Teaching clinical skills through videotape review: a randomized trial of group versus individual reviews.

BACKGROUND: Video review is a valuable educational tool for teaching communication skills. Many studies have demonstrated its efficacy with individual learners, but few studies have addressed its use in a group format. PURPOSE: To assess the educational benefits of group versus individual video review of standardized patient encounters through the evaluations of 4th-year students at the Albert Einstein College of Medicine. METHODS: Students (128) who participated in a 7-station, standardized patient, clinical competency exam were randomly assigned to an individual or small group video review of selected segments of these encounters in 2000-2001. Students filled out an anonymous 13-item questionnaire assessing the experience and provided open-ended responses. RESULTS: With both review formats, most students had a positive learning experience (80%), found it less stressful than they expected (67%), and would not have preferred to do the review the other way (84%). Students randomized to individual reviews had a significantly higher level of satisfaction with the amount of time for the session (91% vs. 78%, p < .05) and the amount of feedback they received (95% vs. 79%, p = .01) and were more likely to view the session as a positive learning experience (88% vs. 73%, p < .05). Students in the individual review format were more likely to choose self-assessed weak segments (63% vs. 49%, p = .01). Students' comments indicated that they appreciated the value of peer review in a group setting. CONCLUSIONS: Although both group reviews and individual reviews of videotaped standardized patient encounters were received well by the students, there were several statistical differences in favor of the individual format.

Community-based screening for cardiovascular disease and diabetes using HbA1c.

BACKGROUND: Persons from inner-city immigrant and mixed-ethnic communities are known to be at high risk for cardiovascular disease and diabetes. Such communities may also be underserved for preventive medical care. The authors hypothesized that hemoglobin A1c (HbA1c) could be used as a screening test for a community-based program to detect new cases of diabetes and persons at risk for diabetes and cardiovascular disease. METHODS: Screenings took place in churches, group homes, shelters, community centers, and street corners of the Bronx. Screening data included history of diabetes, age, ethnicity, body mass index, blood pressure, lipid panel, random glucose, and HbA1c. Data were analyzed for number of cases of new diabetes (HbA1c > or =7%), for patients at risk for diabetes (HbA1c 6%-6.99%), and for associations between HbA1c and other variables. The effect of location of screening and self-reported ethnicity on outcome variables was also analyzed. RESULTS: Seven hundred four persons were screened in 25 different sessions. HbA1c and lipid profile were obtained on 539 persons, which formed the cohort for analysis. Mean HbA1c for the cohort was 6.00%. Thirty-two percent of the cohort had HbA1c of more than 6%, and 11.4% had HbA1c of more than 7%. Excluding known diabetics (13% of cohort), 24% had HbA1c of more than 6%, and 3.4% had HbA1c of more than 7%. HbA1c was significantly correlated with total cholesterol, triglycerides, low-density lipoprotein, systolic blood pressure, body mass index, and age; in all cases, correlation coefficients were higher with HbA1c than with random glucose. In addition, significantly higher cardiovascular disease risk factors were found in persons with HbA1c of more than 6%; 6% may be a threshold value for the metabolic syndrome. Mean HbA1c was higher in persons from the South Bronx (which has a higher poverty rate) than the North Bronx (6.08% v 5.74%, p=0.013). There were no statistically significant differences between self-reported ethnic groupings. CONCLUSIONS: There was a high prevalence of undiagnosed diabetes, and of patients at risk for diabetes, in this community setting. Community-based screening can be used as a method for identifying high percentages of patients at risk for diabetes or with undiagnosed diabetes in an inner city, immigrant, mixed-ethnic population.

Using the case-discussion method to teach epidemiology and biostatistics.

Medical students must learn the principles of epidemiology and biostatistics to critically evaluate the medical literature. However, this subject has traditionally been difficult to teach. In 1997 at the Albert Einstein College of Medicine, the required first-year course in epidemiology and biostatistics was revised to use the case-discussion teaching method. In preparation for the course, experienced faculty participated in an intensive, two-day training workshop. The course, taught to 163 first-year medical students, was structured in two parts: (1) three lectures complemented by a detailed syllabus, followed by a multiple-choice midterm exam; and (2) six case-discussion seminars, followed by a short answer/essay final exam. There were seven case-discussion groups with 23-24 students each. The program was evaluated using subjective faculty feedback, examination scores, and student evaluation questionnaires. Faculty noted excellent student preparation and participation. Multiple-choice exam scores were comparable to those from earlier years, and a short answer/essay exam demonstrated good student mastery of the required material. Student evaluation was overwhelmingly positive, and significantly improved from prior years of the course. Positive student evaluations of the course using this teaching method continued over the next four years; National Board of Medical Examiners examination scores indicated success in mastery of the material; and student assessment of the course improved on the AAMC Graduation Questionnaire. This favorable experience suggests that case-discussion teaching can be employed successfully in teaching principles of epidemiology and biostatistics to medical students.

The internal medicine subinternship: a curriculum needs assessment.

Despite broad acceptance of the internal medicine subinternship rotation by the undergraduate medical education community, only a small fraction of programs provide students with explicit learning objectives. To design a curriculum for the medical subinternship, we surveyed 3 different groups of educational stakeholders--subinternship directors, residency program directors, and housestaff--in order to identify and prioritize the competencies that should be learned during this rotation. This study provides a starting point for the development of a structured curriculum for the fourth-year subinternship rotation.

Diabetes and stress hyperglycemia associated with myocardial infarctions at an urban municipal hospital: prevalence and effect on mortality.

Municipal hospitals in large cities provide care for patients from immigrant and mixed ethnic communities that are at high risk for diabetes. Both diabetes and stress hyperglycemia increase the risk of adverse outcome after myocardial infarctions, and the impact of stress hyperglycemia on the outcome of myocardial infarctions in this particular setting has not been previously studied. We therefore undertook a retrospective cohort study to determine the prevalence of diabetes and stress hyperglycemia in patients presenting to a university-affiliated Bronx municipal hospital with myocardial infarction, and the relationship of these conditions to the extent of coronary disease and mortality. We obtained data on 106 consecutive patients from July 1998 to April 1999 with a diagnosis-related group diagnosis of either myocardial infarction or acute coronary syndrome, in which myocardial infarction was confirmed by serum enzymes or characteristic electrocardiographic changes. Patients were followed until March 30, 2001. Measurements of clinical parameters and results of catheterization were obtained for all patients. Death rates were determined by laboratory database, direct patient contact, or data from National Death Index. Eighty percent of the cohort had either a diagnosis of diabetes (n = 45, 42% of cohort) or evidence of stress hyperglycemia (defined as serum glucose greater than 126 mg/dL at the time of admission without prior diagnosis of diabetes, n = 40, 38%). In-hospital mortality for patients with diabetes, stress hyperglycemia, or normal glucose was 20%, 15%, and 14%, respectively. Eighty-three percent of the cohort received beta blockers, and 61% of hospital survivors had catheterization. Left main or triple vessel disease was common in both patients with diabetes (52%) and patients with stress hyperglycemia (32%). Mortality at follow up (maximum follow up 3 years; mean follow up 19.6 months) was much higher in patients with either diabetes (42%) or stress hyperglycemia (52%) than normal subjects (24%). Kaplan-Meier analysis of the difference in mortality between patients with high glucose on admission and normal subjects was borderline significant (P = 0.06). Multivariate regression demonstrated that age (P = 0.020), increase in admission serum creatinine (P = 0.001), and reduction in either ejection fraction (P = 0.016) or admission systolic blood pressure (P = 0.005) were significant predictors of mortality. Glycemic status and sex were not independently associated with death after controlling for these other factors. These results show that the prevalence of both diabetes and stress hyperglycemia on presentation with myocardial infarction is strikingly high in this immigrant, mixed ethnic, urban population. Patients with diabetes and stress hyperglycemia had advanced disease on presentation and much higher mortality at 2 to 3 years than those with normal blood glucose. The mortality difference is the result of older age and more advanced disease rather than hyperglycemia per se.
