BACKGROUND: As the second-largest economy in the world, China has invested considerable financial and policy support into hospital informatization since health care reform in 2010. However, the results and experience of such investments have not been compared with relevant research and applications in the United States and Europe. OBJECTIVES: From the perspective of professional conference proceedings, we comparatively analyzed the current situations, characteristics, hotspots, and trends of medical informatics (MI) development in China, the United States and Europe to help Chinese MI researchers and practitioners summarize their experiences and determine gaps compared to their American and European peers. We also aimed to educate foreign peers about the special contributions of the China MI circle and facilitate multilevel international cooperation. METHODS: English conference proceedings of the American Medical Informatics Association (AMIA) Annual Symposium (USA), Medical Informatics Europe (MIE, Europe) and World Conference on Medical Informatics (MEDINFO, Global) from 2007 to 2017 were searched within Scopus and Pubmed. Proceedings of Chinese MI conferences (CMIAAS, CHINC, CHITEC, CPMI) (China) were searched within Chinese databases CQVIP, CNKI and WanFang during the same period. The datasets were preprocessed via a Natural Language Processing (NLP) package on Python and were qualitatively and quantitatively analyzed via bibliometric methods. RESULTS: Overall, 2285, 1601, 1930 and 5431 papers were publicized from the AMIA Symposium (USA), MIE (Europe), MEDINFO (Global) and Chinese MI conferences (China) between 2007 and 2017, respectively, with an H-index of 32, 19, 19 and 3, respectively. The AMIA Symposium, MIE and MEDINFO received submissions from 43, 68 and 80 countries (or regions), respectively, but Chinese MI conferences (CMIAAS, CHINC, CHITEC, CPMI) only received submissions from 3 foreign countries. Author affiliations were quite similar among the AMIA Symposium, MIE and MEDINFO, as 67%, 75% and 70% of authors came from universities/colleges, respectively; 18%, 10% and 11% came from medical institutions, respectively; and 7%, 8% and 10% came from institutes, respectively. In contrast, the majority (54%) of authors in Chinese MI conferences came from medical institutions followed by universities/colleges (17%) and institutes (10%). Of the top 5 authors with the most publications in AMIA Symposium, MIE and MEDINFO, 14/15 of them had medical backgrounds, but only one author from the Chinese MI conferences majored in medicine. Electronic medical records (EMR) were included in the top 10 high-frequency keywords by all four conference groups, but the amount of time that this keyword appeared differed in 2009, 2011, 2012 and 2013, respectively. CONCLUSIONS: The MI annual conferences are all different among China, the United States and Europe. China lags in the theoretical and discipline bases but has made considerable investments in the past 10 years. China should fully use its second-mover advantage and application advantages and utilize international experiences and cooperation to make stronger contributions to global MI development.
背景：作为世界第二大经济体，自 2010 年医疗改革以来，中国在医院信息化方面投入了大量的财力和政策支持。然而，这些投资的结果和经验尚未与美国和欧洲的相关研究和应用进行比较。
目的：从专业会议论文集的角度，我们比较分析了中美欧医学信息学（MI）发展的现状、特点、热点和趋势，帮助中国 MI 研究人员和从业者总结经验，确定与美欧同行相比的差距。我们还旨在向外国同行介绍中国 MI 界的特殊贡献，并促进多层次的国际合作。
方法：在 Scopus 和 Pubmed 中搜索了 2007 年至 2017 年期间美国医学信息学协会（AMIA）年会（美国）、欧洲医学信息学（MIE，欧洲）和世界医学信息学大会（MEDINFO，全球）的英文会议论文集，以及同期在中国数据库 CQVIP、CNKI 和万方中搜索了中国 MI 会议（CMIAAS、CHINC、CHITEC、CPMI）（中国）的论文集。通过 Python 上的自然语言处理（NLP）包对数据集进行预处理，并通过文献计量学方法进行定性和定量分析。
结果：总体而言，2007 年至 2017 年间，AMIA 研讨会（美国）、MIE（欧洲）、MEDINFO（全球）和中国 MI 会议（中国）分别发表了 2285、1601、1930 和 5431 篇论文，H 指数分别为 32、19、19 和 3。AMIA 研讨会、MIE 和 MEDINFO 收到了来自 43、68 和 80 个国家（或地区）的投稿，而中国 MI 会议（CMIAAS、CHINC、CHITEC、CPMI）只收到了来自 3 个外国的投稿。AMIA 研讨会、MIE 和 MEDINFO 的作者机构非常相似，分别有 67%、75%和 70%的作者来自大学/学院；分别有 18%、10%和 11%的作者来自医疗机构；分别有 7%、8%和 10%的作者来自研究所。相比之下，中国 MI 会议的作者中，54%来自医疗机构，其次是大学/学院（17%）和研究所（10%）。在 AMIA 研讨会、MIE 和 MEDINFO 中发表论文最多的前 5 名作者中，有 14/15 人有医学背景，而只有一名来自中国 MI 会议的作者主修医学。电子病历（EMR）是四个会议组中都包含的前 10 个高频关键词，但这个关键词在 2009、2011、2012 和 2013 年出现的时间不同。
结论：中美欧的 MI 年会各不相同。中国在理论和学科基础方面落后，但在过去 10 年中投入了大量资金。中国应充分利用后发优势和应用优势，利用国际经验和合作，为全球 MI 发展做出更大贡献。
