As people's health needs and expectations grow, so does the awareness of the weaknesses in medical humanistic care and other emergent problems. Patients want humanized medical care. The humanistic literacy of medical students studied has attracted considerable attention. The research is valuable in three ways. Firstly, it summarizes the development status and ideological basis of humanistic literacy among Chinese medical students while analyzing important research questions; secondly, it provides an important reference for researchers to obtain a correct understanding of humanistic literacy research among Chinese medical students; thirdly, it helps researchers to grasp the scientific development and research questions in the field of humanistic literacy among Chinese medical students.
In terms of the temporal distribution of publications, increasing attention has been directed toward the humanistic literacy of Chinese medical students' research over time from 1995 to 2022 in China. Research on the humanistic quality of medical students stabilized after a period of rapid growth in the last 15 years. Currently, this topic is academically popular. Related theories and analytical methods are being gradually developed. From 1995 to 2022, China paid much attention to research on the humanistic quality of medical students in terms of the time distribution of publications. The first article by Huazhong University of Science and Technology was “On Improving Students' Humanistic Quality and Chinese Language Level.” It was published in 1995 in Higher Engineering Education Research. This was the first time the question of students' humanistic quality had ever been raised. In the following five years, the issue of humanistic quality was encouraged and spoken about. In 2001, an article titled “Strengthening Humanistic Education in Medical Education” opened doors to humanistic quality education for medical students. In 2022, the number of related articles on medical students' humanistic qualities increased. The humanistic literacy of medical students is also included in the expert consensus on humanistic education in dentistry, which requires that the new era of medicine requires students to have medical humanistic literacy (30). Some studies have shown that offering humanities classes in medical schools can develop humanistic literacy in medical students(6). By developing the humanistic qualities of doctors, we can effectively improve the doctor-patient relationship(19, 31). This study found that medical experts and educational scholars have been the main force driving research on humanistic quality among Chinese medical students. This is consistent with some international studies in which some international medical educators have called for modern medical education to be oriented toward humanistic literacy education(32). This study aimed to search the published literature using CiteSpace analysis to provide personalized ideas to guide future research in the field.
Scientific cooperation is a process in which two or more authors share their resources and talents and create studies together(33, 34). A good cooperative relationship among scholars can establish an academic network aimed at sharing innovative ideas and concepts, generating new knowledge, ultimately reducing the waste of academic resources, and improving research productivity(35). This study found that the density of the author collaboration graph was 0.0022, indicating that only 0.22% of the potential relationships in the medical student humanistic literacy research network were realized. This is similar to studies in other medical fields, where scientific collaboration is rare and needs to be strengthened(36). Furthermore, this indicates that a strong partnership has not been formed among authors in medical students' humanistic quality. The density of the cooperative agency atlas was 0.0017, implying that only 0.17% of the potential relationships among medical students' humanistic literacy research institutions have been realized. This further shows that cooperation between institutions and scholars is weak. Strong partnerships have not been established yet. Because cooperative studies in this field are few, the centrality of scholars and institutions is not obvious. Researchers and institutions mostly study alone in the present situation. They have not yet formed a cooperative system. There are relevant studies that show that strengthening collaborative behaviour, especially between different institutions or countries/regions, will promote the progress and internationalization of research(37). Researchers need to focus on representative collaborations of scholars and institutions that can help us advance our research.
To identify important research topics in the humanistic quality of Chinese medical students' research, the study conducted a keyword co-occurrence analysis. Co-occurring keywords reflect research hotspots in the field (38, 39). In terms of research hotspots, scholars have shown great interest in humanistic quality and literacy and medical students. Additionally, the accomplishments of higher vocational and higher vocational college students have been widely discussed. Research on the humanistic quality of Chinese medical students has become more diversified and detailed. Medical colleges lead the study on medical students' humanistic quality in China. They determine the direction and focus of such a study. Through visual analysis of the research literature on this topic, this study provides scholars committed to this field with research characteristics and hotspots evolution trends. Moreover, it provides direction, guidance, and information on the practical methodology for subsequent research into issues related to the medical education system.
The Health China strategy has put forward new requirements for medical education. Medical education in the context of the new medical model needs to effectively deal with complex humanistic elements. During the implementation of the new medical strategy, the scope of medical risks has expanded and the awareness of patients' rights has increased, humanistic literacy should be integrated into medical education to help doctors develop appropriate literacy and competence. Humanistic literacy education is an alternative path to try to solve complex problems through medicine and humanities in compliance with the change of medical education approach. By cultivating the humanistic literacy of medical students, we can achieve improvement in the doctor-patient relationship, reshape the medical humanistic environment, and improve the quality and level of new medical education.
Research limitations
To our knowledge, our study is the first bibliometric analysis of publications related to humanistic literacy among medical students. Nevertheless, this study has some limitations. First, there may be language bias because although we did not set any restrictions on the language of the publications in our study, most CNKI publications were in Chinese. Second, the quality of CNKI publications varies. We lacked a quality assessment of publications, and our analysis may have given equal attention to publications of different quality. Finally, the data currently used for the analysis were extracted only from CNKI and did not include data from other search engines such as Scopus (Elsevier), PubMed, or Google Scholar (Google LLC). Therefore, it is possible to miss publications that appear only through one of these other search engines. We plan to address this issue by exploring ways to combine different data sources in future work.
