Creation of an optic nerve sheath diameter ultrasound model for NeuroICU education.

BACKGROUND: Using ultrasound to measure optic nerve sheath diameter (ONSD) is an emerging bedside technique to noninvasively assess intracranial pressure (ICP) in patients with brain injury. This technique is unique among bedside ultrasonography and is often performed by providers who have no formal ultrasound training. We sought to create a low-cost, 3D, reusable ONSD model to train neurology, neurosurgery, and critical care providers in measuring ICP. RESULTS: We identified 253 articles, of which 15 were associated with models and 2 with simulation. One gelatin model was reported, upon which we based our initial design. We could not validate the visual findings of this model; however, after constructing multiple beta models, the design most representative of human eye anatomy was a globe made of ballistics gel and either a 3 mm, 5 mm, or 7 mm × 50 mm 3D-printed optic nerve inserted into a platform composed of ballistics gel, all of which sat inside a 3D-printed skull. This model was used to teach ONSD measurements with ultrasound at a continuing medical education event prior to training on a live human model. CONCLUSION: A simple 3D ballistic ONSD model allows learners to practice proper hand placement and pressure, basic landmarks, and ONSD measurement prior to operating on a human eye. This model is replicable and sustainable given that the globe and platform are composed of ballistics gel.

Enhancing the Informed Consent Process Using Shared Decision Making and Consent Refusal Data from the CLEAR III Trial.

BACKGROUND: The process of informed consent in National Institutes of Health randomized, placebo-controlled trials is poorly studied. There are several issues regarding informed consent in emergency neurologic trials, including a shared decision-making process with the patient or a legally authorized representative about overall risks, benefits, and alternative treatments. METHODS: To evaluate the informed consent process, we collected best and worst informed consent practice information from a National Institutes of Health trial and used this in medical simulation videos to educate investigators at multiple sites to improve the consent process. Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage Phase III (CLEAR III) (clinicaltrials.gov, NCT00784134) studied the effect of intraventricular alteplase (n = 251) versus saline (placebo) injections (n = 249) for intraventricular hemorrhage reduction. Reasons for ineligibility (including refusing to consent) for all screen failures were analyzed. The broadcasted presentation outlined best practices for doctor-patient interactions during the consenting process, as well as anecdotal, study-specific reasons for consent refusal. Best and worst consent elements were then incorporated into a simulation video to enhance the informed consent process. This video was disseminated to trial sites as a webinar around the midpoint of the trial to improve the consent process. Pre- and post-intervention consent refusals were compared. RESULTS: During the trial, 10,538 patients were screened for eligibility, of which only three were excluded due to trial timing. Pre-intervention, 77 of 5686 (1.40%) screen eligible patients or their proxies refused consent. Post-intervention, 55 of 4849 (1.10%) refused consent, which was not significantly different from pre-intervention (P = 0.312). The incidence of screen failures was significantly lower post-intervention (P = 0.006), possibly due to several factors for patient exclusion. CONCLUSION: The informed consent process for prospective randomized trials may be enhanced by studying and refining best practices based on trial-specific plans and patient concerns particular to a study.

Word Catheter Placement for Bartholin's Gland Abscess: Applications for Clinical Practice and Simulation.

For women who present with Bartholin's abscesses, placement of a Word catheter offers a minimally invasive approach for effective management in urgent care and emergency department settings. Although the procedure is relatively simple, the frequency of placement in the ED setting varies. Provider familiarity with both the device and the procedure can be enhanced using simulation techniques. This article presents the diagnostic and treatment approaches to Bartholin's abscesses and describes in detail both low- and high-fidelity simulations for Word catheter placements.

Vasectomy Simulation Curriculum and Trainer with Enhanced Face, Content and Construct Validity.

INTRODUCTION: We assessed the face, content and construct validity of a newly created vasectomy simulation module. METHODS: Pre-simulation and post-simulation surveys quantifying simulation effectiveness, impact on confidence level and critiques of the overall design were obtained in July 2015 to assess face and content validity. Residents were subdivided based on year of residency and construct validity was ascertained via a 20-objective checklist and individual Likert score as graded by a single attending physician in a blinded fashion. RESULTS: Two medical students and 8 residents (2 Pre-Urology, 2 Uro-1, 2 Uro-2 and 2 Uro-3) were included in the analysis. The response rate was 100% (10 of 10) for the simulation exercise and all residents (100%, 8 of 8) were used in the metric data analysis. Simulation increased the confidence to perform a vasectomy independently on average 1.58 points based on pre-simulation and post-simulation questionnaire analysis (95% CI 1.09-2.89, p=0.02). Training year had a significantly positive association (overall p <0.01) with number of objectives completed. CONCLUSIONS: Our enhanced vasectomy simulation module demonstrated excellent face, content and construct validity.

A Colposcopy Trainer to Simulate Visualization and Biopsy of the Cervix.

BACKGROUND: Colposcopy is a common office procedure providing a magnified view of the cervix for the evaluation of an abnormal cytology result. Traditionally the procedure has been replicated in simulation training by using a sausage or hotdog to represent the cervix and allow for target biopsy. This is neither reusable nor sustainable. METHOD: We developed a cervix model comprised of food coloring and ballistics gel. After cooling, the surface was dotted with gel that can be activated by a black light to mimic acetowhite changes. The cervix was placed into an existing pelvic trainer and then piloted by attending physicians and resident trainees in obstetrics and gynecology and family practice. EXPERIENCE: Sixteen physicians and residents were surveyed after a simulated colposcopy. Twelve had performed colposcopies and of those, eight stated that the model was very comparable with the real procedure; four stated the model was somewhat comparable. Three had never performed a colposcopy but stated that model was very or somewhat comparable with textbook or journal photographs. CONCLUSION: Our colposcopy trainer represents continued innovation in the field of simulation while being sustainable and economic. We continue to work on enhancing our model to be even more sophisticated and offering additional training options.

Assessing the performance and satisfaction of medical residents utilizing standardized patient versus mannequin-simulated training.

BACKGROUND: Conducting simulations of rapidly decompensating patients are a key part of internal medicine (IM) residency training. Traditionally, mannequins have been the simulation tool used in these scenarios. OBJECTIVE: To compare IM residents' performance and assess realism in specific-simulated decompensating patient scenarios using standardized patients (SPs) as compared to mannequin. METHODS: Nineteen IM residents were randomized to undergo simulations using either a mannequin or an SP. Each resident in the two groups underwent four different simulation scenarios (calcium channel blocker overdose, severe sepsis, severe asthma exacerbation, and acute bacterial meningitis). Residents completed pretest and post-test evaluations as well as a questionnaire to assess the reality perception (realism score). RESULTS: Nine residents completed mannequin-based scenarios, whereas 10 completed SP-based scenarios. Improvement in the post-test scores was seen in both groups. However, there were significantly higher post-test scores achieved with SP simulations in three out of the four scenarios (P=0.01). When compared with the mannequin group, the SP simulation group showed a significantly higher average realism score (P=0.002). CONCLUSIONS: Applying SP-based specific-simulation scenarios in IM residency training may result in better performance and a higher sense of a realistic experience by medical residents.

"iTrainers"--novel and inexpensive alternatives to traditional laparoscopic box trainers.

OBJECTIVE: To evaluate the use of 2 inexpensive laparoscopic trainers (iTrainers) constructed of easily attainable materials and portable tablets (iPads). METHODS: Two different laparoscopic trainers were constructed using a cardboard box, thumbtacks, and Velcro tape (box trainer). A separate box was constructed using the same supplies with a 3-ring binder (binder trainer). An iPad was used as the camera and monitor for both trainers. A total of 10 participants, including 4 junior surgical residents, 4 senior surgical residents, and 2 surgical staff, completed 3 Fundamentals of Laparoscopic Surgery (FLS) tasks using the 2 "iTrainers." Participants then completed the same tasks on a traditional FLS box trainer. All 10 participants were asked to complete a 13-question survey after the exercises. RESULTS: All the participants (100%) had access to an "iPad" for the visualization component. The 10 participants completed all 3 tasks on all 3 trainers. Senior residents outperformed junior residents on 6 of the 9 total tasks. Attending surgeons outperformed all residents on all tasks and trainers. Survey results revealed the cardboard box "iTrainer" to be the most practical and easiest to construct. CONCLUSION: "iTrainers" are an inexpensive and easy-to-construct alternative to traditional box trainers that might have construct validity as demonstrated in this trial. The box trainer might be easier to construct and have more similarities to the FLS trainer than the binder iTrainer.

Assessment of robotic simulation by trainees in residency programs of the Southeastern Section of the American Urologic Association.

OBJECTIVES: To assess the Southeast Section of the American Urological Association (SESAUA) trainee exposure to and thoughts on robotic simulation. DESIGN: Questionnaire-based study of SESAUA residency trainees to determine their access to robotic simulation, live robotic experience to date, and opinion regarding the adequacy of current robotic training. SETTING: Three trainees from each SESAUA training program were invited to Orlando, Florida for a formal 2-day robotic training course. Day 1 was a 3-component didactic session. Day 2 involved faculty directing the trainees in set tasks on a live porcine model for 4 hours and another 4 hours on the Mimic dV-Trainer (Mimic Technologies, Inc, Seattle, WA) for directed exercises. PARTICIPANTS: Thirty-two trainees from 14 programs in the SESAUA participated in the course and filled out a 1-page, 8-item questionnaire following their simulator exposure. RESULTS: Seventeen (53.1%) trainees, including 5 urology year-3 trainees, reported never having had robotic console time. Of the trainees, 65.6% (21 of 32) had access to the Mimic dV-Trainer or Mimic "backpack" whereas 10 had no exposure to robotic simulation; 84.4% (27 of 32) felt that the simulator replicated real-life robotic console surgery and 90.6% (29 of 32) felt the simulator was helpful or would be helpful for training in their program. Trainees felt the "tubes 2" drill, which mimics a vesicourethral anastomosis, was the most difficult drill to perform. CONCLUSIONS: A majority of trainees in the SESAUA have had limited to no robotic console time. A high number of resident trainees in the SESAUA have exposure to virtual reality robotic simulation. Trainees believe that the simulator replicates real-life robotic console movements and almost all believe they would be benefit from having access to robotic simulation.

Simulation-based training for bedside assistants can benefit experienced robotic prostatectomy teams.

PURPOSE: We designed a three-phase bedside assistant training course for those involved with robot-assisted radical prostatectomy (RARP). We also examined whether an experienced RARP team (>1000 cases) would perceive benefit from this three-phase bedside assistant training course. MATERIALS AND METHODS: The 13 RARP bedside assistants were identified at our institution (three surgical technicians, two surgical assistants, four resident trainees, and four physician assistants). The course consisted of three phases that were taught at three separate morning sessions. Phase 1 focused on robot functionality. Phase 2 consisted of a step-by-step video session that focused on the assistant's role in each RARP step. Phase 3 involved three hands-on laparoscopic drills that were to be completed in a predetermined period. Pre- and postcourse questionnaires assessed learner knowledge pertaining to RARP. RESULTS: All 13 learners completed the three-phase training course. Nine of 13 learners thought this course would be beneficial, although, 9 of 13 already thought that they were good RARP assistants before the course. Ten of 13 learners were able to complete the hands-on drills in the predetermined periods. On completion of the course, every learner thought the course was beneficial and that it should be repeated annually. Twelve of 13 thought that the course made them a better assistant and that their intra-abdominal spatial orientation was greatly improved. Seven of the learners thought the hands-on drills were the most beneficial portion of the course, while the other six found the step-by-step lecture the most beneficial. CONCLUSIONS: A three-phase hands-on RARP bedside assistant training course is beneficial to and desired by an experienced RARP team at least annually.
