INTRODUCTION
One-third of Medicare beneficiaries are enrolled in Medicare Advantage (MA). Yet, little is known about MA beneficiaries diagnosed with Alzheimer's disease (AD) and AD-related dementias (AD/ADRD).
METHODS
We calculated the prevalence of AD/ADRD diagnoses in 2014 and 2016 in three MA plans. We determined the demographic characteristics of beneficiaries diagnosed with AD/ADRD, and whether they disenrolled from the MA plan for any reason within 364 days from the index date.
RESULTS
In 2014 and 2016, the overall prevalence of AD/ADRD diagnoses was 5.6% and 6.5%, respectively. In 2016, AD/ADRD beneficiaries were on average 82.4 (SD = 7.4) years of age, 61.8% female, and had multiple comorbidities. By 364 days post-index date, 32% of beneficiaries with AD/ADRD had disenrolled from their plan. The demographic characteristics of 2014 beneficiaries with diagnosed AD/ADRD were similar to their 2016 counterparts.
DISCUSSION
The prevalence of AD/ADRD diagnosis in MA is lower than rates reported in Medicare fee-for-service.
引言
三分之一的医疗保险受益人参加了医疗保险优势计划（MA）。然而，对于被诊断患有阿尔茨海默病（AD）和AD相关痴呆症（AD/ADRD）的MA受益人，我们知之甚少。
方法
我们计算了2014年和2016年三个MA计划中AD/ADRD诊断的患病率。我们确定了被诊断患有AD/ADRD的受益人的人口统计学特征，以及他们在索引日期后的364天内是否因任何原因退出MA计划。
结果
2014年和2016年，AD/ADRD诊断的总体患病率分别为5.6%和6.5%。2016年，AD/ADRD受益人平均年龄为82.4岁（标准差=7.4），女性占61.8%，且有多种合并症。到索引日期后364天，32%的AD/ADRD受益人已退出其计划。2014年被诊断患有AD/ADRD的受益人的人口统计学特征与2016年的类似。
讨论
MA中AD/ADRD诊断的患病率低于医疗保险按服务收费报告的比率。
