Learning oral presentation skills: a rhetorical analysis with pedagogical and professional implications.

OBJECTIVE: Oral presentation skills are central to physician-physician communication; however, little is known about how these skills are learned. Rhetoric is a social science which studies communication in terms of context and explores the action of language on knowledge, attitudes, and values. It has not previously been applied to medical discourse. We used rhetorical principles to qualitatively study how students learn oral presentation skills and what professional values are communicated in this process. DESIGN: Descriptive study. SETTING: Inpatient general medicine service in a university-affiliated public hospital. PARTICIPANTS: Twelve third-year medical students during their internal medicine clerkship and 14 teachers. MEASUREMENTS: One-hundred sixty hours of ethnographic observation. including 73 oral presentations on rounds. Discoursed-based interviews of 8 students and 10 teachers. Data were qualitatively analyzed to uncover recurrent patterns of communication. MAIN RESULTS: Students and teachers had different perceptions of the purpose of oral presentation, and this was reflected in performance. Students described and conducted the presentation as a rule-based, data-storage activity governed by "order" and "structure." Teachers approached the presentation as a flexible means of "communication" and a method for "constructing" the details of a case into a diagnostic or therapeutic plan. Although most teachers viewed oral presentations rhetorically (sensitive to context), most feedback that students received was implicit and acontextual, with little guidance provided for determining relevant content. This led to dysfunctional generalizations by students, sometimes resulting in worse communication skills (e.g., comment "be brief" resulted in reading faster rather than editing) and unintended value acquisition (e.g., request for less social history interpreted as social history never relevant). CONCLUSIONS: Students learn oral presentation by trial and error rather than through teaching of an explicit rhetorical model. This may delay development of effective communication skills and result in acquisition of unintended professional values. Teaching and learning of oral presentation skills may be improved by emphasizing that context determines content and by making explicit the tacit rules of presentation.

Mycotic aneurysm presenting as Pancoast's syndrome in an injection drug user.

Injection drug users frequently present to emergency departments with fever. A careful history and physical examination with attention to anatomic localization of symptoms and signs are often necessary to unmask unusual underlying medical conditions. We report a case of a woman with recent injection drug use who presented with fever, a palpable neck mass, and Pancoast's syndrome. She had been seen recently at the ED of another hospital and discharged with oral antibiotics for presumed cellulitis. A mycotic aneurysm of the subclavian artery causing Pancoast's syndrome was later diagnosed by using computed tomography and angiography. A high index of suspicion for anatomically localized infective processes should always be maintained with febrile injection drug users.

Teaching and learning communication in medicine: a rhetorical approach.

The language people use both makes possible and constrains the thoughts they can have. More than just a vehicle for ideas, language shapes ideas--and the practices that follow from them. Thus, in medical education, teaching students how to talk about medical cases also teaches them how to think about patients and medical work, and how to define their relationships to both. Without a theoretical model, however, teaching efforts in this domain tend to be implicit and ad hoc, which can lead to serious problems. Rhetoric is one science that can deepen understanding of communication and improve teaching of this clinical skill. Rhetoric systematically studies the relationships between communication and its effects, between how things are named and how they are experienced, between discourse and socialization. Bringing language to the foreground of education, rhetoric directs attention to the relationship between what medical students learn to say and what they learn to value, believe, and practice.

Do ratings on the American Board of Internal Medicine Resident Evaluation Form detect differences in clinical competence?

OBJECTIVE: To determine whether raters using the American Board of Internal Medicine (ABIM) Resident Evaluation Form can detect differences among residents in clinical competence. DESIGN: Cross-sectional study. SETTING: Inpatient general medicine service in a university-affiliated public hospital. PARTICIPANTS: University-based internal medicine (UCIM) residents (ABIM certifying examination pass rate, 91%; mean score, 95th percentile), community hospital-based internal medicine (CHIM) residents (ABIM examination pass rate, 68%; mean score, 42nd percentile), and residents from three university-based non-internal medicine (UC non-IM) programs all assigned to the same inpatient general medicine service over a three-year period. Four hundred eighty-nine evaluations of 110 postgraduate-year-one residents were analyzed. MEASUREMENTS AND MAIN RESULTS: Mean ratings for the UCIM residents were significantly higher than those for the CHIM or UC non-IM residents (analysis of variance [ANOVA], p < 0.05). Variance was smallest for the UCIM residents (F test, p < 0.01), and only the UCIM residents' mean scores were in the "superior" range (7-9) in all evaluated categories. The mean ratings for the CHIM residents while at the university-affiliated hospital were not significantly different from the ratings of the same residents at their home hospital. The ratings for the CHIM residents at either site were significantly lower than those for the UCIM residents in all categories (ANOVA, p < 0.05). Factor analysis revealed a single factor accounting for 76% of the variance among the ratings with all dimensions loading high on that factor (0.75-0.95), providing evidence for a "halo" effect. Mean interrater agreement over all variables was 0.87, indicating good consistency among raters. CONCLUSIONS: Ratings on the ABIM Resident Evaluation Form detect global differences among residents in clinical competence in the expected direction based on type of training program and performance on the ABIM certification examination, but fail to differentiate among the nine evaluated dimensions of clinical care. This rating method may be valid for assessing overall clinical performance, but is less useful for providing feedback in specific areas to individual residents.

Sexual harassment in medical training.

BACKGROUND: Sexual harassment has become a national concern and one that is increasingly recognized in the field of medicine. Although there are reports of the sexual harassment of medical trainees, there is little information on the prevalence of this problem and whether it is adequately addressed by training institutions. METHODS: Surveys with descriptions and examples of sexual harassment were mailed to 133 internal medicine residents in a university training program. The residents were asked to report anonymously whether they had encountered sexual harassment during medical school or residency, the frequency and type of harassment, its effect on them, whether they chose to report it to a person in authority, and the factors that influenced this decision. RESULTS: Surveys were returned by 82 residents (response rate, 62 percent), 33 women and 49 men. Twenty-four women (73 percent) and 11 men (22 percent) reported that they had been sexually harassed at least once during their training. The women were more likely than the men to have been physically harassed, and the women's harassers were of higher professional status. Among those harassed, 19 of the women (79 percent) and 5 of the men (45 percent) thought that the experience created a hostile environment or interfered with their performance at work, but only 2 women and no men reported their experiences to an authority. The women cited a lack of confidence that they would be helped as the main reason for not reporting the experience, whereas men most commonly said that they had dealt with the problem without the need for outside assistance. CONCLUSIONS: Many medical trainees encounter what they believe to be sexual harassment during medical school or residency, and this often creates a hostile learning and work environment. Training institutions need to address the adverse effects this may have on medical education and patient care.

A risk-benefit analysis of elective bilateral oophorectomy: effect of changes in compliance with estrogen therapy on outcome.

A bilateral oophorectomy at the time of elective hysterectomy is often performed to prevent ovarian cancer. The assumption that endogenous estrogen can be easily replaced with supplemental medication fosters the decision for routine oophorectomy. Published reports on the use of postmenopausal estrogen indicate that compliance is less than perfect. This fact could affect the overall outcome. Decision analysis techniques with Markov cohort modeling were used to evaluate the policy of elective bilateral oophorectomy. Results from studies judged methodologically sound were combined to determine values representing the influence of estrogen on coronary heart disease, breast cancer, and osteoporotic fracture. The decision tree also explicitly incorporated patient compliance. When compliance with estrogen therapy is assumed to be perfect, oophorectomy yields longer life expectancy than retaining the ovaries. When actual drug-taking behavior is considered, retaining the ovaries results in longer survival. This analysis highlights the importance of including the effects of patient compliance with treatment recommendations when the impact of a health policy decision such as prophylactic surgery is assessed.

The status of hypertriglyceridemia as a risk factor for coronary heart disease.

The three-decade long controversy surrounding the status of triglycerides as an independent risk factor for coronary heart disease is presented. The studies that reported an association and the clinical trials of cholesterol-lowering medications are examined. Because of the inconsistency between the observational findings and the consistently negative clinical trial findings, treatment of isolated hypertriglyceridemia cannot be recommended at present.

Abortion deaths associated with the use of prostaglandin F2alpha.

Six abortion-related deaths associated with the use of prostaglandin F2alpha were reported through the Center for Disease Control's surveillance of abortion deaths between 1972 and 1975. Prostaglandin may have had only indirect association with these deaths. The patients' ages ranged from 16 to 38 years, their length of gestation ranged from 15 to 24 menstrual weeks, four were white, and three were nulliparous. Four patients had pre-existing conditions that increased their risks and contributed to their death. The estimated death-to-case rate for prostaglandin F2alpha was 10.5 per 100,000 abortions. Although lower than the rate for intra-amniotic saline instillation, this death-to-case rate is only an approximation. The relative safety of intra-amniotic prostaglandin F2alpha as a second-trimester abortifacient, compared to saline, remains to be established.

Medical complications from induced abortion by the super coil method.

PIP: 15 women in the second trimester of pregnancy underwent induced abortions in a private clinic in Philadelphia by the super coil method which was, from the scanty literature then available, purportedly safe and suited for second trimester pregnancies. This method utilizes a plastic strip 40 cm long and 4.6 mm wide, wound into a spiral 2 cm in diameter. The coil is straightened and put in an inserter through which it is introduced via the cervical os into the uterus. The method calls for insertion of several coils, and balsa tents may also be placed in the cervical canal. The coils are removed 12-24 hours after insertion, and if the uterine contents are not totally expelled spontaneously, ovum forceps are used to remove them. Neither of the 2 physicians performing the abortions had had previous experience with this method. 13 of the 15 women who underwent super coil abortions received follow-up medical evaluation. Of these 13, 9 (60%) had complications, 3 of which were major (2 requiring major surgery). Although the small number of women in this series does not permit a definitive judgement of the risks associated with the super coil method, the results do indicate that this method is not without significant risk and is in need of further research.^ieng

Termination of pregnancy by "super coils": morbidity associated with a new method of second-trimester abortion.

PIP: Follow-up of 15 women, aged 15-30 who underwent second-trimester abortion by "super-coil" showed that 9 women (60%) had some complications between the insertion of the coil and follow-up examination 1 week later. 7 of the women developed fever, 6 while the coils were still in utero. 11 of the women noted rupture of the membranes before the coil was removed. There were 3 major complications, one lacerated uterus requiring an abdominal hysterectomy, one case of periappendiceal inflamation with intrapelvic adhesions, and one case of postabortal anemia. Overall complication rates were higher for this group of patients than for other patients who underwent second-trimester abortion, as determined by the Joint Program for the Study of Abortion. The lack of experience of the operators and environment in which they were performed may have contributed to the high morbidity rate.^ieng
