Objective: To explore the utilization of cancer-related data from basic medical insurance databases in China, and promote the application of medical insurance data in cancer prevention and treatment. Methods: Database PubMed, Web of Science, Wanfang, and CNKI were used to select related research papers using data from basic medical insurance system in China published by December 2021. Descriptive analysis was conducted in terms of the number of publications, types of cancer, primary research contents and author affiliations. Results: A total of 65 papers were included in the study. The number of publications increased rapidly after 2016. The most studied cancer type was lung cancer, and healthcare costs were the most common research contents. Fujian, Beijing, and Anhui have made a better use of cancer-related medical insurance databases compared to other provincial regions. The accessibility of the New Rural Cooperative Medical Scheme data was limited due to the high regional barriers, while the accessibility of the urban basic medical insurance data was relatively high. The researchers from Peking University and Fudan University had higher utilization of basic medical insurance data compared with those from other institutions. Conclusions: The utilization of cancer-related data from basic medical insurance databases in China is limited because of poor accessibility, insufficient data sharing, and regional restrictions. Thus, it is urgent to improve data accessibility and promote the integration and utilization of regional medical insurance data.
目的： 掌握中国研究人员利用基本医疗保险数据发表的肿瘤防治领域期刊论文的现状及分布特征，为今后在肿瘤防治中充分、规范和有效地挖掘及使用医疗保险数据库提供依据。 方法： 检索PubMed、Web of Science、万方数据知识服务平台、中国知网4个数据库建库至2021年利用中国基本医疗保险数据发表的论文，从发文数量、肿瘤类别、主要研究内容和作者机构等维度进行描述性分析。 结果： 共纳入65篇文献。2016年后，发文量快速增长。研究数量最多的肿瘤是肺癌，最高频的研究内容是肿瘤医疗费用。福建省、北京市、安徽省的基本医疗保险数据库中的肿瘤相关数据被利用较多。新型农村合作医疗保险数据区域限制性强，而城镇基本医疗保险数据共享性高。北京大学、复旦大学利用基本医疗保险数据较多。 结论： 中国基本医疗保险肿瘤相关数据利用率较低、可及性较差、共享性不足、区域限制性明显，亟须规范数据使用，提高数据可及性及共享水平，促进健康医疗保险大数据的融合与利用。.
