Simulation-Based Telemedicine Training Program for Residents in Physical Medicine and Rehabilitation: A Virtual Standardized Patient Activity

Background: The COVID-19 pandemic has ushered in a new era of healthcare delivery, emphasizing the crucial role of telemedicine. This study aimed to address the training needs of physical medicine and rehabilitation (PM&R) residents in telemedicine through an Interactive Virtual Telemedicine training program utilizing standardized patient methodology. Methods: A tailored virtual standardized patient simulation module was developed for PM&R residents. Prior to the training, residents completed pre-training questionnaires. The training consisted of (1) a 2-hour classroom didactic session covering telemedicine strategies for conducting physical examinations and triaging, as well as anticipated challenges. (2) a 2-hour zoom telemedicine simulation training exposed residents to three distinct patient scenarios (sickle cell crisis, acute low back pain, and neurorehabilitation). (3) a three-stage debriefing tool was employed for post-training reflection. Results: Eight PM&R residents, predominantly males, with varying prior exposure to telemedicine, participated in the study. Post-training evaluations indicated that residents overwhelmingly found the simulation-based telemedicine training valuable and worth the didactic time invested. Data analysis demonstrated a significant increase in residents’ knowledge and confidence in telemedicine skills. Discussion: The study’s findings suggest that the telemedicine training program effectively enhanced residents’ understanding and confidence in telemedicine skills. Future research endeavors could involve a larger and more diverse group of residents to further assess training effectiveness and gather a wider array of perspectives on telemedicine. Expanding the use of standardized patients in telemedicine simulation training holds promise for advancing medical education in this evolving healthcare landscape.

Teaching of manual cataract extraction in ophthalmic surgical training programmes.

Manual cataract extraction techniques such as extracapsular cataract extraction (ECCE) or manual small incision cataract (MSICS) surgery have been replaced by phacoemulsification cataract surgery. Surgical training opportunities for manual techniques of cataract extraction are limited in modern surgical training programmes. This study evaluated the current trends of ECCE/MSICS training opportunities amongst trainees and trainers in the Irish Ophthalmic Surgical Training Program. An electronic survey was distributed to all ophthalmic surgical trainees and consultants in the country. It addressed the experience and exposure to ECCE/MSICS. Nineteen of 33 (57%) trainees and 29 of 55 (55%) of consultants completed the survey. Twelve of 19 (63%) trainees viewed an ECCE procedure performed live. Twenty-seven of 29 (93%) consultants performed an ECCE procedure during their surgical career; 8 of 27 (30%) performed an ECCE within the last 1-3 years. Fourteen of 19 (74%) trainees stated they do not feel confident converting from phacoemulsification to ECCE independently. Sixteen of 19 (89%) trainees believe manual cataract extraction training should be included in their surgical training. Nineteen of 29 (65%) consultants believe training in manual cataract extraction should be part of the surgical training programme. There is a paucity of manual cataract extraction being performed in Ireland, limiting live surgical training in this technique. This survey highlights the limited experience of trainees in this valuable skill that is occasionally required for a successful surgical outcome. The authors conclude that wet laboratory simulated training of manual cataract extraction will bridge this gap.

Validation of a synthetic simulation model of endoscopic rectus sheath plication.

Literature reviews outline minimally invasive approaches for abdominal diastasis in patients without skin excess. However, few surgeons are trained in endoscopic rectus sheath plication, and no simulated training programs exist for this method. This study aimed to develop and validate a synthetic simulation model for the training of skills in this approach under the Messick validity framework. A cross-sectional study was carried out to assess the participants' previous level of laparoscopic/endoscopic skills by a questionnaire. Participants performed an endoscopic plication on the model and their performance was evaluated by one blinded observer using the global rating scale OSATS and a procedure specific checklist (PSC) scale. A 5-level Likert survey was applied to 5 experts and 4 plastic surgeons to assess Face and Content validity. Fifteen non-experts and 5 experts in abdominal wall endoscopic surgery were recruited. A median OSATS score [25 (range 24-25) vs 14 (range 5-22); p < 0.05 of maximum 25 points] and a median PSC score [11 (range 10-11) vs 8 (range 3-10); p < 0.05 of maximum 11 points] was significantly higher for experts compared with nonexperts. All experts agreed or strongly agreed that the model simulates a real scenario of endoscopic plication of the rectus sheath. Our simulation model met all validation criteria outlined in the Messick framework, demonstrating its ability to differentiate between experts and non-experts based on their baseline endoscopic surgical skills. This model stands as a valuable tool for evaluating skills in endoscopic rectus sheath plication.

Role of surgical simulation on self-reported confidence level on cardiothoracic surgical trainees.

Simulated self-practice using simulation models could improve fine motor skills and self confidence in surgical trainees. The purpose of this study is to evaluate on self-reported confidence level in cardiothoracic surgical trainees by using surgical simulation models. We conducted a cross-sectional study on all surgeons (n=10) involved in MIS simulation training. All surgeons are required to perform on three minimally invasive surgery (MIS) procedures (Mitral Valve Repair, Mitral Valve Replacement and Aortic Valve Replacement). A questionnaire was designed based on two existing scales related to self-confidence, the surgical self-efficacy scale [SSES] and the perceived competency scale [PCS]. We assessed their self-confidence (before and after training) in the use of simulation in MIS procedures using rating scales 1-5. The mean score was calculated for each domain and used as the predictor variable. We also developed six questions (PCS) using Objective Structured Assessment of Technical Skills (OSAT) related to each domain and asked participants how confident they were after performing each MICS procedure. The mean score was 4.7 for all assessed domains, except "knowledge" (3.8). Surgeons who had performed one or more MIS procedures had higher scores (P<0.05). There was no correlation between the number of MIS procedures performed and self-confidence scores. The results indicate that the cardiac surgery training based on MIS simulation improves trainees and consultants in terms of the level of self-confidence. Although surgeons generally have high levels of self-confidence after simulation training in MIS cardiac procedures, there is still room for improvement with respect to technical skills related to the procedure itself and its results.

A Statewide Mobile Simulation Program For Improving Obstetric Skills in Rural Hospitals.

Closure of rural obstetric (OB) units has led to maternal care deserts, causing mothers to travel long distances for maternity care. Emergency departments (EDs) in hospitals where OB units have closed require regular training for personnel to maintain OB skills, as do rural Level-1 OB units with low volumes of maternity cases. We used a federal grant to develop an OB mobile simulation program to bring simulation-based training to rural providers. Our goal was to improve OB skills and standardize care through the framework of the Alliance for Innovation in Maternal Health (AIM) Patient Safety Bundles. We conducted needs assessments and built a mobile simulation unit. We defined 2 groups of learners: those in Level-1 OB units and those in EDs without OB units. For Level-1 OB units, we created a train-the-trainer curriculum, to create a statewide cohort of simulation experts to implement simulations in their facilities between our visits. We gifted each Level-1 unit an OB task trainer, implemented virtual train-the-trainer simulation and task trainer workshops, and conducted post-workshop assessments. We then traveled to each Level-1 unit and helped the cohort implement in situ simulations for their staff using facility-specific resources. We conducted assessments for the cohort and the hospital staff after the simulations. For EDs, we delivered virtual didactics to improve basic OB knowledge, then traveled to ED units, implemented in situ simulations, and conducted post-simulation assessments. We chose a postpartum hemorrhage (PPH) scenario for our first round of simulations. After train-the-trainer simulation workshops, 98% of participants surveyed agreed that workshop goals and objectives were achieved. After the task trainer workshop, 95% surveyed agreed that their knowledge of using the simulator had improved. After implementing in situ simulations in Level-1 OB units, 98.8% of the train-the-trainer cohort found that their ability to implement simulations had improved. The hospital staff participating in the simulations identified a 30% increase in ability to manage PPH. For the ED staff, postdidactic evaluations identified that 95.4% of participants reported moderate improvement in basic OB knowledge and after participation in the simulations >95% reported better skills as an ED team member when caring for pregnant patients. These results demonstrate improved skills of hospital staff in simulated PPH in Level-1 OB units and simulated OB emergencies in EDs that no longer have OB units. Further studies are warranted to assess improvement in maternal outcomes.

Preceptorship in robotic colorectal surgery: experience from the Australian private sector

This article describes a post-fellowship preceptorship training program to train sub-specialty colorectal surgeons in gaining proficiency in robotic colorectal surgery using a dual-surgeon model in the Australian private sector. The Australian colorectal surgeon faces challenges in gaining robotic colorectal surgery proficiency with limited exposure and experience in the public setting where the majority of general and colorectal surgery training is currently conducted. This training model uses graded exposure with a range of simulation training, wet lab training, and clinical operative cases to progress through both competency and proficiency in robotic colorectal surgery which is mutually beneficial to surgeons and patients alike. Ongoing audit of practice has shown no adverse impacts.

Correlation of Self-Assessed Manual Dexterity and Actual Performance in Surgical Simulation – One Year Follow Up

Abstract Background Simulation training has proved to be beneficial in many fields of professions including medicine and might be included already during medical school. Aims We evaluated if medical students rate their manual dexterity as good or above average and if this self-assessment (SA) correlates with the actual performance in a surgical simulation. Methods Basic surgical tasks have been performed by medical students in the 3rd and 4th year for a total of 4 rounds on 2 identical Lap-Sim® surgical simulators. Three questionnaires, before and after the simulation as well as follow up after 1 year had to be answered. Descriptive statistics stratified by career goal (surgical/ undecided/ nonsurgical) for outcomes of simulation parameters are reported. Associations between surgical career goal and SA of manual dexterity with three performance parameters (tissue damage, time and path length) are estimated in linear regression models. Results Out of 102 participating students 41 stated surgery as their career goal, 18 a nonsurgical field, and 43 were undecided. 87.8% of the surgical group rated their dexterity as good or above average (86.1% in the undecided group), 88.9% of the nonsurgical group as below average or good. A positive association of SA with tissue damage has been found statistically significant (p=0.033). One year after the simulation (n=97) 13.4% changed their career goal from undecided to surgical, whereas 8.2% changed from undecided to non-surgical. 92.7% wanted to have simulation training integrated into the curriculum. Conclusion A correlation of self-assessed manual dexterity has been found in the surgical group for tissue damage, but not for time and path length. Simulation training might help students in decision making for a surgical field and therefore recruit future surgeons, which could be shown in the one-year follow-up.

Comparative Analysis of Circulating Metabolomic Profiles Identifies Shared Metabolic Alterations Across Distinct Multi-Stressor Military Training Operations.

Military training provides insight into metabolic responses under unique physiological demands that can be comprehensively characterized by global metabolomic profiling to identify potential strategies for improving performance. This study identified shared changes in metabolomic profiles across three distinct military training exercises varying in magnitude and types of stress. Blood samples collected before and after three real or simulated military training exercises were analyzed using the same untargeted metabolomic profiling platform. Exercises included a three-week survival school course (ST, n=36), a four-day arctic cross country ski march (AT, n=24), and a 28-day controlled diet- and exercise-induced energy deficit (CED, n=26). Log2-fold changes of >±1 in 191, 121 and 64 metabolites were identified in the ST, AT and CED datasets, respectively. Most metabolite changes were within lipid (57-63%) and amino acid metabolism (18-19%) pathways, and changes in 87 were shared across studies. The largest and most consistent increases in shared metabolites were found in acylcarnitine, fatty acid, ketone, and glutathione metabolism pathways, whereas the largest decreases were in diacylglycerol and urea cycle metabolism pathways. Multiple shared metabolites were consistently correlated with biomarkers of inflammation, tissue damage, and anabolic hormones across studies. These three studies of real and simulated military training revealed overlapping alterations in metabolomic profiles despite differences in environment and the stressors involved. Consistent changes in metabolites related to lipid metabolism, ketogenesis and oxidative stress suggest a potential common metabolomic signature associated with inflammation, tissue damage and suppression of anabolic signaling that may characterize unique physiological demands of military training.

Simulation training on respectful emergency obstetric and neonatal care in north-western Madagascar: a mixed-methods evaluation of an innovative training program

BackgroundThe rates of maternal and neonatal deaths in Madagascar are among the highest in the world. In response to a request for additional training from obstetrical care providers at the Ambanja district hospital in north-eastern Madagascar, a partnership of institutions in Switzerland and Madagascar conducted innovative training on respectful emergency obstetric and newborn care using e-learning and simulation methodologies. The training focused on six topics: pre-eclampsia, physiological childbirth, obstetric maneuvers, postpartum hemorrhage, maternal sepsis, and newborn resuscitation. Cross-cutting themes were interprofessional communication and respectful patient care. Ten experienced trainers participated in an e-training-of-trainers course conducted by the Swiss partners. The newly-trained trainers and Swiss partners then jointly conducted the hybrid remote/in-person training for 11 obstetrical care providers in Ambanja.MethodsA mixed methods evaluation was conducted of the impact of the training on participants’ knowledge and practices. Trainees’ knowledge was tested before, immediately after, and 6 months after the training. Focus group discussions were conducted to elicit participants’ opinions about the training, including the content and pedagogical methods.ResultsTrainees’ knowledge of the six topics was higher at 6 months (with an average of 71% correct answers) compared to before the training (62%), although it was even higher (83%) immediately after the training. During the focus group discussions, participants highlighted their positive impressions of the training, including its impact on their sense of professional effectiveness. They reported that their interprofessional relationships and focus on respectful care had improved. Simulation, which was a new methodology for the participants native to Madagascar, was appreciated for its engaging and active format, and they enjoyed the hybrid delivery of the training. Participants (including the trainers) expressed a desire for follow-up engagement, including additional training, and improved access to more equipment.ConclusionThe evaluation showed improvements in trainees’ knowledge and capacity to provide respectful emergency care to pregnant women and newborns across all training topics. The hybrid simulation-based training method elicited strong enthusiasm. Significant opportunity exists to expand the use of hybrid onsite/remote simulation-based training to improve obstetrical care and health outcomes for women and newborns in Madagascar and elsewhere.

Application of Computerized Surgical Planning in Craniosynostosis Surgery

AbstractCraniosynostosis, a medical condition characterized by premature fusion of one or multiple cranial sutures, has historically been treated through surgical correction. Computerized Surgical Planning (CSP) and three-dimensional (3D) modeling have gained significant popularity across craniofacial surgery. Through a collaborative effort between surgeons and engineers, it is now possible to virtually execute a surgical plan based on preoperative imaging using computed tomography scans. The CSP workflow involves several elements including virtual 3D modeling, CSP computer-aided surgical guide design, manufacturing of guides and templates, and intraoperative implementation. Through the gradual optimization of this workflow, it has been possible to achieve significant progress in the surgical process including improvements in the preoperative planning of complex craniosynostosis cases and reduction of intraoperative time. Furthermore, CSP and 3D modeling have had a positive impact on surgical simulation and residency training, along with patient education and counseling. This article summarizes the CSP workflow in the treatment of craniosynostosis and the implications of this treatment modality on medical trainee education and patient management.

Imaging through thick scattering media based on envelope-informed learning with a simulated training dataset

Computational imaging faces significant challenges in dealing with multiple scattering through thick complex media. While deep learning has addressed some ill-posed problems in scattering imaging, its practical application is limited by the acquisition of the training dataset. In this study, the Gaussian-distributed envelope of the speckle image is employed to simulate the point spread function (PSF), and the training dataset is obtained by the convolution of the handwritten digits with the PSF. This approach reduces the requirement of time and conditions for constructing the training dataset and enables a neural network trained on this dataset to reconstruct objects obscured by an unknown scattering medium in real experiments. The quality of reconstructed objects is negatively correlated with the thickness of the scattering medium. Our proposed method provides a new way, to the best of our knowledge, to apply deep learning in scattering imaging by reducing the time needed for constructing the training dataset.

Quantifying the Environmental Impact of Private and Commercial Pilot License Training in Canada

As the global aviation sector expands to accommodate increasing air travel demand, the subsequent rise in flights exacerbates carbon dioxide (CO2) emissions, challenging the sector’s environmental sustainability. Targeting net-zero emissions by 2050, international aviation agencies are stressing the imperative of reducing emissions directly at their source. While the literature provides abundant estimates of aviation emissions from airline flights, there has been a lack of work aimed at quantifying CO2 emissions specific to the general aviation sector. This study investigates CO2 emissions attributed to the pilot training sub-sector within Canada’s general aviation sector. It specifically examines the initial phase of pilot training, known as ab initio training, extending through to the attainment of a commercial pilot license. Utilizing a mathematical framework alongside assumptions, combined with data on license issuances over a 23-year period, it estimated that each hour of flight training emits about 70.4 kg of CO2, varying between 44.9 kg and 94.9 kg per hour. Annual CO2 emissions from Canada’s ab initio pilot training are estimated at approximately 30,000 tons, with a possible range of 19,000 to 40,000 tons. The study also explores mitigation opportunities, such as flight simulation training devices and electric aircraft. Though focusing on Canada’s ab initio pilot training, the findings have international relevance.

Establishment and validation of an artificial intelligence-based model for real-time detection and classification of colorectal adenoma

Colorectal cancer (CRC) prevention requires early detection and removal of adenomas. We aimed to develop a computational model for real-time detection and classification of colorectal adenoma. Computationally constrained background based on real-time detection, we propose an improved adaptive lightweight ensemble model for real-time detection and classification of adenomas and other polyps. Firstly, we devised an adaptive lightweight network modification and effective training strategy to diminish the computational requirements for real-time detection. Secondly, by integrating the adaptive lightweight YOLOv4 with the single shot multibox detector network, we established the adaptive small object detection ensemble (ASODE) model, which enhances the precision of detecting target polyps without significantly increasing the model's memory footprint. We conducted simulated training using clinical colonoscopy images and videos to validate the method's performance, extracting features from 1148 polyps and employing a confidence threshold of 0.5 to filter out low-confidence sample predictions. Finally, compared to state-of-the-art models, our ASODE model demonstrated superior performance. In the test set, the sensitivity of images and videos reached 87.96% and 92.31%, respectively. Additionally, the ASODE model achieved an accuracy of 92.70% for adenoma detection with a false positive rate of 8.18%. Training results indicate the effectiveness of our method in classifying small polyps. Our model exhibits remarkable performance in real-time detection of colorectal adenomas, serving as a reliable tool for assisting endoscopists.

Development of practical emergency simulation training in primary health care: Lessons learnt

Emergency care in the primary health care setting is often sub-optimal leading to physician stress and adverse patient outcomes. Formal training opportunities in the management of emergency management are limited in public-sector facilities. Two family physicians conducted emergency simulation drills at primary health care facilities to address this need. The multi-disciplinary team at these facilities were involved, and each drill was followed by reflection and feedback. The drill evolved over an 18 month period, and the simulations as well as the feedback process were reviewed and improved. Reported benefits included improved skills and confidence, teamwork and sharing of information. Staff appreciated the support and the opportunity to review emergency equipment and drugs. Recommendations based on the experience gained and the outcomes of the simulation training include that the feedback is just as important as the simulations and that clinicians need to be trained in order to facilitate simulations successfully.

Pulmonary artery catheter and veno-arterial ECMO training for cardiology fellows: evaluation of a simulation-based program

Abstract Funding Acknowledgements None. Introduction Proficiency in pulmonary artery catheter (PAC) use and extracorporeal membrane oxygenation (ECMO) therapy is crucial for delivering high-quality critical care and improving patient outcomes in cardiac intensive care units (CICUs). Both procedures are conducive to immersive simulation training. Our study focuses on evaluating the efficacy of a simulation-based training program in these specific domains for cardiology fellows. Methods Cardiology fellows participated in two blended learning courses: one on PAC and one on veno-arterial ECMO. The PAC course consisted of a pre-course test of 12 multiple-choice questions assessing knowledge of indications, contraindications, and interpretation of PAC, a 45-minute didactic lecture, followed by a case-based, hands-on simulation training session for 60 minutes. The ECMO course consisted of a pre-course test of 15 multiple-choice questions assessing indications, contraindications, ECMO physiology, and circuit management, a 30-minute didactic lecture, followed by a case-based, hands-on simulation training session. Fellows completed a multiple-choice post-course test within 72 hours post-simulation training. All test questions were designed by experts in cardiac critical care. Results A total of 18 cardiology fellows completed the PAC simulation and 16 completed the ECMO simulation. For the PAC group the average score on the pre-exam was 60%, while on the post exam, the average score increased significantly to 86%, representing a 26% increase (p=0.04). For the ECMO training, the average score on the pre-exam was 67%, and on the post exam, the average score increased substantially to 90% in the ECMO exam, there was a 23% increase in the average post-exam score compared to the pre exam was recorded (p=0.05). Conclusion Simulation-based training in PAC and ECMO has a highly positive impact on the knowledge acquisition of cardiology fellows, with statistically significant increases in average post-exam scores in both areas. These findings not only validate the value of immersive simulation-based training programs but also underscore the need for further investigation into the implementation of educational initiatives aimed at enhancing care in cardiogenic shock.

Basic life support training: Is student confidence enhanced by advanced levels of simulation?

Basic life support (BLS) is a mandatory skill for nurses. The confidence of the BLS provider should be enhanced by regular training. Traditionally, BLS training has used low-fidelity manikins, but more recent studies have suggested the use of high-fidelity manikins and alternative levels of simulation such as virtual reality. A quasi-experimental study including 125 nursing students. Data on confidence levels in various elements of BLS were collected using pre-validated questionnaires and analysed using SPSSv23. The study revealed that high-fidelity simulation had a significant impact on the BLS learner's confidence levels. The study identified the importance of high-fidelity simulation in BLS training in preparing students for clinical practice. This highlights the need for further exploration of simulation technologies, such as virtual reality, to enable students to gain the knowledge, skills, confidence and competence required to enable safe and effective practice.

Virtual reality skateboarding training for balance and functional performance in degenerative lumbar spine disease

BackgroundDegenerative lumbar spine disease (DLD) is a prevalent condition in middle-aged and elderly individuals. DLD frequently results in pain, muscle weakness, and motor impairment, which affect postural stability and functional performance in daily activities. Simulated skateboarding training could enable patients with DLD to engage in exercise with less pain and focus on single-leg weight-bearing. The purpose of this study was to investigate the effects of virtual reality (VR) skateboarding training on balance and functional performance in patients with DLD.MethodsFourteen patients with DLD and 21 age-matched healthy individuals completed a 6-week program of VR skateboarding training. The motion capture and force platform systems were synchronized to collect data during a single-leg stance test (SLST). Musculoskeletal simulation was utilized to calculate muscle force based on the data. Four functional performance tests were conducted to evaluate the improvement after the training. A Visual Analogue Scale (VAS) was also employed for pain assessment.ResultsAfter the training, pain intensity significantly decreased in patients with DLD (p = 0.024). Before the training, patients with DLD took longer than healthy individuals on the five times sit-to-stand test (p = 0.024). After the training, no significant between-group differences were observed in any of the functional performance tests (p > 0.05). In balance, patients with DLD were similar to healthy individuals after the training, except that the mean frequency (p = 0.014) was higher. Patients with DLD initially had higher biceps femoris force demands (p = 0.028) but shifted to increased gluteus maximus demand after the training (p = 0.037). Gluteus medius strength significantly improved in patients with DLD (p = 0.039), while healthy individuals showed consistent muscle force (p > 0.05).ConclusionThis is the first study to apply the novel VR skateboarding training to patients with DLD. VR skateboarding training enabled patients with DLD to achieve the training effects in a posture that relieves lumbar spine pressure. The results also emphasized the significant benefits to patients with DLD, such as reduced pain, enhanced balance, and improved muscle performance.
