Abstract Background Video-based teaching has been part of medical education for some time but 360° videos using a virtual reality (VR) device are a new medium that offer extended possibilities. We investigated whether adding a 360° VR video to the internship curriculum leads to an improvement of long-term recall of specific knowledge on a gentle Caesarean Sections (gCS) and on general obstetric knowledge. Methods Two weeks prior to their Obstetrics and Gynaecology (O&G) internship, medical students were divided in teaching groups, that did or did not have access to a VR-video of a gCS. Six weeks after their O&G internship, potentially having observed one or multiple real-life CSs, knowledge on the gCS was assessed with an open questionnaire, and knowledge on general obstetrics with a multiple-choice questionnaire. Furthermore we assessed experienced anxiety during in-person attendance of CSs, and we asked whether the interns would have wanted to attend more CSs in-person. The 360° VR video group was questioned about their experience directly after they watched the video. We used linear regression analyses to determine significant effects on outcomes. Results A total of 89 medical students participated, 41 in the 360° VR video group and 48 in the conventional study group. Watching the 360° VR video did not result in a difference in either specific or general knowledge retention between the intervention group and the conventional study group. This was both true for the grade received for the internship, the open-ended questions as well as the multiple-choice questions and this did not change after adjustment for confounding factors. Still, 83.4% of the 360° VR video-group reported that more videos should be used in training to prepare for surgical procedures. In the 360° VR video-group 56.7% reported side effects like nausea or dizziness. After adjustment for the number of attended CSs during the practical internship, students in the 360° VR video-group stated less often (p = 0.04) that they would have liked to attend more CSs in-person as compared to the conventional study group. Conclusion Even though the use of 360° VR video did not increase knowledge, it did offer a potential alternative for attending a CS in-person and a new way to prepare the students for their first operating room experiences.

BACKGROUND There remain doubts about whether multiple choice answer formats (single choice) offer the best option to encourage deep learning or whether SC formats simply lead to superficial learning or cramming. Moreover, cueing is always a drawback in the SC format. Another way to assess knowledge is true multiple-choice questions in which one or more answers can be true and the student is not aware of how many true answers are to be anticipated (K´ or Kprime question format). OBJECTIVE Here, we compared both single-choice answers (one true answer, SC) with Kprime answers (one to four true answers out of four answers, Kprime) for the very same learning objectives in a study of pharmacology in medical students. METHODS Two groups of medical students were randomly subjected to a formative online test: group A) was first given 15 SC (#1-15) followed by 15 different Kprime questions (#16-30). The opposite design was used for group B. RESULTS The mean number of right answers was higher for SC than for Kprime questions in group A (10.02 vs. 8.63, p < 0.05) and group B (9.98 vs. 6.66, p < 0.05). The number of right answers was higher for nine questions of SC compared to Kprime in group A and for eight questions in group B (pairwise T-Test, p < 0.05). Thus, SC is easier to answer than the same learning objectives in pharmacology given as Kprime questions. One year later, four groups were formed from the previous two groups and were again given the same online test but in a different order: the main result was that all students fared better in the second test than in the initial test; however, the gain in points was highest if initially mode B was given. CONCLUSIONS Kprime is less popular with students being more demanding, but could improve memory of subject matter and thus might be more often used by meidcal educators.

BackgroundMusculoskeletal (MSK) complaints comprise a large proportion of outpatient visits. However, multiple studies show that medical school curriculum often fails to adequately prepare graduates to diagnose and manage common MSK problems. Current standardised exams inadequately assess trainees’ MSK knowledge and other MSK-specific exams such as Freedman and Bernstein’s (1998) exam have limitations in implementation. We propose a new 30-question multiple choice exam for graduating medical students and primary care residents. Results highlight individual deficiencies and identify areas for curriculum improvement.Methods/ResultsWe developed a bank of multiple choice questions based on 10 critical topics in MSK medicine. The questions were validated with subject-matter experts (SMEs) using a modified Delphi method to obtain consensus on the importance of each question. Based on the SME input, we compiled 30 questions in the assessment. Results of the large-scale pilot test (167 post-clerkship medical students) were an average score of 74 % (range 53% – 90 %, SD 7.8%). In addition, the tool contains detailed explanations and references were created for each question to allow an individual or group to review and enhance learning.SummaryThe proposed MSK30 exam evaluates clinically important topics and offers an assessment tool for clinical MSK knowledge of medical students and residents. It fills a gap in current curriculum and improves on previous MSK-specific assessments through better clinical relevance and consistent grading. Educators can use the results of the exam to guide curriculum development and individual education.

Abstract Background In the last few decades, the need to change the curriculum of basic medical science has been further emphasized. The purpose of this study was to evaluate the effects of teaching integrated course of physical examination and radiological anatomy in practical limb anatomy on medical students’ learning outcomes. Methods This was an experimental study. Medical students (of the 4th semester of medical education) were divided into intervention and control groups. Related topics of physical examination and radiological anatomy were added to the practical limb anatomy courses of the intervention group. Practical knowledge of anatomy, clinical applications of anatomical knowledge, students ‘satisfaction, and students’ attitude toward the anatomy course were assessed at the end of the study. Knowledge retention was assessed three months after the semester. Results The intervention group scored significantly higher mean scores in practical knowledge of anatomy test, clinical applications of anatomical knowledge test and knowledge retention test (P-value < 0.05). In evaluating students’ satisfaction with the course, the intervention group was satisfied with the course and teacher performance and had appropriate attitude (Mean˃4, Max score = 5) towards the application of anatomy in medicine. Conclusions The findings of this study showed that teaching practical anatomy with a clinical integrated approach can improve the practical knowledge of anatomy, knowledge retention, and clinical applications of anatomical knowledge. In addition, an integrated approach was associated with greater student satisfaction and it makes students have appropriate attitude towards the application of anatomy in medicine.

BACKGROUND History taking and physical examination (H&P) is an important core competency of undergraduate medical education. Recent advances in virtual reality (VR) simulation, lowering the complexity of learning tasks and the cognitive load of the learners, make this novel technology well suited for the initial training of novices. Reduced heart rate variation (HRV) is associated with decreased cognitive efficiency. Whether a 360° VR video review can impact learning outcome, cognitive load, and HRV while learning H&P skills in undergraduate medical students is unknown. OBJECTIVE We explored the effectiveness of 360° VR versus 2-dimensional (2D) video review to learn H&P skills with regards to learning outcome, cognitive load, and HRV. METHODS In 2018, we randomly assigned (1:1) 64 undergraduate medical students to either a 360° VR or 2D video group (matched by age, sex, and cognitive style) with allocation concealment to learn H&P skills using VR headsets and controllers. Subsequently, the participants each performed a focused H&P with a real outpatient. Two raters used the Mini-Clinical Evaluation Exercise (Mini-CEX) and Direct Observation of Procedural Skills (DOPS) questionnaires to assess the participants’ performance blindly. The Cognitive Load Component questionnaire and a portable electrocardiogram monitor were used to measure cognitive load and HRV, respectively. RESULTS All participants completed the study (mean age=24.2 years, standard deviation=0.9 years; 44 [69%] males and 20 [31%] females). The physical examination and student’s satisfaction scores (Mini-CEX), total DOPS score, total and intrinsic cognitive load scores, and standard deviation of normal to normal R-R intervals in the 360° VR video group were significantly higher than those in the 2D video group (effect size=0.63, 0.56, 0.72, 0.53, 0.67, and 0.52, respectively). Differences in the other aspects of the Mini-CEX and cognitive loads of both groups were not statistically significant. CONCLUSIONS This study provides a high level of evidence to confirm that 360° VR video review can help undergraduate medical students to perform fundamental H&P skills as effectively as traditional 2D video review. Furthermore, a 360° VR video review could be used to more efficiently examine the body of a real patient with higher learner’s satisfaction. These findings may inspire the design of 360° VR video-based training protocols to enhance competencies other than history taking.
