High-Fidelity Contrast Reaction Simulation Training: Performance Comparison of Faculty, Fellows, and Residents.

PURPOSE: Reactions to contrast material are uncommon in diagnostic radiology, and vary in clinical presentation from urticaria to life-threatening anaphylaxis. Prior studies have demonstrated a high error rate in contrast reaction management, with smaller studies using simulation demonstrating variable data on effectiveness. We sought to assess the effectiveness of high-fidelity simulation in teaching contrast reaction management for residents, fellows, and attendings. METHODS: A 20-question multiple-choice test assessing contrast reaction knowledge, with Likert-scale questions assessing subjective comfort levels of management of contrast reactions, was created. Three simulation scenarios that represented a moderate reaction, a severe reaction, and a contrast reaction mimic were completed in a one-hour period in a simulation laboratory. All participants completed a pretest and a posttest at one month. A six-month delayed posttest was given, but was optional for all participants. RESULTS: A total of 150 radiologists participated (residents = 52; fellows = 24; faculty = 74) in the pretest and posttest; and 105 participants completed the delayed posttest (residents = 31; fellows = 17; faculty = 57). A statistically significant increase was found in the one-month posttest (P < .00001) and the six-month posttest scores (P < .00001) and Likert scores (P < .001) assessing comfort level in managing all contrast reactions, compared with the pretest. Test scores and comfort level for moderate and severe reactions significantly decreased at six months, compared with the one-month posttest (P < .05). CONCLUSIONS: High-fidelity simulation is an effective learning tool, allowing practice of "high-acuity" situation management in a nonthreatening environment; the simulation training resulted in significant improvement in test scores, as well as an increase in subjective comfort in management of reactions, across all levels of training. A six-month refresher course is suggested, to maintain knowledge and comfort level in contrast reaction management.

Utilization of exploration-based learning and video-assisted learning to teach GlideScope videolaryngoscopy.

BACKGROUND: GlideScope (GS) is used in pediatric endotracheal intubation (ETI) but requires a different technique compared to direct laryngoscopy (DL). PURPOSES: This article was written to evaluate the efficacy of exploration-based learning on procedural performance using GS for ETI of simulated pediatric airways and establish baseline success rates and procedural duration using DL in airway trainers among pediatric providers at various levels. METHODS: Fifty-five pediatric residents, fellows, and faculty from Pediatric Critical Care, NICU, and Pediatric Emergency Medicine were enrolled. Nine physicians from Pediatric Anesthesia benchmarked expert performance. Participants completed a demographic survey and viewed a video by the GS manufacturer. Subjects spent 15 minutes exploring GS equipment and practicing the intubation procedure. Participants then intubated neonatal, infant, child, and adult airway simulators, using GS and DL, in random order. Time to ETI was recorded. RESULTS: Procedural performance after exploration-based learning, measured as time to successful ETI, was shorter for DL than for GS for neonatal and child airways at the.05 significance level. Time to ETI in adult airway using DL was correlated with experience level (p =.01). Failure rates were not different among subgroups. CONCLUSIONS: A brief video and period of exploration-based learning is insufficient for implementing a new technology. Pediatricians at various levels of training intubated simulated airways faster using DL than GS.

Simulation-based training in brain death determination.

BACKGROUND: Despite straightforward guidelines on brain death determination by the American Academy of Neurology (AAN), substantial practice variability exists internationally, between states, and among institutions. We created a simulation-based training course on proper determination based on the AAN practice parameters to address and assess knowledge and practice gaps at our institution. METHODS: Our intervention consisted of a didactic course and a simulation exercise, and was bookended by before and after multiple-choice tests. The 40-min didactic course, including a video demonstration, covered all aspects of the brain death examination. Simulation sessions utilized a SimMan 3G manikin and involved a complete examination, including an apnea test. Possible confounders and signs incompatible with brain death were embedded throughout. Facilitators evaluated performance with a 26-point checklist based on the most recent AAN guidelines. A senior neurologist conducted all aspects of the course, including the didactic session, simulation, and debriefing session. RESULTS: Ninety physicians from multiple specialties have participated in the didactic session, 38 of whom have completed the simulation. Pre-test scores were poor (41.4 %), with attendings scoring higher than residents (46.6 vs. 40.4 %, p = 0.07), and neurologists and neurosurgeons significantly outperforming other specialists (53.9 vs. 38.9 %, p = 0.003). Post-test scores (73.3 %) were notably higher than pre-test scores (45.4 %). Participant feedback has been uniformly positive. CONCLUSION: Baseline knowledge of brain death determination among providers was low but improved greatly after the course. Our intervention represents an effective model that can be replicated at other institutions to train clinicians in the determination of brain death according to evidence-based guidelines.

Theoretical foundations of learning through simulation.

Health care simulation is a powerful educational tool to help facilitate learning for clinicians and change their practice to improve patient outcomes and safety. To promote effective life-long learning through simulation, the educator needs to consider individuals, their experiences, and their environments. Effective education of adults through simulation requires a sound understanding of both adult learning theory and experiential learning. This review article provides a framework for developing and facilitating simulation courses, founded upon empiric and theoretic research in adult and experiential learning. Specifically, this article provides a theoretic foundation for using simulation to change practice to improve patient outcomes and safety.

The 3D model of debriefing: defusing, discovering, and deepening.

The experiential learning process involves participation in key experiences and analysis of those experiences. In health care, these experiences can occur through high-fidelity simulation or in the actual clinical setting. The most important component of this process is the postexperience analysis or debriefing. During the debriefing, individuals must reflect upon the experience, identify the mental models that led to behaviors or cognitive processes, and then build or enhance new mental models to be used in future experiences. On the basis of adult learning theory, the Kolb Experiential Learning Cycle, and the Learning Outcomes Model, we structured a framework for facilitators of debriefings entitled "the 3D Model of Debriefing: Defusing, Discovering, and Deepening." It incorporates common phases prevalent in the debriefing literature, including description of and reactions to the experience, analysis of behaviors, and application or synthesis of new knowledge into clinical practice. It can be used to enhance learning after real or simulated events.

Simulation-based training delivered directly to the pediatric cardiac intensive care unit engenders preparedness, comfort, and decreased anxiety among multidisciplinary resuscitation teams.

OBJECTIVES: Resuscitation of pediatric cardiac patients involves unique and complex physiology, requiring multidisciplinary collaboration and teamwork. To optimize team performance, we created a multidisciplinary Crisis Resource Management training course that addressed both teamwork and technical skill needs for the pediatric cardiac intensive care unit. We sought to determine whether participation improved caregiver comfort and confidence levels regarding future resuscitation events. METHODS: We developed a simulation-based, in situ Crisis Resource Management curriculum using pediatric cardiac intensive care unit scenarios and unit-specific resuscitation equipment, including an extracorporeal membrane oxygenation circuit. Participants replicated the composition of a clinical team. Extensive video-based debriefing followed each scenario, focusing on teamwork principles and technical resuscitation skills. Pre- and postparticipation questionnaires were used to determine the effects on participants' comfort and confidence regarding participation in future resuscitations. RESULTS: A total of 182 providers (127 nurses, 50 physicians, 2 respiratory therapists, 3 nurse practitioners) participated in the course. All participants scored the usefulness of the program and scenarios as 4 of 5 or higher (5 = most useful). There was significant improvement in participants' perceived ability to function as a code team member and confidence in a code (P < .001). Participants reported they were significantly more likely to raise concerns about inappropriate management to the code leader (P < .001). CONCLUSIONS: We developed a Crisis Resource Management training program in a pediatric cardiac intensive care unit to teach technical resuscitation skills and improve team function. Participants found the experience useful and reported improved ability to function in a code. Further work is needed to determine whether participation in the Crisis Resource Management program objectively improves team function during real resuscitations.

Simulation at the point of care: reduced-cost, in situ training via a mobile cart.

OBJECTIVE: The rapid growth of simulation in health care has challenged traditional paradigms of hospital-based education and training. Simulation addresses patient safety through deliberative practice of high-risk low-frequency events within a safe, structured environment. Despite its inherent appeal, widespread adoption of simulation is prohibited by high cost, limited space, interruptions to clinical duties, and the inability to replicate important nuances of clinical environments. We therefore sought to develop a reduced-cost low-space mobile cart to provide realistic simulation experiences to a range of providers within the clinical environment and to serve as a model for transportable, cost-effective, widespread simulation-based training of bona-fide workplace teams. DESIGN: Descriptive study. SETTING: A tertiary care pediatric teaching hospital. MEASUREMENTS AND MAIN RESULTS: A self-contained mobile simulation cart was constructed at a cost of $8054 (mannequin not included). The cart is compatible with any mannequin and contains all equipment needed to produce a high quality simulation experience equivalent to that of our on-site center--including didactics and debriefing with videotaped recordings complete with vital sign overlay. Over a 3-year period the cart delivered 57 courses to 425 participants from five pediatric departments. All individuals were trained among their native teams and within their own clinical environment. CONCLUSIONS: By bringing all pedagogical elements to the actual clinical environment, a mobile cart can provide simulation to hospital teams that might not otherwise benefit from the educational tool. By reducing the setup cost and the need for dedicated space, the mobile approach provides a mechanism to increase the number of institutions capable of harnessing the power of simulation-based education internationally.

Toward a new paradigm in hospital-based pediatric education: the development of an onsite simulator program.

OBJECTIVE: The low incidence of crises in pediatrics, coupled with logistic issues and restricted work hours for trainees, hinders opportunities for frequent practice of crisis management and teamwork skills. We hypothesized that a dedicated simulator suite contiguous to the intensive care unit (ICU) would enhance the frequency and breadth of critical-incident training for a range of clinicians. DESIGN: Descriptive study. SETTING: A tertiary-care pediatric teaching hospital. MEASUREMENTS AND MAIN RESULTS: A realistic pediatric simulator suite was constructed 100 feet from the ICU, at a total base cost of $290,000. The simulation room is an exact replica of an ICU bed space, incorporating high-fidelity mannequin simulators. To capture an even wider audience, a portable unit was also created. Leaders from seven departments-critical care, cardiac intensive care, emergency medicine, transport medicine, anesthesia, respiratory care, and general pediatrics-completed instructor training to ensure effective debriefing techniques. Pediatric staff, including 100% of critical care fellows, 86% of nurses, 90% of respiratory therapists, and 74% of pediatric house staff, participated in >1500 learning encounters per year. All individuals were trained during their normal workday in the hospital. Courses in crisis resource management, skills acquisition, annual review, orientation, and trauma management (1,116, 98, 90, 60, and 60 encounters per year, respectively) were all designed by a multidisciplinary committee to ensure goal-directed education to a range of audiences. Annual costs were on par with those at other centers (approximately 44 dollars per trainee encounter). CONCLUSIONS: An onsite and comprehensive simulation program can significantly increase the opportunities for clinicians from multiple disciplines, in the course of their daily routines, to repetitively practice responses to pediatric medical crises. After an initial capital investment, the training appears to be cost-effective. Hospital-based simulator suites may point the way forward as a new paradigm for the effective education of today's busy clinicians.
