The development of international emergency medicine: a role for U.S. emergency physicians and organizations. SAEM International Interest Group

There is a rapidly growing interest in emergency medicine (EM) and emergency out-of-hospital care throughout the world. In most countries, the specialty of EM is either nonexistent or in an early stage of development. Many countries have recognized the need for, and value of, establishing a quality emergency health care system and are striving to create the specialty. These systems do not have to be high tech and expense but can focus on providing appropriate emergency training to physicians and other health care workers. Rather than repeatedly "reinventing the wheel" with the start of each new emergency care system, the preexisting knowledge base of EM can be shared with these countries. Since the United States has an advanced emergency health care system and the longest history of recognizing EM as a distinct medical specialty, lessons learned in the United States may benefit other countries. In order to provide appropriate advice to countries in the early phase of emergency health care development, careful assessment of national resources, governmental structure, population demographics, culture, and health care needs is necessary. This paper lists specific recommendations for EM organizations and physicians seeking to assist the development of the specialty of EM internationally.     

Analysis of factors affecting U.S. emergency physician workforce projections. SAEM Workforce Task Force

OBJECTIVES: To use existing data sources to refine prior estimates of the U.S. emergency medicine (EM) workforce and to estimate effects of proposed changes in the U.S. health care system on the EM workforce. METHODS: Relevant data were extracted from the American College of Emergency Physicians (ACEP) 1995 Membership Activity Report, the American Medical Association (AMA) publication "1995/96 Physician Characteristics and Distribution in the U.S.," the American Hospital Association (AHA) 1994 hospital directory, a written survey of each state's medical licensing board and state medical society, and the American Board of Emergency Medicine (ABEM) annual activity report for 1995. These data were used to project workforce supply and demand estimates applicable to workforce models. RESULTS: None of the available information sources had complete data on the number and distribution of emergency physicians (EPs) currently practicing in the United States. Extrapolating the limited reliable statewide EP numbers to make nationwide projections reveals a shortage of EPs needed to fully staff the nation's existing EDs. At least 22 states had an average ratio of < 5 EPs per existing ED. Additional national projections incorporating a decreasing number of U.S. EDs indicate that the current annual number of EM residency graduates will not eliminate the deficit of EPs for at least several decades, given that projected numbers of retiring EPs annually will soon equal the total annual EM residency graduate production. CONCLUSIONS: Although the current data on EPs in practice in the United States are incomplete, the authors project a relative shortage of EPs. More accurate and complete information on the numbers and distribution of EPs in America is needed to improve workforce projections.     

Precisely defining high-risk operable head and neck tumors based on RTOG #85-03 and #88-24: targets for postoperative radiochemotherapy?

OBJECTIVE: In the German physician-based emergency medical system (EMS) psychiatric emergency situations (PES) rank on third place contradictory to it's importance during emergency physician training program. The aim of our study was to examine the relevance of PES and the stress which PES imposes upon EMS physicians. Further, the interest of training programs on that issue was determined. Knowledge about PES was investigated by a short test. METHODS: 952 emergency physicians were sent a questionnaire about following: demographic data, frequency of PES, strain by PES, own knowledge, interest about training programs. Further five typical PES were presented for diagnostic and therapeutic judgement. RESULTS: 222 responded (183 men/37 women/2 without gender data, average age: 40.1 +/- 6.7, qualification as emergency physician: 9.6 +/- 5.1 years, most frequent subspeciality in-hospital physicians: anaesthesiology 67.5%, in-practice physicians: general medicine 72.1%). PES frequence was estimated at 9.4%, personal knowledge judged only by 13% as sufficient, 14.2 felt incapable by PES. 73% saw importance of training, especially expressed by the more experienced (P < 0.05). Test presented 65% correct diagnoses, 33% correct therapy, 26% incorrect decision of hospital admission. CONCLUSION: PES are a frequent problem of pre-hospital patient care for emergency physicians. As personal knowledge was estimated to be insufficient, the interest for courses concerning PES issues is high.     

Termination of nontraumatic cardiac arrest resuscitative efforts in the field: a national survey

OBJECTIVES: 1) To describe elements of adult nontraumatic cardiac arrest protocols in those U.S. cities in which resuscitative efforts are being terminated in the out-of-hospital setting. 2) To determine the prevalence and methods of on-scene family grief counseling delivered in this setting. METHODS: Emergency medical services (EMS) systems in each of the 200 largest cities in the United States were surveyed by telephone regarding the content of their adult cardiac arrest protocols. Type of arrest (medical vs trauma), final dysrhythmia, termination policies, and presence or absence of a grief counseling protocol were recorded. RESULTS: All of the target population responded to the telephone survey. Most (135; 68%) EMS systems currently have written protocols that allow in-field termination of resuscitative efforts for adult nontraumatic cardiac arrest patients who remain asystolic. Only 47 (24%) EMS systems allow cessation of efforts for patients without return of spontaneous circulation regardless of the dysrhythmia. Base station contact is required for authorization to end resuscitative efforts in 120/135 (89%) EMS systems. Only 26/135 (19%) EMS systems that cease efforts in the field have written policies concerning on-scene family grief counseling. This counseling is most likely to be conducted by the out-of-hospital providers themselves. CONCLUSION: Many U.S. urban EMS systems are terminating efforts for selected adult nontraumatic cardiac arrest patients, although few have written policies to address grief intervention for family members at the scene.     

Ambulatory care visits to physician offices, hospital outpatient departments, and emergency departments: United States, 1996

OBJECTIVE: This report describes ambulatory care visits in the United States across three ambulatory care settings--physician offices, hospital outpatient departments, and hospital emergency departments. Statistics are presented on selected patient and visit characteristics for all ambulatory care visits and separately for each setting. METHODS: The data presented in this report were collected by means of the 1996 National Ambulatory Medical Care Survey (NAMCS) and the 1996 National Hospital Ambulatory Medical Care Survey (NHAMCS). These surveys are part of the ambulatory care component of the National Health Care Survey that measures health care utilization across a variety of providers. The NAMCS and NHAMCS are national probability sample surveys of visits to office-based physicians (NAMCS) and visits to the outpatient departments and emergency departments of non-Federal, short-stay and general hospitals (NHAMCS) in the United States. Sample data are weighted to produce annual estimates. RESULTS: During 1996 an estimated 892 million visits were made to physician offices, hospital outpatient departments, and hospital emergency departments in the United States, an overall rate of 3.4 visits per person. Visits to office-based physicians accounted for 82.3 percent of ambulatory care utilization, followed by visits to emergency departments (10.1 percent) and outpatient departments (7.5 percent). Persons 75 years and over had the highest rate of ambulatory care visits. Females had significantly higher rates of visits to physician offices and hospital outpatient departments than males did. About two-thirds of ambulatory care visits by black persons were to physician offices. There were an estimated 129.3 million injury-related ambulatory care visits during 1996 or 48.9 visits per 100 persons.     

Subretinal semiconductor microphotodiode array

OBJECTIVE: To evaluate the predictive validity of the Emergency Physician Job Satisfaction (EPJS) and Global Job Satisfaction (GJS) instruments. METHODS: Prospective mail survey of 223 Canadian emergency physicians (EPs) using a 42-item questionnaire, including 14 items evaluating their reasons for leaving emergency medicine (EM). Original (1990) EPJS and GJS scores were analyzed using 1-way ANOVA and Scheffe's test comparing the physicians who left EM with those still in their original jobs, and those who had left their original jobs but who stayed in EM. Mean scores on the 14 "reason for leaving" items were compared with scores from an earlier sample of U.S. physicians using a t-test for independent means. Criteria for statistical significance were set at alpha = 0.05 for all analyses. RESULTS: The response rate for the primary study questions was 99.1%. Of the respondents, 29.4% had left their original jobs, and 10.4% had left EM altogether. The GJS scores for the physicians who left EM were significantly different from those for the physicians who stayed (p = 0.004). The EPJS scores for the physicians who left EM were not significantly different from those for the physicians who stayed (p = 0.56). There was no significant difference in scores between the Canadian and U.S. physicians' reasons for leaving EM (all p-values > 0.05). Shiftwork scored the highest as a reason to leave EM. CONCLUSIONS: A low GJS score is associated with physicians' leaving EM, but not with changing jobs. The EPJS instrument was not associated with either outcome. Canadian and U.S. EPs place similar levels of importance on potential reasons for leaving EM.     

Position of the mental foramen in a North American, white population

In Italy departments of emergency medicine and emergency medical service systems (EMS) were first set up at the end of the 1970s. Since that time many dramatic and significant changes have taken place in the care of the critically ill patient. In Italy the interest in emergency problems and the need for emergency intervention have increased considerably. Nevertheless several problems still have to be solved in order to obtain a standardized organization of the emergency system in Italy and uniform training of emergency care providers.     

The principal physician in emergency medicine

The implementation of an experienced pre-hospital care emergency physician as an on the-scene medical command officer (MCO) within the emergency medical service (EMS) is an essential prerequisite to guarantee qualified medical supervision during mass-casuality incidents (MCI). The MCO has four basic functions. Within the administration of the EMS system, he is responsible for the medical aspects of strategic planning for the MCI response. During the MCI the MCO is responsible for the overall assessment of the situation, triage, and supervision of medical treatment by physician and non-physician providers. Aside from extensive personal experience in pre-hospital care, the MCO needs special training to be qualified for this position. State EMS laws provide the legal basis for the MCO within the EMS system.     

Trauma mortality patterns in three nations at different economic levels: implications for global trauma system development

BACKGROUND: Whereas organized trauma care systems have decreased trauma mortality in the United States, trauma system design has not been well addressed in developing nations. We sought to determine areas in greatest need of improvement in the trauma systems of developing nations. METHODS: We compared outcome of all seriously injured (Injury Severity Score > or = 9 or dead), nontransferred, adults managed over 1 year in three cities in nations at different economic levels: (1) Kumasi, Ghana: low income, gross national product (GNP) per capita of $310, no emergency medical service (EMS); (2) Monterrey, Mexico: middle income, GNP $3,900, basic EMS; and (3) Seattle, Washington: high income, GNP $25,000, advanced EMS. Each city had one main trauma hospital, from which hospital data were obtained. Annual budgets (in US$) per bed for these hospitals were as follows: Kumasi, $4,100; Monterrey, $68,000; and Seattle, $606,000. Data on prehospital deaths were obtained from vital statistics registries in Monterrey and Seattle, and by an epidemiologic survey in Kumasi. RESULTS: Mean age (34 years) and injury mechanisms (79% blunt) were similar in all locations. Mortality declined with increased economic level: Kumasi (63% of all seriously injured persons died), Monterrey (55%), and Seattle (35%). This decline was primarily due to decreases in prehospital deaths. In Kumasi, 51% of all seriously injured persons died in the field; in Monterrey, 40%; and in Seattle, 21%. Mean prehospital time declined progressively: Kumasi (102 +/- 126 minutes) > Monterrey (73 +/- 38 minutes) > Seattle (31 +/- 10 minutes). Percent of trauma patients dying in the emergency room was higher for Monterrey (11%) than for either Kumasi (3%) or Seattle (6%). CONCLUSIONS: The majority of deaths occur in the prehospital setting, indicating the importance of injury prevention in nations at all economic levels. Additional efforts for trauma care improvement in both low-income and middle-income developing nations should focus on prehospital and emergency room care. Improved emergency room care is especially important in middle-income nations which have already established a basic EMS.     

Serum sialic acid and its relationship to various haematological parameters, including erythrocyte sedimentation rate

Policies regarding ambulance diversion are critical to ensuring that EMS providers are aware of appropriate patient destinations, even before patients enter the system. Field EMS personnel should never be requested to prolong transport time intervals to search for an available hospital at the potential expense of patients' conditions and the immediate availability of out-of-hospital emergency care for the community. The responsibility for providing efficient emergency care to the community rests with all those who contribute to EMS structures and processes. All EMS system participants, including hospitals, EMS providers, local and regional lead agencies, and medical oversight authorities, must work together to create comprehensive ambulance diversion policies that satisfactorily meet each other's needs, while maintaining the highest regard for the needs of EMS patients and the entire community.     

Physical diagnosis skills of physicians in training: a focused assessment

OBJECTIVE: To assess the proficiency of emergency medicine (EM) trainees in the recognition of physical findings pertinent to the care of the critically ill patient. METHODS: Fourteen medical students, 63 internal medicine (IM) residents, and 47 EM residents from three university-affiliated programs in Philadelphia were tested. Proficiency in physical diagnosis was assessed by a multimedia questionnaire targeting findings useful in emergencies or related to diseases frequently encountered in the ED. Attitudes toward diagnosis not based on technology, teaching practices of physical examination during EM training, and self-motivated learning of physical diagnosis also were assessed for all the EM trainees. RESULTS: With the exception of ophthalmology, the EM trainees were never significantly better than the senior students or the IM residents. They were less proficient than the IM residents in cardiology, and not significantly different from the IM residents in all other areas. For no organ system tested, however, did they achieve less than a 42.9% error rate (range: 42.9-72.3%, median = 54.8%). There was no significant improvement in proficiency over the three years of customary EM training. The EM residents who had received supervised teaching in physical diagnosis during training achieved a significantly higher cumulative score. The EM residents attributed great clinical importance to physical diagnosis and wished for more time devoted to its teaching. CONCLUSIONS: These data confirm the recently reported deficiencies of physical diagnosis skills among physicians in training. The results are particularly disturbing because they relate to EM trainees and concern skills useful in the ED. Physical diagnosis should gain more attention in both medical schools and residency programs.     

Opposing national stroke mortality trends in Poland and for African Americans and whites in the United States, 1968 to 1994

BACKGROUND AND PURPOSE: The United States (US) has experienced declines in stroke mortality in contrast to the increases reported for Poland. As part of the Poland and US Agreement on Cardiovascular and Cardiopulmonary Research, stroke mortality trends in Polish and US subpopulations were compared in the context of cross-population differences in competing causes of death and determinants of stroke. METHODS: Age-adjusted annual stroke, cardiovascular disease (CVD), non-CVD, and all-cause mortality rates were determined for men and women aged 35 to 64 and 65 to 74 years from 1968 to 1994 for African Americans and US whites and in Poland. Mean annual percent changes of mortality rates were estimated during 1968 to 1980 and 1981 to 1994 with the use of piecewise log-linear regression. RESULTS: US stroke mortality rates declined 3.7% to 4.8% annually during 1968 to 1980 and 2.0% to 3.1% during 1981 to 1994, with similar declines in each ethnic, gender, and age group. Polish rates increased 3.3% to 5.5% annually for all age-gender groups in Poland during 1968 to 1980. Polish men aged 35 to 64 experienced increasing rates during 1981 to 1994 (1.6% annually), while Polish women and older men experienced slight declines or little change. Only Polish men aged 35 to 64 years exhibited increases in stroke, CVD, and non-CVD mortality rates during both time intervals. CONCLUSIONS: Poland and the US experienced opposing stroke mortality rate trends between 1968 and 1994. These national and ethnic trends occurring in just one generation suggest major effects of lifestyle, socioenvironmental, and/or medical care determinants.     

Oral rehydration therapy

Acute gastroenteritis is a leading cause of visits to physicians among children in the United States. Oral rehydration therapy has prevented or reversed dehydration among millions of children in developing countries. Although most U.S. health care providers are familiar with oral rehydration therapy, its proper use is still not widespread in industrialized nations. Viral pathogens in diarrheal illness can destroy absorptive cells at the intestinal villous tip while leaving secretory cells intact. Oral rehydration therapy takes advantage of the remaining intact absorptive cells, is less invasive than intravenous rehydration and allows parents to be involved in their children's care. This article outlines how to select patients for oral rehydration therapy, what fluids to use and how to implement therapy.     

The case of myoepithelioma of the parotid gland

STUDY OBJECTIVE: To determine whether the environment of a moving ambulance affects the ability of our-of-hospital care providers to auscultate breath sounds. METHODS: Out-of-hospital care providers assessed breath sounds with a previously described breath-sounds model in a quiet environment (control) and in a moving ambulance. The setting was a nonurban emergency medical services system and an interhospital transport agency based at a 600-plus-bed tertiary care center. The participants were physicians, transport nurses, and advanced life support EMS providers routinely involved in the emergency out-of-hospital treatment and transportation of the ill and injured. The accuracy with which participants identified the presence or absence of breath sounds in the two environments was compared with the use of the chi 2 test, with the alpha-value set at .05. RESULTS: The accuracy of breath-sounds assessment in the control environment was 96% (251 of 260); the sensitivity was 96% and the specificity 97%. The accuracy of breath-sounds assessment in the experimental environment was 54% (140 of 260); the sensitivity was .09% and the specificity 98%. Participants were significantly less likely to hear breath sounds in the moving ambulance than in the quiet room (P < .001). CONCLUSION: Assessment of breath sounds is hampered by the environment of a moving ambulance.     

Reperfusion injury delays healing of intestinal anastomosis in a rat

This SAEM position paper clarifies the role of emergency medicine in health care delivery. It builds upon the working definition of emergency medicine developed by the American College of Emergency Physicians in 1994 by describing the health care role of emergency physicians (EPs). EPs are first-contact providers who care for all patients regardless of age, gender, time of presentation, or ability to pay. They remain the only continuously accessible specialty for patients seeking help and solace in the health care system. They are an essential link in the health care continuum between primary care physicians, specialists, the out-of-hospital system, the patient, inpatient services, and communication services. The EP's role is in organizing and monitoring the emergency care delivery system. Part of this role is to better align the health care provider training and ability with the specific medical needs of a patient. The emergency health care system remains the essential medical safety net for all individuals needing care in this country.     

Physician migration to the U.S.--foreign aid for U.S. manpower

Data were obtained from the American Medical Association on Iranian physicians practicing in the U.S., and from the Iranian Medical Registry on U.S.-trained Iranian physicians who have returned to practice in Iran. There were 2,066 Iranian physicians practicing in the U.S. in 1972, 1,234 (60%) of whom were not undergoing any training. Only 600 of Iran's 9,535 physicians in 1972 had been trained in the United States. Thus, less than one-third of the specialists who have completed training in the U.S. have returned to practice in Iran. The specialist group with the highest rate of return is the combined surgery subspecialties (neurosurgery, thoracic surgery, orthopedic surgery, and plastic surgery). The specialist groups with the lowest rates of return were pathology, anesthesiology, and psychiatry. A comparison is made of the manpower problems Iran faces and the American problems in the area of physician manpower.     

Work-related stress and depression among practicing emergency physicians: an international study

STUDY OBJECTIVE: To compare the levels of work-related stress and depression reported by practicing emergency physicians in three survey sites and to determine the effects of gender and marital status on the stress and depression experienced by these physicians. DESIGN: Cross-sectional mail surveys. SETTING AND PARTICIPANTS: Seven hundred sixty-four practicing emergency physicians from the United States, 91 fellows in full-time practice from Australasia, and 154 consultants and 47 senior registrars from the United Kingdom. INTERVENTION: Administration of questionnaires requesting demographic information and including an inventory to assess work-related stress and a scale to measure depressive symptomatology. MEASUREMENTS AND MAIN RESULTS: A 3 x 2 x 2 multivariate analysis of variance performed to compare scores on the stress inventory and depression scale simultaneously by survey site, gender, and marital status revealed significant differences in stress and depression by survey site and marital status. Univariate analyses of variance revealed significant differences in both stress and depression among the three survey sites and in depression by marital status. Adjusted means indicated that physicians from the United Kingdom reported higher levels of stress and depression than physicians from the United States and Australasia. Physicians from the United States and Australasia did not differ with respect to stress or depression. Physicians who were not married reported higher levels of depression than married physicians. No large mean differences, actual or adjusted, were found for any of the grouping factors. CONCLUSION: Statistical differences among practicing emergency physicians from the United States, Australasia, and the United Kingdom were observed, but the actual levels of work-related stress and depression were similar and did not appear severe. Marriage was associated with lower levels of depressive symptomatology.     

Incorporating a community-oriented approach in primary care

The health care system in the United States depends on primary care services. Yet the limitations imposed by traditional approaches in primary care have resulted in an unrealized potential for primary care. Currently, we rely on the motivation and initiative of persons to acquire the health care services they need, and health care providers have attempted to meet these needs. Community-oriented primary care provides an opportunity for primary care physicians to expand their range of services and their ability to reach out to people. Incorporating community-oriented primary care into primary health care has the potential to make a major contribution in reshaping health care in the United States.     

Managing dental care versus managed dental care: looking south from north of the 49th parallel

In the United States, aggregate expenditures on the largely private health care system, as a proportion of Gross National Product, exceed those of all other countries. Under private enterprise, the health care system in the United States grew as predicted by the underlying equation that more service volume equates to more revenue for hospitals and providers. Managed care is the response of for-profit health care organizations to meet the demands of U.S. corporations to contain the escalating costs of hospital, medical and other health care benefits for their employees. Managed health care has several models, but preferred provider organizations (PPOs) have been the model that has increased most rapidly. In contrast, managers of Canadian public dental programs plan, organize, direct and control more of the structures, processes and outputs to achieve desired outcomes for special groups. In Canada, the approaches to quality assurance, restraint of trade and the power of the professional lobby are different from the approaches in the United States. Nonetheless, the context of private dental care plans is very similar to the context that produced managed health care in the United States. Better management to meet demonstrated needs with evidence-based care can result in sustainable, adequately financed plans and avoid the deep-discount form of managed dental care.     

Quality of life following spinal cord injury: knowledge and attitudes of emergency care providers

STUDY OBJECTIVES: To measure emergency care providers' attitudes toward quality of life after spinal cord injury (SCI) and to determine if their perceptions influence the care they provide. DESIGN: A closed-ended questionnaire. SETTING AND PARTICIPANTS: Two hundred thirty-three emergency nurses, emergency medicine technicians, emergency medicine residents, and attending physicians at three level I trauma centers were surveyed. Their responses were compared with previously reported quality-of-life ratings of a group of 128 high-level SCI survivors. MEASUREMENTS AND RESULTS: One hundred fifty-three emergency care providers completed the survey (response rate, 63%). Forty-one percent believed that resuscitation efforts after severe SCI are too aggressive, and 28% believed that future quality of life should be a factor in determining the interventions that should be provided. If they sustained severe SCIs themselves, 22% of providers would want nothing done to ensure their survival, and 23% would want pain relief only. Only 18% imagined they would be glad to be alive with a severe SCI, compared with 92% of a true SCI comparison group. Seventeen percent of providers anticipated an average or better quality of life compared with 86% of the actual SCI comparison group. CONCLUSION: The quality of life, self-esteem, and outcomes that emergency health care providers imaging after SCI are considerably more negative than those reported by SCI survivors. Because providers' knowledge and attitudes may affect the care they provide and may influence patients and families struggling with critical treatment decisions, emergency care providers must be aware of outcomes, well-being, and life satisfaction following severe SCI.
