Creation, evaluation, and continuing assurance of excellence of the certified surgical specialist.

A position paper on the subject of certified surgical specialists was published in 1966 under the direction of Professor Charles Wells of Liverpool, England. President John Terblanche of the International Federation of Surgical Colleges brought together leaders in surgical education from four nations (Australia, Japan, South Africa, United States) to update current "state-of-the art" views. Presentations were made at the 38th Congress of the International Society of Surgery, August 18, 1999 in Vienna, Austria. After careful review of the four presentations, it was clear that surgeons all over the world have made great improvements in the many facets of surgical education. Yet the advances remain spotty, with gaps noted when viewed from an international perspective.

Problem-based learning: an effective educational method for a surgery clerkship.

Problem-based learning (PBL) has been implemented during the clinical years in a few medical schools. The purpose of this study is to determine whether PBL provides a better education than traditional methods. Students in the first and third rotations (n = 42) went through the traditional clerkship, which utilized Socratic teaching (SI), while students in the second and fourth rotations (n = 36) were taught by the PBL method. Two performance measures were used to assess clerkship effectiveness. One was a modified essay examination (MEE) administered as part of the departmental evaluation. The other was the NBME-II exam and its surgery subsection NBME-II-S. The MEE was designed to measure six dimensions of the problem-solving process. The NBME-II was utilized to measure knowledge. Unpaired t tests were used to identify statistically significant group differences. The PBL group performed significantly better on two MEE dimensions: (1) differential diagnosis formation (PBL, 92.5 +/- 0.8; SI, 89.1 +/- 0.5; P < 0.01) and (2) interpretation of clinical data (PBL, 93.3 +/- 0.6; SI, 91.6 +/- 0.4; P < 0.03). A third dimension, ordering appropriate lab and diagnostic studies, approached significance (P = 0.057), and the PBL group performed better. On the NBME-II there was not a significant difference between the two groups. However, the trend (P = 0.059) was for the PBL group to score higher on the NBME-II-S (PBL mean: 502 +/- 15; SI mean: 468 +/- 12). When overall achievement was controlled for, the PBL group performed significantly better than the SI group (P = 0.046) on the NBME-II-S.(ABSTRACT TRUNCATED AT 250 WORDS)

Undergraduate surgical education for the twenty-first century.

This article addresses the problems associated with current undergraduate surgical education and discusses the requirements necessary for its improvement during the third and fourth years of medical school. It asserts that, coincident with the emphasis on faculty research and publication and expanded resident patient care duties, teaching, particularly medical student teaching, has assumed a very low priority. Third-year medical students are attached to surgical teams, where their education is haphazard and disorganized. Furthermore, because any teaching that occurs is teacher oriented rather than student centered, knowledge is accumulated passively and is not well retained. Traditional evaluation using shelf multiple choice examinations and ward ratings by residents and faculty may provide inaccurate assessments of the students' performance. The undergraduate surgical education program should be directed by a faculty member who has been grounded in educational techniques and research and supported by a department chairman committed to bettering the program. In the clerkship, medical students should be assigned to faculty rather than to services and should be presented problems that require solution. Students also should be provided with the resources to solve the problems and should be given sufficient time to solve them. Some operating room experience and bedside teaching should occur during the clerkship. A variety of evaluation and testing methods based on the learning objectives of the clerkship should be used. Third-year students should not be promoted until they have demonstrated their acquisition of appropriate knowledge and skills.(ABSTRACT TRUNCATED AT 250 WORDS)

The controllable lifestyle factor and students' attitudes about specialty selection.

Questionnaires were distributed to 346 fourth-year students in nine medical schools. The students were asked to state their selected specialty and to rank the importance that each of 25 influences, listed as questionnaire items, had had in making their choice of specialty. Factor analysis showed that particular items were significantly associated with particular factors. The first factor emphasized perceived lifestyle (items in this category gave importance to remuneration, personal time, and prestige); the second factor emphasized cerebral activities and a practice orientation; and the third factor stressed altruistic values and attitudes. The authors classified the selected specialties into three groups: those characterized as having a non-controllable lifestyle (NCL), those with a controllable lifestyle (CL), and surgery. (CL specialties were defined as those that allow the physician to control the number of hours devoted to practicing the specialty.) Data were analyzed using factor analysis, and analysis of variance, and the Scheffé method. Analysis indicated that the perceived lifestyle factor was most closely associated with the responses of those students choosing CL specialties. Furthermore, this factor received the highest total loading of the three factors from all the students, thus indicating the level of interest in lifestyle factors. Responses to items that defined the cerebral and practice factor were highest from the group of students choosing CL specialties and lowest from the group choosing NCL specialties. The NCL students scored highest in the altruism factor and the CL students scored the lowest. The surgery and NCL groups were similar in attitude patterns, and both were substantially different in attitude patterns from those of the CL groups.(ABSTRACT TRUNCATED AT 250 WORDS)
