Pelvis Anatomy Tutorial Using Radiological Images

Incorporating ultrasound training into undergraduate medical education in a faculty-limited setting

BACKGROUND

Point of care ultrasound (POCUS) is becoming a major extension of patient care. From diagnostic efficacy to its widespread accessibility, POCUS has expanded beyond emergency departments to be a tool utilized by many specialties. With the expansion of its use, medical education has begun to implement ultrasound education earlier in curricula. However, at institutions without a formal ultrasound fellowship or curriculum, these students lack the fundamental knowledge of ultrasound. At our institution, we set out to incorporate an ultrasound curriculum, into undergraduate medical education utilizing a single faculty member and minimal curricular time.

METHODS

Our stepwise implementation began with the development of a 3-hour fourth-year (M4) Emergency Medicine clerkship ultrasound teaching session, which included pre- and post-tests as well as a survey. The success with this session progressed to the development of a designated fourth-year ultrasound elective, which was evaluated with narrative feedback. Finally, we developed six 1-hour ultrasound sessions that correlated with first-year (M1) gross anatomy and physiology. A single faculty member was responsible for this curriculum and other instructors included residents, M4 students, and second-year (M2) near-peer tutors. These sessions also included pre- and post-tests and a survey. Due to curricular time limitations, all but the M4 Emergency Medicine clerkship session were optional.

RESULTS

87 students participated in the emergency medicine clerkship ultrasound session and 166 M1 students participated in the voluntary anatomy and physiology ultrasound sessions. All participants agreed or strongly agreed that they would like more ultrasound training, that ultrasound training should be integrated into all four years of undergraduate medical education. Students were in strong agreement that the ultrasound sessions helped increase understanding of anatomy and anatomical identification with ultrasound.

CONCLUSION

We describe the stepwise addition of ultrasound into the undergraduate medical education curriculum of an institution with limited faculty and curricular time.

Learning Head and Neck Anatomy Through a Radiological Imaging Platform

INTRODUCTION

Head and neck anatomy is complex for students to learn and educators to teach. Instructing students on anatomy using radiological imaging can aid comprehension and prepare them for future clinical practice. Computer-aided anatomy instruction is accessible to diverse learners and avoids barriers identified with face-to-face teaching.

METHODS

We designed a self-guided PowerPoint tutorial with multiple medical imaging modalities, clinical correlations, and self-review questions incorporated throughout. The tutorial was evaluated with a group of 178 Australian preclinical medical students who had prior teaching related to head and neck anatomy. Student participants were divided into experimental and control groups. Participants completed two knowledge assessments: experimental group before and after tutorial engagement and control group before tutorial engagement. All participants were invited to provide feedback on their experiences with the tutorial via questionnaires.

RESULTS

Engagement with the tutorial improved overall head and neck anatomy knowledge (p < .001). Knowledge outcomes were maintained across question group type (e.g., multiple-choice questions, identification, and short-answer questions; p < .05), with participants reporting 96% overall positive feedback related to the tutorial experience.

DISCUSSION

Given the improved outcomes following tutorial exposure, our results suggest that this tutorial is efficacious when used in concert with existing anatomy curricula. Participants' perceived value of the tutorial additionally suggests that it would be taken up well by medical students and is an effective addition to the existing tutorial series. Further research is needed to assess the tutorial's use as a stand-alone addition to the anatomy curriculum.

Effectiveness of blended learning in radiological anatomy for first year undergraduate medical students

PURPOSE

The aim of the study was to assess the effectiveness of blended learning modules for radiological anatomy among first-year medical students by estimating knowledge gain and evaluating student perceptions.

METHODS

A single-group, pre- and post-test study design was utilized. Five radiological anatomy modules consisting of online presentations and self-assessment quizzes were developed for the upper limb, lower limb, head and neck, thorax, and abdomen and pelvis. The content of the modules was uploaded on to a learning management system called TYRO. Each module focused on the normal anatomical features observed on plain and contrast radiographs. Other relevant imaging modalities and clinical contexts were also introduced. During the classroom session, the students were instructed to peruse the modules and answer the self-assessment quiz. The teacher in the classroom acted as a facilitator and was available to the students for any clarifications. A pre- and post-test was administered to the students before and after exposure to the modules, respectively. A paired t test was used to estimate differences in the pre- and post-test scores. Students' perceptions were assessed using a questionnaire.

RESULTS

One-hundred students attended both the tests. The mean and standard deviation of pre- and post-test scores were 17 ± 5.5 and 26 ± 7.6, respectively, and this difference was significant. Students' perceptions about the intervention were on the whole positive.

CONCLUSION

A significant improvement in the knowledge of radiological anatomy was noted after exposure to five blended learning modules of radiological anatomy. The modules were well received by the students.

A Novel Approach to Gross Dissection of the Human Pelvis and Perineum

Progressive curricular changes in medical education over the past two decades have resulted in the diaspora of gross anatomy content into integrated curricula while significantly reducing total contact hours. Despite the development of a wide range of alternative teaching modalities, gross dissection remains a critical component of medical education. The challenge posed to modern anatomists is how to maximize and integrate the time spent dissecting under the current curricular changes. In this study, an alternative approach to the dissection of the pelvis and perineum is presented in an effort to improve content delivery and student satisfaction. The approach involves removal of the perineum en bloc from the cadaver followed by excision of the pubic symphysis, removal and examination of the bladder and associated structures, examination and bisection of the midline pelvic organs in situ, and midsagittal hemisection of the pelvis for identification of the neurovasculature. Results indicate that this novel dissecting approach increases the number of structures identified by 46% ± 14% over current dissecting methods. Survey results indicate that students were better able to integrate lecture and laboratory concepts, understand the concepts, and successfully identify more structures using the new approach (P < 0.05). The concept of anatomic efficiency is introduced and proposed as a standard quantitative measure of gross dissection proficiency across programs and institutions. These findings provide evidence that innovative solutions to anatomy education can be found that help to maintain critical content and student satisfaction in a modern medical curriculum.
