HIT score for 213,215 medical informatics publications during 2010-2020

We use three MeSH branches as representations of Health-demand, Informatics-supply, and Technological applications (hereafter, H-I-T model) and use their co-occurrences to measure the digital medical innovation process in China. The detailed definition of HIT is as follows：1)      H: The entire “Diseases [C]” branch as well as two subbranches, i.e., “Health [N01.400]” and “Public Health [N06.850]” are regarded as a representation of health demand for HIT innovations. “Health [N01.400]” and “Public Health [N06.850]” are under the branches “Population Characteristics [N01]” and “Environmental and Public Health [N06]”, respectively—with the top root “Health Care [N]”. So, we use two MeSH terms “health” and “public health” to represent the population health demand, and the "diseases category" MeSH terms to indicate the individual health demand (specific diseases management).2)      I: The “Information Science [L]” branch as a representation of the supply side in terms of informatics concepts and techniques.3)      T: The “Analytic, Diagnostic, and Therapeutic Techniques and Equipment [E]” branch is a representation of the state of the art of technological applications, namely the functions to be realized by informatics, e.g., diagnosis, therapeutics, surgical procedures, investigative techniques, equipment and supplies.In the H-I-T model, every related article can be classified as Health demand (H), Informatics-supply (I), Technological applications (T), or a combination of these three using its MeSH terms and HIT score. MeSH terms are arranged in an alphabetical and hierarchical structure from the most general level to the narrowest level. Table 1 shows the branches of MeSH terms used in distinguishing the H-I-T classification. Note that since the MeSH term “Public Health” has another tree number H02.403.720 (Branch of medicine concerned with the prevention and control of disease and disability, and the promotion of physical and mental health of the population on the international, national, state, or municipal level), terms under this branch are also included in health-demand (H) category. These terms include Epidemiology, Molecular Epidemiology, Pharmacoepidemiology, Preventive Medicine, Environmental Medicine, Occupational Medicine, Preventive Psychiatry.To calculate the HIT score, the MeSH list and the MeSH terms contained in each article are required:The MeSH 2020 stored in file: MeSH_trees.csvThe UK/US/CHINA/WORLD's medical informatics publications and HIT scores stored in files: redo_cn_HIT_pall.csv redo_UK_HIT_pall.csv redo_UK_HIT_pall.csv redo_WORLD_HIT_pall.csvAll files contain publication id(pubid),publish year(year),mesh terms(mesh),H score(H),I score(I),T score(T)

本研究采纳了健康需求、信息学供给与技术应用（以下简称H-I-T模型）三个MeSH分支作为表征，并利用其共现情况以衡量中国数字医疗创新过程。H-I-T模型的详细定义如下：1）H：将“疾病 [C]”整个分支及其两个子分支，即“健康 [N01.400]”和“公共卫生 [N06.850]”视为H-I-T创新的健康需求表征。其中，“健康 [N01.400]”位于“人口特征 [N01]”分支下，“公共卫生 [N06.850]”位于“环境和公共卫生 [N06]”分支下，两者均隶属于顶级根节点“医疗保健 [N]”。因此，我们采用“健康”和“公共卫生”两个MeSH术语来代表人口健康需求，而以“疾病类别”MeSH术语来指明个体健康需求（特定疾病管理）。2）I：“信息科学 [L]”分支作为信息学概念与技术供给侧的表征。3）T：“分析、诊断和治疗方法及设备 [E]”分支代表技术应用的尖端状态，即信息学所能实现的功能，例如诊断、治疗、手术程序、调查技术、设备和用品。在H-I-T模型中，每篇相关文章均可根据其MeSH术语和H-I-T评分被分类为健康需求（H）、信息学供给（I）、技术应用（T）或这三种类型的组合。MeSH术语按照从最一般到最具体的级别排列，形成字母和层级结构。表1展示了用于区分H-I-T分类的MeSH术语分支。请注意，由于MeSH术语“公共卫生”具有另一个树号H02.403.720（涉及疾病预防和控制、以及在国际、国家、州或市级层面促进人群身体和心理健康），因此该分支下的术语也被纳入健康需求（H）类别。这些术语包括流行病学、分子流行病学、药理学流行病学、预防医学、环境医学、职业医学、预防精神病学。计算H-I-T评分时，需要MeSH列表和每篇文章中包含的MeSH术语：存储于文件“MeSH_trees.csv”中的MeSH 2020；存储于文件“redo_cn_HIT_pall.csv”、“redo_UK_HIT_pall.csv”、“redo_WORLD_HIT_pall.csv”中的英国/美国/中国/世界医疗信息学出版物和H-I-T评分。所有文件包含出版物标识（pubid）、出版年份（year）、MeSH术语（mesh）、H评分（H）、I评分（I）、T评分（T）。
