Medicare Advantage (MA) plan selection may differ between older adults with or without dementia in unexplored ways. This study aims to characterize MA plan choice among those with dementia.
We used the 2010 to 2018 waves of the Health and Retirement Study with linked Medicare enrollment data to identify MA respondents ≥ 65 years, with and without dementia. Conditional logit models examined how characteristics of MA plans affected choice.
Among respondents overall, there were no differences between those with versus without dementia regarding how plan out-of-pocket cost, star rating, and type affected choice. Among the dual eligible group, those with versus without dementia were more likely to choose Special Needs Plans (difference in log odds: 0.804, = 0.007).
There were few differences in how MA plan characteristics affected choice among older adults with and without dementia. Older adults with dementia may make similar MA plan choices as those without.
医疗保险优势（MA）计划的选择在患有或未患痴呆症的老年人中可能存在未被探索的差异。本研究旨在描述痴呆症患者的MA计划选择情况。
我们使用2010年至2018年的健康与退休研究以及相关的医疗保险参保数据，以识别年龄≥65岁、患有和未患痴呆症的MA受访者。条件logit模型研究了MA计划的特征如何影响选择。
在所有受访者中，患有和未患痴呆症的人在计划自付费用、星级评级和类型如何影响选择方面没有差异。在双重资格组中，患有痴呆症和未患痴呆症的人更有可能选择特殊需求计划（对数优势差异：0.804，P = 0.007）。
MA计划特征对患有和未患痴呆症的老年人选择的影响几乎没有差异。患有痴呆症的老年人可能会做出与未患痴呆症的老年人类似的MA计划选择。
