OBJECTIVE: The longer learning curve and smaller margin of error make nontraditional, or "out of operating room" simulation training, essential in neurosurgery. In this study, the authors propose an evaluation system for residents combining both task-based and procedure-based exercises and also present the perception of residents regarding its utility. METHODS: Residents were evaluated using a combination of task-based and virtual reality (VR)-based exercises. The results were analyzed in terms of the seniority of the residents as well as their laboratory credits. Questionnaire-based feedback was sought from the residents regarding the utility of this evaluation system incorporating the VR-based exercises. RESULTS: A total of 35 residents were included in this study and were divided into 3 groups according to seniority. There were 11 residents in groups 1 and 3 and 13 residents in group 2. On the overall assessment of microsuturing skills including both 4-0 and 10-0 microsuturing, the suturing skills of groups 2 and 3 were observed to be better than those of group 1 (p = 0.0014). Additionally, it was found that microsuturing scores improved significantly with the increasing laboratory credits (R2 = 0.72, p < 0.001), and this was found to be the most significant for group 1 residents (R2 = 0.85, p < 0.001). Group 3 residents performed significantly better than the other two groups in both straight (p = 0.02) and diagonal (p = 0.042) ring transfer tasks, but there was no significant difference between group 1 and group 2 residents (p = 0.35). Endoscopic evaluation points were also found to be positively correlated with previous laboratory training (p = 0.002); however, for the individual seniority groups, the correlation failed to reach statistical significance. The 3 seniority groups performed similarly in the cranial and spinal VR modules. Group 3 residents showed significant disagreement with the utility of the VR platform for improving surgical dexterity (p = 0.027) and improving the understanding of surgical procedures (p = 0.034). Similarly, there was greater disagreement for VR-based evaluation to identify target areas of improvement among the senior residents (groups 2 and 3), but it did not reach statistical significance (p = 0.194). CONCLUSIONS: The combination of task- and procedure-based assessment of trainees using physical and VR simulation models can supplement the existing neurosurgery curriculum. The currently available VR-based simulations are useful in the early years of training, but they need significant improvement to offer beneficial learning opportunities to senior trainees.

BACKGROUND: The Covid-19 pandemic has created the largest disruption of education in history. In a response to this, we aimed to evaluate the knee arthroscopy learning curve among medical students and orthopaedic residents. METHODS: An arthroscopy simulator was used to compare the learning curves of two groups. Medical students with any prior knowledge of arthroscopy (n=24) were compared to a residents group (n=16). Analyzed parameters were "time to complete a task," assessment of the movement of tools and values scoring damage to the surrounding tissues. RESULTS: After several repetitions, both groups improved their skills in terms of time and movement. Residents were on average faster, had less camera movement, and touched the cartilage tissue less often than did students. Students showed a steeper improvement curve than residents for certain parameters, as they started from a different experience level. CONCLUSION: The participants were able to reduce the time to complete a task. There was also a decrease in possible damage to the virtual surrounding tissues. In general, the residents had better mean values, but the students had the steeper learning curve. Particularly less experienced surgeons can especially train their hand-eye coordination skills required for arthroscopy surgery. Training simulators are an important training tool that supplements cadaveric training and participation in arthroscopic operations and should be included in training.

BACKGROUND: The disposable bronchoscope is an excellent alternative to face the problem of SARS-CoV-2 and other cross infections, but the bronchoscopist's perception of its quality has not been evaluated. METHODS: To evaluate the quality of the Ambu-aScope4 disposable bronchoscope, we carried out a cross-sectional study in 21 Spanish pulmonology services. We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy. The variables were described with absolute and relative frequencies, measures of central tendency and dispersion depending on their nature. The existence of learning curves was evaluated by CUSUM analysis. RESULTS: The most frequent indications in 300 included bronchoscopies was bronchial aspiration in 69.3% and the median duration of these was 9.1 min. The route of entry was nasal in 47.2% and oral in 34.1%. The average score for ease of use, image, and aspiration quality was 80/100. All the planned techniques were performed in 94.9% and the bronchoscopist was satisfied in 96.6% of the bronchoscopies. They highlighted the portability and immediacy of the aScope4TM to start the procedure in 99.3%, the possibility of taking and storing images in 99.3%. The CUSUM analysis showed average scores > 70/100 from the first procedure and from the 9th procedure more than 80% of the scores exceeded the 80/100 score. CONCLUSIONS: The aScope4™ scored well for ease of use, imaging, and aspiration. We found a learning curve with excellent scores from the 9th procedure. Bronchoscopists highlighted its portability, immediacy of use and the possibility of taking and storing images.

The COVID-19 pandemic has pushed medical providers to trial telemedicine on a scale that lacks precedent. In genetic medicine, nearly overnight genetics providers were asked to transition to telemedicine platforms, irrespective of their previous experience with these modalities. This push to telegenetics prompted a reappraisal of the practice, as genetics providers learned firsthand about the feasibility, benefits, and drawbacks of telegenetics and telesupervision, all of which raise questions about the potential incorporation of these platforms beyond the pandemic. Adding to nascent literature on the transition to telegenetics amidst the COVID-19 pandemic, we aimed to evaluate provider experiences and preferences with respect to telegenetics through qualitative semi-structured interviews with genetics providers. Nineteen providers from seven institutions participated in a semi-structured interview focused on the rapid shift to telegenetics, the benefits and drawbacks of the practice, experiences supervising students on virtual platforms, and providers' preferences. We employed a qualitative methodology so that providers working across diverse subspecialties could expand upon previously reported benefits and drawbacks. Qualitative data revealed the nuanced benefits of telegenetics which included overcoming geographic, spatial, and temporal barriers to care as well as greater involvement of patients' family members in sessions. In addition, the data indicated drawbacks related to additional tasks such as completing paperwork electronically and facilitating the collection of specimens from patients' homes. Interviews with providers from different subspecialties revealed how telegenetics may be uniquely useful for particular subspecialties, patient populations, or clinics for whom the aforementioned barriers are more significant. Providers reported that telesupervision made the provision of feedback to students more cumbersome and identified a number of methods for enriching the telesupervision experience. In keeping with previous research, most genetics providers appraised telegenetics as a valuable addition to patient care (68%, N = 13) and hoped to offer it as an option beyond the pandemic (63%, N = 12).

In patients with SARS-CoV-2 infection, endotracheal intubation is a procedure with a high risk for transmission. A videolaryngoscopy is a supplementary level of health care provider protection, but commercial videolaryngoscopes are expensive and not always available in pediatric intensive care units in Argentina. Our objective was to describe intubation practice using an infant head mannequin with a low-cost, handcrafted videolaryngoscope. Fifteen pediatricians with no prior experience using the device participated in an intubation practice in a head mannequin with a handcrafted videolaryngoscope. The average time for the first attempt was 116.4 seconds (95 % confidence interval [CI]: 84.8- 148.0) and, for the second one, 44.2 seconds (95 % CI: 27.7-60.6). Time decreased significantly for the second attempt (p: 0.0001). A successful intubation was achieved with the device in all attempts, and the procedure duration decreased with the second practice.

En pacientes con infección por SARS-CoV-2 la intubación endotraqueal es un procedimiento con riesgo elevado de contagio. La videolaringoscopia complementa la protección del profesional, pero los videolaringoscopios comerciales son caros y no siempre están disponibles en las terapias intensivas pediátricas argentinas. El objetivo fue describir la práctica de intubación en un modelo de cabeza de simulación de lactante con un videolaringoscopio artesanal de bajo costo. Quince pediatras sin experiencia previa con el dispositivo participaron de una práctica de intubación en una cabeza de simulación con un videolaringoscopio artesanal. El tiempo promedio del primer intento fue de 116,4 segundos (intervalo de confianza del 95 % [IC95 %]: 84,8-148,0) y, el del siguiente fue de 44,2 segundos (IC95 %: 27,7­60,6). El tiempo disminuyó de forma significativa en el segundo intento (p : 0,0001). El dispositivo permitió la intubación exitosa en todos los intentos acortando la duración del procedimiento en la segunda práctica.

This study was designed to determine the effect of a novel simulation-based training curriculum for scleral tunnel construction in manual small incision cataract surgery (MSICS) compared with traditional training. In this multicenter, investigator-masked, randomized clinical trial, resident surgeons within 3 months of matriculation with minimal or no prior experience with MSICS were assigned either to simulation-based training, the Experimental Group (EG), or to conventional training, the Control Group (CG). EG residents were trained to perform scleral tunnel construction using a simulation-based curriculum (HelpMeSee Eye Surgery Simulator), while residents in the CG followed institution-specific curriculum before progressing to live surgery. Surgical videos of the first 20 attempts at tunnel construction were reviewed by masked video raters. The primary outcome was the total number of any of 9 pre-specified errors. On average, the total number of errors was 9.25 (95% CI 0-18.95) in the EG and 17.56 (95% CI 6.63-28.49) in the CG (P = 0.05); the number of major errors was 4.86 (95% CI 0.13-9.59) in the EG and 10.09 (95% CI 4.76-15.41) in the CG (P = 0.02); and the number of minor errors was 4.39 (95% CI 0-9.75) in the EG and 7.47 (95% CI 1.43-13.51) in the CG (P = 0.16). These results support that novice surgeons trained using the novel simulation-based curriculum performed fewer errors in their first 20 attempts at tunnel construction compared to those trained with a conventional curriculum.

Tasked with identifying digital health solutions to support dynamic learning health systems and their response to COVID-19, the US Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response partnered with the University of New Mexico's Project ECHO and more than 2 dozen other organizations and agencies to create a real-time virtual peer-to-peer clinical education opportunity: the COVID-19 Clinical Rounds Initiative. Focused on 3 "pressure points" in the COVID-19 continuum of care-(1) the out-of-hospital and/or emergency medical services setting, (2) emergency departments, and (3) inpatient critical care environments-the initiative has created a massive peer-to-peer learning network for real-time information sharing, engaging participants in all 50 US states and more than 100 countries. One hundred twenty-five learning sessions had been conducted between March 24, 2020 and February 25, 2021, delivering more than 58,000 total learner-hours of contact in the first 11 months of operation.

PURPOSE: The COVID-19 pandemic has produced an unequaled human crisis forcing a radical reorganization in the healthcare system. Otolaryngologists are at high risk of exposure, and changes in medical and surgical activities have reduced the learning opportunity for residents and fellows. We believe that even during COVID-19 crisis it is mandatory to guarantee an optimal training, and here, we propose some strategies, based on our experience, to further increase our trainees' learning curve. METHODS: We asked our trainees to fill out an electronic survey about several aspect of their training: a first section focused on the reduction of clinical activities and the perceived impact of the pandemic on residents' skills; the second part outlined the type of attended training activity and the perceived benefit. RESULTS: Surgical training has been reported by our residents as the activity perceived to be the most contracted during the pandemic. According to residents' opinion the most useful activities were dissection (n = 8, 53.4% residents) and online journal clubs/webinars (n = 7, 46.6% of residents). Residents' suggestions included actively participating to tracheostomy procedures on SARS-CoV-2 positive patients, attending lessons held by senior consultants on basic ENT topics and promoting collegial discussion of inpatient clinical cases. CONCLUSION: Building on this dramatic experience, we must be ready for a global restructuring of the residency program to provide an adequate trainee education for the future surgeons.
