From the desert: transcultural aspects of cancer nursing care in Israel

BACKGROUND: Medical students may be at high risk for occupational exposures to blood. OBJECTIVE: To measure the frequency of medical students' exposure to infectious body substances, to identify factors that affect the probability of such exposure, and to suggest targets for the prevention of such exposure. DESIGN: Review of all exposures reported by medical students at the University of California, San Francisco, School of Medicine. SETTING: Teaching hospitals affiliated with the University of California, San Francisco. PARTICIPANTS: Third- and fourth-year medical students from the classes of 1990 through 1996 at the University of California, San Francisco, School of Medicine. INTERVENTIONS: A needlestick hotline service was instituted at teaching hospitals affiliated with the University of California, San Francisco, and a required course was created to train students in universal precautions and clinical skills before the beginning of the third-year clerkship. MEASUREMENTS: Reports of exposures made to the needlestick hotline service, including type of exposure, training site, clerkship, and time of year. RESULTS: 119 of 1022 medical students sustained 129 exposures. Of these exposures, 82% occurred on four services: obstetrics-gynecology, surgery, medicine, and emergency medicine. The probability of exposure was not related to graduation year, clerkship location, previous clerkship experience, or training site. Surveys of two graduating classes at the beginning and end of the study showed that the percentage of exposures reported increased from 45% to 65% over the 7-year study period. Thus, the reported injury rates represent minimum estimates of actual occurrences. Human immunodeficiency virus infection and hepatitis were not reported, although follow-up was limited. CONCLUSIONS: Instruction in universal precautions and clinical procedures is not sufficient to prevent exposures to blood during medical training. Medical schools must assume greater responsibility for ensuring that students are proficient in the safe conduct of clinical procedures and must develop systems that protect students so that they can report and learn from their mistakes.     

Chromosomal assignments of the genes for the calcineurin A alpha (Calna1) and A beta subunits (Calna2) in the rat

PURPOSE: To document the characteristics of the clinical education in internal medicine of undergraduate medical students at Canadian medical schools. METHOD: A five-part questionnaire was sent in 1991-92 to the individuals responsible for supervising the internal medicine clerkships at all 16 Canadian medical schools. The questions were related to (1) tutors, hospitals, and inpatient clinical experiences of internal medicine clerks; (2) ambulatory care experiences; (3) evaluation methods; (4) "junior clerkships" (i.e., clinical courses that precede the clerkships); and (5) supervisors' opinions about changes needed to improve the clerkships. RESULTS: Responses were received from all schools. There was surprising uniformity in clinical education across Canada. Clinical education methods have changed very little over the past decade. In the opinion of the clerkship supervisors, there were too few committed clinical tutors, little evidence of use of newer evaluation methods, and inadequate ambulatory care instruction. CONCLUSION: The study results suggest that the clinical education in internal medicine of undergraduate medical students has changed little despite numerous calls for reform.     

Implementing problem-based learning in a family medicine clerkship

BACKGROUND AND OBJECTIVES: Problem-based learning (PBL) has been implemented in the curriculum of many medical schools, but limited information is available about the outcome of this learning technique. The educational intervention presented in this paper implemented a PBL learning component in our third-year family medicine clerkship and measured the outcomes of this curricular change. METHODS: One third of the curricular time devoted to didactic teaching in our family medicine clerkship was replaced with PBL activities. Simulated cases were developed and presented to students who, with the aid of faculty facilitators, studied the cases, gathered information about the cases, and developed diagnostic and management plans for the cases. The outcome of the intervention was measured by a) comparing students' scores on the National Board of Medical Examiners (NBME) family medicine clerkship examination to scores achieved by students in the year before PBL was introduced and b) students' evaluations of the relevance and success of PBL in the clerkship curriculum. RESULTS: Students' NBME clerkship examination scores increased from a mean of 66 the year before PBL began to 73 after PBL was implemented. More than 80% of students reported that PBL was a good way to learn family medicine, and 85% reported that the PBL technique provided sufficient information to formulate learning issues. CONCLUSIONS: PBL can be introduced into a third-year family medicine clerkship curriculum with general acceptance by students. Students rated the technique highly, and their examination scores improved.     

Chinese herbs: a clinical review of Astragalus, Ligusticum, and Schizandrae

BACKGROUND AND OBJECTIVES: The objective structured clinical exam (OSCE) is increasingly being used to evaluate student clinical performance. However, scant literature exists pertinent to this approach in evaluating family medicine clerkship performance. In this study, we assess 8 years' experience with a family medicine clerkship OSCE. METHODS: Eight annual clerkship OSCEs and the performance of 696 students are described. Comparisons of faculty evaluation, written exam, and OSCE performance are made for 335 students. Post-OSCE student and faculty feedback regarding OSCE validity and utility is also presented. RESULTS: Student performance is highest in medical history taking and physical examination and lowest in information-sharing stations. OSCE results appear to be relatively consistent on a year-to-year basis. OSCE, faculty evaluation, and written exam results have low overall levels of correlation, particularly in assessing performance that differs substantially from the mean. Students and faculty agree that the OSCE experience reflects skills that students should possess, but there is less agreement that the OSCE reflects clerkship-related learning and actual student performance. Both students and faculty derive insight from the OSCE regarding the definition of specific learning needs. CONCLUSIONS: The family medicine clerkship OSCE we describe appears to provide consistent measures of student performance. Although content validity is high, further assessment is needed to assure construct validity. The OSCE experience provides students with a rich resource for defining clerkship-related learning needs. Study results strongly suggest that OSCEs, faculty evaluations, and written exams provide differing measures of student performance. The reasons for these differences merit further exploration.     

Changes in medical students' perceptions of family practice resulting from a required clerkship

BACKGROUND: Career choice research has shown that exposing medical students to family medicine, through a special medical school emphasis or a required clerkship, correlates with an increased rate of selection of family practice. It has been hypothesized that actual exposure to family medicine mitigates the negative stereotypes held by many medical students. METHODS: This study used a qualitative strategy to examine how a family medicine clerkship altered medical students' perceptions and attitudes toward this specialty. A series of 12 focus groups were conducted with the students who had just completed a required family medicine junior core clerkship at our institution. RESULTS: Focus group findings confirmed the existence of negative stereotypes about family practice among medical students and provided additional information on their nature and origins. In addition, student comments indicated that a third-year family medicine clerkship experience dispelled this negative stereotyping and instilled in students a greater respect for and interest in family practice. CONCLUSION: Third-year clerkships can enhance students' perceptions of family practice by dispelling negative stereotypes and by providing medical students with a more accurate portrayal of the nature of this primary care specialty.     

A process for identifying marginal performers among students in a clerkship

PURPOSE: To evaluate a review process for identifying marginal performers among students in a clerkship. METHOD: To better identify the marginal performers among the students participating in the medicine clerkship at the University of Minnesota Medical School--Minneapolis, the Medicine Clerkship Committee reviewed in 1990-91 and 1991-92 all students rated by faculty or housestaff as below expectations for any of nine areas of clinical performance (27 students of 890, 3%). (In the past, a student was considered to be a marginal performer only if he or she was assigned an unsatisfactory numerical grade, calculated from the nine ratings, or if written comments by housestaff and faculty and the opinions of the attending faculty and clerkship site coordinator indicated that the student should fail.) Chi-square analysis was used to compare the number of students judged to be marginal performers under the review process with the number of marginal performers in 1988-89 and 1989-90. The two groups were also compared based on their preclerkship performances on standardized examinations. RESULTS: Ten of those reviewed (37%) were judged to have performed marginally. Although the study group's performance on standardized examinations was not different from that of students during the previous two years, significantly fewer students were identified as marginal performers before the review process began than afterwards (2 of 867, 0.2%, versus 10 of 890, 1.1%, p < .05). CONCLUSION: Without changing the way in which faculty and housestaff evaluated students, the review process improved the medicine clerkship evaluation system by identifying significantly more students who were marginal performers.     

Choice of first line treatment for arterial hypertension: should one avoid dihydropyridines in diabetic patients?]

The learning experience during a medical school clinical rotation is largely shaped by students' patient encounters. This paper reports on how a log system for recording these encounters can be used for course planning and evaluation. Over the past 5 years, 960 third-year students completed log forms based on their clinical encounters during a required 4-week family medicine clerkship at UT Southwestern. These forms were then optically scanned and the information entered into a computerized database. Log form data revealed that the most common medical problems encountered by students in their ambulatory settings were similar to those reported in the general family practice literature. There was a great deal of consistency in the types of encounters from year to year. The data also showed some differences among clerkship sites in terms of patient demographics and the most frequently reported diagnoses. Information generated from student log forms has been used by the clerkship faculty to determine required readings, prioritize didactic topics and other teaching, adjust curriculum content, prepare support materials and develop examinations. Given the utility of the information obtained and the ease of use of optical mark encounter sheets, we recommend this system for other clerkships.     

Performance on the radiology component of a critical clinical skills examination

RATIONALE AND OBJECTIVES: Clinical competence certification is now required in some specialties in medicine. A Comprehensive Clinical Assessment (CCA) was created to test mastery of critical skills by students at the end of the 3rd year of medical school. METHODS: The CCA is a series of stations that test skills the faculty consider important for all medical students (eg, breast examination, electrocardiogram reading, chest pain assessment, ophthalmology photographs). The radiology station was designed to evaluate imaging skills believed to be taught and learned in the core 3rd-year rotations. RESULTS: External measures (National Board Examinations, grade point average, and overall score) of clinical performance of the 608 medical students who completed the CCA examination between 1991 and 1993 were found to be correlated with the radiology station scores. CONCLUSION: The radiology station in the CCA examination is a reproducible measure of clinical performance.     

Educational programs in US medical schools, 1996-1997

We use data from the 1996-1997 Liaison Committee on Medical Education Annual Medical School Questionnaire, which had a 100% response rate, to describe medical education programs in the United States. In the 1996-1997 academic year, there were 95 568 full-time medical school faculty members, a 4.5% increase from 1995-1996. In clinical departments, the largest increases were in emergency medicine (a 29% increase from 1995-1996) and family medicine (a 13% increase). Of all full-time faculty members in clinical departments, 76.9% have an MD or DO as the highest degree, 4.5% have both an MD and PhD, 13.9% have a PhD, and 4.7% have an academic or professional bachelor's or master's degree as their final degree. The total number of applicants for the class entering in 1996 was 46968 (0.8% increase from 1995), while the number of first-time applicants decreased 1% from 1995. First-year medical students who were members of underrepresented minority groups numbered 2236, a 4% decrease from 1995. In 1996-1997, the total number of medical students was 66712 (0.3% less than in 1995-1996). For students graduating during the 1995-1996 academic year, 13% took longer than 4 years to complete the program. There were 47 medical schools that reported that 1 or more hospitals used for required clinical clerkships had changed ownership, merged, or closed during 1996. Medical schools used an average of 6 (range, 1-36) hospitals for core clinical clerkship. Ninety-five schools required a passing grade on Step 1 of the US Medical Licensing Examination (USMLE) for promotion or graduation; 54 schools required a passing grade on Step 2 of the USMLE.     

The art of mentoring

While the golden era of mentoring may have been the age of apprentice ships in medicine, the birth of the clinical clerkship in the late 1800s provided the structure for the relationship between faculty and medical student. The last few decades, however, have seen a dramatic change in the availability of faculty to mentor students in clinical teaching settings despite a 600% increase in the number of clinical full-time medical school faculty. This work explores some of the reasons for this deterioration in mentoring and looks at the role of the mentor in professional development, specifically in the area of medical education. Recommendations for implementing structured mentoring programs within a department of surgery are provided. The article concludes with discussion of individual characteristics of the effective mentor in surgical education.     

A randomized trial of physicians and physical therapists as instructors of the musculoskeletal examination

OBJECTIVE: To evaluate the effectiveness of physicians vs physical therapists as instructors of the musculoskeletal examination to second year medical students. METHODS: A randomized trial conducted over 3 consecutive years in a physical diagnosis course at The University of North Carolina. During the first (baseline) year, medical students received education about the musculoskeletal examination from a lecture and supervision by clinical preceptors. This increased in the second and third (intervention) years where random halves of each class received supplementary clinical instruction which included a structured manual, a videotape, and supervised practice with either general internal medicine physicians or physical therapists. Outcomes were measured from student performance on a practical test of clinical skills, and by written student evaluations of the supplementary instruction. RESULTS: As measured on the clinical examination, performance during the intervention years improved over that during the baseline year in both intervention groups. Measures of medical students' clinical skills did not correlate with measures of academic aptitude. CONCLUSIONS: Clinical education about the musculoskeletal examination should be structured and systematic. Medical students prefer clinical education that is active, provides clear directions, and gives them performance feedback.     

Evaluation of a method to teach cardiothoracic surgery to medical students

This report describes a method to teach undergraduate students the knowledge base and skills needed to maximize the educational value of a subsequent cardiothoracic surgical clerkship. Sixty-three fourth year medical students underwent a structured teaching programme in which groups of five students rotated through a series of six teaching stations. Subject material, presented during 20 min at each station, covered the key issues relating to coronary artery disease, congenital heart disease, chest trauma, lung cancer, prosthetic heart valves, pacemakers, thoracic sepsis and dysphagia. Group knowledge increased significantly (P < 0.001) from a mean mark of 23% (s.d. 12) in a pre-test to a mean mark of 46% (s.d. 12) in a test conducted 1 month after the teaching. The time taken to conduct the structured teaching/assessment was 5 h compared with 32 h to run the same programme by the traditional ward tutorial system. The dollar cost to stage the structured teaching was less than that to run the traditional tutorial programme. It was concluded that the teaching method is effective, economical and practical and that it has a role in an undergraduate curriculum to prepare students for clinical clerkship.     

Evaluation of student performance in a multi-site clinical clerkship

A method for examining the equivalency of student performance in multi-site clinical clerkships is presented. Six student performance variables within the clerkship are explored: pretest, posttest, oral examination, presentation of a subject review, general clinical performance, and patient write-ups. Student achievement on two external examinations (a University of Washington School of Medicine third-year comprehensive examination and the Part II examination of the National Board of Medical Examiners) is reviewed and compared. This method applied to an obstetrics and gynecology clerkship at the University of Washington reveals no significant differences in student performance among sites on the pretest, oral examination, and both external examinations, but there were differences on four internal measures (posttest, presentations, write-ups, and clinical ratings). The use of this information for clerkship improvement and faculty development is described.     

Sumatriptan nasal spray (20 mg/dose) in the acute treatment of cluster headache

BACKGROUND: Family medicine predoctoral programs frequently have medical students record patient diagnoses in logbooks. Little is known about the accuracy of such logbooks. No studies have compared patient records dictated by students with cases recorded in logbooks. METHODS: Over 2 years, all patient encounters dictated by 79 medical students during their 8-week family medicine rotations were recorded and compared with information in the students' logbooks. RESULTS: Students dictated 2,520 patient encounters but only recorded 2,085 (82.7%) of them in their logbooks. Still, this rate of inclusion is higher than other studies where students did not dictate patient encounters. On the average, each student saw and dictated 32 patient encounters but omitted five to six from their logs. There were no significant differences between the 10 honors and 69 non-honors students in the proportion of patients omitted from logbooks. CONCLUSIONS: Medical students underreport patient encounters in clerkship logbooks. Keeping a record of the patients dictated by medical students was helpful in determining the accuracy of students' logbooks.     

Attitudes of medical students to HIV and AIDS

OBJECTIVE--To assess the knowledge and attitudes of medical students to HIV/AIDS and whether attitudes correlate with knowledge and clinical experience. To determine if students felt adequately prepared to deal with medical and psychological aspects of HIV/AIDS. SUBJECTS AND METHODS--The subjects consisted of 190 London and 99 Cambridge medical students at the end of their genitourinary medicine attachment, plus 230 Cambridge medical students at the end of their second pre-clinical year. Between March 1991 and February 1992 all were asked to complete an anonymous questionnaire, covering factual knowledge and attitudes towards HIV/AIDS. MAIN RESULTS--Cambridge genitourinary medicine students, despite spending less time studying HIV infection than their London counterparts gave more correct answers to the factual questions, although this difference did not reach significance (52.4% vs. 47.5%, p = 0.14). One third of students believed that many health care workers were at high risk of acquiring HIV at work and one fifth thought doctors should have the right to refuse to treat people with HIV. Fourteen percent of Cambridge genitourinary medicine students indicated that most British people with HIV have only themselves to blame, by comparison with 4% of London students (p = 0.003). Thirty-nine per cent of Cambridge genitourinary medicine students expressed reluctance to care for someone with AIDS by comparison with 10% of London students (p = 0.0001). CONCLUSIONS--It is important that medical educators convey accurate information about HIV, including the actual risks posed by occupational exposure and try to ensure that medical students spend sufficient time seeing patients with HIV/AIDS during their training.     

The relationship between preceptor expectations and student performance on 2 pediatric objective structured clinical examination stations

BACKGROUND: We designed 2 pediatric objective structured clinical examination stations, 1 anemia case associated with lead exposure and 1 failure-to-gain-weight case associated with extended breast-feeding, to evaluate third-year medical students who had studied in pediatric community preceptors' offices as part of a 12-week multidisciplinary ambulatory clerkship rotation. OBJECTIVE: To examine the relationship between preceptor expectations and student performance on these 2 objective structured clinical examination stations. METHODS: To elicit community preceptors' expectations of student performance, we constructed a 46-item survey replicating checklists filled out by simulated patients evaluating student performance on the objective structured clinical examination stations. The percentage agreement among preceptors for each checklist item as well as the percentage agreement between preceptor responses and student responses on each checklist item were calculated. A summary score of preceptor responses across all checklist items and a summary score for student responses across all checklist items on each station were calculated. The correlation coefficients between preceptor and student summary scores were then examined. RESULTS: Fifty-nine preceptor surveys were mailed and 38 were returned (64% response rate). Data were usable from 37 surveys. Eighty-nine percent (33 of 37)of the preceptors agreed that a third-year clerkship student should have the knowledge to care for the patient with anemia and 92% (34 of 37)of the preceptors agreed similarly for the growth-delay case. Agreement among preceptors on individual checklist items varied widely for both cases. Fifty-seven students studied at the anemia station and 34 students studied at the growth-delay station. The mean+/-SD agreement across the 26 items on the anemia case between preceptor responses and student responses was 62%+/-23% and, for the 21 items on the growth-delay case, 60%+/-17%. The mean+/-SD preceptor summary score for the anemia case was 17.4+/-3.8 (maximum, 26) and 16.0+/-3.6 (maximum, 21) for the growth-delay case. The mean student score on the anemia case was 15.5+/-3.7 (maximum, 26) and, for the growth-delay case, 10.0+/-4.5 (maximum, 21). The Pearson correlation coefficient between the preceptor and student scores on the anemia case was 0.19 (P=.15), and for the growth-delay case,-0.41 (P=.06). CONCLUSIONS: These data suggest community preceptors agree on topic areas in which students should be clinically competent. There was, however, considerable variation in agreement among preceptors about what preceptors believe students should be able to do and how the students actually perform. The overall percentage agreement between preceptor expectations and student performance appears to be no better than chance.     

The Women's Health Curriculum by a problem-based learning method for medical students at the University of California, San Francisco

OBJECTIVES: Our objectives were to (1) expand and strengthen the women's health curriculum at the University of California, San Francisco, and (2) evaluate the responses of both medical students and faculty to this curriculum. STUDY DESIGN: A written evaluation of the curriculum in women's health was completed by both students and faculty. Variables studied included mean scores of cases, the overall course score, and the preferences of medical students for faculty specialty in teaching the small groups. RESULTS: The overall course evaluation score was 7.81 (range 1 to 10). For those students who had both faculty from internal medicine or family medicine and obstetrics and gynecology, there was a strong preference that obstetrician-gynecologists teach the majority of the cases. CONCLUSIONS: The new case-based curriculum in women's health was enthusiastically received by both medical students and faculty.
