Functional Trajectories at the End of Life for Individuals with Dementia: Issue Brief

For this project, we used a sample of decedents from the 2000-2012 Health and Retirement Study to understand the trajectories of functional decline of older adults with dementia near the EOL, and how these trajectories differ from those of people without dementia. In addition, we examined whether and how these trajectories vary by other patient characteristics such as demographics, comorbidities, and access to caregiving.

Accuracy of Diagnosis and Health Service Codes in Identifying frailty in Medicare Data

Background: Capturing frailty within administrative claims data may help to identify high-risk patients and inform population health management strategies. Although it is common to ascertain frailty status utilizing claims-based surrogates (e.g. diagnosis and health service codes) selected according to clinical knowledge, the accuracy of this approach has not yet been examined. We evaluated the accuracy of claims-based surrogates against two clinical definitions of frailty.

Validation of a Claims-Based Frailty Index Against Physical Performance and Adverse Health Outcomes in the Health and Retirement Study

Background: A claims-based frailty index (CFI) was developed based on a deficit-accumulation approach using self-reported health information. This study aimed to independently validate the CFI against physical performance and adverse health outcomes.
