Medical Education and Research: The Foundations of Quality Health Care

In May 1964 the Royal Commission on Health Services declared that “health research is essential to health progress”. However, since that time the means of providing adequate health care have received far less attention than have methods of payment for physicians'' services. Because medical education and research is the source from which all other health benefits flow, urgent attention must be paid to the adequate support of teacher-scientists, as set forth in the Woods, Gordon (Gundy) report. It is the numbers and quality of these men and women, more than any other factor, that will determine the shape of medical science and, hence, medical practice in Canada in the future. Expensive as it is, Canadian medicine and Canadian medical scientists must have generous support if medical care in this country is to be of high quality.     

Which physicians make home visits and why? A survey

BACKGROUND: Recent changes in the North American health care system and certain demographic factors have led to increases in home care services. Little information is available to identify the strategies that could facilitate this transformation in medical practice and ensure that such changes respond adequately to patients'' needs. As a first step, the authors attempted to identify the major factors influencing physicians'' home care practices in the Quebec City area. METHODS: A self-administered questionnaire was sent by mail to all 696 general practitioners working in the Quebec City area. The questionnaire was intended to gather information on physicians'' personal and professional characteristics, as well as their home care practice (practice volume, characteristics of both clients and home visits, and methods of patient assessment and follow-up). RESULTS: A total of 487 physicians (70.0%) responded to the questionnaire, 283 (58.1%) of whom reported making home visits. Of these, 119 (42.0%) made fewer than 5 home visits per week, and 88 (31.1%) dedicated 3 hours or less each week to this activity. Physicians in private practice made more home visits than their counterparts in family medicine units and CLSCs (centres locaux des services communautaires [community centres for social and health services]) (mean 11.5 v. 5.8 visits per week), although the 2 groups reported spending about the same amount of time on this type of work (mean 5.6 v. 5.0 hours per week). The proportion of visits to patients in residential facilities or other private residences was greater for private practitioners than for physicians from family medicine units and CLSCs (29.7% v. 18.9% of visits), as were the proportions of visits made at the patient''s request (28.0% v. 14.2% of visits) and resulting from an acute condition (21.4% v. 16.0% of visits). The proportion of physicians making home visits at the request of a CLSC was greater for those in family medicine units and CLSCs than for those in private practice (44.0% v. 11.3% of physicians), as was the proportion of physicians making home visits at the request of a colleague (18.0% v. 4.5%) or at the request of hospitals (30.0% v. 6.8%). Physicians in family medicine units and CLSCs did more follow-ups at a frequency of less than once per month than private practitioners (50.9% v. 37.1% of patients), and they treated a greater proportion of patients with cognitive disorders (17.2% v. 12.6% of patients) and palliative care needs (13.7% v. 8.6% of patients). Private practitioners made less use of CLSC resources to assess home patients or follow them. Male private practitioners made more home visits than their female counterparts (mean 12.8 v. 8.3 per week), although they spent an almost equal amount of time on this activity (mean 5.7 v. 5.2 hours per week). INTERPRETATION: These results suggest that practice patterns for home care vary according to the physician''s practice setting and sex. Because of foreseeable increases in the numbers of patients needing home care, further research is required to evaluate how physicians'' practices can be adapted to patients'' needs in this area.     

The health of Indians in Canadian cities: a challenge to the health care system

It is well known that Canadian native people living on reserves have high morbidity and mortality rates, but less is known about the health of those who migrated to urban centres. Several studies have shown that these people have high rates of mental health problems, specific diseases, injuries, infant death and hospital admission. In addition, there is evidence that cultural differences create barriers to their use of health care facilities. The low socioeconomic status, cultural differences and discrimination that they find in cities are identified as the primary blocks to good health and adequate health care. More epidemiologic studies need to be done to identify health problems, needs and barriers to health care. Federal, provincial and civic governments along with the appropriate departments of faculties of medicine should begin working with native organizations to improve the health of native people living in Canada''s cities.     

What factors influence primary care physicians' charges for their services? An exploratory study using standardized patients

OBJECTIVE: To determine the extent of variation in physicians'' charges for health care encounters with unannounced standardized patients and factors associated with the variation. DESIGN: Cross-sectional study. SETTING: Family practices open to new patients within 1 hour''s drive of Hamilton, Ont. PARTICIPANTS: A stratified random sample of 125 physicians who had responded to an earlier survey regarding preventive care were invited to participate. Of the 125, 44 (35.2%) declined to participate, and an additional 19 (15.2%) initially consented but later withdrew because they closed their practices to new patients. Sixty-two physicians thus participated in the study. INTERVENTION: Unannounced standardized patients posing as new patients to the practice visited study physicians'' practices between September 1994 and August 1995, portraying 4 scenarios: 28-year-old woman, 52-year-old woman, 48-year-old man and 70-year-old man. OUTCOME MEASURES: Physician characteristics, encounter characteristics and charges made for services. RESULTS: The 62 physicians had 246 encounters with the standardized patients. Charges were made to the health insurance plan for services by 59 physicians for up to 4 encounters (215 encounters in all). Charges varied considerably both within and across patient scenarios. Time spent with the patient was an important factor predicting charges made (p < 0.01), although the effect of time spent on charges varied across scenarios (p < 0.01). Fee-for-service physicians charged more for their services than physicians who usually had alternative billing arrangements (p < 0.01). Female physicians charged more for their services than their male colleagues (p = 0.03). No relation was found between quality of preventive care and charges made (p = 0.15). CONCLUSIONS: Physician-related factors are better able to account for the variability in charges for their services than patient-related factors. Physicians seeing comparable patients may earn much more or less than their colleagues because of differences in the services they provide and the way they apply the fee schedule. Quality-assurance techniques are likely needed to reduce the variability in charges seen and increase value for money spent in health care.     

Provision of preventive care to unannounced standardized patients

OBJECTIVE: To examine the relation between physician, training and practice characteristics and the provision of preventive care as described in the guidelines of the Canadian Task Force on the Periodic Health Examination. DESIGN: Cross-sectional study. SETTING: Family practices open to new patients within 1 hour''s drive of Hamilton, Ont. PARTICIPANTS: A total of 125 family physicians were randomly selected from respondents to an earlier preventive care survey. Of the 125, 44 (35.2%) declined to participate, and an additional 19 (15.2%) initially consented but later withdrew when they closed their practices to new patients. Sixty-two physicians thus participated in the study. INTERVENTION: Unannounced standardized patients posing as new patients to the practice visited study physicians'' practices between September 1994 and August 1995, portraying 4 scenarios: 48-year-old man, 70-year-old man, 28-year-old woman and 52-year-old woman. OUTCOME MEASURES: Proportion of preventive care manoeuvres carrying grade A, B, C, D and E recommendations from the Canadian Task Force on the Periodic Health Examination that were performed, offered or advised. A standard score was computed based on the performance of grade A and B manoeuvres (good or fair evidence for inclusion in the periodic health examination) and the non-performance of grade D and E manoeuvres (fair or good evidence for exclusion from the periodic health examination). RESULTS: Study physicians performed or offered 65.6% of applicable grade A manoeuvres, 31.0% of grade B manoeuvres, 22.4% of grade C manoeuvres, 21.8% of grade D manoeuvres and 4.9% of grade E manoeuvres. The provision of evidence-based preventive care was associated with solo (v. group) practice and capitation or salary (v. fee-for-service) payment method. Preventive care performance was unrelated to physician''s sex, certification in family medicine or problem-based (v. traditional) medical school curriculum. CONCLUSIONS: Preventive care guidelines of the Canadian Task Force on the Periodic Health Examination have been incompletely integrated into clinical practice. Research is needed to identify and reduce barriers to the provision of preventive care and to develop and apply effective processes for the creation, dissemination and implementation of clinical practice guidelines.     

Canadian departments of pediatrics and family medicine: in need of family therapy?

Whether and how much the departments of pediatrics in Canadian medical schools collaborate with the family medicine departments in training for child care were the focus of a survey conducted in 1983-84. Responses to a questionnaire sent to department heads indicated that in general the most supportive relationships existed in the western provinces, with progressively more problems uncovered from west to east. The responses concerning the roles of pediatricians and family physicians paralleled this trend, with the western view being that pediatricians are consultants and not competitors for primary care. Many respondents supported the expansion of family medicine, particularly into ambulatory and behavioural areas. The data provide some cause for concern about the future health care of children, as the forecasted oversupply of physicians is likely to encourage competition rather than consultation between the two groups. Also, many Canadian pediatricians accept the US model of pediatrics, which includes primary care, although in Canada the ratio of family physicians to pediatricians is six times that in the United States, and Canadian specialists are concentrated in urban centres. This means that family physicians will continue to provide most of the child care in Canada and need adequate training. They also need to develop cooperative, supportive relationships with specialists in child health care to enhance appropriate referral patterns.     

Patient morbidity and some patterns of family practice in southeastern Ontario.

Over a 7-month period the trial version of the International Classification of Health Problems in Primary Care (ICHPPC) was studied. Ten community physicians reported 28 399 encounters wtith 11 437 patients. The overall distribution of health problems was comparable to that found in other North American studies. Some differences between the morbidity distributions in urban and rural practices varies from those of previous Canadian studies. Other differences between practices appeared to be related to the interests and training of the individual physicians. The workload of the physicians varied considerably. Many of the encounters involved problems for which there may be minimal benefit from medical intervention, and there was a large discrepancy in the frequency of follow-up visits for specified stable chronic health problems. The implications of these interpractice variations in the altering field of health care are discussed.     

Jehovah's Witnesses leading education drive as hospitals adjust to no blood requests.

Jehovah''s Witness representatives have visited more than 10 Canadian medical schools and 200 hospitals in an attempt to educate future and practising physicians about nonblood medicine. The trend is becoming more popular since the advent of HIV, and there are now about 100 bloodless medicine and surgery centres around the world, including 52 in the US. However, a Jehovah''s Witness spokesman says Canada is "conspicuously absent" from the list of countries that offer bloodless-medicine programs.     

A survey of postgraduate training for family practice.

The results of a survey of Canadian primary care physicians for the Canadian Medical Association (CMA''s) Task Force on Education for the Provision of Primary Care Services are reported. Recent Canadian medical school graduates in primary care practice reported that the three major training routes (rotating and mixed internships and family medicine residencies) each prepared them differently for practice. The graduates of 2-year family medicine residencies were more satisfied with their preparation than were the graduates of the other major training routes. A 2- or 3-year family medicine residency was preferred by 50% of the respondents, although only 33% of them had actually taken one of these routes. There was considerable agreement in the respondents'' assessments of the types of postgraduate education needed for primary care practice. The results of this survey were consistent with the recommendations in the final report of the CMA''s task force.     

Age as a factor in breast cancer knowledge,attitudes and screening behaviour.

OBJECTIVE: To determine whether there are age-related differences in knowledge, attitudes and behaviour with respect to breast cancer and whether the differences reflect the age-specific Canadian recommendations on breast cancer screening. DESIGN: Telephone survey. SETTING: Two cities and five towns and their surrounding areas in Alberta. PARTICIPANTS: The age-specific, randomly selected sample comprised 1284 women aged 40 to 75 years who did not have breast cancer. Of the 1741 eligible women who were contacted, 1350 (78%) agreed to participate; 66 were excluded because of age ineligibility or a history of breast cancer. MAIN OUTCOME MEASURE: Frequency of knowledge, attitudes and behaviour with respect to breast cancer, by age group. RESULTS: Knowledge of breast cancer risk factors was generally low and decreased with age. Few women were aware of the Canadian recommendations on breast self-examination, physical examination of the breasts by a health care practitioner and mammographic screening. Older women believed they were less susceptible to breast cancer than younger women and were less likely to have positive attitudes toward screening. Self-examination was performed 9 to 15 times per year by 424 women (33%), and 810 (63%) had been examined by a health care professional in the past year. Although 664 (52%) had undergone mammography, the proportion decreased with age after age 59. The main barriers to mammography were lack of physician referral and the woman''s belief that the procedure is unnecessary if she is healthy. CONCLUSIONS: Education is needed to increase breast cancer knowledge, promote the Canadian recommendations for early detection of breast cancer and decrease negative beliefs about the disease. Changes in the behaviour of women and physicians are needed to increase the use of breast self-examination, clinical breast examination by a health care professional and mammographic screening. Reaching women in the upper range (60 to 69 years) of the target group for mammographic screening should be a focus in promoting early detection of breast cancer.     

Career and practice profiles of Alberta medical graduates (1973-85) practising in Alberta.

This collaborative study examined the career choices and practice locations of the 940 (58%) of the Alberta medical students graduating between 1973 and 1985 who remained in Alberta. Of the 686 practising graduates slightly less than two-thirds were in family/general practice; the remainder were in a specialty. More women (76%) than men (60%) had chosen family/general medicine. The women graduates spent about 10 hours less a week on patient care than their male colleagues. Personal and professional factors were cited most often as determinants of practice location. Approximately 20% of the practising graduates chose to locate in small towns or rural areas. Accessibility to consultants and opportunities for continuing medical education were reported as vital prerequisites for more physicians to move to smaller Alberta centres. These findings provide a starting point for studies designed to determine how Alberta medical school graduates are contributing to patient care within the province.     

Correlates of certification in family medicine in the billing patterns of Ontario general practitioners.

There is conflicting evidence as to whether physicians who are certified in family medicine practise differently from their noncertified colleagues and what those differences are. We examined the extent to which certification in family medicine is associated with differences in the practice patterns of primary care physicians as reflected in their billing patterns. Billing data for 1986 were obtained from the Ontario Health Insurance Plan for 269 certified physicians and 375 noncertified physicians who had graduated from Ontario medical schools between 1972 and 1983 and who practised as general practitioners or family physicians in Ontario. As a group, certificants provided fewer services per patient and billed less per patient seen per month. They were more likely than noncertificants to include counselling, psychotherapy, prenatal and obstetric care, nonemergency hospital visits, surgical services and visits to chronic care facilities in their service mix and to bill in more service categories. Certificants billed more for prenatal and obstetric care, intermediate assessments, chronic care and nonemergency hospital visits and less for psychotherapy and after-hours services than noncertificants. Many of the differences detected suggest a practice style consistent with the objectives for training and certification in family medicine. However, whether the differences observed in our study and in previous studies are related more to self-selection of physicians for certification or to the types of educational experiences cannot be directly assessed.     

The alluring myth of private medicine.

Canada''s medicare system has provided Canadians with high-quality health care for almost three decades. Now Canadian health care appears to be at risk of losing the single-payer system, which is the premise on which medicare is built. As medicare comes under increasing financial pressure, many are calling for the introduction of private care as a means of bolstering our health care system and maintaining its quality. Although it appears alluring to some politicians, physicians and commentators, privatization could very well lead to the demise of the principles and practices of the Canadian health care system as we know it, with little clear benefit to the public or physicians.     

Physicians' perceptions of the effect on clinical services of an alternative funding plan at an academic health sciences centre

BACKGROUND: In July 1994 an alternative funding plan for clinical services (global funding instead of fee-for-service payment) was established at the Southeastern Ontario Health Sciences Centre, Kingston, Ont. This study describes the perceptions of the referring physicians and consultants of the effects of the alternative funding plan 2.5 years after it was initiated. METHODS: A questionnaire was mailed to all physicians in the Kingston area in November 1996. Information was collected on demographics, referring physicians'' perceptions of the funding plan''s impact on their practices, consultants'' perceptions of its impact on their activities, perceptions of referring and consultant physicians of its impact on services provided by consultants, and attitudes toward alternative funding in the context of the Ontario health care system. RESULTS: Of the 772 physicians 531 (68.8%) returned a completed questionnaire (323 referring physicians and 208 consultants). A sizeable proportion of the referring physicians (126 [39.0%]) indicated that they were referring fewer patients to consultants at the study centre. They did not think that their practice volume had increased, but they did report spending more time on complex cases and on patient care after referral or hospital stay, and more time coordinating community care after hospital stay. Of the consultants 81 (38.9%) believed that their time spent on patient care had increased. No consistent impact on time spent on research or teaching activities was perceived. A total of 54 (26.0%) of the consultants were concerned about the impact of the alternative funding plan on quality of care. A significant proportion of the respondents (399 [75.1%]) believed that outpatient waiting times had increased, and 116 (35.9%) of the referring physicians believed that consultants were not as available by telephone. Most (220 [68.1%]) of the referring physicians believed that the funding change had had a negative effect on health care services in the region, and 87 (41.8%) of the consultants agreed. Nevertheless, the respondents believed that other factors such as funding cuts, hospital bed closures and staff layoffs were much more responsible than the alternative funding plan for their negative perceptions. INTERPRETATION: The alternative funding plan appears to have had an impact on the practices of individual physicians. However, it was not the focus for significant opposition or support from either consultants participating in the funding plan or referring physicians.     

Taking care of patients--does it matter whether the physician is a woman?

Researchers have recently begun to compare male and female physicians'' attitudes toward patients, medical knowledge, and practice styles. Although women start medical school with more "humanistic views," the conservative effect of medical socialization on both male and female students attenuates these differences. While some studies suggested that men are more scientifically knowledgeable, recent studies showed no significant differences in physicians'' medical knowledge. Male and female physicians also had comparable diagnostic and therapeutic behavior. In the intimate world of physicians and patients, however, there were notable differences. Women physicians seemed better able to communicate sensitivity and caring to patients, which may account for the common perception that women are more caring and empathic physicians. Medical educators may wish to study more closely female physicians'' communication styles to identify these behaviors and inculcate them into all physicians.     

Quality of care in family practice: does residency training make a difference?

As the proportion of physicians who enter residency training in family practice steadily increases, so does the need to evaluate the impact of their training and postgraduate education on the quality of care in their practices. We audited the practices of 120 randomly selected family physicians in Ontario, who were separated into four groups: nonmembers of the College of Family Physicians of Canada (CFPC), members of the CFPC with no certification in family medicine, certificated members without residency training in family medicine and certificated members with residency training in family medicine. The practices were assessed according to predetermined criteria for charting, procedures in periodic health examination, quality of medical care and use of indicator drugs. Generally the scores were significantly higher for CFPC members with residency training in family medicine than for those in the other groups, nonmembers having the lowest scores. Patient questionnaires indicated no difference in satisfaction with specific aspects of care between the four groups. Self-selection into residency training and CFPC membership may account for some of the results; nevertheless, the findings support the contention that residency training in family medicine should be mandatory for family physicians.     

Sex-related differences in coronary revascularization practices: the perspective from a Canadian queue management project.

OBJECTIVE: To assess sex-related differences in coronary revascularization practices in a Canadian setting. DESIGN: Prospective analytic cohort study. SETTING: Regional referral office in Toronto. PATIENTS: A selected but consecutive group of 131 women and 440 men referred by cardiologists for revascularization procedures between Jan. 3, 1989, and June 30, 1991. INTERVENTIONS: Coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA). Nurse-coordinators placed the referral with a surgeon or interventional cardiologist at one of three hospitals, who then communicated directly with the referring cardiologist. MAIN OUTCOME MEASURES: Symptom status at referral, procedures requested and performed, and time from referral to procedure. RESULTS: Although the women were more likely than the men to have unstable angina at the time of referral (odds ratio [OR] 2.28, 95% confidence interval [CI] 1.38 to 3.79, p = 0.0006), more women than men (16.8% v. 12.1%) were turned down for a procedure. Significant sex-related differences in practice patterns (p < 0.001) persisted after controlling for age or for the referring cardiologists'' perception of expected procedural risk. A stepwise multivariate model showed that anatomy was the main determinant of case management; sex was the only other significant variable (p = 0.016). The referring physicians requested CABG more often for men than for women (p = 0.009), and the men accepted for a procedure were much more likely to undergo CABG than the women (OR 2.40, CI 1.47 to 3.93, p = 0.0002). Although the women undergoing CABG waited shorter periods than the men (p = 0.0035), this difference was attributable to their more severe symptoms. CONCLUSIONS: In this selected group women had more serious symptoms before referral but were turned down for revascularization more often than men. Reduced use of CABG rather than PTCA largely accounted for the sex-related differences in revascularization. Once accepted for a procedure women had shorter waiting times, which was appropriate given their more severe symptoms.     

Universities and medical schools: reflections on a half-century of Canadian medical education.

After 50 years of accelerated development, universities and medical schools have entered a period of uncertainty and instability. The Flexnerian paradigm of medical education, rooted in biomedical science and conducted under the aegis of a university, reached its apotheosis by the late 1960s and the early 1970s. Fuelled by the introduction of comprehensive, government-sponsored health care insurance and advances in technology, the demand for health care professionals and for access to facilities increased sharply. Medical education, research and advanced clinical services expanded dramatically aided by the emergence of academic health sciences centres and accompanied by a wave of medical curriculum reform. Now medical schools must strike a dynamic balance in responding to the continued expansion of knowledge and technology, the demand for social equity and the exigencies of prolonged fiscal constraint. They must also balance the biological and sociological approaches to medicine in establishing the foundations for the future development of Canadian medical education.     

Health problems and health care for adolescents in residential facilities in Quebec.

The health problems of 160 adolescents in four residential facilities of the Quebec social welfare court were studied. At the time of admission 44% had at least one problem requiring consultation with a specialist and 80% had an average of two problems requiring primary care. The medical records of 106 youngsters in two re-education centres were also reviewed and similar results were noted. The health services available, particularly physical examination and laboratory testing at the time of admission and arrangements for referral and follow-up were judged to be insufficient in most centres. Although society has taken custody of these adolescents, no one is responsible for their health care. Since February 1976 the social welfare court residential facilities and the network involved in the care of socially disturbed youngsters have been undergoing reorganization. Health programs and services ought to be part of this reorganization, and private physicians, hospitals and government each should have a role in the establishment and functioning of these programs.     

Preventive practice among primary care physicians in British Columbia: relation to recommendations of the Canadian Task Force on the Periodic Health Examination.

OBJECTIVES: To compare the current practice of preventive medicine in British Columbia with the recommendations of the Canadian Task Force on the Periodic Health Examination. Four common, preventable forms of cancer (cervical, breast, lung and colorectal) were used as sentinel conditions. DESIGN: Random sample mailed survey. SETTING: Private primary care practices in British Columbia. PARTICIPANTS: A sample of 300 primary care physicians in 1991; of 285 eligible physicians 185 (65%) responded. OUTCOME MEASURE: Compliance with preventive practices recommended by the task force. RESULTS: Preventive practice complied with the task force''s recommendations for breast examinations, mammography, cervical smears and initial counselling against smoking; over 90% of the physicians performed these manoeuvres in all or most cases. However, less than half performed two recommended manoeuvres for all or most patients who smoke: advice to follow a diet high in beta-carotene (reported by 10%) and scheduling of follow-up visits to reinforce antismoking counselling (by 46%). Most of the physicians stated that they perform preventive manoeuvres in the context of an annual general physical examination rather than integrating them into routine patient care. CONCLUSIONS: The task force''s carefully constructed recommendations are incompletely followed. Overall, there appears to be a high level of compliance with traditional and recommended manoeuvres but also widespread persistence in performing traditional manoeuvres no longer recommended and failure to adopt new recommendations.
