Creation and Validation of an Educational Video about the Importance of the Preanesthetic Consultation

Introduction: The pre-anesthetic consultation (PAC) is considered a fundamental step in the perioperative phase, and it is a moment of communication between the anesthesiologist and the patient, where the patient can be informed and clarified, characterizing this a communicative and therapeutic process. However, its benefits are still generally unknown. Educational videos are sur-facing as fast-access media that can reach a wide audience. Some studies have highlighted the benefits of using educational videos about PAC. In this con-text the current study provides an experience report about the process of creation and validation of an educational video about PAC. Methods: In order to choose an educational product, the technical aspect, as well as the cognitive, multisensory stimuli and personality structure of individuals must be observed. This educational video was made based on the CTM3 method consisting of the following stages: Educational product Conception (C); Theoretical framework (T); and Methodological framework (M3), this last one is based on 3 theories: Transactional Analysis, Multisensory Exploration, and Neuro-linguistics. Results and Discussion: The creation and validation of this educational video comprised seven stages. The video length was approximately 2 minutes 24 seconds, and it was projected in 10 scenes. Finally, the video was submitted to a validation process by an ad hoc committee. The advantages of educational resources, particularly vious studies about the use of videos, as well as cognitive and sensory aspects, it is also concluded that this educational video is relevant and has the potential to promote CPA information to its target audience.


Introduction
The pre-anesthetic consultation (CPA) is a fundamental step for the preoperative preparation of the patient (Brazil, 2017), and can be defined as a process that precedes the stage of administration of anesthesia for surgical or diagnostic procedures. The gold standard of the CPA assumes that it takes place in an office, whenever possible before the patient's hospitalization (Mathias, 2016). The general public is unaware of the benefits of CPA. An interesting and effective way of transmitting this information is through health education which, according to Santos, Alves, Warren, & Wyszomirska (2019), is a strategy used through interventions with the objective of facilitating learning, changing habits and bringing benefits to the population object of the intervention. For those who educate, a great challenge is to awaken reasons for learning, with the aim of making topics more interesting, being able to work them through technological resources, so that knowledge can be disseminated more efficiently (Moreira, 2006;Gómez & Pérez, 2013). One of the widely used resources consists of educational products, which are defined as facilitators of learning on any topic (Ruiz, Motta, Bruno, Demonte, & Tufró, 2014), must be easily accessible, available on the internet, through institutional repositories and open access platforms (Nielzer, Fabri, Frasson, & Pilatti, 2015). Among these resources, videos stand out as a means of easy communication and quick access, reaching a wide and varied audience, disseminating information in a playful and attractive way, causing a positive impact on the transmission of information and content, exploring the view and the visualization of people, colors, scenarios, spatial relationships, among other associations (Moran, 2002;Williams, 1988;Coutinho, 2008).
Studies reinforce the importance of educational videos and their impact on the populations studied, especially in the surgical area and in anesthesiology.
Another important step is the process of validating a product, as to this process it is attributed the veracity that what was proposed and attested by those who evaluated declares the material's capacity to produce what was proposed; confirms that the content and form of technical production work according to its objective (Ruiz et al., 2014). The validation of educational products is recommended by Fondo de las Naciones Unidas para la Infancia (UNICEF, 2003) and CAPES in their teaching document (Brazil, 2019 (Ziemendorff & Krause, 2003). According to Leite (2018), it is important to validate these products, through reflections on issues relevant to each specific format. Lastly, Latini, Oliveira, Anjos, & Carvalho (2011) emphasize the relevance of creating categories for the analysis of educational products and reiterate the need to verify their contribution to the improvement of teaching practice, promoting the articulation between theory and practice and social insertion. Oliveira, Santos, & Santos (2002: p. 127), evaluating the effectiveness of three educational games focused on oral hygiene, concluded that "There was an effectiveness in the application of educational games as a means to help change oral hygiene habits in children".
This experience report refers to the process of building and validating an educational video, the main purpose of which is to alert, clarify and guide the interested public on the importance and advantages of CPA, based on the current legislation on the anesthetic act, in addition to the scientific literature (Brazil, 2017). This theme was chosen due to the evidence that shows the importance of pre-anesthetic consultation (for better clarification and reduction of the anxiety level of surgical patients) as well as the relevance of educational videos for this purpose.

Methods
The experience report is a tool that presents a reflection on an action or a set of actions that address a situation experienced in the professional sphere of interest to the scientific community.

Conception and Construction of the Educational Product
The conception of the product is the initial moment, where the theme, the type and what elements will compose this product are established. It is the moment of creativity, it is when we ask ourselves what resource we will produce-A video, a board game, a booklet, an e-book or blog? Online or printed?-In order to answer these questions, it is necessary to know the target audience and the characteristics of such audience, therefore, this prior knowledge is fundamental for good planning.

Theoretical Framework
The theoretical framework is located in the main electronic databases: Latin

Methodological Framework
The methodological framework embodies the method used in making the product and was based on the three theories, namely: Transactional analysis with the insertion of elements with the potential to evoke in the individuals the three states of Ego (Father, Adult and Child). Multi-sensoriality, with the insertion of elements that can awaken the five senses (sight, smell, taste, hearing and synesthetic) in the target audience and the neurolinguistic programming inserting anchors, defined here as anything that gives access to an emotional state, or to a memory (O'Connor & Seymour, 1995). It is worth mentioning that all planning of the methodological framework focused on the insertion of all the elements mentioned above, exploring the target audience with the three states of ego, the five senses and the anchors, this is due to the difficulty in accurately identifying which of these elements will be available to each individual the moment he has access to the product, therefore, it is essential that the approach through the elements is multiple and assertive.

Product Validation
For this work, technical validation was used, following a script: 1) Publication of public notice for product registration; 2) Three to five ad hoc evaluators are invited to the validation session, with-at least-a master's degree or preferably doctors in the area of Communication, Education and Health, with an emphasis on evaluators with expertise in Education and Communication.

Results and Discussion
This work consists of an experience report of the construction and validation of an educational video whose main purpose is to alert, clarify and guide the general public about the importance and advantages of CPA. According to Santos,  (Cakmak et al., 2018). A third study, conducted in Taiwan, also with the objective of investigating the effects of a video with anesthetic information, found that there was a significant reduction in anxiety levels and increased satisfaction in the group that watched the video, compared to the group that received guidance statements about anesthesia (Lin et al., 2016). These studies reinforce the importance of educational videos when analyzing their impact on the studied populations, but they do not report on what the process of making these videos was based, or on what theoretical framework they were based upon.

Construction of the Video
A communication/educational material must combine knowledge and technology, in order to disseminate/transmit knowledge, exchange of information and training to the target audience. Each type of material has its specificities and potentials and must be carefully worked on, as the target audience, based on the information provided, can acquire knowledge and use this information, replicating them.
The video was conceived from discussion meetings of the authors of the work, as well as from the discussion of the topic with some colleagues who are anesthesiologists and finally reading articles on the use of educational videos for the public According to Moran (2002), videos are easy to communicate and have quick access, reaching a wide and varied audience. As compared with Muller (2016), this resource can explore multi-sensoriality, converting it into information that reaches the processing center-brain-in the form of sensory stimuli. Next, a script was elaborated, based on the most relevant information about CPA, observing the care with a simple and clear language, aiming to transmit the content to the target audience, literate or not. The script consisted of topics, with the elaboration of short phrases, narrated in the active voice. The visual resources were chosen based on keywords that best synthesized the topics. According to Fiorentini & Carneiro (2002), the script must be written in a language that expresses not only speech, but also images and body expressions. The next step was the organization of the scenes, respecting each topic and adding the appropriate audiovisual resources for each shot. Care was taken to harmonize the images and sounds with the information transmitted in each scene. Finally, elements that address the individual's cognitive aspects were inserted, for greater effectiveness in communication and aiming at access to a greater number of individuals (Santos et al., 2019).
The images used in the video are in the public domain, the voice belongs to the main author and for this reason, an authorization term for the dissemination of the narrated sounds was signed. The video has an approximate duration of 2 minutes and 24 seconds consisting of 10 scenes: 1) First scene: presentation about the CPA, drawing public attention to its importance. This way it evokes the Adult ego State in which there is objective reasoning, the analysis of reality. The scene also works with visual and sound stimuli.
2) Second scene: the objective is to emphasize the fact that CPA is usually the patient's first contact with the anesthesiologist. In this scene there is the evocation of the Parent ego state which has the purpose of educating, protecting. When conveying a sense of embracement, it also evokes the Child ego state. Finally, it also works with visual and sound stimuli. There was an anchor inserted in all scenes as the image of a stethoscope and clipboard in order to reinforce the message. Several studies report that surgical patients very often have preoperative anxiety, probably started at the time of surgery planning (Krupat, Fancey, & Cleary, 2000;Macario, Weinger, Truong, & Lee, 1999). Other studies conclude that there is also an increase in the degree of satisfaction and understanding of patients, in addition to a reduction in anxiety, when they are informed through educational videos in comparison to the transmission of information only verbal or written (Done & Lee, 1998;Bondy, Sims, Schroeder, Offord, & Narr, 1999;Lee, Chui, & Gin, 2003;Lemos, Lemos-Netoa, Barrucand, Verçosa, & Tibirica, 2019).
The information transmitted through videos brings up attention and memorization, hence the reason this resource has been increasingly utilized as informational support in the health area, especially in intervention actions, thus having great pedagogical power (Moraes, 2008). Still according to Moraes (2008), videos have the power to intervene, being able to participate in disease prevention and health promotion actions by changing people's behaviors. Videos still play a very relevant role in the teaching process, even after the emergence of new technological and media resources, such as social media and the internet. According to Moran (2002), video can also bring knowledge through the senses, through what is seen and felt, in addition to sound effects, which help in fixing the information contained in the videos themselves.

Video Validation
After editing, the video was entered in the Educational Products Validation Ses-

Conclusion
The use of the CTM3 Method was essential for the elaboration of the video, as its methodology considers, particularly, the cognitive and sensory aspects, as well as the specificities of each individual. Some difficulties were encountered in the making of this video including how to explore all the senses and how to adapt them maintaining the original requirement which was to make it interesting and didactic, however, without distancing itself from the initial concept of simplicity in an educational video. The insertion of anchors and working with the ego states in the scenes also requires skill, something that is greatly facilitated with the use of the above-mentioned method. It is a process which requires planning, furthermore it is important to highlight that the video may not be lengthy in order not to cause disinterest to the audience.
Finally, after reporting its construction and validation steps, in addition to reporting previous experiences on the use of video in anesthesiology, we can conclude that the video has enormous potential to reach its target audience, bringing numerous benefits, among them, the reduction of the target audience's anxiety, improved communication and empathy between doctors anesthesiologist and his or her patient. In addition, it can also be used as a tool for the permanent education of health teams, causing an indirect impact on better management and preparation of the preoperative period, contributing to reduce hospital and health care costs by reducing the rate suspension of surgeries, as well as reducing the request for unnecessary preoperative exams.
The video is freely reproducible, being an open educational resource, which can be made available on platforms and media, for the general population, health teams, as well as being shown in the waiting rooms of the offices and clinics.
