To evaluate the efficacy for consumers of two potential enhancements to the Medicare Plan Finder (MPF)-a simplified data display and a "quick links" home page designed to match the specific tasks that users seek to accomplish on the MPF.
DATA SOURCES/STUDY SETTING: Participants (N = 641) were seniors and adult caregivers of seniors who were recruited from a national online panel. Participants browsed a simulated version of the MPF, made a hypothetical plan choice, and reported on their experience.
Participants were randomly assigned to one of eight conditions in a fully factorial design: 2 home pages (quick links, current MPF home page) × 2 data displays (simplified, current MPF display) × 2 plan types (stand-alone prescription drug plan [PDP], Medicare Advantage plan with prescription drug coverage [MA-PD]).
The quick links page resulted in more favorable perceptions of the MPF, improved users' understanding of the information, and increased the probability of choosing the objectively best plan. The simplified data display resulted in a more favorable evaluation of the website, better comprehension of the displayed information, and, among those choosing a PDP only, an increased probability of choosing the best plan.
Design enhancements could markedly improve average website users' understanding, ability to use, and experience of using the MPF.
评估医疗保险计划查找器（MPF）的两项潜在改进措施对消费者的效果，这两项改进措施分别是简化数据显示以及设计一个“快速链接”主页，以匹配用户在MPF上想要完成的特定任务。
数据来源/研究背景：参与者（N = 641）为从全国在线小组招募的老年人及老年护理人员。参与者浏览了MPF的模拟版本，做出了假设性的计划选择，并报告了他们的体验。
参与者在全因子设计中被随机分配到八个条件之一：2种主页（快速链接、当前MPF主页）×2种数据显示（简化、当前MPF显示）×2种计划类型（独立处方药计划[PDP]、含处方药保险的医疗保险优势计划[MA-PD]）。
快速链接页面使人们对MPF有更积极的看法，提高了用户对信息的理解，并增加了选择客观上最佳计划的可能性。简化数据显示使对网站的评价更积极，对所显示信息的理解更好，并且在仅选择PDP的人群中，选择最佳计划的可能性增加。
设计改进可显著提高普通网站用户对MPF的理解、使用能力及使用体验。
