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.

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).

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.

Event type and apparent temperature were the variables that best predicted MUR as well as specific injury patterns and levels of care.

Mass gatherings may result in an acute increase in the number of people seeking medical care potentially causing undue stress to local emergencymedical services (EMS) and hospitals. Often, temporary medical facilities are established within the mass gathering venue. Emergency Medical Services providers encountering patients in the field should be equipped with effective protocols to determine transport destination (venue facility vs. hospital).

Paramedics are capable of appropriately using triage criteria written specifically for a particular mass gathering. The use of triage criteria, when appliedcorrectly, decreases over-triage to the venue facility and under-triage to the hospital.

Paramedics triaged patients at a mass gathering to a temporary venue facility or to a single emergency department using criteria specific for the event. Cases were reviewed to determine if the patients transported went to an appropriate facility and if the triage criteria were applied appropriately. Results: Transport destination was consistent with that dictated by the criteria for 78% of cases. Analysis of these cases shows that the criteria had a sensitivity of 100% (95% CI = 58–100%) and a specificity of 90% (95% CI = 73–98%) for predicting which patients needed hospital services and which could be cared for safely in the temporary clinic setting.

Triage by paramedics at the point of patient contact may reduce transporting of patients to hospitals unnecessarily. Patients in need of hospital services were identified. Point-of-contact triage should be applied in mass gatherings.

The aim of this study was to use a visual analogue scale (VAS) to measure the adequacy of prehospital pain management. Patients reported pain severity at two points in time during treatment and transport by ambulance paramedics. The change in pain score was compared with a benchmark reduction of 20 mm that has been shown to correspond with the minimum clinically significant change in pain perception reported by patients.

This prospective, observational study used a VA S to record pain severity among patients reporting pain who were transported to a hospital by paramedics. Patients used a VAS to score pain severity during the initial patient assessment process (T0), and again at the hospital of destination (Tend). This study reports the mean changes in the scores, and the percentage of cases for whom the difference between T0and Tend in the study population achieved or exceeded the 20 mm benchmark. A survey also was administered to paramedics who participated in this study in order to identify attitudes, values, and beliefs relating to the measurement of pain.

A total of 262 patients were enrolled in this study. The mean value for thereduction in VAS (T0-Tend) was 18.2±23.9 mm [±SD] (Median = 14.0mm, 95% confidence interval (CI) = 15.3–21.1 mm). One hundred and thirty-four patients (51.1%) did not receive analgesia (either morphine sulfate or methoxyflurane). The mean initial (T0) pain score for the no-analgesia group was 54.5 ±24.7 mm [±SD], with the mean value for the change in VAS (T0-Tend) = 10.6 mm (median = 5 mm, 95% CI = 6.4–14.8 mm). Fo rty-six patients (17.6%) recorded some deterioration in their pain score at Tend (T0-Tend<0 mm). Survey results identified attitudes that may affect paramedics' pain management practice.

The results suggest that inadequate analgesia is an issue in this study setting. Effective analgesia requires formal protocols or guidelines supported by effective analgesic therapies along with education that addresses attitudes that may inhibit pain assessment or management by paramedics. Regular audits form part of clinical quality assurance programs that assess analgesic practice. However, such auditsmust have access to data obtained from patient self-reporting of pain using a valid and reliable pain measurement tool.

Little has been reported regarding the minimum conditions, information, and knowledge essential for dispatching nurses to join in sudden-onset disaster events from the viewpoint of nurses. This paper explores the issues and concerns that nurses faced when asked to respond to the 1995 Great Hanshin-Awaji Earthquake event in Japan.

A standardized written survey tool was developed using input from four nurses who had responded to the disaster event. Questionnaires that included both “yes” and “no” answers and multiple-choice answers were developed and sent to 823 nurses who worked in four hospitals.

A total of 477/823(58.0%) questionnaires were completed and returned. Of the respondents to the questionnaire, 309 (62.1%) were qualified nurses, and 148 (37.9%) were students. Sixty-nine (15%) of the total 477 respondents participated in the disaster response to the Great Hanshin-Awaji Earthquake. Primary among respondents' concerns were that they should wait for their superiors or institutions to direct them to go “somewhere” and to do “something” and how far away from home would they be required to travel. Home responsibilities conflicting with disaster response were a common concern for respondents.

Managers should consider including the following conditions in disaster dispatch plans: (1) the dispatches should be made part of nursing duties; (2) the disaster plan should be constructed with organizations near disaster sites; and (3) clear directions regarding destination and expected activities should be provided to nurses.

Stress debriefing following exposure to a critical incident isbecoming more prevalent. Its aim is to prevent or minimize the development of excessive stress response symptoms that lead to loss of productivity or effectiveness in the workplace or at home. There is little evidence that any form of psychological debriefing is effective. This study evaluated the effectiveness of three intervention strategies, and attempted to correlate the symptoms with the severity of the incidentand level of intervention.

A randomized, controlled trial of three levels of critical stress intervention was conducted in the British Columbia Ambulance Service (BCAS), in British Columbia, Canada, among paramedics and emergency medical technicians (EMTs), reporting critical incident stress. Outcomes were measured at one week (Stanford Acute Stress Reaction Questionnaire (SASRQ), the Life Impact Score (LIS), and Schedule of Recent Events (SRE)), and at three months and six months following the intervention (Impact of Events (IE), Coping Mechanisms, LIS, and SRE).

Fifty calls were received during the 26-month study period (<1 per 10,000 BCAS response calls): 23 were by third parties, but the involved EMT did not call;nine were placed by crew unwilling to participate in the study; 18 subjects enrolled, but six completed no forms. No correlation was found between severity of the incident and scores on the SASRQ, IE, or LIS, or between any of these scores. There was no consistent pattern in the stress scores over time.

Requests for critical incident stress intervention were uncommon. The need for intervention may not be as great as generally is assumed. Further randomized trials, ideally multicenter studies, are indicated.

During the last decades, several humanitarian emergencies have occurred, with an increasing number of humanitarian organizations taking part in providing assistance. However, need assessments, medical intelligence, and coordination of the aid often are sparse, resulting in the provision of ineffective and expensive assistance. When an earthquake with the strength of 7.7 on the Richter scale struck the state of Gujarat, India, during the early morning on 26 January 2001, nearly 20,000 persons were killed, nearly 170,000 were injured, and 600,000 were rendered homeless. This study identifies how assigned indicators to measure the level of health care may improve disaster preparedness and management, thus, reducing human suffering.

During a two-week mission in the disaster area, the disaster relief provided to the disaster-affected population of Gujarat was evaluated. Vulnerability due to climate, geography, culture, religion, gender, politics, and economy, as each affected the outcome, was studied. By assigning indicators to the eight ELEMENTS of the Primary Health Care System as advocated by the World Health Organization (WHO), the level of public health and healthcare services were estimated, an evaluation of the impact of the disaster was conducted, and possible methods for improving disaster management are suggested. Representatives of the major relief organizations involved were interviewed on their relief policies. Strategies to improve disaster relief, such as policy development in the different aspects of public health/primary health care, were sought.

Evaluation of the pre-event status of the affected society revealed a complex situation in a vulnerable society with substantial deficiencies in the existing health system that added to the severity of the disaster. Most of the civilian hospitals had collapsed, and army field hospitals provided medical care to most of the patients under primitive conditions using tents. When the foreign field hospitals arrived 5 to 7 days after the earthquake, most of the casualties requiring surgical intervention already had been operated on. Relief provided to the disaster victims had reduced quality for the following reasons: (1) proper public health indicators had not yet been developed; (2) efficient coordination was lacking; (3) insufficient, overestimated, or partly irrelevant relief was provided; (4) relief was delayed because of bureaucracy; and (5) policies on the delivery of disaster relief had not been developed.

To optimize the effectiveness of limited resources, disaster preparedness and the provision of feasible and necessary aid is of utmost importance. An appropriate, rapid, crisis intervention could be achieved by continual surveillance of the world's situation by a Relief Coordination Center. A panel of experts could evaluate and coordinate the international disaster responses and make use of stored emergency material and emergency teams. A successful disaster response will depend on accurate and relevant medical intelligence and socio-geographical mapping in advance of, during, and after the event(s) causing the disaster. More effective and feasible equipment coordinated with the relief provided by the rest of the world is necessary. If policies and agreements are developed as part of disaster preparedness, on international, bilateral, and national levels, disaster relief may be more relevant, less chaotic, and easier to estimate, thus, bringing improved relief to the disaster victims.
