在临床研究中,特别是在多中心临床试验中,数据被收集到研究表格中,旨在最大限度地减少记录数据中的错误。必须预见到各种各样的错误,必须设计出发现、审查和纠正错误价值观的手段。介绍了数据编辑系统的一般要求和完成这些任务的方法。描述了一种用于错误检测的通用计算机程序和一种用于更新数据库的方法,该数据库留下原始数据和后续校正的审计跟踪。
In clinical research and particularly in multicenter clinical trials, data are collected onto study forms designed to minimize errors in the recorded data. Errors of various kinds must be anticipated, and it is necessary to devise means to detect, review and correct erroneous values. General requirements of a data editing system and methods for accomplishing these tasks are presented. A general computer program for error detection and a method for updating the data base that leaves an audit trail of the original data and subsequent corrections are described.
