The Effect of an Elective Course in Medical Ethics on Medical Students' Tolerance for Ambiguity.

AbstractPurpose: Tolerance for ambiguity (TFA) is a character trait that is associated with a multitude of benefits for physicians, including increased empathy, greater desire to work in underserved areas, fewer medical errors, enhanced psychological well-being, and lower rates of burnout. Furthermore, it has been shown that TFA is a malleable trait that can be enhanced with interventions such as art courses and group reflection. This study describes the utility of a six-week medical ethics elective course in increasing TFA in first- and second-year medical students.Methods: First- and second-year medical students were enrolled in an elective medical ethics course at Cooper Medical School of Rowan University that guided students in critical thinking, group discussion, and respectful debate regarding various ethical dilemmas in medicine. Students took a validated survey before and after course completion to measure TFA. The average pre- and post-course scores for each semester, as well as the total cohort of 119 students, were compared using paired t-tests.Results: A statistically significant improvement in TFA scores was observed in the overall cohort, as well as in each individual semester of the medical ethics elective course offering.Conclusion: A six-week elective course in medical ethics can significantly improve medical students' TFA.

Implementation of team-based learning (TBL) in a second year medical school course: does prior experience with TBL improve the impact of this pedagogy?

BACKGROUND: We have shown that use of Team-based learning (TBL) in a first-year Infectious Diseases (ID) course improved final examination and course performance. Therefore, we implemented TBL in the second-year Women's Health (WH) course to improve acquisition of course content. We hypothesized that prior experience with TBL in the first-year of medical school would lead to a strong correlation between TBL performance in the first and second years. METHODS: Our study is a retrospective review of student TBL and final examination performance in the ID and WH courses. The ID course has weekly TBL exercises that cover all course material, while the WH course has one TBL that covers a small portion of the course material. Final examination and TBL individual readiness assurance test (iRAT) scores in the ID and WH courses from three classes (n = 226) were obtained with institutional review board approval. Statistical analyses were performed including comparisons of means and correlation studies. RESULTS: Average WH iRAT scores were significantly higher than ID iRAT scores (9.19 vs. 7.40,p < 0.01), and iRAT scores in both courses were highly correlated (r = 0.35,p < 0.01). When stratifying students based on WH course performance, in struggling students, iRAT but not final examination scores were higher in the WH course than the ID course (8.73 vs. 7.00,p < 0.01 and 82.45 vs. 80.51,p > 0.05, respectively). CONCLUSIONS: Our results suggest that prior experience with TBL improves TBL iRAT scores, especially in struggling students. Prior TBL experience is also associated with consistent iRAT performance between first- and second-year courses in high performing students.

Effectiveness of a Team-Based Learning exercise in the learning outcomes of a medical pharmacology course: insight from struggling students.

We have previously reported that multiple Team-Based Learning (TBL™) exercises in a 4-week pre-clinical medical school course improved final exam performance and significantly reduced the number of course failures. Here, we conducted a long-term study, with eight cohorts of first-year medical students, to determine whether the implementation of a single TBL individual readiness assessment test (iRAT) exercise in a 4-week medical school pharmacology course produces similar effects in overall course performance. We implemented a single TBL iRAT exercise that covered the subjects addressed during one week of the medical pharmacology course, with the four most recent cohorts of students matriculating at Cooper Medical School of Rowan University (n = 403). The first four cohorts matriculating at CMSRU did not participate in the TBL exercises (n = 266). Correlation of individual student TBL iRAT and final examination scores in the medical pharmacology course was compared to a second, unrelated first-year course (physiology) to control for variation in student performance between cohorts. We found that there was a significant moderate correlation between final examination and TBL iRAT scores (r = 0.49, p < 0.01, n = 403). Interestingly this moderate correlation was seen in students performing in the lower 25th percentile on the course final examination (r = 0.41, p < 0.01, n = 101) and negligible in students performing in the upper 25th percentile (r = 0.11, n = 101, p > 0.05). Implementation of the single TBL exercise also significantly reduced variance or range of student final examination performance compared to the group of the first four cohorts. These results suggest that implementation of a single TBL exercise, which covers only one week of content delivered in a 1-month medical pharmacology course, benefits first-year medical students by reducing the disparity in knowledge acquisition among them and providing a means to identify students who may struggle with course content.

Assessment of Pathology Learning Modules With Virtual Microscopy in a Preclinical Medical School Curriculum.

OBJECTIVES: To evaluate the ability of pathology modules to promote learning of pathology-related course content in a preclinical medical education curriculum. METHODS: Pathology modules were created for the "Hematology/Oncology" and "Women's Health" (WH) courses. Students were recruited over 2 consecutive academic years; cohorts 1 and 2 refer to 2 separate groups of students in years 1 and 2, respectively, of the study. Course performance data were collected. RESULTS: Use of pathology modules resulted in a statistically significant higher correlation between performance on the final examination and pathology-related questions in the Hematology/Oncology course and written examination and pathology-related questions in cohort 1 in the WH course. There was statistically significant improvement (P = .026) on pathology-related laboratory practical examination questions in the WH course for cohort 1, and no other statistically significant improvement for the other cohorts and examinations. The percentage of students completing all or part of the modules was highest in the WH course for cohort 1 (60%) compared with WH course cohort 2 (33%) and Hematology/Oncology cohort 1 (30%) and cohort 2 (39%). CONCLUSIONS: Pathology modules may improve acquisition and retention of pathology-related course content when used appropriately.

The Utilization of ExamSoft®-iPad® Technology in Administering and Grading Anatomy Practical Examinations.

This article provides a detailed, step-by-step description of the introduction of technology (iPad® use of ExamSoft® web-based assessment software) for administering and grading cadaver-oriented anatomy practical examinations. We explain the advantages of computer-based testing in the delivery and grading of practical examinations, including minimizing human error inherent in hand grading, improving the efficiency of reporting, and mapping the examination to course objectives. Furthermore, item analysis (including item difficulty, discrimination indices, and point biserial correlations) allows evaluation of laboratory teaching and testing and monitoring of the curriculum. We also address how the advantages of this format override any limitation, such as cost. In conclusion, we describe our future directions and how others could adopt this approach.

Parallel Strategies for the Synthesis of Annulated Pyrido[3,4-b]indoles via Rh(I)- and Pd(0)-Catalyzed Cyclotrimerization.

Two different pathways for the synthesis of annulated pyrido[3,4-b]indoles are reported using metal-catalyzed cyclotrimerization reactions. A stepwise process using Rh(I)-catalysis in the final step of the synthesis and a multicomponent, tandem catalytic approach using Pd(0)-catalysis both lead to complex nitrogen-containing heterocycles in good yields. Substituent effects are investigated for both pathways, demonstrating that the Pd(0)-catalyzed approach is more sensitive to electron- withdrawing groups.

Does team-based learning improve performance in an infectious diseases course in a preclinical curriculum?

OBJECTIVES: To examine whether introduction of Team-based Learning (TBL) improves student learning resulting in improved performance on final examination questions and decreased failures in an infectious diseases course. METHODS: To improve mastery of course content, we designed an intervention, which provided weekly TBL exercises in study years 2 and 3 to review concepts presented during didactic lectures and laboratory exercises.  The remaining course structure and content was essentially unchanged. All students taking the course (n=50 in year 1, n=64 in year 2, and n=72 in year 3) participated in this study. Student final examination performance and performance on individual final examination questions were collected and analyzed for changes in response to the study intervention. RESULTS: Addition of weekly TBL exercises improved student performance on the course final examination as demonstrated by a statistically significant increase in the distribution of correct answer percentages for questions in common between the final examinations in years 1 and 2 and between years 1 and 3 (t(99) = 3.1454, p<0.05 and t(99) = 4.1268, p<0.01, respectively; Student-Newman-Keuls).  There was no statistical difference (t(97) = 0.9814, p> 0.05; Student-Newman-Keuls) in the distribution of correct answer percentages between years two and three. There was also a decrease in final examination failures in years two and three. CONCLUSIONS: The results suggest that TBL could be used to improve mastery and retention of course content in a preclinical infectious diseases course. Weekly exercises allow students to identify and ameliorate weaknesses in understanding and make adjustments early in the course.

Reliability and benefits of medical student peers in rating complex clinical skills.

BACKGROUND: Peers have been shown to be reliable raters in an objective structured clinical exam (OSCE). While the literature supports the use of senior level students in rating basic clinical skills, little is known about the reliability of peers of the same level of training in assessing complex clinical skills. AIM: To investigate the reliability of student peers of the same level of training in rating complex clinical skills in a geriatric OSCE. METHODS: Peer (n = 115) ratings were compared to faculty ratings using correlation and generalizability analysis. Paired Wilcoxon Signed-Rank test was used to establish peer learning benefits. RESULTS: Reliability of the OSCE was moderately strong (G-coefficient = 0.70) with strong correlations between peer and faculty ratings for the overall OSCE (r = 0.78, p = 0.001) and for each case (r = 0.70-0.85, p = 0.001). Generalizability analysis indicated that raters contributed minimally to score variance. Peers reported gaining learning benefits from the rating process. CONCLUSION: Peer raters of the same level of training can provide accurate ratings of complex clinical tasks and can serve as an important resource in assessing student performance in an OSCE. The peer review process can also serve an important role in enhancing student learning.

The utilization of forensic science and criminal profiling for capturing serial killers.

Movies and nightly television shows appear to emphasize highly efficient regimens in forensic science and criminal investigative analysis (profiling) that result in capturing serial killers and other perpetrators of homicide. Although some of the shows are apocryphal and unrealistic, they reflect major advancements that have been made in the fields of forensic science and criminal psychology during the past two decades that have helped police capture serial killers. Some of the advancements are outlined in this paper. In a study of 200 serial killers, we examined the variables that led to police focusing their attention on specific suspects. We developed 12 categories that describe how serial killers come to the attention of the police. The results of the present study indicate that most serial killers are captured as a result of citizens and surviving victims contributing information that resulted in police investigations that led to an arrest. The role of forensic science appears to be important in convicting the perpetrator, but not necessarily in identifying the perpetrator.
