背景资料：以电子健康数据库为研究材料的研究越来越多，但单一电子健康数据库的影响还没有得到很好的研究。英国的全科医学研究数据库（GPRD）是少数几个向学术研究人员公开的电子健康数据库之一。本研究分析了使用GPRD的研究，以证明一个单一的公共卫生database.Methodology和结果的科学生产和学术影响：共749个研究发表在1995年和2009年之间的“全科医学研究数据库”为主题，定义为GPRD研究，从Web of Science中提取。截至2009年底，GPRD已吸引了来自22个国家的1251名作者，并在58个研究领域的193种期刊上发表的749项研究中广泛使用。每个GPRD研究被连续研究引用2.7次。此外，大珠三角研究总数迅速增加，预计到2015年将达到1 500项，是2009年底累计数量的两倍。由于17位最多产的作者（占所有作者的1.4%）贡献了近一半（47.9%）的GPRD研究，因此可以累积GPRD研究的成功。GPRD主要用于（但不限于）“药理学和药剂学”、“普通和内科”以及“公共、环境和职业健康”三个研究领域。英国和美国是全球珠三角研究最活跃的两个地区。三分之一的GRPD研究是国际co-authored.Conclusions：公共电子健康数据库，如GPRD将促进科学生产在许多方面。国家一级电子卫生数据库的数据所有者应考虑如何减少访问障碍，并使数据更容易用于研究。
Background: Studies that use electronic health databases as research material are getting popular but the influence of a single electronic health database had not been well investigated yet. The United Kingdom's General Practice Research Database (GPRD) is one of the few electronic health databases publicly available to academic researchers. This study analyzed studies that used GPRD to demonstrate the scientific production and academic impact by a single public health database.Methodology and Findings: A total of 749 studies published between 1995 and 2009 with 'General Practice Research Database' as their topics, defined as GPRD studies, were extracted from Web of Science. By the end of 2009, the GPRD had attracted 1251 authors from 22 countries and been used extensively in 749 studies published in 193 journals across 58 study fields. Each GPRD study was cited 2.7 times by successive studies. Moreover, the total number of GPRD studies increased rapidly, and it is expected to reach 1500 by 2015, twice the number accumulated till the end of 2009. Since 17 of the most prolific authors (1.4% of all authors) contributed nearly half (47.9%) of GPRD studies, success in conducting GPRD studies may accumulate. The GPRD was used mainly in, but not limited to, the three study fields of "Pharmacology and Pharmacy", "General and Internal Medicine', and "Public, Environmental and Occupational Health". The UK and United States were the two most active regions of GPRD studies. One-third of GRPD studies were internationally co-authored.Conclusions: A public electronic health database such as the GPRD will promote scientific production in many ways. Data owners of electronic health databases at a national level should consider how to reduce access barriers and to make data more available for research.
