Integrating the six C's of disaster response: Lessons from the mega terrorist attack on October 7, 2023.

On October 7, 2023, over 2,500 Hamas terrorists infiltrated Israel from Gaza and killed over 1,400 people and injured 2,800, resulting in the largest terrorist attack in Israel's history. Several models describe the principles of managing a mass casualty event. One of them is an Australian construct known as the six C's. While command, control, and coordination are familiar concepts, the six C's emphasize the importance of communication and community (consequences and community connection). We describe how two emergency departments in Israel-Assuta Ashdod and the Hadassah Medical Center-Ein Kerem-responded to this disaster in the context of the six C's.

Artificial Intelligence-Based Left Ventricular Ejection Fraction by Medical Students for Mortality and Readmission Prediction.

INTRODUCTION: Point-of-care ultrasound has become a universal practice, employed by physicians across various disciplines, contributing to diagnostic processes and decision-making. AIM: To assess the association of reduced (<50%) left-ventricular ejection fraction (LVEF) based on prospective point-of-care ultrasound operated by medical students using an artificial intelligence (AI) tool and 1-year primary composite outcome, including mortality and readmission for cardiovascular-related causes. METHODS: Eight trained medical students used a hand-held ultrasound device (HUD) equipped with an AI-based tool for automatic evaluation of the LVEF of non-selected patients hospitalized in a cardiology department from March 2019 through March 2020. RESULTS: The study included 82 patients (72 males aged 58.5 ± 16.8 years), of whom 34 (41.5%) were diagnosed with AI-based reduced LVEF. The rates of the composite outcome were higher among patients with reduced systolic function compared to those with preserved LVEF (41.2% vs. 16.7%, p = 0.014). Adjusting for pertinent variables, reduced LVEF independently predicted the composite outcome (HR 2.717, 95% CI 1.083-6.817, p = 0.033). As compared to those with LVEF ≥ 50%, patients with reduced LVEF had a longer length of stay and higher rates of the secondary composite outcome, including in-hospital death, advanced ventilatory support, shock, and acute decompensated heart failure. CONCLUSION: AI-based assessment of reduced systolic function in the hands of medical students, independently predicted 1-year mortality and cardiovascular-related readmission and was associated with unfavorable in-hospital outcomes. AI utilization by novice users may be an important tool for risk stratification for hospitalized patients.

Secondary Ambulance Transfers During the Mass-Casualty Terrorist Attack in Israel on October 7, 2023.

On October 7, 2023, Israel experienced the worst terror attack in its history - 1,200 people were killed, 239 people were taken hostage, and 1,455 people were wounded. This mass-casualty event (MCE) was more specifically a mega terrorist attack. Due to the overwhelming number of victims who arrived at the two closest hospitals, it became necessary to implement secondary transfers to centers in other areas of the country. Historically, secondary transfer has been implemented in MCEs but usually for the transfer of critical patients from a Level 2 or Level 3 Trauma Center to a Level 1 Center. Magen David Adom (MDA), Israel's National Emergency Pre-Hospital Medical Organization, is designated by the Health Ministry as the incident command at any MCE. On October 7, in addition to the primary transport of victims by ambulance to hospitals throughout Israel, they secondarily transported patients from the two closest hospitals - the Soroka Medical Center (SMC; Level 1 Trauma Center) in Beersheba and the Barzilai Medical Center (BMC; Level 2 Trauma Center) in Ashkelon. Secondary transport began five hours after the event started and continued for approximately 12 hours. During this time, the terrorist infiltration was still on-going. Soroka received 650 victims and secondarily transferred 26, including five in Advanced Life Support (ALS) ambulances. Barzilai received 372 and secondarily transferred 38. These coordinated secondary transfers helped relieve the overwhelmed primary hospitals and are an essential component of any MCE strategy.

Characteristics and Motivational Factors of Whole Blood and Convalescent Plasma Donors during the SARS-CoV-2 Pandemic in Israel.

Demands for whole blood (WB) and COVID-19 convalescent plasma (CCP) donations during the SARS-CoV-2 (COVID-19) pandemic presented unprecedented challenges for blood services throughout the world. This study aims to understand the motivating factors that drive WB and CCP donations in the context of the pandemic. This cross-sectional study is based on data extracted from surveys of the two volunteer donor cohorts. The findings reveal that when compared to CCP donors, WB donors were more likely to view donation as a form of social engagement (97.7% vs. 87.1%, p < 0.01), advantageous in the workplace (46.4% vs. 28.6%, p < 0.01), advantageous in their social network (58.6% vs. 47.0%, p = 0.01), and view their donation in the context of positive self-satisfaction (99% vs. 95.1%, p = 0.01). The average age of CCP donors was 7.1 years younger than those who donated WB (p < 0.01). Motivational factors were also analyzed by sex and religiosity. In conclusion, whereas both donor groups showed a high motivation to partake in these life-saving commitments, WB donors were more likely to be motivated by factors that, when better-understood and implemented in policies concerning plasma donations, may help to increase these donations.

POINT-OF-CARE ULTRASOUND BY EMERGENCY PHYSICIANS FOR URETERAL STONE DETECTION: A CASE SERIES AND REVIEW OF THE LITERATURE.

Symptomatic urolithiasis is a common cause of emergency department (ED) visits, with non-contrast computed tomography (NCCT) considered the imaging gold standard. According to current guidelines, POCUS is limited to the evaluation of hydronephrosis as a secondary sign of acute ureteral stones. However, the use of POCUS to detect ureteral stones may lead to decreased radiation to the patient and a more rapid diagnosis. This case series describes 10 patients with suspected symptomatic urolithiasis who were diagnosed accurately by emergency physicians using POCUS to detect obstructive ureteral stones. In three of the cases, POCUS significantly changed the patient's management. This article also describes the proper techniques for the emergency physician to learn to master POCUS for ureteral stone detection.

Empowering Medical Students: Harnessing Artificial Intelligence for Precision Point-of-Care Echocardiography Assessment of Left Ventricular Ejection Fraction.

Introduction: Point-of-care ultrasound (POCUS) use is now universal among nonexperts. Artificial intelligence (AI) is currently employed by nonexperts in various imaging modalities to assist in diagnosis and decision making. Aim: To evaluate the diagnostic accuracy of POCUS, operated by medical students with the assistance of an AI-based tool for assessing the left ventricular ejection fraction (LVEF) of patients admitted to a cardiology department. Methods: Eight students underwent a 6-hour didactic and hands-on training session. Participants used a hand-held ultrasound device (HUD) equipped with an AI-based tool for the automatic evaluation of LVEF. The clips were assessed for LVEF by three methods: visually by the students, by students + the AI-based tool, and by the cardiologists. All LVEF measurements were compared to formal echocardiography completed within 24 hours and were evaluated for LVEF using the Simpson method and eyeballing assessment by expert echocardiographers. Results: The study included 88 patients (aged 58.3 ± 16.3 years). The AI-based tool measurement was unsuccessful in 6 cases. Comparing LVEF reported by students' visual evaluation and students + AI vs. cardiologists revealed a correlation of 0.51 and 0.83, respectively. Comparing these three evaluation methods with the echocardiographers revealed a moderate/substantial agreement for the students + AI and cardiologists but only a fair agreement for the students' visual evaluation. Conclusion: Medical students' utilization of an AI-based tool with a HUD for LVEF assessment achieved a level of accuracy similar to that of cardiologists. Furthermore, the use of AI by the students achieved moderate to substantial inter-rater reliability with expert echocardiographers' evaluation.

Artificial Intelligence-Powered Left Ventricular Ejection Fraction Analysis Using the LVivoEF Tool for COVID-19 Patients.

We sought to prospectively investigate the accuracy of an artificial intelligence (AI)-based tool for left ventricular ejection fraction (LVEF) assessment using a hand-held ultrasound device (HUD) in COVID-19 patients and to examine whether reduced LVEF predicts the composite endpoint of in-hospital death, advanced ventilatory support, shock, myocardial injury, and acute decompensated heart failure. COVID-19 patients were evaluated with a real-time LVEF assessment using an HUD equipped with an AI-based tool vs. assessment by a blinded fellowship-trained echocardiographer. Among 42 patients, those with LVEF < 50% were older with more comorbidities and unfavorable exam characteristics. An excellent correlation was demonstrated between the AI and the echocardiographer LVEF assessment (0.774, p < 0.001). Substantial agreement was demonstrated between the two assessments (kappa = 0.797, p < 0.001). The sensitivity, specificity, PPV, and NPV of the HUD for this threshold were 72.7% 100%, 100%, and 91.2%, respectively. AI-based LVEF < 50% was associated with worse composite endpoints; unadjusted OR = 11.11 (95% CI 2.25-54.94), p = 0.003; adjusted OR = 6.40 (95% CI 1.07-38.09, p = 0.041). An AI-based algorithm incorporated into an HUD can be utilized reliably as a decision support tool for automatic real-time LVEF assessment among COVID-19 patients and may identify patients at risk for unfavorable outcomes. Future larger cohorts should verify the association with outcomes.

Biomedicine and the treatment of difference in a Jerusalem emergency department.

Biomedicine has played a key role in the dissemination of modern social norms, such as the emphasis on individual autonomy and the distinction between science and religion. This study examines the way the mostly-Jewish members of the medical staff at an emergency department of a Jerusalem hospital perceive Jewish ultra-Orthodox and Arab patients' behaviors vis-à-vis the existing biomedical norms. We analyzed participants' perceptions in terms of the social constructs they reveal, their meanings, and their implications. Semi-structured in-depth interviews were conducted with 24 staff members and were analyzed using content analysis. The staff described challenges in treating Arab and ultra-Orthodox patients, which they related to both groups' embeddedness in traditional "cultures" and collective identities. According to the participants, in both cases, the patients' cultural affiliations constrained their sense of individual autonomy and rationality. However, in the comparative analysis, two differences emerged. First, while both groups were perceived to diverge from modern norms of individual autonomy, in the case of Arab patients, these characteristics were presented as disruptive and potentially threatening to the hospital staff. By contrast, in the case of ultra-Orthodox patients, adherence to traditional and collective values was more likely to be represented as a risk to the patient, rather than to the staff. Second, staff were more likely to provide accommodations for ultra-Orthodox patients than for Arab patients. These accommodations were often described in the frame of "cultural competency." We suggest that divergences in how staff understood and responded to perceived cultural differences of each group reflect unequal impacts of structural determinants of health, including of political conflict. We recommend moving beyond the conceptual framework of cultural competency to strengthen the staff's structural competency, cultural and structural humility, and critical consciousness.

The association between sonographic common bile duct dilatation and outcomes in emergency department patients with cholangitis.

BACKGROUND: The presentation of the patient with acute cholangitis (AC) ranges from mild illness to life-threatening shock. Therefore, prompt diagnosis and treatment are critical. Abdominal ultrasound (US) is the imaging of choice to locate bile duct dilatation. Other modalities include abdominal computed tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP). OBJECTIVES: To determine whether sonographic common bile duct dilatation in emergency department (ED) patients with AC predicts outcomes including sepsis, hospital length of stay (LOS), admission to the intensive care unit (ICU), time to ERCP, and mortality. METHODS: Electronic medical records of all patients hospitalized in a tertiary care medical center between July 2012-February 2021 with a discharge diagnosis of cholangitis were assessed. Patients were dichotomously classified as CBD dilated or CBD non-dilated based on ultrasound. Dilation was defined as CBD larger than 6 mm in patients younger than 60 or larger than 6 mm + 1 mm per decade in patients over 60. RESULTS: The study included 271 patients- 172 with CBD dilation versus 99 without. Mean LOS was 9.92 days for those with a dilated CBD versus 13.4 days without. The mean time to ERCP was 4.26 days for those with a dilated CBD versus 6.56 days without. Sepsis, mortality, and ICU admission were scarce and there was no statistically significant difference between the cohorts. CONCLUSION: Patients with a dilated CBD per the abdominal US performed during the patient's ED stay, underwent ERCP earlier, and were hospitalized fewer days than patients without CBD dilation.

Factors that affect pain management in adults diagnosed with acute appendicitis in the emergency department: A retrospective study.

BACKGROUND: Analgesic treatment, including with opioids, can safely be given to patients who are suspected of having appendicitis. The study examined factors which may influence the treatment of pain in appendicitis in the adult emergency department (ED). A secondary objective was to determine if analgesia affected clinical outcomes. METHODS: This single-center retrospective study examined medical records of all adult patients with a discharge diagnosis of appendicitis. Patients were categorized based on the type of analgesia received in the ED. Variables included the day of week and staffing shift of presentation, gender, age, and triage pain scale, as well as time to ED discharge, imaging, operation, and hospital discharge. Univariable and multivariable logistic regression models were performed to determine which factors influenced treatment and affected outcomes. RESULTS: Records of 1839 patients were categorized into three groups - 883 (48%) did not receive analgesia, 571 (31%) received only non-opioid medications, and 385 (21%) received at least one opioid. Patients with a higher triage pain level were significantly more likely to receive analgesia (4-6: OR = 1.85; 95% CI = 1.2-2.84, 7-9: OR = 3.36; 95% CI = 2.18-5.17, 10: OR = 10.78; 95% CI = 6.38-18.23) and at least one opioid (4-6: OR = 2.88; 95% CI = 1.13-7.34, 7-9: OR = 4.36; 95% CI = 1.73-11.01, 10: OR = 6.23; 95% CI = 2.42-16.09). Male gender was associated with a significantly lower likelihood of receiving analgesia (OR = 0.74; 95% CI = 0.61-0.9), but a significantly greater likelihood of receiving at least one opioid given that they received any pain medication (OR = 1.87; 95% CI = 1.41-2.48). Patients aged 25-64 years old were significantly more likely to receive at least one opioid if they received any pain medication (25-44: OR = 1.47; 95% CI = 1.08-2.02, 45-64: OR = 1.78; 95% CI = 1.15-2.76). Presentation to the ED on Sundays was associated with lower rates of opioid treatment (OR = 0.63; 95% CI = 0.42-0.94). Regarding clinical outcomes, patients who received analgesia waited longer for imaging (+0.58 h; 95% CI = 0.31-0.85), stayed longer in the ED (+2.2 h; 95% CI = 1.60-2.79), and had a slightly longer hospitalization (+0.62d; 95% CI = 0.34-0.90). CONCLUSIONS: Almost half of patients with appendicitis didn't receive analgesia, with most of those treated receiving only non-opioid analgesia. Older age and Sunday presentations were associated with less opioid treatment. Patients who received analgesia waited longer for imaging, stayed longer in the ED, and had a longer hospitalization.

Disaster Medicine Education for Israeli Medical Response Teams to the Ukrainian Refugee Crisis.

INTRODUCTION: Disaster Medicine (DM) requires skills, knowledge, and prior experience that are rarely put to test by health care providers. Pediatric DM presents unique challenges in terms of both knowledge and practice. METHODS: An anonymous survey consisting of demographic and five-point Likert scale questions was administered to physicians, nurses, and other medical personnel from Israel's major medical emergency teams who were deployed to respond to the refugee crisis in Ukraine. This included teams from the Hadassah and Tel Aviv Sourasky Medical Centers and the Israel Ministry of Health. RESULTS: Of the 171 members of the medical teams deployed on the Ukraine border, a total of 105 responses were obtained (61.4%) from 61 physicians, 50 nurses, and 12 other health care providers. The teams were composed of pediatricians (31.6%), internal medicine physicians (21.6%), Emergency Medicine and intensive care physicians (18.0%), and 31.0% other specialties.For 60% of the participants, this was their first deployment, and 78% had received no training in DM. Members rated the need for DM training at 4/5 (IQR 3-5). Forty-nine (49) members (46.6%) were not briefed on situational awareness and 97 members (89.5%) were not trained in the recognition of acute stress reactions. The responders also rated their concerns about providing medical aid to children at 2/5 (IQR 1-3). A medical clown was part of the teams 42.8% of the time; the presence of clowns was rated at a median of 4/5 (IQR 4-5). The team members underscored the need for more targeted training in DM at 5/5 (IQR 3-5). CONCLUSION: The findings highlight the need for the formulation of a disaster education model that includes pediatric DM.

Impact of repeated military conflicts on civilian patterns of emergency medical services utilization: A retrospective cohort study.

OBJECTIVE: To assess the impact of repeated rocket attacks on a civilian population during successive military conflicts on the patterns of emergency medical services (EMS) utilization. DESIGN: This retrospective cohort study (2008-2021) analyzed EMS data from one region of Israel characterized by intensive rocket attacks on a civilian population during four successive military conflicts. EMS activity for the periods prior to, during, and after the conflicts was compared. Data included call volume, type of calls ("medical illness," "motor vehicle collision (MVC)," and "other-injuries"), and level of response (advanced life support (ALS) or basic life support (BLS)). RESULTS: Compared to the Pre-Conflict period, there were statistically significant decreased volumes of calls during the 2008 (-20 percent), 2012 (-13 percent), and 2021 (-11 percent) military conflicts for "medical illness" and during the 2008 (-23 percent), 2012 (-30 percent), and 2021 (-31 percent) for "MVC." Decreases in calls for "medical illness" were accompanied by decreased ALS dispatches (-28, -33, and -18 percent for 2008, 2012, and 2021, respectively). The number of calls returned to preconflict values during the Post-Conflict periods. No change was evidenced in numbers of calls during the 2014 military conflict. CONCLUSION: Military conflicts involving a civilian population were usually found to be associated with lower numbers of calls for the categories of "medical illness" and "MVC." Less calls for "medical illness" were associated with fewer ALS dispatches. There was a rapid return of call volumes to preconflict levels shortly after a ceasefire was reached. The absence of change in calls during the 2014 conflict suggests involvement of habituation processes.

Social and structural determinants of emergency department use among Arab and Jewish patients in Jerusalem.

BACKGROUND: A growing body of research demonstrates that economic conditions and racial and ethnic disparities result in excessive overuse of emergency departments (EDs) by a small group of socioeconomically marginalized residents. Knowledge and understanding of these issues on the part of the healthcare team can promote equality by providing structurally competent care. This study aims to identify the major social and structural factors related to patterns of ED visits by Arab and Jewish patients in Israel, where access to health services is covered by universal national health insurance. METHODS: A cross-sectional study was conducted using questionnaires of ED patients in a tertiary care medical center in Jerusalem. The hospital is the largest of the three EDs in Jerusalem with over 90,000 adult patient visits a year. The sample was stratified by ethnicity, including 257 Jewish patients and 170 Arab patients. The outcome variable was repeat visits for the same reason to the ED within 30 days. RESULTS: There were differences between Jewish and Arab patients' social and structural characteristics, including health status, socioeconomic status, feeling of safety, and social support. There were also significant differences in some of the characteristics of health service utilization patterns, including ED repeat visits, language barriers when seeking healthcare in the community, and seeking information about medical rights. The variables associated with repeat visits were different between the two groups: among the Arab patients, repeat visits to the ED were associated with concerns about personal safety, whereas among the Jewish patients, they were associated with poverty. CONCLUSION: The study illustrates the gaps that exist between the Arab and Jewish population in Israel. The findings demonstrated significant differences between populations in both health status and access to health services. In addition, an association was found in each ethnic group between different structural factors and repeat ED requests. This study supports previous theories and findings of the relationship between structural and social factors and patterns of health services utilization.

The Crowd Crush at Mount Meron: Emergency Medical Services Response to a Silent Mass Casualty Incident.

On April 30, 2021, a total of 45 died and 112 were injured in a crowd crush at a religious festival on Mount Meron, Israel. Unlike a bomb blast, building collapse, mass shooting, or stampede, the incident lacked a dramatic, noticeable trigger and may be termed a "silent mass casualty incident (MCI)." This may have resulted in a slight delay in response. Magen David Adom (MDA)-Israel's National Emergency Medical Services Organization-was the main prehospital response to the MCI. MDA's intense planning, organization of medical infrastructure, and on-site MCI drill before the event allowed for the rapid, coordinated treatment and evacuation of casualties by ambulance and helicopter. The use of volunteers facilitated an effective response to the event. A "rolling reinforcement" system of ambulances helped treat and transport those at the scene while placing staff at stations throughout the country to serve routine emergency calls.

The quality, safety, feasibility, and interpretive accuracy of echocardiographic and lung ultrasound assessment of COVID-19 patients using a hand-held ultrasound.

BACKGROUND: The association between COVID-19 infection and the cardiovascular system necessitates the use of an echocardiogram in this setting. Information on the utilization, safety, and quality of point-of-care cardiac and lung ultrasound using a hand-held device in these patients is scarce. AIMS: To investigate the safety, technical aspects, quality indices, and interpretive accuracy of a hand-held echocardiogram in patients with COVID-19. METHODS: From April-28 through July-27, 2020, consecutive patients with COVID-19 underwent hand-held echocardiogram and lung ultrasound evaluation (Vscan Extend™; GE Healthcare) within 48-h of admission. The operators recorded a series of technical parameters and graded individual experiences. The examinations were further analyzed by a blinded fellowship-trained echocardiographer for general quality, proper acquisition, and right ventricular (RV) demonstration. RESULTS: Among 103 patients, 66 (64.1%) were male. Twenty-nine (28.2%) patients could not turn on their left side and 23 (22.3%) could not maintain effective communication. The mean length of each echocardiogram study was 8.5 ± 2.9 min, battery usage was 14 ± 5%, and mean operator-to-patient proximity was 59 ± 11 cm. Ninety-five (92.2%) examinations were graded as fair/good quality. A fair agreement was demonstrated between the operator and the echocardiographer for general ultrasound quality (Kappa = 0.329, p < 0.001). A fair-good correlation (r = 0.679, p < 0.001) and substantial agreement (Kappa = 0.612, p < 0.001) were demonstrated between the operator and echocardiographer for left ventricular ejection fraction (LVEF), whereas a fair agreement was demonstrated for RV systolic function (Kappa = 0.308, p = 0.002). LVEF agreement was also assessed using the Bland-Altman analysis revealing a mean bias of -0.96 (95% limits of agreement 9.43 to -11.35; p = 0.075). CONCLUSIONS: Among patients with COVID-19, echocardiography with a hand-held ultrasound is a safe and reasonable alternative for a complete formal study (<10% poor-quality indices). Echocardiogram assessment by the operators during the exam acquisition is reliable for LVEF, while RV systolic function should be subsequently offline reassessed.

Neutrality, conflict, and structural determinants of health in a Jerusalem emergency department.

BACKGROUND: Medical neutrality is a normative arrangement that differentiates a zone of medical treatment disconnected from the field of politics. While medical neutrality aims to ensure impartial healthcare for all and to shield the healthcare personnel from political demands, it can also divert attention away from conflicts and their effects on health inequity. This article analyzes how healthcare professionals understand and negotiate the depoliticized space of the emergency department (ED) through their views on neutrality. It also examines how medical staff use depoliticized concepts of culture to account for differences in the health status of patients from disadvantaged groups. These questions are examined in the context of the Israeli-Palestinian conflict. METHODS: Twenty-four in-depth, semi-structured interviews were conducted with healthcare personnel in a Jerusalem hospital's ED. All but one of the participants were Jewish. The interviews were analyzed using qualitative content analysis and Grounded Theory. RESULTS: The ED staff endorsed the perspective of medical neutrality as a nondiscriminatory approach to care. At the same time, some medical staff recognized the limits of medical neutrality in the context of the Israeli-Palestinian conflict and negotiated and challenged this concept. While participants identified unique health risks for Arab patients, they usually did not associate these risks with the effects of conflict and instead explained them in depoliticized terms of cultural and behavioral differences. Culture served as a non-controversial way of acknowledging and managing problems that have their roots in politics. CONCLUSIONS: The normative demand for neutrality works to exclude discussion of the conflict from clinical spaces. The normative exclusion of politics is a vital but under-appreciated aspect of how political conflict operates as a structural determinant of health. Healthcare personnel, especially in the ED, should be trained in structural competency. This training may challenge the neglect of issues that need to be solved at the political level and enhance health equity, social justice, and solidarity.

The Role of Israel's Emergency Medical Services During a Pandemic in the Pre-Exposure Period.

OBJECTIVE: The scientific literature on coronavirus disease (COVID-19) is extensive, but little is written about the role of emergency medical services (EMS). The objective of this study is to describe the role of Magen David Adom (MDA), Israel's national emergency prehospital medical organization, in the pre-exposure period, before widespread governmental action. These efforts were based on (1) phone diagnosis, dispatch, and transport; and (2) border management checkpoints. METHODS: This is a descriptive study of MDA's role in pandemic response during the pre-exposure period. Medical emergency telephone calls from either individuals or medical sources were identified by a dispatcher as "suspected COVID-19" based on symptoms and travel exposure. Data were also collected for travelers approaching the MDA border checkpoint at Ben-Gurion International Airport. RESULTS: The total number of protected transports during this time was 121. Of these, 44 (36.3%) were referred by medical sources, and 77 (63.7%) were identified as "suspected COVID-19" by dispatchers. The checkpoint was accessed by 156 travelers: 87 were sent to home-quarantine; 12 were transported to the hospital; 18 were refused entry; and 39 required no further action. CONCLUSION: EMS can work effectively in the pre-exposure period through instructing home quarantine, providing protected transport, and staffing border control checkpoints.
