摘要:

目的 基于国内外文献和授权发明专利的对比分析,研究医药数字化的应用热点和发展趋势,为其后续发展提供参考。方法 运用CiteSpace检索2000-2022年CNKI北大核心数据库和Web of Science核心数据库,对国内外文献进行发文量、发文机构、关键词进行统计对比分析,并运用PatSnap软件检索中国数据库(中国专利数据库)、美国数据库(USPTO)以及全球数据库(PatSnap)的授权发明专利,对数量和专利应用细分领域进行统计对比分析。结果 共有国内1 283篇中文文献和国外1 545篇英文文献纳入研究,国内外该领域发文量持续提升,研究热点主要在互联网、信息化以及医疗应用方面,国内更加偏向区块链、大数据等平台搭建,而国外更偏向物联网、云计算等技术应用;另共有美国、中国、全球三大专利数据库的52 208条授权发明专利纳入研究,中国授权发明专利增长强劲,平均增速为24.14%,超过美国8.68个百分点,近3年平均增速为24.50%,全球占比不断提升,从2020年的10.35%提升到2022年的16.48%,中国在图像分析、图像增强、电脑断层扫描仪等方面具有较大发明专利占比,美国在特殊数据处理、药物或药方、生物电信号测量等方面有较明显的创新优势。结论 医药数字化应用热点呈现多元化发展态势,国内外热点呈现差异化,建议国内医药数字化应用发展强调实用性,以精准需求引导数字化技术研发;注重应用性,让数字化技术应用于老百姓的医药健康需求满足,并加强国际合作,联合开拓国际市场。

Abstract:

OBJECTIVE To study the application hotspot and development trend of medical digitalization based on the comparative analysis of domestic and foreign literatures and patents and to provide reference for its subsequent development. METHODS CiteSpace was used to search the CNKI Peking University core database and the Web of Science core database from 2000 to 2022, and statistical comparative analysis of the number of documents issued, the issuing organization, and the keywords of domestic and foreign documents were conducted, and the PatSnap platform was used to search the authorized invention patents of the China database(China Patent Database), the United States database(USPTO), and the global database (PatSnap). The statistics and comparative analysis were carried out on the number and patent application segmentation. RESULTS A total of 1 283 Chinese literatures and 1 545 foreign English literatures had been included in the study. The number of papers published in this field at home and abroad had continued to increase. The research focus was mainly on the Internet, information technology and medical applications. The domestic market was more inclined to build blockchain, big data and other platforms, while the foreign market was more inclined to the Internet of Things, cloud computing and other technology applications. In addition, a total of 52 208 authorized invention patents from the three major patent databases of the United States, China and the world were included in the study. China's authorized invention patents grew strongly, with an average growth rate of 24.14%, which was 8.68 percentage points higher than that of the United States. The average growth rate in the past three years was 24.50%. The global share continued to increase, from 10.35% in 2020 to 16.48% in 2022. China's image analysis, image enhancement, computer tomography scanner and other aspects had a large proportion of invention patents, and the United States had obvious innovation advantages in special data processing, drugs or prescriptions, and bioelectric signal measurement. CONCLUSION The hot spots of medical digital application present a diversified development trend, and the hot spots at home and abroad present differences. It is suggested that the development of domestic medical digital application emphasize practicality, and guide the research and development of digital technology with accurate demand; Pay attention to application, and let digital technology be applied to meet the medical and health needs of the people, and strengthen international cooperation and jointly develop international markets.
