Journal publications in radiologic education: a review of the literature, 1987-1997.

RATIONALE AND OBJECTIVES: This study was designed to analyze articles on radiologic education quantitatively and qualitatively, comparing those published in 1987-1997 with those published in 1966-1986. MATERIALS AND METHODS: An initial literature search used four major databases to identify and retrieve articles related to radiologic education. Additional articles were identified through manual cross-checking of references from the original articles. All articles were reviewed by two radiologists as to type of article (editorial, expository, survey, correlational, or experimental, including preexperimental, quasi-experimental, or true experimental), statistics used (inferential or descriptive), educational emphasis (medical student, resident, postgraduate, or other), and topic of article (philosophical or political, technology, program evaluation, program description, examinations, or career decisions). Interrater agreement was estimated by means of the kappa statistic. A chi2 test for independence was used to assess whether the relative distribution of articles was similar for the two periods. RESULTS: More articles per year were published in 1987-1997 (n = 12.6, P < .01) compared with 1966-1986 (n = 9.2). Articles pertinent to radiologic resident education predominated (50.7% vs 29.9% in the prior study, P < .01). In both periods, most articles were expository (37.7% vs 49.5%), and the most common topic was program description (34% vs 35%). Editorials decreased from 35.5% to 18.1%. Experimental studies accounted for 12.3%, increased from 8.7%. The fastest-growing topic of study was technology (30.4% vs 17.5%, P < .01). CONCLUSION: The increased number of articles addressing radiologic education is encouraging. Although the percentage of experimental studies increased slightly in this period, there is still little empirical research in radiologic education.

Career advancement of men and women in academic radiology: is the playing field level?

RATIONALE AND OBJECTIVES: The authors' purposes were to determine if there are gender differences in the speed of promotion and/or academic productivity in academic radiology and if this situation had changed since a previous study was performed in 1987. MATERIALS AND METHODS: Surveys were distributed to faculty members of academic radiology departments in May 1997. A total of 707 surveys were analyzed according to gender for time at rank for assistant and associate professor levels, in relation to publication rate, grant funding rate, and distribution of professional time. RESULTS: There was no difference between genders in the time at assistant professor rank. Among all current professors, women had been associate professors longer than men, but there was no difference between genders for those who had been in academic radiology for less than 15 years. There was no gender difference at any rank in the rate of publishing original articles. There was no difference in funding rates, although men had more total grant support. Male associate professors reported spending more time in administration and slightly more time in total hours at work than did their female colleagues, and male professors spent slightly more time teaching residents. Otherwise, there is no difference in how men and women at any rank spend their professional time. There are, however, lower percentages of women in tenured positions and in the uppermost levels of departmental administration. CONCLUSION: The time at rank for men and women and their rate of publication appear to have equalized. Women still are underrepresented at the uppermost levels of departmental administration, however, and are less likely than men to hold tenured positions.

Interinstitutional study to compare the effectiveness of a radiology-anatomy module of instruction.

RATIONALE AND OBJECTIVES: The purpose of this study was to validate the effectiveness of a proven radiology-anatomy instructional module during I st-year gross anatomy courses at Emory University College of Medicine and the University of Iowa College of Medicine. MATERIALS AND METHODS: This prospective study involved 108 Emory students and 177 Iowa students. The instructional content was the same at both institutions. Each student was randomly assigned into one of three groups at each institution, and each group received a unique, randomized, five-item pretest. All students were posttested as part of their gross anatomy laboratory examination, and the posttests consisted of all 15 items used in the three five-item pretests. RESULTS: No statistically significant pretest effects were demonstrated by t tests. Posttest performances across items ranged from 73% to 96% correct for Emory students and 67% to 98% for Iowa students. Performance levels on the posttests were significantly higher than on pretests, and few significant differences were found in the performance of the two populations. CONCLUSION: The radiology-anatomy instructional module integrated into the gross anatomy courses for 1st-year Emory University and University of Iowa students was not instructor or institution dependent.

The road to success: factors affecting the speed of promotion of academic radiologists.

RATIONALE AND OBJECTIVES: The authors' purpose was to determine the factors influencing the speed of promotion of academic radiologists. MATERIALS AND METHODS: Three hundred forty-three surveys from faculty members of academic radiology departments with continuous academic careers were analyzed for time in rank at assistant and associate professor levels in relation to publication rate, grant funding rate, and distribution of professional time. Individuals promoted faster than the median time (6 years for assistant professors, 5 years for associate professors) were considered "fast track" and were compared with the remainder of the group. RESULTS: At the assistant professor level, fast track individuals had significantly higher rates of total publications and original articles than did others. At the level of associate professor, fast track individuals had significantly faster rates of publication of original articles, but no significant difference existed in total publication rate. No significant difference was found in the rate of founding of fast track individuals and others. Those with funding were not more likely to be on a fast track than those without funding. Fast track individuals spent significantly more time in administration at the assistant professor level than did other faculty, but no other significant differences were discovered in time distribution at the assistant or associate professor level. CONCLUSIONS: The rate of publishing original articles at the assistant and associate professor levels and the rate of overall publication at the assistant professor level were the most important parameters in predicting speed of promotion.

Medical students' attitudes toward radiology: comparison of matriculating and graduating students.

RATIONALE AND OBJECTIVES: To determine graduating medical students' perceptions of radiology and to document changes in their perceptions since they entered medical school. MATERIALS AND METHODS: A survey questionnaire was distributed to 213 graduating students. Questions were similar to those answered by the same group of students as they entered medical school nearly 4 years earlier. RESULTS: The survey was anonymously completed by 140 students. Seventy percent of students changed their choice of medical specialty since entering medical school. Factors with a major or important influence on specialty choice included intellectual excitement (96%), high patient contact (86%), opportunity for a good family life (72%), and regular hours (57%). Radiology was perceived to be a well-paid (89%), "high-tech" (86%) specialty with a healthy lifestyle (82%), regular hours (99%), and good family life (92%), but it was not perceived to offer high patient contact (1%) and was intellectually exciting to only 33% of students. This perception was unchanged from freshman year. CONCLUSIONS: This 4-year longitudinal study of a medical student class documents surprisingly little change in the perception of radiology throughout medical school. High patient contact and intellectual excitement, both factors of major or important influence on specialty choice, were thought to be lacking in radiology.

Graduates speak: the employment experience of 1995 graduates of diagnostic radiology and radiation oncology training programs.

PURPOSE: To determine the initial employment experience of 1995 graduates of radiology programs. MATERIALS AND METHODS: A questionnaire was mailed to all graduates of radiation oncology programs and to a stratified, random sample of 600 graduates of diagnostic radiology programs. The final response rate was 66%. RESULTS: After graduation, 4%-10% of graduates worked for a period as locum tenens, worked in a job unrelated to radiology, or were unemployed. Immediate postgraduation unemployment was 2%-5%; 7-12 months later, it was less than 0.5%. Median actual salary was approximately equal to median expected salary. Radiation oncology fellowship graduates often had poorer outcomes. Almost half of the graduates with posttraining employment had a job with at least one characteristic regarded as unfavorable by some commentators (most commonly, undesirable location or no opportunity to become a partner), and at least one-fifth had and disliked such a characteristic. Geographic constraints, including the need to find employment for a spouse or companion, did not adversely affect employment outcome. CONCLUSION: Eventual unemployment was low, and starting salaries have not collapsed. Generally, the implications of job characteristics are best assessed by monitoring trends, but the prevalence of non-partnership track employment may well have increased.

Extracorporeal membrane oxygenation in adults: radiographic findings and correlation of lung opacity with patient mortality.

PURPOSE: To describe the radiographic appearance of extracorporeal membrane oxygenation (ECMO) in adults and to correlate lung opacity with physiologic parameters and mortality. MATERIALS AND METHODS: Chest radiographs of 50 adults treated with ECMO were reviewed; pre-ECMO radiographs were available in 35 patients. Lung opacity was assigned a score of 0-4. Complications of ECMO seen at chest radiography were recorded. RESULTS: The lung opacity scores of the first post-ECMO radiographs were higher than those of the pre-ECMO radiographs in 17 of 35 patients (P = .0005). Maximum opacity score was significantly lower for patients who survived compared with those who died (P = .001). Twelve of 14 patients (86%) with a maximum opacity score of 4 died, compared with eight of 29 patients (28%) with a maximum score of 3. Sixteen of 26 patients (61%) with evidence of baro-trauma died, compared with six of 24 patients (25%) without pneumothorax (P = .02). Four patients developed hemothorax. CONCLUSION: Lung opacity increases immediately after initiation of ECMO. Increased opacity corresponds to decreased pulmonary function, and severe opacity correlates strongly with mortality.

First-year medical students' attitudes toward radiology.

To explore the perspectives of entering medical students, a questionnaire was completed anonymously by 171 students in September of their first year of medical school. The authors investigated their attitudes toward radiology relative to other specialties and their perspective concerning which factors would influence their eventual choice of a specialty. Upon entering medical school, 33.3% of the students indicated that they had chosen a specialty, and 7.4% of these students had selected radiology. Radiology was perceived as a well-paid specialty with a pleasant lifestyle. These are factors that were perceived as very important regarding influence on eventual choice of specialty. However, radiology was believed to have an undesirably low level of patient contact and was perceived as not being intellectually exciting. We plan to follow this group of students prospectively through medical school to see whether their attitudes change toward radiology as a career.

Diagnostic usefulness of post-void film in intravenous urogram.

A survey was sent to urologists to assess their subjective evaluation of the post-void film in the intravenous urogram (IVU). Most of the urologists believed that the post-void film should be a routine part of all IVUs, particularly in men over forty years of age, and estimated that the film contributed useful information in 30 percent of cases. One hundred fifty IVUs were reviewed to assess the actual value of the post-void film in 119 different patients. In these patients, the postvoid film was seen to give unique information not available by history or films of the filled bladder in only 3 percent of the cases. Therefore, we conclude the post-void film should not be a routine part of every IVU, and should be obtained on an as-needed basis only.

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.

Impact of pre-radiology clinical years on resident performance.

In 1971, the American Board of Radiology dropped the requirement for at least one pre-radiology clinical year (PRCY) of training. However, requiring a clinical year for radiology residents remains a controversial issue. We reviewed 896 rotation evaluation forms involving 62 residents to see if a difference in performance could be detected between residents who entered training without or with at least one PRCY. Forty-five residents had no previous clinical training, whereas 17 had one or more PRCYs. No significant differences were detected in resident performance between non-PRCY and PRCY residents, nor were differences found by sex, age, presence of non-medical postgraduate degrees, or scores on the first part of the National Board of Medical Examiners. No study of PRCY versus non-PRCY residents can be adequately controlled; thus the failure to show a difference in performance must be interpreted with caution.
