Abstract: Objective To pay attention to the status of mental health research of medical personnel at home and abroad,provide basis and direction for improving the mental health problems of medical staff. Methods Based on CiteSpace software,the academic journals from the China National Knowledge Infrastructure（CNKI） and Web of Science（WOS） core collection databases were used as data sources,with themes such as "mental health" and "medical personnel" being used for retrieval,the search time range was from 2019 to 2023（as of January 20,2023）,and the visual analysis was performed on the obtained literature keywords and highlight words. Results Totally 357 CNKI articles and 4 655 articles in the WOS core collection were included in.The number of relevant research documents showed a fluctuating trend of rising first and then decreasing,the number of relevant documents at home and abroad grew rapidly in the early stage of this period and peaked in 2020 and 2021 respectively,subsequently,the growth rate decreased. The domestic research focus was the influencing factors of mental health problems of medical staff and focuses on social support,while the foreign research focus is the satisfaction of mental health and psychological care needs of medical staff.The domestic and foreign studies have focused on mental health issues of medical staff. Conclusions The foreign researchers pay more attention to the mental health problems of medical workers than those in China. The research hotspots in relevant fields at home and abroad have both common points and differences. The researchers in relevant fields should communicate together in the research process to provide more scientific theoretical references for improving the mental health problems of medical personnel,so as to promote the development of the service system in this field.
