Neurosurgical Education Using Cadaver-Free Brain Models and Augmented Reality: First Experiences from a Hands-On Simulation Course for Medical Students.

Background and Objectives: Neurosurgery has been underrepresented in the medical school curriculum. Advances in augmented reality and 3D printing have opened the way for early practical training through simulations. We assessed the usability of the UpSurgeOn simulation-based training model and report first experiences from a hands-on neurosurgery course for medical students. Materials and Methods: We organized a two-day microneurosurgery simulation course tailored to medical students. On day one, three neurosurgeons demonstrated anatomical explorations with the help of life-like physical simulators (BrainBox, UpSurgeOn). The surgical field was projected onto large high-definition screens by a robotic-assisted exoscope (RoboticScope, BHS Technologies). On day two, the students were equipped with microsurgical instruments to explore the surgical anatomy of the pterional, temporal and endoscopic retrosigmoid approaches. With the help of the RoboticScope, they simulated five clipping procedures using the Aneurysm BrainBox. All medical students filled out a digital Likert-scale-based questionnaire to evaluate their experiences. Results: Sixteen medical students participated in the course. No medical students had previous experience with UpSurgeOn. All participants agreed that the app helped develop anatomical orientation. They unanimously agreed that this model should be part of residency training. Fourteen out of sixteen students felt that the course solidified their decision to pursue neurosurgery. The same fourteen students rated their learning experience as totally positive, and the remaining two rated it as rather positive. Conclusions: The UpSurgeOn educational app and cadaver-free models were perceived as usable and effective tools for the hands-on neuroanatomy and neurosurgery teaching of medical students. Comparative studies may help measure the long-term benefits of UpSurgeOn-assisted teaching over conventional resources.

A Needs-Based Analysis of Teaching on Vaccinations and COVID-19 in German Medical Schools.

The COVID-19 pandemic highlights the need for improving public confidence in vaccines. Academic gaps and redundancies on vaccinations must be identified to revise the medical curriculum for up-to-date training of medical students. This cross-sectional survey assessed the status of vaccine-related teaching in general and specific to COVID-19 in medical schools across Germany. A total of 4313 medical students completed a questionnaire comprising items on national learning goals and perceived needs for teaching on vaccinations. Mixed methods were used to analyse data quantitatively for relative frequencies (%) and correlations between teaching items and semesters (Spearman's rho), and qualitatively (content analysis). Our findings showed that 38.92% of the students were dissatisfied with teaching on vaccine-preventable diseases, but the perceived satisfaction increased in later semesters (r = 0.46, p < 0.001). Moreover, 75.84% and 68.15% of the students were dissatisfied with teaching related to vaccine scepticism and vaccine-related communication strategies, respectively. Furthermore, 63.79% reported dissatisfaction with teaching on COVID-19 disease and 72.93% with teaching on COVID-19 vaccines. A total of 79.12% stated they educated others on COVID-19 and its vaccines and 75.14% felt responsible to do so. A majority of the medical students were dissatisfied with teaching on dealing with vaccine scepticism, communication strategies and COVID-19 vaccines. We recommend practice-oriented vaccine education, especially for teaching communication skills to medical students.
