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.
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 attendance9,708,567) 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) was110 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°F significantly lower statistically than that at events conducted at temperatures <80°F were (18°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 atsporting events (69%), and were more common than were cases with traumatic injuries (31%). Concerts with precipitation and rock concerts had a positive association withthe 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.
Introduction:Hospitals the world over have been involved in disasters, both internal and external. These two types of disasters are independent, but not mutually exclusive. Internal disasters are isolated to the hospital and occur more frequently than do external disasters. External disasters affect the community as well as the hospital. This paper first focuses on common problems encountered during acute-onset disasters, with regards to hospital operations and caring for victims. Specific injury patterns commonly seen during natural disasters are reviewed. Second, lessons learned from these common problems and their application to hospital disaster plans are reviewed.Methods:An extensive review of the available literature was conducted using the computerized databases Medline and Healthstar from 1977 through March 1999. Articles were selected if they contained information pertaining to a hospital response to a disaster situation or data on specific disaster injury patterns. Selected articles were read, abstracted, analyzed, and compiled.Results:Hospitals continually have difficulties and failures in several major areas of operation during a disaster. Common problem areas identified include communication and power failures, water shortage and contamination, physical damage, hazardous material exposure, unorganized evacuations, and resource allocation shortages.Conclusions::Lessons learned from past disaster-related operational failures are compiled and reviewed. The importance and types of disaster planning are reviewed.
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°F (mean, 56°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.
