Neurosurgical simulation models developed in Latin America and the Caribbean: a scoping review

Simulation training is an educational tool that provides technical and cognitive proficiency in a risk-free environment. Several models have recently been presented in Latin America and the Caribbean (LAC). However, many of them were presented in non-indexed literature and not included in international reviews. This scoping review aims to describe the simulation models developed in LAC for neurosurgery training. Specifically, it focuses on assessing the models developed in LAC, the simulated neurosurgical procedures, the model's manufacturing costs, and the translational outcomes. Simulation models developed in LAC were considered, with no language or time restriction. Cadaveric, ex vivo, animal, synthetic, and virtual/augmented reality models were included for cranial and spinal procedures. We conducted a review according to the PRISMA-ScR, including international and regional reports from indexed and non-indexed literature. Two independent reviewers screened articles. Conflicts were resolved by a third reviewer using Covidence software. We collected data regarding the country of origin, recreated procedure, type of model, model validity, and manufacturing costs. Upon screening 917 studies, 69 models were developed in LAC. Most of them were developed in Brazil (49.28%). The most common procedures were related to general neurosurgery (20.29%), spine (17.39%), and ventricular neuroendoscopy and cerebrovascular (15.94% both). Synthetic models were the most frequent ones (38.98%). The manufacturing cost ranged from 4.00 to 2005.00 US Dollars. To our knowledge, this is the first scoping review about simulation models in LAC, setting the basis for future research studies. It depicts an increasing number of simulation models in the region, allowing a wide range of neurosurgical training in a resource-limited setting.

Integrating simulation into surgical training: a qualitative case study of a national programme

BACKGROUND

Applying simulation-based education (SBE) into surgical curricula is challenging and exacerbated by the absence of guidance on implementation processes. Empirical studies evaluating implementation of SBE interventions focus primarily on outcomes. However, understanding the processes involved in organising, planning, and delivering SBE adds knowledge on how best to develop, implement, and sustain surgical SBE. This study used a reform of early years surgical training to explore the implementation of a new SBE programme in Scotland. It aimed to understand the processes that are involved in the relative success (or failure) when implementing surgical SBE interventions.

METHODS

This qualitative case study, underpinned by social constructionism, used publicly available documents and the relevant surgical SBE literature to inform the research focus and contextualise data obtained from semi-structured interviews with core surgical trainees (n = 46), consultant surgeons (n = 25), and key leaders with roles in surgical training governance in Scotland (n = 7). Initial data coding and analysis were inductive. Secondary data analysis was then undertaken using Normalisation Process Theory (NPT). NPTs' four constructs (coherence, cognitive participation, collective action, reflexive monitoring) provided an explanatory framework for scrutinising how interventions are implemented, embedded, and integrated into practice, i.e. the "normalisation" process.

RESULTS

Distributed leadership (individual SBE initiatives assigned to faculty but overall programme overseen by a single leader) and the quality improvement practise of iterative refinement were identified as key novel processes promoting successful normalisation of the new SBE programme. Other processes widely described in the literature were also identified: stakeholder collaboration, personal contacts/relational processes, effective communication, faculty development, effective leadership, and tight programme management. The study also identified that learners valued SBE activities in group- or team-based social environments over isolated deliberate practice.

CONCLUSIONS

SBE is most effective when designed as a comprehensive programme aligned to the curriculum. Programmes incorporating both group-based and isolated SBE activities promote deliberate practice. Distributed leadership amongst faculty attracts wide engagement integral to SBE programme implementation, while iterative programme refinement through regular evaluation and action on feedback encourages integration into practice. The knowledge contributed by critically analysing SBE programme implementation processes can support development of much needed guidance in this area.

A look at the global impact of COVID-19 pandemic on neurosurgical services and residency training

Background

The COVID-19 pandemic has left an indelible effect on healthcare delivery and education system, including residency training. Particularly, neurosurgical departments worldwide had to adapt their operating model to the constantly changing pandemic landscape. This review aimed to quantify the reduction in neurosurgical operative volume and describe the impact of these trends on neurosurgical residency training.

Methods

We performed a comprehensive search of PubMed and EMBASE between December 2019 and October 2022 to identify studies comparing pre-pandemic and pandemic neurosurgical caseloads as well as articles detailing the impact of COVID-19 on neurosurgery residency training. Statistical analysis of quantitative data was presented as pooled odds ratio (OR) and 95% confidence intervals (CI).

Results

A total of 49 studies met the inclusion criteria, of which 12 (24.5%) were survey-based. The case volume of elective surgeries and non-elective procedures decreased by 70.4% (OR=0.296, 95%CI 0.210-0.418) and 68.2% (OR=0.318, 95%CI 0.193-0.525), respectively. A significant decrease was also observed in functional (OR=0.542, 95%CI 0.394-0.746), spine (OR=0.545, 95%CI 0.409-0.725), and skull base surgery (OR=0.545, 95%CI 0.409-0.725), whereas the caseloads for tumor (OR=1.029, 95%CI 0.838-1.263), trauma (OR=1.021, 95%CI 0.846-1.232), vascular (OR=1.001, 95%CI 0.870-1.152), and pediatric neurosurgery (OR=0.589, 95%CI 0.344-1.010) remained relatively the same between pre-pandemic and pandemic periods. The reduction in caseloads had caused concerns among residents and program directors in regard to the diminished clinical exposure, financial constraints, and mental well-being. Some positives highlighted were rapid adaptation to virtual educational platforms and increasing time for self-learning and research activities.

Conclusion

While COVID-19 has brought about significant disruptions in neurosurgical practice and training, this unprecedented challenge has opened the door for technological advances and collaboration that broaden the accessibility of resources and reduce the worldwide gap in neurosurgical education.

A scoping review to assess the effects of virtual reality in medical education and clinical care

Due to the challenges and restrictions posed by COVID-19 pandemic, technology and digital solutions played an important role in the rendering of necessary healthcare services, notably in medical education and clinical care. The aim of this scoping review was to analyze and sum up the most recent developments in Virtual Reality (VR) use for therapeutic care and medical education, with a focus on training medical students and patients. We identified 3743 studies, of which 28 were ultimately selected for the review. The search strategy followed the most recent Preferred Reporting Items for Systematic Reviews and Meta-Analysis for scoping review (PRISMA-ScR) guidelines. 11 studies (39.3%) in the field of medical education assessed different domains, such as knowledge, skills, attitudes, confidence, self-efficacy, and empathy. 17 studies (60.7%) focused on clinical care, particularly in the areas of mental health, and rehabilitation. Among these, 13 studies also investigated user experiences and feasibility in addition to clinical outcomes. Overall, the findings of our review reported considerable improvements in terms of medical education and clinical care. VR systems were also found to be safe, engaging, and beneficial by the studies' participants. There were huge variations in studies with respect to the study designs, VR contents, devices, evaluation methods, and treatment periods. In the future, studies may focus on creating definitive guidelines that can help in improving patient care further. Hence, there is an urgent need for researchers to collaborate with the VR industry and healthcare professionals to foster a better understanding of contents and simulation development.

From textbook to patient: a practical guide to train the end-to-side microvascular anastomosis

Microvascular anastomosis is one of the most challenging neurosurgical techniques. Mastering this technique allows to perform intracranial bypass with arteries of small caliber usually placed in deep narrow surgical fields. The aim of this paper is to describe step by step end-to-side microanastomosis training method by using polyvinyl alcohol (PVA) hydrogel tubing as it is easily reproducible. The tubing comes in sizes from 0.3 mm to 5 mm and has a texture and consistency similar to real vessels. This is based on the Teishinkai Hospital anastomosis technique. Continuous practice in microvascular anastomosis is of great importance in training vascular neurosurgeon. The PVA hydrogel tubing described in this article are useful and cost-effective material in the training of microvascular anastomosis. This practical guide model is easy to set up for repeated practice, and will contribute to facilitate 'off-the-job' training by young neurosurgeons and the development and maintenance of microsurgical skills in both resident neurosurgeons and experts who wish to master the various levels of anastomosis technique. There is no shortcut to master this technique, only hard work and perseverance.

Perception from students regarding online synchronous interactive teaching in the clinical year during COVID-19 pandemic

AIM

The global pandemic of COVID-19 has led to extensive practice of online learning. Our main objective is to compare different online synchronous interactive learning activities to evaluate students' perceptions. Moreover, we also aim to identify factors influencing their perceptions in these classes.

METHODS

A cross-sectional, questionnaire-based study focusing on clinical year medical students' perceptions and feedback was conducted between February 2021 -June 2021 at the University of Hong Kong. Online learning activities were divided into bedside teaching, practical skill session, problem-based learning (PBL) or tutorial, and lecture. A questionnaire based on the Dundee Ready Education Environment Measure (DREEM) was distributed to 716 clinical year students to document their perceptions.

RESULTS

One hundred responses were received with a response rate of 15.4% (110/716, including 96 from bedside teaching, 67 from practical skill session, 104 from PBL/tutorial, and 101 from lecture). For the mean score of the DREEM-extracted questionnaire, online PBL/tutorial scored the highest (2.72 ± 0.54), while bedside scored the lowest (2.38 ± 0.68, p = 0.001). Meanwhile, there was no significant difference when we compared different school years (p = 0.39), age (p = 0.37), gender (p = 1.00), year of internet experience (<17 vs ≥17 years p = 0.59), or prior online class experience (p = 0.62). When asked about students' preference for online vs face-to-face classes. Students showed higher preferences for online PBL/tutorial (2.06 ± 0.75) and lectures (2.27 ± 0.81). Distraction remains a significant problem across all four learning activities. A multivariate analysis was performed regarding students' reported behavior in comparison with their perception through the DREEM-extracted questionnaire. The results showed that good audio and video quality had a significant and positive correlation with their perception of online bedside teaching, practical skill sessions, and PBL/tutorial. It also showed that the use of the video camera correlated with an increase in perception scores for lectures.

CONCLUSION

The present analysis has demonstrated that students' perception of different online synchronous interactive learning activities varies. Further investigations are required on minimizing distraction during online classes.

Challenges and opportunities for educating health professionals after the COVID-19 pandemic

The education of health professionals substantially changed before, during, and after the COVID-19 pandemic. A 2010 Lancet Commission examined the 100-year history of health-professional education, beginning with the 1910 Flexner report. Since the publication of the Lancet Commission, several transformative developments have happened, including in competency-based education, interprofessional education, and the large-scale application of information technology to education. Although the COVID-19 pandemic did not initiate these developments, it increased their implementation, and they are likely to have a long-term effect on health-professional education. They converge with other societal changes, such as globalisation of health care and increasing concerns of health disparities across the world, that were exacerbated by the pandemic. In this Health Policy, we list institutional and instructional reforms to assess what has happened to health-professional education since the publication of the Lancet Commission and how the COVID-19 pandemic altered the education process.

Pivot to online learning for adapting or continuing workplace-based clinical learning in medical education following the COVID-19 pandemic: A BEME systematic review: BEME Guide No. 70

BACKGROUND

The novel coronavirus disease was declared a pandemic in March 2020, which necessitated adaptations to medical education. This systematic review synthesises published reports of medical educational developments and innovations that pivot to online learning from workplace-based clinical learning in response to the pandemic. The objectives were to synthesise what adaptations/innovation were implemented (description), their impact (justification), and 'how' and 'why' these were selected (explanation and rationale).

METHODS

The authors systematically searched four online databases up to December 21, 2020. Two authors independently screened titles, abstracts and full-texts, performed data extraction, and assessed the risk of bias. Our findings are reported in alignment with the STORIES (STructured apprOach to the Reporting in healthcare education of Evidence Synthesis) statement and BEME guidance.

RESULTS

Fifty-five articles were included. Most were from North America (n = 40), and nearly 70% focused on undergraduate medical education (UGME). Key developments were rapid shifts from workplace-based learning to virtual spaces, including online electives, telesimulation, telehealth, radiology, and pathology image repositories, live-streaming or pre-recorded videos of surgical procedures, stepping up of medical students to support clinical services, remote adaptations for clinical visits, multidisciplinary team meetings and ward rounds. Challenges included lack of personal interactions, lack of standardised telemedicine curricula and need for faculty time, technical resources, and devices. Assessment of risk of bias revealed poor reporting of underpinning theory, resources, setting, educational methods, and content.

CONCLUSIONS

This review highlights the response of medical educators in deploying adaptations and innovations. Whilst few are new, the complexity, concomitant use of multiple methods and the specific pragmatic choices of educators offers useful insight to clinical teachers who wish to deploy such methods within their own practice. Future works that offer more specific details to allow replication and understanding of conceptual underpinnings are likely to justify an update to this review.

Solutions, enablers and barriers to online learning in clinical medical education during the first year of the COVID-19 pandemic: A rapid review

AIMS

The COVID-19 pandemic has seen a major disruption to undergraduate and postgraduate clinical medical education. The aim of this rapid review was to identify and synthesize published literature relating to the solutions, enablers and barriers to online learning implemented in clinical medical education during the first year of the COVID-19 pandemic.

METHODS

All articles published before March 2021 in peer-reviewed journals, including MedEdPublish, that described authors' experience of online learning in response to the COVID-19 pandemic. A descriptive analysis of the solutions and a qualitative template analysis of enablers and barriers.

RESULTS

87 articles were identified for inclusion. Face to face teaching was maintained with interactive approaches between learners and/or learners and teachers. Several innovative solutions were identified. The enablers were a readiness and rapid response by institutions, with innovation by teachers. The barriers were the lack of planning and resources, usability problems and limited interactivity between teachers and students.

CONCLUSIONS

Important and timely evidence was obtained that can inform future policy, practice and research. The findings highlighted the urgent need to use rapid design and implementation methods with greater explicit descriptions in published articles to ensure applicability to other contexts.

Creating a Proficiency-based Remote Laparoscopic Skills Curriculum for the COVID-19 Era

OBJECTIVE

Social distancing restrictions due to COVID-19 challenged our ability to educate incoming surgery interns who depend on early simulation training for basic skill acquisition. This study aimed to create a proficiency-based laparoscopic skills curriculum using remote learning.

DESIGN

Content experts designed 5 surgical tasks to address hand-eye coordination, depth perception, and precision cutting. A scoring formula was used to measure performance: cutoff time - completion time - (K × errors) = score; the constant K was determined for each task. As a benchmark for proficiency, a fellowship-trained laparoscopic surgeon performed 3 consecutive repetitions of each task; proficiency was defined as the surgeon's mean score minus 2 standard deviations. To train remotely, PGY1 surgery residents (n = 29) were each issued a donated portable laparoscopic training box, task explanations, and score sheets. Remote training included submitting a pre-test video, self-training to proficiency, and submitting a post-test video. Construct validity (expert vs. trainee pre-tests) and skill acquisition (trainee pre-tests vs. post-tests) were compared using a Wilcoxon test (median [IQR] reported).

SETTING

The University of Texas Southwestern Medical Center in Dallas, Texas PARTICIPANTS: Surgery interns RESULTS: Expert and trainee pre-test performance was significantly different for all tasks, supporting construct validity. One trainee was proficient at pre-test. After 1 month of self-training, 7 additional residents achieved proficiency on all 5 tasks after 2-18 repetitions; trainee post-test scores were significantly improved versus pre-test on all tasks (p = 0.01).

CONCLUSIONS

This proficiency-based curriculum demonstrated construct validity, was feasible as a remote teaching option, and resulted in significant skill acquisition. The remote format, including video-based performance assessment, facilitates effective at-home learning and may allow additional innovations such as video-based coaching for more advanced curricula.

The impact of the COVID-19 pandemic on global neurosurgical education: a systematic review

The COVID-19 pandemic has disrupted neurosurgical training worldwide, with the shutdown of academic institutions and the reduction of elective surgical procedures. This impact has disproportionately affected LMICs (lower- and/or middle-income countries), already burdened by a lack of neurosurgical resources. Thus, a systematic review was conducted to examine these challenges and innovations developed to adapt effective teaching and learning for medical students and neurosurgical trainees. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and The Cochrane Handbook of Systematic Reviews of Interventions. MEDLINE, PubMed, Embase and Cochrane databases were accessed, searching and screening literature from December 2019 to 5th December 2020 with set inclusion and exclusion criteria. Screening identified 1254 articles of which 26 were included, providing data from 96 countries. Twenty-three studies reported transition to online learning, with 8 studies also mentioned redeployment into COVID wards with 2 studies mentioning missed surgical exposure as a consequence. Of 7 studies conducted in LMICs, 3 reported residents suffering financial insecurities from reduced surgical caseload and recession. Significant global disruption in neurosurgical teaching and training has arisen from the COVID-19 pandemic. Decreased surgical exposure has negatively impacted educational provision. However, advancements in virtual technology have allowed for more affordable, accessible training especially in LMICs. Using this, initiatives to reduce physical and mental stress experienced by trainees should be paramount.

No Microscope? No Problem: A Systematic Review of Microscope-Free Microsurgery Training Models

BACKGROUND

 Benchtop microsurgical training models that use digital tools (smartphones, tablets, and virtual reality [VR]) for magnification are allowing trainees to practice without operating microscopes. This systematic review identifies existing microscope-free training models, compares models in their ability to enhance microsurgical skills, and presents a step-by-step protocol for surgeons seeking to assemble their own microsurgery training model.

METHODS

 We queried PubMed, Embase, and Web of Science databases through November 2020 for microsurgery training models and performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We collected data including training model characteristics (cost, magnification, and components) and outcomes (trainee satisfaction, image resolution, and faster suturing speed). We also conducted a complimentary Google search to identify commercially available microscope-free microsurgical training models or kits not reported in peer-reviewed literature.

RESULTS

 Literature search identified 1,805 publications; 24 of these met inclusion criteria. Magnification tools most commonly included smartphones (n = 10), VR simulators (n = 4), and tablets (n = 3), with magnification ranging up to ×250 magnification on digital microscopy, ×50 on smartphones, and ×5 on tablets. Average cost of training models ranged from $13 (magnification lens) to $15,000 (augmented reality model). Model were formally assessed using workshops with trainees or attendings (n = 10), surveys to end-users (n = 5), and single-user training (n = 4); users-reported satisfaction with training models and demonstrated faster suturing speed and increased suturing quality with model training. Five commercially available microsurgery training models were identified through Google search.

CONCLUSION

 Benchtop microsurgery trainers using digital magnification successfully provide trainees with increased ease of microsurgery training. Low-cost yet high magnification setups using digital microscopes and smartphones are optimal for trainees to improve microsurgical skills. Our assembly protocol, "1, 2, 3, Microsurgery," provides instructions for training model set up to fit the unique needs of any microsurgery trainee.
