Retrospective Analysis of Mosh-Pit-Related Injuries.

OBJECTIVES: Moshing is a violent form of dancing found world-wide at rock concerts, festivals, and electronic dance music events. It involves crowd surfing, shoving, and moving in a circular rotation. Moshing is a source of increased morbidity and mortality. The goal of this study was to report epidemiologic information on patient presentation rate (PPR), transport to hospital rate (TTHR), and injury patterns from patients who participated in mosh-pits. Materials and Methods Subjects were patrons from mosh-pits seeking medical care at a single venue. The events reviewed were two national concert tours which visited this venue during their tour. The eight distinct events studied occurred between 2011 and 2014. Data were collected retrospectively from prehospital patient care reports (PCRs). A single Emergency Medical Service (EMS) provided medical care at this venue. The following information was gathered from each PCR: type of injury, location of injury, treatment received, alcohol or drug use, Advanced Life Support/ALS interventions required, age and gender, disposition, minor or parent issues, as well as type of activity engaged in when injured. RESULTS: Attendance for the eight events ranged from 5,100 to 16,000. Total patient presentations ranged from 50 to 206 per event. Patient presentations per ten thousand (PPTT) ranged from 56 to 130. The TTHR per 10,000 ranged from seven to 20. The mean PPTT was 99 (95% CI, 77-122) and the median was 98. The mean TTHR was 16 (95% CI, 12-29) and the median TTHR was 17. Patients presenting from mosh-pits were more frequently male (57.6%; P<.004). The mean age was 20 (95% CI, 19-20). Treatment received was overwhelmingly at the Basic Life Support (BLS) level (96.8%; P<.000001). General moshing was the most common activity leading to injury. Crowd surfing was the next most significant, accounting for 20% of presentations. The most common body part injured was the head (64% of injuries). CONCLUSIONS: This retrospective review of mosh-pit-associated injury patterns demonstrates a high rate of injuries and presentations for medical aid at the evaluated events. General moshing was the most commonly associated activity and the head was the most common body part injured.

Injury patterns and levels of care at a marathon.

INTRODUCTION: Marathons pose many challenges to event planners. The medical services needed at such events have not received extensive coverage in the literature. OBJECTIVE: The objective of this study was to document injury patterns and medical usage at a category III mass gathering (a marathon), with the goal of helping event planners organize medical resources for large public gatherings. METHODS: Prospectively obtained medical care reports from the five first-aid stations set up along the marathon route were reviewed. Primary and secondary reasons for seeking medical care were categorized. Weather data were obtained, and ambient temperature was recorded. RESULTS: The numbers of finishers were as follows: 4,837 in the marathon (3,099 males, 1,738 females), 814 in the 5K race (362 males, 452 females), and 393 teams in the four-person relay (1,572). Two hundred fifty-one runners sought medical care. The day's temperatures ranged from 39 to 73 degrees F (mean, 56 degrees F). The primary reasons for seeking medical were medication request (26%), musculoskeletal injuries (18%), dehydration (14%), and dermal injuries (11%). Secondary reasons were musculoskeletal injuries (34%), dizziness (19%), dermal injuries (11%), and headaches (9%). Treatment times ranged from 3 to 25.5 minutes and lengthened as the day progressed. Two-thirds of those who sought medical care did so at the end of the race. The majority of runners who sought medical attention had not run a marathon before. CONCLUSIONS: Marathon planners should allocate medical resources in favor of the halfway point and the final first-aid station. Resources and medical staff should be moved from the earlier tents to further augment the later first-aid stations before the majority of racers reach the middle- and later-distance stations.

Variables influencing medical usage rates, injury patterns, and levels of care for mass gatherings.

OBJECTIVES: Mass gatherings create difficult environments for which to plan emergency medical responses. The purpose of this study was to identify those variables that are associated with increased medical usage rates (MURs) and certain injury patterns that can be used to facilitate the planning process. METHODS: Patient information collected at three types of mass gatherings (professional American football and baseball games and rock concerts) over a three-year period was reviewed retrospectively. Specific variables were abstracted: (1) event type; (2) gender; (3) age; (4) weather; and (5) attendance. All 216 events (total attendance 9,708,567) studied were held in the same metropolitan region. All MURs are reported as patients per 10,000 (PPTT). RESULTS: The 5,899 patient encounters yielded a MUR of 6.1 PPTT. Patient encounters totaled 3,659 for baseball games (4.85 PPTT), 1,204 for football games (6.75 PPTT), and 1,036 for rock concerts (30 PPTT). The MUR for Location A concerts (no mosh pits) was 7.49 PPTT, whereas the MUR for the one Location B concert (with mosh pits) was 110 PPTT. The MUR for Location A concerts was higher than for baseball, but not football games (p = 0.005). Gender distribution was equal among patrons seeking medical care. The mean values for patient ages were 29 years at baseball games, 33 years at football games, and 20 years at concerts. The MUR at events held when the apparent temperature was 80 degrees F significantly lower statistically than that at events conducted at temperatures <80 degrees F were (18 degrees C) (4.90 vs. 8.10 PPTT (p = 0.005)). The occurrence of precipitation and increased attendance did not predict an increased MUR. Medical care was sought mostly for minor/basic-level care (84%) and less so for advanced-level care (16%). Medical cases occurred more often at sporting events (69%), and were more common than were cases with traumatic injuries (31%). Concerts with precipitation and rock concerts had a positive association with the incidence of trauma and the incidence of injuries; whereas age and gender were not associated with medical or traumatic diagnoses. CONCLUSIONS: Event type and apparent temperature were the variables that best predicted MUR as well as specific injury patterns and levels of care.

Mass-gathering medical care: a review of the literature.

UNLABELLED: Mass-gatherings events provide a difficult setting for which to plan an appropriate emergency medical response. Many of the variables that affect the level and types of medical needs, have not been fully researched. This review examines these variables. METHODS: An extensive review was conducted using the computerized databases Medline and Healthstar from 1977 through May 2002. Articles selected contained information pertaining to mass-gathering variables. These articles were read, abstracted, analyzed, and compiled. RESULTS: Multiple variables are present during a mass gathering, and they interact in complex and dynamic ways. The interaction of these variables contributes to the number of patients treated at an event (medical usage rate) as well as the observed injury patterns. Important variables include weather, event type, event duration, age, crowd mood and density, attendance, and alcohol and drug use. CONCLUSIONS: Developing an understanding of the variables associated with mass gatherings should be the first step for event planners. After these variables are considered, a thorough needs analysis can be performed and resource allocation can be based on objective data.
