Use of 360° virtual reality video in medical obstetrical education: a quasi-experimental design

Collaborative 360° virtual reality training of medical students in clinical examinations

Simulation-based training in computer-generated environments has always played an important role in clinical medical education. Recently, there has been a growing interest in using 360° videos of real-life situations for training in health professions. Several studies report positive results from using 360° Virtual Reality for individuals, yet there are currently no studies on collaborative 360° Virtual Reality training. In this paper, we evaluate how 360° Virtual Reality can support collaborative training in clinical medical education. The study population consisted of 14 medical students in semester 5 of their Bachelor's programme. The students were divided into three groups before watching and annotating a 360° video of an authentic learning situation inside a collaborative immersive virtual reality space. The original video shows a problem-based examination of the collateral and cruciate ligaments of the knee performed by students under the supervision of a professor. After training in collaborative 360° Virtual Reality, students then had to perform the same tests in a physical examination. The students' performance was subsequently evaluated by a professor with expertise in knee examinations. The results show that 12 out of 14 students received a score of 2 for one or more tests, thereby meeting the required learning objective. One student received a score of 1 and one student did not perform any of the tests. The students actively use the tools provided by the software and different communicative strategies when working collaboratively in 360° Virtual Reality, which enables them to perform the tests in the physical examination by transferring their constructed knowledge. The results indicate that our pedagogical design in collaborative immersive 360° Virtual Reality can become a relevant addition to face-to-face clinical medical training.

Face-to-face versus 360° VR video: a comparative study of two teaching methods in nursing education

BACKGROUND

The practical sessions during skills laboratory simulation or clinical simulation are cores of nursing education. For this, different modalities have been devised to facilitate psychomotor skills learning. One of the commonly used educational material or instructional method to supplement skills learning across various disciplines is video-based teaching method. The opportunities of traditional two-dimensional video might be limitless and maximized with 360º virtual reality (VR) video, which offers immersive experience. This study incorporates 360º VR video into skills laboratory training as an alternative approach to face-to-face procedure demonstration.

METHODS

An open-label, parallel (1:1), randomized controlled trial study was conducted among third-year undergraduate nursing students at Hiroshima University, Japan. The nursing students were block-randomized into 360º VR video and face-to-face demonstration group. After a 3-hour theoretical class of patient management on ventilator and closed-suction principles of mechanically ventilated patients in an Intensive Care Unit focused class, the 360º VR group watched the 360º VR video of closed tracheal suction (including oral) using the head-mounted display of Meta Quest 2 individually, while the face-to-face group attended the instructor's demonstration. A week after the skills laboratory, the students' psychomotor skills, knowledge, satisfaction, confidence were evaluated; the 360º VR video group's perception was explored; Wilcoxon rank-sum test was used to compare the two groups.

RESULTS

A total of 57 students were analyzed; 27 students in the 360º VR video group and 30 students in face-to-face group. There were no statistically significant differences between both groups in skills, knowledge, and confidence. However, the face-to-face group had higher satisfaction level than the 360º VR group; this difference was statistically significant. In the 360º VR video group, 62% agreed that VR makes learning more interesting; more than half of students (62.5%) experienced VR sickness symptoms, and "feeling of drunk" is the highest. The students appreciated the ready to use, immersiveness, and realism; however, symptoms and discomfort, burdensomeness, and production limitations were improvements recommended.

CONCLUSION

Although face-to-face demonstration is the established method of teaching psychomotor skills to nursing students, the use of 360º VR video could achieve similar learning effect as an alternative approach.

The virtual reality classroom: a randomized control trial of medical student knowledge of postpartum hemorrhage emergency management

Objective

To investigate the use of a virtual reality learning environment (VRLE) to enhance medical student knowledge of postpartum hemorrhage (PPH) emergency management and insertion of a postpartum balloon.

Methods

A randomized control trial involving medical students from University College Dublin, Ireland. Participants were randomly allocated to the intervention group (VRLE tutorial) or control group (PowerPoint tutorial on the same topic). All participants completed pre-learning experience and post-learning experience surveys. Both groups were timed and assessed on postpartum balloon insertion technique on a model pelvis. The primary outcome was assessment of student knowledge. Secondary outcomes included confidence levels, time taken to complete the task, technique assessment, satisfaction with the learning environment, and side effects of VR.

Results

Both learning experiences significantly (p < 0.001) enhanced student performance on the post-learning experience multiple choice questionnaire, with no difference between the intervention and control groups. In the intervention group, time for task completion was significantly less compared to the control group (1-2 min vs. 2-3 min, p = 0.039). Both learning experiences significantly (p < 0.001) enhanced student confidence, with no significant difference between intervention and control groups. 100% of the students using the VRLE enjoyed the experience, and 82.4% were very likely to recommend use of VRLE in medical education. 94.1% of the students felt the VRLE was beneficial over didactic teaching.

Conclusion

Receiving formal instruction, regardless of format, enhances students' knowledge and confidence of the topic covered. Students who received instruction via the VRLE assembled the postpartum balloon faster than students who received didactic teaching. VR may be beneficial in teaching hands-on procedural skills in obstetrics and gynecology education.

Evaluation of a Virtual Reality-Based Open Educational Resource Software

OBJECTIVES

Virtual reality (VR) teaching methods have potential to support medical students acquire increasing amounts of knowledge. EVENT (Easy VR EducatioN Tool) is an open educational resource software for immersive VR environments, which is designed for use without programming skills. In this work, EVENT was used in a medical student VR course on pancreatic cancer.

METHODS

Medical students were invited to participate in the course. Before and after VR simulation, participants completed a multiple-choice knowledge assessment, with a maximum score of 10, and a VR experience questionnaire. The primary endpoint compared pre- and post-VR simulation test scores. Secondary endpoints included usability and factors that could affect learning growth and test results.

RESULTS

Data from 117 of the 135 participating students was available for analysis. Student test scores improved by an average of 3.4 points (95% CI 3.1-3.7, P < 0.001) after VR course. The secondary endpoints of gender, age, prior knowledge regarding the medical subject, professional training completed in the medical field, video game play, three-dimensional imagination skills, or cyber-sickness had no major impact on test scores or final ranking (top or bottom 25%). The 27 students whose post-VR simulation test scores ranked in the top 25% had no prior experience with VR. The average System Usability Scale score was 86.1, which corresponds to an excellent outcome for user-friendliness. Questionnaire responses post-VR simulation show students (81.2% [95/117]) interest in more VR options in medical school.

CONCLUSIONS

We present a freely available software that allows for the development of VR teaching lessons without programming skills.

Comparing the influence of big data resources on medical knowledge recall for staff with and without medical collaboration platform

BACKGROUND

This study aims to examine how big data resources affect the recall of prior medical knowledge by healthcare professionals, and how this differs in environments with and without remote consultation platforms.

METHOD

This study investigated two distinct categories of medical institutions, namely 132 medical institutions with platforms, and 176 medical institutions without the platforms. Big data resources are categorized into two levels-medical institutional level and public level-and three types, namely data, technology, and services. The data are analyzed using SmartPLS2.

RESULTS

(1) In both scenarios, shared big data resources at the public level have a significant direct impact on the recall of prior medical knowledge. However, there is a significant difference in the direct impact of big data resources at the institutional level in both scenarios. (2) In institutions with platforms, for the three big data resources (the medical big data assets and big data deployment technical capacity at the medical institutional level, and policies of medical big data at the public level) without direct impacts, there exist three indirect pathways. (3) In institutions without platforms, for the two big data resources (the service capability and big data technical capacity at the medical institutional level) without direct impacts, there exist three indirect pathways.

CONCLUSIONS

The different interactions between big data, technology, and services, as well as between different levels of big data resources, affect the way clinical doctors recall relevant medical knowledge. These interaction patterns vary between institutions with and without platforms. This study provides a reference for governments and institutions to design big data environments for improving clinical capabilities.

Come and see through my eyes: A systematic review of 360-degree video technology in nursing education

OBJECTIVES

Viewers can watch 360-degree videos from any angle, like a panorama, and experience the virtual environment directly. Recently, there has been a growing interest in immersive and interactive technologies in education, and the use of 360-degree videos has become popular. This systematic review was conducted to present the current use of 360-degree videos in nursing education.

DESIGN

Systematic review.

DATA SOURCES

In addition to screening the Google Scholar, MEDLINE, SCOPUS, and EBSCO databases, we also performed hand searching.

REVIEW METHODS

Relevant keywords were used to identify trials published in the above-mentioned databases from inception to March 1, 2023. In the first step, the titles, abstracts, and full texts of the retrieved studies were independently reviewed by two authors according to the inclusion criteria. Studies on which there was disagreement were reviewed by all authors, and a consensus decision was reached. The data from the studies included in the review were analyzed and reported using the PRISMA 2020 checklist.

RESULTS

Twelve articles that met the inclusion criteria were reviewed. It was determined that 360-degree video scenarios used in nursing education were mostly related to mental health nursing, and the videos were mostly viewed through head-mounted displays, without any interactive features. Most difficulties encountered in the use of these videos were related to motion sickness. The main implications of the reviewed studies were that 360-degree videos contributed to the development of students' knowledge, skills, and attitudes and that the use of these videos was recommended.

CONCLUSIONS

As an innovative application the use of 360-degree videos in nursing education was examined from various perspectives in this review. The results showed that the use of such videos was convenient and effective for nursing education.

"We're going on a virtual trip!": a switching-replications experiment of 360-degree videos as a physical field trip alternative in primary education

Field trips are steadily declining due to limited funding, time constraints, safety concerns, and other logistical issues. Many schools are resorting to a virtual field trip (VFT), especially when education is disrupted due to public health concerns, natural disasters, or other unforeseen significant events. Virtual reality as a common form of VFT is likely not an option for many schools due to cost and other barriers. The purpose of our study was to explore the potential of going in a VFT using 360-degree (360°) videos as an alternative to a physical field trip in primary education. We recruited third-grade pupils (aged 8-9) from two private elementary schools to experience VFTs using 360° videos (360V) and regular videos (REGV). Using a switching-replications experimental design, we compared their content recall (assessment tests) and VFT experience (attitude, perceived usefulness, involvement, inquiry, video engagement, and virtual guide) across four-time points. Our results show that the increase in content recall scores of 360V groups after VFTs was consistently higher compared to REGV groups at all time points, although it was only significant in one quarter. We also found pupils' video engagement, involvement, and attitude as significant factors in their VFT experience. These results call attention to a possible implementation of VFTs and continue the long-standing tradition that has been acknowledged as a student-centered, interactive instructional method.

Application of problem-based learning combined with a virtual simulation training platform in clinical biochemistry teaching during the COVID-19 pandemic

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has had a great impact on the traditional teaching mode (Lecture-based Learning, LBL) and laboratory teaching. To address this challenge, the researchers conducted online Problem-based learning (PBL) teaching and virtual simulation laboratory teaching through DingTalk, and evaluated the effectiveness of this method in teaching clinical biochemistry.

METHODS

With the method of cluster sampling, the researchers randomly selected 60 students from two classes of the Class 2019 as the experimental group for this prospective experimental study. The theory class was taught online PBL through DingTalk, and experimental lectures were given by virtual simulation. After the experimental teaching, students were assessed for theory and operation. Self-administered questionnaires were administered through DingTalk. 65 students from our 2018 medical laboratory class were randomly selected as the control group, and offline LBL and traditional experimental teaching methods were used. Examination results were obtained through teaching portfolios.

RESULTS

The experimental group had significantly better examination scores in theoretical knowledge and experimental operational skills than the control group (87.45 ± 5.91 vs. 83.52 ± 9.94, P = 0.0095; 87.08 ± 12.42 vs. 80.18 ± 14.04, P = 0.0044). The results of the questionnaire survey revealed that the experimental group was more receptive to the DingTalk-PBL teaching method and virtual simulation laboratory teaching. Moreover, this hybrid teaching method was more effective in promoting basic knowledge understanding (95.0%, 57/60), facilitating the mastery of operational skills (93.3, 56/60), cultivating interest in learning (96.7%, 58/60), training clinical thinking (95.0%, 57/60), improving communication skills (95.0%, 57/60), and enhancing self-learning ability (91.7%, 55/60) and was more satisfying than traditional teaching method (all P < 0.05).

CONCLUSION

The DingTalk-based PBL method combined with virtual simulation experiments was an effective and acceptable teaching strategy during the pandemic compared with the traditional teaching method.

Learning from 360-degree film in healthcare simulation: a mixed methods pilot

Technology that delivers an immersive experience in education offers a viable alternative to in-person teaching. This study aims to compare learning from a clinical encounter viewed in a virtual reality 360-degree headset to that of a traditional monitor by quantifying the user experience and testing what was learnt. Furthermore, experiential learning is described as a key concept in simulation practice, and this is explored using transcripts of participants' experiences with 360-degree video. We could determine no statistical difference between median exam scores between groups (p = 0.25), and there was no correlation found between total immersion and motivational scores with exam performance (Rho = -0.14 p = 0.18, Rho = 0.08 p = 0.31). However, those viewing 360 media reported significantly higher immersion, motivation, and empathy scores (p < 0.05). Domains based upon Kolb's learning cycle generated themes including engagement, communication, and self-efficacy. 360 video creates an immersive experience with an associated high-value motivational position; however, this could not be translated to an increase in exam scores. There are benefits to perceived learning and emotional content with 360 videos, although, pedagogical theory needs further understanding if educators are to embed new immersive technology in curriculums.

360° 3D virtual reality operative video for the training of residents in neurosurgery

OBJECTIVE

Training of residents is an essential but time-consuming and costly task in the surgical disciplines. During the coronavirus disease 2019 pandemic, surgical education became even more challenging because of the reduced caseload due to the increased shift to corona care. In this context, augmented 360° 3D virtual reality (VR) videos of surgical procedures enable effective off-site training through virtual participation in the surgery. The goal of this study was to establish and evaluate 360° 3D VR operative videos for neurosurgical training.

METHODS

Using a 360° camera, the authors recorded three standard neurosurgical procedures: a lumbar discectomy, brain metastasis resection, and clipping of an aneurysm. Combined with the stereoscopic view of the surgical microscope, 7- to 10-minute 360° 3D VR videos augmented with annotations, overlays, and commentary were created. These videos were then presented to the neurosurgical residents at the authors’ institution using a head-mounted display. Before viewing the videos, the residents were asked to fill out a questionnaire indicating their VR experience and self-assessment of surgical skills regarding the specific procedure. After watching the videos, the residents completed another questionnaire to evaluate their quality and usefulness. The parameters were scaled with a 5-point Likert scale.

RESULTS

Twenty-two residents participated in this study. The mean years of experience of the participants in neurosurgery was 3.2 years, ranging from the 1st through the 7th year of training. Most participants (86.4%) had no or less than 15 minutes of VR experience. The overall quality of the videos was rated good to very good. Immersion, the feeling of being in the operating room, was high, and almost all participants (91%) stated that 360° VR videos provide a useful addition to the neurosurgical training. VR sickness was negligible in the cohort.

CONCLUSIONS

In this study, the authors demonstrated the feasibility and high acceptance of augmented 360° 3D VR videos in neurosurgical training. Augmentation of 360° videos with complementary and interactive content has the potential to effectively support trainees in acquiring conceptual knowledge. Further studies are necessary to investigate the effectiveness of their use in improving surgical skills.

Impact of big data resources on clinicians’ activation of prior medical knowledge

Background

Activating prior medical knowledge in diagnosis and treatment is an important basis for clinicians to improve their care ability. However, it has not been systematically explained whether and how various big data resources affect the activation of prior knowledge in the big data environment faced by clinicians.

Objective

The aim of this study is to contribute to a better understanding on how the activation of prior knowledge of clinicians is affected by a wide range of shared and private big data resources, to reveal the impact of big data resources on clinical competence and professional development of clinicians.

Method

Through the comprehensive analysis of extant research results, big data resources are classified as big data itself, big data technology and big data services at the public and institutional levels. A survey was conducted on clinicians and IT personnel in Chinese hospitals. A total of 616 surveys are completed, involving 308 medical institutions. Each medical institution includes a clinician and an IT personnel. SmartPLS version 2.0 software package was used to test the direct impact of big data resources on the activation of prior knowledge. We further analyze their indirect impact of those big data resources without direct impact.

Results

(1) Big data quality environment at the institutional level and the big data sharing environment at the public level directly affect activation of prior medical knowledge; (2) Big data service environment at the institutional level directly affects activation of prior medical knowledge; (3) Big data deployment environment at the institutional level and big data service environment at the public level have no direct impact on activation of prior knowledge of clinicians, but they have an indirect impact through big data quality environment and service environment at the institutional level and the big data sharing environment at the public level.

Conclusions

Big data technology, big data itself and big data service at the public level and institutional level interact and influence each other to activate prior medical knowledge. This study highlights the implications of big data resources on improvement of clinicians’ diagnosis and treatment ability.

Using virtual reality in lumbar puncture training improves students learning experience

BACKGROUND

Lumbar puncture (LP) is a commonly performed medical procedure in a wide range of indications. Virtual reality (VR) provides a stimulating, safe and efficient learning environment. We report the design and the evaluation of a three dimensions (3D) video for LP training.

METHODS

We recorded a stereoscopic 180-degrees 3D video from two LPs performed in clinical settings in Fernand Widal Lariboisière University Hospital, Paris, France. The video was administered to third-year medical students as well as to a residents and attendings group during LP simulation-based training sessions.

RESULTS

On 168 participants (108 novice third-year medical students, and 60 residents and attendings with prior LP experience), satisfaction after video exposure was high (rated 4.7 ± 0.6 on a 5-point scale). No significant discomfort was reported (comfort score graded 4.5 ± 0.8 on 5). LP-naive students displayed higher satisfaction and perceived benefit than users with prior LP experience (overall, P < 0.05). Trainees evaluated favorably the 3D feature and supported the development of similar tutorials for other medical procedures (respectively, 3.9 ± 1.1 and 4.4 ± 0.9 on 5).

CONCLUSION

We report our experience with a 3D video for LP training. VR support could increase knowledge retention and skill acquisition in association to LP simulation training.

Virtual Simulation in Undergraduate Medical Education: A Scoping Review of Recent Practice

Virtual simulation (VS) as an emerging interactive pedagogical strategy has been paid more and more attentions in the undergraduate medical education. Because of the fast development of modern computer simulation technologies, more and more advanced and emerging VS-based instructional practices are constantly increasing to promote medical education in diverse forms. In order to describe an overview of the current trends in VS-based medical teaching and learning, this scoping review presented a worldwide analysis of 92 recently published articles of VS in the undergraduate medical teaching and learning. The results indicated that 98% of included articles were from Europe, North America, and Asia, suggesting a possible inequity in digital medical education. Half (52%) studies reported the immersive virtual reality (VR) application. Evidence for educational effectiveness of VS in medical students’ knowledge or skills was sufficient as per Kirkpatrick’s model of outcome evaluation. Recently, VS has been widely integrated in surgical procedural training, emergency and pediatric emergency medicine training, teaching of basic medical sciences, medical radiation and imaging, puncture or catheterization training, interprofessional medical education, and other case-based learning experiences. Some challenges, such as accessibility of VS instructional resources, lack of infrastructure, “decoupling” users from reality, as well as how to increase students’ motivation and engagement, should be addressed.

Using 360-degree video for teaching emergency medicine during and beyond the COVID-19 pandemic

OBJECTIVE

During the COVID-19 pandemic, emergency medicine (EM) teachers had to employ innovative methods to ensure the continuity of the education process. The purpose of this study was to explore the adequacy of the 360-degree video (video 360) technology in EM education in the context of: (a) students' attitudes towards the video 360; (b) students' academic performance in their required examination at the end of the EM course compared to the assessment results of students from the previous academic year.

METHODS

A mixed-method research project enrolled the fourth-year medical students who attended the required EM course during the first semester of the academic year 2020-2021 when all activities with undergraduate students went online and teaching scenarios recorded in the video 360 format were employed. Data collection was two-fold: (a) anonymous questionnaires, complemented with basic YouTube analytics; (b) multiple-choice questionnaires (MCQ) and oral examination, contrasting the results with those in 2019-2020. Data analysis used descriptive statistics and non-parametric methods.

RESULTS

Seventy-nine students (53 females and 26 males) participated in the project and all completed the EM course. Students' interest in and their acceptance of the video 360 technology were high (total scoring in the upper 20% of the respective scales), with consistently good performance in two parallel, independent, interview-based oral/practical evaluations (Spearman correlation coefficient R = 0.665, p < .001). The majority scored over 90% in the summative MCQ, with higher values compared to their colleagues' during the previous academic year (with on-site teaching): scoring percentages with mean ± standard deviation of 92.52 ± 4.57 and 76.67 ± 18.77, respectively.

CONCLUSION

Our project showed that the video 360 scenarios were effective in teaching EM. In the long term, employing this accessible and inexpensive educational approach would add value to on-site training by enriching the exposure to a specific ED environment.KEY MESSAGESMedical students valued the 360-degree video scenarios as contributing substantially to their EM knowledge and preparedness.Examination results confirmed the 360-degree video scenarios as viable in EM teaching.The 360-degree video technology would be a sustainable solution for hybrid medical teaching in the long term.
