According to the results of the present study, interpreting paintings by the VTS method improves the capability to communicate effectively. It also improves visual and auditory sensitivity, accuracy and attention, interaction and collaboration with others, teamwork, and an understanding of their contribution to the group. In addition, from the students’ perspective, contemporary Persian painting plays a prominent role in reducing job exhaustion, anxiety, and stress, and contemporary miniature affects students’ emotions by applying the topics and issues of the day, and paying attention to cultural and social issues creates a sense of calm and aesthetics in students. Classical painting conveyed a sense of calm and discomfort to the students, which according to the students’ interpretive content analysis, the reason is due to the profound effect of this painting on the meaning transmission so that it exposed the comprehensive views on the subject to the viewer’s sight. Given that the Safavid era miniature contains various signs expressing the details of the social context and cultural traditions related to human beings, it conveys various feelings. On the other hand, the application of classical painting and contemporary Persian painting in VTS discussions in medical education is more prominent than in the Safavid era miniature.
Acquiring professional medical qualifications is essential to providing effective healthcare services based on the community’s needs. In addition, we are now in a period of medicine in which the demands on physicians are increasing day by day since the puzzles of our era, such as unknown pathogens, emerging biological threats, and environmental disasters, as well as new technologies and rapidly changing scientific discoveries, broaden the medical landscape. Currently, the emphasis is on the capability-based curriculum instead of the subject-central curriculum, which is in semester form (
16), and multi-dimensional assessment of professional capability (such as teamwork ability, clinical reasoning, etc.) replaces knowledge-based assessment (
17), so that graduates have sufficient skills in addition to strong knowledge. Therefore, special attention is paid to teaching soft skills such as communication, especially with patients, commitment, and professional ethics. In this regard, the acquisition of non-medical knowledge-based abilities constitutes a major part of a competent physician’s performance, as shown in
Table 1. Educating these capabilities can benefit from accurate observation, accurate recording, and an interdisciplinary approach to knowledge. This approach is somehow art in science. Harmony of art and science means that art is guided by science, and science is expressed through art (
11). In this regard, three issues are raised: (1) “arts as therapy”; (2) “community arts and health”; and (3) the use of art in teaching medical students. The term “medical humanities”, in a limited sense, is used to refer to the latter, i.e., art and medical education, and the first two cases can be placed in “art and health” (
18). The humanities, including the arts and social sciences, are important aspects of daily medical activities and support the development of interpersonal skills required to play leadership and management roles in a multidisciplinary team. Healthcare management guided by the physician has been shown to lead to better financial and clinical performance (
19). The duty of physicians is not only to treat the disease but also to relieve and ensure the comfort of the patients. It reflects the human spirit of medicine. If this human dimension is separated from medicine, the greatest betrayal of medicine will take place. Achieving human medicine requires a paradigm shift from what can be called medical reductionism to medical holism, in which patients are not reduced to disease and the body but are seen as complete individuals in fields and relationships (
20). The arts can contribute to the perception of the whole person in at least three ways: (1) shared human experiences; (2) insights into the difference or uniqueness of each person; and (3) enrichment of the individual’s language and thought (
21). In this regard, in examining the relationship between art and medicine, in addition to paying attention to the value of the arts in increasing the understanding of individual characteristics, i.e., “whole person understanding”, what one shares with other human beings is also considered; namely, the holistic view is complemented by a holistic approach to man. Thus, art is complementary to the biomedical perspective. Thereby, in addition to focusing on the disease symptoms, it also pays close attention to the whole person (
22). Given that the “community has a lot of trust in physicians’ knowledge but much less trust in physicians’ clinical behavior”, the inclusion of medical humanities as part of a healthcare professional’s initial training in helping to shape his/her future, both as a compassionate physician and as a thoughtful human being, is vital (
23).
The results of the present study showed that miniature, similar to classical painting, was able to cause effective evidence-based discussions in VTS sessions. Searching in scientific databases did not yield any results regarding the use of miniature in VTS discussions; however, in relation to the classical paintings in supporting the results of the present study, Joel reported that VTS improved the ability to effective communication and teamwork, reduced job exhaustion, and increased job satisfaction. The “interpretive challenge” was improved with the use of VTS. In addition, it remarkably improved the power of observation, which is the central feature of physical examination (
13). Also, several cross-sectional, descriptive-analytical, qualitative, systematic, and trial studies have confirmed the useful effect of VTS in teaching thinking and required communication skills in students of different medical sciences, such as medicine, pharmacy, and nursing. For example, VTS increased the observational skills in medical students to the extent that the evaluation of the effectiveness of VTS implementation in the educational curricula of first-year medical students with pretest-posttest evaluation led to improving visual literacy in the interpretation of radiographic images, so that VTS training increased the total number of words used to describe clinical images, the time spent analyzing images, and the number of related clinical observations (
24). Also, in the second-year medical students, the implementation of the VTS course led to improving learners’ observational skills (
25). A previous study also showed that VTS allowed nursing instructors to use the art to listen carefully, consider the opinions of others, provide details to communicate ideas and observations, and that VTS was the potential to enhance communication and observational skills for inter-professional learning and mutual respect (
26). The content analysis of the topics of a VTS session for nursing students showed that VTS developed observational, cognitive, interpersonal, and intrapersonal skills (
27). A qualitative study also showed that nursing thinking and assessment skills were improved through the use of VTS (
28). A systematic study showed that VTS can help nursing graduate students develop observation, communication, and ambiguity tolerance skills, as well as an improved sense of security in learning and collaborative work (
29). A cross-sectional study on pharmacy students showed that VTS led to the development of personal communication, cultural competence, and critical thinking skills (
30). A field trial study also confirmed that VTS leads to improving visual literacy skills, reducing stress, and promoting active listening and teamwork among medical students (
31).
VTS is a type of art integration in curricula, but not with the aim of “art for art’s sake”, rather clearly contributes to students’ creative thinking and their measurable academic achievement (
12). VTS is focused on art, in which all students participate in a critical thinking process regarding complex artistic elements. It uses visual literacy to teach thinking and communication skills. Research has shown that VTS develops critical thinking skills (observation, evidence-based inference, hypothesizing, correcting, and reviewing) and leads to eloquence. VTS has been established and researched for 30 years and tested in various fields for 12 years. Increased visual sensitivity also leads to accurate interpretation of the patient’s language and behavior, enhances curiosity and imagination in relation to the patient’s experience, improves emotional communication with the patient, and makes the whole-person attitude tangible (
32). The use of VTS to teach the humanities to medical students can increase empathy, understanding, and medical art sensitivity. Visual sensitivity increases team building and collaboration among medical students (
15). Not surprisingly, such curriculum developments are the best tool for preparing learners’ academic achievement. At the same time, students’ knowledge of medical humanities is still low in Iran, and there is no official university program in this regard (
33). From the perspective of students (
30) and education professionals (
14), various studies have emphasized the need to integrate art into the medical science curriculum and also using the art-based teaching-learning method in medical science disciplines, but in a way that no more educational burden is imposed on students.
In the present study, the results of a survey of students showed that contemporary miniature had the greatest impact on reducing job exhaustion compared to the other two paintings. The analysis of students’ opinions suggested that artistic attention to the current status of the community might be involved in this finding. Perhaps part of this issue is due to the colors used in miniature because previous research showed that pink, and blue, with a greater effect, significantly reduce stress. Given that attending clinical duty is a stressful experience among students, students’ stress levels decreased after exposure to pink color therapy and blue, with a greater effect (
34). The goal of implementing VTS-based interdisciplinary programs at Harvard Medical School is also to acquire human capabilities along with the prevention of job exhaustion, which impairs job satisfaction (
13). Given that teaching observational skills, improving psychosocial abilities, and reducing stress are essential to teach professional and flexible healthcare workers in the future, VTS discussion sessions of the contemporary miniature are expected to play an important role in reducing job exhaustion and anxiety.
Despite increasing visual and auditory sensitivity and communication, the miniature has not been able to have a significant beneficial effect in transmitting medical humanities concepts, such as empathy, compassion, respect, and critical thinking, to students. One of the features of the miniature is that it depicts not only a literary text but also the atmosphere of that situation in an imaginative way, i.e., the depicted scenes deal with something beyond that scene and with another world at the same time of everyday life so that the whole painting assumes a mystical, imaginary, and other world nature. It also deals with the fact that the whole painting finds a cryptic, imaginary, and other universal nature (
35), and the more abstract it becomes, the broader and more general concept it depicts. Therefore, the type of painting and perhaps its more abstract form than classical painting seem to have provoked this reaction in students.
The limitation of this study is the absence of a control group and also the small number of participants. Also, it was not possible to include other medical students in the study due to virtual education. It is suggested that for final approval and by using it in educational planning, this study be implemented with larger sample size and in different university centers with different miniatures. It is evident that its proper implementation requires a close interdisciplinary interaction between art and medical sciences, so that both producing artworks with the ability to think and discuss based on the above evidence and as a facilitator can be helpful in discussion sessions.
5.1. Conclusions
Overall, the findings of this study showed that VTS is a unique educational strategy with the potential to help medical students develop a wide range of skills. The use of miniature in VTS topics can be an effective educational and learning tool to increase professional skills and reduce job exhaustion and anxiety; also, it has the potential to meet the challenge of professional development in them. The data indicated that the inclusion of multiple VTS sessions is a valuable addition to the health curriculum that can provide emotional learning experiences to be able to develop and transfer key skills and attitudes related to inclusive care delivery. Nonetheless, these miniatures were not successful in teaching human concepts and critical thinking. It is suggested that various studies be repeated on a larger scale to complete and confirm the results of this study.
