Short-term impact of a laparoscopic "mini-residency" experience on postgraduate urologists' practice patterns.

BACKGROUND: To assist practicing urologists incorporate laparoscopic urology into their practice, a 5-day mini-residency (M-R) program with a mentor, preceptor, and proctor experience was established at the University of California, Irvine, and we report the initial results. STUDY DESIGN: Thirty-two urologists underwent laparoscopic ablative (n=17) or laparoscopic reconstructive (n=15) training, including inanimate model skills training, animal laboratory, and operating room observation. A questionnaire was mailed 1 to 15 months (mean, 8 months) after their M-R program, and responses were reviewed. RESULTS: A 100% response rate was achieved. The mean M-R participant age was 49 years (range 31 to 70 years). The majority of the participants (72%) had laparoscopic experience during residency training and had performed between 5 and 15 laparoscopic cases before attending the M-R program. Within 8 months after M-R, 26 participants (81%) were practicing laparoscopic surgery. Participants were performing laparoscopic radical nephrectomy (p=0.008), nephroureterectomy (p<0.0005), and pyeloplasty (p=0.008) at substantially higher rates after training. At the same time, fewer of the M-R participants were performing hand-assisted laparoscopic surgery after training (p=0.008) compared with before the M-R. Ninety-two percent of the participants indicated that they would recommend this training program to a colleague. CONCLUSIONS: A 5-day intensive laparoscopic ablative and reconstructive surgery course seems to encourage postgraduate urologists, already familiar with laparoscopy, to successfully expand the scope of their procedures to include more complex laparoscopic techniques such as nephrectomy, nephroureterectomy, and pyeloplasty into their clinical practice.

Competency in cardiac examination skills in medical students, trainees, physicians, and faculty: a multicenter study.

BACKGROUND: Cardiac examination is an essential aspect of the physical examination. Previous studies have shown poor diagnostic accuracy, but most used audio recordings, precluding correlation with visible observations. The training spectrum from medical students (MSs) to faculty has not been tested, to our knowledge. METHODS: A validated 50-question, computer-based test was used to assess 4 aspects of cardiac examination competency: (1) cardiac physiology knowledge, (2) auditory skills, (3) visual skills, and (4) integration of auditory and visual skills using computer graphic animations and virtual patient examinations (actual patients filmed at the bedside). We tested 860 participants: 318 MSs, 289 residents (225 internal medicine and 64 family medicine), 85 cardiology fellows, 131 physicians (50 full-time faculty, 12 volunteer clinical faculty, and 69 private practitioners), and 37 others. RESULTS: Mean scores improved from MS1-2 to MS3-4 (P = .003) but did not improve or differ significantly among MS3, MS4, internal medicine residents, family medicine residents, full-time faculty, volunteer clinical faculty, and private practitioners. Only cardiology fellows tested significantly better (P<.001), and they were the best in all 4 subcategories of competency, whereas MS1-2 were the worst in the auditory and visual subcategories. Participants demonstrated low specificity for systolic murmurs (0.35) and low sensitivity for diastolic murmurs (0.49). CONCLUSIONS: Cardiac examination skills do not improve after MS3 and may decline after years in practice, which has important implications for medical decision making, patient safety, cost-effective care, and continuing medical education. Improvement in cardiac examination competency will require training in simultaneous audio and visual examination in faculty and trainees.

Construct validity testing of a laparoscopic surgical simulator.

BACKGROUND: We present initial data on the construct, content, and face validity of the LAPMentor (Simbionix), virtual reality laparoscopic surgical simulator. STUDY DESIGN: Medical students (MS), residents and fellows (R/F), and experienced laparoscopic surgeons (ES), with < 30 laparoscopic cases per year (ES<30) and those with > 30 laparoscopic cases per year (ES>30), were tested on 9 basic skill tasks (SK) including manipulation of 0-degree and 30-degree cameras (SK1, SK2), eye-hand coordination (SK3), clipping (SK4), grasping and clipping (SK5), two-handed maneuvers (SK6), cutting (SK7), fulguration (SK8), and object-translocation (SK9). RESULTS: Mean MS (n=23), R/F (n=24), ES<30 (n=26), and ES>30 (n=30) ages were 26 years (range 21 to 32 years), 31 years (range 27 to 39 years), 49 years (range 31 to 70 years) and 47 years (range 34 to 69 years), respectively. In the lower level skill tasks (SK3, SK4, SK5, and SK6) the ES>30, ES<30, and R/F had similar scores, but were all substantially better than the MS scores. In the higher level skill tasks (SK7, SK8, and SK9), the ES>30 scores tended to be better than the R/F and ES<30, which were similar, and these, in turn, were markedly better than the MS. The ES>30 had notably higher SK8 scores than the R/F and ES<30, who had similar scores, and these had notably better scores than the MS. CONCLUSIONS: The noncamera skills (SK3 to 9) of the LAPMentor surgical simulator can distinguish between laparoscopically naive and ES. SK8 showed the highest level of construct validity, by accurately differentiating among the MS, R/F, ES<30 and ES>30.

Comparison of basic elements of human performance scores between urologists with various extents of experience.

BACKGROUND AND PURPOSE: An objective evaluation of innate ability and its ability to predict potential success as a surgical trainee is an appealing concept for the selection process of residency applications. The objective of this study was to evaluate whether basic elements of performance (BEP) could discriminate among resident applicants and urologists with various extents of surgical experience. SUBJECTS AND METHODS: One hundred forty-five participants were divided into four study groups: group A, 57 urology residency applicants to the 2002 and 2003 interview process; group B, 8 post-internship urology residents; group C, 19 urologists tested with BEP within 10 years of graduation from their residency training program; and group D, 61 urologists who had graduated from their residency training program more than 10 years prior to testing. The BEP measures consisted of 13 basic performance resources (BPR) including visual-information processing speed, visual-spatial immediate-recall capacity, and neuromotor channel capacity. RESULTS: The four study groups differed significantly in their mean age: group A=27.6 years, group B=29.1 years, group C=37.1 years, and group D=48.9 years (P<0.0005). There was essentially no significant difference between the groups with regard to immediate-recall memory, reaction time simple, or reaction time complicated. The younger participants (groups A and B) were faster than the older surgeons (groups C and D) (P<0.02). However, the older surgeons (groups C and D) were significantly more accurate than the younger groups (A and B) (P<0.0005). The only sex differences noted were in hand-grip strength and shoulder-strength scores, which were all higher in the men. CONCLUSIONS: There generally appears to be a lack of direct correlation between innate abilities and surgical experience. Urology resident applicants with no surgical experience and urology residents with limited surgical experience are faster but less accurate in innate skills testing than experienced practicing urologists.

Initial impact of a dedicated postgraduate laparoscopic mini-residency on clinical practice patterns.

BACKGROUND AND PURPOSE: Laparoscopic surgical techniques are difficult to master, especially for surgeons who did not receive this type of training during their residencies. We have established a 5-day mentor-preceptor- proctor-guided postgraduate "mini-residency" (M-R) experience in minimally invasive surgery. The initial results from the first 16 participants in the laparoscopic M-R modules are presented. PARTICIPANTS AND METHODS: On the first and the last day of the M-R, all participants underwent surgical skills testing using an open-surgery, standard laparoscopic, and robot-assisted laparoscopic format. A written examination was also administered on the last day. The influence of M-R on the participants' practice pattern was then assessed by a follow-up questionnaire survey 1 to 7 months after their attendance. RESULTS: Data from the first 16 participants were analyzed. Of note, the score was significantly improved for only one of the four tested laparoscopic skills (i.e., threading a suture through loops). Nonetheless, on the follow-up survey, of the 15 respondents, two laparoscopically naïve participants had performed laparoscopic nephrectomy, and of the eight participants who had prior renal-ablative laparoscopic experience, four had performed advanced reconstructive laparoscopic cases. CONCLUSIONS: A 5-day dedicated postgraduate M-R in laparoscopy appears to be helpful for urologists wishing to incorporate this surgical approach into their practices. The "take rate" among participants is initially at the 40% level, similar to what has been previously reported after a 1 to 2-day hands-on didactic laparoscopy course.

The on-line Clinical Teaching Perception Inventory: a "snapshot" of medical teachers.

BACKGROUND AND OBJECTIVES: Medical educators need practical and accurate instruments for evaluating clinical teaching. Our purpose was to develop norms for the Clinical Teaching Perception Inventory (CTPI) on a multidisciplinary group of North American faculty and resident teachers. METHODS: A no-cost, on-line inventory (www.residentteachers.com) measured participants' comfort with teaching. Respondents recruited through surveys and professional organizations completed two identical Q-sorts, ranking 28 descriptors first for "my ideal teacher" and then for "myself as a teacher." RESULTS: An international sample of 255 residents and 256 faculty members--including 143 respondents from family medicine--completed the on-line CTPI from April 2001 to March 2003. Resident and faculty teachers agreed on top descriptors for ideal clinical teachers: stimulating, encouraging, competent, communicates, and well-read. Resident teachers revealed larger discrepancies between "self" and "ideal" scores than faculty participants did. Many respondents wished to be more stimulating and well-read, highlighting perceived needs for teaching skills development. Between the subsamples of 143 family medicine teachers and 368 non-family medicine teachers, scores were virtually indistinguishable. CONCLUSIONS: A multidisciplinary sample of 511 faculty and resident teachers agreed on key characteristics of ideal clinical teachers. Generalist educators and others can use the on-line CTPI at no cost to assess their self-perceptions as clinical teachers.

The effect of a 13-hour curriculum to improve residents' teaching skills: a randomized trial.

BACKGROUND: Although resident physicians often teach, few trials have tested interventions to improve residents' teaching skills. A pilot trial in 2001-2002 found that 13 trained resident teachers taught better than did untrained control residents. OBJECTIVE: To determine whether a longitudinal residents-as-teachers curriculum improves residents' teaching skills. DESIGN: Randomized, controlled trial from May 2001 to February 2002 (pilot trial) and March 2002 to April 2003. SETTING: 4 generalist residencies affiliated with an urban academic medical center. PARTICIPANTS: 62 second-year residents: 23 in the 2001-2002 pilot trial and 39 more in 2002-2003; 27 of the 39 participants were medicine residents required to learn teaching skills. INTERVENTION: A 13-hour curriculum in which residents practiced teaching and received feedback during 1-hour small-group sessions taught twice monthly for 6 months. MEASUREMENTS: A 3.5-hour, 8-station, objective structured teaching examination that was enacted and rated by 50 medical students before and after the intervention. Two trained, blinded raters independently assessed each station (inter-rater reliability, 0.75). RESULTS: In the combined results for 2001-2003, the intervention group (n = 33) and control group (n = 29) were similar in sex, specialty, and academic performance. On a 1 to 5 Likert scale, intervention residents outscored controls on overall improvement score (post-test-pretest difference, 0.74 vs. 0.07; difference between intervention and control groups, 0.68 [95% CI, 0.55 to 0.81]; P < 0.001) by a magnitude of 2.8 standard deviations and on all 8 individual stations. The intervention residents improved 28.5% overall, whereas the scores of control residents did not increase significantly (2.7%). In 2002-2003, 19 intervention residents similarly outscored 19 controls (post-test-pretest difference, 0.83 vs. 0.14; difference between intervention and control groups, 0.69 [CI, 0.53 to 0.84]; P < 0.001). Twenty-seven medicine residents required to learn teaching skills achieved scores similar to those of volunteers. LIMITATIONS: The study was conducted at a single institution. No "real life" assessment with which to compare the results of the objective structured teaching examination was available. CONCLUSIONS: Generalist residents randomly assigned to receive a 13-hour longitudinal residents-as-teachers curriculum consistently showed improved teaching skills, as judged by medical student raters. Residents required to participate improved as much as volunteers did.

Evaluating a 'service elective' in clinical teaching for medical students.

Many medical students wish to begin developing clinical teaching skills before residency. Faculty at the University of California, Irvine developed a 60-hour, longitudinal 'service elective' in teaching skills, which 50 third-year and fourth-year students have completed since 2001. Students learned to enact and rate eight stations of an objective structured teaching examination (OSTE) for generalist resident physicians, broadening this practical training with in-class exercises. To evaluate the elective, structured, written questionnaires were administered. Participating students gave the elective a mean rating of 5.24 on a seven-point Likert-type scale, which fell between 'very good' (5) and 'excellent' (6). Narrative comments showed that students believed the elective--and in particular the OSTE training--prepared them well for teaching as residents.

A pilot randomized, controlled trial of a longitudinal residents-as-teachers curriculum.

PURPOSE: To determine whether a longitudinal residents-as-teachers curriculum improves generalist residents' teaching skills. METHOD: From May 2001 to February 2002, 23 second-year generalist residents in four residencies affiliated with the University of California, Irvine, College of Medicine, completed a randomized, controlled trial of a longitudinal residents-as-teachers program. Thirteen intervention residents underwent a 13-hour curriculum during one-hour noon conferences twice monthly for six months, practicing teaching skills and receiving checklist-guided feedback. In a 3.5-hour, eight-station objective structured teaching examination (OSTE) enacted and rated by 15 senior medical students before and after the curriculum, two trained, blinded raters independently assessed each station with detailed, case-specific rating scales (rating scale reliability = 0.96, inter-rater reliability = 0.78). RESULTS: The intervention and control groups were similar in academic performance, specialty distribution, and gender (chi(2) = 0.434, p =.81). On a five-point Likert scale (5 = best teaching skills), intervention and control residents showed similar mean pretest OSTE scores (2.83 vs. 2.88, p =.736). The intervention group improved their mean overall OSTE scores 22.3% (more than two standard deviations) from 2.83 (pretest) to 3.46 (post-test; p <.0005; 95% CI 0.53 to 0.72). Intervention residents also improved significantly on six of eight OSTE stations. Within the control group, no pretest-to-post-test change achieved statistical significance. Mann-Whitney and Wilcoxon signed-rank tests confirmed these results. CONCLUSIONS: Generalist residents randomly assigned to receive a 13-hour longitudinal residents-as-teachers curriculum consistently showed improved OSTE scores. Future research should clarify which aspects of residents-as-teachers curricula most effectively improve educational outcomes.

An international physician education program to support the recent introduction of family medicine in Egypt.

BACKGROUND AND OBJECTIVES: There are few reports of systematic international physician development programs to create family medicine as a new specialty in a developing nation. This paper describes the process and outcomes of a large-scale effort to initiate new family medicine training through the Egyptian Ministry of Health and Population (MOHP) using a 12-week US-based program at the University of California, Irvine (UCI). METHODS: Generalist physicians (n=134) with 1 year of internship training, currently working under the MOHP in Egypt, were competitively selected to participate in a training program at UCI between 1998 and 2002. Participants were assessed before, during, and after the program using multiple measures of competencies in family medicine topics, practice, and teaching. Aggregate participant data, post-program quality surveys, and follow-up surveys of the program's influence on practice behaviors comprised the main measures used for program evaluation. RESULTS: Participants showed improvement in knowledge and skills for family medicine practice and teaching for topics covered in the program. After returning to Egypt, 98% reported continued use of their newly acquired skills and knowledge. Participants reported that the program advanced their careers, they taught family medicine to other physicians, and they were likely to pursue certification under a newly established Family Medicine Board of Egypt. Self-reported practice in family medicine increased to 69% after the program versus 16% before. CONCLUSIONS: Overseas training programs are a viable method of introducing family medicine as a new clinical specialty. Ingredients for successful implementation and barriers are discussed.
