The Simulated Cardiology Clinic: A Standardized Patient Exercise Supporting Medical Students' Biomedical Knowledge and Clinical Skills Integration

Foundational and Clinical Science Integration in a Team-Based Learning Module Modeling Care of a Patient With Dyslipidemia

Introduction

Foundational and clinical science integration, a long-standing goal of undergraduate medical education, benefits learners by promoting retention of critical knowledge and skills as well as their transfer to the clinical setting. We implemented a team-based learning (TBL) module in which foundational knowledge and skills from the disciplines of biochemistry, nutrition, and genetics were leveraged in a simulated patient encounter for diagnosis and management of a patient with dyslipidemia.

Methods

The TBL was deployed in a first-year medical student cardiovascular system course with 125 students over three academic years. Following individual and team readiness assurance tests (iRAT and tRAT, respectively), teams participated in an initial application exercise requiring consideration of clinical and laboratory data and other risk factors to engage the patient in a shared decision-making process. Using dietary and family history narratives in subsequent application exercises, teams completed recommendations for an individualized diet plan and an assessment of potential disease inheritance patterns to formulate appropriate patient care management strategies.

Results

Student engagement with prelearning materials and session team activities was high as judged by RAT performance and application exercise outcomes: iRAT question performance ranged from 89% to 99% for individual items, and tRAT performance was routinely 100%. Learners reported that the exercises were impactful and believed the learned foundational knowledge and skills were transferable to future patient care.

Discussion

The dyslipidemia TBL module provides an illustration for early clinical learners of how foundational knowledge and skills can be operationalized and transferred for optimal patient care.

Listen Before You Auscultate: An Active-Learning Approach to Bedside Cardiac Assessment

Introduction

Bedside cardiac assessment (BCA) is deficient across a spectrum of noncardiology trainees. Learners not taught BCA well may become instructors who do not teach well, creating a self-perpetuating problem. To improve BCA teaching and learning, we developed a high-quality, patient-centered curriculum for medicine clerkship students that could be flexibly implemented and accessible to other health professions learners.

Methods

With a constructivist perspective, we aligned learning goals, activities, and assessments. The curriculum used a "listen before you auscultate" framework, capturing patient history as context for a six-step, systematic approach. In the flipped classroom, short videos and practice questions preceded two 1-hour class activities that integrated diagnostic reasoning, pathophysiology, physical diagnosis, and reflection. Activities included case discussions, jugular venous pressure evaluation, heart sound competitions, and simulated conversations with patients. Two hundred sixty-eight students at four US and international medical schools participated. We incorporated feedback, performed thematic analysis, and assessed learners' confidence and knowledge.

Results

Low posttest data capture limited quantitative results. Students reported increased confidence in BCA ability. Knowledge increased in both BCA and control groups. Thematic analysis suggested instructional design strategies were effective and peer encounters, skills practice, and encounters with educators were meaningful.

Discussion

The curriculum supported active learning of day-to-day clinical competencies and promoted professional identity formation alongside BCA ability. Feedback and increased confidence on the late-clerkship posttest suggested durable learning. We recommend approaches to confirm this and other elements of knowledge, skill acquisition, or behaviors and are surveying impacts on professional identity formation-related constructs.

Learning abnormal physical examination signs: an introductory course

CONTEXT

The acquisition of clinical skills is an essential part of the osteopathic medical school curriculum. Preclinical medical students, especially at osteopathic medical schools, have limited exposure to abnormal physical examination (PE) findings that are not typically seen in a student's peers or in a standardized patient (SP). The early exposure of first-year medical students (MS1s) to normal and abnormal findings in the simulation settings better equips them to identify abnormalities when they encounter them in a clinical setting.

OBJECTIVES

The aim of this project was to develop and implement the introductory course on learning abnormal PE signs and pathophysiology of abnormal clinical findings to address the educational needs of MS1s.

METHODS

The didactic part of the course consisted of PowerPoint presentations and lecture on the topics related to the simulation. The practical skill session was 60 min, during which time students first practiced PE signs and then were assessed on their ability to accurately identify abnormal PE signs on a high-fidelity (HF) mannequin. Faculty instructors guided students through clinical cases and challenged them with probing questions in clinically relevant content. Before- and after-simulation evaluations were created to assess students' skills and confidence. Student satisfaction levels after the training course were also assessed.

RESULTS

This study demonstrated significant improvements in five PE skills (p<0.0001) after the introductory course of abnormal PE clinical signs. The average score for five clinical skills increased from 63.1 to 88.74% (before to after simulation). The confidence of students in performing clinical skills and their understanding of the pathophysiology of abnormal clinical findings also increased significantly (p<0.0001) after simulation activity and educational instruction. The average confidence score increased from 3.3 to 4.5% (before to after simulation) on a 5-point Likert scale. Survey results demonstrated high satisfaction with the course among learners with mean satisfaction score 4.7 ± 0.4 on 5-point Likert scale. The introductory course was well received by MS1s and they left positive feedback.

CONCLUSIONS

This introductory course offered MS1s with novice PE skills the ability to learn a variety of abnormal PE signs, including heart murmurs and rhythms, lung sounds, measurement of blood pressure (BP), and palpation of the femoral pulse. This course also allowed abnormal PE findings to be taught in a time-efficient and faculty-resource-efficient manner.

Cardiac Physical Exam Skills and Auscultation Session for Pediatric Interns

Introduction

Physicians need adequate physical exam skills. Unfortunately, interns have variable physical exam skills, and teaching is often limited to rounds, an inconsistent setting. Physical exam skills, particularly those involving auscultation, require practice. Our goal was to create a cardiac physical exam workshop for pediatric interns that would improve their performance on an interactive assessment of their ability and understanding in physical exam and murmur interpretation.

Methods

We completed a targeted needs assessment and then developed a 2-hour workshop on the pediatric cardiac physical exam targeted to pediatrics residents. The workshop included didactics, group discussion, and practice interpreting common pediatric murmurs. Pediatrics residents completed the assessment as a pretest and then participated in the workshop. At the end of the workshop, the assessment was administered as a posttest, followed by a reassessment 3 months later. Nonparametric statistical analysis was conducted. Pre- and posttest scores were compared using the Wilcoxon signed rank test.

Results

Twenty-five residents completed the workshop, including 22 pediatrics residents, one pediatrics/anesthesia combined resident, one pediatric neurology resident, and one resident completing a preliminary year in pediatrics prior to dermatology residency. There was a significant increase in the mean score on the assessment from pre- to posttest (pretest M = 54%, posttest M = 71%, p < .001). This increase was sustained at the 3-month reassessment (M = 67%).

Discussion

This cardiac physical exam workshop demonstrated improvement in physical exam knowledge and interpretation ability as measured by an online pre-/posttest.

Antiviral Pharmacology: A Standardized Patient Case for Preclinical Medical Students

INTRODUCTION

Pharmacology is an important learning topic in preclinical medical education. Simulated patient encounters allow students to apply basic science knowledge in a clinical setting and have been useful in previous studies of pharmacology education. We developed a standardized patient (SP) encounter to reinforce antiviral pharmacology content for first-year medical students.

METHODS

Students were instructed to recommend a medication for shingles during an SP encounter and to answer questions from the SP on mechanism of action and adverse effects. Students then attended a large-group debrief session. Following the activity, students evaluated the exercise through a voluntary survey. For knowledge assessment, students were randomized into two groups to complete three multiple-choice questions either before or after the learning activity.

RESULTS

In 2020 and 2021, 144 and 145 students, respectively, participated. In 2020, there was no significant difference in the proportion of correct answers between the pre- and postsimulation groups (p > .05). In 2021, the postsimulation group significantly outperformed the presimulation group in knowledge of mechanism of action (p < .01) and adverse effects (p < .01), but no difference was seen between the groups regarding medication selection (p = .27). Most learners assessed the instructional design as effective for the tasks assigned.

DISCUSSION

This SP activity provided an opportunity for early medical students to practice integrating antiviral pharmacology knowledge into a patient encounter and was well received by learners. The instructional method offers a clinically relevant approach for reinforcing pharmacology knowledge for preclinical medical students.
