Medical faculty as humanistic physicians and teachers: the perceptions of students at innovative and traditional medical schools.

BACKGROUND AND OBJECTIVES: The training of caring physicians represents an important goal of medical education. Little is known however, on whether medical faculty constitute good role models for teaching humanistic skills to medical students. In this study, we examined to what extent medical students at innovative and traditional schools perceived their teachers as humanistic physicians and teachers. We also explored whether pre-clinical and clinical students shared the same perceptions. METHODS: A mail survey was conducted in Canada of all second-year students and senior clerks at one innovative medical school (problem-based learning (PBL), patient-centred, community-oriented) and three traditional medical schools. Students were asked to what extent they agreed or disagreed that the majority of their teachers behaved as humanistic physicians and teachers; 10 statements were used. Overall, 65% of the 1039 students returned the questionnaire. RESULTS: Over 25% of second-year students and 40% of senior clerks did not agree that their teachers behaved as humanistic caregivers with patients or were good role models in teaching the doctor-patient relationship. More than half of second-year students and senior clerks did not agree that their teachers valued human contact with them or were supportive of students who had difficulties. There were few differences in the way medical students at innovative and traditional schools perceived their teachers' humanistic qualities. At the pre-clinical level however, there were more students from the innovative school than from the traditional schools (around 60% vs. 40%, P < 0.005) who agreed that their teachers valued human contact with them and were supportive of students. CONCLUSION: Our results indicate that the PBL curriculum fosters better teacher-student relationships during the pre-clinical years. They also suggest that an unacceptably large number of medical students are taught by physicians who seem to lack compassion and caring in their interactions with patients. This study questions the adequacy of medical faculty as role models for the acquisition of caring competence by medical students.

Clinical teachers as humanistic caregivers and educators: perceptions of senior clerks and second-year residents.

BACKGROUND: The acquisition and nurturing of humanistic skills and attitudes constitute an important aim of medical education. In order to assess how conducive the physician-learning environment is to the acquisition of these skills, the authors determined the extent to which clinical teachers are perceived by their trainees as humanistic with patients and students, and they explored whether undergraduate and graduate students share the same perceptions. METHODS: A mail survey was conducted in 1994/95 of all senior clerks and second-year residents at Laval University, University of Montreal and University of Sherbrooke medical schools. Of 774 trainees, 259 senior clerks and 238 second-year residents returned the questionnaire, for an overall response rate of 64%. Students' perceptions of their teachers were measured on a 6-point Likert scale applied to statements about teachers' attitudes toward the patient (5 items) and toward the student (5 items). RESULTS: On average, only 46% of the senior clerks agreed that their teachers displayed the humanistic characteristics of interest. They were especially critical of their teachers' apparent lack of sensitivity, with as many as 3 out of 4 declaring that their teachers seemed to be unconcerned about how patients adapt psychologically to their illnesses (75% of clerks) and that their teachers did not try to understand students' difficulties (78%) or to support students who have difficulties (77%). Compared with the clerks, the second-year residents were significantly less critical, those with negative perceptions varying from 27% to 58%, 40% on average. Except for this difference, their pattern of responses from one item to another was similar. INTERPRETATION: This study suggests the existence of a substantial gap between what medical trainees are expected to learn and what they actually experience over the course of their training. Because such a gap could represent a significant barrier to the acquisition of important skills, more and urgent research is needed to understand better the factors influencing students' perceptions.

Use of standardized patients to assess between-physician variations in resource utilization.

CONTEXT: As medical costs are increasingly being scrutinized, there is heightened interest in defining variations in physician behavior in clinical settings. OBJECTIVE: To evaluate if standardized patient (SP) technology is a reliable and feasible method of studying interphysician variations in test ordering, referral requests, prescribing behavior, and visit costs. DESIGN: The study was conducted with blinded SP visits to family medicine and internal medicine residents, university-affiliated family physicians, and community-based family physicians. Resource utilization and visit costs were assessed using test requisitions, consult requests, and prescriptions that were collected by the SPs. SETTING: Physicians' offices in ambulatory care, hospital-based clinics and in the community. PARTICIPANTS: Four persons (aged 57-77 years) trained to simulate having osteoarthritis of the hip. In one simulation, the patient had gastropathy due to nonsteroidal anti-inflammatory drug use, and in the other, the patient sought therapy for hip discomfort. MAIN OUTCOME MEASURES: Reliability of cost estimates of physician services, tests, consultations, prescriptions, and total visits and test-ordering behavior for nonsteroidal anti-inflammatory gastropathy. RESULTS: Overall, 112 (63%) of the physicians who were sent invitations to the study agreed to participate. Of 312 total SP visits conducted over a 1-year period, unblinding due to SP detection occurred on 36 occasions (11.5%). Reliable cost estimates of physician services, tests, and consultations, and moderately reliable estimates of total visit costs, were obtained with 4 visits per practicing physician and with 2 visits per resident. There were extreme variations in total visit costs generated by the study physicians. A small number of physicians had a major impact on this variability. CONCLUSION: Standardized patient technology provides a reliable, feasible method to assess variations in resource utilization between physicians.

Unnecessary prescribing of NSAIDs and the management of NSAID-related gastropathy in medical practice.

BACKGROUND: Use of nonsteroidal anti-inflammatory drugs (NSAIDs) increases the risk for hospitalization and death from gastrointestinal bleeding and perforation. OBJECTIVES: To 1) estimate the extent to which NSAIDs are prescribed unnecessarily and NSAID-related side effects are inaccurately diagnosed and inappropriately managed and 2) identify the physician and visit characteristics associated with suboptimal use of NSAIDs. DESIGN: Prospective cohort study. SETTING: Montreal, Canada. PARTICIPANTS: 112 physicians representing academically affilliated general practitioners, community-based general practitioners, and residents in family medicine and internal medicine. INTERVENTIONS: Blinded, office-based assessment of the management of two clinical cases (chronic hip pain due to early osteoarthritis and NSAID-related gastropathy) using elderly standardized patients. MEASUREMENTS: Quality of drug management and potential predictors of suboptimal drug management. RESULTS: Unnecessary prescriptions for NSAIDs or other drugs were written during 41.7% of visits. Gastropathy related to NSAID use was correctly diagnosed in 93.4% of visits and was acceptably managed in 77.4% of visits. The risk for an unnecessary NSAID prescription was greater when the contraindications to NSAID therapy were incompletely assessed (odds ratio, 2.3 [95% CI, 1.0 to 5.2]) and when the case was managed by residents in internal medicine (odds ratio, 4.1 [CI, 1.2 to 14.7]). The risk for suboptimal management of NSAID-related side effects was increased by incorrect diagnosis (odds ratio, 16.6 [CI, 3.6 to 76.5]) and shorter visits. CONCLUSIONS: Unnecessary NSAID prescribing and suboptimal management of NSAID-related side effects were sufficiently common to raise questions about the appropriateness of NSAID use in the general population. If these results reflect current practice, prescribing patterns may contribute to avoidable gastrointestinal morbidity in elderly persons.

Analysis of Centers for Disease Control and Prevention criteria for the eosinophilia-myalgia syndrome in a geographically defined population.

OBJECTIVE: To test whether individuals can be identified in a geographically defined population who would meet criteria for the eosinophilia-myalgia syndrome (EMS) established by the US Centers for Disease Control and Prevention (CDC), i.e, (1) eosinophil count > 1 x 10(9)/l, (2) myalgia severe enough to limit usual activities of daily living, and (3) no evidence of infection or neoplasm that could explain the first 2 findings. METHODS: To discover the number of individuals who would meet CDC criteria, the population was exhaustively searched using methods adapted from active pharmacoepidemiologic surveillance. Medical consultants and primary care practitioners were questioned as many as 5 times in a search for patients with severe myalgia. A predetermined protocol was used to screen those patients who appeared to meet CDC criteria for EMS using active surveillance methods. The study population was limited to Québec and Ontario (combined population 18,980,000) with special attention to the period July 1, 1992, to June 30, 1993. RESULTS: The prevalence of severe incapacitating myalgia was 43 per 100,000 persons, including 19 individuals with eosinophilia > 1 x 10(9)/l, who met CDC criteria for EMS. None of these individuals were reported to have taken L-tryptophan (LT). CONCLUSION: The CDC criteria for EMS are met by individuals in the general population who have never been exposed to LT.

Continuing occurrence of eosinophilia myalgia syndrome in Canada.

Eosinophilia myalgia syndrome (EMS), was defined by the Centers for Disease Control (CDC) as eosinophilia > 1000 mm3 and incapacitating myalgia without infection or neoplasm. Studies suggested that use of L-tryptophan (L-T), was a risk factor. We conducted a pharmacoepidemiological survey in Canada where access to L-T is limited. Using the active surveillance method, a 100% sample of potentially involved specialists and a 15% sample of family physicians from Ontario and Quebec were surveyed regarding treatment of patients with severe myalgia within the past year. Follow-up amplified clinical and laboratory information. Overall response rates were 61.4%. Thirty-eight per cent of respondents reported at least one patient. Of 6423 patients assessed, 19 'definite' and 25 'possible' EMS cases were identified. Information from physicians did not suggest use of L-T in patients with definite or possible EMS. It was considered that the cases found an underestimate of the incidence of EMS. Its continuing occurrence in Canada brings causal interpretations of earlier studies into question.

Questionable prescribing for elderly patients in Quebec.

OBJECTIVE: To estimate the prevalence of questionable and rational high-risk prescribing among elderly people of the three drug groups most commonly implicated in drug-related illness: cardiovascular drugs, psychotropic drugs and nonsteroidal anti-inflammatory drugs (NSAIDs). DESIGN: Retrospective prevalence study; all prescription and billing records for the period Jan. 1 to Dec. 31, 1990, for the study sample were retrieved from the relevant provincial databases of the Régie de l'assurance-maladie du Québec. SETTING: Quebec. PARTICIPANTS: Regionally stratified random sample of 63,268 elderly medicare registrants who made at least one visit to physician in 1990 and were not living in a health care institution for the entire year. MAIN OUTCOME MEASURE: Prescription information was examined for three types of high-risk prescribing: rational and questionable drug combinations, excessive treatment duration and drugs relatively contraindicated for use in elderly people. RESULTS: Overall, 52.6% of the patients experienced one or more events of high-risk prescribing, and 45.6% experienced at least one that was questionable. High-risk prescribing was most prevalent for psychotropic drugs, and questionable prescribing was more frequent than rational prescribing in this drug group. An estimated 30.8% of the total elderly population in Quebec received benzodiazepines for more than 30 consecutive days, 12.9% received a long-acting benzodiazepine, and 13.0% received a questionable high-risk psychotropic drug combination. The prevalence of high-risk prescribing was higher among the women than among the men and increased with age until 75 to 84 years. There were significant unexplained differences between regions in the regional prevalence of high-risk prescribing, particularly of psychotropic drugs. CONCLUSION: The prevalence of questionable high-risk prescribing, especially of psychotropic drugs, is substantial among elderly people. This may be a potentially important and avoidable risk factor for drug-related illness in elderly people.

Hand function in the elderly: relation to osteoarthritis.

Hand function and osteoarthritis (OA) were assessed in 32 subjects, over 60-years-old. The Smith Hand Function Test bore a relation to age, coordination and hand strength but not to the degree of OA. Hand strength also was not related to OA. Subjective hand disability, measured with the Stanford Health Assessment Questionnaire, correlated with radiographic OA and joint tenderness as well as with sex and hand strength. OA does not contribute significantly to the objective decline in hand function in the elderly but may contribute to a subjective sense of functional limitation.
