Virtual reality laparoscopic simulator: Training tool for surgical trainee in Malaysia

Use of Innovative Technology in Surgical Training in Resource-Limited Settings: A Scoping Review

BACKGROUND

There has been a rapid growth in interest in global surgery. This increased commitment to improving global surgical care, however, has not translated into an equal exchange of surgical information between high-income countries (HICs) and low-income countries (LMICs). In recent years, a greater emphasis has been placed on training local medical personnel in order to increase surgical capacity while simultaneously decreasing reliance on expatriate visitors. Virtual curricular models, simulators, and immersive technologies have been developed and implemented in order to maximize training opportunities in low-resource settings. This study aims to assess and summarize innovative technologies used for surgical training in low-resource settings.

METHODS

We conducted a scoping review of the literature from 2000 to 2021. We included both academic and grey literature on surgical education technologies. Searches were performed on Medline and Embase as well as on Google, iOS, and Android app stores.

RESULTS

Four main categories of surgical training platforms were identified: web-based platforms, app-based platforms, virtual and augmented reality, and simulation. The platforms were analyzed based on their content, effectiveness, cost, accessibility, and barriers to use.

CONCLUSIONS

Virtual learning platforms show potential in surgical training as they are easily accessible, not limited by geography, continuously updated, and evaluated for effectiveness. In order to provide access to educational resources for surgical trainees all around the world, particularly in low-resource settings, increased effort and resources should be dedicated to developing free, open-access surgical training programs . Doing so will promote sustainable and equitable development in global surgical care.

How, for Whom, and in Which Contexts or Conditions Augmented and Virtual Reality Training Works in Upskilling Health Care Workers: Realist Synthesis

Background

Using traditional simulators (eg, cadavers, animals, or actors) to upskill health workers is becoming less common because of ethical issues, commitment to patient safety, and cost and resource restrictions. Virtual reality (VR) and augmented reality (AR) may help to overcome these barriers. However, their effectiveness is often contested and poorly understood and warrants further investigation.

Objective

The aim of this review is to develop, test, and refine an evidence-informed program theory on how, for whom, and to what extent training using AR or VR works for upskilling health care workers and to understand what facilitates or constrains their implementation and maintenance.

Methods

We conducted a realist synthesis using the following 3-step process: theory elicitation, theory testing, and theory refinement. We first searched 7 databases and 11 practitioner journals for literature on AR or VR used to train health care staff. In total, 80 papers were identified, and information regarding context-mechanism-outcome (CMO) was extracted. We conducted a narrative synthesis to form an initial program theory comprising of CMO configurations. To refine and test this theory, we identified empirical studies through a second search of the same databases used in the first search. We used the Mixed Methods Appraisal Tool to assess the quality of the studies and to determine our confidence in each CMO configuration.

Results

Of the 41 CMO configurations identified, we had moderate to high confidence in 9 (22%) based on 46 empirical studies reporting on VR, AR, or mixed simulation training programs. These stated that realistic (high-fidelity) simulations trigger perceptions of realism, easier visualization of patient anatomy, and an interactive experience, which result in increased learner satisfaction and more effective learning. Immersive VR or AR engages learners in deep immersion and improves learning and skill performance. When transferable skills and knowledge are taught using VR or AR, skills are enhanced and practiced in a safe environment, leading to knowledge and skill transfer to clinical practice. Finally, for novices, VR or AR enables repeated practice, resulting in technical proficiency, skill acquisition, and improved performance. The most common barriers to implementation were up-front costs, negative attitudes and experiences (ie, cybersickness), developmental and logistical considerations, and the complexity of creating a curriculum. Facilitating factors included decreasing costs through commercialization, increasing the cost-effectiveness of training, a cultural shift toward acceptance, access to training, and leadership and collaboration.

Conclusions

Technical and nontechnical skills training programs using AR or VR for health care staff may trigger perceptions of realism and deep immersion and enable easier visualization, interactivity, enhanced skills, and repeated practice in a safe environment. This may improve skills and increase learning, knowledge, and learner satisfaction. The future testing of these mechanisms using hypothesis-driven approaches is required. Research is also required to explore implementation considerations.

Virtual Reality Usability and Accessibility for Cultural Heritage Practices: Challenges Mapping and Recommendations

In recent years, virtual reality (VR) is at its maturity level for real practical exercises amongst many fields of studies, especially in the virtual walkthrough exploration system of cultural heritage (CH). However, this study remains scattered and limited. This work presents a systematic review that maps out the usability and accessibility issues that are challenging in using VR in CH. We identified 45 challenges that are mapped into five problem groups: system design, development process, technology, assessment process and knowledge transfer. This mapping is then used to propose 58 recommendations to improve the usability and accessibility of VR in CH that are categorized in three different recommendation groups namely, discovery and planning, design and development, and finally the assessment factors. This analysis identified the persistence in certain accessibility and usability problems such as there is a limit in navigating the view and space that constraint the users’ free movement and the navigation control is not ideal with the keyboard arrow button. This work is important because it provides an overview of usability and accessibility based challenges that are faced in applying, developing, deploying and assessing VR in the usage of digitalizing CH and proposed a great number of constructive recommendations to guide future studies. The main contribution of this paper is the mapping of usability and accessibility challenges into categories and the development of recommendations based on the identified problems.
