Is it possible to assess the "ethics" of medical school applicants? (65/2287)

Questions surrounding the assessment of medical school applicants' morality are difficult but they are nevertheless important for medical schools to consider. It is probably inappropriate to attempt to assess medical school applicants' ethical knowledge, moral reasoning, or beliefs about ethical issues as these all may be developed during the process of education. Attitudes towards ethical issues and ethical sensitivity, however, might be tested in the context of testing for personality attributes. Before any "ethics" testing is introduced as part of screening for admission to medical school it would require validation. We suggest a number of ways in which this might be achieved.  (+info)

The timing and stability of choice of medical specialty among Malaysian doctors. (66/2287)

A total of 356 doctors responded to a survey on the timing and stability of choice of medical specialty. The majority of doctors made their final decision while working as a medical officer. One hundred (48.5%) of the doctors had made an earlier choice as medical students, 63 (30.6%) during their internship and 43 (20.9%) made their final choice while they were medical officers. Working experience in the specialty was the most important factor in determining final choice of specialty. Advice from consultants/seniors, better financial prospects and parental influence were more important for the male doctors while marriage and family considerations were more important for the female doctors in making their final choice.  (+info)

Introducing a reward system in assessment in histology: a comment on the learning strategies it might engender. (67/2287)

BACKGROUND: Assessment, as an inextricable component of the curriculum, is an important factor influencing student approaches to learning. If assessment is to drive learning, then it must assess the desired outcomes. In an effort to alleviate some of the anxiety associated with a traditional discipline-based second year of medical studies, a bonus system was introduced into the Histology assessment. Students obtaining a year mark of 70% were rewarded with full marks for some tests, resulting in many requiring only a few percentage points in the final examination to pass Histology. METHODS: In order to ascertain whether this bonus system might be impacting positively on student learning, thirty-two second year medical students (non-randomly selected, representing four academic groups based on their mid-year results) were interviewed in 1997 and, in 1999, the entire second year class completed a questionnaire (n = 189). Both groups were asked their opinions of the bonus system. RESULTS: Both groups overwhelming voted in favour of the bonus system, despite less than 45% of students failing to achieve it. Students commented that it relieved some of the stress of the year-end examinations, and was generally motivating with regard to their work commitment. CONCLUSIONS: Being satisfied with how and what we assess in Histology, we are of the opinion that this reward system may contribute to engendering appropriate learning approaches (i.e. for understanding) in students. As a result of its apparent positive influence on learning and attitudes towards learning, this bonus system will continue to operate until the traditional programme is phased out. It is hoped that other educators, believing that their assessment is a reflection of the intended outcomes, might recognise merit in rewarding students for consistent achievement.  (+info)

Exhibits facilitate histology laboratory instruction: student evaluation of learning resources. (68/2287)

Some professional schools have replaced microscopes for histology laboratory instruction with printed and electronic media. It is recognized that these media cannot replace experience with the microscope and that there is a cognitive dissonance of completely replacing microscope study. In addition, students believe that their time is not optimally used in the traditional histology laboratory. Therefore, at Loma Linda University, nine weekly microscope exhibits consisting of 10-15 slides each were prepared. For each exhibited slide, a one page "atlas" is provided, consisting of labeled low- and high-power color micrographs taken from that slide and an informative legend. By referring to the atlas, the student can easily identify the exact field and the labeled features with little help from an instructor. A live or taped video demonstration of the microscope exhibit is available on the first day of the exhibit. During the eighth week of the quarter, students were asked to evaluate the various learning resources available to them. No resource was valued significantly more than the microscope exhibits, but the video demonstrations were valued significantly more than the printed black and white atlas or the color atlas on CD. These exhibits have been used for 2 years to instruct a class of 90 dental students. Advantages are (1) students' time is used efficiently, (2) only one slide set and a fourth as many microscopes need be maintained compared with a traditional laboratory, and (3) one-of-a-kind slides derived from research activities provide for high impact learning.  (+info)

Detection of meningococcal carriage by culture and PCR of throat swabs and mouth gargles. (69/2287)

The standard method for detecting meningococcal carriage is culture of throat swabs on selective media, but the levels of carriage determined depend heavily on the skills of the individuals taking the swab and interpreting the cultures. This study aimed to determine the most sensitive detection method for meningococcal carriage. Throat swabs and saline mouth gargles, obtained from 89 university students, were processed in parallel by conventional culture and TaqMan ctrA PCR. Carriage of meningococci, as detected by the combined methods, was 20%. The sensitivities of throat swab culture, throat swab PCR, gargle culture, and gargle PCR were 72, 56, 56, and 50%, respectively, and the probabilities that these techniques would correctly identify the absence of carriage (negative predictive value [NPV]) were 93.4, 89.9, 89.9, and 88.8%. Culturing both throat swabs and gargles increased the NPV to 98.6%. The further addition of throat swab PCR increased this to 100%. Testing gargles by both culture and PCR was as sensitive as testing throat swabs by both methods, suggesting that gargles may be a suitable alternative for large-scale screening studies when throat swabs are difficult to obtain, although they required more lengthy laboratory processing. PCR was a useful adjunct to culture for detecting nasopharyngeal carriage, but it failed to detect some nongroupable strains. For maximum sensitivity, a combination of techniques was required. This study indicates the confidence with which health care professionals involved in meningococcal screening can regard laboratory results.  (+info)

Patients' attitudes towards the presence of medical students in family practice consultations. (70/2287)

BACKGROUND: Patients' consent to being part of medical education is often taken for granted, both in primary and secondary care. Formal consent procedures are not used routinely during teaching and patients are not always aware of teaching activities. OBJECTIVE: To investigate patients' attitudes and expectations on issues of consent regarding participation in teaching in general practice, and the influence of a student's presence on the consultation. METHODS: The study took place in 46 teaching practices during the sixth year clinical internship in family medicine. Patients completed questionnaires at the end of 10 consecutive eligible consultations. The questionnaire contained data on the willingness to participate in teaching, the preferred consent procedure and the effects of the student's presence. The doctors were asked to estimate the sociodemographic level in their clinic area. RESULTS: A total of 375 questionnaires were returned; the response rate was not affected by the clinic's sociodemographic level. Overall, 67% of the patients had come into contact with students in the past; 3.2% of the participants objected to the presence of a student during the consultation; 15% would insist on advance notification of the presence of a student, and another 13.9% would request it; 4% stated that the presence of students had a detrimental influence on the physical examination and history; and 33.6% would refuse to be examined by a student without the doctor's presence. CONCLUSION: Most patients agreed to have a student present during the consultation; some would like prior notification; a minority refused the student's presence. A large minority would refuse to be examined without the tutor's presence. Our findings need to be taken into account when planning clinical clerkships.  (+info)

Electrocardiogram and rhythm strip interpretation by final year medical students. (71/2287)

The pre-registration house officers (PRHO) is often called upon to interpret electrocardiograms ECG. We invited final-year medical students who had successfully completed their written final examinations, to interpret three rhythm-strip tracings, and three 12-lead ECG tracings. The rhythm-strips were of ventricular fibrillation (VF), ventricular tachycardia (VT), and complete heart block. Of the three 12-lead ECG tracings, one was an inferior myocardial infarction (MI), one was atrial fibrillation (AF), and one showed no abnormality. Forty-six medical students attended. Of these, 50% had received no formal training in ECG interpretation, although 89% had tried to learn ECG interpretation from books. Only 9% felt confident in their interpretation of ECG tracings. Of the rhythm-strips, 100% correctly identified VF, 96% recognised VT, and 67% identified complete heart block. Of the 12-lead ECG tracings, 61 % recognised the MI, 54% recognised AF, and only 46% successfully identified the normal ECG as such. The group were significantly worse at 12-lead ECG interpretation compared to rhythm-strips (p<0.01). The members of the group who had received formal training in ECG interpretation were significantly better at interpreting both rhythm-strips and 12-lead ECG tracings (p<0.05). It would appear that formal ECG training as an undergraduate improves PRHO interpretation of ECG tracings, and the PRHO should not interpret 12-lead ECG tracings without consulting more senior medical staff.  (+info)

Small group teaching: clinical correlation with a human patient simulator. (72/2287)

The popularity of the problem-based learning paradigm has stimulated new interest in small group, interactive teaching techniques. Medical educators of physiology have long recognized the value of such methods, using animal-based laboratories to demonstrate difficult physiological principles. Due to ethical and other concerns, a replacement of this teaching tool has been sought. Here, the author describes the use of a full-scale human patient simulator for such a workshop. The simulator is a life-size mannequin with physical findings (palpable pulses, breath/heart sounds, blinking eyes, etc.) and sophisticated mechanical and software models of the cardiovascular and pulmonary systems. It can be connected to standard physiological monitors to reproduce a realistic clinical environment. In groups of 10, first-year medical students explore Starling's law of the heart, the physiology of the Valsalva maneuver, and the function of the baroreceptor in a clinically realistic context using the simulator. With the use of a novel pre-/postworkshop assessment instrument that included student confidence in their answers, student confidence improved for all questions and survey items following the simulator session (P < 0.0001). The students give these laboratory exercises uniformly superior evaluations with > 85% of the students rating the workshop "very good" or "excellent".  (+info)
