BACKGROUND: The mass gathering event (MGE) industry is growing globally, including in countries such as Canada. MGEs have been associated with a greater prevalence of injury and illness when compared with daily life events, despite most participants having few comorbidities. As such, adequate health, safety, and emergency medical planning is required. However, there is no single entity regulating these concerns for MGEs, resulting in the responsibility for health planning lying with event organizers. This study aims to compare the legislative requirements for MGE medical response systems in the 13 provinces and territories of Canada.
METHODS: This study is a cross-sectional descriptive analysis of Canadian legislation. Lists of publicly available legislative requirements were obtained by means of the emergency medical services directors and Health Ministries. Descriptive statistics were performed to compare legislation.
RESULTS: Of the 13 provinces and territories, 10 responded. For the missing 3, a law library review confirmed the absence of specific legislation. Most (n = 6; 60%) provinces and territories referred to provisions in their Public Health laws. Four confirmed that MGE medical response was a municipal or local concern to be addressed by the event organizers.
CONCLUSIONS: No provinces could list specific legislation guiding safety, health, and medical response for an MGE.

Introduction Trauma and injuries are common among pilgrims during Hajj, the biggest mass gathering event. Trauma and injury causes vary from falling and pressing in crowds to being burned by boiled water and road traffic accidents (RTA). Time to reach the hospital during highly condensed areas in Hajj are challenges for the public health authorities and the healthcare system to achieve optimum control, management, and outcome. This study aims to explore the pattern of trauma and injuries during Hajj as it is crucial to improve future preventive measures and care quality. Methods A cross-sectional questionnaire-based study was conducted in one hospital in each of the Mena and Arafat (Al-Mashaar\'s areas) in Makkah City, Saudi Arabia, from July 8 to 10, 2022. Data was collected through interviews with patients who visit the hospitals or enter the emergency department and are diagnosed with trauma or injury during the Hajj season of 1443 Hijri date (2022). Results A total of 264 people volunteered to participate in the survey. The mean age by years was 43.5 ± 10.7, and the majority (56%) were between 41 and 64. There were multiple nationalities - the most common nationality was Egyptian (25%), followed by Saudi (10%). The commonest type of trauma was cutting wounds (50%), and the commonest cause was falling (39%), followed by foot twisting (31%). There were 142 cases in Arafat and 122 cases in Mena in the study duration. Tissue contusions are higher in Arafat. Fractures (5%) were in both areas but higher in Mena with burns and sprains. Friction blister injuries were only in Mena and were statistically associated with walking barefoot (p<0.01), which was associated with Egyptians (p<0.05). Also, thigh chafing is only in Mena, while eye traumas and abrasion are only in Arafat. There were four causes of injury that are statistically significantly associated with the area (p<0.05): foot twisting in Arafat, pressing in overcrowding, stoning, and burning in Mena. Moreover, all the RTA cases (n=4) were in Arafat, and all the stoning and burning by boiling water were in Mena. Admission was only for burning (n=2) and falling (n=2) cases and only in Mena emergency hospital; otherwise, all trauma cases were discharged after receiving management - no deaths among the study sample. Injuries in Mena are likely to happen in the evening and night (n=91), while in Arafat, it is more likely in two periods (n=113), in the early morning and afternoon. This difference is statistically significant between the two areas (p<0.05). Most pilgrims (n=129/253) reach the hospital in 16 to 30 minutes. A statistically significant association exists between the duration and the area (p<0.05). Most patients in Arafat (88%) reach the hospital in less than 30 minutes, while only 50% take the same duration in Mena. Conclusion The Hajj season of 1443 H (2022) has a similar trauma pattern and improved outcomes compared to previous seasons. Discovering and digging into the causes of traumas and injuries should be optimized in future research for better control and customized prevention measures. Establishing new and remodeling current prevention measures is recommended for more control.

OBJECTIVE: This study aimed to provide an overview of the scope and challenges of historic events and help better prepare emergency healthcare services for future similar mass gathering events.
METHODS: This was a retrospective descriptive analysis of protest and conflict events in North America from 2021 to 2022.
BACKGROUND: Recent protests, riots, and other conflict events in North America have highlighted the increasing challenges hospital-based and prehospital healthcare providers face. This study provides a retrospective descriptive analysis of protest and conflict events in North America from 2021 to 2022, which may aid emergency healthcare services in understanding the scope and challenges of historic events and help better prepare for future similar mass gathering events.
METHODS: Data collection was performed using a retrospective database search through the Armed Conflict Location & Event Data Project (ACLED) database. The ACLED database was searched using the internal database search functions for recorded events that occurred in North America from January 1, 2021 to December 31, 2022. Date, event type, event subtype, the country of incident, and fatality numbers were extracted. The results were exported into an Excel spreadsheet and analyzed independently by L.C., H.S., and R.H.
RESULTS: There were a total of 52,529 recorded events of political conflict in North America, with 30,269 events in 2021 and 29,260 in 2022. Political conflict events included protests (40,934, 68.8%), violence against civilians (11,532, 19.4%), strategic developments (2,819, 4.7%), battles (2,293, 3.9%), riots (1,909, 3.2%), and remote violence (42, 0.1%). Violence against civilians caused the highest fatalities (13,466, 82.6%), followed by battles (2,662, 16.3%), riots (111, 0.7%), strategic developments, remote violence, and protests (57, 6, and 3 respectively).
CONCLUSIONS: Mexico and the United States accounted for most of the political conflicts in North America across 2021 and 2022. In Mexico, protests and violence against civilians were the most common types of conflict, with the latter accounting for the comparatively high fatality compared with the other countries. Battles in Mexico between cartels were the most deadly political conflicts recorded in North America.

UNASSIGNED: Rates of out-of-hospital cardiac arrest (OHCA) at major sporting events are as high as 0.7 per 100,000 attendees. However, factors contributing to OHCA at mass gatherings have not been well-described. We describe our experience with ten years of medical oversight and OHCA care at a professional football stadium.
UNASSIGNED: We performed a retrospective review of OHCA events between August 2010 and January 2020 at a 65,878-seat football stadium, with a single transporting EMS agency and a single receiving hospital. We analyzed EMS incident reports and matched patients to hospital records for outcome data.
UNASSIGNED: A total of 7,767,345 people attended 115 football games during the study period. There were 21 OHCAs (0.27 per 100,000 attendees). Ninety-five percent of OHCAs were witnessed and 71.4% had an initial shockable rhythm, with bystander AED use in 47.6%. Median EMS response time was 2 minutes (IQR 1-6). For 7 patients defibrillated by EMS, time to defibrillation was 4 minutes (IQR 4-11). Return of spontaneous circulation (ROSC) occurred in 71%, with 47% having good 30-day neurologic survival. All patients with an initial rhythm of asystole died.
UNASSIGNED: The ROSC rate at our stadium exceeded 70% with almost half surviving with good neurologic outcomes, substantially higher than that reported for the general public. We hope that our experience will provide valuable lessons to other similarly sized stadiums.

BACKGROUND: Electronic dance music festivals (EDMF) can cause a significant disruption in the standard operational capacity of emergency medical services (EMS) and hospitals. We determined whether or not the presence of in-event health services (IEHS) can reduce the impact of Europe\'s largest EDMF on the host community EMS and local emergency departments (EDs).
METHODS: We conducted a pre-post analysis of the impact of Europe\'s largest EDMF in July 2019, in Boom, Belgium, on the host community EMS and local EDs. Statistical analysis included descriptive statistics, independent t-tests, and χ2 analysis.
RESULTS: Of 400,000 attendees, 12,451 presented to IEHS. Most patients only required in-event first aid, but 120 patients had a potentially life-threatening condition. One hundred fifty-two patients needed to be transported by IEHS to nearby hospitals, resulting in a transport-to-hospital rate of 0.38/1000 attendees. Eighteen patients remained admitted to the hospital for >24 h; one died after arrival in the ED. IEHS limited the overall impact of the MGE on regular EMS and nearby hospitals. No predictive model proved optimal when proposing the optimal number and level of IEHS members.
CONCLUSIONS: This study shows that IEHS at this event limited ambulance usage and mitigated the event\'s impact on regular emergency medical and health services.

Syndromic surveillance involves the near-real-time collection of data from a potential multitude of sources to detect outbreaks of disease or adverse health events earlier than traditional forms of public health surveillance. The purpose of the present study is to elucidate the role of syndromic surveillance during mass gathering scenarios. In the present review, the use of syndromic surveillance for mass gathering scenarios is described, including characteristics such as methodologies of data collection and analysis, degree of preparation and collaboration, and the degree to which prior surveillance infrastructure is utilized. Nineteen publications were included for data extraction. The most common data source for the included syndromic surveillance systems was emergency departments, with first aid stations and event-based clinics also present. Data were often collected using custom reporting forms. While syndromic surveillance can potentially serve as a method of informing public health policy regarding specific mass gatherings based on the profile of syndromes ascertained, the present review does not indicate that this form of surveillance is a reliable method of detecting potentially critical public health events during mass gathering scenarios.

Using physiological markers to detect patients at risk of deterioration is common. Deaths at music festivals in Australia prompted scrutiny of tools to identify critically unwell patients for transport to hospital. This study evaluated initial physiological parameters to identify patients selected for transport to hospital from a music festival.
A retrospective audit of 2045 presentations at music festivals in Victoria, Australia, was performed. Presentation heart rate, systolic blood pressure, respiratory rate, oxygen saturation, temperature, and Glasgow Coma Scale were assessed using area under the receiver operating characteristic curve (AUROC) analysis, with a prespecified threshold of 0.7.
The only measured variable to exceed the prespecified cutpoint was initial systolic blood pressure, with an AUROC of 0.72 and optimal cutpoint of 122 mmHg. Using commonly accepted cutpoints for variables did not improve detection performance to acceptable levels, nor did using combination systems of cutpoints.
Initial physiological variables are poor predictors of the decision to transport to hospital from music festivals. Systolic blood pressure was significant, but only at a clinically insignificant value. Decisions on which patients to transport from an event site should incorporate more information than initial physiology. Senior clinicians should lead decision-making about hospital transport from music festivals.

A mass gathering medicine training program was established for a 7,200-seat arena. The objectives of this study were to describe the program schema and determine its impact in preparing novice emergency medical technicians (EMTs) to manage the difficulties of large-venue emergency medical services (EMS).
Optional, anonymous surveys were administered to EMTs. Novice EMTs were assessed pre-/post-program implementation, and both novice and experienced EMTs completed self-reported Likert scales. Data were analyzed with nonparametric methods.
A total of 43/56 responses (response rate = 76.8%) were received. Only 37.2% of providers felt prepared to work mass gatherings before the training, and 60.5% stated that their previous education did not prepare them for large-venue challenges. After the training program, novice EMTs were significantly associated with increased knowledge of large-venue EMS procedures (P = 0.0170), higher proficiency using extrication equipment (P = 0.0248), increased patient care skills (P = 0.0438), and both increased confidence working events (P = 0.0002) and better teamwork during patient encounters (P = 0.0001). The majority of EMTs reported the program as beneficial.
Upon hire, EMS providers felt unprepared to work large-venue EMS. The analyses demonstrated that this training program improved select large-venue emergency skills for prehospital providers and may fill a gap in the education system regarding mass gathering medicine.
