Integrating Basic and Clinical Sciences Using Point-of-Care Renal Ultrasound for Preclerkship Education.

ABSTRACT:

Introduction

Point-of-care ultrasound (POCUS) is a valuable asset in bedside clinical care. Undergraduate medical education is increasingly using POCUS as an adjunct tool for teaching anatomy, pathophysiology, and physical exam in an integrated manner. Many medical schools teach content in an organ systems-based format in the preclerkship years. POCUS teaching can be very effectively tailored to specific organ systems. Though pilot curricula for generalized ultrasound education exist, few teach organ systems-based content using POCUS. To address this gap, we designed and implemented an integrated POCUS module to supplement anatomy, pathophysiology, and physical exam teaching in the renal course.

Methods

The module consisted of (1) a 30-minute didactic lecture introducing students to renal ultrasound technique and image interpretation and (2) a practical hands-on skills session. Pre- and postmodule surveys assessed the efficacy and impact of the curriculum.

Results

A total of 31 first-year medical students completed the POCUS renal curriculum. A majority reported that the module positively affected their understanding of renal pathophysiology and the physical exam. They also reported increased confidence in using POCUS to detect renal pathology and make clinical decisions.

Discussion

It was feasible to implement a POCUS curriculum to supplement integrated teaching of renal system concepts in the first year of medical school, and students found POCUS teaching valuable. POCUS provides educators with another tool to integrate basic and clinical sciences with hands-on relevant clinical skills practice in early medical school years.

Project description:BackgroundPoint-of-Care-Ultrasound (POCUS) curricula have rapidly expanded in undergraduate medical education (UME). However, the assessments used in UME remain variable without national standards. This scoping review characterizes and categorizes current assessment methods using Miller's pyramid for skills, performance, and competence of POCUS in UME. A structured protocol was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). A literature search of MEDLINE was performed from January 1, 2010, to June 15, 2021. Two independent reviewers screened all titles and abstracts for articles that met inclusion criteria. The authors included all POCUS UME publications in which POCUS-related knowledge, skills, or competence were taught and objectively assessed. Articles were excluded if there were no assessment methods used, if they exclusively used self-assessment of learned skills, were duplicate articles, or were summaries of other literature. Full text analysis and data extraction of included articles were performed by two independent reviewers. A consensus-based approach was used to categorize data and a thematic analysis was performed.ResultsA total of 643 articles were retrieved and 157 articles met inclusion criteria for full review. Most articles (n = 132; 84%) used technical skill assessments including objective structured clinical examinations (n = 27; 17%), and/or other technical skill-based formats including image acquisition (n = 107; 68%). Retention was assessed in n = 98 (62%) studies. One or more levels of Miller's pyramid were included in 72 (46%) articles. A total of four articles (2.5%) assessed for students' integration of the skill into medical decision making and daily practice.ConclusionsOur findings demonstrate a lack of clinical assessment in UME POCUS that focus on integration of skills in daily clinical practice of medical students corresponding to the highest level of Miller's Pyramid. There exists opportunities to develop and integrate assessment that evaluate higher level competencies of POCUS skills of medical students. A mixture of assessment methods that correspond to multiple levels of Miller's pyramid should be used to best assess POCUS competence in UME.

Project description:ObjectivesImplementation barriers and lack of standardized point-of-care ultrasound (POCUS) curricula make the development of effective POCUS curricula and methods of assessment challenging. The authors aim to develop a longitudinal POCUS curriculum through staged intervention. In the first stage, the authors hypothesized that the use of high-fidelity ultrasound simulation during the Internal Medicine clerkship would improve POCUS confidence and knowledge among medical students, minimizing the need for trained faculty.MethodsA quasi-experimental study of third-year students on the Internal Medicine clerkship at a large academic medical center in the United States was performed assessing the efficacy of ultrasound simulation use. The control group consisted of students who received baseline POCUS education during teaching rounds but did not have access to the ultrasound simulator. The experimental group consisted of students who, in addition to baseline POCUS education, had access to a high-fidelity ultrasound simulator throughout the clerkship for a minimum of 1 hour per week. Students in both the control and experimental groups completed a pre- and post-intervention confidence survey and knowledge-based examination.ResultsEighty-two percent (50/61) of students completed pre- and post-tests, with the control group demonstrating no significant difference in POCUS confidence or knowledge. After exposure to the ultrasound simulator, the experimental group demonstrated statistically significant improvement in POCUS confidence and overall POCUS knowledge (p < .01).ConclusionThe use of high-fidelity ultrasound simulation can improve POCUS confidence and knowledge among medical students while addressing common barriers to the implementation of a POCUS curriculum. Despite showing statistically significant improvement in overall knowledge, the results did not appear to hold educational significance. Additional POCUS educational methods are necessary to overcome cognitive bias and potential overconfidence. The next stage of curriculum development will include resident-led POCUS workshops to supplement simulation.

Project description:BackgroundCurriculum development and implementation for internal medicine point-of-care ultrasound (IM POCUS) continues to be a challenge for many residency training programs. Education indicators may provide a useful framework to support curriculum development and implementation efforts across programs in order to achieve a consistent high-quality educational experience.ObjectiveThis study seeks to establish consensus-based recommendations for education indicators for IM POCUS training programs in Canada.DesignThis consensus study uses a modified nominal group technique for voting in the initial round, followed by two additional rounds of online voting, with consensus defined as agreement by at least 80% of the participants.ParticipantsParticipants were 22 leaders with POCUS and/or education expertise from 13 Canadian internal medicine residency programs across 7 provinces.Main measuresEducation indicators considered were those that related to aspects of the POCUS educational system, could be presented by a single statistical measure, were readily understood, could be reliably measured to provide a benchmark for measuring change, and represented a policy issue. We excluded a priori indicators with low feasibility, are impractical, or assess learner reactions. Candidate indicators were drafted by two academic internists with post-graduate training in POCUS and medical education. These indicators were reviewed by two internists with training in quality improvement prior to presentation to the expert participants.Key resultsOf the 52 candidate education indicators considered, 6 reached consensus in the first round, 12 in the second, and 4 in the third round. Only 5 indicators reached consensus to be excluded; the remaining indicators did not reach consensus.ConclusionsThe Canadian Internal Medicine Ultrasound (CIMUS) group recommends 22 education indicators be used to guide and monitor internal medicine POCUS curriculum development efforts in Canada.
