Manpower needs in academic emergency medicine.

One of the value statements of the American College of Emergency Physicians states that, "Quality Emergency Medicine is best practiced by qualified, credentialed emergency physicians." To address this value ACEP has established the following goal: "The number of board-certified physicians will be sufficient to meet the manpower needs of the public." It is the position of ACEP that there is currently a severe shortage of appropriately trained and certified emergency physicians and, moreover, that the shortage will continue well into the next century. We discuss how ACEP arrived at this position and the role of academic emergency medicine in addressing this shortage. For many years, there has been a public debate as to whether there is a physician shortage or surplus. The Graduate Medical Education National Advisory Commission report of 1980 estimated that there would be 630,000 US physicians by 1990, with a surplus of 70,000. This report also identified emergency medicine as a shortage specialty, indicating there would be a need for 14,000 emergency physicians in 1990, with a supply of only 8,000. Schwartz included such factors as increased provision of administrative and research activity by physicians and concluded that there would be a shortage of 7,000 physicians by the year 2,000.

An ethics curriculum for teaching emergency medicine residents.

Instruction in medical ethics has become standard in undergraduate medical education within the past decade; more recently, several specialty boards have formally endorsed ethics teaching and evaluation for residents as well. However, the current emergency medicine Core Content, representing emergency medicine's central body of knowledge, makes no specific mention of ethics. An ethics curriculum is proposed to remedy this gap in the emergency medicine residency curriculum. Issues frequently encountered in the emergency department are emphasized, and topics include moral foundations of clinical medicine, the unique ethical concerns of emergency medicine, patient competence, informed consent and refusal of treatment, truthfulness, confidentiality, foregoing life-sustaining treatment, duty to provide care, moral issues in disaster medicine, allocation of health care, and research and teaching involving human subjects. Educational objectives and readings for each of these topics are presented along with sample case scenarios to be used in a small group discussion format.

Fetal liver length in normal and isoimmunized pregnancies.

The length of the right lobe of the fetal liver was measured by means of ultrasound examined on 53 occasions in 21 isoimmunized pregnancies. Fetal blood samples were taken in all patients within 24 hours. Comparisons were made with 350 measurements of liver length in normal pregnancies. A good correlation was found between liver length and fetal hemoglobin level (r = 0.794, p less than 0.001) and between liver length and reticulocyte count (r = 0.721, p less than 0.001). At the time of first sample, all fetuses with a hemoglobin of less than 100 gm/L had a liver length that was greater than the ninetieth percentile. Liver length measurement seems to be a useful indicator of the degree of fetal anemia in isoimmunized pregnancies.

Substantial work disability and earnings losses in individuals less than age 65 with osteoarthritis: comparisons with rheumatoid arthritis.

Substantial earnings losses and work disability were seen in individuals less than age 65 with asymmetric oligoarthritis, a surrogate for osteoarthritis, almost as great as those seen with symmetric polyarthritis, a surrogate for rheumatoid arthritis. The proportions of individuals who were working was 66.7% for men and 35.5% for women with asymmetric oligoarthritis, compared to 56.1% and 31.0% of those with symmetric polyarthritis, and 89.4 and 61.6% of those with no arthritis. Rates of work disability in individuals with asymmetric oligoarthritis involving one knee or one hip were in the same range as those in individuals with symmetric polyarthritis involving two knees or two hips. The earnings of women and men with asymmetric oligoarthritis were only 30 and 63% respectively of the earnings of persons with no arthritis. However, less than one-third of these earnings losses were explained by the presence of arthritis, with further explanation from higher age, lower formal education levels, and comorbidity in individuals with asymmetric oligoarthritis. These results suggest that greater attention to demographic and comorbidity variables may be indicated in efforts to control economic losses associated with arthritis.

Mental health and the labor force participation of older workers.

Over the past 20 years, while mortality rates have dramatically declined, the prevalence of work-related stress has increased. This phenomenon suggests that the population's physical health has improved, but mental health has deteriorated. Concomitantly, fewer older workers are participating in the labor force. Our paper, using data from the Epidemiologic Catchment Area (ECA) program, assesses whether the decline in numbers of older workers is linked to the increasing prevalence of job-related stress. Our results indicate that symptoms of poor mental health are the most important determinants of work behavior. Surprisingly, economic and demographic characteristics appear to have little impact on an individual's labor force participation status. Further research is needed, however, because the ECA data provides insufficient information to accurately assess the relative importance of both mental health and economic factors on the retirement decision.

Thyroid disease in the emergency department. Thyroid function tests and hypothyroidism and myxedema coma.

The recognition of hypothyroidism may not always be easy in the emergency department setting. Laboratory evaluations of thyroid function are not usually performed on a 24-hour basis, and therefore the emergency physician, although suspecting the presence of hypothyroidism, may be unable to confirm the diagnosis while the patient is in the Emergency Department. It is not always the responsibility of the emergency physician to diagnose hypothyroidism, but in some clinical settings it may be important to include thyroid function tests in laboratory evaluation of patients to ensure adequate patient care and followup. Careful attention to nonspecific complaints, myxedematous changes, and signs of dysfunction of any organ system, especially in older female patients, may lead to the ultimate correct diagnosis. Myxedema coma is potentially fatal and must be recognized and treated emergently, usually prior to laboratory confirmation. Ventilatory support and thyroid hormone replacement are the two most important therapeutic maneuvers in the treatment of myxedema coma.

The importance of age, education, and comorbidity in the substantial earnings losses of individuals with symmetric polyarthritis.

A population-based survey designed to be representative of the entire US population of working age (18-64 years) includes data on pain and swelling of specific joints in each subject. We analyzed these data to estimate work status and disability status, as well as earnings losses, associated with Symmetric Polyarthritis. Subjects identified in the survey as having Symmetric Polyarthritis were similar in age, race, sex, and marital status to rheumatoid arthritis patients seen in clinical settings. Overall, 51% of women with Symmetric Polyarthritis and 47% of men with Symmetric Polyarthritis were severely disabled, compared with 4.5% of women and 3.7% of men with no arthritis. Earnings of women and men with Symmetric Polyarthritis were only 27% and 48%, respectively, of earnings of individuals without arthritis. The total earnings gap between the 2 groups was +17.6 billion (1986 dollars). Econometric regression analyses indicated that about one-third of this earnings gap was explained by the presence of Symmetric Polyarthritis. The remaining two-thirds was explained by differences in age, education, and comorbidity between individuals with Symmetric Polyarthritis and those without arthritis. The earnings of individuals with Symmetric Polyarthritis, therefore, would be expected to be considerably lower than those of the general population, even if these individuals were not affected by arthritis. Nonetheless, earnings losses of at least +6.5 billion annually are explained by Symmetric Polyarthritis.

Arthritis and the earnings of men. An analysis incorporating selection bias.

Arthritis is a chronic and crippling disease which affects the work effort and earnings of more than 14 million working-age victims. This paper examines the effects of arthritis on the earnings of men aged 18 to 64. Arthritis has large and significant effects on earnings. Most models incorporating selection bias have examined groups with lower labor force participation rates than prime-age males, but significant selection bias is found here. When selection bias is considered, the estimated absolute effects of arthritis are increased and the percentage of the gap between arthritic and non arthritic males explained by arthritis, as opposed to other factors, increases. This study is unusual in identifying the effects of a single disease on earnings.

Cardiopulmonary arrest secondary to lightning injury in a pregnant woman.

A young woman who was seven months pregnant was struck by lightning, resulting in cardiopulmonary arrest. Bystander CPR was begun at the scene. Vital signs were restored by the time the rescue squad arrived. The patient was comatose on arrival in the emergency department and fetal death was apparent. The patient's neurological status improved markedly, with a small residual motor deficit.

Effects of arthritis on wage earnings.

Arthritis is the most frequently reported health condition in the working-age population, reported by nearly one quarter of the age 45 to 64 population in the 1978 Social Security Survey of disability and work. An economic model of earnings, which controls for differences in socioeconomic characteristics and other health conditions, indicates that arthritis is responsible for an annual loss of approximately $17 billion in wage earnings in the United States.

Pacemaker therapy in the seventies: interaction of patient age, time of implant, and indications for pacing.

In the 1970s, 707 patients received a primary pacemaker implant in our hospital. An analysis of the indications for pacemaker therapy revealed that one-third had third degree heart block, one-third had sick sinus syndrome and one-third had other indications. The distribution of indications was identical in all age groups. Furthermore, this distribution did not change from the first half of the decade to the second.
