Simulation-Based Education







Creating different learning experiences using programmable patient simulators as an educational technique


Simulation is a technique used in health care education to replicate the essential aspects of a clinical situation in an academic setting so that the participant can learn to examine, assess, and manage the event more effectively when it occurs in clinical practice.1,2 Although the use of patient simulators (e.g., role players and standardized patients) has been a long-standing practice in physical therapist education, the use of programmable patient simulators is relatively new. Programmable patient simulators are life-sized mannequins operated by sophisticated computer systems that control a variety of “patient” variables, such as vital signs, breath sounds, heart tones, and vocalizations. When programmable patient simulators are incorporated into a realistic setting (e.g., mock critical care unit with all of the lines, tubes, alarms, and monitors), the simulated environment and experience become realistic, immersive, and uncertain for the participant learning to work with complex patients or manage a clinical event.



Institute of medicine report on health care education competencies


The Institute of Medicine 2003 report,3 Health Professions Education: A Bridge to Quality, challenges educators across all health care professions to redesign curriculum and restructure clinical learning experiences based on five competency areas: patient-centered care, interdisciplinary teams, evidence-based practice, quality improvement, and informatics. Competencies are defined in the report3 as the “habitual and judicious use of communication, knowledge, technical skills, clinical reasoning, emotions, values and reflection in daily practice.” Simulation using programmable patient simulators provides an opportunity to address, practice, and assess all five of these competency areas in the context of a realistic patient care setting. Articles in the nursing literature have shown that the use of programmable patient simulators had a positive impact on participant learning and improved performance on subsequent simulation experiences.411 Studies with medical students have shown that there was significant improvement in critical assessment skills, performance, and retention of information when training included the use of programmable patient simulators.1215




Institute for healthcare improvement report to improve patient safety


The Institute for Healthcare Improvement published a set of goals in 2006 designed to improve patient safety.17 These goals set improved communication and teamwork among health care professionals during emergency situations as a priority. The Institute specifically focused on the use of programmable patient simulators as a means to improve communication and teamwork among health care professionals. Teamwork training is of particular importance because patient care has become more complicated and requires a multidisciplinary approach, yet education of health care professionals is still often provided in “silos” within each discipline.18 Studies with Medical and Nursing students demonstrated improved emergency team performance when high-fidelity simulation was incorporated into their training.19,20 There are a number of studies in the nursing and medical literature supporting the efficacy of programmable patient simulation for improving health care education outcomes and multidisciplinary team management of medical emergencies.4,5,12,19,2123



Features of high-fidelity simulation and programmable patient simulators



Realism, immersion, and integration


Fidelity is a term used to express the degree of realism present in the programmable patient simulator or the simulation. Programmable patient simulators have a variety of observable and clinical features available that add to the degree of realism present in the simulation. High-fidelity simulators have observable features that include the capacity for chest wall movements, pupils that are reactive to light, eyelids that blink, and the ability to converse and vocalize symptoms. Clinical features include breath sounds, heart tones, bowel sounds, and a library of normal and abnormal sounds for each. Simulators can be connected to a patient monitor that displays a variety of parameters in real time, such as electrocardiogram (ECG) data, blood pressure, and oxygen saturation among others. (Figure 6-1).



The features available in programmable patient simulators provide the operator with the ability to design scenarios that realistically replicate complex medical conditions and situations. For example, a “patient” can be stable when the simulation participant enters the room but develop chest pain and ECG changes associated with the onset of an acute myocardial infarction during the intervention. When the programmable patient simulator is incorporated into a high-fidelity setting with lines, tubes, alarms, and monitors, the simulated environment and experience becomes realistic, immersive, and unpredictable for the participant learning to work with complex patients or manage a clinical event. Simulation forces the participant to examine, assess, and integrate information in real time while witnessing the consequences of their decisions and actions.



Transformational learning and high-fidelity simulation


The goal of transformational learning is to develop learners with the ability to evaluate, interpret, and perform autonomous thinking, not simply memorize materials or assume the beliefs and judgments of an authority figure. Autonomous thinking is fundamental to professional practice in which each client presents with unique needs and requires creation of a plan of intervention developed in light of best practice guidelines (see Chapter 3 for additional information regarding metacognitive skills and reflective processes that facilitate autonomous thinking and transformational learning). Transformational learning affects the learner’s frame of reference. Internal frames of reference are an adult learner’s acquired “coherent body of experience—associations, concepts, values, feelings, conditioned responses” through which they interpret life experiences.24 These frames of reference, based on knowledge, assumptions, and feeling, determine the actions people will take. The debriefing process is designed to uncover and analyze the participant’s frames of reference that lead to the action taken (see later section, Debriefing Process). The discovery and analysis of a participant’s frame of reference helps learners understand how their frame of reference was used to make a clinical decision as well as learn to scrutinize and transform that frame of reference in order to improve their professional performance on an ongoing basis.


Simulation has the potential to be a transformational learning experience that permanently changes the participant’s view of the situation. Programmable patient simulation actively engages the participant in a student-centered learning environment. The simulation demands that they apply their subject mastery and clinical skills in the context of a realistic, unpredictable patient care situation. Learners “see” and “feel” the consequences of their actions, as well as their inactions, without compromising patient safety.


Simulation participants should go through a debriefing session following the simulation experience (see later section, Debriefing Process). The debriefing session challenges the learner to reflect on and explain their frame(s) of reference—that is, the assumptions and knowledge they used to reach their clinical decisions. A well-designed debriefing session fosters a discourse among participants regarding their frame of reference as well as how they could interpret the situation differently next time in order to improve their performance—that is, the debriefing session can transform the participants’ frame of reference and their clinical behavior.



Performance-based assessments with high-fidelity simulation



Preparing the learner for the simulation experience


Effective high-fidelity simulation experiences that enable performance-based assessment of the specific knowledge, skills, and attitudes the learner is to achieve begin with development of targeted learning objectives and assignment of presimulation didactic content on which the simulation scenario is based. Ideally, simulation scenarios should be limited to three to four broad objectives, run 15 minutes or less, and include an immediate debriefing process that is equal to or double the time of the scenario.2125 More extensive objectives and longer simulations can overwhelm participants and lead to less focused debriefing discussions. Each objective can address several “essential or critical behaviors” the participant should perform. For example, Figure 6-2 illustrates a specific but broad objective for the participants. The critical behaviors listed in Figure 6-2 are what the participant is assessed on in the simulation to demonstrate understanding of the objective. Depending on the level of learner (novice, competent, expert), the facilitator may choose whether or not to provide the critical behaviors checklist as part of the simulation preparation. For members of the simulation group who are observing instead of participating at the bedside, the critical behaviors checklist can be an effective tool for helping formulate feedback and reinforcing the content of the objective.



Preparation for the simulation experience may take the form of readings, quizzes, concepts maps, video review of skills, laboratories, or practice on skill task trainers. This enables the participants to enter the simulation learning environment with the prerequisite knowledge and exposure to skills they are expected to synthesize in a patient-centered scenario.26 In addition, participants need to be oriented to the simulator equipment so that lack of familiarity with the functions of the simulator does not affect their ability to perform.27 Preparing students with the simulation objectives, didactic content, and prior practice with skills establishes a baseline for formative learning from which the student can demonstrate an ability to accomplish higher-order activities, such as application and integration of the material during the simulation experience. In addition, simulation enables the facilitator to immediately observe gaps in the ability of a student to apply and integrate knowledge, skill, or convey appropriate attitudes during the simulation, which can then be addressed and clarified in the debriefing session. Subsequent simulation experiences that repeat the scenario or apply the same clinical concepts in a new scenario can form the basis for performance-based assessment using simulation.



Simulation learning environment


The tone the facilitator sets for the simulation experience and subsequent debriefing is pivotal to participant learning. Depending on the size of the learner group, participants may be divided into two groups of “active participants” and “observers.” To enhance realism, the scenario should involve the number of active participants that would most closely mimic what is found in clinical practice, and the roles should be rotated in subsequent simulations.21


Performing in front of peers and a facilitator can be very stressful to participants.21,25,28,29 Therefore, establishing a safe learning environment and a relationship of trust among the facilitator and participants is essential.27,30 This involves understanding the ground rules for respectful communication and confidentiality. Maintaining confidentiality about what happens in the simulation learning experience is an integral part of creating an environment of mutual respect. Addressing any use of video, audio, or written scenario summaries created during the simulation experience is part of this process. In fostering trust, the facilitator should explain how these materials will be stored, who will have access to them, and how and when they will be destroyed. This can be reinforced by having participants and facilitators sign a confidentiality and video/audio agreement, which is used in many simulation learning centers. Creating a psychologically safe and supportive environment where the students feel respected, valued, and free to explore questions, discuss mistakes, and reflect on how to improve practice is essential if the simulation experience and debriefing process are to be successful in creating transformational learning.30,31


In addition to establishing a safe learning environment, the authenticity of the simulation can affect participant performance. Ideally, participants should wear the professional attire they would expect to wear in the clinical situation being simulated. This enhances the fidelity of the scenario and expectation of professional demeanor. Care should be given to simulator moulage and props to create as close to a real-life situation as possible.32 For example, if the participant is involved in working with a patient in the intensive care setting, then the appropriate monitoring equipment, audio alarms, invasive lines and tubes, and safety equipment should be in place (see Figure 6-1). As the “patient’s” condition changes, the participant’s recognition of or failure to respond to alarms and cues in the midst of other patient status changes can be explored in debriefing. Creating an atmosphere that mimics clinical reality allows the participant to suspend disbelief and encourages authentic engagement in the simulated experience to allow for deeper, more comprehensive performance assessment and discovery of the participant’s frames of reference that are driving their clinical decision making.30
