Acetabular fractures are a real challenge for junior doctors as well as experienced orthopedic surgeons. Correct fracture classification is crucial for appreciating the fracture type, surgical planning, and predicting prognosis. Although three-dimensional (3D) tutorial is believed to improve the understanding of the complex anatomy structure, there have been few applications and randomized controlled trials to confirm it in orthopedics. This study aims to develop a 3D interactive software system for teaching acetabular fracture classification and evaluate its efficacy. Participants were randomly but evenly allocated into either the experimental group (who learned the acetabular fracture classification using a 3D software) or the control group (who used a traditional two-dimensional [2D] tutorial). Both groups were then tasked to classify 10 acetabular fractures and complete a five-point Likert scale on their satisfaction of each learning modality. To calculate significance (< 0.05), independent t-test was used for normally distributed data whereas Mann-Whitney U test for non-normally distributed data. The experimental group significantly outperformed the control group (t (28) = 2.526, P = 0.017) with identifying correct acetabular fracture classification. Moreover, Likert scale score in the experimental group was also significantly higher than in the control group (Z = 2.477, P = 0.013). This 3D classification software has objectively and subjectively showed an advantage over the traditional 2D tutorial, resulting in an improved classification accuracy and higher Likert scale score. The 3D software has the potential to improve both clinical knowledge as well as identifying correct patient management in orthopedics.  相似文献

While time spent on anatomical education in medical school curricula has been diminishing over the last decades, the recognized role of anatomical dissection has expanded. It is perceived by many students and faculty not only as the means of learning the structure and function of the human body, but also as an opportunity for the acquisition of professional competencies such as team work, patient–doctor interaction, medical epistemology, self-awareness, and an understanding of medical ethics. This viewpoint article proposes that this learning process can be supported effectively through studying examples from the history of anatomy, as insights from this history can help illuminate contemporary ethical issues in anatomy and medicine. Anatomical education can thus provide not only the opportunity of gaining awareness of ethical questions, but also a chance to practice these new insights within the protected environment of the laboratories, in interaction with the dead and the living. Consequently, a new role has developed for anatomists, which includes the interweaving of the scholarly exploration of the history and ethics of anatomy with the practical application of research results into a reframed concept of anatomical education. Anatomy, as a foundational discipline in the medical curriculum, can thus provide a first step on the educational path of empathetic and humane medical caregivers.  相似文献

While most German anatomy institutes provide only limited information about body donors and their lives, students have expressed a desire to learn more about these individuals, especially about their motivations to donate their bodies for the sake of medical education. In order to gratify this wish, as well as to further humanize body donors, an educational film was compiled, and a study designed to capture the film's effects on medical students. This is the first study using standardized, validated psychological tools to evaluate the impact of an educational film about body donors on students’ empathy and psychological stress levels. The study followed a longitudinal, controlled, and cluster randomized design, including 77 (48 females/29 males) participants who watched the video either before, midway, or after the dissection course. Questionnaires were completed at four points in time applying the Jefferson Scale for Empathy (JSPE-S) and the Interpersonal Reactivity Index (IRI) to measure empathy. Psychological stress levels were recorded by the Brief Symptom Inventory (BSI). Overall, students recommended the film to be shown to all students (median 6.0; maximum on the six-point Likert scale). Viewing the film revealed no significant changes between study groups or over time in JSPE-S sum scores. All groups demonstrated a significant reduction of BSI values before the dissection course actually started and increased values during the course, but both developments appeared not to be associated with the intervention. Overall, the educational film did not correlate with any negative effects on students’ empathy and psychological stress levels, and it was strongly approved of by students, as it provided more humanizing personal information about body donors without violating their anonymity.  相似文献

The University of Oklahoma College of Medicine has conducted an annual Anatomical Donor Luncheon where families of the anatomical donors met anatomy dissection groups of medical students. The luncheon presented an opportunity for donor family members to share the life story of their loved one with the medical students prior to the start of the anatomy course. This study was designed to understand the impact of the Anatomical Donor Luncheon on families of the donors. Seven families in two different focus groups were included to explore the reactions and attitudes of the donor families to meeting the medical students. Conversations were digitally recorded and transcribed. Qualitative analysis of textual data were coded by three investigators using the Constant Comparative Method. To provide evidence of validity, a form of member checking was utilized. For further triangulation, an analyst not involved in conducting the focus groups or analyzing the data, re-coded all data. This analyst used categories and themes identified by the original analysts, ensuring validity of the themes and any negative cases (data not supporting or contradictory of the established categories and themes). One meta-theme and three sub-themes were identified. The meta-theme was Donor Family Participants Experience Transformation and Closure, and sub-themes were Motivators for Participation, Optimal Venue Factors, and Optimal Medical Student–Anatomical Donor Family Interactions. Study findings indicated the Anatomical Donor Luncheon facilitated closure on the death of their loved one, and transformed their apprehension about the luncheon and body donation into an attitude of gratitude and appreciation.  相似文献

While case-based discussions can empower students to apply knowledge to contextual clinical situations, scheduling these activities is a challenge in crowded curricula. Case-based eLearning activities, derived from existing cases discussed within anatomy small group tutorials, were created incorporating principles such as interactivity, reinforcement, and feedback. Over half of the students accessed one or more of these online cases, with 18% accessing all eight online cases provided. Access increased as the semester progressed, particularly just before summative examinations, implying students used these primarily as revision aides. Students rated both formats highly, but favored the online format with regard to enjoyment (P = 0.048), learning (P = 0.101), and feedback (P = 0.086). However, more students discussed these cases in small group tutorials within the anatomy dissecting room than completed them online (122 vs. 67) and themes emerging from free text comments included a desire to have more time dedicated to these cases during small group tutorials, and an appreciation for the opportunity for discussion with staff and learning through doing. Additionally, native English speakers rated the anatomy room discussions significantly higher in all aspects than non-native English speakers, suggesting that non-native speakers may be hesitant or reluctant to fully participate in front of peers. While online case-based learning activities are a useful adjunct to anatomy teaching, particularly for revision, assumptions that “digital natives” have an innate preference for digital resources require critical evaluation, as students still place a high value on opportunities for discussion with staff during their studies.  相似文献

Education research is increasingly being recognized as a legitimate route for faculty development in universities. However, many anatomy faculty lack the appropriate training and access to experienced mentors who can help them develop their own education research projects. Inspired by the American Physiological Society’s Institute for Teaching and Learning, the coauthors proposed and developed the inaugural Anatomy Education Research Institute (AERI 2017). Funded by an American Association of Anatomists Innovations grant, the five-day institute was held in Bloomington, Indiana in July 2017. The coauthors spent two years preparing the conference schedule, inviting speakers who could discuss education research topics and mentor applicants, reviewing applications, developing assessment instruments for the institute, and hosting the institute. A total of 62 registered participants (applicants and invited speakers) attended AERI 2017. Through a series of presentations and workshops, participants were introduced to many aspects of education research and the Scholarship of Teaching and Learning, including developing rigorous education research questions, determining appropriate methods to assess these questions, and searching the education research literature. Each day also included regular time devoted to work on their own education research project with help from more experienced mentors. Throughout the conference, participants were encouraged to post information on Twitter, using the hashtag #AERI2017. Participants had strong positive impressions of the conference and strongly requested future AERI conferences be held. Follow-up analyses will assess the institute in alignment with Kirkpatrick’s Four Levels of Evaluation Model, though preliminary evaluation indicates AERI 2017 met the original aims of the proposal.  相似文献
