Problem-based learning and medical student radiology teaching

The present study describes some practical advantages and disadvantages of problem-based learning (PBL), and makes suggestions to improve PBL radiology teaching of medical students.     

Medical student perceptions of diagnostic radiology. Influence of a senior radiology elective

To assess the impact of a four-week elective on medical student perceptions of diagnostic radiology, we gave questionnaires to 96 senior students on the first and last days of the rotation. Eighty-five anonymous entrance responses and 73 exit responses were obtained during a 13-month interval. Compared with other clinical specialties, the students viewed radiology as third, behind surgery and medicine, in terms of required breadth of knowledge, skill, training, and "glamour." Radiology was also perceived to have the lightest workload with the exception of psychiatry. Responses did not significantly change after completion of the elective. Perceived advantages and disadvantages of radiology were studied in detail in a subset of students. Exit responses indicated that the elective promoted favorable perceptions of radiology but did not change the relative rankings of the various specialties. It appears that at our institution basic attitudes concerning radiology are formed prior to the senior radiology elective and are affected only moderately during the elective.     

Medical student attitudes toward radiology. A multi-institutional survey

A questionnaire was administered to 238 students at four institutions before and after a radiology clerkship to evaluate student attitudes regarding radiology as a career, radiologist expertise, and clerkship expectations. There was no statistically significant difference among the clerkships, although they varied in types of experience, geographic location, and size. After the clerkship, the students agreed more strongly that the radiologist should be involved in patient workup, screening of requests, interpretation of emergency room films, and consultations. A significant change in attitude could be identified after the four-week experience, indicating a desire for the radiologist to have a more active role as imaging consultant.     

Prioritization of radiotherapy in Australia and New Zealand

The purpose of this study was to document how radiation oncology departments in Australia and New Zealand manage extended waiting lists by prioritizing patients for radiotherapy and how these centres define the "waiting time". A literature search on strategies for management of waiting lists in radiotherapy, both locally and internationally, was performed. A collaborative survey of all the radiotherapy departments in Australia and New Zealand was then undertaken. Of the 32 centres surveyed around Australia and New Zealand, 25 (77%) responded. There was considerable variation in the definitions used for "waiting times". Eleven of the 25 centres had formally documented protocols. New Zealand has a national policy for prioritization of patients for radiotherapy. Six centres had verbal protocols. Four centres had no significant waiting times and did not require a protocol for prioritization. One centre prioritized according to clinician discretion, two centres used a first-come, first-served basis. One centre replied but their protocol was missing. The variation in the definition of waiting time reduces its usefulness as an indirect measure of resources and as a method of comparing centres. There is also wide variation in the management of waiting lists, particularly in the prioritization schedules used by different centres. The major factor contributing to waiting lists at present is a shortage of radiation oncology staff, particularly radiation therapists. The implementation of standardized protocols for prioritizing patients may be useful in helping to manage scarce resources not withstanding the need to increase the resource base. However, the existence of such protocols should not give legitimacy to undue delays in commencing radiation treatment.     

Profile of medical student teaching in radiology: teaching methods, staff participation, and rewards

RATIONALE AND OBJECTIVES: The purpose of this study was to collect demographic information about radiology departments and rewards for teaching activities, as well as the impact of new digital imaging methods on teaching. MATERIALS AND METHODS: Two surveys were conducted of directors of medical school clerkships in radiology. The initial survey focused on numbers of staff and students, courses taught, and perception of rewards for teaching. The follow-up survey more specifically addressed teaching methods. RESULTS: Sixty-nine (50%) of the initial surveys sent to 139 departments and 46 (39% of a total of 119) of the follow-up surveys were returned. Clerkship directors spent an average of 9 hours per week teaching and performing administrative tasks, with most given no additional time off. Eighty-four percent of departments provide either no or insignificant rewards for teaching. Many departments have integrated the use of computers in teaching, and most have computers that students use during the radiology course. At the same time, digital imaging and picture archiving and communication systems (PACS) are used, or will be used within 1 year, in most departments. CONCLUSION: Clerkship directors receive little compensation in terms of time and rewards for medical student teaching. Teaching methods are evolving in response to the increasing use of computers, digital imaging, and PACS for at least part of the workload in most radiology departments.     

Medical docimology in radiology

The authors report the experience of computerized integrated didactics on trial at the Institute of Radiology of the University of Catania. Students majoring in Medicine undergo a propaedeutic written test, consisting in a number of multiple choice questions, before proceeding to the oral examination in radiology. The procedures preceding the test and those following it are accomplished with the aid of a computer. The authors discuss the docimological motivations, the specifications of the system and the results obtained after a trial period.     

Creating and enhancing radiology student interest groups

Student interest groups are an important forum in which medical students learn about and develop interest in different medical specialties. To attract top students to radiology and promote understanding and appreciation of radiology among future physicians, it is important that radiology educators help to develop and sustain such groups at their institutions. This article reviews key considerations in creating and enhancing a radiology student interest group.     

Sequential audits of unacceptable delays in radiation therapy in Australia and New Zealand

Delays in accessing radiation treatment are of concern in Australia and New Zealand, both in terms of the proportion of patients who are actually able to access care, and in the timeliness of starting treatment. For those who are able to access treatment, one in three patients experience an unacceptable delay in starting treatment, and only one in four patients starts radiotherapy within standard good practice times. During the year 2002, more than 15 000 Australians who potentially could have benefited from radiotherapy, did not receive this treatment. For those who were able to access radiotherapy treatment, worsening delays were experienced in Australia, with greater than 40% of patients receiving curative treatment, 30% receiving palliative treatment, and 56% receiving emergency treatment starting outside of standard good practice times. Delays of up to 151 days were experienced in Australia. In Australia, delays in implementing recommendations to improve the infrastructure are resulting in a declining service for cancer patients. In New Zealand, the situation, in general, is improving, although there needs to be an ongoing commitment to grow the service according to the population needs. Urgent implementation of strategic planning is required.     

The value of good medical student teaching: increasing the number of radiology residency applicants

RATIONALE AND OBJECTIVES: The authors attempted to define the value of good medical student teaching to the profession of radiology by examining the effect of radiology course improvements on the number of 4th-year students applying to radiology residencies. MATERIALS AND METHODS: Course evaluation and residency application data were obtained from six consecutive classes of 4th-year medical students at the study institution, and these data were compared with national data. RESULTS: Between 1995 and 2000, the number of 4th-year U.S. medical students applying to radiology increased 1.6 times. At the study institution, that number increased 4.5 times, a statistically significant difference (P = .020, chi2 test). Student survey data indicate that this increase reflects a general increase in the quality of radiology teaching in the study institution and specific changes in a required 2nd-year medical school course. CONCLUSION: These results strongly suggest that good medical student teaching pays important dividends, not only to the departments that provide it but also to the profession of radiology as a whole. Exposing students to good radiology teaching early in their medical school careers is especially important. Radiology departments that provide outstanding medical student education should be studied to help develop a model of educational best practices.     

Projected requirements for radiation oncologists and trainees in Australia and New Zealand to 2007

Workloads in radiation oncology facilities in Australia and New Zealand have been increasing steadily for many years and it is anticipated that this trend will continue. In the present paper the projected number of radiation oncologists required to meet this demand to the year 2007 are estimated, along with the number of trainees required. The estimates are based on data from regular surveys by the Royal Australian and New Zealand College of Radiologists (RANZCR) for the years 1988-97 (inclusive). From these surveys profiles of numbers, age and gender of specialists and trainees are documented together with increases from the training programme and losses from retirement. It is concluded that if the current trainee numbers are increased by 12 in Australia and two in New Zealand, there will be approximately 10 radiation oncologists per million of population by the year 2007. This number is considered appropriate considering the anticipated increase in demands and complexity of treatment. Because projections too far forward are unreliable, careful monitoring of progress is essential to obtain the appropriate balance between requirement and supply. Comparisons are made with other estimates of needs including the 1998 Australian Medical Workforce Advisory Committee (AMWAC) Report and the New Zealand Clinical Agency Workforce Project Report in 1997.
