Use of long-term services and supports among dual-eligible beneficiaries with Alzheimer's disease and related dementias

Background: To respect people's preference for aging in place and control costs, many state Medicaid programs have enacted policies to expand home and community-based services as an alternative to nursing facility care. However, little is known about the use of Medicaid long-term services and supports (LTSS) at a national level, particularly among dual-eligible beneficiaries with Alzheimer's disease and related dementias (ADRD). Methods: Using Medicare and Medicaid claims of 30 states from 2016, we focused on dual-eligible beneficiaries 65 years or older with ADRD and described their use of any form of LTSS and sub-types of LTSS (home-based, community-based, and nursing facility services) across states. Results: We found that 80.5% of dual-eligible beneficiaries with ADRD received some form of Medicaid LTSS in 2016. The most common LTSS setting was nursing facility (46.7%), followed by home (31.5%) and community (12.2%). There was sizeable state variation in the percentage of dual-eligible beneficiaries with ADRD who used any form of LTSS (ranging from 61% in Maine to 96% in Montana). The type of LTSS used also varied widely across states. For example, home-based service use ranged from 9% in Maine, Arizona, and South Dakota to 62% in Oregon. Nursing facility services were the most common type of LTSS in most states. However, home-based service use exceeded nursing facility use in Oregon, Alaska, and California. Conclusions: Our findings suggest substantially different use of LTSS across states among dual-eligible beneficiaries with ADRD. Given the importance of LTSS for this population and their families, a deeper understanding of state LTSS policies and other factors that contribute to wide state variation in LTSS use will be necessary to improve access to LTSS across states.
