“…On the other hand, some studies use bibliometric methods to describe health informatics research through quantitative research methods such as statistical analysis (Binkheder et al , 2021; Han et al , 2022; Liu et al , 2019), social network analysis (Saheb and Saheb, 2019) and scientific knowledge mapping (Zou and Sun, 2020; Kokol et al , 2018; He et al , 2022; Liang, 2010). These studies point out that health informatics research focused on topics such as the application of computer science in health care, the impact of health informatics on patient safety and quality of care, implementation and evaluation of electronic health records and decision support systems (Saheb and Saheb, 2019; He et al , 2022), and future research trends may be patient-generated health data, deep learning algorithms, quantitative self and self-tracking tools and IoT-based decision support systems (Liu et al , 2019), and how to meet user needs and improve the usability of health tools is also a potential research hotspot (Han et al , 2022). Besides, there are also studies that have made efforts to reveal the current state of research in related areas or subfields of health informatics, such as in the areas of COVID-19 (Chen et al , 2021) and big data research in health informatics (Gu et al , 2017).…”
