项目摘要

Using currently available internet-based date entry systems for clinical trials, it is necessary to re-enter data that are already stored in hospital information systems. This is not only troublesome to physicians, but also may generate inputting errors and debase data quality. In this study, we developed data entry system for clinical trials, using which patients' laboratory data stored in hospital information system are automatically transferred to fulfill data entry form. The system is made up of the four part : namely, (1) server module in coordinating center, (2) WWW browser for physicians, (3) HTTP-HL7 gateway module which communicate hospital communication system with HL7 and WWW browser with HTTP. In HMTL-based data form sent from the data center server, information concerning datum, which should be obtained from hospital information, are embedded using "hidden" variable attributes. And, as different from ordinary data form, HTTP-HL7 gateway located in hospital is specified as data form posting site, instead of the data center server. When a physician submits the data form, its contents are sent to HTTP-HL7 gateway server and, in return, date form fulfilled with laboratory data stored hospital information system is sent to the WWW browser. Then physician submit the returned form to data center.

使用目前可用的基于互联网的临床试验数据录入系统，有必要重新录入已经存储在医院信息系统中的数据。这不仅给医生带来麻烦，还可能产生输入错误，降低数据质量。在本研究中，我们开发了临床试验数据录入系统，利用该系统可以自动调用医院信息系统中存储的患者的实验室数据，完成数据录入表格。该系统由四部分组成：(1)协调中心服务器模块；(2)医生WWW浏览器；(3)HTTP-HL7网关模块，实现医院通信系统与HL7、WWW浏览器与HTTP的通信。在从数据中心服务器发送的基于HMTL的数据表单中，应该从医院信息中获取的与数据有关的信息被嵌入到使用“隐藏的”变量属性。与普通数据表单不同的是，数据表单发布站点不是数据中心服务器，而是位于医院的HTTP-HL7网关。当医生提交数据表单时，其内容被发送到HTTP-HL7网关服务器，而存储有医院信息系统的实验室数据所填写的数据表单被发送到WWW浏览器。然后医生将退回的表格提交给数据中心。
