Continuing Medical Education in Midpassage

Mandatory continuing education for physicians and other health professionals raises numerous problems. Issues that were considered academic when continuing education was voluntary now take on major practical and political significance. There is the risk that future legislation will mandate activities and methodologies which have not been proven. Research and development in continuing education must be accelerated so that decisions can be based on proper data. Centers of research and development should be established to encourage research and provide a sound foundation for the future of continuing education.     

Preventive attitudes,beliefs, and practices of physicians in fee-for-service and health maintenance organization settings.

To identify the self-reported differences in preventive practices, attitudes, and beliefs of physicians practicing in fee-for-service (FFS) and health maintenance organization (HMO) settings, we surveyed a 100% sample of primary care physicians practicing in a large, urban, closed-panel HMO and a random sample of physicians, in the same county, who were in an FFS practice. The FFS physicians were more likely to consider behavioral risk factors important than were HMO physicians, and they were more likely to ask their patients about behavioral risk factors. Fee-for-service physicians were more likely than HMO physicians to use continuing medical education courses to upgrade their skills in modifying behavioral risk factors. There was little difference in the self-reported proportion of patients with specific behavioral risks in the FFS and HMO practices. Also, both groups were comparable in their perception of their ability to do behavioral counseling and their perceived success in such counseling. We conclude that FFS physicians are more likely to have positive preventive beliefs, attitudes, and practices than are HMO physicians.     

The new face of health care in Ontario

Canada is experiencing a dramatic increase in the number of older people in its population. Adopting strategies that involve physician actions, a societal approach and individual participation may substantially improve the health of senior citizens. This article presents ways to improve the quality of life and reduce the risk of premature death through manoeuvres that can be initiated by physicians in the context of the periodic health examination. The authors highlight the role of evidence in choosing the most appropriate interventions, speculate on areas of future importance and emphasize a societal approach to population health.     

Awareness of Stroke Risk after TIA in Swiss General Practitioners and Hospital Physicians

Background

Transient ischemic attacks (TIA) are stroke warning signs and emergency situations, and, if immediately investigated, doctors can intervene to prevent strokes. Nevertheless, many patients delay going to the doctor, and doctors might delay urgently needed investigations and preventative treatments. We set out to determine how much general practitioners (GPs) and hospital physicians (HPs) knew about stroke risk after TIA, and to measure their referral rates.

Methods

We used a structured questionnaire to ask GPs and HPs in the catchment area of the University Hospital of Bern to estimate a patient’s risk of stroke after TIA. We also assessed their referral behavior. We then statistically analysed their reasons for deciding not to immediately refer patients.

Results

Of the 1545 physicians, 40% (614) returned the survey. Of these, 75% (457) overestimated stroke risk within 24 hours, and 40% (245) overestimated risk within 3 months after TIA. Only 9% (53) underestimated stroke risk within 24 hours and 26% (158) underestimated risk within 3 months; 78% (473) of physicians overestimated the amount that carotid endarterectomy reduces stroke risk; 93% (543) would rigorously investigate the cause of a TIA, but only 38% (229) would refer TIA patients for urgent investigations “very often”. Physicians most commonly gave these reasons for not making emergency referrals: patient’s advanced age; patient’s preference; patient was multimorbid; and, patient needed long-term care.

Conclusions

Although physicians overestimate stroke risk after TIA, their rate of emergency referral is modest, mainly because they tend not to refer multimorbid and elderly patients at the appropriate rate. Since old and frail patients benefit from urgent investigations and treatment after TIA as much as younger patients, future educational campaigns should focus on the importance of emergency evaluations for all TIA patients.     

Early detection and treatment of hyperlipidemia: physician practices in Canada.

We surveyed primary care physicians in Canada to determine their current practices regarding the detection and treatment of hyperlipidemia in asymptomatic adults 20 years of age or more and to determine the role of selected patient characteristics (age, sex and the presence of coronary heart disease [CHD] risk factors) in their management decisions. The self-administered questionnaire was completed by 428 of 804 family physicians and general practitioners. The proportion of physicians who reported having tested at least 50% of their adult patients varied from 29% to 85% and was related to the number of CHD risk factors present and the patient''s age. The proportion of respondents who reported starting dietary or drug therapy among patients with a cholesterol level of 6.2 mmol/L or less increased as the number of CHD risk factors increased and was not related to patient age or sex. According to the factors examined our results suggest that primary care physicians in Canada select patients for screening and treatment mainly on the basis of CHD risk factors present and that their approach is more conservative than that recommended by the Canadian and US consensus conferences.     

Risk factors for cardiovascular diseases in physicians

The aim of the study was to determine the prevalence of risk factors for cardiovascular diseases among physicians at a teaching hospital. In total, 203 men and 167 women were included in the study. The participants filled in a questionnaire; their height, weight, blood pressure, serum cholesterol and glucose levels were added. 19.2 % males and 13.8 % females were smokers, hypertension was diagnosed in 10 % of males and in 6.6 % of females, 52.2 % males and 17.4 % females were overweight, 37 % males and 43.1 % females had hypercholesterolemia. The above findings suggest that Czech physicians have more favourable values of all the studied cardiovascular diseases risk factors than the general Czech population. However, Czech physicians smoke more than those in other countries and their level of cardiovascular diseases risk factors is unsatisfactory and calls for further intensive prevention. Preliminary outcomes of the study repeated after two years show no positive trends as well as physicians' low willingness to actively participate in lowering cardiovascular diseases risk factors.     

The perception of teratogenic risk of cocaine.

While there has been a substantial increase in recreational use of cocaine by young adults, conclusive evidence for cocaine teratogenicity in humans is lacking, and even those believing the drug is teratogenic agree that the rates are quite small. While counseling pregnant women on their teratogenic risk, it was our impression that there is an unrealistically high perception of reproductive risk of cocaine. We wished to quantify the perception of teratogenic risk of cocaine by the public, physicians, and by pregnant women who were counseled following gestational exposure to the drug. Women taking cocaine during the first trimester of pregnancy (n = 54), controls with post secondary education (n = 30), and physicians (n = 30) were asked, using a visual analogue scale, to quantify the teratogenic risk of cocaine and the tendency to terminate/continue the pregnancy after first trimester exposure; in the case of the "public" and physicians this was a hypothetical question. Both physicians and the controls perceived cocaine to be teratogenic (13.4 +/- 11% risk of major malformations by physicians, and 56.5 +/- 22.8% by the "public"). The controls believed cocaine to be as hazardous as thalidomide (57.2 +/- 25.6% risk for thalidomide). Asked whether they would wish to terminate such pregnancy in their family, most physicians (56%) and the controls (70%) had a greater than 50% tendency to terminate.(ABSTRACT TRUNCATED AT 250 WORDS)     

RADIATION: MEDICAL DIAGNOSTIC USES

Use of radiologic procedures in diagnosis now contributes a significant dose of ionizing radiation to our population. Whether this presents a real risk to the health of the present and future population cannot be determined with certainty from evidence available at this time. Hence, it appears proper to keep the dose to every patient as low as practical consistent with good medical practice. The average dose can be significantly reduced by having more physicians apply the known techniques for minimizing the exposure to the patient.The medical profession has a direct professional concern for the actual or potential risk of damage resulting from the radiation that patients are exposed to during diagnostic x-ray procedures, since these procedures constitute the largest single man-made source of genetically significant radiation our population is now exposed to.It is important to distinguish two distinctly different types of radiation effects—somatic effect, in which the damage affects the health of the person irradiated, and genetic effect that is capable of producing constitutional defects in future progeny over many generations.     

Pheo or not a pheo,that is the question.

The current fault-based tort system assumes that claims made against physicians are inversely related to the quality of care they provide. In this study we identified physician characteristics associated with elements of medical care that make physicians vulnerable to malpractice claims. A sample of physicians (n = 248) thought to be at high or low risk for claims was surveyed on various personal and professional characteristics. Statistical analysis showed that 9 characteristics predicted risk group. High risk was associated with increased age, surgical specialty, emergency department coverage, increased days away from practice, and the feeling that the litigation climate was "unfair." Low risk was associated with scheduling enough time to talk with patients, answering patients'' telephone calls directly, feeling "satisfied" with practice arrangements, and acknowledging greater emotional distress. Prediction was more accurate for physicians in practice 15 years or less. We conclude that a relationship exists between a history of malpractice claims and selected physician characteristics.     

The Role of the Practising Physician in Medical Student Recruitment

The role that the practitioner of medicine can play in assisting recruitment to medical schools is examined. Although the total enrolment in universities has increased sharply in the past decade, the group applying to enter medicine has decreased. The output of Canada''s 12 schools of medicine—850 graduates per year-falls significantly short of the number of new physicians required to maintain the present physician:population ratio. With the expanded output of physicians required in future, an active program of recruitment will be necessary. The recruitment program organized by the practising physicians of British Columbia and the Faculty of Medicine at the University of British Columbia is outlined.     

Relation of family physician or specialist care to obstetric interventions and outcomes in patients at low risk: a western Canadian cohort study.

To determine the relation of family physician or specialist care to intrapartum interventions and outcomes, we carried out a historical cohort study of 1456 obstetric patients at low risk admitted between Nov. 15, 1984, and Mar. 15, 1986, to a western Canadian teaching hospital. The patients were classified as being at low risk on admission by means of chart review. Family physicians and specialists were found to have similar rates for most of the interventions measured, although the interventions for which significantly different rates were found suggest a less interventionist style of intrapartum care by family physicians. There were no significant differences in maternal or neonatal outcomes except for a higher proportion of infants weighing less than 2500 g among primigravid women cared for by family physicians compared with those under the care of specialists. Self-selection of physician specialty by patients resulted in differences in the demographic characteristics of the two patient populations. The findings support the continued involvement of family physicians in the provision of obstetric care.     

Attitudes about Tuberculosis Prevention in the Elimination Phase: A Survey among Physicians in Germany

Background

Targeted and stringent measures of tuberculosis prevention are necessary to achieve the goal of tuberculosis elimination in countries of low tuberculosis incidence.

Methods

We ascertained the knowledge about tuberculosis risk factors and stringency of tuberculosis prevention measures by a standardized questionnaire among physicians in Germany involved in the care of individuals from classical risk groups for tuberculosis.

Results

510 physicians responded to the online survey. Among 16 risk factors immunosuppressive therapy, HIV-infection and treatment with TNF-antagonist were thought to be the most important risk factors for the development of tuberculosis in Germany. Exposure to a patient with tuberculosis ranked on the 10^th position. In the event of a positive tuberculin-skin-test or interferon-γ release assay only 50%, 40%, 36% and 25% of physicians found that preventive chemotherapy was indicated for individuals undergoing tumor necrosis factor-antagonist therapy, close contacts of tuberculosis patients, HIV-infected individuals and migrants, respectively.

Conclusions

A remarkably low proportion of individuals with latent infection with Mycobacterium tuberculosis belonging to classical risk groups for tuberculosis are considered candidates for preventive chemotherapy in Germany. Better knowledge about the risk for tuberculosis in different groups and more stringent and targeted preventive interventions will probably be necessary to achieve tuberculosis elimination in Germany.     

THE NUMBER AND DISTRIBUTION OF PHYSICIANS IN CALIFORNIA

The ratio of physicians to general population in California has been approximately the same for many years, the influx of physicians having kept pace with the population trend.For many years California has licensed more physicians than any other state.The five medical schools in this state have been increasing the number of candidates admitted to the freshman class. Attempts are being made to increase the number of medical schools in this state to seven in anticipation of the future growth and medical needs of the population.The heaviest concentration of physicians is as always in the thickly populated areas as determined by the population physician ratio.A study of the detailed statistics presented in this paper should be of interest to all California physicians.     

Forecasting Japan's Physician Shortage in 2035 as the First Full-Fledged Aged Society

Introduction

Japan is rapidly becoming a full-fledged aged society, and physician shortage is a significant concern. The Japanese government has increased the number of medical school enrollments since 2008, but some researchers warn that this increase could lead to physician surplus in the future. It is unknown how many physicians will be required to accommodate future healthcare needs.

Materials and Methods

We simulated changes in age/sex composition of the population, fatalities (the number of fatalities for the consecutive five years), and number of physicians from 2010 to 2035. Two indicators were defined: fatalities per physician and fatalities by physician working hour, based on the data of the working hours of physicians for each tuple of sex and age groups. We estimated the necessary number of physicians in 2035 and the number of new physicians to maintain the indicator levels in 2010.

Results

The number of physicians per 1,000 population is predicted to rise from 2·00 in 2010 to 3·14 in 2035. The number of physicians aged 60 years or older is expected to increase from 55,375 (20% of physicians) to 141,711 (36%). In 2010 and 2035, fatalities per physician were 23·1 and 24·0 for the total population, and 13·9 and 19·2 for 75 years or older, respectively. Fatalities per physician working hour are predicted to rise from 0·128 to 0·138. If working hours are limited to 48 hours per week in 2035, the number of fatalities per physician working hour is expected to be 0·196, and the number of new physicians must be increased by 53% over the current pace.

Discussion

The number of physicians per population continues to rise, but the estimated supply will not fulfill the demand for healthcare in the aging society. Strategies to increase the number of physicians and improve working conditions are urgently needed.     

Frequency of discussing HIV prevention and care topics with patients with HIV: Influence of physician gender,race/ethnicity,and practice characteristics

Background: Because people living with HIV now have greater life expectancy and reduced morbidity, there is a greater need for physicians to discuss HIV transmission risk reduction with these patients. Very limited data are available examining how frequently this discussion is held.Objective: We examined the frequency of discussing HIV prevention and HIV care topics, as well as the associations of gender, race/ethnicity, and practice characteristics of physicians caring for persons with HIV.Methods: In a 4-city (Miami, Atlanta, Baltimore, Los Angeles) survey, 417 licensed physicians who primarily cared for patients with HIV were mailed a 58-item questionnaire about how frequently they discussed HIV transmission risk reduction, adherence to HIV antiretroviral treatment (ART), adherence to opportunistic infection (OI) prophylaxis, and how to take medicines. Multivariate logistic regression analyses were used to examine the association between physician gender, race/ethnicity, and practice characteristics, and the frequency of discussing these topics.Results: A total of 317 physicians responded to the mailed questionnaire. Less than 40% of the physicians reported always discussing HIV transmission risk reduction with patients. In contrast, 83.9% and 65.0% reported always discussing adherence to ART and to OI prophylaxis, respectively. Of these physicians, 65.1% strongly agreed or somewhat agreed that they had sufficient time to provide the care and information needed to their patients. In multivariate analysis, the frequency of discussing HIV transmission risk reduction was higher for physicians who were Hispanic (P = 0.03) or Asian/Pacific Islander (P = 0.001), for physicians who reported they had enough time to provide care and information to patients (P = 0.003), and for physicians who cared for fewer patients (P = 0.05). The frequency of discussing HIV transmission risk reduction was suggestive of a higher rate for female physicians, but did not quite reach statistical significance.Conclusions: We observed a lower frequency of discussing the topic of HIV prevention compared with that of HIV care among the physicians surveyed. This infrequent discussion with patients with HIV represents a missed opportunity, and physicians should be encouraged to include discussion of prevention as a standard of care.     

Patterns of practice among older physicians in Ontario

BACKGROUND: Policy-makers interested in the supply of doctors in Canada have recently begun focusing attention on older physicians. This study informs the policy debate by analysing the practice patterns of Ontario physicians aged 65 years and over. METHODS: A cross-sectional and longitudinal analysis of physician claims data for fiscal years 1989/90 through 1995/96 was conducted. The number of full-time equivalent (FTE) physicians by age category, urban or rural status, and specialty was calculated by means of an established method, and differences between older physicians, established physicians and recent graduates (in practice for 5 years or less), in terms of the types of services provided and patients seen, were examined. RESULTS: The proportion of FTE physicians aged 65 or more increased from 5.3% to 7.0% during the study period, whereas the proportion of recent graduates decreased from 19.6% to 16.3%. Of the older physicians, 61.4% practised part time (less than 1 FTE). Half of the physicians aged 75 in 1989/90 were still in practice 6 years later. Older physicians were less likely than those under age 65 to practice obstetrics (4.6% v. 16.9%), provide emergency department services (1.1% v. 14.8%) or house calls (38.7% v. 60.4%), or perform many minor procedures (38.7% v. 62.3%) (p < or = 0.001 for all comparisons). Older physicians tended to be male and had older patients in their practices than did younger physicians. Rural regions had higher proportions of older specialists. INTERPRETATION: Ontario''s physician corps is aging. This may result in decreasing availability of obstetrics and emergency department coverage in the future. Encouraging retirement may create more openings for recent graduates, but if such policies are enacted, special attention should be paid to ensure that rural communities and older patients continue to be served.     

Historical review of occupational exposures and cancer risks in medical radiation workers

Epidemiological studies of medical radiation workers have found excess risks of leukemia, skin and female breast cancer in those employed before 1950 but little consistent evidence of cancer risk increases subsequently. Occupational radiation-related dose-response data and recent and lifetime cancer risk data are limited for radiologists and radiologic technologists and lacking for physicians and technologists performing fluoroscopically guided procedures. Survey data demonstrate that occupational doses to radiologists and radiologic technologists have declined over time. Eighty mostly small studies of cardiologists and fewer studies of other physicians reveal that effective doses to physicians per interventional procedure vary by more than an order of magnitude. For medical radiation workers, there is an urgent need to expand the limited information on average annual, time-trend and organ doses from occupational radiation exposures and to assess lifetime cancer risks of these workers. For physicians and technologists performing interventional procedures, more information about occupational doses should be collected and long-term follow-up studies of cancer and other serious disease risks should be initiated. Such studies will help optimize standardized protocols for radiologic procedures, determine whether current radiation protection measures for medical radiation workers are adequate, provide guidance on cancer screening needs, and yield valuable insights on cancer risks associated with chronic radiation exposure.     

Peptic Ulcer Disease in Healthcare Workers: A Nationwide Population-Based Cohort Study

Health care workers (HCWs) in Taiwan have heavy, stressful workloads, are on-call, and have rotating nightshifts, all of which might contribute to peptic ulcer disease (PUD). We wanted to evaluate the PUD risk in HCWs, which is not clear. Using Taiwan’s National Health Insurance Research Database, we identified 50,226 physicians, 122,357 nurses, 20,677 pharmacists, and 25,059 other HCWs (dieticians, technicians, rehabilitation therapists, and social workers) as the study cohort, and randomly selected an identical number of non-HCW patients (i.e., general population) as the comparison cohort. Conditional logistical regression analysis was used to compare the PUD risk between them. Subgroup analysis for physician specialties was also done. Nurses and other HCWs had a significantly higher PUD risk than did the general population (odds ratio [OR]: 1.477; 95% confidence interval [CI]: 1.433–1.521 and OR: 1.328; 95% CI: 1.245–1.418, respectively); pharmacists had a lower risk (OR: 0.884; 95% CI: 0.828–0.945); physicians had a nonsignificantly different risk (OR: 1.029; 95% CI: 0.987–1.072). In the physician specialty subgroup analysis, internal medicine, surgery, Ob/Gyn, and family medicine specialists had a higher PUD risk than other physicians (OR: 1.579; 95% CI: 1.441–1.731, OR: 1.734; 95% CI: 1.565–1.922, OR: 1.336; 95% CI: 1.151–1.550, and OR: 1.615; 95% CI: 1.425–1.831, respectively). In contrast, emergency physicians had a lower risk (OR: 0.544; 95% CI: 0.359–0.822). Heavy workloads, long working hours, workplace stress, rotating nightshifts, and coping skills may explain our epidemiological findings of higher risks for PUD in some HCWs, which might help us improve our health policies for HCWs.     

Chickenpox in Canada, 1924-87.

Because of the lack of an effective vaccine and the difficulty in implementing any effective control measures, physicians and public health practitioners have paid little attention to understanding the epidemiologic features of chickenpox. No data on the incidence rate in Canada are available for 1959-85. However, Ontario data suggest an overall decrease in the annual rate during the 1960s and a stable rate since the mid-1970s. High incidence rates are expected among children 5 to 9 years of age because of their susceptibility and their greater exposure in school. Low incidence rates among older age groups are expected, because most of these people have already been exposed to the virus. The disease is more serious among infants than among other children. The risk of death from chickenpox is also highest among infants. More patient-specific information and improved collection of incidence data are required to measure any impact from future control procedures, including the use of vaccines currently being developed.
