Displaced populations face disproportionately high risk of communicable disease outbreaks given the strains of travel, health care circumstances in their country of origin, and limited access to health care in receiving countries.

Understanding the role of demographic characteristics in outbreaks is important for timely and efficient control measures. Accordingly, this study assesses chickenpox outbreaks in three large refugee camps on mainland Greece from 2016 – 2017, using clinical line-list data from Médecins du Monde (MdM) clinics.

Clinical line-list data from MdM clinics operating in Elliniko, Malakasa, and Raidestos camps in mainland Greece were used to characterize chickenpox outbreaks in these camps. Logistic regression was used to compare the odds of chickenpox by sex, camp, and yearly increase in age. Incidences were calculated for age categories and for sex for each camp outbreak.

Across camps, the median age was 19 years (IQR: 7.00 - 30.00 years) for all individuals and five years (IQR: 2.00 - 8.00 years) for cases. Males were 55.94% of the total population and 51.32% of all cases. There were four outbreaks of chickenpox across Elliniko (n = 1), Malakasa (n = 2), and Raidestos (n = 1) camps. The odds of chickenpox when controlling for age and sex was lower for Malakasa (OR = 0.46; 95% CI, 0.38 - 0.78) and Raidestos (OR = 0.36; 95% CI, 0.24 - 0.56) when compared Elliniko. Odds of chickenpox were comparable between Malakasa and Raidestos (OR = 1.49; 95% CI, 0.92 - 2.42). Across all camps, the highest incidence was among children zero-to-five years of age. The sex-specific incidence chickenpox was higher for males than females in Elliniko and Malakasa, while the incidence was higher among females in Raidestos.

As expected, individuals five years of age and under made up the majority of chickenpox cases. However, 12% of cases were teenagers or older, highlighting the need to consider atypical age groups in vaccination strategies and control measures. To support both host and displaced populations, it is important to consider risk-reduction needs for both groups. Including host communities in vaccination campaigns and activities can help reduce the population burden of disease for both communities.

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.

Earthquakes rank among the most deadly natural disasters, and children are particularly affected due to their inherent vulnerability. Following an earthquake, there is a substantial increase in visits to emergency services. These visits stem not only from patients seeking care for physical traumas resulting from the earthquake and its subsequent complications, but also from individuals affected by the circumstances created by the disaster.

This study aims to determine the characteristics and outcomes of children who presented to the pediatric emergency department (PED) after the earthquake and to evaluate children who had crush injuries at a referral tertiary university hospital away from the earthquake area.

The medical records of children who presented to the PED from the earthquake area from February 6 through March 7, 2023 were retrospectively reviewed. Children rescued from under rubble were categorized as Group 1, those affected by earthquake conditions as Group 2, and patients seeking medical attention due to the follow-up of chronic illnesses were considered as Group 3. Patient data, including sociodemographic characteristics, time period under rubble (TPR), laboratory findings, and details of medical and surgical procedures, developing acute kidney injury (AKI), and the requirement for hemodialysis were recorded.

A total of 252 children were enrolled in the study, with 52 (20.6%) in Group 1, 180 (71.4%) in Group 2, and 16 (6.0%) in Group 3. The median age was six (IQR = 1.7-12.1) years. In the first group (n = 52), 46 (85.2%) children experienced crush injuries, 25 children (46.3%) developed crush syndrome, and 14 of them (14/25; 56.0%) required dialysis. In the second group, the most common diagnoses were upper respiratory tract infections (n = 69; 37.9%), acute gastroenteritis (n = 23; 12.6%), simple physical trauma (n = 16; 8.8%), and lower respiratory tract infections (n = 13; 7.1%). For children in the third group, pediatric neurology (n = 5; 33.3%), pediatric oncology (n = 4; 25.0%), and pediatric nephrology (n = 3; 18.8%) were the most frequently referred specialties.

Crush injuries, crush syndrome, and AKI were the most common problems in the early days following the earthquake. Along with these patients, children who were affected by the environmental conditions caused by the earthquake, as well as children with chronic illnesses, also accounted for a significant portion of visits to the PED, even if they were distant from the disaster area.

The consumption of alcohol within the Australian community continues to rise, impacting care delivery in already over-burdened emergency departments (EDs).

This study aimed to examine the impact of alcohol-related presentations (ARPs) to EDs on days with a public holiday or sporting event.

A retrospective cohort study was undertaken using routinely collected health data pertaining to patient presentations diagnosed with an alcohol-related disorder (ICD-10-AM code F10) to two EDs in Queensland, Australia from January 1, 2016 – December 31, 2020. Descriptive and inferential statistics were used to describe and compare ARPs on event days versus non-event days and uncomplicated versus other ARPs on event days only.

Of all 5,792 ARPs, nine percent (n = 529) occurred on public holidays or sporting event days. When compared by day type, type of presentation, mode of arrival, and day of week differed between event and non-event days. On event days, uncomplicated ARPs differed to other ARPs, with uncomplicated ARPs being younger, having shorter median length-of-stay (LOS), and less likely to be admitted to hospital.

In this multi-site study, public holidays and sporting events had a noteworthy impact on ARPs to EDs. Focused refinement on the clinical management of uncomplicated ARPs is warranted to inform future resource allocation, including on event days.

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.

Investigating the developments in the ever-growing field of disaster medicine and revealing the scientific trends will make an important contribution to researchers in related fields. This study aims to identify the contributions of emergency medicine physicians (EMPs) and trends in disaster medicine publications.

The expressions “disaster medicine” or “disaster*” and “medicine*” were searched in the Web of Science (WoS) database. Research and review papers produced by EMPs from 2001 through 2021 were included in the study. Basic descriptive information was assessed such as the number of publications, authors, citations, most active authors, institutions, countries, and journals. In addition, conceptual, intellectual, and social structures were analyzed.

The study included a total of 346 papers written by 1,500 authors. The mean citation rate per publication was 13.2. Prehospital and Disaster Medicine, Disaster Medicine and Public Health Preparedness, and Academic Emergency Medicine were the journals with the highest number of publications and the highest number of citations. The most common keywords used by the authors were “disaster medicine,” “emergency medicine,” and “disaster/disasters.” According to the distribution of the corresponding authors by country, the United States (n = 175), Japan (n = 23), Italy (n = 20), Australia (n = 17), and Canada (n = 17) had the highest number of publications. The institutions that produced the most publications were John Hopkins University (n = 37), Brigham and Women’s Hospital (n = 27), George Washington University (n = 25), University Piemonte Orientale (n = 24), and Brown University (n = 22).

Increasingly, EMPs have contributed to disaster medicine publications over the years. This study can be used as a guide for EMPs and other researchers who want to contribute to the disaster medicine literature.

Hemodynamic collapse in multi-trauma patients with severe traumatic brain injury (TBI) poses both a diagnostic and therapeutic challenge for prehospital clinicians. Brain injury associated shock (BIAS), likely resulting from catecholamine storm, can cause both ventricular dysfunction and vasoplegia but may present clinically in a manner similar to hemorrhagic shock. Despite different treatment strategies, few studies exist describing this phenomenon in the early post-injury phase. This retrospective observational study aimed to describe the frequency of shock in isolated TBI in prehospital trauma patients and to compare their clinical characteristics to those patients with hemorrhagic shock and TBI without shock.

All prehospital trauma patients intubated by prehospital medical teams from New South Wales Ambulance Aeromedical Operations (NSWA-AO) with an initial Glasgow Coma Scale (GCS) of 12 or less were investigated. Shock was defined as a pre-intubation systolic blood pressure under 90mmHg and the administration of blood products or vasopressors. Injuries were classified from in-hospital computed tomography (CT) reports. From this, three study groups were derived: BIAS, hemorrhagic shock, and isolated TBI without shock. Descriptive statistics were then produced for clinical and treatment variables.

Of 1,292 intubated patients, 423 had an initial GCS of 12 or less, 24 patients (5.7% of the original cohort) had shock with an isolated TBI, and 39 patients had hemorrhagic shock. The hemodynamic parameters were similar amongst these groups, including values of tachycardia, hypotension, and elevated shock index. Prehospital clinical interventions including blood transfusion and total fluids administered were also similar, suggesting they were indistinguishable to prehospital clinicians.

Hemodynamic compromise in the setting of isolated severe TBI is a rare clinical entity. Current prehospital physiological data available to clinicians do not allow for easy delineation between these patients from those with hemorrhagic shock.

After the 2023 Turkey earthquake, thousands of people evacuated to different fields. Earthquake victims still need health care in the evacuation location. This study aims to determine the emergency department (ED) and outpatient clinic utilization characteristics of the evacuated earthquake victims outside the earthquake zone and to provide suggestions for planning the health care facilities in the regions where the evacuated earthquake victims will be placed.

This retrospective, observational study was conducted in a tertiary university hospital from February 7, 2023 through February 20, 2023. All evacuated earthquake victims who presented to the study hospital were included in the study. Non-victim patients were included as the control group. Missing medical records were excluded. Demographic characteristics of the patients, outpatient clinics, International Statistical Classification of Diseases and Related Health Problems-10th Revision (ICD-10) codes, and outcomes were recorded.

A total of 15,128 patients were included in the final analysis. Six-hundred-nine (4.0%) of the patients were evacuated victims. Three-hundred forty-six (56.8%) evacuated victims used the ED. One-hundred fifty-six (25.6%) earthquake victims were in the pediatric age group. Earthquake victims used the ED more than the control group in adult and pediatric age groups (22.5% versus 51.7% and 30.2% versus 71.8%; P <.001, respectively). Earthquake victims frequently presented to the hospital during night shifts in both age groups (P <.05). Pediatric victims were more hospitalized than the control group (4.8% versus 10.9%; P = .001). Diseases of the respiratory system were the most common emergency diagnosis of the victims in both age groups (26.5% and 57.1%, respectively). The most frequently used outpatient clinic was ophthalmology in both age groups (14.6% and 20.5%, respectively).

Evacuated victims, especially pediatric victims, used the ED more than other outpatient clinics. Diseases of the respiratory system were the most common emergency diagnosis of the victims, and the most frequently preferred outpatient clinic was ophthalmology. The most common diseases and frequently preferred clinics should be considered in planning health care for the evacuated earthquake victims.

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.

Medical resuscitations in rugged prehospital settings require emergency personnel to perform high-risk procedures in low-resource conditions. Just-in-Time Guidance (JITG) utilizing augmented reality (AR) guidance may be a solution. There is little literature on the utility of AR-mediated JITG tools for facilitating the performance of emergent field care.

The objective of this study was to investigate the feasibility and efficacy of a novel AR-mediated JITG tool for emergency field procedures.

Emergency medical technician-basic (EMT-B) and paramedic cohorts were randomized to either video training (control) or JITG-AR guidance (intervention) groups for performing bag-valve-mask (BVM) ventilation, intraosseous (IO) line placement, and needle-decompression (Needle-d) in a medium-fidelity simulation environment. For the interventional condition, subjects used an AR technology platform to perform the tasks. The primary outcome was participant task performance; the secondary outcomes were participant-reported acceptability. Participant task score, task time, and acceptability ratings were reported descriptively and compared between the control and intervention groups using chi-square analysis for binary variables and unpaired t-testing for continuous variables.

Sixty participants were enrolled (mean age 34.8 years; 72% male). In the EMT-B cohort, there was no difference in average task performance score between the control and JITG groups for the BVM and IO tasks; however, the control group had higher performance scores for the Needle-d task (mean score difference 22%; P = .01). In the paramedic cohort, there was no difference in performance scores between the control and JITG group for the BVM and Needle-d tasks, but the control group had higher task scores for the IO task (mean score difference 23%; P = .01). For all task and participant types, the control group performed tasks more quickly than in the JITG group. There was no difference in participant usability or usefulness ratings between the JITG or control conditions for any of the tasks, although paramedics reported they were less likely to use the JITG equipment again (mean difference 1.96 rating points; P = .02).

This study demonstrated preliminary evidence that AR-mediated guidance for emergency medical procedures is feasible and acceptable. These observations, coupled with AR’s promise for real-time interaction and on-going technological advancements, suggest the potential for this modality in training and practice that justifies future investigation.

The aim of this study is to determine the demographic, clinical characteristics, and outcomes of the patients who applied to the emergency department (ED) of Akdeniz University Faculty of Medicine Hospital (Antalya, Türkiye) after the Kahramanmaraş-Pazarcık earthquake dated February 6, 2023, as earthquake victims were included in the study. The results of the study could be a guide in terms of emergency health services and the healthy management of disasters.

The study included patients over the age of 18 who presented as earthquake victims to the ED of Akdeniz University Medical Faculty Hospital from February 6, 2023 through March 8, 2023. The demographic data of the patients, including age, gender, earthquake zone, time and manner of arrival to the ED, time under debris, length-of-stay (LOS) in the service and intensive care unit (ICU), infection rates, culture results, and mortality, were retrospectively analyzed using the hospital automation system.

A total of 1,833 earthquake victims presented to the ED. Of these patients, 1,294 were adults and 539 were children. Services and the ICU admitted a total of 137 adult patients. In the first week, 414 (31.99%) of the patients presented to the ED, while 82 (59.85%) of the hospitalized patients were admitted.

Hatay ranked first with 573 (44.28%) patients in the distribution of patients presented to the ED according to earthquake regions. In the distribution of hospitalized patients by earthquake regions, the patients requiring the most hospitalization were from the province of Hatay, with 68 (49.63%) patients.

During hospital observations, the medical staff took 132 culture samples based on the positive clinic of the patient. The microorganisms detected in the culture studies were different from the flora of the hospital. The mortality at seven days was two (1.45%), and at the end of 30 days, the mortality was six (4.37%).

The ED evaluated all affected cases, with most patients being brought by their relatives using their own means, and had low mortality rates despite presenting with fewer injuries. New environmental conditions that developed after the earthquake caused unexpected results, especially in terms of community-acquired agents.

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.

The “Smart Emergency Call Point” is a device designed for requesting assistance and facilitating rapid responses to emergencies. The functionality of smart emergency call points has evolved to include features as real-time photo transmission and communication capabilities for both staff and emergency personnel. These devices are being used to request Emergency Medical Services (EMS) on university campuses. Despite these developments, there has been a lack of previous studies demonstrating significant advantages of integrating smart emergency call points into EMS systems.

The primary goal of this study was to compare the response times of EMS between traditional phone calls and the utilization of smart emergency call points located on university campuses. Additionally, the study aimed to provide insights into the characteristics of smart emergency call points as a secondary objective.

This retrospective database analysis made use of information acquired from Thailand’s EMS at Srinagarind Hospital. The data were gathered over a period of four years, specifically from January 2019 through January 2022. The study included two groups: the first group used the phone number 1669 to request EMS assistance, while the second group utilized the smart emergency call point. The primary focus was on the response times. Additionally, the study documented the characteristics of the smart emergency call points that were used in the study.

Among the 184 EMS operations included in this study, 60.9% (N = 56) involved females in the smart emergency call point group. Notably, the smart emergency call point group showed a higher frequency of operations between the hours of 6:00am and 6:00pm when compared to the 1669 call group (P = .020). In dispatch triage, the majority of emergency call points were categorized as non-urgent, in contrast to the phone group for 1669 which were primarily cases categorized as urgent (P = .010). The average response time for the smart emergency call point group was significantly shorter, at 6.01 minutes, compared to the phone number 1669 group, which had an average response time of 9.14 minutes (P <.001).

In the context of calling for EMS on a university campus, the smart emergency call points demonstrate a significantly faster response time than phone number 1669 in Thailand. Furthermore, the system also offers the capability to request emergency assistance.

There is significant public health interest towards providing medical care at mass-gathering events. Furthermore, mass gatherings have the potential to have a detrimental impact on the availability of already-limited municipal Emergency Medical Services (EMS) resources. This study presents a cross-sectional descriptive analysis to report broad trends regarding patients who were transported from National Collegiate Athletic Association (NCAA) Division 1 collegiate football games at a major public university in order to better inform emergency preparedness and resource planning for mass gatherings.

Patient care reports (PCRs) from ambulance transports originating from varsity collegiate football games at the University of Minnesota across six years were examined. Pertinent information was abstracted from each PCR.

Across the six years of data, there were a total of 73 patient transports originating from NCAA collegiate football games: 45.2% (n = 33) were male, and the median age was 22 years. Alcohol-related chief complaints were involved in 50.7% (n = 37) of transports. In total, 31.5% of patients had an initial Glasgow Coma Scale (GCS) of less than 15. The majority (65.8%; n = 48; 0.11 per 10,000 attendees) were transported by Basic Life Support (BLS) ambulances. The remaining patients (34.2%; n = 25; 0.06 per 10,000 attendees) were transported by Advanced Life Support (ALS) ambulances and were more likely to be older, have abnormal vital signs, and have a lower GCS.

This analysis of ambulance transports from NCAA Division 1 collegiate football games emphasizes the prevalence of alcohol-related chief complaints, but also underscores the likelihood of more life-threatening conditions at mass gatherings. These results and additional research will help inform emergency preparedness at mass-gathering events.

Early detection of ST-segment elevation myocardial infarction (STEMI) on the prehospital electrocardiogram (ECG) improves patient outcomes. Current software algorithms optimize sensitivity but have a high false-positive rate. The authors propose an algorithm to improve the specificity of STEMI diagnosis in the prehospital setting.

A dataset of prehospital ECGs with verified outcomes was used to validate an algorithm to identify true and false-positive software interpretations of STEMI. Four criteria implicated in prior research to differentiate STEMI true positives were applied: heart rate <130, QRS <100, verification of ST-segment elevation, and absence of artifact. The test characteristics were calculated and regression analysis was used to examine the association between the number of criteria included and test characteristics.

There were 44,611 cases available. Of these, 1,193 were identified as STEMI by the software interpretation. Applying all four criteria had the highest positive likelihood ratio of 353 (95% CI, 201-595) and specificity of 99.96% (95% CI, 99.93-99.98), but the lowest sensitivity (14%; 95% CI, 11-17) and worst negative likelihood ratio (0.86; 95% CI, 0.84-0.89). There was a strong correlation between increased positive likelihood ratio (r2 = 0.90) and specificity (r2 = 0.85) with increasing number of criteria.

Prehospital ECGs with a high probability of true STEMI can be accurately identified using these four criteria: heart rate <130, QRS <100, verification of ST-segment elevation, and absence of artifact. Applying these criteria to prehospital ECGs with software interpretations of STEMI could decrease false-positive field activations, while also reducing the need to rely on transmission for physician over-read. This can have significant clinical and quality implications for Emergency Medical Services (EMS) systems.

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.
