Hypothesis
How does cognitive function change over the last five years of life among Medicare beneficiaries?
Conclusion
The study reveals ten distinct cognitive function trajectory groups among Medicare beneficiaries in their last five years of life.
Supporting Evidence
- The study harmonized cognitive function data into four categories: no impairment, memory loss, mild cognitive impairment, and dementia.
- Machine learning algorithms were used to predict cognitive function trajectory class clusters.
- The research included nearly two million Medicare beneficiaries to analyze cognitive function trajectories.
Takeaway
This study looks at how people's thinking skills change as they get older, especially in the last years of their life.
Methodology
Data from healthcare claims and clinical assessments were harmonized and analyzed using group-based trajectory models.
Participant Demographics
Medicare beneficiaries who died in 2019, age 50 or older at death.
