OBJECTIVE
To study the impact of the number of choices and age on measures of performance in choosing a Medicare prescription drug plan.
DATA SOURCE/STUDY SETTING: One hundred ninty-two healthy individuals age 18 and older, half age 65 or older, in Claremont, California.
STUDY DESIGN
Participants were randomly assigned to 3, 10, or 20 hypothetical drug plans and asked four factual questions. Statistical models controlled for experimental group, age, gender, race, education, income, marital status, and health status.
PRIMARY FINDINGS
Older age and greater number of plans were significantly associated with fewer correct answers. Although older adults were less likely to identify the plan that minimized total annual cost, they were more likely to state that they were "very confident" they chose the correct plan.
CONCLUSIONS
The results raise concerns about the difficulties that older adults may have in navigating the wide range of drug plan choices available.
目的
研究选择数量和年龄对选择医疗保险处方药计划时表现指标的影响。
数据来源/研究背景：加利福尼亚州克莱蒙特市192名18岁及以上的健康个体，其中一半年龄在65岁及以上。
研究设计
参与者被随机分配到3种、10种或20种假设的药品计划中，并被问及4个事实性问题。统计模型对实验组、年龄、性别、种族、教育程度、收入、婚姻状况和健康状况进行了控制。
主要发现
年龄较大和计划数量较多与正确答案较少显著相关。尽管老年人不太可能识别出使年度总成本最小化的计划，但他们更有可能表示自己“非常有信心”选择了正确的计划。
结论
研究结果引发了人们对老年人在面对众多可用药品计划选择时可能遇到困难的担忧。
