Auctions and Leaks: A Theoretical and Experimental Investigation

We study first- and second-price private value auctions with sequential bidding where second movers may discover the first movers bids. There is a unique equilibrium in the first-price auction and multiple equilibria in the second-price auction. Consequently, comparative statics across price rules are equivocal. We experimentally find that in the first-price auction, leaks benefit second movers but harm first movers and sellers. Low to medium probabilities of leak eliminate the usual revenue dominance of first-price over second-price auctions. With a high probability of a leak, second-price auctions generate higher revenue

Validity Evidence for the Core Physical Examination in Medical Students

Purpose: The Core Physical Exam (CPE) has been proposed as a basis for the Core + Cluster curriculum for teaching and assessing physical examination (PE) skills in medical students. This study provides initial validity evidence for a modified, institution-specific CPE as an assessment of PE skills in medical students. Methods. The University of Colorado School of Medicine (UCSOM) CPE was developed as a 25- item version of the published CPE. Validity evidence for the UCSOM CPE was gathered using data from two classes of approximately 180 medical students from to September 2015 to December 2018. Validity evidence specific to content, response process, internal structure, relationship to other variables and consequences was gathered. Results: Content and response process evidence was based on the use of content experts to develop the UCSOM CPE and the extensive rater training in the institution’s clinical performance center. Correlations of performance on the UCSOM CPE to other assessments of the PE were generally low in the range of 0.14 to 0.23, consistent with correlations between stations of objective structured clinical examinations. The 90% pass-fail cut point determined by a modified Angoff approach resulted in a fail rate of 10% to 13% for the UCSOM CPE in first year and 36% to 38% in second year. Clinical skills course directors selected a consensus passfail cut score of 80% as a defensible and practical threshold for the UCSOM CPE in its current educational context for entry into supervised clinical practice in the context of a preceptorship experience. Conclusion: Initial validity evidence supports the use of UCSOM CPE as a useful educational strategy for teaching physical examination and as a formative assessment of PE competence in medical students

Taking Advantage of the Teachable Moment: A Review of Learner-Centered Clinical Teaching Models

When working in a chaotic Emergency Department (ED) with competing priorities, clinical teaching may be sacrificed for the sake of patient flow and throughput. An organized, efficient approach to clinical teaching helps focus teaching on what the learner needs at that moment, incorporates regular feedback, keeps the department on track, and prevents over-teaching. Effective clinical teaching in a busy environment is an important skill for senior residents and faculty to develop. This review will provide a critique and comparison of seven structured teaching models to better prepare readers to seize the teachable moment

Impact of a Dedicated Teaching Attending Experience on a Required Emergency Medicine Clerkship

Introduction: One published strategy for improving educational experiences for medical students in the emergency department (ED) while maintaining patient care has been the implementation of dedicated teaching attending shifts. To leverage the advantages of the ED as an exceptional clinical educational environment and to address the challenges posed by the rapid pace and high volume of the ED, our institution developed a clerkship curriculum that incorporates a dedicated clinical educator role – the teaching attending – to deliver quality bedside teaching experiences for students in a required third-year clerkship. The purpose of this educational innovation was to determine whether a dedicated teaching attending experience on a third-year required emergency medicine (EM) clerkship would improve student-reported clinical teaching evaluations and student-reported satisfaction with the overall quality of the EM clerkship.Methods: Using a five-point Likert-type scale (1 - poor to 5 - excellent), student-reported evaluation ratings and the numbers of graduating students matching into EM were trended for 10 years retrospectively from the inception of the clerkship for the graduating class of 2009 through and including the graduating class of 2019. We used multinomial logistic regression to evaluate whether the presence of a teaching attending during the EM clerkship improved student-reported evaluation ratings for the EM clerkship. We used sample proportion tests to assess the differences between top-box (4 or 5 rating) proportions between years when the teaching attending experience was present and when it was not. Results: For clinical teaching quality, when the teaching attending is present the estimated odds of receiving a rating of 5 is 77.2 times greater (p <0.001) than when the teaching attending is not present and a rating of 4 is 27.5 times greater (p =0.0017). For overall clerkship quality, when the teaching attending is present, the estimated odds of receiving a rating of 5 is 13 times greater (p <0.001) and a rating of 4 is 5.2 times greater (p=0.0086) than when the teaching attending is not present.Conclusion: The use of a dedicated teaching attending shift is a successful educational innovation for improving student self-reported evaluation items in a third-year required EM clerkship

Ethical Considerations in Education Research in Emergency Medicine

The 2012 Academic Emergency Medicine consensus conference on education research in emergency medicine (EM) addressed various issues, including that of ethics in medical education research for EM. Education research in EM is essential to patient care and safety, and with recent advances in simulation and the advent of the Milestones project, it will become even more vital. Education research in EM is guided by the same principles that guide the ethical conduct of all human subjects\u27 research: respect for persons, beneficence, and justice. Regulatory provisions and widely accepted ethical standards provide a framework for research in EM education; however, special considerations exist for education research. To ensure patient and trainee safety and to maintain the integrity of new knowledge, ethical considerations should remain at the forefront of EM education research. For EM education researchers, recognition of the vulnerability of residents, medical students, and others as research subjects is paramount. This article fills an important gap by outlining the principles guiding education research in EM, exploring the ethical challenges and approaches to education research, and offering a framework and future directions for the ethical conduct of education research in EM

Defining a core curriculum for education scholarship fellowships in emergency medicine.

A trained cadre of medical education scholars with a focus on methodologically sound research techniques is needed to ensure development of innovations that can be translated to educational practice, rigorous evaluation of instructional strategies, and progress toward improving patient care outcomes. Most established educational programs are aimed at existing faculty members and focus primarily on the development of teaching and leadership skills. At the 2012 Academic Emergency Medicine (AEM) consensus conference, "Education Research in Emergency Medicine: Opportunities, Challenges, and Strategies for Success," a breakout session was convened to develop training recommendations for postgraduate fellowship programs in medical education scholarship that would enable residency graduates to join academic faculties armed with the skills needed to perform research in medical education. Additionally, these graduates would enjoy the benefits of established mentorships. A group of 23 medical education experts collaborated to address the following objectives: 1) construct a formal needs assessment for fellowship training in medical education scholarship in emergency medicine (EM), 2) compare and contrast current education scholarship programs in both EM and non-EM specialties, and 3) develop a set of core curriculum guidelines for specialized fellowship training in medical education scholarship in EM. Fellowship-trained faculty need to be proficient in learner instruction and assessment, organizational leadership, curriculum development, educational methodology, and conducting generalizable hypothesis-driven research to improve patient care
