Although several studies link job-related stressors with adverse reactions among emergency medical technicians (EMTs), more standardized research is needed, since much remains unknown about stress responses, coping styles and their consequences for EMTs. This paper presents the results of two studies. Study I investigated the relation between job-related stressors, job satisfaction, and psychological distress, while Study II investigated how coping is related to occupational burnout, job-related stress, and physiological arousal.

Study I: Those EMTs experiencing greater job-related stressors are less satisfied with their jobs and more psychologically distressed.

To obtain preliminary information about which coping strategies are associated with greater feelings of stress and burnout and more intense autonomic nervous system reactivity.

For both studies, EMTs from a large, urban, public EMS organization in the southern United States were asked to participate. Study I: Subjects completed an informed consent document, a demographics questionnaire, a measure of job stress (the Stress Diagnosis Inventory), a measure of job satisfaction (Job-in-General), and a measure of psychological symptomatology (Symptom Checklist-90, Revised). Pearson product-moment correlations were computed between the measures. Study II: Subjects completed an informed consent document, a demographics/information sheet, the Maslach Burnout Inventory (MBI), and the Ways of Coping Scale (WOCS). They then completed 30 days of monitoring using the Daily Stress Inventory (DSI) and the Daily Autonomic Nervous System Response Inventory (DANSRI). Pearson product-moment correlations were computed between the measures.

Study I: Those EMTs who experienced greater job-related stress also were significantly more dissatisfied with their jobs, more depressed, anxious, hostile, and endorsed greater global psychological distress. Study IT. The Depersonalization subscale on the MBI correlated significantly with the following WOCS subscales: Accepting Responsibility, Confrontive Coping, Distancing, and Escape/Avoidance. Emotional Exhaustion on the MBI correlated significantly with Confrontive Coping, Escape/Avoidance, and Social Support, while data obtained on the 40 subjects who completed the daily monitoring revealed that DSI-Impact, DANSRI-Number, and DANSRI-Impact scores each correlated significantly with Accepting Responsibility, Confrontive Coping, and Escape/Avoidance.

A significant portion of an EMT's job satisfaction and psychological well-being is associated with the degree to which they are experiencing job-related stress, and, furthermore, this distress level appears to be clinically elevated. This implies that in-service programs and psychological support services designed to help EMTs manage their job-related stress may improve job satisfaction and decrease psychological distress. The coping styles most consistently associated with maladaptive outcomes were: Accepting Responsibility, Confrontive Coping, and Escape/Avoidance. Thus, subjects who were more likely to handle stress with self-blame, aggression, hostility, and risk taking or with wishful thinking, escape tendencies, and avoidance were more likely to endorse more negative outcomes.

The pressures facing emergency medical services (EMS) in Wisconsin and their effects on the delivery of prehospital emergency medical care were not known by the Wisconsin EMS Board. In an effort to assess these pressures and the needs of the emergency medical services in the State as perceived by the services, the Board undertook a survey of the EMS providers in Wisconsin.

A survey instrument was developed and approved by the EMS Board and distributed to all of the licensed emergency medical services in Wisconsin.

Of the 453 survey instruments distributed, 323 (71.3%) were completed and returned. Intermediate- and paramedic-level services were more likely to respond than were the basic services, but 235 (72.8%) of the respondents identified their service levels as basic. In addition to providing information about the service characteristics, each responding service also rated the importance of their perceived needs. Lack of medical direction was perceived as the greatest need by all levels of service. However, the second greatest area of need for basic and intermediate services related to difficulty in recruiting new staff. For paramedic services, the second greastest need was associated with dispatching. When comparing services by rural versus urban, difficulty in recruiting new staff and collecting ambulance fees were seen as second and third to lack of a medical director by rural services, whereas urban services noted local training to be in the top three. In the assessment of educational needs, patient-care issues dominated. A review of written comments also demonstrated a difference between rural and urban services, but both noted Medicare and Medicaid reimbursement issues more commonly than any other problem.

In the restructuring of health care, it will be important to consider the various needs of prehospital providers and recognize that such needs may be unique to the providers' location and level of service.

The majority of prehospital emergency medical services (EMS) personnel lack specific training relating to elder abuse and neglect.

To develop and test an audio visual training program that focuses on the identification and reporting of domestic violence in the elderly.

A videotape was designed to be used as a 45-minute training course for prehospital personnel using one-half inch, super-VHS recording. A convenience sample of 60 EMS personnel working in Kent County then were asked to evaluate the videotape program. Each volunteer completed a pre-test on elder abuse and neglect, watched the 45-minute videotape, and then answered 12 questions on a post-test.

Participants had an average of 12.4 years (range: 1–30 years) prehospita emergency-care experience. Only four (7%) could recall any previous training relating to elder abuse or neglect during their career. Although the prevalence of elder abuse in their community was described as “rather rare” by most (60%) of the subjects, 85% (51/60) had seen a suspected case of elder abuse or neglect during their careers; 47% (28/60) had seen a case during the past six months. Only 29% of these suspected cases were reported to county authorities. Approximately 40% of the questions on the pre-test were answered correctly (mean score, 4.8 ± 3.0). In comparison, 83% of the questions on the post-test were answered correctly (10.0 ± 3.0). Although participants had a number of suggestions to improve the video program, 78% (47/60) expected this material to change the way they will evaluate elderly patients in the future.

Prehospital personnel do not feel confident identifying or reporting victims of elder abuse or neglect. A videotape training program may be an effective way of presenting this information as a means of continuing education.

Emergency medical vehicle collisions (EMVCs) occurring during initia response and with patient transport have been a long-standing problem for emergency medical services (EMS) systems. Experience suggests “wake-effect” collision occur as a result of an EMS vehicle's transit, but do not involve the emergency medical vehicle (EMV). Substantiating the existence and magnitude of wake-effect collisions may have major implications regarding the manner of EMV response.

Paramedics will report that wake-effect collisions do occur and that the occur more frequently than do EMVCs.

Design: Survey analysis. Participants: Thirty paramedics employed by the Salt Lake City (Utah) Fire Department and 45 paramedics employed by Salt Lake County Fire Department. Geographic Area: Service area has population of 650,000 and is urban, suburban, and rural. Measurements: The survey consisted of three openended questions concerning years on the job, EMVCs, and wake-effect collisions. Analysis: The mean value for the number of EMVCs and wake-effect EMVCs, along with the 0.95 confidence intervals (0.95 CI) were determined.

Seventy-three surveys were analyzed. Sixty EMVCs and 255 wake-effect collisions were reported. Overall, the mea value for the number EMVCs per respondent was 0.82 (0.60–1.05) and for wake-effect collisions 3.49 (2.42–4.55). The mean values for EMVC's for each service were 0.86 (0.50–1.38); 0.80 (0.50–11.0). For wake-effect collisions the mean values were 4.59 (2.83–6.35); and 2.76 (1.46–4.06) respectively.

This study suggests that the wake-effect collision is real and may occur with greater frequency than do EMVCs. Significant limitations of this study are recall bias and misclassiftcation bias. Future studies are needed to define more precisely wake-effect collision prevalence and the resulting “cost” in regards to injury and vehicle/property damage.

Patients refusing hospital transportation occurs in 5% to 25% of out-of-hospital calls. Little is known about these calls. This study was needed to determine the demographics, inherent risks, and timing of refused calls.

This was a prospective review of all run sheets of patients who refused transportation were collected for a two month period. Demographic data and medical information was collected. Each run was placed into one of three categories of need for transport and further evaluation: 1) minimal; 2) moderate; and 3) definite. The Greater Elgin Area Mobile Intensive Care Program (GEA-MICP) based at Sherman Hospital in Elgin, Illinois, was the setting. The GEA-MICP is an Emergency Medical Services (EMS) system comprised of 17 advanced life support (ALS) ambulance agencies servicing northeastern Illinois. Study subjects were all patients who refused transportation to a hospital by ALS ambulance during July 1993 and February 1994. Paramedics were required to complete a run sheet for all calls.

Overall, 30% (683 of2,270) of all runs resulted in refusal of transportation. Patients who most commonly refused transportation were asymptomatic, 11–40 years old and involved in a motor vehicle crash. They usually had no past medical history, normal vital signs, and a normal mental status. Patients generally signed for their own release after evaluation. The average time to arrival was 4.2 minutes and average time spent on scene by paramedics was 18.4 minutes. Of the patients, 72% were judged to have minimal need, 25% were felt to have a moderate need, and 3% were felt to definitely need transport to a hospital for further evaluation and/or treatment.

There are many cases when EMS are activated, but transportation is refused. Most refusals occur after paramedic evaluation. Providing paramedics with primary care training and protocols would standardize care given to patients and provide a mechanism for discharge instructions and follow-up for those who chose not to be transported to a hospital. Patients judged to require further treatment had unique characteristics. These data may be useful in identifying potentially sicker patients allowing a concentrated effort to transport this subset of patients to a hospital.

To describe the use of the Automatic External Defibrillation (AED) device in an urban, two-tiered Emergency Medical Service (EMS) response setting with regard to its potential effects on cardiac arrest patient survival and neurologic outcome.

A retrospective and descriptive design was utilized to study all cardiac arrest patients that had resuscitations attempted in the prehospital environment over a 30-month period. The study took place in a two-tiered EMS system serving an urban population of 368,383 persons. The first tier of EMS response is provided by the City Fire Department, which is equipped with a standard AED device. All first-tier personnel are trained to the level of Emergency Medical Technician-Basic. The second tier of EMS response is provided by personnel from one of two ambulance services. All second-tier personnel are trained to the level of Emergency Medical Technician-Paramedic.

271 cardiac arrest patients were identified for inclusion. One-hundred nine of these patients (40.2%) had an initial rhythm of either ventricular fibrillation or pulseless ventricular tachycardia and were shocked using the AED upon the arrival of first-tier personnel. Forty-two patients (38.5%) in this group had a return of spontaneous circulation in the field and 22 (20.2%) survived to hospital discharge. Of the survivors, 17 (77.3%) had moderate to good neurologic function at discharge base on the Glasgow-Pittsburgh Cerebral Performance Categories. Faster response times by the first-tier personnel appeared to correlate with better neurologic outcomes.

First responder-based AED usage on patients in ventricular fibrillation or pulseless ventricular tachycardia can be applied successfully in an urban setting utilizing a two-tiered EMS response. In this study, a 20.2% survival to hospital discharge rate was obtained. Seventy-seven percent of these survivors had a moderate to good neurologic outcome based on the Glasgow-Pittsburgh Cerebral Performance Categories.

This study examines those factors predictive of self-perceived first-aid abilities among a community-based sample after the 1994 Northridge earthquake.

A probabilities-proportionate to-size (pps) sample of residents of Los Angeles County and 11 pre-selected zip codes from southeastern Ventura County was selected using computer-generated random digit-dialing (rdd) procedures 7–11 months after the earthquake. Data were collected from 506 individuals in 45 minute interviews. A unidimensional scale of self-perceived first-aid ability was created and represents the dependent variable in a causal path model.

In a causal path model, standardized path coefficients suggested that while reports of taking first-aid courses were the most influential factors in predicting higher self-perceived first-aid abilities, other factors including being white, younger, speaking English in the home, and lower income also predicted higher self-perceived first-aid abilities that were independent from taking formal first-aid courses.

First-aid training should be directed towards target segments of the population that are not likely to have had instruction in these basic skills. Those individuals who self-report high first-aid proficiency, independent of formal first-aid training, should be evaluated to assess their abilities to perform these skills.

The raw number of hospital trauma beds and occupancy has been used assess the surgical capability of hospitals in wartime and disaster situations. The goal of this study was to examine and offer a better tool to determine the load of casualties that a hospital would be able to absorb and treat effectively during these situations.

Simulation software was applied to various wartime scenarios. It assessed the usefulness of a computerized simulation of operating room (OR) function under loading of “standard wartime casualties.” Comparison of the functioning of similar hospitals was undertaken in order to identify possible methods to optimize the care delivered. A “what-if” module was used to define the optimal way to absorb mass casualties within the known resources of a given healthcare system. Each hospital was tested under different loading of “standard casualties.” Average waiting time for surgery was used as a marker of the constant decay in the standards of care with the increasing patient load.

Different, unique patterns of strategies for optimizing waiting periods were identified. Not all trauma centers responded by shortening waiting time by diverting the lightly injured patients from them either before or after triage. The reaction to alternate days' shift was unexpected The temporal course of matching a patient with a functional operating room was more indicative of a hospital's capability to absorb casualties requiring surgery than was the pre-set number of beds available in the hospital.

The use of simulation techniques might be useful method to asses the nationwide surgical capability. This is a complex dilemma that cannot be predicted with trivial guessing, even when combined with previous experience of triaging. Analyzing the weak points and bottlenecks at a national level might help in creating preparedness protocols.

The purpose of this study was to critically review the provision of medical care at mass gatherings as described in 25 years of case reports. Specifically measured was the relationship between the size of a mass gathering and the frequency of patients seeking medical aid and the effects of certain event characteristics on this relationship.

Data were obtained through a retrospective literature review. Medline and CINHAL computerized databases were searched for English language articles using several keywords: “mass gathering”, “concert”, “festival”, “Olympics”, “crowd”, “riot”, “stadium”, “sports”, “games”, “papal”, and “football”. Only articles containing complete information on the number of spectators, number of patients, type, location, and duration of the mass gathering were included in the primary analysis. As available, additional information was added including the described weather patterns, number of patients transported to a hospital, and number of patients suffering a cardiac arrest. Thirty-five of the approximately 100 articles reviewed, met these criteria.

A Spearman Rank Correlation Coefficient was calculated for number of spectators and patients and a significant relationship was identified (p = 0.0001). Mann-Whitney U-tests indicated that papal masses (p = 0.04), rock concerts (p = 0.005), hot climatic conditions (p = 0.03) and events held in the British Commonwealth (p = 0.03) had a significantly higher frequency of patient visits. Significantly more cardiac arrests occurred at papal masses (p = 0.04) and sporting events (p = 0.0002).

Type of event, country, weather, and the size of the mass gathering had a significant effect on the numbers of spectators seeking medical care. A uniform classification scheme is necessary for future prospective studies of mass gatherings.
