Hospital in the Field: Prehospital Management of GHB Intoxication by Medical Assistance Teams

Craic, Ceoil agus COVID-19: the impact of 'Fleadh Cheoil na hÉireann' on presentations to the local emergency department

AIMS

Fleadh Cheoil Na hÉireann, the world's largest Irish music festival, was held in Mullingar in August 2023, gathering a crowd of nearly 600,000 people. Our aim was to assess the impact on presentations to the local emergency department (ED).

METHODS

We performed a retrospective case analysis on all presentations to the ED at Regional Hospital Mullingar (RHM) from 23/7/2023 to 02/09/2023. We also collected data on COVID-19 swab results processed in our laboratory.

RESULTS

There was a 10% increase in ED attendances during the 2 weeks of the Fleadh. There was a statistically significant increase in COVID-19 presentations when compared to national positivity rates.

DISCUSSION/CONCLUSION

Our study shows that the Fleadh led to an increase in all-cause ED visits as well as an increase in COVID-19 cases. Our study plays an important role in informing health service preparation for future host towns of the Fleadh.

Outcomes and Practices of Endotracheal Intubation Using the Glasgow Coma Scale in Acute Non-Traumatic Poisoning: A Systematic Review and Meta-Analysis of Proportions

BACKGROUND

Acute poisoning often results in decreased consciousness, necessitating airway assessment and management. Existing literature in the trauma setting suggests the importance of airway protection in unconscious patients to prevent complications, including aspiration. Practices for endotracheal intubation in non-traumatic acute poisoning are poorly described and variable, particularly regarding the use of a Glasgow Coma Scale (GCS) ≤ 8 threshold for intubation.

METHODS

A systematic review and meta-analysis of proportions was conducted to evaluate intubation rates and outcomes in patients presenting for acute non-traumatic poisoning. Studies were excluded if the primary indication for intubation was not airway protection. We analyzed rates of intubation, mortality, and aspiration by subgrouping patients into GCS ≤ 8, GCS 9-15, or mixed GCS. Common and random-effects analysis were used, supplemented by subgroup analyses.

RESULTS

39 studies were included in the analysis, involving 15,959 patients. Random-effects pooled intubation rates varied significantly across GCS categories: GCS ≤ 8 (30.0%, I2 = 92%, p < 0.01), GCS 9-15 (1.0%, I2 = 0%, p = 0.91), and mixed GCS (11.0%, I2 = 94%, p < 0.01), p-value <0.01 for subgroup difference. Aspiration rates also varied: GCS ≤ 8 (19.0%, I2 = 84%, p < 0.01), GCS 9-15 (4.0%, I2 = 78%, p < 0.01), and mixed group (5.0%, I2 = 72%, p < 0.01), p-value <0.01 for subgroup difference. Mortality rates remained low across all groups: GCS ≤ 8 (1.0%, I2 = 0%, p = 0.62), GCS 9-15 (1.0%, I2 = 0%, p = 0.99), and mixed group (2.0%, I2 = 68%, p < 0.01).

CONCLUSION

The conventional "less than 8, intubate" approach may not be directly applicable to acute poisoning patients due to heterogeneity in patient presentation, intubation practices, and low mortality. Therefore, a nuanced approach is warranted to optimize airway management strategies tailored to individual patient needs.

A systematic review of interventions that impact alcohol and other drug-related harms in licensed entertainment settings and outdoor music festivals

BACKGROUND

Harms associated with the use of alcohol and other drugs (AOD) in licensed entertainment settings (LES) and outdoor music festivals (OMF) are ongoing public health and criminal justice concerns. This systematic review provides a comprehensive, synthesized report on the evidence base of interventions that impact harm in these settings, and how they affect health, behavioral, and criminal justice outcomes.

METHODS

Nine databases were searched for experimental and observational studies published between 2010 and 2021. Studies were included if they were peer-reviewed, published in English, described interventions which could impact AOD-related harms in LES or OMF (and were delivered in these environments), and reported on health, criminal justice and/or behavioral outcomes. Methodological quality was assessed using the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies and the Critical Appraisal Skills Program for qualitative studies. A narrative synthesis was conducted to synthesize outcomes across studies. The review protocol was registered in PROSPERO (CRD42020140004).

RESULTS

Of the 48,303 studies screened, 100 met the inclusion criteria. 86 focused solely on reducing alcohol-related harm, 7 on reducing illicit drug-related harm, and 7 on both. Most (n = 88) focused on LES and evaluated changes in laws and regulations (n = 28) and/or multicomponent interventions/policies (n = 41). Multicomponent interventions showed the best results for both health (62% positive) and criminal justice (84% positive) outcomes, with 71% of studies being rated as strong quality. There was also good evidence to support the careful application of trading hour restrictions and limited but promising evidence to support medical services and drug checking.

CONCLUSION

The breadth, quality and volume of evidence regarding what works in reducing AOD-related harm in recreational settings have increased in the past decade, particularly regarding LES. Findings support onsite medical services (reducing ambulance transfer rates), multicomponent interventions targeting alcohol accessibility and availability (reducing assaults), and drug checking services, but suggest other interventions such as drug detection dogs may exacerbate harm. Further, higher quality research is required to address identified gaps in the evidence base, particularly on optimal interventions within OMF, around illicit drugs more broadly and in the Global South.

Unity in diversity: A systematic review on the GHB using population

BACKGROUND

Over the past decades gamma-hydroxybutyrate (GHB) has emerged as a popular drug with high potential of (ab)use due to its euphoric and relaxing effects. An overview of different populations using GHB is urgently needed, since this would enable development of adequate prevention and treatment policies to diminish the risks associated with GHB use. We systematically reviewed literature on different GHB using populations, comparing demographic characteristics, GHB use patterns, psychosocial aspects and psychiatric comorbidity.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using Rayyan software. Original studies published from January 1997 up to October 2019 on GHB use were included. Out of 80 full-text articles, 60 articles of 51 unique studies were included. Most studies included people using GHB 1) presenting at emergency departments (n = 22), 2) recruited from the general population (n = 11), or 3) presenting at addiction care (n = 8).

RESULTS

Three main sub-populations of people using GHB are described in the literature: people using GHB recreationally without adverse effects; people using GHB recreationally with adverse effects, and people with dependence on GHB. These groups show considerable overlap in gender, age range, and comorbid substance use, as well as amount of GHB use per occasion. Differences are related to frequency and function of GHB use, the number of comas experienced, as well as work status, and psychiatric comorbidity.

CONCLUSION

Policy interventions should aim at preventing the transition from recreational substance use to GHB use, as most users are experienced recreational substance users prior to starting GHB use. When people use GHB regularly, interventions should aim at reducing the level of GHB use and preventing GHB use-related harm. Longitudinal studies and population-based probability sampling are required for more insight in the dynamics of GHB use in different sub-populations, and the transition from one group to the other, ultimately leading to dependence on GHB.

Characteristics, presentation and outcomes of music festival patrons with stimulant drug-induced serotonin toxicity

OBJECTIVE

A large number of stimulant drug-associated deaths at music festivals in Australia were reported during the southern hemisphere summer of 2018-2019. This led to the prehospital deployment of healthcare professional-led critical care response teams. We aimed to describe the characteristics, clinical presentation, management and outcomes of music festival patrons with stimulant drug-induced serotonin toxicity managed using this model during the study period.

METHODS

We performed a retrospective observational study of patients presenting with stimulant drug-induced serotonin toxicity and/or drug-induced hyperthermia who presented between December 2017 and December 2019. Comprehensive follow-up data were collected for those patients who required hospital admission. Data included demographics, clinical features, management and disposition, hospital outcomes and laboratory data, stratified by severity of presentation.

RESULTS

Forty-seven patients were included. Median age was 21.9 years (interquartile range 19.6-22.2). 3,4-Methylenedioxymetamphetamine was the most frequently reported agent ingested (32/47). After stratification, 13 of 47 patients were classified as mild, 20 of 47 as moderate and 14 of 47 as severe. Median presenting temperature in this latter cohort was 41.1°C (40.5-42.0°C). All severely ill patients required intensive care unit admission, with a median hospital stay of 4.63 days (interquartile range 2.08-8.36). End-organ complications were reported in 11 of 14 patients. No mortalities were reported. All patients (13/13) from the mild cohort and 15 of 20 patients from the moderate cohort were treated and discharged on-site.

CONCLUSIONS

Severe illness was associated with a high incidence of end-organ impairment. A high proportion of patients without severe disease were able to be successfully managed at the event without transport to hospital. No deaths are reported in this series.

Measuring the Masses: The Current State of Mass-Gathering Medical Case Reporting (Paper 1)

INTRODUCTION

Case reports are commonly used to report the health outcomes of mass gatherings (MGs), and many published reports of MGs demonstrate substantial heterogeneity of included descriptors. As such, it is challenging to perform rigorous comparisons of health services and outcomes between similar and dissimilar events. The degree of variation in published reports has not yet been investigated.

OBJECTIVE

Examine patterns of post-event medical reporting in the existing literature and identify inconsistencies in reporting.

METHODS

A systematic review of case reports was conducted. Included were English studies, published between January 2009 and December 2018, in Prehospital and Disaster Medicine (PDM) or Current Sports Medicine Reports (CSMR). Analysis of each paper was used to develop a list of 27 categories of data.

RESULTS

Seventy-five studies were initially reviewed with 54 publications meeting the inclusion criteria. Forty-two were full case reports (78%) and 12 were conference proceedings (22%). Of the 27 categories of data studied, only 13 were consistently reported in more than 50% of publications. Reporting patterns included inconsistent use of terminology/language and variable retrievability of reports. Reporting on event descriptors, hazard and risk analysis, and clinical outcomes were also inconsistent.

DISCUSSION

Case reports are essential tools for researchers and event team members such as medical directors and event producers. The authors found that current case reports, in addition to being inconsistent in content, were generally descriptive rather than explanatory; that is, focused on describing the outcomes as opposed to exploring possible connections between context and health outcomes.

CONCLUSION

This paper quantifies and demonstrates the current state of heterogeneity in MG event reporting. This heterogeneity is a significant impediment to the functional use of published reports to further the science of MG planning and to improve health outcomes. Future work based on the insights gained from this analysis will aim to align and standardize reporting to improve the quality and value of event reporting.

Measuring the Masses: A Proposed Template for Post-Event Medical Reporting (Paper 4)

BACKGROUND

Standardizing and systematizing the reporting of health outcomes from mass gatherings (MGs) will improve the quality of data being reported. Setting minimum standards for case reporting is an important strategy for improving data quality. This paper is one of a series of papers focused on understanding the current state, and shaping the future state, of post-event case reporting.

METHODS

Multiple data sources were used in creating a lean, yet comprehensive list of essential reporting fields, including a: (1) literature synthesis drawn from analysis of 54 post-event case reports; (2) comparison of existing data models for MGs; (3) qualitative analysis of gaps in current case reports; and (4) set of data domains developed based on the preceding sources.

FINDINGS

Existing literature fails to consistently report variables that may be essential for not only describing the health outcomes of a given event, but also for explaining those outcomes. In the context of current and future state reporting, 25 essential variables were identified. The essential variables were organized according to four domains, including: (i) Event Domain; (ii) Hazard and Risk Domain; (iii) Capacity Domain; and (iv) Clinical Domain.

DISCUSSION

The authors propose a first-generation template for post-event medical reporting. This template standardizes the reporting of 25 essential variables. An accompanying data dictionary provides background and standardization for each of the essential variables. Of note, this template is lean and will develop over time, with input from the international MG community. In the future, additional groups of variables may be helpful as "overlays," depending on the event category and type.

CONCLUSIONS

This paper presents a template for post-event medical reporting. It is hoped that consistent reporting of essential variables will improve both data collection and the ability to make comparisons between events so that the science underpinning MG health can continue to advance.

Measuring the Masses: Domains Driving Data Collection and Analysis for the Health Outcomes of Mass Gatherings (Paper 3)

INTRODUCTION

Without a robust evidence base to support recommendations for medical services at mass gatherings (MGs), levels of care will continue to vary and preventable morbidity and mortality will exist. Accordingly, researchers and clinicians publish case reports and case series to capture and explain some of the health interventions, health outcomes, and host community impacts of MGs. Streamlining and standardizing post-event reporting for MG medical services and associated health outcomes could improve inter-event comparability, thereby supporting and promoting growth of the evidence base for this discipline. The present paper is focused on theory building, proposing a set of domains for data that may support increasingly comprehensive, yet lean, reporting on the health outcomes of MGs. This paper is paired with another presenting a proposal for a post-event reporting template.

METHODS

The conceptual categories of data presented are based on a textual analysis of 54 published post-event medical case reports and a comparison of the features of published data models for MG health outcomes.

FINDINGS

A comparison of existing data models illustrates that none of the models are explicitly informed by a conceptual lens. Based on an analysis of the literature reviewed, four data domains emerged. These included: (i) the Event Domain, (ii) the Hazard and Risk Domain, (iii) the Capacity Domain, and (iv) the Clinical Domain. These domains mapped to 16 sub-domains.

DISCUSSION

Data modelling for the health outcomes related to MGs is currently in its infancy. The proposed illustration is a set of operationally relevant data domains that apply equally to small, medium, and large-sized events. Further development of these domains could move the MG community forward and shift post-event health outcomes reporting in the direction of increasing consistency and comprehensiveness.

CONCLUSION

Currently, data collection and analysis related to understanding health outcomes arising from MGs is not informed by robust conceptual models. This paper is part of a series of nested papers focused on the future state of post-event medical reporting.

Measuring the Masses: Mass-Gathering Medical Case Reporting, Conceptual Modeling - The DREAM Model (Paper 5)

INTRODUCTION

Without a robust evidence base to support recommendations for first aid, health, and medical services at mass gatherings (MGs), levels of care will continue to vary. Streamlining and standardizing post-event reporting for MG medical services could improve inter-event comparability, and prospectively influence event safety and planning through the application of a research template, thereby supporting and promoting growth of the evidence base and the operational safety of this discipline. Understanding the relationships between categories of variables is key. The present paper is focused on theory building, providing an evolving conceptual model, laying the groundwork for exploring the relationships between categories of variables pertaining the health outcomes of MGs.

METHODS

A content analysis of 54 published post-event medical case reports, including a comparison of the features of published data models for MG health outcomes.

FINDINGS

A layered model of essential conceptual components for post-event medical reporting is presented as the Data Reporting, Evaluation, & Analysis for Mass-Gathering Medicine (DREAM) model. This model is relational and embeds data domains, organized operationally, into "inputs," "modifiers," "actuals," and "outputs" and organized temporally into pre-, during, post-event, and reporting phases.

DISCUSSION

Situating the DREAM model in relation to existing models for data collection vis a vis health outcomes, the authors provide a detailed discussion on similarities and points of difference.

CONCLUSION

Currently, data collection and analysis related to understanding health outcomes arising from MGs is not informed by robust conceptual models. This paper is part of a series of nested papers focused on the future state of post-event medical reporting.

The Development of PRIMA - A Belgian Prediction Model for Patient Encounters at Mass Gatherings

Introduction:

Mass gatherings (MGs) grow in frequency around the world. With the intrinsic potential for significant health risks for all involved, MGs pose a challenge for those responsible for the provision of on-site medical care. Belgian law obliges local governments to identify and analyze the risks involving a MG. Though medical risk factors are long known, all too often, resourcing for in-event health services is based on anecdotal and previous experiences.

Problem:

Despite the fast-evolving science on MGs, the lack of reliable tools – based on empirical and analytical approaches – to predict patient presentation rates (PPRs) at MGs remains.

Methods:

A two-step method was followed to develop, update, and support a Plan Risk Manifestation (PRIMA) program. First, a continuous systematic literature review was conducted. Once developed, the model was run using data obtained from Belgian Federal Public Service (FPS; Brussels, Belgium) Health, Food Chain Safety, and Environment (HFCSE); event organizers; and municipalities.

Results:

In total, 231 studies and documents were included to form the program. With the data provided, three variables were computed to run the calculation model to predict the PPR. Three medical risk axes were defined for this model: (1) isolation risk; (2) population risk; and (3) risk at illness. A combined dataset was derived from the prediction of the PRIMA program combined with the actual data obtained after the MG. This proved a solid basis for the calculation model of the PRIMA program.

Conclusion:

Despite that validation is needed, the PRIMA program and its prediction model for PPRs at MGs carries the promise of a general, applicable prediction and risk analysis tool for a multitude of events.

Moshpit Medicine: The Experience of an Australian Event Resuscitation Team

The authors reviewed case reports of patients presenting to an advanced medical assessment and resuscitation service at 15 music events over 22 days from June 2018 through March 2019 around Australia. Event size ranged from 4,000 to 57,500 participants. Events observed had a mean patient presentation rate (PPR) of 0.83% (SD = 0.59%) and mean transport to hospital rate (TTHR) of 1.89 (SD = 0.92) per 10,000. Two-hundred and twenty-one cases were reviewed and tabulated for descriptive analysis.Lower rates of traumatic injuries were seen compared to other case reports, and minor procedures represented a minor but important part of the team's workload. Methylenedioxymethamphetamine (MDMA) use was reported by 33.0% of patients on the day of presentation; almost one-half of these reported a co-ingestion. Patients presenting after using MDMA were more likely to have an elevated temperature. Eight percent of patients presented with temperature above 38°C. Patients with an initial temperature above 38°C were more likely to require hospitalization. On-site electrocardiograph (ECG), blood gas, ultrasound, and urinalysis were found to be useful in decision support. In total, 29.8% of patients required sedation during their encounter; 2.7% required rapid sequence induction at the event. Mean observation time was 44 minutes, with longer observation required in MDMA and hallucinogen-related presentations.

On the Way Out: An Analysis of Patient Transfers from Four Large-Scale North American Music Festivals Over Two Years

Introduction

Music festivals are globally attended events that bring together performers and fans for a defined period of time. These festivals often have on-site medical care to help reduce the impact on local health care systems. Historically, the literature suggests that patient transfers off-site are frequently related to complications of substance use. However, there is a gap in understanding why patients are transferred to hospital when an on-site medical team, capable of providing first aid services blended with a higher level of care (HLC) team, is present.

Objective

The purpose of this study is to better understand patterns of injuries and illnesses that necessitate transfer when physician-led HLC teams are accessible on-site.

Methods

This is a prospective, descriptive case series analyzing patient encounter documentation from four large-scale, North American, multi-day music festivals.

Results/Discussion

On-site medical teams that included HLC team members were present for the duration of each festival, so every team was able to “treat and release” when clinically appropriate. Over the course of the combined 34 event days, there were 10,406 patient encounters resulting in 156 individuals being transferred off-site for assessment, diagnostic testing, and/or treatment. A minority of patients seen were transferred off-site (1.5%). The patient presentation rate (PPR) was 16.5/1,000. The ambulance transfer rate (ATR) was 0.12/1,000 attendees, whereas the total transfer-to-hospital rate (TTHR), when factoring in non-ambulance transport, was 0.25/1,000. In contrast to existing literature on transfers from music festivals, the most common reason for transfer off-site was for musculo-skeletal (MSK) injuries (53.8%) that required imaging.

Conclusion

The presence of on-site HLC teams impacted the case mix of patients transferred to hospital, and may reduce the number of transfers for intoxication. Confounding preconceptions, patients in the present study were transferred largely for injuries that required specialized imaging and testing that could not be performed in an out-of-hospital setting. These results suggest that a better understanding of the specific effects on-site HLC teams have on avoiding off-site transfers will aid in improving planning for music festivals. The findings also identify areas for further improvement in on-site care, such as integrated on-site radiology, which could potentially further reduce the impact of music festivals on local health services. The role of non-emergency transport vehicles (NETVs) deserves further attention.

Impact of Patients Presenting with Alcohol and/or Drug Intoxication on In-Event Health Care Services at Mass-Gathering Events: An Integrative Literature Review

BACKGROUND

There is a growing body of literature relating to mass-gathering events. A common thread amongst this literature, particularly the literature relating to music festivals, is the incidence of patients presenting with substance and/or alcohol intoxication. However, the impact of alcohol and/or drugs on the provision of in-event health care services has not been explored in detail.AimThe goal of this review was to develop an understanding of the impact of alcohol and/or drugs on in-event health care services at mass-gathering events.

METHOD

This paper used integrative review as a methodology. The articles included in this literature review were sourced by searching databases inclusive of Medline (Ovid; US National Library of Medicine, National Institutes of Health; Bethesda, Maryland USA), Scopus (Elsevier; Amsterdam, Netherlands), PsycINFO (Ovid; American Psychological Association; Washington DC, USA), and Pub Med (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA). Identified manuscripts that met the inclusion criteria were thematically analyzed.

RESULTS

In total, 12 manuscripts met the inclusion criteria for this review. A thematic analysis of these manuscripts identified three main themes: (i) predictive factors, (ii) patient presentation rates, and (iii) levels of care.

CONCLUSION

Substance use and/or intoxication can place a strain on in-event medical services at mass-gathering events. Of the various types of mass-gathering events, music festivals appear to be the most affected by substance use and intoxication. BullockM, RanseJ, HuttonA.

Altered Mental Status: Current Evidence-based Recommendations for Prehospital Care

Introduction

In the United States emergency medical services (EMS) protocols vary widely across jurisdictions. We sought to develop evidence-based recommendations for the prehospital evaluation and treatment of a patient with an acute change in mental status and to compare these recommendations against the current protocols used by the 33 EMS agencies in the State of California.

Methods

We performed a literature review of the current evidence in the prehospital treatment of a patient with altered mental status (AMS) and augmented this review with guidelines from various national and international societies to create our evidence-based recommendations. We then compared the AMS protocols of each of the 33 EMS agencies for consistency with these recommendations. The specific protocol components that we analyzed were patient assessment, point-of-care tests, supplemental oxygen, use of standardized scoring, evaluating for causes of AMS, blood glucose evaluation, toxicological treatment, and pediatric evaluation and management.

Results

Protocols across 33 EMS agencies in California varied widely. All protocols call for a blood glucose check, 21 (64%) suggest treating adults at <60mg/dL, and half allow for the use of dextrose 10%. All the protocols recommend naloxone for signs of opioid overdose, but only 13 (39%) give specific parameters. Half the agencies (52%) recommend considering other toxicological causes of AMS, often by using the mnemonic AEIOU TIPS. Eight (24%) recommend a 12-lead electrocardiogram; others simply suggest cardiac monitoring. Fourteen (42%) advise supplemental oxygen as needed; only seven (21%) give specific parameters. In terms of considering various etiologies of AMS, 25 (76%) give instructions to consider trauma, 20 (61%) to consider stroke, and 18 (55%) to consider seizure. Twenty-three (70%) of the agencies have separate pediatric AMS protocols; others include pediatric considerations within the adult protocol.

Conclusion

Protocols for patients with AMS vary widely across the State of California. The evidence-based recommendations that we present for the prehospital diagnosis and treatment of this condition may be useful for EMS medical directors tasked with creating and revising these protocols.

The Event Chain of Survival in the Context of Music Festivals: A Framework for Improving Outcomes at Major Planned Events

Despite the best efforts of event producers and on-site medical teams, there are sometimes serious illnesses, life-threatening injuries, and fatalities related to music festival attendance. Producers, clinicians, and researchers are actively seeking ways to reduce the mortality and morbidity associated with these events. After analyzing the available literature on music festival health and safety, several major themes emerged. Principally, stakeholder groups planning in isolation from one another (ie, in silos) create fragmentation, gaps, and overlap in plans for major planned events (MPEs).

The authors hypothesized that one approach to minimizing this fragmentation may be to create a framework to “connect the dots,” or join together the many silos of professionals responsible for safety, security, health, and emergency planning at MPEs. Adapted from the well-established literature regarding the management of cardiac arrests, both in and out of hospital, the “chain of survival” concept is applied to the disparate groups providing services that support event safety in the context of music festivals. The authors propose this framework for describing, understanding, coordinating and planning around the integration of safety, security, health, and emergency service for events. The adapted Event Chain of Survival contains six interdependent links, including: (1) event producers; (2) police and security; (3) festival health; (4) on-site medical services; (5) ambulance services; and (6) off-site medical services.

The authors argue that adapting and applying this framework in the context of MPEs in general, and music festivals specifically, has the potential to break down the current disconnected approach to event safety, security, health, and emergency planning. It offers a means of shifting the focus from a purely reactive stance to a more proactive, collaborative, and integrated approach. Improving health outcomes for music festival attendees, reducing gaps in planning, promoting consistency, and improving efficiency by reducing duplication of services will ultimately require coordination and collaboration from the beginning of event production to post-event reporting.

Mortality at Music Festivals: Academic and Grey Literature for Case Finding

Objective

Deaths at music festivals are not infrequently reported in the media; however, the true mortality burden is difficult to determine as the deaths are not yet systematically documented in the academic literature.

Methods

This was a literature search for case examples using academic and gray literature sources, employing both retrospective and prospective searches of media sources from 1999-2014.

Results

The gray literature documents a total of 722 deaths, including traumatic (594/722; 82%) and non-traumatic (128/722; 18%) causes. Fatalities were caused by trampling (n=479), motor-vehicle-related (n=39), structural collapses (n=28), acts of terror (n=26), drowning (n=8), assaults (n=6), falls (n=5), hanging (n=2), and thermal injury (n=2). Non-traumatic deaths included overdoses (n=96/722; 13%), environmental causes (n=8/722; 1%), natural causes (n=10/722; 1%), and unknown/not reported (n=14/722; 2%). The majority of non-trauma-related deaths were related to overdose (75%).

The academic literature documents trauma-related deaths (n=368) and overdose-related deaths (n=12). One hundred percent of the trauma-related deaths reported in the academic literature also were reported in the gray literature (n=368). Mortality rates cannot be reported as the total attendance at events is not known.

Conclusions

The methodology presented in this manuscript confirms that deaths occur not uncommonly at music festivals, and it represents a starting point in the documentation and surveillance of mortality.

Observed Benefits to On-site Medical Services during an Annual 5-day Electronic Dance Music Event with Harm Reduction Services

Background

With increasing attendance and media attention, large-scale electronic dance music events (EDMEs) are a subset of mass gatherings that have a unique risk profile for attendees and promoters. Shambhala Music Festival (Canada) is a multi-day event in a rural setting with a recognized history of providing harm reduction (HR) services alongside medical care.

Study/Objective

This manuscript describes the medical response at a multi-day electronic music festival where on-site HR interventions and dedicated medical care are delivered as parallel public health measures.

Methods

This study was a descriptive case report. Medical encounters and event-related data were documented prospectively using an established event registry database.

Results

In 2014, Shambhala Music Festival had 67,120 cumulative attendees over a 7-day period, with a peak daily attendance of 15,380 people. There were 1,393 patient encounters and the patient presentation rate (PPR) was 20.8 per one thousand. The majority of these (90.9%) were for non-urgent complaints. The ambulance transfer rate (ATR) was 0.194 per one thousand and 0.93% of patient encounters were transferred by ambulance. No patients required intubation and there were no fatalities.

Harm reduction services included mobile outreach teams, distribution of educational materials, pill checking facilities, a dedicated women’s space, and a “Sanctuary” area that provided non-medical peer support for overwhelmed guests. More than 10,000 encounters were recorded by mobile and booth-based preventive and educational services, and 2,786 pills were checked on-site with a seven percent discard rate.

Conclusion

Dedicated medical and HR services represent two complementary public health strategies to minimize risk at a multi-day electronic music festival. The specific extent to which HR strategies reduce the need for medical care is not well understood. Incorporation of HR practices when planning on-site medical care has the potential to inform patient management, reduce presentation rates and acuity, and decrease utilization and cost for local, community-based health services.

Mass-gathering Medicine: Risks and Patient Presentations at a 2-Day Electronic Dance Music Event

Introduction

Music festivals, including electronic dance music events (EDMEs), increasingly are common in Canada and internationally. Part of a US $4.5 billion industry annually, the target audience is youth and young adults aged 15-25 years. Little is known about the impact of these events on local emergency departments (EDs).

Methods

Drawing on prospective data over a 2-day EDME, the authors of this study employed mixed methods to describe the case mix and prospectively compared patient presentation rate (PPR) and ambulance transfer rate (ATR) between a first aid (FA) only and a higher level of care (HLC) model.

Results

There were 20,301 ticketed attendees. Seventy patient encounters were recorded over two days. The average age was 19.1 years. Roughly 69% were female (n=48/70). Forty-six percent of those seen in the main medical area were under the age of 19 years (n=32/70). The average length of stay in the main medical area was 70.8 minutes. The overall PPR was 4.09 per 1,000 attendees. The ATR with FA only would have been 1.98; ATR with HLC model was 0.52. The presence of an on-site HLC team had a significant positive effect on avoiding ambulance transfers.

Discussion

Twenty-nine ambulance transfers and ED visits were avoided by the presence of an on-site HLC medical team. Reduction of impact to the public health care system was substantial.

Conclusions

Electronic dance music events have predictable risks and patient presentations, and appropriate on-site health care resources may reduce significantly the impact on the prehospital and emergency health resources in the host community.
