Abstract:

【Purpose/significance】 Based on the literature study, the current development status of health informatics is sorted out from

the perspectives of research themes and development evolution to provide reference for related scholars to better engage in health infor⁃

matics research.【Method/process】 Firstly, the health informatics literature was obtained from Web of science, and the literature was

classified into three datasets of medicine, computer, and library intelligence by using JCR and ESI subject classification methods; sec⁃

ondly, the research themes and development and evolution trends of health informatics in the three datasets were analysed by using the

Bertopic model-based theme mining method.【Result/conclusion】 From the point of view of research themes, health informatics

mainly contains six research themes: the application of artificial intelligence in the field of health, health knowledge services, user

health information behaviour, the application of information technology in the clinic, health information storage and management, and

the application of human-computer interaction systems; From the perspective of development trend, it is an inevitable trend for the de⁃

velopment of health informatics to realize multidisciplinary cross-fertilization while retaining the characteristics of each discipline on

its own.【Innovation/limitation】 This paper provides a comparative analysis of the research similarities and differences of health infor⁃

matics in different disciplines, which helps to clarify the origin and developmental evolution of health informatics, and at the same time

provides a basis for the future research innovation and spatial expansion of health informatics. However, this paper only collects the re⁃

search data of health informatics in the three core areas, and the scope of the data collection can be further expanded in the later stage,

so that it can be analyzed in greater depth from a wider range of disciplinary areas.
