This article presents the rationale for the design and development of a video simulation used to teach lean thinking and workflow analysis to health services and health information management students enrolled in a course on the management of health information.
The discussion includes a description of the design process, a brief history of the use of simulation in healthcare, and an explanation of how video simulation can be used to generate experiential learning environments. Based on the results of a survey given to 75 students as part of a formative evaluation, the video simulation was judged effective because it allowed students to visualize a real-world process (concrete experience), contemplate the scenes depicted in the video along with the concepts presented in class in a risk-free environment (reflection), develop hypotheses about why problems occurred in the workflow process (abstract conceptualization), and develop solutions to redesign a selected process (active experimentation).
Key words: lean thinking, workflow analysis, process analysis, experiential learning, Kolb, video simulation, simulation, health information management
To properly implement information technology within a healthcare organization, it is important to perform workflow analysis on the processes and services that will be affected by technological changes, such as the adoption of the electronic medical record (EMR) or computerized physician order entry. Wager, Wickham-Lee, and Glaser warn that failure to perform a workflow analysis will result in “the automation of outdated and inefficient processes.”1A current trend in healthcare is to use what has been termed “lean thinking,” an approach to process improvement based on the Toyota production model.2, 3The goal of lean thinking is the continual improvement of processes and services through the identification and elimination of waste. Elimination of process waste, it is believed, will result in improved efficiency and a reduction in medical errors and healthcare costs.4In the field of health services and health information management, there is no documented evidence showing how workflow analysis is best taught to students and practitioners in the field. This article examines an innovative approach based on principles derived from educational psychology and the use of a simulation video to teach workflow analysis and lean thinking to students enrolled in a course on health information management.
Kolb’s theory of experiential learning posits that learners acquire information through concrete experience or abstract conceptualization.5Learners then transform that information into knowledge through reflective observation or active experimentation. To apply these ideas in the classroom, Kolb and Zull recommend developing instructional sequences that focus on the four touchstones of the experiential learning cycle: concrete experience, reflection, abstract conceptualization, and active experimentation.6Stated simply, an instructional sequence should present learners with a concrete experience and allow learners to reflect on that experience, develop theories and conceptualizations based on their reflections, and then create experiments that prove or disprove their theories. By actively testing out their theories, learners generate more concrete experiences, allowing for their continual progression through the learning cycle. With each progression through the cycle, learners develop knowledge of how the information presented in the classroom can be used in a real-world setting.7
Teaching Workflow Analysis and Lean Thinking
By their very nature, workflow analysis and lean thinking are abstract topics. To understand each topic, learners must deal with concepts such as value, value stream mapping, flow, pull, perfection, current state, future state, waste, and process metrics.8 These concepts are tied directly to workflow analysis. For example, for every healthcare process, the question must be asked: “How does this process add value to the customer?” Processes must be broken down into component steps using value stream mapping, with each step analyzed in terms of the value it adds to the customer. Processes must flow uninterrupted, without unnecessary wait times, and must be completed when the next step in the process is ready (pull) and always with an eye toward perfection.
In a typical learning environment, these concepts could be presented using lectures, case studies, and textual descriptions of healthcare-related processes and services. The problem with this type of instruction is that the focus is on one part of the learning cycle, namely, abstract conceptualization. What is needed is a method of instruction that provides the learner with a concrete example of a process or service that is performed within a healthcare organization; this allows them to apply the concepts of workflow analysis and lean thinking toward the improvement of that process in a safe and nonthreatening environment.
The emphasis on concrete experience is important because, as Nichols points out, we all learn through our senses: hearing, sight, taste, touch, and smell.9The most important of these, according to Groombridge, is sight.10Zull explains that the word teacher is derived from the old English word techen, which meant “to show,” and he notes that to help students understand an idea, a concept, or a principle, we need to provide them with an image of how the subject under study manifests itself in real life.11This fact takes on deeper meaning because “our concrete experience of seeing is retained in a concrete form of physically connected neurons in the brain.”12Concrete experience is important because it “contains much of the information we need for understanding, because it produces images for our brains to analyze, rearrange, manipulate, and turn into action.”13Without images, and with only the use of words, understanding a concept, idea, or principle is difficult because students cannot see what the teacher is trying to show them.
Helping Students to See
To provide students with the concrete experiences they need to learn to perform workflow analysis and implement lean thinking, the educational strategy known as simulation was selected. Hanna defines a simulation as “a role playing situation that relates to real life roles that may or may not use materials such as videotapes, film, tape recorders, or computers.”14仿真应用领域的美第奇ne and nursing since 1930 and manifest themselves in the following formats: training models that resemble anatomical parts of the body, mannequins capable of simulating various complex medical scenarios, role play, and video-based presentations.15-19The five most important advantages of using simulation as an educational strategy include that it creates learning environments that promote experiential learning; allows for learning to develop without fear of personal failure; provides greater learner control over the environment, which promotes independence and skill development; mimics the clinical environment students will encounter upon graduation; and creates a role-playing situation that allows students to perform real-life roles.
The decision to use a video simulation was made based on the fact that video can be saved to a CD-ROM or DVD and easily distributed to students. For distance learners, the video can be posted to a course presentation tool such as Blackboard or Sakai. Individual students or groups of students can then watch the video simulation in class or outside of class, alone or while working in groups. Furthermore, with a video simulation, students have more control over the presented concrete experience. They can use a tool such as Windows Media Player to rewind, go forward, and repeat a section of the video simulation to study key moments in the presentation as they learn to use presented concepts to redesign the simulated workflow.20, 21
As a tool for presenting simulations, video, according to Brown, has been used in three broad categories: as a substitute for live instruction, as an adjunct to other teaching methods, and as a means for providing skills training to healthcare professionals.22This last category, skills training, made video simulation the obvious choice for this project. In the past, video simulations have been used to teach manipulative skills such as taking blood pressure; to develop interpersonal skills such as communications counseling, interviewing, and teaching; to encourage role play; and to show examples of poor and model practices.23-25For this project, video simulations were created to demonstrate the wrong way and the right way to perform a specific process. Students would first view the poor performance, then redesign the process, and finally view the correct way to perform the process as a measure of determining how well they performed the workflow process redesign.
Developing the Video Simulation
为了开发视频模拟，Chang和Hirsch的生产过程被采用了。26This process can be broken down into three stages: pre-production, production, and post-production. The pre-production stage included topic selection, preparation of the script, budget planning, personnel considerations, and identification of the required equipment.
To identify a suitable process that could be simulated and used to teach workflow analysis, the main author consulted the staff at the East Carolina University College of Nursing Simulation Laboratory. After an initial meeting with the director of the simulation laboratory, the main author reviewed an article by Catchpole that described the process of handing over a patient from surgery to intensive care and the techniques used to improve the safety and quality of this process.27At first blush, this seemed like a good process to simulate. However, several other factors needed to be considered. Those factors included that the process must be stimulating to students, be subject to Joint Commission standards and other regulatory requirements, provide an opportunity for students to theorize how information technology could be implemented to improve the selected process, and allow actors to make both subtle and egregious mistakes; furthermore, expertise must be available to develop a simulation of the process that exhibits fidelity, face validity, and visual fidelity.28在这种情况下，富达与经验的真实过程有关。由于许多学生没有在医疗保健环境中工作，因此为他们提供高视觉和现实世界忠诚度的模拟很重要。
After further discussion with the staff of the simulation laboratory, a decision was made to simulate the process of performing a Norwood procedure for the correction of a congenital heart defect on an infant and the subsequent transfer of the infant from the surgical unit to a neonatal intensive care unit (NICU). Selection of this process was advantageous because simulation of a surgery and transfer of an infant to a NICU would be stimulating to many of the students in the class; this would likely be their first time seeing what goes on in a surgical suite and witnessing how healthcare professionals interact with each other. Second, this process would introduce them to the Joint Commission’s Situation-Background-Assessment-Recommendation (SBAR) standard of reporting between health professionals, as well as the universal protocol standard.29第三,学生们会得到一个机会theorize how to implement information technology, namely the electronic health record, to document what occurs during the surgery and subsequent transfer. Fourth, this process would allow the actors to make mistakes, such as contaminating the sterile field or cutting off the baby’s identification bands, that need to be identified by students and eliminated from the transfer process altogether. Fifth, because the director of the simulation laboratory was a former emergency department nurse and a member of her staff was a former director of a neonatal intensive care unit, expertise was available to design a video simulation that would have high fidelity (authenticity) and face validity, and because the simulation laboratory contained a fully functional operating room and NICU, the simulation would have visual fidelity (a realistic visual scenario).
Preparation of the Script
The script for the video simulation was developed by the director of the simulation laboratory and the former director of a local hospital NICU. The script included the following roles: floating nurse, scrub nurse, two operating room nurses, nurse anesthesiologist, doctor observer, and heart surgeon.
Budget and Personnel Considerations
The simulation laboratory services are free to faculty in East Carolina University’s College of Nursing and College of Allied Health Sciences. Each part in the scenario was played by a faculty or staff member of the simulation laboratory, a senior nurse anesthesia student in the College of Nursing, or a resident from the university’s medical school. Before the video was produced, all personnel taking part in the simulation reviewed the script several times and practiced their roles in several rehearsals.
The equipment required for the video simulation included the surgical room, the neonatal intensive care unit, an infant simulator, a respirator, a chest tube, an intravenous line and pumps, patient monitoring equipment, and an isolette.
Production and Post-production
The video simulation was filmed by an instructional technologist assigned to the College of Nursing simulation laboratory. This individual was also responsible for editing and distributing the video in CD-ROM, DVD, and Windows Media video (wmv) format.
Using the Video Simulation in a Course on Health Information Management
Health Information Management is a required senior-level course for all health services management and health information management majors. The course is taught by one faculty member to students in either a face-to-face or distance learning format. Students who choose the distance learning format interact with the instructor using Blackboard and the Centra learning platform. Centra allows the instructor and students to come together to form a virtual classroom where all parties can communicate in real time using video, text messaging, voice, a whiteboard, shared computer applications, and other interactive tools.
使用视频模拟结束时发生the semester after students had been introduced to the following topics: what a health information system is, what the components of a health information system are, change management, acquisitions, implementation, and security. Before the instruction on workflow analysis, students were given several items to supplement the video simulation experience. The first item was a 38-page workbook prepared by the instructor. The workbook contained explanations and examples of key concepts related to lean thinking. These concepts included discussions on value, the value stream, flow, pull, and perfection. The workbook also contained a step-by-step guide to value stream mapping. Value stream mapping is the technique students would use to perform workflow analysis to redesign the infant transfer process depicted in the video simulation. Finally, the workbook presented a discussion on waste (information, process, environment, people) and examples of the types of waste that can be found in processes and services within a healthcare organization. Students were given a CD-ROM that contained the infant transfer video simulation (19 minutes in length) and a handout explaining the procedures taking place in the video. This handout contained snapshots of the individuals in the video, the roles they played, and two peer-reviewed journal articles that explained the SBAR procedure and the universal protocol. Finally, students were provided handouts on which to record the errors they identified in the video. Identification of errors would provide a means for students to identify the types of waste found in the process and reflect on ways to improve the infant transfer process.
Facilitation of Learning
Before viewing the video simulation, students received a lecture on lean thinking and value stream mapping. Students were then divided into groups. Once in groups, students were instructed to watch the video simulation and identify the errors in the infant transfer. For each identified error, students were asked to identify the type of waste the error represented. For example, one identified error was a nurse not wearing surgical gloves in the operating room. This is a type of environmental waste because it endangers the safety of the patient. Once each group had time to identify the errors in the video simulation, the class came together as a group to debrief. During this debriefing period, students were asked to identify the major problems with the infant transfer. Identified issues included safety, lack of training, lack of adherence to procedures and regulations (SBAR), improper staffing issues, and lack of leadership. Students went back into their groups to identify all the steps in the infant transfer process. Group responses were placed on a whiteboard, and the class came to consensus on the steps in the transfer process (附录a). In value stream mapping, this is known as defining the current state. Students then went back into their groups charged with the task of creating the future state, or a depiction of how the process can be improved. The future state depicted by the class can be found in附录b。
To measure the impact that the video simulation had on student learning, a survey was administered to 75 students. The survey asked students to respond to the following questions:
- What was your initial reaction to the transfer video?
- Do you think the transfer video helped you learn about lean thinking and workflow analysis? Please explain.
- Do you think the transfer video assignment prepared you to perform workflow analysis in the future?
- Do you have any suggestions for improving this assignment?
共有75名学生完成了course, with 70 (93 percent) completing the survey. A content analysis was performed on the responses.30
Responses following a specific pattern were grouped together under a common theme. The themes emanating from each question are identified and explicated inAppendix C。
Based on survey responses, 85 percent of the students felt that the video simulation helped them learn about lean thinking and workflow analysis. Regarding future roles, 69 percent of the students felt the video simulation prepared them for potential workflow analysis assignments by helping them to visualize, think more deeply, and more easily identify the underlying steps within a process. Negative feelings toward the visual simulation were minimal: 7 percent of the respondents felt that the video simulation did not help them learn about workflow analysis and lean thinking, while a separate 4 percent felt that the video simulation did not prepare them for future workflow analysis assignments.
Of the themes identified in Appendix C, the authors focused on the categories related to the reactions, learning, and improvements.
Under most circumstances when a learning environment creates feelings of uncertainty, confusion, chaos, and shock among learners, the first reaction of most educators would be to return to the drawing board. However, in this instance, the designers of the video simulation were happy to learn of these results because the goal of simulation is to place the learner in a real-life situation. The simulation of real-life situations, according to Satish and Krishnamurthy, “means that the subject experiences volatility, uncertainty, delayed feedback and ambiguity with inadequate information, which are part of everyday decision making.”31The design team felt strongly that students would benefit from being placed in a highly chaotic, ambiguous learning environment because the environment was risk free. Students could take chances, make mistakes, and learn from those mistakes. In many classrooms where instruction focuses on learning abstract conceptualizations, students never have this opportunity, and their only real-world experience comes on their first day on the job, where mistakes can be deadly. Finally, the learning environment created by video simulation provided an opportunity for students to develop their critical thinking skills. These skills, as Halpern notes, come into play “whenever people grapple with complex issues and messy ill-defined problems.”32
Another major theme based on student reactions to the video was their feelings regarding staff actions. Students expressed surprise regarding the behaviors exhibited by the staff in the video. However, when one considers that the number of deaths due to medical errors occurring in the United States is estimated to be between 44,000 and 98,000 per year, it would not seem realistic to portray the operating room as a mistake-free environment.33视频中出现的行为,从wrong medication being delivered to the operating room, to the nurse pulling up her surgical gown to retrieve a pair of scissors from her pants pocket to remove the baby’s identification bands, were included in the simulation as a conscious effort by the design team to display actions that they have witnessed in healthcare organizations. The students’ feelings toward both the video and the staff behaviors serve as evidence that the design team was able to meet the goal of creating a visually stimulating simulation that captured students’ attention: students were made to think deeply as to whether the actions portrayed in the video simulation could or, more importantly, should take place in a healthcare organization. This will be a very important skill for students to possess as they enter the work force as health service and health information managers.
The focus of the second and third survey questions was to determine whether the video simulation helped students learn the skills associated with lean thinking and workflow analysis and whether they would be able to apply those skills to future workflow problems. One goal for the video simulation was to create an experiential learning environment within the classroom. To satisfy this goal, the video simulation would need to provide students with a concrete example of a workflow process so that students could envision the process, reflect on it, develop abstractions (hypotheses) based on what they viewed, and then actively experiment on selected hypotheses in hopes of improving the process. A common theme emanating from responses to both questions was that of visualization. Students felt that the video simulation allowed them to visualize the process, manipulate the process, and then develop a solution to improve the process. Evidence that the video simulation helped students to progress through the stages of Kolb’s learning cycle can be found in the following quote:
I do think that the transfer video [concrete experience] helped me learn more about lean thinking and workflow analysis because I had to go back through the notes on lean thinking. This enabled me to get a better grasp [active reflection] on what I was looking for in the video, and I was able to put the knowledge [abstract conceptualization] I gained from rereading the notes to better use. It helped me to identify [active experimentation] more mistakes [concrete experience] in the video.
Other evidence that the video simulation promoted student learning include the themes of learning (30 percent), preparation (24 percent), and thinking (12 percent). A small minority of students, 7 percent (question 2) and 4 percent (question 3), did not feel that they benefited from the video simulation.
为了改善教室中视频模拟的使用，学生们表示需要更多的临床信息，以帮助他们处理演示文稿中的内容。这些评论令人困惑，原因是本研究的作者有几个原因。首先，视频模拟本质上并非过于临床。学生们目睹了发生的模拟手术，随后婴儿从外科套件到NICU部门进行了移动。在此过程中，工作人员犯了几个错误来污染手术室的无菌环境，表现出对如何操作隔离的人缺乏了解，并执行了不当的患者交接程序。第二个问题是向参加卫生服务和健康信息管理计划的学生教授重要概念的方式。是否应该更加重视批判性思维技能的发展，以帮助学生解决不定期，模棱两可和信息贫困的问题？正如哈珀（Halpern）解释的那样，对问题的批判性思考，就像在现实世界中的思考一样，“本质上是努力的”，要求学生刻意和激烈。34Because students were supplied with a workbook, a handout, and journal articles that provided the information they would need to successfully complete the video transfer assignment, consideration must be given as to whether students made full use of these resources. In evaluating the above statements, it is important to note that 30 percent of the responses to question 4 indicated that no improvements needed to be made to the video simulation.
Other identified requests for improvement included shorter videos, a mock video to be used as an advance organizer, better sound, and the use of a different room for students to view the video. In terms of shorter videos and the use of a mock video, the authors will consider using a shorter mock video to orient students to the workflow process and the identification of errors.
一个问题,很明显的使用the video simulation in the classroom was sound. Students were broken up into groups, and it was not uncommon to have four different versions of the video simulation running on student laptops at one time. Some groups went out in the hall to work, while another group went to the library. In the future, a bigger room with better acoustics will be needed so that students are not distracted by what other groups are doing. Another alternative would be to provide students with a device that allows them to plug multiple headphones into one laptop.
最后,作者觉得讨论是很重要的ss the theme representing students’ desire for a nonclinical simulation. A major concern of the authors, especially the nurses, is that this type of thinking perpetuates the divide between the administrative and clinical aspects of healthcare. One of the key principles of lean thinking is to eliminate this divide and, more importantly, to get managers out of their offices and onto the shop floor, or, in the example of the video simulation, into the operating room and the NICU. To appropriately use technology and get clinical staff to use new technology, managers must understand how clinicians perform their jobs. A goal of this simulation was to provide students with some level of understanding of how clinicians and nursing staff perform their jobs. A final concern, reflected in several students’ comments, is that the principles of lean thinking are the same in manufacturing and finance as they are in healthcare. The industries may be different, but the techniques used to improve the processes are the same. To provide an example, Virginia Mason Medical Center in Seattle, Washington, was one of the first hospitals to adopt lean thinking.35To understand the lean thinking process, they didn’t send all their senior executives to another healthcare organization, but to a Hitachi air conditioning plant in Japan, to study how that organization implemented lean thinking. For healthcare to move forward, administrators and clinicians must be helped to work together as a team.
When asked whether the video simulation prepared them to perform workflow analysis in the future, 24 percent of the students cited their ability to visualize the transfer process as a positive. Furthermore, an additional 24 percent believed that the video simulation prepared them for future workflow assignments.
最后,视频模拟是成功的因为se it gave students a taste of life in a clinical setting. For many of the students, this was their first opportunity to visualize the actions that take place in a surgical suite and a neonatal intensive care unit. Because the video simulation contained errors and showed clinical staff performing with total disregard for the safety of the patient, it heightened the experience and gave students a sense of the importance that workflow analysis plays in patient care and safety. The results of the formative evaluation suggest that video simulation is a good method for operationalizing Kolb’s theory of learning because it places students in a real-world situation that allows students to visualize a process, reflect on that process, and develop solutions for process improvement.
Overall, the evidence presented suggests that when used appropriately, video simulation of a selected process can help students learn about lean thinking and workflow analysis. Because the evidence is based solely on student opinion, authentic techniques must be developed to assess what students have learned via their exposure to the video simulation and, more importantly, whether students can transfer the skills learned to other healthcare and nonhealthcare processes and services. Currently, assessment is a weak area in the field of medical simulation; one of the goals of the authors will be to develop an assessment tool for students who use the transfer video simulation. Another goal for the design team will be to embed elements of gaming theory into the video simulation to enhance appeal and increase student interaction. Examples include creating a point scoring system for the type and number of errors identified, and assigning roles to students. Students taking on a specific role will examine the role and make suggestions for how that role can be improved. This may alleviate some of the emotional and cognitive overload that students experienced as they began to view the video. It may also help students to focus their attention on one specific feature of the video simulation rather than trying to take in the entire video all at once.
Finally, the authors agree that students should be exposed to both clinical and nonclinical processes and services. This will allow students to transfer their newly acquired skills as well as their critical thinking skills to unfamiliar processes. With this in mind, the authors will begin to develop other video simulations to complement the transfer video simulation.
