应用层次分析法研究不同岗位人员对PACS指标的选择优先度

Research on the PACS selection priorities in different groups by analytic hierarchy process approach

目的:应用层次分析法研究临床医生、放射科人员、影像存档与传输系统(PACS)供应商和计算机工程人员等对PACS指标的选择优先度。方法:在咨询专家的基础上确定PACS的核心指标,再将这些指标分类、整理成层级化的结构。应用层次分析法确定层级化结构一级指标和二级指标的优先权重值。权重值通过一致性检验即是对PACS指标的选择优先度。结果:在3个一级指标中,4种不同岗位人员均将PACS功能和性能的重要性放在首一、首二的位置(权重值为0.3234～0.5876),而将PACS的组件重要性放在次要位置(权重值为0.0667～0.0890)。在13个二级指标中,PACS指标选择优先度差异很大,最大权重值为0.7,最小为0.0338。结论:层次分析法可有效评估不同岗位人员对PACS指标的选择优先度。

Objective： To find the PACS selection priorities in different groups （like clinicians, radiological staff PACS providers and engineers） by using analytic hierarchy process approach. Methods： The key indicators for PACS were identified by consulting experts and classified into different levels. Analytical hierarchy process methodology was used to determine the relative priority weights of each dimension. Results： Among the 3 first level indicators, all the responders put PACS function and performance at No.1 or No.2 （weighted value is 0.3234～0.5876）, and put PACS component at the least important level （weighted value is 0.0667～0.0890）. Among 13 sub-indicators, the relative priority weights varied wildly （from 0.0338 to 0.7）. Conclusion： Analytical hierarchy process can evaluate the PACS selection priorities in different groups effectively.
