The analytic hierarchy process (AHP) is a user-friendly technique that enables a decision marker to elicit subjective values and combine them with more objective data in an explicit, unbiased manner. To determine whether patients are capable of using and willing to use the AHP to help make clinical decisions, the author asked 20 volunteers to perform an AHP analysis of the choice among five screening regimens for colon cancer. The patients were categorized as capable if they completed the analysis in < or = 45 minutes and as willing if they indicated that they would prefer to go through this type of analysis before making a clinical decision. Eighteen (90%) were capable and willing. The difference between this result and 25%, the predefined null hypothesis, is significant: p = 1.6 x 10(-9). These results indicate that AHP-based decision-making aids are likely to be acceptable to and within the capabilities of many patients. If so, they could serve as practical tools for improving the clinical decision-making process.
层次分析法（AHP）是一种用户友好型技术，它能使决策制定者以明确、无偏见的方式引出主观价值，并将其与更客观的数据相结合。为了确定患者是否能够使用以及是否愿意使用层次分析法来辅助临床决策，作者邀请了20名志愿者对五种结肠癌筛查方案的选择进行层次分析法分析。如果患者在45分钟内完成分析，则被归类为有能力；如果患者表示愿意在做出临床决策前进行此类分析，则被归类为愿意。18名（90%）患者有能力且愿意。这一结果与预先设定的零假设25%之间的差异具有显著性：p = 1.6×10⁻⁹。这些结果表明，基于层次分析法的决策辅助工具很可能为许多患者所接受且在其能力范围之内。如果是这样，它们可以作为改进临床决策过程的实用工具。
