During disasters, public health departments assume the role of maintaining the health of displaced persons. Displaced persons arrive with acute and chronic conditions as well as other risk factors. Descriptions of these conditions may aid future shelter planning efforts.

Approximately 4,000 individuals from New Orleans, displaced by Hurricane Katrina, were sheltered in Austin, Texas. A stratified random sample of the population was selected using individual beds as the primary sampling unit. Adults were interviewed about their acute symptoms, chronic diseases, and other risk factors.

The results indicate a substantial proportion of adults arrived with some symptoms of acute illness (49.8%). A majority of the adults reported living with a chronic condition (59.0%), and the prevalence of some chronic conditions was higher than that of the general population. Also, several factors that could complicate service delivery were prevalent.

Acute illnesses present transmission risks within the shelter. Furthermore, chronic diseases must be managed and may complicate care of acute illnesses. Risks like activity limitation or substance abuse may complicate shelter operations. Defining the potential scope of the illness burden may be used to help public health departments better plan the services they must deliver to displaced populations.

During October and November 2005, the National Norwegian Tsunami Support Association organized a journey to the disaster area for survivors. The aim of this study was to investigate whether the Tsunami affected the participants' psychological problems.

Twenty-nine adults and 19 children made the journey. Steps were taken to enable each individual to acquire an overall understanding of the catastrophic event. Various forms of antiphobic training were provided. At the end of the stay, 28 adults replied to a questionnaire. The questions concerned: (1) motives for traveling; (2) benefits experienced; (3) psychological problems before departure; and (4) problems at the end of the stay. Parents with children were asked to assess their children's psychological problems at the same points in time.

Considerable improvements in anxiety symptoms were reported and observed in both the adults and children. No certain cases of retraumatization occurred.

The improvements can be understood in the light of psychodynamic, cognitive, and behavioral theory approaches. The duration of the improvement in symptoms remains to be documented. There appears to be grounds for encouraging traumatized patients to return to a disaster area as part of the treatment process if they so wish.

Disaster preparedness is an area of major concern for the medical community that has been reinforced by recent world events. The emergency healthcare system must respond to all types of disasters, whether the incidents occur in urban or rural settings. Although the barriers and challenges are different in the rural setting, common areas of preparedness must be explored.

This study sought to answer several questions, including: (1) What are rural emergency medical services (EMS) organizations training for, compared to what they actually have seen during the last two years?; (2) What scale and types of events do they believe they are prepared to cope with?; and (3) What do they feel are priority areas for training and preparedness?

Data were gathered through a multi-region survey of 1,801 EMS organizations in the US to describe EMS response experiences during specific incidents as well as the frequency with which these events occur. Respondents were asked a number of questions about local priorities.

A total of 768 completed surveys were returned (43%). Over the past few years, training for commonly occurring types of crises and emergencies has declined in favor of terrorism preparedness. Many rural EMS organizations reported that events with 10 or fewer victims would overload them. Low priority was placed on interacting with other non-EMS disaster response agencies, and high priority was placed on basic staff training and retention.

Maintaining viable, rural, emergency response capabilities and developing a community-wide response to natural or man-made events is crucial to mitigate long-term effects of disasters on a local healthcare system. The assessment of preparedness activities accomplished in this study will help to identify common themes to better prioritize preparedness activities and maximize the response capabilities of an EMS organization.

In Australia, cardiac arrest kills 142 out of every 100,000 people each year; with only 3–4% of out-of-hospital patients with cardiac arrest in Melbourne surviving to hospital discharge. Prompt initiation of cardiopulmonary resuscitation (CPR), defibrillation, and advanced cardiac care greatly improves the chances of survival from cardiac arrest. A critical step in survival is identifying by the emergency ambulance dispatcher potential of the probability that the person is in cardiac arrest. The Melbourne Metropolitan Ambulance Service (MAS) uses the computerized call-taking system, Medical Priority Dispatch System (MPDS), to triage incoming, emergency, requests for ambulance responses. The MPDS is used in many emergency medical systems around the world, however, there is little published evidence of the system's efficacy.

This study attempts to undertake a sensitivity/specificity analysis to determine the ability of MPDS to detect cardiac arrest.

Emergency ambulance dispatch records of all cases identified as suspected cardiac arrest by MPDS were matched with ambulance, patient-care records and records from the Victorian Ambulance Cardiac Arrest Registry to determine the number of correctly identified cardiac arrests. Additionally, cases that had cardiac arrests, but were not identified correctly at the point of call-taking, were examined. All data were collected retrospectively for a three-month period (01 January through 31 March 2003).

The sensitivity of MPDS in detecting cardiac arrest was 76.7% (95% confidence interval (CI): 73.6%–79.8%) and specificity was 99.2% (95% CI: 99.1–99.3%). These results indicate that cardiac arrests are correctly identified in 76.7% of cases.

Although the system correctly identified 76.7% of cardiac arrest cases, the number of false negatives suggests that there is room for improvement in recognition by MPDS to maximize chances for survival in out-of-hospital cardiac arrest. This study provides an objective and comprehensive measurement of the accuracy of MPDS cardiac-arrest detection in Melbourne, as well as providing a baseline for comparison with subsequent changes to the MPDS.

Over-triage of patients by emergency medical services (EMS) dispatch is thought to be an acceptable alternative to under-triage, which may delay how quickly life-saving care reaches a patient. Previous studies have looked at advanced life support (ALS) misutilization in urban- and county-based EMS systems and have attempted to analyze how dispatch methods either contribute to or alleviate this problem.1–5

The purpose of this study is to assess the relationship between dispatches of a cardiac nature in a Medical Priority Dispatch (MPD) system, and the actual clinical diagnosis as determined by an emergency department physician.

Calls for emergency medical assistance in a suburban community outside of a major metropolitan area were surveyed over a three-month period. Medical Priority Dispatch protocols determined that 104 of these calls were cardiac-related. Of these emergency calls, 56 (53.8%) patients were transported to the local community hospital and treated by the emergency physician. A retrospective review of the medical records was conducted to determine whether the patient had a cardiac-related discharge diagnosis from the emergency department.

Sixteen (28.6%) of the patients in this cohort were diagnosed with a cardiac-related condition upon discharge from the emergency department. Forty (71.4%) were diagnosed with a non-cardiac-related condition. The positive, predictive value of the dispatch protocol for the detection of an actual cardiac emergency in this EMS system was 28.6%.

In this suburban community, the MPD system may over-triage emergency medical responses to cardiac emergencies. This can result in the only ALS (paramedic) unit in the community being unavailable in certain situations. Future studies should be conducted to determine what level (in any) of over-triage is appropriate in EMS systems using a MPD system.

Understanding ambulance utilization patterns is essential to assessing prehospital system capacity and preparedness at the national level.

To describe the characteristics of patients transported to US emergency departments (EDs) by ambulance and to determine predictors of ambulance utilization.

Data were obtained from the National Hospital Ambulatory Medical Care Survey using mode of arrival, demographic and visit information, ICD-9-CM E and V-codes, and classified reasons for the visit.

The rates for ED visits of persons conveyed by ambulence were stable between 1997 and 2003, consisting of approximately one in every seven ED visits (14%). In 2003, there were 16.2 million ED visits for which an ambulance was used in the US. However, for patients with mental health visits, nearly one in three ED presentations (31%) arrived by ambulance. Significantly higher rates of ambulance use were associated with: (1) mental health visits; (2) older age; (3) African-Americans; (4) Medicare or self-pay insurance status; (5) urban ED location; (6) US regions outside of the South; (7) presentation between 12 midnight to 0800 hours; (8) injury-related visits; (9) urgent visit status; and/or (10) those resulting in hospital admission. Among mental health patients, older age, self-pay insurance status, urban ED location, regions outside the southern US, and urgent visit classification predicted ambulance use. Ambulance usage within the mental health group was highest for suicide and lowest for mood and anxiety disorder-related visits.

Reliance on ambulance services varies by age, insurance status, geographic factors, time of day, urgency of visit, subsequent admission status, and type of mental health disorder. Even after controlling for many confounding factors, mental health problems remain an important predictor of ambulance use.

Collegiate-based emergency medical systems (CBEMS) are a unique model for the delivery of prehospital care. The National Collegiate Emergency Medical Services Foundation (NCEMSF) was founded to serve as a resource for CBEMS groups. The purpose of this investigation is to describe the current state of CBEMS organizations.

The NCEMSF maintains a Web-based, data collection system to gather data on CBEMS organizations. Collegiate-based emergency medical services are defined as emergency medical services in a university or college campus setting. The abstracted data from the NCEMSF registry were analyzed using descriptive statistics.

The NCEMSF registry contained data on 175 groups, and 145 groups were identified as providing CBEMS. The levels of service provided by the groups were: (1) first responder, 8.3%; (2) basic life support (BLS) 66.2%; (3) intermediate life support (ILS) 4.8%; (4) advanced life support (ALS), 9.7%; and (5) combination BLS/ALS, 8.3%. Transport capabilities were provided by 31.7% of the CBEMS. The average response time was estimated at 2.6 minutes (95% confidence interval (CI), 2.35–2.91 minutes). Early defibrillation using a automated external defibrillator (AED) or ALS was available by 75.9% (95% CI, 68.8–83.0) of CBEMS. Service to the community beyond the campus was provided by 21.3% of CBEMS groups. Forty-eight percent of the services operate 24 hours/day, seven days/week. The average call volume per year was 568 responses (95% CI, 315–820), and the groups averaged 29 (95% CI, 25–34) members. During the past five years, an average of 4.3 new CBEMS groups were formed per year. Eleven of the CBEMS are based at international schools.

Previous studies have proven the success of the EsophagealTracheal Combitube (ETC) as a primary airway, but not as a rescue airway.

The object of this study was to observe success and complication rates of paramedic placement of an ETC as a rescue airway, and to compare success rates with endotracheal tube (ETT) intubation. The primary outcome indicator was placement with successful ventilation. Complication rates, esophageal placement, and return of spontaneous circulation (ROSC) were secondary measures.

A retrospective review of the records of patients who had ETC attempts by Emergency Medical Services (EMS) was conducted for a period of three years. Complications were defined a priori. The ETC is used primarily as rescue airway for a failed attempt at an endotracheal tube (ETT) intubation. A control group for ETT placements was drawn from the EMS quality assurance (QA) database for the same period.

Esophageal-Tracheal Combitube insertion was attempted on 162 patients, of which, 113 (70%) were successful, 46 (28%) failed, and the outcome of three (2%) was not recorded. Inability to place the ETC occurred in 29 (18%) patients, and accounted for 48% (22/46) of failures. The use of the ETC caused dental trauma in one patient, and one placement of the ETC was related to the onset of subcutaneous emphysema. Blood in the ETC from active upper gatrointestinal bleeding occurred in nine patients (6%), and four tubes (3%) became dislodged en route to the hospital. The a priori complication rate was 44/162 (27%). Inability to determine placement of the ETC due to emesis from both ports occurred in 21 cases. Combining these problems with the a priori complications, the overall rate was 40% (65/162). EsophagealTracheal Combitube location was noted in a subset of 90 charts, of which, 76 (84%) were esophageal, and 14 (16%) were tracheal. Thirteen of 126 (10%) patients in cardiac arrest had return of spontaneous circulation (ROSC) in the field after placement of the ETC. An ETT was attempted in 128 control patients, of which, 107 (84%) were successful, 21 (16%) failed (odds ratio (OR) for ETT vs. ETC = 2.1; 95% CI = 1.12–3.86).

Despite a low ROSC rate, the complication and success rates of ETC are acceptable for a rescue airway device. Tracheal placement of the Combitube is uncommon, but requires fail-safe discrimination. Similar to previous reports, the success ratio for ETT was greater than for the ETC.

Aspirin is administered to patients with acute coronary syndromes (ACSs), but prehospital providers do not administer aspirin to all patients with chest pain that could be secondary to an ACS.

To identify reasons prehospital providers fail to administer aspirin to all patients complaining of chest pain.

A convenience sample of prehospital providers was surveyed as they transported patients with a chief complaint of chest pain to the emergency department. The providers were asked if they had given aspirin, nitroglycerin, or oxygen, or if they utilized a monitor. If the medications had not been administered, the paramedic was asked about the reason. The patient's age and previous cardiac history also was recorded.

A total of 52 patients with chest pain who were transported were identified over eight weeks, and all of the providers agreed to participate in the study. Only 13 of the patients (25%) received aspirin. Reasons given for not administering aspirin to the other 39 patients included: (1) chest pain was not felt to be cardiac in 13 patients (33%); (2) 10 patients already had taken aspirin that day (26%); (3) the medical provider was a basic-level emergency medical technician (EMT)-Basic and could not administer aspirin to six patients (15%); (4) pain subsided prior to arrival of emergency medical services (EMS) in these three patients; and (5) other reasons were provided for the remaining seven patients.

The most common reason that paramedics did not administer aspirin was the paramedic's belief that the chest pain was not of a cardiac nature. Another common reason for not giving aspirin was the inability of EMT-Basic providers to administer aspirin.

Mexico City has one of the highest mortality rates in Mexico, with non-intentional injuries as a leading cause of death among persons 1–44 years of age. Emergency medical services (EMS) in Mexico can achieve high levels of efficiency by offering high quality medical care at a low cost through adequate system design.

The objective of this study was to determine whether the prehospital EMS system in Mexico City meets the criteria standards established by the American Ambulance Association Guide for Contracting Emergency Medical Services (AAA Guide) for highly efficient EMS systems.

This retrospective, descriptive study, evaluated the structure of Mexico City's EMS system and analyzed EMS response times, clinical capacity, economic efficiency, and customer satisfaction. These results were compared with the AAA guide, according to the social, economic, and political context in Mexico. This paper describes the healthcare system structure in Mexico, followed by a description of the basic structure of EMS in Mexico City, and of each tenet described in the AAA guide. The paper includes data obtained from official documents and databases of government agencies, and operative and administrative data from public and private EMS providers.

The quality of the data for response times (RT) were insufficient and widely varied among providers, with a minimum RT of 6.79 minutes (min) and a maximum RT of 61 min. Providers did not define RT clearly, and measured it with averages, which can hide potentially poor performance practices. Training institutions are not required to follow a standardized curriculum. Certifications are the responsibility of the individual training centers and have no government regulation. There was no evidence of active medical control involvement in direct patient care, and providers did not report that quality assurance programs were in place. There also are limited career advancement opportunities for EMS personnel. Small economies of scale may not allow providers to be economically efficient, unit hours are difficult to calculate, and few economic data are available.There is no evidence of customer satisfaction data.

Emergency medical services in Mexico City did not meet the AAA requirements for high-quality, prehospital, emergency care. Coordination among EMS providers is difficult to achieve, due, in part, to the lack of: (1) an authoritative structure; (2) sound system design; and (3) appropriate legislation. The government, EMS providers, stakeholders, and community members should work together to build a high quality EMS system at the lowest possible cost.

A growing number of golfers are senior citizens, and it may be predicted that the number of golf-related medical emergencies, including the incidence of cardiac arrest, will increase. This study was designed to survey the level of preparedness of golf courses in Southeastern Pennsylvania to respond to cardiac arrest among their members.

A telephone survey of all of the 180 golf courses in the area was conducted to determine their type (public/private), volume in rounds per year, presence of automated external defibrillator (AED) devices, number of employees, and percentage of employees with cardiopulmonary resuscitation (CPR) training. Participants also were asked to estimate the time needed to reach the farthest point on their course in order to estimate a maximum time to the application of an AED device.

A total of 131 of 180 golf courses completed the survey (53 private, 78 public) for an overall response rate of 73%. Private courses reported a greater average number of employees with CPR training [private = 9.1, public = 3.6; p = 0.001] and in AED presence [public = 9%, private = 58.5%; p = 0.0001]. Public courses support a higher volume of play than do private courses [public = 32,000, private = 24,000; p = 0.001], yet have far fewer employees [public = 25, private = 44; p = 0.004]. The longest time necessary to reach the most remote point on the course was between four and five minutes in all courses. Analysis was performed using the Student's t-test and Pearson's Chi-square as appropriate.

Neither public nor private golf courses are well equipped to respond to cardiac arrest, but outcomes on public courses likely are to be far worse.
