To review the evaluations of computer-based clinical decision support systems (CDSS's).
The literature collected in the MEDLARS, EMBASE, SCISEARCH and INSPEC databases was searched from 1974 to the present. The reference lists of relevant articles were reviewed as were conference proceedings.
Prospective, controlled studies were included. Studies were rated for methodological quality.
Study quality was assessed and data on study setting, subjects, method of allocation, and computer system were collected and verified using a structured form.
There is considerable heterogeneity in both systems evaluated and design features of those systems. Future evaluations of CDSS's should focus on methodological issues in order to enhance overall quality of evaluations.
回顾基于计算机的临床决策支持系统（CDSS）的评估情况。
检索MEDLARS、EMBASE、SCISEARCH和INSPEC数据库中1974年至今收集的文献。查阅了相关文章的参考文献列表以及会议论文集。
纳入前瞻性对照研究。对研究的方法学质量进行评分。
评估研究质量，并使用结构化表格收集和核实有关研究背景、受试者、分配方法和计算机系统的数据。
所评估的系统及其设计特征均存在相当大的异质性。未来对CDSS的评估应关注方法学问题，以提高评估的整体质量。
