Objective To analyze the quantity,quality,and research layout of medical scientific papers(in Chinese)published by various regions,hospitals,and institutions in Inner Mongolia Autonomous Region from 2018 to 2022,in order to understand the overall scientific and technological level of our region,providing an overview of support for medical scientific research in the entire region and provi-ding references for the rational layout of medical scientific and technological development.Methods From July to August 2023,Chinese National Knowledge Infrastructure(CNKI)was used as the data source to systematically retrieve Chinese medical literature related to Inner Mongolia Autonomous Region from 2018 to 2022.Bibliometric methods were applied to analyze the quantity and quality of literature,as well as regional and institutional distribution.Results From 2018 to 2022,there were 5 273 articles published in core journals in Inner Mongo-lia,accounting for 30.96%of the total.Among them,1095 articles(20.77%)were indexed in CSCD,1 567 articles(29.72%)in Peking University Core Journals,and5164 articles(97.93%)in Science and Technology Core Journals.The journal with the highest publication volume among the top10 core journals was"Journal of Inner Mongolia Medical University,"accounting for20.77%.The top three regions in terms of total output of core journal articles were Hohhot,Baotou,and Chifeng,while Xing'an League and Alxa League had very few pub-lications.Among different levels of hospitals,tertiary hospitals had much higher publication volumes than primary and secondary hospitals.Among different types of institutions,medical institutions had higher publication volumes than higher education institutions.The top three in-stitutions in terms of publication volumes in core journals were Affiliated Hospital of Inner Mongolia Medical University,Inner Mongolia Med-ical University,and Inner Mongolia People's Hospital.Conclusion The number of core journals in Inner Mongolia needs to be increased,and the quantity of research output varies among regions.It is necessary to strengthen scientific research management systems,improve the level of research achievements,and promote scientific and technological innovation in Inner Mongolia.
