Do Medicare Beneficiaries Under Accountable Care or Medicare Advantage Use Lower Quality Nursing Homes?
Huiying Wang, Cyrus M. Kosar, Momotazur Rahman, Vince Mor. Journal of the American Geriatrics Society, 2024-12-31
Topic: Risk, prevention and care in population studies
Among SNF admissions from 2013 to 2018, the share of ACO-attributed beneficiaries increased from 7.6% to 20.2%, MA enrollees increased from 25.2% to 32.8%, and non-ACO-attributed TM enrollees decreased from 67.2% to 47.3%. Consistently, ACO-attributed beneficiaries were the most likely, while MA enrollees were the least likely to enter high-quality SNFs, regardless of dementia diagnosis. Our findings highlight significant differences in access to high-quality SNFs across Medicare payment models, with ACO-attributed beneficiaries consistently experiencing better access than their MA or traditional Medicare counterparts, regardless of dementia diagnosis. These results underscore the need for further investigation into how payment models influence care quality and access, particularly for vulnerable populations.

Key findings
- Among SNF admissions from 2013 to 2018, the share of ACO-attributed beneficiaries increased from 7.6% to 20.2%, MA enrollees increased from 25.2% to 32.8%, and non-ACO-attributed TM enrollees decreased from 67.2% to 47.3%.
- Consistently, ACO-attributed beneficiaries were the most likely, while MA enrollees were the least likely to enter high-quality SNFs, regardless of dementia diagnosis.
- Our findings highlight significant differences in access to high-quality SNFs across Medicare payment models, with ACO-attributed beneficiaries consistently experiencing better access than their MA or traditional Medicare counterparts, regardless of dementia diagnosis.
- These results underscore the need for further investigation into how payment models influence care quality and access, particularly for vulnerable populations.
Why it matters
This study found that Medicare beneficiaries in accountable care organizations were more likely to enter high-quality nursing homes than those in Medicare Advantage or traditional Medicare, regardless of dementia diagnosis. It highlights differences in access to quality nursing home care across payment models, but does not test any treatment, cure, or prevention for Alzheimer's disease.
