A multisite randomized trial of implicit versus explicit modeling in clinical teaching.

PURPOSE: Faculty modeling of desired behaviors has historically been a part of the apprenticeship model of clinical teaching, yet little is known about best practices for modeling. This study compared the educational impact of implicitly versus explicitly modeled communication skills among U.S. medical students. METHOD: Fourth-year medical students from six U.S. academic medical centers were randomly assigned one simulated clinical encounter in which faculty provided either implicit or explicit modeling of important communication skills. Outcomes were assessed by electronic surveys immediately before and after the simulations. Students were blinded to the purpose of the study. RESULTS: Students in the explicit arm were more likely to correctly cite two of the three key specific communication elements modeled by faculty: deliberate body position (53.3% vs. 18.6%, p < 0.001) and summarizing patient understanding (62.2% vs. 11.6%, p < 0.001). More students in the explicit study arm reported faculty 'demonstrated a key behavior that they wanted me to be able to perform in the future' (93.2% versus 62.8%, p = 0.002). Participating faculty stated they would modify their teaching approach in response to their experiences in the study. CONCLUSIONS: In a multi-center randomized trial, explicit faculty role-modeling led to greater uptake of communication knowledge, greater recognition of skills, and a greater sense that faculty expected these skills to be adopted by students. These results must be considered in the context, however, of a simulated environment and a short timeframe for assessing learning with students who volunteered for a simulated experience.

Experimental Biology 2020 Meeting Abstracts.

NYU School of Medicine recently embarked on a re-design of its anatomy curriculum that decreased the use of cadavers with plastinated specimens. Plastinated models provide an authentic learning experience of the human body, but lack necessary labels outlining important structures. Due to the fragile nature of the specimens, we endeavored to solve the challenge of labeling by developing a digitized supplement and archive of plastinated and pathology specimens. An interdisciplinary team of faculty and multimedia designers at NYU School of Medicine designed and developed electronic resources related to the artistic models and plastinated specimens. Over the course of three months, 60 artistic and plastinated models of different sizes were captured from dozens of angles using a digital camera or an Artec Leo Scanner. The numerous image captures of the plastinated specimens were processed in Agisoft Metashape, a stand-alone software product, that performs photogrammetric processing of digital images and generates 3D spatial data. After Agisoft Metashape exported a complex 3D mesh with a high-resolution texture, anatomy faculty added labels to the digitized 3D anatomy specimens using the Sketchfab web platform. The labeled 3D anatomy models were then uploaded into the Living Anatomy site on NYU School of Medicine's learning management system for students to explore before, during, and after their anatomy lab sessions. Quizzes using these models also were created to help students identify the structures and link them to physiology and clinical scenarios. The digitized 3D models allow students to zoom in, rotate and explore the specimens in a more interactive way, thereby enhancing the process of just observing fragile plastination models. When asked, 84% of students reported that the 3D models of plastinated specimens contributed "very much so" to their learning of anatomical relationships. We will continue to find opportunities for the meaningful integration of these 3D models within the anatomy curriculum as well as into other pre-clerkship and clerkship modules. We will also assess the educational outcomes of the 3D models and, by doing so, will incorporate instructional design into the process.

Measuring professional identity formation early in medical school.

AIM: To assess the feasibility and utility of measuring baseline professional identity formation (PIF) in a theory-based professionalism curriculum for early medical students. METHODS: All 132 entering students completed the professional identity essay (PIE) and the defining issues test (DIT2). Students received score reports with individualized narrative feedback and wrote a structured reflection after a large-group session in which the PIF construct was reviewed. Analysis of PIEs resulted in assignment of a full or transitional PIF stage (1-5). The DIT2 score reflects the proportion of the time students used universal ethical principles to justify a response to 6 moral dilemma cases. Students' reflections were content analyzed. RESULTS: PIF scores were distributed across stage 2/3, stage 3, stage 3/4, and stage 4. No student scores were in stages 1, 2, 4/5, or 5. The mean DIT2 score was 53% (range 9.7?76.5%); the correlation between PIF stage and DIT score was ρ = 0.18 (p = 0.03). Students who took an analytic approach to the data and demonstrated both awareness that they are novices and anticipation of continued PIF tended to respond more positively to the feedback. CONCLUSIONS: These PIF scores distributed similarly to novice students in other professions. Developmental-theory based PIF and moral reasoning measures are related. Students reflected on these measures in meaningful ways suggesting utility of measuring PIF scores in medical education.

The biodigital human: a web-based 3D platform for medical visualization and education.

NYU School of Medicine's Division of Educational Informatics in collaboration with BioDigital Systems LLC (New York, NY) has created a virtual human body dataset that is being used for visualization, education and training and is accessible over modern web browsers.

Does a measure of Medical Professional Identity Formation predict communication skills performance?

OBJECTIVE: To validate an approach to measuring professional identity formation (PIF), we explore if the Professional Identity Essay (PIE), a stage score measure of medical professional identity (PI), predicts clinical communication skills. METHODS: Students completed the PIE during medical school orientation and a 3-case Objective Structured Clinical Exam (OSCE) where standardized patients reliably assessed communication skills in 5 domains. Using mediation analyses, relationships between PIE stage scores and communication skills were explored. RESULTS: For the 351 (89%) consenting students, controlling for individual characteristics, there were increases in patient counseling (6.5%, p<0.01), information gathering (4.3%, p = 0.01), organization and management (4.1%, p = 0.02), patient assessment (3.6%, p = 0.04), and relationship development (3.5%, p = 0.03) skills for every half stage increase in PIE score. The communication skills of lower socio-economic status (SES) students are indirectly impacted by their slightly higher PIE stage scores. CONCLUSION: Higher PIE stage scores are associated with higher communication skills and lower SES. PRACTICE IMPLICATIONS: PIE predicts critical clinical skills and identifies how SES and other characteristics indirectly impact future clinical performance, providing validity evidence for using PIE as a tool in longitudinal formative academic coaching, program and curriculum evaluation, and research.

Effects of Moving the United States Medical Licensing Examination Step 1 After Core Clerkships on Step 2 Clinical Knowledge Performance.

PURPOSE: To investigate the effect of a change in the United States Medical Licensing Examination Step 1 timing on Step 2 Clinical Knowledge (CK) scores, the effect of lag time on Step 2 CK performance, and the relationship of incoming Medical College Admission Test (MCAT) score to Step 2 CK performance pre and post change. METHOD: Four schools that moved Step 1 after core clerkships between academic years 2008-2009 and 2017-2018 were analyzed. Standard t tests were used to examine the change in Step 2 CK scores pre and post change. Tests of differences in proportions were used to evaluate whether Step 2 CK failure rates differed between curricular change groups. Linear regressions were used to examine the relationships between Step 2 CK performance, lag time and incoming MCAT score, and curricular change group. RESULTS: Step 2 CK performance did not change significantly (P = .20). Failure rates remained highly consistent (pre change: 1.83%; post change: 1.79%). The regression indicated that lag time had a significant effect on Step 2 CK performance, with scores declining with increasing lag time, with small but significant interaction effects between MCAT and Step 2 CK scores. Students with lower incoming MCAT scores tended to perform better on Step 2 CK when Step 1 was after clerkships. CONCLUSIONS: Moving Step 1 after core clerkships appears to have had no significant impact on Step 2 CK scores or failure rates, supporting the argument that such a change is noninferior to the traditional model. Students with lower MCAT scores benefit most from the change.

Moving the United States Medical Licensing Examination Step 1 After Core Clerkships: An Outcomes Analysis.

PURPOSE: Schools undergoing curricular reform are reconsidering the optimal timing of Step 1. This study provides a psychometric investigation of the impact on United States Medical Licensing Examination Step 1 scores of changing the timing of Step 1 from after completion of the basic science curricula to after core clerkships. METHOD: Data from four schools that recently moved the examination were analyzed in a pre-post format using examinee scores from three years before and after the change. The sample included scores from 2008 through 2016. Several confounders were addressed, including rising national scores and potential differences in cohort abilities using deviation scores and analysis of covariance (ANCOVA) controlling for Medical College Admission Test (MCAT) scores. A resampling procedure compared study schools' score changes versus similar schools' in the same time period. RESULTS: The ANCOVA indicated postchange Step 1 scores were higher compared with prechange (adjusted difference = 2.67; 95% confidence interval: 1.50-3.83, P < .001; effect size = 0.14) after adjusting for MCAT scores and rising national averages. The average score increase in study schools was larger than changes seen in similar schools. Failure rates also decreased from 2.87% (n = 48) pre change to 0.39% (n = 6) post change (P < .001). CONCLUSIONS: Results suggest moving Step 1 after core clerkships yielded a small increase in scores and a reduction in failure rates. Although these small increases are unlikely to represent meaningful knowledge gains, this demonstration of "noninferiority" may allow schools to implement significant curricular reforms.

Professional Identity Formation in medical school: One measure reflects changes during pre-clerkship training.

This article was migrated. The article was marked as recommended. Professional Identity Formation (PIF), the process of internalizing a profession's core values and beliefs, is an explicit goal of medical education. The Professional Identity Essay (PIE), a developmental measure of the extent to which individuals have a complex and self-defined understanding of their professional role, is a tool to both study and scaffold PIF. PIE staging has internal reliability and response process validity and correlates with a validated measure of moral reasoning. In this study, we investigate whether PIF, as measured by PIE, changes during pre-clerkship training. Medical students in the class of 2019 completed the PIE during orientation to medical school (PIE#1) and 15 months later, during orientation to clerkships (PIE#2), to the same prompts. These written responses are PIF-staged by an expert rater. On average, PIF scores reveal that 46% of the group remained at the same stage as they were on entry to medical school, 42% scored at a higher stage of PIF, and 15% of students scored at a lower stage of PIF after pre-clerkship training. This result suggests that medical students are heterogeneous with respect to the development of their medical PIF early in medical school training.
