RESUMEN

BACKGROUND: In the present assessment environment in undergraduate medical education at U.S. medical schools, the prevalence and implementation of Entrustable Professional Activities (EPAs) in internal medicine (IM) clerkships are not well understood. OBJECTIVE: To describe the prevalence and approach to EPA use in U.S. IM clerkships. DESIGN: Cross-sectional, nationally representative survey of core IM clerkship directors. PARTICIPANTS: One-hundred forty IM clerkship directors at Liaison Committee on Medical Education-accredited U.S./U.S. territory-based allopathic medical schools with membership in the Clerkship Directors in Internal Medicine (CDIM) as of December 2022. MAIN MEASURES: Use of EPAs in IM core clerkships, including use for grading, types of EPAs, use of supportive measures for assessment, and current validity frameworks. KEY RESULTS: The survey response was 80% (112/140); two additional respondents completed the section on EPA use (n = 114). Approximately half of respondents (47%) reported their IM clerkship used EPAs. Among schools accredited after 1977, a higher percentage was associated with having incorporated EPAs (p = 0.03). The Association of American Medical Colleges Core EPAs for Entering Residency (CEPAER) was the most common framework used by Clerkship Directors (CDs) for developing EPAs (55%). Most CDs (56%) used EPAs for both formative and summative assessments, and approximately half of CDs (48%) used EPAs for a portion of the final grade determination. CDs who used EPAs were no more likely to report efforts to ensure the validity of assessment, the use of faculty development, or that written assessments were a valid measure of students' performance compared to those who did not use EPAs. CONCLUSIONS: Although EPAs have experienced substantial uptake in the IM clerkship and contribute to formative and summative assessment of learners, their use does not appear to be associated with enhanced efforts to obtain validity information.

RESUMEN

Background Since 2020, virtual interviews have become the typical way in which applicants assess residency programs. It is unknown whether the change from in-person to virtual interviews has been associated with changes in perceptions of the quality of information gathered by prospective applicants. Objective To ascertain perspectives on the satisfaction with, quality of, and accuracy of information gathered by internal medicine (IM) residency applicants from virtual and in-person interviews. Methods Twenty-nine thousand, seven hundred and seventy-six residents from US and Puerto Rico residency programs sitting for the 2022 American College of Physicians Internal Medicine In-Training Examination (IM-ITE) were surveyed. An optional, 5-question survey was administered at the end of the examination. Responses were analyzed based on interview format-virtual (postgraduate year [PGY]-1-2) or in-person (PGY-3)-and PGY. Results Of 29 776, 23 161 residents responded to the survey (77.8% response rate). Regardless of PGY, respondents reported a high degree of satisfaction with the quality of information gathered from their interview day, though there was a statistically significant difference between virtual and in-person [somewhat/very satisfied: In-person 5938 of 7410 (80.1%); 95% CI [79.2, 81.0] vs virtual 12 070 of 15 751 (76.6%); 95% CI [76.0, 77.3]:P<.001]. Residents in all PGYs reported sessions with residents and one-on-one interviews as the most important factors when creating their rank lists. Conclusions We found differences in satisfaction and perceptions of the quality of information gathered between IM residents who participated in virtual and in-person interviews. However, regardless of format, most respondents reported satisfaction with their interview experience.

RESUMEN

PURPOSE: This study examines how internal medicine clerkship faculty and leadership conceptualize professionalism and professional behaviors and attitudes, identifies whether and how faculty use metrics to assess professionalism and factor it into clerkship grades, and describes barriers that prevent faculty from feeling prepared to support the development of professional behaviors in students. METHOD: The Clerkship Directors in Internal Medicine opened a call for thematic survey section proposals to its physician-faculty members, blind-reviewed all submissions, and selected 4 based on internal medicine clinical clerkship training experience relevance. The survey launched on October 5 and closed on December 7, 2021. Data were analyzed using descriptive statistics. RESULTS: Of 137 core clerkship directors (CDs) at Liaison Committee on Medical Education-accredited medical schools, 103 (75.2%) responded to the survey. Of 102 respondents (1 nonrespondent), 84 (82.4%) identified professional behavior lapses in involvement and 60 (58.8%) identified introspection lapses. Of 103 respondents, 97 (94.2%) reported that their clerkships ask clinical faculty and residents to formally evaluate professionalism, and 64 (62.1%) reported that they factor professionalism assessments into final clerkship grades. CDs reported multiple barriers to addressing professionalism directly with students, including logistical barriers, professionalism assessment subjectivity concerns, and the possible adverse effect of an unprofessional label for students. CONCLUSIONS: Professionalism assessment and remediation in medical education currently center on a deficit model that seeks to identify and remediate professionalism lapses, rather than a developmental model that seeks to nurture growth. This dichotomous characterization of behaviors as professional or unprofessional limits assessment and can adversely affect the learning environment. The authors propose a shift to a developmental model that considers professionalism as a continuous process parallel to the acquisition of clinical skills and medical knowledge.

RESUMEN

BACKGROUND: Transitions of patient care from the inpatient to outpatient setting is a high-risk time often resulting in medical errors and adverse events. Transitions of care programmes have been demonstrated to reduce negative outcomes. Several professional societies have highlighted care transitions as a central pillar of patient care and therefore a crucial aspect of health professional education; however, little data exist on medical student education in this area. APPROACH: The Transitions of Care Curriculum was developed and delivered to all Harvard Medical School Core I Internal Medicine Clerkship students at Beth Israel Deaconess Medical Center, Boston, MA between January 2017 and March 2019, where 12-14 students participated each quarter and included didactic teaching followed by experiential learning. Student data were collected via postclerkship survey. Patient data were collected via chart review. Student self-reported comfort level with transitions in care skills and medical errors were analysed. EVALUATION: All student measures related to comfort with transitions in care skills demonstrated statistically significant improvement after curriculum participation(p < 0.001). Of the patients with a completed postdischarge note, students identified ≥1 postdischarge related issue in 33 of 70 patients, with multiple issues identified in many of these patients. Seventy-six total issues were identified. IMPLICATIONS: The Transitions of Care Curriculum demonstrated promising student and patient outcomes, suggesting that students can successfully learn and advance clinical skills while having a positive impact on a highly needed and important aspect of patient care by reducing postdischarge errors and adverse events.

RESUMEN

PURPOSE: Student-run clinics (SRCs) are prevalent in medical schools. Although these are popular among students and provide ample learning opportunities, these opportunities are not well-characterized. SRCs are poised to support medical schools' ability to meet accreditation standards and student growth and learning, particularly in areas missing from traditional curricula, such as social determinants of health, interprofessional education and inequities. MATERIALS AND METHODS: At the Crimson Care Collaborative (CCC), a network of 7 Harvard Medical School affiliated student-faculty practices in the greater Boston area, we sought to understand what learning opportunities and challenges exist and if a standardized curriculum could improve learning and result in less duplication of teaching efforts. We conducted semi-structured individual interviews of student and faculty leaders and conducted a thematic analysis of the data. RESULTS: Four key themes emerged: (1) Standardization provides opportunities and challenges, (2) Embrace the unique learning opportunities of each clinic, (3) Educational coaches enhance learning opportunities and increase efficiency, (4) Reflection is a useful tool for improvement & learning. DISCUSSION: Our results demonstrate a benefit to both a standardized curriculum for all SRC sites focused on broad clinical, skill-based training and site-specific teaching focusing on the unique clinical needs of each student-run clinic.

RESUMEN

BACKGROUND: "Student-as-Teacher" (SaT) programs have been growing in number to prepare medical students for their teaching roles in residency and beyond, but it remains unknown what content areas should be covered in SaT curricula. AIM: To determine five to ten "essential" content areas for inclusion in SaT curricula using expert opinion. METHODS: Using a three-round Delphi process, moderators iteratively surveyed a panel of 28 medical educators (25 academy directors and three individuals identified as having expertise in undergraduate medical education) representing 25 medical schools in the United States. This "SaT Delphi Working Group" was tasked with rating topics for inclusion in SaT curricula on a 3-point scale (i.e. 1. "essential," 2. "important, but not essential" 3. "not important"). Topics achieving ≥70% consensus as "essential," "important" or "not important" were accepted by the moderators and removed from subsequent rounds. RESULTS: Hundred per cent response rate (n = 28) was achieved for all survey rounds. Five content areas reached consensus as "essential" for inclusion in a SaT curriculum: feedback, bedside teaching and clinical precepting, small-group teaching, case-based teaching and professionalism as a medical educator. CONCLUSION: This consensus from a group of leaders in medical education is a first step toward the implementation of more developmentally-appropriate SaT competencies.

RESUMEN

The changing healthcare environment and movement toward team-based care are contemporary challenges confronting health professional education. The primary care workforce must be prepared with recent national interprofessional competencies to practice and lead in this changing environment. From 2012 to 2014, the weekly Beth Israel Deaconess Crimson Care Collaborative Student-Faculty Practice collaborated with Northeastern University to develop, implement and evaluate an innovative model that incorporated interprofessional education into primary care practice with the goal of improving student understanding of, and ability to deliver quality, team-based care. In the monthly interprofessional clinic, an educational curriculum empowered students with evidence-based, team-based care principles. Integration of nursing, pharmacy, medicine, and masters of public health students and faculty into direct patient care, provided the opportunity to practice skills. The TeamSTEPPS® Teamwork Attitudes Questionnaire was administered pre- and post-intervention to assess its perceived impact. Seventeen students completed the post-intervention survey. Survey data indicated very positive attitudes towards team-based care at baseline. Significant improvements were reported in attitudes towards situation monitoring, limiting personal conflict, administration support and communication. However, small, but statistically significant declines were seen on one team structure and two communication items. Our program provides further evidence for the use of interprofessional training in primary care.

RESUMEN

Although interprofessional relationships are ubiquitous in clinical practice, undergraduate medical students have limited opportunities to develop these relationships in the clinical setting. A few student-faculty collaborative practice networks (SFCPNs) have been working to address this issue, but limited data exist examining the nature and extent of these practices. A systematic survey at a Harvard-affiliated SFCPN is utilised to evaluate the quantity and quality of interprofessional interactions, isolate improvements, and identify challenges in undergraduate interprofessional education (IPE). Our data corroborate previous findings in which interprofessional clinical learning was shown to have positive effects on student development and align with all four domains of Interprofessional Education Collaborative core competencies, including interprofessional ethics and values, roles and responsibilities, interprofessional communication, and teams and teamwork. These results highlight the unique opportunity and growing necessity of integrating IPE in SFCPNs to endorse the development of collaborative and professional competencies in clinical modalities of patient care.

RESUMEN

PROBLEM: In the current transformative health care landscape, it is imperative that clinician educators inspire future clinicians to practice primary care in a dynamic environment. A focus on patient-centered, goal-oriented care for patients with chronic conditions is critical. APPROACH: In 2009, Harvard Medical School founded the Crimson Care Collaborative, a student-faculty collaborative practice (SFCP) network. With the aim of expanding clinical and educational opportunities for medical students and improving patient control of chronic disease (i.e., hypertension, obesity, and diabetes) in an innovative learning environment, in 2012, the authors developed a novel SFCP at their hospital-based academic primary care practice. In this SFCP, students learn to explore patient priorities, provide focused counseling and education, and assist patients with self-management goals during clinical visits. OUTCOMES: From 2012 to 2014, 250 student volunteers participated in the SFCP as clinicians, innovators, educators, and leaders, with between 80 and 95 medical students engaging each semester. Between January 2012 and March 2014, there were 476 urgent care or chronic disease management visits. Patients with chronic diseases were seen at least twice on average, and by 2014, chronic disease management visits accounted for approximately 74% of visits. NEXT STEPS: Work is under way to create assessment tools to evaluate the practice's educa tional impact and student understanding of the current health care system, develop interdisciplinary care teams, expand efforts in registry management and broaden the patient recruitment scope, further emphasize patient engage ment and retention, and evaluate chronic disease management and patient satisfaction effectiveness.

RESUMEN

Poorly designed healthcare systems increase costs and preventable medical errors. To address these issues, systems-based practice (SBP) education provides future physicians with the tools to identify systemic errors and implement quality improvement (QI) initiatives to enhance the delivery of cost-effective, safe and multi-disciplinary care. Although SBP education is being implemented in residency programs and is mandated by the Accreditation Council for Graduate Medical Education (ACGME) as one of its core competencies, it has largely not been integrated into undergraduate medical education. We propose that Medical Student-Faculty Collaborative Clinics (MSFCCs) may be the ideal environment in which to train medical students in SBPs and QI initiatives, as they allow students to play pivotal roles in project development, administration, and management. Here we describe a process of experiential learning that was developed within a newly established MSFCC, which challenged students to identify inefficiencies, implement interventions, and track the results. After identifying bottlenecks in clinic operations, our students designed a patient visit tracker tool to monitor clinic flow and implemented solutions to decrease patient visit times. Our model allowed students to drive their own active learning in a practical clinical setting, providing early and unique training in crucial QI skills.

RESUMEN

CONTEXT: There are few published examples of pathology instruction during the clinical years of medical student training. This lack of exposure to pathology may lead to poor understanding of laboratory testing and the role of pathologists in patient care. OBJECTIVE: To design, implement, and evaluate a pathology curriculum integrated into a longitudinal clerkship for third-year medical students. DESIGN: The curriculum includes an introductory session during the transition week course, pathologist participation in longitudinal student case conferences, and a pathology elective. The curriculum was evaluated by using surveys consisting of both multiple choice and written responses. RESULTS: A total of 55 students participated in the longitudinal curriculum during the 2009-2010 academic year and 8 students, only one of whom stated a career interest in pathology, participated in the elective. More than 80 pathology topics were discussed and, for the first time, pathologists received teaching awards from the third-year students. All elective students would recommend the elective to colleagues; feedback also suggested an improved understanding of pathology as a profession. At the end of the year, 31% of all students, compared to only 19% in the initial survey, knew that most of an anatomic pathologist's caseload consists of specimens from living patients (P  =  .13). In addition, elective student interaction with a pathology faculty member directly led to an improvement in test reporting. CONCLUSIONS: A novel longitudinal curriculum allowed for the creative integration of pathology into third-year students' clinical training and led to better student understanding of the role of pathologists in patient care.

RESUMEN

BACKGROUND: Despite obesity's relevance and impact, curricula addressing obesity are underrepresented in clinical medical education. A novel pilot program to begin teaching medical students about care of the obese patient was developed and student attitudes toward obesity and bariatric surgery were assessed. METHODS: The authors paired third-year students with obese patients undergoing bariatric surgery. Students established a longitudinal patient relationship, received faculty mentorship, and kept a reflections journal. An attitude assessment survey was administered before and after third year. Reflections were analyzed for common themes. RESULTS: Baseline student responses differed from those previously reported for practicing physicians on many survey statements, including more strongly agreeing with the relationship between obesity and serious medical conditions (P < .001), the need to educate patients about obesity risks (P < .001), and willingness to recommend bariatric surgery evaluation (P = .004). These differences were maintained after clinical clerkships. Reflection themes included recognition of obesity stereotypes, improved estimation of body mass index, and awareness of physicians' attitudes about obesity. CONCLUSION: Development and assessment of a novel pilot program to teach third-year medical students about obesity and bariatric surgery suggests a potential impact on student attitudes and understanding of obesity and obesity surgery. Students today may have different attitudes toward obesity than those reflected in prior data for physicians in practice, and programs such as this may help maintain positive attitudes.

RESUMEN

Impaired heart rate response to exercise is associated with adverse clinical outcomes in healthy adults and those with established coronary artery disease. It is unclear whether this association persists in subjects who have undergone coronary artery bypass grafting (CABG). In this study, 920 subjects enrolled in the Post CABG trial who had undergone CABG with patent saphenous vein grafts at baseline and known to have discontinued beta blockers before exercise were studied. A maximal symptom-limited exercise treadmill test was performed on study entry. Chronotropic variables were measured at peak exercise. Participants were followed for a composite end point of death, myocardial infarction, stroke, or revascularization. Quantitative coronary angiography was performed at follow-up and compared with baseline angiography, with prespecified angiographic end points of the substantial progression of graft disease and complete occlusion. In multivariate analysis, a low chronotropic index was strongly associated with an increased risk for the composite clinical end point (p for trend = 0.04) and angiographic complete occlusion (p for trend = 0.007) but only weakly associated with angiographic substantial progression (p for trend = 0.07). In conclusion, impaired chronotropic response to exercise identifies subjects at risk for clinical outcomes and graft occlusion, even after revascularization with CABG.

RESUMEN

OBJECTIVES: This study examines whether obesity accelerates atherogenic progression or adverse outcomes after coronary artery bypass graft (CABG) surgery. BACKGROUND: Obesity is a major risk factor for developing coronary heart disease. Whether obesity accelerates disease progression after CABG is unclear. METHODS: We examined how body mass index (BMI) related to atherosclerotic graft progression and a clinical composite outcome of death, nonfatal myocardial infarction, stroke, CABG surgery, or angioplasty among 1,314 participants in the Post CABG trial. Participants who had undergone CABG surgery were randomly assigned in a 2 x 2 factorial design to warfarin versus placebo and aggressive low-density lipoprotein cholesterol (LDL-C) lowering with lovastatin 40 to 80 mg/day (to achieve LDL-C of 60 to 85 mg/dl) versus moderate LDL-C lowering with lovastatin 2.5 to 5 mg/day (to achieve LDL-C of 130 to 140 mg/dl). Angiographic progression was assessed by coronary angiography at 4 to 5 years. RESULTS: Higher BMI was associated with a higher likelihood of angiographic progression (p trend = 0.003) after adjustment for demographic factors, treatment assignment, smoking status, and years since CABG surgery, but not with clinical events (p trend = 0.81). In stratified analyses, higher BMI was associated with angiographic progression in the low-dose lovastatin group (p trend <0.001) but not in the high-dose group (p = 0.03 for test for interaction of BMI and statin treatment). In the high-dose lovastatin group, higher BMI appeared to be protective against clinical events (p trend = 0.06, test of interaction: 0.02). CONCLUSIONS: Higher BMI is strongly associated with atherogenic progression after CABG surgery. Aggressive statin therapy may be protective against obesity-related acceleration of coronary heart disease.

RESUMEN

BACKGROUND: Physical activity and body mass index (calculated as weight in kilograms divided by height in meters squared) independently alter the risk of coronary heart disease (CHD); however, their combined effect on CHD is not established. Our objective was to study the combined association of physical activity and body mass index on CHD. METHODS: Prospective cohort study of 38,987 women free of cardiovascular disease, cancer, and diabetes at baseline in the Women's Health Study, with 10.9 mean years of follow-up. Weight, height, and recreational activities were reported on entry. Body mass index was categorized as normal weight (<25), overweight (25 to <30), and obese (> or =30). Active was defined as 1000 kilocalories or more expended on recreational activities weekly. Six joint body weight-physical activity categories were defined. The main outcome measure was the occurrence of incident CHD during follow-up, defined as a cardiovascular event including nonfatal myocardial infarction, coronary artery bypass graft, percutaneous transluminal coronary angioplasty, or CHD death. RESULTS: A total of 948 cases of incident CHD occurred during follow-up. Higher body mass index and physical inactivity were individual predictors of CHD. In joint analyses, compared with active normal-weight individuals, the multivariate-adjusted hazard ratios (95% confidence intervals) were 1.54 (1.14-2.08) for overweight-active; 1.87 (1.29-2.71) for obese-active; 1.08 (0.84-1.39) for normal weight-inactive; 1.88 (1.46-2.42) for overweight-inactive; and 2.53 (1.94-3.30) for obese-inactive. Increasing levels of walking also resulted in significant reductions in CHD risk for overweight and obese individuals. CONCLUSIONS: The risk of CHD associated with elevated body mass index is considerably reduced by increased physical activity levels. However, the risk is not completely eliminated, reinforcing the importance of being lean and physically active.

RESUMEN

Recent studies have evaluated the interrelationship between physical activity and body weight on the incidence of chronic diseases such as diabetes and cardiovascular disease (CVD). The combined effect seems to be different and to be dependent on the disease mechanism. Studies reveal that body weight has a greater influence on diabetes, and physical activity plays a greater role in CVD.
