Objective: To estimate the proportion of seniors with dementia from three independent data sources and their agreement.
Data Sources: The longitudinal Asset and Health Dynamics among the Oldest Old (AHEAD) study (n=7,974), Medicare claims, and death certificate data.
Study Design: Estimates of the proportion of individuals with dementia from: (1) self- or proxy-reported cognitive status measures from surveys, (2) Medicare claims, and (3) death certificates. Agreement using Cohen's kappa; multivariate logistic regression.
Principal Findings: The proportion varied substantially among the data sources. Agreement was poor (kappa: 0.14-0.46 depending upon comparison assessed); the individuals identified had relatively modest overlap.
Conclusions: Estimates of dementia occurrence based on cognitive status measures from three independent data sources were not interchangeable. Further validation of these sources is needed. Caution should be used if policy is based on only one data source.

Prior research demonstrates that local government spending on social policies, excluding health care, is linked to improved population health. Whether such spending is associated with better access to primary care and reduced acute care utilization remains unclear. In this cross-sectional study, we evaluated the associations between county-level social spending and individual-level health care utilization among low-income Medicare beneficiaries, aged ≥65 years, from 2016 to 2018.

Background: Cardiovascular (CV) comorbidities and concurrent medications with risk of heart rate-corrected QT interval (QTc) prolongation can impact treatment decisions and safety discussions for patients with breast cancer. However, limited data are available regarding their prevalence in patients with HR + /HER2- metastatic breast cancer (mBC). We evaluated the prevalence of CV comorbidities, the use of concurrent medications with risk of QTc prolongation, and treatment patterns in patients with newly diagnosed HR + /HER2 - mBC.

Background: The 340B Drug Pricing Program has been controversial since its inception in 1992, a major criticism being that 340B hospitals use more outpatient drugs, and more expensive drugs, because of financial incentives to "make money" through the program. The goal of this study was to determine whether characteristics of patients treated at 340B hospitals, and affiliation of hospitals with NCI-designated cancer centers, would explain higher Part B drug costs and use of more expensive chemotherapy drugs.
Methods: This is an observational study using data from SEER-Medicare and 340B entity database.

Background: To effectively monitor long-term outcomes among cancer patients, it is critical to accurately assess patients' dynamic prognosis, which often involves utilizing multiple data sources (e.g., tumor registries, treatment histories, and patient-reported outcomes).

Background: As percutaneous therapeutic options expand, the optimal management of severe aortic stenosis (AS) and concomitant coronary artery disease (CAD) is being questioned between coronary artery bypass grafting and surgical aortic valve replacement (CABG+SAVR) versus percutaneous coronary intervention and transcatheter aortic valve replacement (PCI+TAVR). We sought to compare perioperative and longitudinal risk-adjusted outcomes between patients undergoing CABG+SAVR versus PCI+TAVR.
Methods: Using the United States Centers for Medicare and Medicaid Services inpatient claims database, we evaluated all patient age 65 and older with AS and CAD undergoing CABG+SAVR or PCI+TAVR (2018-2022).
