Augmented and virtual reality in anatomy education: Can they be effective if they do not provide immersive experience?

A new approach to peripheral nerve block education with the Anatomage Table as a learning adjunct

Human anatomy education serves as a gateway for entering the intricacies of health science. Human cadavers have been the gold standard for learning regional and gross anatomy. However, increasing barriers in acquisition, maintenance, and longevity have pushed anatomy education toward technology-based alternatives such as the Anatomage Table (AT), an interactive, life-sized virtual dissection table with many anatomy education-centric features. The AT has found purchase in various contexts, such as clinical settings, research, outreach, and education. Studies into the efficacy of the AT in teaching settings have been generally positive but limited in its application, particularly in clinical procedure education. In this study, we conducted an informal workshop for second-year Certified Registered Nurse Anesthetist (CRNA) students to aid in being able to identify the important neuraxial landmarks for performing peripheral nerve blocks (PNBs), an anesthetic technique often used before other procedures. In our workshop, we paired the AT with identification of the same neuraxial landmarks on volunteer models with an ultrasound probe to provide students with relevant tactile experience for the procedure. From our pre-/post-surveys of the participants (n = 29), we found that our workshop significantly increased student confidence in identifying the relevant neuraxial landmarks for and in performing PNBs. Our results support the use of the AT in clinical education as a supplement, particularly where other anatomic teaching tools, such as cadaver models, may be too difficult to implement.NEW & NOTEWORTHY We implemented the Anatomage Table (AT) and portable ultrasound to teach neuraxial landmarks for performing peripheral nerve blocks (PNB), an anesthetic technique for Certified Registered Nurse Anesthetist (CRNA) students.

Use of photogrammetry-based digital models in anatomy education: An overview

PURPOSE

Photogrammetry is a technique which includes taking multiple digital photographs from various angles and using those photographs to create three-dimensional virtual models. We aimed to review the outcomes of the implementation of photogrammetry in anatomy education.

METHODS

We searched PubMed, Scopus and Cochrane library for studies with purpose to explore the outcomes of the use of photogrammetry-based digital models in anatomy teaching. From each included paper we extracted: authors, number of participants, anatomical region of interest, educational outcomes, and their level according to Kirkpatrick hierarchy.

RESULTS

Seven studies were included. Four of them concerned neuroanatomy and three of them concerned other systems. All studies comprised participants' perceptions about the educational intervention, while two of them also evaluated anatomical knowledge acquisition. Overall, the participants rated photogrammetry-based models very highly and preferred them to other teaching tools. These models were also shown able to significantly enhance the anatomical knowledge.

CONCLUSIONS

Photogrammetry-based digital objects seem to have a promising anatomy teaching potential. The value of these objects seems to be especially pertinent in teaching the relatively complex field of neuroanatomy. Further research may investigate the effectiveness of photogrammetry-based models in comparison with other anatomy education tools, and with other methods of creation of three-dimensional virtual objects.

Are We Facing the End of Gross Anatomy Teaching as We Have Known It for Centuries?

The status of anatomy education in undergraduate medical education has dramatically changed over the course of the past century. From the most important and time-consuming component of the preclinical program, anatomy education has reduced in size and status, and yielded in curricular space to accommodate other disciplines and topics. Meanwhile, radiology has become more prominent, as a means to visualize anatomy, not only in clinical care but also in education. For this perspective paper, the authors, all with backgrounds in anatomy, radiology and/or medical education, conducted structured conversations with several academic colleagues with similar backgrounds, reviewed pertinent literature and analyzed the causes of the historical decline of a knowledge domain of medical education, that nevertheless is widely considered essential for medical students and graduates. After this analysis, the authors propose four ways forward. These directions include systematic peer teaching and development of anatomy education as a scholarly domain, further vertical integration with postgraduate medical education, full integration with radiology education, and capitalizing on educational technology. Schools in several industrialized countries have made steps in these directions, which can be further strengthened. In less affluent countries, and in countries with curricula strongly determined by tradition, these steps are less easy to make. To respond to changes in global health and health care, combined with the inevitable technological progress, and international mobility, we believe all schools will move in these directions, slower or faster.

Are extended reality technologies (ERTs) more effective than traditional anatomy education methods?

PURPOSE

Reviews and meta-analyses concerning the effectiveness of extended reality technologies (ERTs) (namely virtual, augmented, and mixed reality-VR, AR, and MR) in anatomy education (AE) have resulted in conflicting outcomes. The current review explores the existing evidence provided by reviews of AE literature regarding the effectiveness of ERTs after their comparison with traditional (either cadaveric or two-dimensional) anatomy teaching modalities and sheds light on the factors associated with the conflicting outcomes.

METHODS

PubMed, SCOPUS, ERIC, and Cochrane databases were searched for review articles with the purpose to investigate the effectiveness of ERTs in AE.

RESULTS

Nine (four systematic with or without meta-analysis and five non-systematic) reviews were included. A lack of robust evidence provided by those reviews was noted, mainly due to a remarkable confusion in the definition of each ERT, along with confusion when authors referred to traditional AE (TAE) methods.

CONCLUSIONS

To clarify to what extent VR, AR, or MR can replace or supplement TAE methods, there is a primary need for addressing issues regarding the definition of each technology and determining which specific TAE methods are used as comparators.

Technological resources for teaching and learning about human anatomy in the medical course: Systematic review of literature

The consolidation of technology as an alternative strategy to cadaveric dissection for teaching anatomy in medical courses was accelerated by the recent Covid-19 pandemic, which caused the need for social distance policies and the closure of laboratories and classrooms. Consequently, new technologies were created, and those already been developed started to be better explored. However, information about many of these instruments and resources is not available to anatomy teachers. This systematic review presents the technological means for teaching and learning about human anatomy developed and applied in medical courses in the last ten years, besides the infrastructure necessary to use them. Studies in English, Portuguese, and Spanish were searched in MEDLINE, Scopus, ERIC, LILACS, and SciELO databases, initially resulting in a total of 875 identified articles, from which 102 were included in the analysis. They were classified according to the type of technology used: three-dimensional (3D) printing (n = 22), extended reality (n = 49), digital tools (n = 23), and other technological resources (n = 8). It was made a detailed description of technologies, including the stage of the medical curriculum in which it was applied, the infrastructure utilized, and which contents were covered. The analysis shows that between all technologies, those related to the internet and 3D printing are the most applicable, both in student learning and the financial cost necessary for its structural implementation.

One year of anatomy teaching and learning in the outbreak: Has the Covid-19 pandemic marked the end of a century-old practice? A systematic review

At the end of 2019, the Covid-19 pandemic spread caused restrictions in business and social spheres. Higher education was also severely affected: universities and medical schools moved online to distance learning and laboratory facilities closed. Questions arise about the long-term effects of this pandemic on anatomical education. In this systematic review, the authors investigated whether or not anatomical educators were able to deliver anatomical knowledge during this pandemic. They also discuss the challenges that anatomical education has faced over the last year. The search strategy was conducted between July 2020 and July 2021. Two hundred and one records were identified, and a total of 79 studies were finally included. How best to deliver anatomy to students remains a moot point. In the last years, the advent of new technologies has raised the question of the possible overcoming of dissection as the main instrument in anatomical education. The Covid-19 pandemic further sharpened the debate. Remote learning enhanced the use of technologies other than cadaveric dissection to teach anatomy. Moreover, from the analyzed records it appears that both from students' perspective as well as teachers' there is a clear tear between those who endorse dissection and those who believe it could be easily overcome or at least integrated by virtual reality and online learning. The authors strongly believe that the best anatomy teaching practice requires the careful adaptation of resources and methods. Nevertheless, they support cadaveric dissection and hope that it will not be replaced entirely as a result of this pandemic.
