the empirical setting to examine how interorganizational knowledge transfer was perceived among the multiple public health and safety professionals during the planning stage of the event.

Data comprised 18 semi-structured, in-depth interviews with key informants, direct observations of meetings, and documentary analysis. Open coding and thematic analysis were used to analyze the data.

Findings indicated that sharing the acquired knowledge was a necessary and challenging step to create an enabling collaborative environment among interacting organizations. Experiential learning was identified as a significant factor, which helped promote joint understanding and partnership work. Informal interpersonal exchanges and formal knowledge transfer activities facilitated knowledge sharing across organizational boundaries, helping to break down silos.

Interorganizational knowledge transfer is a necessary step to achieve joint understanding and create an environment where interaction among agencies can be more effective. The study findings can be beneficial for organizers of marathons and other mass sporting events to support valuable interorganizational collaboration and conduct a safe event.

Music festivals have become an increasingly popular form of mass-gathering event, drawing an increasing number of attendees across the world each year. While festivals exist to provide guests with an enjoyable experience, there have been instances of serious illness, injury, and in some cases death. Large crowds, prolonged exposure to loud music, and high rates of drug and alcohol consumption can pose a dangerous environment for guests as well as those looking after them.

A retrospective review of electronic patient records (EPRs) at the 2022 Glastonbury Festival was undertaken. All patients who attended medical services on-site during the festival and immediately after were included. Patient demographics, diagnosis, treatment received, and discharge destination were obtained and analyzed.

A total of 2,828 patients received on-site medical care. The patient presentation rate (PPR) was 13.47 and the transport-to-hospital rate (TTHR) was 0.30 per 1,000 guests. The most common diagnoses were joint injuries, gastrointestinal conditions, and blisters. Only 164 patients (5.48%) were diagnosed as being intoxicated. Overall, 552 patients (19.52%) were prescribed a medication to take away and 268 (9.48%) had a dressing for a minor wound. One patient (0.04%) underwent a general anesthetic and no patients required cardiopulmonary resuscitation. Most patients were discharged back to the festival site (2,563; 90.66%).

Minor conditions were responsible for many presentations and most patients only required mild or non-invasive interventions, after which they could be safely discharged back to the festival. Older adults were diagnosed with a different frequency of conditions compared to the overall study population, something not reported previously. Intoxicated patients only accounted for a very small amount of the medical workload.

Lactate is a frequently used biomarker in emergency departments (EDs), especially in critically ill patients. The aim of this study is to investigate the relationship between lactate and lactate clearance with in-hospital mortality in unselected ED patients.

This study was carried out retrospectively in the ED of a tertiary hospital. Patients aged 18 years and older whose blood lactate level was obtained in the ED were included in the study. Patients whose lactate value did not have sufficient analytical accuracy, whose lactate value was recorded in the system 180 minutes after admission, who were admitted to the ED as cardiac arrest, and whose ED or hospital outcome was unknown were excluded from the study. According to the first measured lactate value, the patients were divided into three groups: < 2.0mmol/L, 2.0-3.9mmol/L, and ≥ 4.0mmol/L. Lactate clearance was calculated and recorded in patients with one-to-four hours between two lactate values.

During the five-year study period, a total of 1,070,406 patients were admitted to the ED, of which 114,438 (10.7%) received blood gas analysis. The median age of 81,449 patients included in the study was 58 years (IQR: 30, min: 18–max: 117) and 54.4% were female. The study found that non-trauma patients with a lactate level between 2.0-3.9mmol/L had a 2.5-times higher mortality risk, while those with a lactate level of ≥ 4.0mmol/L had a 20.8-times higher risk, compared to those with a lactate level < 2.0mmol/L. For trauma patients, the mortality risk was three-times higher for those with lactate levels between 2.0-3.9mmol/L and nine-times higher for those with a lactate level of ≥ 4.0mmol/L, compared to those with a lactate level < 2.0mmol/L. Among patients with a first measured lactate value ≥ 4.0mmol/L and a two-hour lactate clearance < 20%, the mortality rate was 19.7%. In addition, lactate, lactate clearance, and age were independent variables for mortality in this patient group.

The lactate value in unselected patients in the ED is a biomarker that can be used to predict the prognosis of the patients. In addition, lactate, lactate clearance, and age are independent predictors of mortality.

Prehospital pediatric intubation is a potentially life-saving procedure in which paramedics are relied upon. However, due to the anatomical nature of pediatrics and associated adverse events, it is more challenging compared to adult intubation. In this study, the knowledge and attitude of paramedics was assessed by measuring their overall success rate and associated complications.

An online search using PubMed, Scopus, Web of Science, and Cochrane CENTRAL was conducted using relevant keywords to include studies that assess success rates and associated complications. Studies for eligibility were screened. Data were extracted from eligible studies and pooled as risk ratio (RR) with a 95% confidence interval (CI).

Thirty-eight studies involving 14,207 pediatrics undergoing intubation by paramedics were included in this study. The prevalence of success rate was 82.5% (95% CI, 0.745-0.832) for overall trials and 77.2% (95% CI, 0.713-0.832) success rate after the first attempt. By subgrouping the patients according to using muscle relaxants during intubation, the group that used muscle relaxants showed a high overall successful rate of 92.5% (95% CI, 0.877-0.973) and 79.9% (95% CI, 0.715-0.994) success rate after the first attempt, more than the group without muscle relaxant which represent 78.9% (95% CI, 0.745-0.832) overall success rate and 73.3% (95% CI, 0.616-0.950) success rate after first attempt.

Paramedics have a good overall successful rate of pediatric intubation with a lower complication rate, especially when using muscle relaxants.

Mass gatherings are events where many people come together at a specific location for a specific purpose, such as concerts, sports events, or religious gatherings, within a certain period of time. In mass-gathering studies, many rates and ratios are used to assess the demand for medical resources. Understanding such metrics is crucial for effective planning and intervention efforts. Therefore, this systematic review aims to investigate the usage of rates and ratios reported in mass-gathering studies.

In this systematic review, the PRISMA guidelines were followed. Articles published through December 2023 were searched on Web of Science, Scopus, Cochrane, and PubMed using the specified keywords. Subsequently, articles were screened based on titles, abstracts, and full texts to determine their eligibility for inclusion in the study. Finally, the articles that were related to the study’s aim were evaluated.

Out of 745 articles screened, 55 were deemed relevant for inclusion in the study. These included 45 original research articles, three special reports, three case presentations, two brief reports, one short paper, and one field report. A total of 15 metrics were identified, which were subsequently classified into three categories: assessment of population density, assessment of in-event health services, and assessment of out-of-event health services.

The findings of this study revealed notable inconsistencies in the reporting of rates and ratios in mass-gathering studies. To address these inconsistencies and to standardize the information reported in mass-gathering studies, a Metrics and Essential Ratios for Gathering Events (MERGE) table was proposed. Future research should promote consistency in terminology and adopt standardized methods for presenting rates and ratios. This would not only enhance comparability but would also contribute to a more nuanced understanding of the dynamics associated with mass gatherings.

This case series aims to provide a comprehensive description of the utilization of doppler ultrasonography (USG) and computerized tomography angiography (CTA) in evaluating patients with earthquake-induced crush injuries in the emergency department (ED).

This retrospective case series was conducted on 11 patients who presented with crush injuries following a seismic event. These patients underwent initial assessment using doppler USG, with CTA performed when deemed necessary. Clinical outcomes and diagnostic findings were systematically reviewed.

A cohort of 11 earthquake-related crush injury patients (six females, five males; age 3-59 years), predominantly with lower extremity injuries, with entrapped durations that ranged from 12 to 128 hours. Transport centers received patients from both affected regions and nearby provinces. Initial X-rays identified fractures in two cases. Doppler USG and subsequent CTA were employed for vascular evaluation, with CTA confirming doppler USG findings. Of the 11 patients, five exhibited abnormal doppler USG findings. Four patients required dialysis and four underwent amputation surgery. Fasciotomy and debridement procedures were performed in five and seven patients, respectively. Three patients received hyperbaric oxygen therapy (HBOT).

Doppler USG emerged as a dependable tool for assessing vascular injuries in earthquake-related crush injuries, offering an effective alternative to CTA without the associated contrast agent risks. These findings underscore the need for further research to establish definitive imaging guidelines in these challenging clinical scenarios.

Opioid use disorder is a cause of significant morbidity and mortality. In order to reverse opioid overdose as quickly as possible, many institutions and municipalities have encouraged people with no professional medical training to carry and administer naloxone. This study sought to provide preliminary data for research into the rates of adverse effects of naloxone when administered by bystanders compared to Emergency Medical Services (EMS) personnel, since this question has not been studied previously.

This was a retrospective cohort study performed at an urban, tertiary, academic medical center that operates its own EMS service. A consecutive sample of patients presenting to EMS with opioid overdose requiring naloxone was separated into two groups based on whether naloxone was administered by bystanders or by EMS personnel. Each group was analyzed to determine the incidence of four pre-specified adverse events.

There was no significant difference in the rate of adverse events between the bystander (19%) and EMS (16%) groups (OR = 1.23; 95% CI, 0.63 - 2.32; P = .499) in this small sample. Based on these initial results, a study would need a sample size of 6,188 in order to reach this conclusion with 80% power. Similarly, there were no significant differences in the rates of any of the individual adverse events. Secondary analysis of patients’ demographics showed differences between the two groups which generate hypotheses for further investigation of disparities in naloxone administration.

This preliminary study provides foundational data for further investigation of naloxone administration by bystanders. Adverse events after the prehospital administration of naloxone are rare, and future studies will require large sample sizes. These preliminary data did not demonstrate a statistically significant difference in adverse event rates when comparing naloxone administration by bystanders and EMS clinicians. This study provides data that will be useful for conducting further research on multiple facets of this topic.

Disaster medicine (DM) is a unique field that has undergone significant development as disaster events become increasingly complicated to respond to. However, DM is not recognized by the American Board of Medical Specialties (ABMS) or Accreditation Committee of Graduate Medical Education (ACGME), and therefore lacks board certification. Furthermore, prior studies have shown that there is unique body of DM knowledge not being addressed in emergency medicine (EM) residency or Emergency Medical Services (EMS) fellowship, resulting in fundamental DM topics not being covered amongst graduate medical education (GME) programs most prepared to produce DM physicians. A recently published DM core curriculum addresses this knowledge gap and seeks to promote standardization of DM training.

The objective of this study is to analyze EM residency and EMS fellowship curricula for the inclusion of DM major curriculum topics and subtopics, using the most recently published DM core curriculum as a control.

Both EM residency and EMS fellowship curricula were analyzed for inclusion of DM curriculum topics and subtopics, using the DM curriculum recommendations published by Wexler, et al as a control. A major curriculum topic was deemed covered if at least one related subtopic was described in the curricula. The included and excluded DM topics and subtopics were analyzed using descriptive statistics.

While all the DM major curriculum topics were covered by either EM residency or EMS fellowship, EMS fellowship covered more major curriculum topics (14/15; 93%) than EM residency (12/15; 80%) and EMS fellowship covered more DM curriculum subtopics (58/153; 38%) than EM residency (24/153; 16%). Combined, EM residency and EMS fellowship covered 65 out of 153 (42%) of the DM curriculum subtopics.

Although this study finds that all the DM major curriculum topics will be covered in EM residency followed by EMS fellowship, over one-half of the subtopics are not covered by either program (16% and 38%, respectively) or both programs combined (42%). Increasingly relevant subtopics, such as climate change, droughts, and flooding, are amongst those not covered by either curriculum. Even amongst the DM topics included in GME curricula, an emphasis on themes such as mass treatment, preparedness, and mitigation is likely under-represented. Accreditation from ACGME for DM fellowship would further promote uniform implementation of the updated core curriculum and ensure optimal training of disaster-ready physicians.

Indonesia is located within the Asia-Pacific Ring of Fire, so natural disasters such as earthquakes, tsunamis, volcanic eruptions, floods, and landslides are common. Preparedness is essential to prevent many casualties due to various disasters.

The Aceh, Indonesia earthquake and tsunami in 2004 was one of the most devastating disasters since the 1990s. Some of the victims were children. This is because there was no pattern of preparedness in dealing with disasters when the incident took place; even the word tsunami was not familiar in Indonesia at that time. Thus, the preparation of a disaster preparedness and safety curriculum began to be implemented in Indonesia after the Aceh earthquake and tsunami.

The disaster preparedness and safety curriculum in early childhood education is developed in accordance with the potential and characteristics of the school area. Basic disaster material provided concepts, characteristics and threats, maps, ways of overcoming, and disaster preparedness and security. Facilities and infrastructure supporting disaster preparedness learning used disaster puzzles, disaster posters, songs about disasters, and prayers asking God for help to be protected from disasters.

Volcanic eruption is one of the most common disasters in Indonesia. One of the most fatal volcanic eruptions in Indonesia in 2023 was the eruption of Mount Marapi in West Sumatra. This caused a psychological impact on the survivors and families of the victims who died.

Psychological interventions are usually only provided to survivors. It is very rare to find psychosocial assistance provided to the families of victims who died, even though they also experience acute and prolonged mental health disorders, such as trauma and even depression. So, we offer the idea of remembrance therapy and reading the Qur’an to restore the mental health of the families of the deceased victims.

Dhikr and Qur’an recitation therapy fosters sincerity, patience, and self-acceptance so as to restore mental health in the families of the victims of the Mount Marapi eruption. The therapy serves as a calming factor for the soul because it contains various wisdoms for the calamities experienced. The whole series of therapy is closed with prayer as a form of surrendering the soul to God.
