To identify and review the currently available simulators for prostate surgery and to explore the evidence supporting their validity for training purposes.

The Relationship Between Technical And Nontechnical Skills Within A Simulation-Based Ureteroscopy Training Environment

OBJECTIVE Little integration of technical and nontechnical skills (e.g., situational awareness, communication, decision making, teamwork, and leadership) teaching exists within surgery. We therefore aimed to (1) evaluate the relationship between these 2 skill sets within a simulation-based environment and (2) assess if certain nontechnical skill components are of particular relevance to technical performance. DESIGN A prospective analysis of data acquired from a comparative study of simulation vs nonsimulation training was conducted. Half of the participants underwent training of technical and nontechnical skills within ureteroscopy, with the remaining half undergoing no training. All were assessed within a full immersion environment against both technical (time to completion, Objective Structured Assessment of Technical Skills, and task-specific checklist scores) and nontechnical parameters (Nontechnical Skills for Surgeons [NOTSS] rating scale). The data of whole and individual cohorts were analyzed using Pearson correlation coefficient. SETTING The trial took place within the Simulation and Interactive Learning Centre at Guys Hospital, London, UK. PARTICIPANTS In total, 32 novice participants with no prior practical ureteroscopy experience were included within the data analysis. RESULTS A correlation was found within all outcome measures analyzed. For the whole cohort, a strong negative correlation was found between time to completion and NOTSS scores (r = -0.75, p < 0.001), with strong positive correlations identified when NOTSS scores were compared with Objective Structured Assessment of Technical Skills (r = 0.89, p < 0.001) and task-specific checklist scores (r = 0.91, p < 0.001). Similar results were observed when each cohort was analyzed separately. Finally, all individual nontechnical skill components demonstrated a strong correlation with all technical skill parameters, regardless of training. CONCLUSIONS A strong correlation between technical and nontechnical performance exists, which was demonstrated to be irrespective of training received. This may suggest an inherent link between skill sets. Furthermore, all nontechnical skill sets are important in technical performance. This supports the notion that both of these skills should be trained and assessed together within 1 curriculum.

Simulation-based training and assessment in urological surgery

Simulation has become widely accepted as a supplementary method of training. Within urology, the greatest number of procedure-specific models and subsequent validation studies have been carried out in the field of endourology. Many generic-skills simulators have been created for laparoscopic and robot-assisted surgery, but only a limited number of procedure-specific models are available. By contrast, open urological simulation has only seen a handful of validated models. Of the available modalities, virtual reality (VR) simulators are most commonly used for endourology and robotic surgery training, the former also employing many high-fidelity bench models. Smaller dry-lab and ex vivo animal models have been used for laparoscopic and robotic training, whereas live animals and human cadavers are widely used for full procedural training. Newer concepts such as augmented-reality (AR) models and patient-specific simulators have also been introduced. Several curricula, including one recommended within, have been produced, incorporating various different training modalities and nontechnical skills training techniques. Such curricula and validated models should be used in a structured fashion to supplement operating room training.

Simulation-Based Ureteroscopy Training: A Systematic Review

OBJECTIVE Simulation is a common adjunct to operative training and various modalities exist for ureteroscopy. This systematic review aims the following: (1) to identify available ureteroscopy simulators, (2) to explore evidence for their effectiveness using characteristic criterion, and (3) to provide recommendations for simulation-based ureteroscopy training. DESIGN The preferred reporting items for systematic reviews and meta-analysis statement guidelines were used. A literature search was performed using the PubMed, EMBASE, and Cochrane Library databases. RESULTS In total, 20 articles concerning ureteroscopy simulators were included. Overall, 3 high-fidelity bench models are available. The Uro-Scopic Trainer has demonstrated face, construct, and concurrent validity, whereas the Scope Trainer has undergone content, construct, and predictive validation. The adult ureteroscopy trainer has demonstrated face, content, and construct validity. The URO Mentor is the only available ureteroscopy virtual-reality system; 10 studies were identified demonstrating its face, content, construct, concurrent, and predictive validity. The Uro-Scopic Trainer, the Scope Trainer, and the URO Mentor have demonstrated high educational impact. A noncommercially available, low-fidelity model has demonstrated effectiveness comparable to its high-fidelity counterpart at 185 times lesser than the price of the Uro-Scopic Trainer. The use of porcine models has also been described in 3 studies but require further study. CONCLUSIONS Valid models are available for simulation-based ureteroscopy training. However, there is a lack of many high-level studies conducted, and further investigation is required in this area. Furthermore, current research focuses on the technical skills acquisition with little research conducted on nontechnical skills acquisition within ureteroscopy. The next step for ureteroscopy training is a formalized and validated curriculum, incorporating simulation, training models, development of nontechnical skills, and real-life practice.

Current Status of Simulation and Training Models in Urological Surgery: A Systematic Review.

PURPOSE Increased awareness of patient safety, advances in surgical technology and reduced working times have led to the adoption of simulation enhanced training. However, the simulators available need to be scientifically evaluated before integration into curricula. We identify the currently available training models for urological surgery, their status of validation and the evidence behind each model. MATERIALS AND METHODS MEDLINE®, Embase® and the Cochrane Library databases were searched for English language articles published between 1990 and 2015 describing urological simulators and/or validation studies of these models. All studies were assessed for level of evidence, and each model was subsequently awarded a level of recommendation using a modified Oxford Centre for Evidence-Based Medicine classification, adapted for education by the European Association of Endoscopic Surgeons. RESULTS A total of 91 validation studies were identified pertaining to training models in endourology (63), laparoscopic surgery (17), robot-assisted surgery (8) and open urological surgery (6), with a total of 55 models. Of the included studies 6 were classified Level 1b, 9 Level 2a, 39 Level 2b and 19 Level 2c. Of all the training models the URO Mentor™ was the only one to receive a level of recommendation of 1. CONCLUSIONS UroSimulation is a growing field and increasing numbers of models are being produced. However, there are still too few validation studies with a high level of evidence demonstrating the transferability of skills. Nevertheless, efforts should be made to use the currently available models in curriculum based training programs.

A Novel Cadaveric Simulation Program in Urology

OBJECTIVE To evaluate the urology human cadaver training program developed by the British Association of Urological Surgeons. DESIGN This prospective, observational comparative study recruited urology residents, with different levels of experience, in 2 sessions of a 3-day modular cadaveric operative urology training. Participants performed various procedures on fresh-frozen cadaveric specimens, as per module, supervised by certified urological surgeons. At the conclusion of each module, all residents and faculty were invited to complete an evaluation survey. SETTING The training days were hosted by the British Association of Urological Surgeons at the University of Manchester Surgical Skills and Simulation Centre. PARTICIPANTS A total of 81 urology residents were recruited, with a maximum of 14 participants attending each module, over 2 sessions. We allocated 2 participants to each cadaver with access to all necessary equipment and guidance. RESULTS A total of 102 evaluation surveys were received from the trainees and faculty; a response rate of 94%. All procedures scored a mean of 3 on 5 for face validity, which is higher than the acceptability range. Regarding content validity, participants and faculty rated all aspects ≥3 on 5. Respondents held a positive view of the cadaver sessions and believed them to be useful for learning anatomy and steps of an operation (mean = 4.54) and as a confidence booster for performing a procedure (mean = 4.33). Furthermore, it was thought that the training program significantly improved skills (mean = 4.11), gave transferrable skills for the operating room (mean = 4.21), and was feasible to be incorporated into training programs (mean = 4.29). Human cadaveric simulation was rated as the best mode of simulation-based training for all the procedures in the curriculum. CONCLUSIONS This study on cadaveric simulation training demonstrated face and content validities. It also showed feasibility, acceptability, a high value for educational influence and cost-effectiveness for cadaveric simulation. A simulation-based training pathway has been proposed for effective procedural training in urology.

Face and Content Validation of the Prostatic Hyperplasia Model and Holmium Laser Surgery Simulator

OBJECTIVE Although a number of simulators have been introduced for prostate surgery, none have undergone validation for holmium laser enucleation of the prostate training. This study was carried out to assess the face and content validities as well as feasibility and acceptability of the new prostatic hyperplasia model and prostate surgery simulator for holmium laser enucleation of the prostate. DESIGN This is a prospective, observational, and comparative study. Participants were given a 30-minute video tutorial followed by a 45-minute simulation session, with one-to-one mentoring. A survey with qualitative and quantitative fields was used to evaluate their experience. SETTING This study was carried out in a 2-day modular teaching course hosted by the Holmium User Group at Cambridge University Hospitals, UK, and during the British Association of Urological Surgeons 2013 Annual Meeting. PARTICIPANTS A total of 36 participants comprising 13 urology trainees and 23 senior urologists of varying levels from all around the globe were recruited. RESULTS Overall, 87% of the participants believed that holmium laser enucleation of the prostate was an effective method of treatment, simulation-based training, and assessment essential for patient safety and 84% believed a validated simulator would be useful for training. Of the participants, 97% agreed that the simulation should be implemented into training programs and only 31% felt it should be part of accreditation. Participants ranked all components of the simulator greater than 7 of 10 on a global rating scale and believed it was a feasible and acceptable method of training and assessment. CONCLUSIONS The new simulator for holmium laser enucleation of the prostate has been demonstrated to be useful as a training tool. This study has established face and content validities of the simulator. Senior and trainee urologists believed the simulator was an acceptable tool for training and assessment and its use feasible for novice trainees to acquire skills and knowledge to a predetermined level of proficiency.

The role of simulation in urological training - A quantitative study of practice and opinions.

INTRODUCTION Over the past few decades, simulation-based training has rapidly been adopted by many centres for effective technical and non-technical skills training, as a supplementary method to traditional operating room experience. The aim of this study is to assess the current practice in training and seek opinion regarding the future role of simulation in urological training. METHODS A cross sectional survey was designed and distributed amongst expert and trainee urological surgeons. The survey consisted of twenty-two questions that were split into three sections; Introduction (6), Technical Skills training in urology (10) and Non-technical skills training in urology (6). RESULTS A total of 91 residents and 172 specialists completed the survey. In both groups, there was an agreed consensus that laparoscopic training and exposure was insufficient as only 21% of trainees and 23% of specialists believed that they had sufficient training in this area. Furthermore, both groups lacked simulation-based training in common urological procedures including nephrectomy (62%), cystoscopy (69-74%), ureteroscopy (47-59%), transurethral resection of the prostate (56-65%) and percutaneous renal surgery (76-73%). 90% of trainees and 70% of specialists believed (agreed and strongly agreed) that there is a role for non-technical skills simulation in urological training. CONCLUSIONS Simulation training has been under-used thus far and trainees face an uphill challenge to enhance their skills and technical abilities in the operating room. Simulation is recommended by both trainees and specialists and may represent one of the solutions to the challenges of safe and effective urology procedural training.

A review of wearable technology in medicine

With rapid advances in technology, wearable devices have evolved and been adopted for various uses, ranging from simple devices used in aiding fitness to more complex devices used in assisting surgery. Wearable technology is broadly divided into head-mounted displays and body sensors. A broad search of the current literature revealed a total of 13 different body sensors and 11 head-mounted display devices. The latter have been reported for use in surgery (n = 7), imaging (n = 3), simulation and education (n = 2) and as navigation tools (n = 1). Body sensors have been used as vital signs monitors (n = 9) and for posture-related devices for posture and fitness (n = 4). Body sensors were found to have excellent functionality in aiding patient posture and rehabilitation while head-mounted displays can provide information to surgeons to while maintaining sterility during operative procedures. There is a potential role for head-mounted wearable technology and body sensors in medicine and patient care. However, there is little scientific evidence available proving that the application of such technologies improves patient satisfaction or care. Further studies need to be conducted prior to a clear conclusion.
