End-of-Life Care for Older Adults With Dementia by Race and Ethnicity and Physicians’ Role
Findings from this cohort study suggest that non-Hispanic Black and Hispanic decedents with dementia received more intensive end-of-life care despite higher rates of billed advance care planning and palliative care counseling than non-Hispanic White decedents. Observed racial and ethnic variations were not explained by differences in the physicians treating them
End-of-Life Care and Health Care Spending for Medicare Beneficiaries With Dementia in Accountable Care Organizations
Using nationally representative data on beneficiaries with dementia at EOL, this quasi-experimental study found no evidence that EOL care processes, outcomes, or spending changed with ACO entry for Medicare fee-for-service beneficiaries vs non-ACO beneficiaries. Alternative payment models to ACOs may be needed to coordinate high-quality care with lower spending for beneficiaries with dementia at the EOL
Comparing Gold-standard Copayment and Coinsurance Values From Claims Processing Engines to Values Derived From Behavioral Health Claims Databases
BACKGROUND: While researchers use patient expenditures in claims data to estimate insurance benefit features, little evidence exists to indicate whether the resulting measures are accurate. OBJECTIVE: To develop and test an algorithm for deriving copayment and coinsurance values from behavioral health claims data. SUBJECTS: Employer-sponsored insurance plans from 2011 to 2013 for a national managed behavioral health organization (MBHO). MEASURES:…
The Mental Health Parity and Addiction Equity Act Evaluation Study
OBJECTIVE: The federal Mental Health Parity and Addiction Equity Act (MHPAEA) sought to eliminate historical disparities between insurance coverage for behavioral health (BH) treatment and coverage for medical treatment. Our objective was to evaluate MHPAEA's impact on BH expenditures and utilization among "carve-in" enrollees. METHODS: We received specialty BH insurance claims and eligibility data from Optum, sampling 5,987,776 adults enrolled i…
The Associations of Area-Level Violent Crime Rates and Self-Reported Violent Crime Exposure with Adolescent Behavioral Health
Personality disorders and body weight
We examine the impact of Axis II personality disorders (PDs) on body weight. PDs are psychiatric conditions that develop early in life from a mixture of genetics and environment, are persistent, and lead to substantial dysfunction for the affected individual. The defining characteristics of PDs conceptually link them with body weight, but the direction of the relationship likely varies across PD type. To investigate these links, we analyze data f…
